I’ve just published the diagnostics version of the Move Facebook Events Box to Top script.

It’s made to help in the tracing of any kind of problem which may keep the script from working for someone.

FacebookEventsToTop_Diagnostics

There shouldn’t be need to say that the diagnostics version is just for the ones who are having problems with the script.

It has happened almost no time since the last update (I made it yesterday), but I had to make a new release to correct one remaining problem which made the script not to work sometimes with the new site structure (specifically when returning to home without reloading after some kind of actions, for example, clicking the “Return to home” link after cleaning up all the pending requests).

You may have not seen the problem, but anyway I recommend the update because Facebook keeps changing the site structure and this is the best working release (its been doing its work flawlessly in every case I’ve tested it in by now).

]]> If you have a website with Google Analytics configured and want to be able to track its visits without needing to go to the Analytics Site (except when you need more advanced reports), then this online tool is for you…

GoogleAnalyticsVisits_Visits

It’s very simple to use… You just need to access the following URL:

And this screen will appear (below I’ll explain how to make this service look like an application and even make a special desktop shortcut):

GoogleAnalyticsVisits_Login

If you press Login, you’ll be taken to the Google Apps site, which will ask you for your login information (unless you’re already logged in):

GoogleAnalyticsVisits_Authenticate



PadlockIconNotice: as this application was developed using the Google Analytics API, your login information does not go through the NeoEGM.com site, so there’s no way to record it. The Javascript source code is available for you to check it out.



After that, the Permission Grant screen will appear…

GoogleAnalyticsVisits_Grant

You must press the “Grant access” button in order for the analytics statistics data to be accessed by the application. Again: there’s absolutely no harm in doing this since there’s no record at all being saved by the NeoEGM.com site.

After the “Grant access” button has been pressed, you’ll get the account listing screen…

GoogleAnalyticsVisits_Accounts

There, you have to choose the desired account to monitor. You can also easily copy the account link to bookmark it or to access it directly whenever you want (without having to pass through the accounts screen)… This is very useful when you have a bunch of sites to monitor and want to open all the links at the same time…

GoogleAnalyticsVisits_IndexCopyLinks

Anyway, I recommend opening one of them first, to do all the authentication stuff, and then open all the remaining ones…

Well, finally, we’ll get to the visits screen, which show today’s and yesterday’s visits and pageviews…

GoogleAnalyticsVisits_VisitsExplained

It’ll get automatically updated each 5 minutes… So you can the window open and look it from time to time… Of course, you must take into account that the Google Analytics service does not refresh its internal data each time a user visits your site… It may take several minutes (usually 1 hour) for you to see changes in your visits…

Well, that’s all about the application… Below are further instructions to make it have a more friendly interface…

GNU GPL v3 As usual, Google Analytics Visits is licensed under the GNU GPL v3…

PadlockIconSecurity tip: if, for any reason, you ever wanted to revoke the access you have granted to any web application to access your Google data, you can visit the “change authorized sites” Google Accounts facility.

Enjoy it :)

How to convert it into an application (or at least make it look like one :))

As you will have probably noticed in the previous screenshots, there was was no address bar, navigation buttons, status bar nor anything related with a browser in the windows I’ve shown. How did I do that?

PrismLogoCleanThere is an excellent Firefox add-in called Prism which lets you convert any website into a desktop application. It does even create the shortcuts for you!

How does it work?

Well, first of all, you need to have the Firefox browser and install the Prism extension:

After that, you have to access the URL you want to convert into an application and go to Tools->Convert Website to Application…

GoogleAnalyticsVisits_ConvertWebsiteToApplication

Then, you’ll get to the Prism application configuration dialog…

GoogleAnalyticsVisits_Prism

There, you have to configure how you wish your new application to behave (in this case, it won’t have anything related to a browser and will create a Desktop shortcut icon)…

And that’s all! You’ll have your Google Analytics Visits desktop shortcut icon…

GoogleAnalyticsVisits_DesktopIcon

Enjoy it :)

]]> Let’s say you’re searching for videos (or webpages if you wish) of some topic. And you navigate through lots and lots of them… Opening new tabs and even jumping between links without leaving the previous URL open somewhere else (this commonly happens when you click any “Related Video” on YouTube, since it automatically opens on the same tab)…

It would be really tedious to go through each of your tabs rescuing all the interesting URLs to save them…

Also, if you could save them as bookmarks (assuming you don’t care about the browsing history), it’s not really simple to just get the URLs to copy them or to send them to somebody else…

For this (and for any other case you could find), I developed the “List Open URLs” Firefox Add-on…

ListOpenURLs_Menu

As you can imagine, its really simple to use…

You just click the Tools menu “List Open URLs” option and you’ll get a prompt asking whether or not you want to take into account the history of each of the tabs…

ListOpenURLs_HistoryQuestion

If you choose not to (“Cancel” button), then it will generate a listing including only the currently opened URLs…

ListOpenURLs_DumpNoHistory

But if you, instead, clicked “OK”, then you’d get a full listing, including the history of each tabs (the URLs in the “back” and “forward” buttons)…

ListOpenURLs_DumpHistory

Finally, if you want to copy the entire text, you can simply right click it and choose “Select All”…

