Hi,
Puzzled by your comments. There shouldn't be any problem sharing a dataset
between multiple forms. Of course all forms will have to be displaying the
same record at the same time - it is the same dataset after all. If you want
a seperate copy for each form then you need to do just that (possibly by
creating a datamodule instance for each form at run time and linking them in
code). Similarly there shouldn't be a problem with creating two instances of
the same form. However you will have to use a different pointer for both
instances of the form (your mainform variable can't point to both).
I'll grant you that doing these things requires a rather more sophisticated
application. However they are certainly possible.
David.
