I wish to do the following but can't seem to work it out.
I have a form with 2 text boxes txtStart,txtFinish and txtDuration. I
would like a user to be able to click cmdCal and the no. of hours and
minutes between the 2 times to be displayed in txtDuration. I need to
make sure no negative values are returned. ie if start time is 2300hrs
and finish time is 0900hrs it shows 14 hours not -14. Im sure this can
be all written in vba.