ListOpenURLs_SelectAll

And, after that, right click it again and choose “Copy”…

ListOpenURLs_Copy

That’s all… You’ll have the text in your clipboard…



GNU GPL v3 As usual, List Open URLs is licensed under the GNU GPL v3…

If you want it, just click here to download:

If you like it, please add a review at Firefox’s Add-on site so it can get out of the “experimental” state…

]]> There are lots of people (like me) who just use the HTML mode of the WordPress Editor… Sometimes, you cannot just disable the WYSIWYG editor (in my case, I cannot do it because I use the qTranslate plugin to enable the creation of posts in different languages)… For this people, having the Visual editor tab, might be a very big problem…

Lets say you’re writing a post in the HTML tab…

Remove_Visual_Tab_HTML

And you click by mistake the Visual tab…

Remove_Visual_Tab_Visual

When you go back to the HTML mode, you’ll see, probably with a bit of anger, that all your code has just been broken…

Remove_Visual_Tab_HTML_Broken

So what’s the solution to prevent this problem from happening again? Well, what better than just removing the tab?

Remove_Visual_Tab_Removed

I’ve made a script to do this… I didn’t make it a WordPress plugin for two reasons: first, to avoid making the server work more without reason for things you can easily do on the client side, and second, to allow without problems the different users of your blog to choose the writing method they prefer (may be some users do use the visual editor)…



Firefox_small This script needs Firefox and the GreaseMonkey add-on (I really recommend installing it since it gives you the ability to run this kind of “web site customizing scripts”)…



First of all, assuming you have Firefox installed, you have to install the GreaseMonkey add-on (click “Add to Firefox” in the following link):



Then, once it is installed and running (you must restart Firefox when asked for), there will be a colored monkey face in the status bar (if it is gray, you must enable the engine by clicking on it):

GreaseMonkey_On

After that, you are finally prepared to install the script…



GNU GPL v3 As usual, Hide WordPress Visual Editor Tab is licensed under the GNU GPL v3 (attached)…



Now, finally, the link…

Update: new version 1.01 which makes it also work when creating new posts and pages (it just worked when editing).

]]> With this online tool, you can easily escape and unescape strings (among other powerful things, explained below)…

If you want to bookmark it, you may prefer this shorter address: http://www.neoegm.com/software/intelligent-escaper-unescaper/. [Press the right mouse button and select the option offered by your browser to add it to your bookmarks/favorites.]


As you can see, there are several features… I’ll explain them one by one…

Escape

Calls the escape Javascript function, which encodes the special characters (with some exceptions).

Example:

Hello, this is a test
Hello%2C%20this%20is%20a%20test

Escape (Forced)

Encodes every character, no matter whether it is special or not. Ideal to make the strings not easily readable.

Example:

Hello, this is a test
%48%65%6C%6C%6F%2C%20%74%68%69%73%20%69%73%20%61%20%74%65%73%74

Unescape

Calls the unescape Javascript function, which decodes every encoded character. (The ones with the form %XX or %uXXXX).

Example 1:

Hello%2C%20this%20is%20a%20test
Hello, this is a test

Example 2:

%48%65%6C%6C%6F%2C%20%74%68%69%73%20%69%73%20%61%20%74%65%73%74
Hello, this is a test

Escape URL

Encodes the special characters, but respecting the URL syntax. It’s not the same as the “encodeURI” option, since this latter one calls the encodeURI Javascript function, which does not encode the following characters: 

; , / ? : @ & = + $ - _ . ! ~ * ' ( ) #

While this one just does not encode them where corresponding. Parameters, anchors and Unicode characters are supported…

Example:

http://www.example.com:84/This is my file named niño: the named place.doc
http://www.example.com:84/This%20is%20my%20file%20named%20ni%F1o%3A%20the%20named%20place.doc

Escape URL (Forced)

Similar to “Escape URL”, but forcing the normal character encoding as much as possible (without including the host). Ideal to make URLs hard to read at first glance.

Example:

http://www.example.com:84/This is my file named niño: the named place.doc
http://www.example.com:84/%54%68%69%73%20%69%73%20%6D%79%20%66%69%6C%65%20%6E%61%6D%65%64%20%6E%69%F1%6F%3A%20%74%68%65%20%6E%61%6D%65%64%20%70%6C%61%63%65%2E%64%6F%63

Escape URL (Forced + Host)

Similar to “Escape URL”, but forcing the normal character encoding as much as possible (host included). Ideal to make URLs hard to read at first glance.

Note: this syntax is not supported in some browsers.

Supported browsers: Internet Explorer, Google Chrome.
Unsupported browsers: Firefox, Lynx.

In the case of Firefox, the string gets decoded correctly (if the URL is valid), but it doesn’t open, you have to open it again with the decoded address (selecting it and pressing Enter). If the host doesn’t contain any dot, “www.” y “.com” al added automatically.

If you have support information for any other browser, please tell me and I’ll add it.

