i can already think of 3 or 4 places where we need to search for a tour. there will probably be even more places where we need to do this. it is very easy to see that if we can come up with a way to re-use the same form we will dramatically reduce development time.

form re-use gives us:


gee, the above list has every single desirable trait a developer could aim for. i might add that the above list is by no means complete. this is darn near a pot of gold at the end of the rainbow. gee, faster, better, cheaper?hum how did they make the 6 million dollar man?

there are several approaches to solving the above problem. one approach is to "pass" the name of the form that the "search form" should load when a tour is found. however, we might not want to load a form after the search (maybe we want to print a tour). hence, the best solution is to not use a event on the form to launch another form.  yikes!, this means we digress from the event model a bit  (hey, it is just a tiny bit for a huge bonus).

what we do is "wrap" the form in a function subroutine and call it. it is that simple. while this approach does adds a few lines of code, we get instant re-use.

notice in both cases we are able to re-use the "same" tour search form.

i should note that this simple technique is not used by most access developers. in fact, to get access to do this we have to use a bit of a trick. the trick involves opening a form in dialog mode (this will halt the calling event code). to continue, we set the form's visible property to false. this causes the form to drop out of dialog mode, and the calling code continues. the values of the "non" visible form can then be used. after we get our values, we then close the form.

the above advice is nothing new, but one must always seek to improve design and coding techniques. re use of screens is an obvious area for reducing development time. the above simple change in design approach saved large amounts of time. if your application does not have too rich of a interface, then your mileage will vary
