Yes, with a different failure; can't recall exactly. I'll check again tomorrow.

Tested this again today. Using TransferMode := ttmMemory, ScanTest.bmp is the result using the "standalone" DLL, and ScanTestA.bmp is the result using the "RDS" DLL.

 

 

ScanTest.bmp

ScanTestA.bmp

Ah. But it does not not crap out 

There is definitely some alignment problem.

 

You say "RDS" DLL. How is that DLL different?

Is there something done with the calls?

Could you share the code?

 

Maybe if that problem is fixed, the other method with ttmNative is fixed automatically too.

The difference is it is loaded by RDS.

I could put together code that just replicates the problem, if you're able to help with it

If you can put together an example and the virtual channels work the same on RDP on win10, I can take a look.

 

I take it this should do the same as TSScan and RemoteDesktopTwain but then directly from your own local utility program.

I've finally managed to put together a test case, which is here: https://github.com/DelphiWorlds/MiscStuff/blob/master/Test/RDSTwainTestCase.zip

Bumping this in case anyone else might be able to contribute, i.e. we're still having the same problem.  Test case is still in the same location, i.e:
