PDF-XChange hangs while twain scanning

Post by alex-5215 » Fri Jul 05, 2019 10:40 am

Hello. I am a twain datasource developer and I have a problem with PDF-XChange Editor software.
The XChange Editor twain scanning hangs with this scenario:
- app request DG_CONTROL / DAT_USERINTERFACE / MSG_ENABLEDS
- datasource answer : TWRC_SUCCESS
- datasource send message from separate thread DG_CONTROL /DAT_NULL /MSG_XFERREADY
- app answer TWRC_FAILED and stucked

Working scenario:
- app request DG_CONTROL / DAT_USERINTERFACE / MSG_ENABLEDS
- datasource send message from enableds call thread DG_CONTROL /DAT_NULL /MSG_XFERREADY
- app answer : TWRC_SUCCESS
- datasource end enableds call with TWRC_SUCCESS.

According to the twain-2.4-Specification.pdf, page 13-31, first scenario seems correct.
I can provide additional info if needed.

Best regards,
Alexander.

Hello Alexander,
A few questions please:
What is the process name this interaction runs in? Is it PDFXEdit.exe or PDFXHost*.exe?
Do you run 64-bit or 32-bit PDF-X Editor?
Do you provide your data source module of the same bitness as the PDF-X Editor is?

Process name is PDFXHost32.exe.
I run 64-bit PDF-X Editor on Win 7 x64.
My data source is 32-bit only.

Thank you Alex.
We have started investigation on this issue.

Does portable PDF-XChange Editor work with your datasource?