Ejemplo:

http://www.example.com:84/This is my file named niño: the named place.doc
http://%77%77%77.%65%78%61%6D%70%6C%65.%63%6F%6D:84/%54%68%69%73%20%69%73%20%6D%79%20%66%69%6C%65%20%6E%61%6D%65%64%20%6E%69%F1%6F%3A%20%74%68%65%20%6E%61%6D%65%64%20%70%6C%61%63%65%2E%64%6F%63

Intelligent Escape

This function is an intelligent version of “Escape”. It encodes the corresponding characters, but without re-encoding the already encoded data.

Example:

Partially%22%20encoded%20string. And I added this part.
Partially%22%20encoded%20string.%20And%20I%20added%20this%20part.

If we just pressed “Escape”, we would have received:

Partially%2522%2520encoded%2520string.%20And%20I%20added%20this%20part.

Intelligent Unescape

Calls the unescape Javascript function repeatedly until there’s nothing remaining to be decoded. Useful when a string was encoded several times.

Example:

%25%34%38%25%36%35%25%36%43%25%36%43%25%36%46
Hello

If we just pressed “Unescape”, we would have received:

%48%65%6C%6C%6F

Parse URL Parameters

It breaks a URL into its corresponding parameters. The anchor is left without unescaping in the end.

Example:

http://www.example.com:81/path/path/hello.php?a=3&b=Good%20Morning&c=El%20Ni%F1o#test-anchor
http://www.example.com:81/path/path/hello.php

a=3
b=Good Morning
c=El Niño

#test-anchor

Make URL with Parameters

Reconstructs a URL based in the specified URL + parameters + anchor.

Example:

http://www.example.com:81/path/path/hello.php

a=3
b=Good Morning
c=El Niño

#test-anchor

http://www.example.com:81/path/path/hello.php?a=3&b=Good%20Morning&c=El%20Ni%F1o#test-anchor

Escape +

It encodes the + characters. They are not escaped by the other functions, with the exception of “Escape (Forced)”.

Escape #

It encodes the # characters. They are not escaped by the other functions, with the exception of “Escape (Forced)”.

Escape: <char>

It encodes the characters specified in the input box.

encodeURI

Calls the encodeURI Javascript function.

decodeURI

Calls the decodeURI Javascript function.

encodeURIComponent

Calls the encodeURIComponent Javascript function.

decodeURIComponent

Calls the decodeURIComponent Javascript function.

]]> The GCC compiler (or G++) does not always work with our source code files just as we would expect it to. This specially happens when there are special characters in our files (the ones with ASCII codes higher than 127).

Take the following program as a sample (the strings are written in spanish):

#include <iostream>
using std::cout;
using std::cin;
using std::endl;

#include <string>
using std::string;

int main()
{
	string sDummy;

	cout << "Por favor ingrese su contraseña: ";
	cin >> sDummy;

	cout << endl;
	cout << "Su contraseña es inválida, por favor verifíquela e inténtelo nuevamente. Ha ingresado: '" << sDummy << "'." << endl;

	return 0;
}

Let’s compile it… 

g++ TestChars.cpp -o TestChars.exe

And execute it… We can easily imagine the output… But… This is what we get:

Por favor ingrese su contrase±a: contraseña

Su contrase±a es invßlida, por favor veriffquela e intTntelo nuevamente. Ha ingresado: 'contraseña'.

Notice that the string that we’ve just typed (“contraseña”) gets correctly printed, while the ones hard-coded in the program don’t.

So… What can we do?

Well, there are some compiler command line parameters ready to help us… They are the finput-charset and fexec-charset command line arguments…

Both take as additional parameter a charset name from the ones supported by the compiler…

For the interested ones, here is the output of the charsets supported by the library that GCC uses to make the conversion… They may not be the same on every system…

The first parameter, finput-charset, is the charset used to read the source code files… The second one, fexec-charset, is the used to store the strings and character constants in the executable file, so they will be shown correctly while running…

So, assuming you’re writing your source files in iso-8859-1 (the most common charset on Windows platforms) and want to show them while running in cp437 (the DOS console charset), we could call the compiler like this:

g++ TestChars.cpp -o TestChars.exe -finput-charset=iso-8859-1 -fexec-charset=cp437

And what do we expect to get? :)

Por favor ingrese su contraseña: contraseña

Su contraseña es inválida, por favor verifíquela e inténtelo nuevamente. Ha ingresado: 'contraseña'.

Everything worked just the way we expected! :)

Now, finally, I’ll show how to configure these command line options for the wxDev IDE…

First of all, I must say there are two ways to set compiler options: global options and project options… As you may imagine, the first ones are applied to every compiled project, while the latter just get applied to the currently opened project (they are set in a per project basis)…

To set the parameters in the global compiler options you must got to the Tools menu and then open the Compiler Options item…

Main_Menu_EN

After that, you simply enter the following string (the parameters) into the “Add the following commands when calling compiler” box:

-finput-charset=iso-8859-1 -fexec-charset=cp437

If there are already other parameters configured, you should append them…

Main_Compiler_Options_Filled_EN

They will be sent to both the C compiler and the C++ compiler…

The other alternative is to set the same parameters in the project options…

First, we open the project options… Either going to Project->Project Options or right clicking the project and going to “Project Options”…

Project_Menu_EN

Then, we go to the Parameters page and paste the parameters string in the two compiler boxes… Both parameters can be entered either in a single line or broken apart… Just as before, if there are already other parameters configured, you should append them…

Project_Options_Parameters_Filled_EN

Whell, that’s all… Most IDEs will have similar options!

