    Twain Scanning in VB .Net

    Hello,

    I am trying to perform Twain scanning using the twain_32.dll, but no luck. Whatever solutions I have got call the dll GUI.

    I want to perform scanning by passing custom settings to the scanner for every scan. For eg. In duplex I want to scan the Front side in color & Back side in Grayscale.
    OR
    Scan every Alternate page as Color and B/W

    The combination can be anything. I've tried & and succeeded using WIA but it limited me to a certain extent.
    Can anyone help me with how to proceed using TWAIN and without displaying the GUI.
    I am open to options where a communication to Twain Connection Manager is established & commands are passed.

    Thank you in advance

    This pattern in common to all great programmers I know: they're not experts in something as much as experts in becoming experts in something.

    The best programming advice I ever got was to spend my entire career becoming educable. And I suggest you do the same.
