How To Programmatically Change Printer Settings for Internet Explorer and WebBrowser Control by Using Visual Basic .NET


View products that this article applies to.

Summary

This article describes how to programmatically set the page margins, the header, and the footer for printing from Internet Explorer and the WebBrowser control.

Description of the Technique

Users can easily change Internet Explorer printer settings for the page margins, the header, and the footer through the Internet Explorer user interface. However, Internet Explorer and the WebBrowser control do not include methods to change these settings programmatically.

NOTE: You cannot use the ExecWB command to set the page margins, the header, or the footer. These values are stored in the registry.

If you need to programmatically change the printer settings for Internet Explorer or the WebBrowser control, you can only change the page margins, the header information, and the footer information. You cannot programmatically change other settings such as the page orientation or the default printer.

The following steps outline how Microsoft Internet Explorer accesses the printer settings:
  1. Internet Explorer tries to obtain the values from the following registry key:
    HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\PageSetup
  2. If the key in step 1 does not exist, Internet Explorer tries to create this key by copying the values from the following key:
    HKEY_LOCAL_MACHINE\Software\Microsoft\Internet Explorer\PageSetup
  3. If the key in step 2 does not exist, default values are provided.
NOTE: These registry values are system-wide and affect all instances of the WebBrowser control and Internet Explorer for the current user.

Visual Basic .NET Code to Modify Registry Key

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

This sample Visual Basic .NET code illustrates how to modify the required registry key:
Imports Microsoft.Win32
Imports System
'........................
Public Sub SetIEFooter()
        Dim strKey As String = "Software\Microsoft\Internet Explorer\PageSetup"
        Dim bolWritable As Boolean = True
        Dim strName As String = "footer"
        Dim oValue As Object = "My New Footer"
        Dim oKey As RegistryKey = Registry.CurrentUser.OpenSubKey(strKey, bolWritable)
        oKey.SetValue(strName, oValue)
        oKey.Close()

End Sub
				
NOTE: Your application must have read and write permissions for the registry key.
