To define a help push button in a dialog box or dialog region, use the keyword help in the push button definition. A help push button has the following two special characteristics:
•It does not get the focus when you click on it.
•It does not invoke a response in ESL
Instead, ESL acts as though the user pressed the F1 key, and invokes the Windows Help system to display help for the ESL object that has the focus.
To create a message box that responds to the F1 key, use the ReplyToMessageWithHelp function in the Message DLL See the Reference Guide for more information.
