Hi, i'm trying to use opentwain with sceye scan, when i select the source and launch the Acquire dialog the application show the default scan dialog.

This dialog has a button (start scan), when press the button not receive the TransferReadyEvent.

I review the eventloop and always receive in the messagepump.PreFilterMessage the Enumerations.ReturnCode.NotDsEvent

 

Any idea?

This is in the sample and in my code.

Is a problem with Windows 7 x64 with the application compiled with the x86 flag, in windows XP runs correctly.

I've readed in the twain.org spec 2.1 that now the correct triplet is DG_CONTROL / DAT_CALLBACK / MSG_REGISTER_CALLBACK and MSG_INVOKE_CALLBACK, but the triplet DG_CONTROL /DAT_EVENT / MSG_PROCESSEVENT is supported in windows.

Any idea

 

Thanks in advance.

Best regards.
