KB: Hiding user interface at scanning.

User interface of scanner can be hidden only if you use TWAIN driver for your scanner.
WIA driver does not allow to hide (disable) user interface - it's limitation of WIA drivers when they are used via TWAIN interface.

Here is a code snippet for VB.NET that shows how to acquire images without UI:

  Try
    VSTwain1.StartDevice()
    If VSTwain1.SelectSource() Then
      VSTwain1.ShowUI = False
      VSTwain1.DisableAfterAcquire = True
      VSTwain1.OpenDataSource()
      VSTwain1.UnitOfMeasure = Vintasoft.Twain.UnitOfMeasure.Inches
      VSTwain1.PixelType = Vintasoft.Twain.PixelType.RGB
      VSTwain1.Acquire()
    End If
  Catch ex As TwainException
    MsgBox(ex.Message)
  End Try
