Requirements and Dependencies

Developers who want to add entries to the standard context menus in Internet Explorer must be familiar with the registry. Developers should also be familiar with context menus. For more information about context menus, see the Windows Shell API documentation in the Platform Software Development Kit (SDK).

The implementation described here is valid for Internet Explorer 4.0 or later. This feature is not available in earlier versions of Internet Explorer.

Implementation Steps

The following steps are required to add an entry into the standard context menus in Internet Explorer.

1. Create a new key, using the text you want displayed in the context menu as the name, under:

   HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\MenuExt

   The result should look like:

   HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\MenuExt\<Menu Text>

   <Menu Text> should be replaced with the text that you want displayed in the context menu. The name can include an ampersand (&) character, which will cause the character that follows to be underlined and used as a shortcut key.

2. Set the default value of the key to the URL of the page that contains the script you want the context menu entry to execute. This script can obtain the parent window object, the screen where the context menu item was executed, from the menuArguments property of the external object.
3. Optional. Create a binary value, Contexts, under:

   HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\MenuExt\<Menu Text>

   The result should look like:

   HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\MenuExt\<Menu Text>\Contexts

   Set the value of Contexts to indicate which contexts your entry should appear in the standard context menu by using a bit mask consisting of the logical OR of the following values:

   Context	Value
   Default	0x1
   Images	0x2
   Controls	0x4
   Tables	0x8
   Text selection	0x10
   Anchor	0x20

   For example, if you want your context menu entry to appear in the default context menu and when the context is a text selection, set the value of Contexts to 0x11.

4. Optional. Create a DWORD value, Flags, under:

   HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\MenuExt\<Menu Text>

   The result should look like:

   HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\MenuExt\<Menu Text>\Flags

   Set the value of Flags to 0x1 to make the script run just as if it had been called through the showModalDialog method. Unlike the showModalDialog method, the script can access the window object of the parent window from the menuArguments property of the external object.

Strings stored inside a resource can be referenced by providing the path to the resource and reference identification in the format "path, resource_id". For example, if you wanted to use string resource 123 in Example.dll, you would use "Example.dll, 123".
