Scanning from the ADF using WIA in C#

Sorry - need to fix these nested comments, getting a bit narrow down here.

'3' is FEED and FLAT, so no auto-detection capability. You can get the constant values from WiaDef.h (in the Platform SDK).

I'm out of ideas for now. I'll post back if I think of anything else. Please let me know if you figure this out so I can update the sample code if necessary.

It comes back as 3. I'm not certain which constant that is. I am on Win 7 64bit.

What is reported for the WIA_DPS_DOCUMENT_HANDLING_CAPABILITIES property (see comments above with MSDN link)?

Brother MFC-7340. I uninstalled and reinstsalled the device, double checked that the drivers were accurately installed and I get the same results.

What is the device that you're trying to work with? Have you tried checking to see if you have the latest drivers installed?

I took out the check for status and it throws a value out of expected range exception when it calls ShowTransfer. If I don't try to set the prop, it automatically goes to the flatbed. This is driving me insane.

It throws an exception that the value is not in range when the ShowTransfer method is called. If I comment out trying to change the prop, it automatically selects the flatbed.

No exception? It just hangs?

I know that some devices can detect if a document is in the ADF in which case you might not need to set the ADF option before scanning. If you comment this out does it get any further?

This code doesn't work for me. It stalls after checking the handling status. It acts like it is not setting the device handling to the feeder. Is there an issue with specific devices not being able to be set from WIA?

Thanks a lot Rob!
