Hi
I don't use control tip text as:
a) it doesn't fire unless the control is 'at the top'
b) there is a slight delay before it triggers
c) its not that obvious anyway
However it can be done quite easily using a label on the main form whose caption is updated by mouse move events.
Attached is a form & datasheet subform with mouse move events on all parts of the form & subform.
The main form includes a label in
large magenta text which shows the required information
It isn't necessary to know the position of each control for this to work.
In the screenshot the mouse is over the Address line field in the subform
IMPORTANT:
1. Add a mouse move event to the detail section of the main form to hide the label & its caption. If necessary do the same on the form header/footer
2. Do NOT use this idea if your form includes a timer event otherwise you may get very irritating flashing and issues with controlling the mouse
NOTE:
The main purpose of this example was originally to hide/show the subform and adjust the form height / control position at the click of a button
