Thread: How DO I Get Rid Of Warnings?

Code:

int WINAPI WinMain(HINSTANCE hInstance,
                   HINSTANCE hPrevInstance,
                   LPSTR     lpCmdLine,
                   int       nCmdShow)
{
    // declare variables
	MSG msg;

	// register the class
	MyRegisterClass(hInstance);

    // initialize application 
    //note--got rid of initinstance
    HWND hWnd;

    //create a new window
    hWnd = CreateWindow(
       APPTITLE,              //window class
       APPTITLE,              //title bar
       WS_EX_TOPMOST | WS_VISIBLE | WS_POPUP,   //window style
       CW_USEDEFAULT,         //x position of window
       CW_USEDEFAULT,         //y position of window
       SCREEN_WIDTH,                   //width of the window
       SCREEN_HEIGHT,                   //height of the window
       NULL,                  //parent window
       NULL,                  //menu
       hInstance,             //application instance
       NULL);                 //window parameters

    //was there an error creating the window?
    if (!hWnd)
      return FALSE;

    //display the window
    ShowWindow(hWnd, nCmdShow);
    UpdateWindow(hWnd);
	
	//initialize the game
    if (!Game_Init(hWnd))
        return 0;


    // main message loop
    int done = 0;
	while (!done)
    {
        if (PeekMessage(&msg, NULL, 0, 0, PM_REMOVE)) 
	    {
            //look for quit message
            if (msg.message == WM_QUIT)
            {
                MessageBox(hWnd, "Received WM_QUIT message", "WinMain", MB_OK);
                done = 1;
            }

            //decode and pass messages on to WndProc
		    TranslateMessage(&msg);
		    DispatchMessage(&msg);
	    }
        else
            //process game loop (else prevents running after window is closed)
            Game_Run(hWnd);
    }

	return msg.wParam;
}

With the line in bold I get a warning conversion of wparam to int possible loss of data, and with the random number seed: srand(time(NULL)); I get the warning time_t to unsigned int possible loss of Data. This is code from my book on Direct_X and I would like to know why I get these errors so I can start making the full program.

WOW, it worked. Cheers. Yeah, the book was in C b ut I only know C++ but a lot of the code looked very familiar so I bought it.

Casting message.wParam is an unfortunate necessity, but casting the standard srand(time()) idiom might not be a good idea. Search this board for the two functions, especially for posts by Prelude.
