**HelpButton     SIGNED**

{{blk2blue.jpg|blk2blue.jpg}}

The **HelpButton **property contains the control number (usually represented by the control's Field Equate Label) of the window control that invokes Windows help for this ToolbarTarget object.

A value of zero (0) disables the toolbar help button.

**Implementation:**

The ToolbarTarget object uses this property to enable or disable the toolbar help button. The ToolbarTarget object "presses" the help (F1) key when the end user CLICKS the toolbar help button.
