Settings

The settings for boolean are:

Setting	Description

False	(Default) The application uses the F1 key to start Windows Help and load the topic identified by the HelpContextID property.

Remarks

There are three access techniques for providing What's This Help in an application. The WhatsThisHelp property must be set to True for any of these techniques to work.

Providing a What's This button in the title bar of the form using the WhatsThisButton property. The mouse pointer changes into the What's This state (arrow with question mark). The topic displayed is identified by the WhatsThisHelpID property of the control clicked by the user.
Invoking the WhatsThisMode method of a form. This produces the same behavior as clicking the What's This button without using a button. For example, you can invoke this method from a command on a menu in the menu bar of your application.
Invoking the ShowWhatsThis method for a particular control. The topic displayed is identified by the WhatsThisHelpID property of the control.
