Re: TWAIN: Main Window scaled after Close/Unload Source

Thanks Hugo!

That's seems to be the issue indeed. Seems that we got stuck supporting legacy Windows versions so we're lacking some proper handling for that matter.

Cheers!

TWAIN: Main Window scaled after Close/Unload Source

Preface: This issue was first observed using GdPicture with C++ COM interop and occurs after calling TwainGetState without calling any other GDP TWAIN function previously. On this occasion we monitored our Main Window for any WM_SIZE messages on its Procedure. Our window didn't received any thus we ...

Re: TWAIN + MICR on parallel

Sorry for the late response, Hugo! Both codes (TWAIN and MICR recon) works great when running independently. The issue only seems to occur when both are running in parallel: we have a DLL (C++ COM interface) that implements both the TWAIN and MICR code on a custom class. The TWAIN code runs on a thr...

TWAIN + MICR on parallel

Hi guys! Does anyone have implemented the Twain functionality in parallel with MICR (CMC7) recognition? We are using CMC7 recognition on a DLL module that implements MICR recognition from GdPicture alongside with engines. It combines the results for better performance. We've just implemented the twa...

Re: Strange exceptions on versions > 14.1.72

Thanks Hugo!

I'll gather a simpler version of the DLL with a demo project so I can ship it to you.

Best regards!

Strange exceptions on versions > 14.1.72

Hi guys, hope you are dong great. We've been using GdPicture at our company since version 5 or 9, integrating our C++ Win32 solutions by using COM Interop. Since GdPicture.NET version 10, we were able to create a C++ DLL that integrates with GdPicture.NET without MFC dependency, basically by using t...

C++ integration using CLR

https://docs.microsoft.com/en-us/cpp/dotnet/walkthrough-compiling-a-cpp-program-that-targets-the-clr-in-visual-studio?view=msvc-160 At our company we integrated GdPicture with C++ without using MFC and it was... quite tricky. We can't afford to have MFC dependencies and, despite that, we already mig...
