Dear,
I have a CCD (24C1.35 www.videologyinc.com) that i can see how USB Camera or TWAIN.
Now, I wish I could capture a new image without operator intervention and without use the acquisition dialog. It's possible using twain or wia?

Thanks,
David

Hello,
sorry for my bad English, too!

Seeing the CCD as a USB camera (having WDM drivers), you could capture using DirectShow interface. Look at DirectShow samples. In this case you can see the living preview and capture a shot.

Seeing the CCD as a TWain device, just set IO.TwainParams.VisibleDialog=false to hide the acquire device dialog. Look at Twain sample. Using Twain and VisibleDialog you will not see the living "preview", but only the captured shot.
