WIA Problem

[lorenzo]

I'm trying to catch a scanner image with a custom WIA Interface.
I can take the bitmap stream of the scanned image, but I'm trying to
get the image directly from paint (from scanner...) passing the handle
that I receive from the function DeviceDialog, but it don't work.

The second problem:
I set the scanner parameter WIA_DPS_PREVIEW to WIA_PREVIEW_SCAN , but
the BandedDataCallback function don't receive the message
IT_MSG_FILE_PREVIEW_DATA, but receive the message IT_MSG_DATA.


Have you any idea ?


Thanks
