Qt4 and TWAIN scanning

[^NyAw^]

Hi,
I'm trying to use Qt4 to scan images using TWAIN on Windows.
I have downloaded Qt TWAIN Package from http://www.cppfrance.com/codes/PACKA...AIN_46374.aspx and I'm modifing it to use Qt 4. The code was created by "Stephan Stapel" using Qt 3.

I've attached the Visual Studio Solution into the zip file to get any help. I've deleted "qtwaininterface" and "qtwainsubstitute".

The problem is that on "BOOL CTwain::ProcessMessage(MSG msg)" method, the line "if(GetRC() != TWRC_NOTDSEVENT)" always returns "TWRC_NOTDSEVENT" and so, the application never recives TWAIN messages.

I would like to port this to Qt 4 for everyone to want to use it and I will send the final version to the author "Stephan Stapel".

Thanks,
