Dynamsoft TWAIN Products

Hi, I ran http://www.dynamsoft.com/demo/DWT5/onli ... anced.aspx using laptop Cam, but I got message:
Fail to set resolution.
Current source does not support the resolution you set.
I tried all resolutions, but it didn't work.

BTW, I use dell 1520 laptap. Hope repling.

The message indicates that the resolution you set is not supported by the driver of your camera. To solve the problem, please select a resolution supported by your camera, or you can try with the online demo at the following link to see if it works for you.
