Animation Control Styles

This section lists the window styles used with animation controls.

Constant Description
ACS_AUTOPLAY
Starts playing the animation as soon as the AVI clip is opened.
ACS_CENTER
Centers the animation in the animation control's window.
ACS_TIMER
By default, the control creates a thread to play the AVI clip. If you set this flag, the control plays the clip without creating a thread; internally the control uses a Win32 timer to synchronize playback.
Comctl32.dll version 6 and later: This style is not supported. By default, the control plays the AVI clip without creating a thread.
Note: Comctl32.dll version 6 is not redistributable. To use Comctl32.dll version 6, specify it in a manifest. For more information on manifests, see Enabling Visual Styles.
ACS_TRANSPARENT
Allows you to match an animation's background color to that of the underlying window, creating a "transparent" background. The parent of the animation control must not have the WS_CLIPCHILDREN style (see Window Styles). The control sends a WM_CTLCOLORSTATIC message to its parent. Use SetBkColor to set the background color for the device context to an appropriate value. The control interprets the upper-left pixel of the first frame as the animation's default background color. It will remap all pixels with that color to the value you supplied in response to WM_CTLCOLORSTATIC.
