windowed Direct 3D

Can I use Direct 3D in a small window?
If yes, then can I have several different windows opened (all of them using direct 3d)?
Or must I use direct 3D in fullscreen mode?

Thanks..

Yes and yes, I believe! You just need to set up the window differently. (not the form, but the D3D Window)

Sas Is correct. You can have more than one window using DirectX, but if you create more than one D3DDevice, you will degrade performance. Look into the CreateSwapChain(or something like it, dont remember) function.

Ok. Thanks! :-)
