I'm not sure how it might affect the operation of the button - assuming
you're referring to a Command Button (Control Toolbox) - but you can try
this;
In Design Mode right-click the button to Format Control & set the Wrapping
Style to InLine with Text, OK out.
Leave the button selected, go to Format>Font, tick the box for Hidden.
Am not sure how this pans out in the long run, but it does seem to hold some
promise in the limited time I played with it. The limitation is that the
button has to be in a text line or table cell due to the InLine wrapping.
Since the command button has no 'visible' property this is the only thing I
can suggest. Someone may have a VBA solution, so continue to check back.
Please post back with your results.