]]> Just as I published some days ago the Simple C++ String Class as a C++ learning exercise, now I am freeing a Simple C++ List Class.

The standard library has a list class. But, while learning, it’s a good idea to know how to develop your own list class.

That’s why I made the List class. It’s not intended for professional projects (for them, you should use the standard library’s list), but as help to learn C++.

template <class TYPE>
class List
{
	/* ... */

public:
	//Construction and destruction
	List() { /* ... */ }
	~List() { /* ... */ }
	
	List(const List& rlList) { /* ... */ }
	
	//Assignment operator
	List& operator=(const List& rlList);

	//Information
	int Length() { /* ... */ }
	bool Empty() { /* ... */ }

	//Element managing
	int Add(TYPE& rtData);
	TYPE* Elem(int nPos);
	bool Delete(int nPos);
	void DeleteAll();
	
	//Search
	int Find(TYPE& rItem, int nStartAt = 0);

	//Operadores
	TYPE& operator[](int nPos) { /* ... */ }	//Elem
	int operator<<(TYPE& rdData) { /* ... */ }	//Add

protected:
	void FreeList();
	void Init() { /* ... */ }
};

//Output
template <class TYPE>
std::ostream& operator<<(std::ostream& oStream, List<TYPE>& rlList);

This is a sample project made to explain the List class usage.

#include <iostream>
	using std::cout;
	using std::cin;
	using std::endl;

#include "List.h"
#include "String.h"

int main(int argc, char *argv[])
{
	cout << "List sample project" << endl;
	cout << "-------------------" << endl << endl;


	//-----------------------------
	cout << "> Creating a list of strings... An empty string finishes the list..." << endl << endl;

	List<String> lStrings;
	String sTmp;
	
	do
	{
		cout << "> String " << lStrings.Length()+1 << ": ";
		cin >> sTmp;
		
		if (sTmp.Length())
			lStrings.Add(sTmp);
	} while (sTmp.Length());
	
	cout << endl << "> Entry finished. " << lStrings.Length() << " string(s) loaded." << endl << endl;
	
	cout << "> Printing list..." << endl << endl;
	
	cout << lStrings;

	cout << endl;
	//-----------------------------
	
	
	//-----------------------------
	do
	{
		cout << "> Type a string to find in the list (exact match) [empty = end]: ";
		cin >> sTmp;

		if (sTmp.Length())
		{
			int nFound = lStrings.Find(sTmp);
			
			if (nFound != -1)
			{
				lStrings.Delete(nFound);

				cout << "> String \"" << sTmp << "\" found at position " << nFound+1 << " and removed." << endl << endl;
				
				cout << "> Printing list..." << endl << endl;

				if (!lStrings.Empty())
					cout << lStrings;
				else
				{
					cout << "[Empty list]" << endl << endl;
					break;
				}
			}
			else
				cout << "> String \"" << sTmp << "\" not found." << endl;
		}
		
		cout << endl;
	} while (sTmp.Length());
	
	cout << endl;
	//-----------------------------

	//-----------------------------
	cout << "> Now getting a bit more complex... Let's create a list of lists of strings... An empty string finishes the list and an empty first string finishes the list of lists..." << endl << endl;

	List< List<String> > lLists;
	List<String> lTmpList;
	int nStrings = 0;

	do
	{
		lTmpList.DeleteAll();
		
		cout << "> Loading list " << lLists.Length()+1 << "..." << endl;
		
		do
		{
			cout << "\t> String " << lTmpList.Length()+1 << ": ";
			cin >> sTmp;
			
			if (sTmp.Length())
			{
				lTmpList.Add(sTmp);
				nStrings++;
			}
		} while (sTmp.Length());
		
		if (lTmpList.Length())
			lLists.Add(lTmpList);
	} while (lTmpList.Length());
	
	cout << endl << "> Entry finished. " << lLists.Length() << " list(s) loaded, " << nStrings << " string(s) loaded." << endl << endl << endl;

	cout << "> Printing lists (standard method)..." << endl << endl;

	cout << lLists;

	cout << endl;
	
	cout << "> Printing lists (custom method)..." << endl << endl;
	
	for (int i = 0; i < lLists.Length(); i++)
	{
		List<String> *plList = lLists.Elem(i);

		if (plList)
		{
			cout << "- List " << i << endl << endl;
			cout << *plList;
			cout << endl;
		}
	}
	//-----------------------------

    return 0;
}

And this is its output:

This project also uses the Simple C++ String Class to show the List class working with custom classes. Exactly the same code could be without problem by simply replacing “String” with “string” and including the standard library’s string header.

The code completely is portable.

It’s been developed, compiled and tested using wxDev-C++ for Windows with the MinGW compiler (included in the bundle).

