What platform are you targeting? I assume Pocket PC, in which case there is
no built in support for AVI or MPEG video. You could use a 3rd party player
which you can launch using ShellExecuteEx or CreateProcess P/Invokes (See
OpenNETCF WinAPI for implementations - www.opennetcf.org/winapi.asp). I'm
not aware of any third party controls which you can drop into your forms to
do this though. It is possible to use the Windows Media Player ActiveX
control in conjunction with odysseys cfcom product however this will only
play windows media videos and the ActiveX control is only available for
Pocket PC 2002 (not Pocket PC 2003) devices.
