NotSupport in Wince

[dadahacker]

I am going to make a videoPlayer with directshow ,c#,wince 6.0,but this is a problem ,It will happen to show " NotSupportException ",and many place will happen ,such as "OnMouseDown(e),DoubleClick()",and it don't reference to ang CF system function ,I notice that ,if not to use directshow ,it will be ok ,so I will think directshow will effect that message event ?