I’ve also tested the project for memory leaks using the cppMemDbg – Easy to use C++ memory leak detection library and it found no problems at all…

]]> Everybody knows the Pinball game that appeared with Windows 95 Plus!… It’s still in current Windows versions…

Pinball_Cracker_Game

Although it may seem incredible, there are still some fanatics of this game…

I’ve made this program in 1999 (some time ago 8-)) to let you modify the High Scores so you could make those fanatics believe you had beaten them…

Pinball_Cracker_Game_High_Scores

(You should be a little more subtle than me)

After starting, you must take into account I wrote this program when I was 13… So I’m dismissed for any possible criticism… Now, after that disclaimer, we can continue…

The tool is very easy to use…

Pinball_Cracker_Main

But has some hidden features that make it a bit more powerful…

There are 3 easter eggs (it seems I really enjoyed writing them at that time) that unlock 3 special options… They must be made in the following order, otherwise they won’t work…

First of all you must open the about screen and wait for the legend to scroll 5 times (you can make it go faster by pressing Shift+U several times)… If you have the Caps Lock enabled you must not use the Shift key to press the U… (As an additional tip, not really useful anyway, you can make the text scroll slower again by pressing Shift+D)

Pinball_Cracker_About_1

Then, you must click sequentially the 4 crosses at the corners in this order: lower-right, upper-left, upper-right, lower-left. Anyway, if you start with the lower-right, the lines will guide you. That will enable the first “cheat”, which unlocks the “Show Verification Code” option at the main screen. The verification code is some sort of checksum used by the game to verify you didn’t modify the high scores.

Pinball_Cracker_About_2

The second cheat is the easiest… You must right-click the upper-right cross while holding Shift and then release it and left-click the lower-right cross… The “Print Hall of Fame” option will be unlocked… It’s a completely unuseful option, but it seems I wanted to develop my printing ability at that time… So don’t ask :)

Pinball_Cracker_About_3

Finally, the latest easter egg (and the most useful of all) gets unlocked by doing the following steps: with the focus (the dotted rectangle) in the upper button, press Shift+P (again the same thing about Caps Lock)…

Pinball_Cracker_About_4

Then, move the focus to the next button by pressing Tab and press Shift+C…

Pinball_Cracker_About_5

That’s all… Now you’ll have enabled the possibility of exporting the scores to a .REG file so you can simply double click it on any computer to set the new scores…

This is how the main screen will now look like…

Pinball_Cracker_Cheats

This tool was originally written in Visual Basic 6, so I opened the project, updated it to the .NET Framework 2.0 (VB.NET) and then fixed some bugs, corrected some things and prepared it to be published… I’m freeing the source code just for the ones who may have curiosity, but I don’t recommend taking it as model for anything…

To run it, you’ll need the .NET Framework 2.0 and the Microsoft Visual Basic PowerPacks 1.2.

UPDATE: I’ve just uploaded the required Visual Basic PowerPacks redistributable file since the ones offered online by Microsoft (2.0 & 3.0) does not fulfill the required dependencies. They seem to be different things. This redistributable is needed in order to be able to open the About box and unlock the special options.

]]> Facebook has got very interesting features… One of them is the possibility of having a reminder of your friend’s birthdays and events you have subscribed to…

But (there’s always a but 8-))… They’re not in a very handy place…

So… I’ve decided to make a script to move them to the top :)

FacebookEventsToTop

Firefox_small This script needs Firefox and the GreaseMonkey add-on (I really recommend installing it since it gives you the ability to run this kind of “web site customizing scripts”)…



First of all, assuming you have Firefox installed, you have to install the GreaseMonkey add-on (click “Add to Firefox” in the following link):



Then, once it is installed and running (you must restart Firefox when asked for), there will be a colored monkey face in the status bar (if it is gray, you must enable the engine by clicking on it):

GreaseMonkey_On

After that, you are finally prepared to install the script…



GNU GPL v3 As usual, Facebook Events To Top is licensed under the GNU GPL v3 (adjunta)…



There are two versions of the script… One for Firefox version 3.5 and later and one for previous Firefox versions… I strongly recommend using the newest one wherever it’s possible since it is much more efficient (I even recommend installing the latest stable Firefox version if you can)…

You just have to click the corresponding script version link and (if GreaseMonkey is correctly installed and running), an installation dialog will appear asking for your confirmation… We just press “Install” after the expiration of the security time and we’re done…



UPDATE (2009-08-19): I’ve released the 1.1 version to solve the problem that made the events box not going to the top sometimes when loading the page (or reloading). [Recommended update]

UPDATE (2009-09-15): I’ve released the 1.2 version to solve the problem that made the script not to work on some accounts due to Facebook site structure changes. [Recommended update]

UPDATE (2009-09-16): Version 1.2.1 released to solve one remaining problem that made the script not to work sometimes with the new site structure (specifically when returning to home without reloading after some kind of actions, for example, clicking the “Return to home” link after cleaning up all the pending requests). [Recommended update]

UPDATE (2009-10-12): I’ve just added the diagnostics versions below just in case the script doesn’t work for somebody.

UPDATE (2010-02-16): I’ve released the 1.3 version to solve the problem that made the script not to work due to Facebook site structure changes. [Recommended update]



Now, finally, the links…



Once installed, it will get active while browsing any Facebook page and will bring your Events box to the top just as expected…

FacebookEventsToTop_GM

This menu option just appears when browsing a Facebook page, otherwise, the script will remain inactive.

