Mike,

>I would like to change the caption of a command buttong or perhaps a label using a dll. Is this possible?

You can't do that from a regular DLL, since VFP paints it's own controls. But if you're making an FLL (which is a special kind of DLL which runs inside VFP's memory space) you could do this. For more information on this, see MSDN library/VFP help.

Regards,
Armin
