HELPBUTTON property (Window)

If set to TRUE$ then the window displays a context-help button in its caption bar. When clicked the cursor changes to a question mark, and subsequently clicking on a control in the window will send it a HELP event.

This is a Boolean property. If set to TRUE then the context-help button is displayed, otherwise it is hidden.

This property implements the WS_EX_CONTEXTHELP Extended Window Style. It cannot be used if either the MINIMIZEBUTTON or MAXIMIZEBUTTON properties are set to TRUE$.
