hi, I'm italian and so I'm not so good in english...

I use your eval tools to see if it is good for my future projects and I use visual studio .net with vb.net language.  I'm goingo to record video from my dv camera and I wanto to control zoom. When I tryed to ccess to the object ltmmCaptureCtrl.CameraControl it is ever set to "nothing".

So I ask you how to access to this object and how to control the zoom of my camera (if it is possible)..

Thank's in advance

Not all devices expose this interface.  Therefore, this property
may be updated with NULL.  Your camera driver probably does not export this interface.

Hi Mario,

Unfortunately, I do not know any specific devices that export this interface.

Yes, I was referring to the driver of your device.  It probably
does not export this interface.  If you want to be sure, you might want to contact the manufacturer.
