Hi All,
why a DirectX application fails in Remote Desktop Mode?

Probably

because DirectX directly talks to the video hardware rather than going

through GDI and/or video driver, thus not allowing the desktop image to

be reproduced in the remote desktop session.

I'll move this thread to the DirectX forum for a better answer...

I suspect that remote desktop, like virtual PC, does not emulate a powerful enough graphics card to run your application.

However, I though that a windowed DirectX app should run just very very slowly as it will have to transfer the entire windows content as bitmap every time. FullScreen I doubt you will see anything.

Hi,
another possibility for DirectX failing in remote desktop is when you don't handle the loss of device. Check if you're handling this right. Tip: if this is the case then the error should also happen in your computer when, for example, the screen saver becomes active.

Because DirectX wasn't designed to work in a Remote Desktop scenario.
