Remarks

This class provides a button that, when clicked, displays a Help topic by searching for the HelpContextID specified in the control.

To use, drop the class on a project or form or, from the Component Gallery Item Shortcut Menu, select Add to Form. When you add the class to a form, Visual FoxPro places a button on your form. You need to provide the appropriate value to replace the default value of HelpContextID. When you drop the class on a project, you can choose between adding the class or creating a subclass.
