i get the error "option is not available" when trying to grab a still image, but only on certain Framegrabber (like the DFG/SV1)... on USB devices it works fine
Works fine with .Net component 2.1, not with 3.x

any idea?

Hi Chris,

Please call "LiveStart" before you call "memorysnapImage" and after this call "livestop".
I think the problem is that there are some parameters set in the properties of the component. Thus please start your project with no video capture device selected. Then rebuild your project. I guess the problem with then be away.

I did "LiveStart"...
I tried with a complete new control on the form... no luck

i can send you a demo app VS 2005 where the problem occurs, of course you need a machine with a DFG/SV1 card...

Hi Chris,

Yes, its no problem. Did you check, whether livecapturecontinous has been set to false?
