Add Right-Click Functionality

By default, the right-click functionality needed for What's This? Help is not available in VB. Selecting a menu command from a context menu created for the button lets you display the What's This? Help topic when the user right-clicks on a command button. First, set the WhatsThisHelp property of the form to True. Place a CommandButton control on the form. Using the Menu Editor, create a menu with a top-level invisible item named mnuBtnContextMenu, and a submenu named mnuBtnWhatsThis with a caption of "What's This?". Finally, place this code in the MouseUp event of the command button:

 Private ThisControl As Control
Private Sub Command1_MouseUp(Button As _
	Integer, Shift As Integer, X As Single, Y As Single)
	If Button = vbRightButton Then
	Set ThisControl = Command1
	PopupMenu mnuBtnContextMenu
	End If
	Set ThisControl = Nothing
End Sub
Private Sub mnuBtnWhatsThis_Click()
	ThisControl.ShowWhatsThis
End Sub
