WebCam driver

Question

Hi,
i'm developing an application that take pictures using a webcam. I'm using 'user32.dll' and 'avicap32.dll'. I have found a lot of examples but not any answer to my question. I'm using Logitech WebCam Fusion and is quiet good but i cant get it to take the best picture. When using

public const int WM_CAP_DLG_VIDEOFORMAT = WM_CAP_START + 41;

and

SendMessage(mCapHwnd, WM_CAP_DLG_VIDEOFORMAT, 0, 0);

the best pictures i can set is 704x576. I want to set it to 1290x960.

Anyone know how to fiks my problem?

please help

regards
Øystein Eriksen
