Problem finding issue

[dcoffey]

I realize this is not the correct forum, but I havnt had a response there so Ill repost.

I have GdPicture pro sdk (v5)

My scanning solution has worked for years now, but I am now having "crashes" when trying to use a Xerox 152
On my desk I have a Epson GT-S50, a Xerox 3125 and a Xerox 152 for testing. The Epson and the 3125 work perfectly.

When I plug up the Xerox 152, and I get to this line:
nImageID = Imaging1.TwainAcquireToGdPictureImage(Me.Handle)

The program crashes with a "program not responding"

In visual studio (2010) when I get to the line, I get a "vhost32.exe has stopped working" and crashes.

I have the line in a try/catch block but it doesn't catch, So I assumed it was a thread issue even though my app is not threaded. I created an unhandled thread event and it does not fire as I expected.

Here is the twain log.

Does anyone have any idea how I can find where my application is crashing and fix it? It obviously is something with th gdpicture imaging control but since I cant step into that Im just at a loss.

Any help greatly appreciated.

[dcoffey]

please disregard. I was able to fix the issue.

I assumed since this was a brand new in the box scanner the drivers would be relatively new. WRONG. The drivers was dated 2007 when I decided to check, latest version (2010) was on website.

Updating the drivers stopped the program from crashing.