Enjoy it! :)



Diagnostics version (just in case of troubles)

FacebookEventsToTop_Diagnostics

If you’re having any troubles with the script, please download the corresponding diagnostics version below and send me, via the contact form, the text that appears in the top of the page after logging in to Facebook and accessing http://www.facebook.com/home.php.

If possible, send me any related error appearing at the “Errors” section of the Firefox’s Error Console (located in the Tools menu, option “Error Console”). You should open it, press “Clear” to clear all errors and click the “Errors” option so there won’t be Warnings and Messages. Right after that, you should open the Facebook URL I wrote above.

Note: it’s important to make sure that no other GreaseMonkey script is interfering with this script. So before making any problem report, try disabling any other GreaseMonkey script you are running. You can do this by right clicking the GreaseMonkey icon in the status bar, going to “Manage User Scripts” and then unchecking the “Enabled” checkbox corresponding to each of the other scripts you’re using. The only one which should stay enabled is the “Facebook-Events-To-Top”. Then, you should just press OK and refresh the Facebook page.

After all the tests have been made you can re-enable your other scripts.

]]> This is a tool I’ve made two years ago to solve a problem a friend of mine had. He had at his work a bunch of Word and Excel files created in different computers and wanted to cleanup their properties so they didn’t show the configured Author/Title/Subject/etc. tags.

Office_Document_Property_Resetter_DOC_Prop_1

This would have been a simple problem to solve if there were a few files… They could be cleaned up manually…

Office_Document_Property_Resetter_Word_Menu

Office_Document_Property_Resetter_Word_Prop_1

But there were lots of them!

So… I made this tool :)

Office_Document_Property_Resetter_Main

It’s very easy to use… You just choose the folder where the files are located (it recurses subdirectories) and press Start…

Office_Document_Property_Resetter_Start

You won’t be able to cancel it while working… So, if there are lots of files to process, it could take some time to complete… I recommend running it when you don’t need to use the computer for a while…

Office_Document_Property_Resetter_Working

Once finished, it will show you the summary of what it has done…

Office_Document_Property_Resetter_Finish

In this case there were only two files…

Office_Document_Property_Resetter_Folder

And that’s all… Everything will be cleaned up…

Office_Document_Property_Resetter_DOC_Prop_1b

  • C:\Program Files\Microsoft Office\Office11\excel.exe

Those paths are from an Office 2003 installation… I recommend using those files instead of the ones from an Office 2007 (or later) installation since the latter would make the program unusable on computers having the earlier version.

Instead of copying the files, you could locate the following piece of code in the file “Office Document Property ResetterDlg.h“:

//#import "C:\Program Files\Common Files\Microsoft Shared\Office11\MSO.DLL"
#import "Office 2003\MSO.DLL" \
	no_namespace \
	rename("SearchPath", "SearchPathMSO") \
	rename("RGB", "RGBMSO")

//#import "C:\Program Files\Common Files\Microsoft Shared\VBA\VBA6\VBE6EXT.OLB"
#import "Office 2003\VBE6EXT.OLB" \
	no_namespace

//#import "C:\Program Files\Microsoft Office\Office11\MSWord.olb"
#import "Office 2003\MSWord.olb" \
	rename("FindText","FindTextWord")  \
	rename("ReplaceText","ReplaceTextWord")  \
	rename("ExitWindows","ExitWindowsWord")  \
	rename("RGB","RGBWord")  \
	no_dual_interfaces

//#import "C:\Program Files\Microsoft Office\Office11\excel.exe"
#import "Office 2003\excel.exe" \
	exclude("IFont")	\
	exclude("IPicture")	\
	rename("ReplaceText","ReplaceTextXLS")  \
	rename("RGB","RGBXLS")  \
	rename("DialogBox","DialogBoxXLS")  \
	rename("CopyFile","CopyFileXLS")  \
	no_dual_interfaces

And replace it with (notice the addition of the trailing slash):

#import "C:\Program Files\Common Files\Microsoft Shared\Office11\MSO.DLL" \
	no_namespace \
	rename("SearchPath", "SearchPathMSO") \
	rename("RGB", "RGBMSO")

#import "C:\Program Files\Common Files\Microsoft Shared\VBA\VBA6\VBE6EXT.OLB" \
	no_namespace

#import "C:\Program Files\Microsoft Office\Office11\MSWord.olb" \
	rename("FindText","FindTextWord")  \
	rename("ReplaceText","ReplaceTextWord")  \
	rename("ExitWindows","ExitWindowsWord")  \
	rename("RGB","RGBWord")  \
	no_dual_interfaces

#import "C:\Program Files\Microsoft Office\Office11\excel.exe" \
	exclude("IFont")	\
	exclude("IPicture")	\
	rename("ReplaceText","ReplaceTextXLS")  \
	rename("RGB","RGBXLS")  \
	rename("DialogBox","DialogBoxXLS")  \
	rename("CopyFile","CopyFileXLS")  \
	no_dual_interfaces

That will make the compiler look for the files at their actual location… (Do not forget to update the paths if you have installed Office in a different path)

That’s all… Enjoy it!

]]> Every C++ programmer knows that the standard library has a string class. But, while learning, it’s a good idea to know how to develop your own string class.

