expression.WhatsThisButton
expression Required. An expression that returns one of the objects in the Applies To list.
Remarks
The WhatsThisButton property uses the following values:
Setting | Visual Basic | Description |
---|---|---|
Yes | True | A What's This button appears on the title bar. |
No | False | (Default) A What's This button doesn't appear on the title bar. |
You can set the WhatsThisButton property by using the form's property sheet, a macro, or Visual Basic.
This property can be set only in form Design view.
You can't display the What's This button on the title bar of a form unless the MinMaxButtons property is set to None.
Clicking the What's This button on the title bar of a form causes the question-mark mouse pointer to appear. With the question-mark pointer, you can click any control to access its custom Help topic specified by the control's HelpContextID property. If the control doesn't have a custom Help topic, the form's custom Help topic is displayed. If neither the form or the control has a custom Help topic, Microsoft Access Help is displayed.
Example
The following example places a What's This button on the title bar of the "Switchboard" form. The form must be in form Design view, or else a run-time error will occur.
Forms.Item("Switchboard").MinMaxButtons = 0
Forms.Item("Switchboard").WhatsThisButton = True
