Help: OLE Support for Help
This article describes the requirements for Help support in OLE visual editing applications.
For SHIFT+F1 support, some special coordination is required between OLE containers and in-place active servers. When the user chooses to activate SHIFT+F1 Help mode, both applications need to enter the mode. Whichever application first gets the message to enter the mode notifies the other application. Then either application is prepared to respond when the user clicks the mouse on an item for which he or she wants help. Likewise, when the user terminates Help mode, the application that gets the message first notifies the other application. Note that MFC automatically handles this notification process between the container and the in-place server.
Caution Neither the container nor the server can enter SHIFT+F1 help mode unless the other application also supports the mode.
For F1 help support, by contrast, whichever application gets the message when F1 is pressed handles the help request.
