Hi,
I am using Leadtools Raster Imaging Pro 15.
I am developing an windows application(Developed in C# & .Net 2005) in which i have to capture the images through web cam asynchronously.
In my application i am showing "Select Source" dialog by calling "TwainSession.SelectSource()" method by passing empty string.
The "Select Source" dialog will come on top of the application when i am calling "TwainSession.SelectSource()" in normal methods.
But the same "Select Source" dialog is coming behind the application when i am calling "TwainSession.SelectSource()" in asynchronous methods.
Would you please tell me how to make "Select Source" dialog to come on top of the application when i am calling "TwainSession.SelectSource()" in asynchronous methods?
Regds,
Deven.

Deven,
What is the difference between
the synchronous call and the Asynchronous call?
How are you doing both calls
exactly? Are you doing this in a separate thread, for example?
Can you put the scanning code
that doesn't work in a small working project (not your full application) and
send it to me in a ZIP or RAR file?
