>How can I create a label to be used on a main static form and the caption be defined in another from or program on the fly?

Heya Steven -
In the past, I usually had put labels in a classlibrary, then
dropped the label on the form at design time.
Then ? the caption value could be dynamically set at run time, usually from some method code in that class for that label.

but I may have failed to understand your question, alas.
