Example

Imports Leadtools 
Imports Leadtools.Twain 
 
Public Sub TwainCapabilityExample(ByVal parent As IntPtr) 
   Dim twainSession As TwainSession = New TwainSession() 
   twainSession.Startup(parent, "manufacturer", "productFamily", "version", "application", TwainStartupFlags.None) 
   Dim capType As TwainCapabilityType() = twainSession.QuerySupportedCapabilities() 
   Dim i As Integer = 0
