And what are you storing in "Pulse"? A pointer
that you got from the field in the first form? That
pointer will be invalid once the first form is unloaded
and the field memory is deallocated along with the
rest of the form's memory.
You will need to allocate some memory of your own,
put -that- pointer in "Pulse" and then use StrCopy()
to -copy- the data from the field in the first form into
the memory being pointed to by "Pulse".
Once you've done that, you should be able to put
that data into the field in the second form.
