The ACM_PLAY message plays an AVI clip in an animation control. The control plays the clip in the background while the thread continues executing. You can send this message explicitly or by using the Animate_Play macro.

wParam = (WPARAM) (UINT) cRepeat;
lParam = (LPARAM) MAKELONG(wFrom, wTo);
Parameters
cRepeat
Number of times to replay the AVI clip. A value of - 1 means replay the clip indefinitely.
wFrom
Zero-based index of the frame where playing begins. The value must be less than 65,536. A value of zero means begin with the first frame in the AVI clip.
wTo
Zero-based index of the frame where playing ends. The value must be less than 65,536. A value of - 1 means end with the last frame in the AVI clip.

If the operation succeeds, the return value is a nonzero value.
