Thread: Dev C++ Clear Screen

Indeed, but there is a port (conio.h / conio.c) in the include directory that makes the trick using console Win32 API functions.

What i am trying to do is get it to use clrscr(). I was looking at http://www.bloodshed.net/faq.html#6 and i found this:

I think that has something to do with it, but i can't figure out how to do that. Does anyone know what that means or how i can go about doing this. I was looking around here and saw that i can use system("cls"); to clear the screen but it says it isn't a very good way of doing it. I would rather do it the good way. Thanks for your help.

If you insist in clearing the screen, you can use the clrscr() from the conio port by Dev-C++ of the Borland C conio library.

There is a conio.h interface file in .../INCLUDE of Dev-C++, and a conio.c implementation file at the same location. Just add the latter to your project, and include <conio.h> where you need it.

Why in the world should the original poster have a .cpp file ? AFAIK, he is writing C-code (Gratuitous assumption based on the fact that he was posting to the C forum...)

To clear the console using windows API do this:

Code:

void cls(){
	CONSOLE_SCREEN_BUFFER_INFO conInfo;
	DWORD dummy;
	COORD home = { 0, 0 };
	HANDLE hConsoleOut;

	hConsoleOut = GetStdHandle( STD_OUTPUT_HANDLE );

	if(hConsoleOut == INVALID_HANDLE_VALUE) return;

	GetConsoleScreenBufferInfo( hConsoleOut , &conInfo );
	FillConsoleOutputCharacter( hConsoleOut ,' ', conInfo.dwSize.X * conInfo.dwSize.Y, home, &dummy );
	SetConsoleCursorPosition(hConsoleOut,home);
}

Looks like you could have just read the FAQ also.

Quzah.
