Пример

// This example creates a secondary thread that implements
// the methods of CAnimateCtrl. The procedure of the thread
// is MyClipThreadProc and the thread was created with the
// code AfxBeginThread( MyClipThreadProc, (LPVOID) pParentWnd).
// The example code creates and initializes an animation control,
// then proceeds to pump messages from the queue until one the 
// private messages WM_STOPCLIP, WM_PLAYCLIP, WM_SHOWFIRSTFRAME or 
// WM_SHOWLASTFRAME is received. The appropriate action is done for
// these messages. The thread ends when the WM_STOPCLIP is received.
// NOTE: the thread parameter, pParam, is a pointer to a CWnd object
// that will be the parent of the animation control. 

#define WM_STOPCLIP               WM_USER+1
#define WM_PLAYCLIP               WM_USER+2

#define WM_SHOWLASTFRAME         WM_USER+4
