Environment: XP SP2, VS2005, LeadTools .NET, SCSI KODAK DS 3500

I download the latest Twain Driver from kodak website for this scanner

This Code Crash/Hangs here m_TWainSession.LoadTemplateFile


If Leadtools.Twain.TwainSession.IsAvailable(Me) Then

m_TWainSession = New TwainSession()
m_TWainSession.Startup(Me, "Company", "suite", "1.0", "Image Tool")

AddHandler m_TWainSession.AcquirePage, AddressOf _twainSession_AcquirePage

m_TWainSession.SelectSource() 'SELECT DS 3500

m_TWainSession.LoadTemplateFile("c:\temp\test.tpl") 'HERE
If m_TWainSession.Acquire(TwainUserInterfaceFlags.Show) = Windows.Forms.DialogResult.OK Then
If m_Rasterimg IsNot Nothing Then
m_RasterCodecs.Save(m_Rasterimg, "c:\test.tif", RasterImageFormat.Tif, 0, 1, m_Rasterimg.PageCount, 1, CodecsSavePageMode.Overwrite)
End If
End If
m_TWainSession = Nothing
End If

If you put the following code in your project, what exactly do get in the output debug window?
Private Sub twnSession_SaveTemplate(ByVal sender As Object, ByVal e As Leadtools.Twain.TwainTemplateEventArgs) Handles twnSession.SaveTemplate
Debug.WriteLine("SaveTemplate: " + e.Capability.Information.Type.ToString())
End Sub

Private Sub twnSession_LoadTemplate(ByVal sender As Object, ByVal e As Leadtools.Twain.TwainTemplateEventArgs) Handles twnSession.LoadTemplate
Debug.WriteLine("LoadTemplate: " + e.Capability.Information.Type.ToString())
End Sub

Also, do you get any exception when you call the m_TWainSession.LoadTemplateFile method?