That’s why I made the String class. It’s not intended for professional projects (for them, you should use the standard library’s string), but as help to learn C++.

class String
{
	char *m_pszString;	//Allocated buffer
	int m_nAllocated;	//Allocated length

public:
	//Construction and destruction
	String() { /* ... */ }
	~String() { /* ... */ }

	//Copy constructors
	String(const char *pszString) { /* ... */ }
	String(const String& rsString) { /* ... */ }

	//Operators (assignment)
	String& operator=(const char *pszString);
	String& operator=(const String& rsString) { /* ... */ }

	//Operators (concatenation)
	String& operator+=(const char *pszString);
	String& operator+=(String& rsString) { /* ... */ }
	String operator+(String rsString);

	//Operators (comparison)
	bool operator<(String sString) { /* ... */ }
	bool operator<=(String sString) { /* ... */ }

	bool operator>(String sString) { /* ... */ }
	bool operator>=(String sString) { /* ... */ }

	bool operator==(String sString) { /* ... */ }
	bool operator!=(String sString) { /* ... */ }

	//Operations
	void Clear();
	String Lower() { /* ... */ }
	String Upper() { /* ... */ }

	//Information
	int Length() { /* ... */ }

	//Cast operators
	operator const char*() { /* ... */ }

protected:	//Helper functions
	/* ... */
};

//Output e input
std::ostream& operator<<(std::ostream& oStream, String& rsString);
std::istream& operator>>(std::istream& iStream, String& rsString);

This is a sample project made to explain the String class usage.

#include <iostream>
	using std::cout;
	using std::cin;
	using std::endl;
#include "String.h"

using namespace std;

int main(int argc, char *argv[])
{
	cout << "String sample project" << endl;
	cout << "---------------------" << endl << endl;

	String a("This"), b("is"), c("a"), d("test");
	String e = a + " " + b + " " + c + " " + d;

	cout << "String parts:" << endl;
	cout << '\t' << a << endl;
	cout << '\t' << b << endl;
	cout << '\t' << c << endl;
	cout << '\t' << d << endl << endl;

	cout << "Concatenated with spaces:" << endl;
	cout << '\t' << e << endl << endl;

	String f, g;

	cout << "Please input a string (empty to break): ";
	cin >> f;
	cout << "Please input other string (empty to break): ";
	cin >> g;

	cout << endl;

	cout << "1st string (" << f << ") is " << f.Length() << " chars long." << endl;
	cout << "2nd string (" << g << ") is " << g.Length() << " chars long." << endl;

	cout << endl;

	cout << "1st string in lowercase is " << f.Lower() << endl;
	cout << "1st string in uppercase is " << f.Upper() << endl << endl;

	cout << "2nd string in lowercase is " << g.Lower() << endl;
	cout << "2nd string in uppercase is " << g.Upper() << endl << endl;

	cout << "1 < 2\t=> " << (f<g?"true":"false") << endl;
	cout << "1 <= 2\t=> " << (f<=g?"true":"false") << endl;
	cout << "1 > 2\t=> " << (f>g?"true":"false") << endl;
	cout << "1 >= 2\t=> " << (f>=g?"true":"false") << endl;
	cout << "1 == 2\t=> " << (f==g?"true":"false") << endl;
	cout << "1 != 2\t=> " << (f!=g?"true":"false") << endl << endl;

	if (f == g)
		cout << "Strings are equal." << endl;
	else
		cout << "Strings are not equal." << endl;

	cout << endl;

	cout << "1+2\t=> " << f+g << endl;
	cout << "2+1\t=> " << g+f << endl;

	cout << endl;

    return 0;
}

And this is its output:

String sample project
---------------------

String parts:
        This
        is
        a
        test

Concatenated with spaces:
        This is a test

Please input a string (empty to break): Hello, string 1
Please input other string (empty to break): Phrase 2

1st string (Hello, string 1) is 15 chars long.
2nd string (Phrase 2) is 8 chars long.

1st string in lowercase is hello, string 1
1st string in uppercase is HELLO, STRING 1

2nd string in lowercase is phrase 2
2nd string in uppercase is PHRASE 2

1 < 2   => false
1 <= 2  => false
1 > 2   => true
1 >= 2  => true
1 == 2  => false
1 != 2  => true

Strings are not equal.

1+2     => Hello, string 1Phrase 2
2+1     => Phrase 2Hello, string 1

The code completely is portable.

It’s been developed, compiled and tested using wxDev-C++ for Windows with the MinGW compiler (included in the bundle).

]]> This library is the C++ sequel to the cMemDbg.

Just as the cMemDbg, it is a very easy to use library which can help you to detect and track memory leaks.

Its usage is very similar to the cMemDbg, but with support for the C++ operators (new, new[], delete and delete[]).

There are lots of solutions for this on the net, but this one has the particularity of being really simple to implement.

>INFO  PROBLEM: Memory leak found (36 bytes)

You just have to add the following include to your main include file (a file that gets included by each file of your project) or, in case you don’t have one, to each file that calls any memory allocation function (malloc, realloc, calloc, free, new, new[], delete or delete[]).

This is the line:

#include "cMemDbg.h"

There are two extra cautions you have to take into account:
1- Include it after the standard headers (stdio.h, stdlib.h, malloc.h, etc.).
2- Never call the delete (or delete[]) operator without knowing if its argument is NULL. So: “delete a;” should become “if (a) delete a;”. Otherwise, the library may show incorrect messages.

