    Smile MOVEMOUSE event!

    Env: Win32 (Visual C++)

    I'm using WM_MOUSEMOVE to change a button (using STATIC with SS_BITMAP) so that when the mouse is hovering at the button it change from Default.bmp to Hover.bmp. I manage to compile and the program is running, but the button doesn't change sometime.

    Any solution and hel, will be great. Thanks.

    P.S Sorry for my bad english
    Code:
    LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
    {
    	flashMWindow.cbSize = sizeof(flashMWindow);
    	flashMWindow.dwFlags = FLASHW_ALL;
    	flashMWindow.dwTimeout = 250;
    	flashMWindow.hwnd = hWnd;
    	flashMWindow.uCount = 4;	
    
    	static BOOL  Click, BtnConnectClick, BtnConnectHover, BtnConnectChange;

    Re: MOVEMOUSE event!

    You are painting on the child window (i.e., the static window) from the WM_PAINT of the parent. That's usually poor practice; the child window should do all of its own painting, in response to WM_PAINT messages sent to the child.

    In addition, you are calling BeginPaint and EndPaint twice. They should be called only once in any one WM_PAINT procedure.
