i try to write a tetrisclone... everytime i run this programm it doesnt respond (ctrl-alt-del), it's because of the timer i think because without it, it runs fine(but to fast for checking the pressed keys), so what did i wrong? #include // Header File For Windows #include // Header File For Standard Input/Output #include // Header File For The OpenGL32 Library #include // Header File For The GLu32 Library #include // Header File For The Glaux Library #include #include // Header File For Variable Argument Routines HDC hDC=NULL;
