is there a directx forum i should have posted this in?

Okay, I want to put in transitions but I'm not sure where to start. i.e. I wanted to use the Dirextx transitions I can't seem to even get them into the program. If you can't tell I am very new to using the environment. I was under the impression that something like this "DXImageTransfo rm.Microsoft.Wh eel(duration=1, spokes=20)" would work in c# but I can't seem to find the reference to add to use these transforms on the pictures.
...

I need to create a screensaver that detects the resolution of one or 2 monitors and then selects the correct picture for that resolution and then uses transitions to make it like a slideshow with only one picture.

I didn't have a problem getting the screenresolutio n detection working. I just can't seem to figure out how to get the transitions started/working.

Thanks in advance.
