Hello,

I am trying to retrieve the serial number of my scanner.
My scanner is capable of providing the serial number.

I have tried the following code but i am not getting the result i am needing.

Im coding in C#

Quote:
strSerialNumber = _twainSession.GetCapability(TwainCapabilityType.SerialNumber, TwainGetCapabilityMode.GetDefault).ToString();

System.Windows.MessageBox.Show(strSerialNumber);


I am getting Leadtools.Twain.TwainCapability as the result in my messagebox.

Hello,

You need to know the type of capability it is and then access the value of that like so:

Code:
    var cap = _twainSession.GetCapability(TwainCapabilityType.SerialNumber, TwainGetCapabilityMode.GetDefault);
         var strSerialNumber = cap.OneValueCapability.Value.ToString();
         MessageBox.Show(strSerialNumber);
