Only they really aren't tool tips. Instead of showing up when the user hovers over a control with the mouse, I'd like them to show when a textbox gets focus.
As as sort of aid to help the user fill in a form (the user would also have the option of turning these on and off).
I'm working now with an invisible form with a label, which shows my tool tip . . . but it's sorta difficult, and I didn't know if anyone else has a better suggestion . . . ?
If Search was working I'd refer you there but since it isn't the only thing I can think of is that I believe that Aaron Young some time ago posted a solution. You might contact him directly.
If you are using the form-method just so that you can turn the tooltips off and on, the you might consider storing the tooltip text in an array or in a res file. You can then set all tooltips to "" when you want to "turn them off" and reload them when needed.
