Hello
Is there a way to stop the scanners own dialog popping up ? i.e. with the final Scan button and colour choice etc.

It can be done with TWAIN but can't see how with WIA - there doesn't seem to be an equivalent to -

ImageEnView1.IO.TWainParams.ProgressIndicators := False;

Or a way to force Grayscale. The popup mentioned always defaults to Colour.

Thanks

Andy
