Video player in vc++ (each frame being shown in a new window)

[hellSigma]

I am trying to show all the frames of a video sequence in the same window. But currently it is showing each frame in a different window. e.g. once it shows first frame, I need to close that window and then another window pops up and it shows next frame and then I need to close that one and then next window pops up...and so on.

i am using createwindow function to create a window and I associate HINSTANCE of a frame to HWND using CreateWindow function. If I do createwindow only once it just shows first frame in a window and once I close it nothing happens..

can anybody help me out with this???

Here is the part of code related to it:-

BOOL InitInstance(HINSTANCE hInstance, int nCmdShow)
{
   hInst = hInstance; // Store instance handle in our global variable

   hWnd = CreateWindow(szWindowClass, szTitle, WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, 0, CW_USEDEFAULT, 0, NULL, NULL, hInstance, NULL);


   if (!hWnd)
   {
      return FALSE;
   }


   ShowWindow(hWnd, nCmdShow);
   UpdateWindow(hWnd);

   return TRUE;
}

So when I call it in loop, each time it creates a new window for each frame. But if I call CreateWindow only once, then it doesn't update frame. If I am right its happening that way coz it doesn't associate new hInstance with window as hInstance is being updated with each frame.
Is there a way to associate/update hInstance to a hWnd without calling CreateWindow function? Or am I thinking in wrong direction? Can someone clarify please.
