    Ok, I’ve found a twain documentation for different tests they have done.

    http://nt.twain.org/docs/TWTestRecAddendum.PDF

    So if you search for DAT_EXTIMAGEINFO you’ll find the section with the steps to do. But at one part it says to:

    ‘WaitForTransferReady*’ (it’s on page 12)

    How do you wait for it to be done with a certain state? (like joining a thread?).

    I haven’t even tested to see if the scanner supports the extended image info capability, but still want to know how to do this.

    Thanks a lot,

    Justin

    p.s.

    I’m writing this in vb.net, I found a starter project and I’m just running with it.
