    Hi all
    Iam wrapping twain32.dll via VB.NET 2003
    I need help how to calculated DPI that supported by scanner device.
    I used Canoscan N650u
    I have already get value from YRESOLUTION and XRESOLUTION, and get XRESOLUTION value below :
    Default : 75
    MaxValue:9600
    MinValue:25

    and YRESOLUTION value below:
    Default : 75
    MaxValue:9600
    MinValue:25

    but on CanoScan application DPI only supported between 75DPI to 1200DPI. So i need help how to list DPI that supported by scanner device.

    Thanks