That’s all… Expecting more? Well, there is a final step… You have to make this call just before you exit your program so you can get the detailed conclusions:

PrintMemoryLeakInfo();

By default, the library output will go to stdout (normally the console screen). If you want to redirect it to a file, you can call the InitCPPMemDbg() function. This is its prototype:

void InitCPPMemDbg(const char *pszOutputPath = NULL);

Other option, to simplify, is to create a global object of the “cppMemDbg” type at the beginning of the global declarations. You can pass a file path to the constructor to redirect the output. It will call InitCPPMemDbg (to setup the redirect) at construction and PrintMemoryLeakInfo() at destruction.

Simply like this:

cppMemDbg cDbg;

Or, with redirection:

cppMemDbg cDbg("mylocalfile.txt");

Easy, not?

That was all… Really.

The code completely is portable.

GNU GPL v3 cppMemDbg is licensed under the GNU GPL v3 (attached)…

Now, before going to more “expert” features, I’ll leave here the link to download the library for the ones who don’t wish to keep reading:

Now let’s continue…

The library comes with three configurable settings (available in cppMemDbg.cpp):

  • PRINT_OPERATIONS: If set to 1, it will print to the configured output (stdout by default) each memory alloc operation done in the program (allocation or free). Otherwise, the library will just print problems and notifications and the final dump. [Default value = 1]
  • MAX_ALLOC: Internal library memory stack length (in elements). It is the max amount of allocations that can be tracked without being freed. You can increase this value at will if needed. In fact, if it is needed, the library will print a message saying: “INTERNAL_ERROR: Allocation stack overflow, please increase MAX_ALLOC”. [Default value = 256]
  • g_fFile: FILE* to print the library generated notifications to. [Default value = stdout]
  • MAX_DELETE_STACK: Internal library delete nesting stack array length (in elements). It is the max amount of deletes that can be nested. You can increase this value at will if needed. In fact, if it is needed, the library will print a message saying: “INTERNAL_ERROR: Delete stack overflow, please increase MAX_DELETE_STACK”. [Default value = 16]

Finally, there are two more functions you could use wherever needed:

  • PrintTotalAllocatedMemory(): Prints the accumulative amount of memory allocated at the moment of the call.
  • PrintMemoryReservedByCMemDbgLibrary(): Prints the amount of memory reserved by the library (defined at compilation time by the MAX_ALLOC constant).

That’s all… I said it was easy to use.

Anyway, if after reading the cppMemDbg.h file’s comments, you have any questions, comments or suggestions, please feel free to contact me.

Here is the Attendance Control project modified to test it for memory leaks and allocation/deallocation problems with the cppMemDbg library:

The code is portable between Linux and Windows (I’ve tested it myself on both platforms and it worked seamlessly).

It’s been developed, compiled and tested using wxDev-C++ for Windows with the MinGW compiler (included in the bundle). In Linux, it was compiled using the GNU GCC compiler.

It is configured to send the output to the “TestMemDbg.txt” file in the working directory. This is the relevant piece of the Main.cpp file:

//...

#include "ControlDeAsistencia.h"
#include "BasicFunctions.h"
#include <fstream>

#include "cppMemDbg.h"

cppMemDbg cDbg("TestMemDbg.txt");

//...

And this is its successful output (the real output es tabbed to make it easier the analysis en a spreadsheet software):

>new[]  003D3F58  14  [String.cpp:59]
>new[]  003D2438  14  [String.cpp:59]

>delete[]  003D24F0  4  (String.cpp:59)  [String.h:41]
>delete  003D2490  40  (Lista.h:120)  [Lista.h:112]
>INFO  No memory leaks detected

]]> 4 o’clock in the morning… You’re going late to bed… Suddenly, you remember you had to send someone a message with some important information he should have at 9 o’clock…

Of course you don’t want to wake up at 9:00… If you send the message at this moment, you’ll probably wake him up if he didn’t power off the phone (he deserves it! :))…

So what can you do? This tool is the answer…

SMS_Scheduler_1

You can simply fill the message data (Recipient, Body and Desired Time) and press “Schedule”… (Multiple recipients are allowed separating them with semicolons)

SMS_Scheduler_2

Then, you can just go to sleep and wait for the message to be delivered at the time you wanted…

SMS_Scheduler_5

If you regret, you can always uncheck the box to cancel the message… (If not already sent, of course)

SMS_Scheduler_3

GNU GPL v3 SMS Scheduler is licensed under the GNU GPL v3 (attached)…

SMS_Scheduler_4

The installation package is targeted for Windows Mobile 5. I haven’t tested it on other versions, but, at least recompiling, should work on others…

It requires the .NET Compact Framework 2.0 installed on the Pocket PC… If you don’t have it, you can simply download the .NET Compact Framework 2.0 Service Pack 2 Redistributable and install it while having your Pocket PC connected to the computer with ActiveSync running (so it can get copied and installed into the device)…

The SMS Scheduller installer has to be run with the Pocket PC connected with ActiveSync running too…

Well, that’s all… Now, finally, the links…
