Charlotte, But I did do structured programming driven by Dijkstra (http://en.wikipedia.org/wiki/Edsger_W._Dijkstra ) works - do you believe me?! :) And nowadays I'm not using almost at all "one exit point" principle in C#/VB.NET programming - I can use "finally" or "using" programming language constructs, and .NET's garbage collector works well for me all the days of the week :) If not I can use GC.Collect(...) and other forced used memory collecting techniques... -- Shamil -----Original Message----- From: accessd-bounces at databaseadvisors.com [mailto:accessd-bounces at databaseadvisors.com] On Behalf Of Charlotte Foust Sent: Wednesday, June 24, 2009 9:00 PM To: Access Developers discussion and problem solving Subject: Re: [AccessD] Learning .Net -- PHP Instead? I've noticed that in VB.Net too, but I also notice that the syntax checker complains if you do that in functions. With respect to the links you provided, I wonder how many of those rabid "multi-pointers" have ever actually used structured programming techniques to design program flow? Probably few if any, which means they don't really know what they're arguing about. It boils down to "this is easier for me, so it must be right". Just because it the new wave, doesn't make it a wonderful idea. Bah, humbug!!

Hi Arthur and Charlotte, I used to use the same "one exit point" principle over the years (especially in my VBA programming) but I must note it's becoming obsolete nowadays: I do not use it almost at all anymore in my C#/VB.NET development. Have a look what is the reasoning behind this "new approach" to not bother about "one exit point" principle: http://ubuntuforums.org/showthread.php?t=631745 http://discuss.joelonsoftware.com/default.asp?joel.3.325456.34 Everything seems to be changing in programming these days but one who has been in programming for some time can rather clearly see we're "just" getting repeating/rethinking of "good old habits" but on higher current level of evolution spiral of computer science, programming methods and practices... Thank you. -- Shamil -----Original Message----- From: accessd-bounces at databaseadvisors.com [mailto:accessd-bounces at databaseadvisors.com] On Behalf Of Arthur Fuller Sent: Wednesday, June 24, 2009 6:43 PM To: Access Developers discussion and problem solving Subject: Re: [AccessD] Learning .Net -- PHP Instead? Yup. Over the years I have learned to accept this wisdom: each procedure or function should have exactly one exit point. Define the result variable and set it within your case statement, then jump out and return the result variable. No headaches or scratched foreheads that way. A.
