     form and enter the text in the ToolTipText property of
     the control for which the tool tip is to be displayed.
    The SetToolTip() method of the ToolTip control is
     used to set the tool tip text for a control.

The HelpKeyword property under the Misc category of a
control is used to set the keyword for retrieving help from the
Help file specified in the HelpNamespace property.
