| Platform SDK: Agent | 
| Part | Description | 
|---|---|
| Filename | A string expression specifying the path and filename of the Windows Help file. | 
If you've created a Windows Help file for your application and set the character's HelpFile property, Agent automatically calls Help when HelpModeOn is set to True and the user clicks the character or selects a command from its pop-up menu. If you specified a context number in the HelpContextID property of the selected command, Help displays a topic corresponding to the current Help context; otherwise it displays "No Help topic associated with this item."
This property applies only to your client application's use of the character; the setting does not affect other clients of the character or other characters of your client application.
