    Posted: 06 December 2007 at 7:46am
Hi,
 
Can you please tell me where can I find an example using the ToolTipContext?
 
Is it possible to use it with a VB Image control, for example?
 
Thanks

Sorry, ToolTipContext is internal class and can't work as separate control.

Hi and thanks for the answer.
 
No problem about the TooltipExtension, but what about the Tooltip Window as in this page?
 
 
Can you point me to an example or sample?
 
Thanks

    ' Class for the creation of Rectangular and Balloon Multiline Tool Tips.
    '
    ' See Code for details on Syntax, variables and constants.
    '
    ' This Class Module works by sub classing the parent control.
    ' Works with most of the common controls, the ones it will not work
    ' with are controls that do not support tool tips themselves.
    ' There are some controls that support tool tips but complain with this
    ' sub classing module (only Microsoft knows why!).
    ' Do not use the native tool tip with the parent control and this together,
    ' you get overlapping tool tips!
    '
    ' This class module is also know to work on the following OS's (all Win32)
    ' Windows Me
    ' Windows 2000
    ' Windows XP
    ' MSDN Docs state that IE 5 or higher is needed for Balloon tips
    '
    ' It's usefull as it is written, so give it a try!

    ' As brought to my attention on 01-DEC-2004
    ' Parts of this class was writen by Eidos on PSC

    ' and changes to for my needs.
