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:
Code: Select all
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
