Simple C++ List Class

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);

3D Pinball for Windows (Space Cadet) Cracker – How To Modify High Scores

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…

Convert Celsius to Fahrenheit Online

Since I’ve been having lots of visits in my wxWidgets version of the Celsius to Fahrenheit converter, I’ve decided to prepare an online javascript version which lets you easily make the conversion.

Move Facebook Events Box to Top

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 :)

How do I install it??

Office Document Property Resetter

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 :)

Simple C++ String Class

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) { /* ... */ }

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

	//Information

cppMemDbg – Easy to use C++ memory leak detection library

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.

SMS Scheduler

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…
