Word Developer Reference

Syntax

expression.SendWindowMessage(Message, wParam, IParam)

expression   Required. A variable that represents a Task object.

Parameters

Name Required/Optional Data Type Description
Message Required Long A hexidecimal number that corresponds to the message you want to send. If you have the Microsoft Platform Software Development Kit, you can look up the name of the message in the header files (Winuser.h, for example) to find the associated hexadecimal number (precede the hexidecimal value with &h).
wParam Required Long Parameters appropriate for the message you’re sending. For information about what these values represent, see the reference topic for that message in the documentation included with the Microsoft Platform Software Development Kit, available on MSDN. To retrieve the appropriate values, you may need to use the Spy tool (which comes with the kit).

Example

If Notepad is running, this example displays the About dialog box (in Notepad) by sending a WM_COMMAND message to Notepad. The SendWindowMessage method is used to send the WM_COMMAND message (111 is the hexidecimal value for WM_COMMAND), with the parameters 11 and 0. The Spy tool was used to determine the wParam and lParam values.

Visual Basic for Applications
