I'm a beginner to C++ and DirectX This is a great community ! ! ! This is my code :: // Include the Windows header file that’s needed for all Windows applications #include <windows.h> HINSTANCE hInst; // global handle to hold the application instance HWND wndHandle; // global variable to hold the window handle // forward declarations bool initWindow( HINSTANCE hInstance ); LRESULT CALLBACK WndProc( HWND, UINT, WPARAM, LPARAM ); // This is winmain, the main entry point for Windows applications int WINAPI WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow ) { "This is line 16 !!!!!!!!!!" // Initialize the window if ( !initWindow( hInstance ) ) return false; // main message loop: MSG msg; ZeroMemory( &msg, sizeof( msg ) ); while( msg.message!=WM_QUIT ) { // Check the message queue while (GetMessage(&msg, wndHandle, 0, 0) ) { TranslateMessage( &msg ); DispatchMessage( &msg ); } } return (int) msg.wParam; } This is the error ! ! ! d:\c++\example1\example1\winmain.cpp(16) : error C2731: 'WinMain' : function cannot be overloaded d:\c++\example1\example1\winmain.cpp(14) : see declaration of 'WinMain' Thanks for the Help ! ! !

Well, the error means like you have 2 or more winmains, or you have a different prototype than implentation..

From WinMain:

int WinMain(    HINSTANCE hInstance,    HINSTANCE hPrevInstance,    LPSTR lpCmdLine,    int nCmdShow);

Look at the way you have defined it: int WINAPI WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow ).

You need to use LPSTR instead of LPTSTR. To use LPTSTR, you should use the function GetCommandLine()
