Shutdown Method

Summary

Ends a TWAIN session.

Syntax

C++

public void Shutdown()

Public Sub Shutdown()

public: 
void Shutdown();

Remarks

A TWAIN session is started by calling the Startup method. For each call to the Startup method there must be a call to the Shutdown method. For more information, refer to Freeing the TWAIN Session.

Example

Imports Leadtools 
Imports Leadtools.Twain 
 
Public Sub ShutdownExample(ByVal parent As IntPtr) 
   Dim session As TwainSession = New TwainSession() 
   session.Startup(parent, "manufacturer", "productFamily", "version", "application", TwainStartupFlags.None) 
 
   Dim twCap As TwainCapability = New TwainCapability() 
 
   twCap.Information.Type = TwainCapabilityType.ImageTransferMechanism 
   twCap.Information.ContainerType = TwainContainerType.OneValue 
   twCap.OneValueCapability.ItemType = TwainItemType.Uint16 
   twCap.OneValueCapability.Value = TwainCapabilityValue.TransferMechanismNative 
 
   session.SetCapability(twCap, TwainSetCapabilityMode.Set) 
   session.Acquire(TwainUserInterfaceFlags.Show) 
   session.Shutdown() 
End Sub

using Leadtools; 
using Leadtools.Twain; 
 
public void ShutdownExample(IntPtr parent) 
{ 
   TwainSession session = new TwainSession(); 
   session.Startup(parent, "manufacturer", "productFamily", "version", "application", TwainStartupFlags.None); 
   TwainCapability twCap = new TwainCapability(); 
 
   twCap.Information.Type = TwainCapabilityType.ImageTransferMechanism; 
   twCap.Information.ContainerType = TwainContainerType.OneValue; 
   twCap.OneValueCapability.ItemType = TwainItemType.Uint16; 
   twCap.OneValueCapability.Value = TwainCapabilityValue.TransferMechanismNative; 
 
   session.SetCapability(twCap, TwainSetCapabilityMode.Set); 
   session.Acquire(TwainUserInterfaceFlags.Show); 
   session.Shutdown();
