Sorry I don't know your level of foxpro knowledge, if your not familiar with visual custom class I think you should read books about it.

In resume:
- you create your class
- In foxpro option, you make youur class available for use
- in form designer you choos your class instead of regular foxpro class
- you click and drop you toolbar class into your form


If the question is how to make it visible, I would code it into the refresh section of the toolbar or in the buttons themself depending of what you wants.

Good luck.
