Why do MFC programmers love dialog based apps so much?
-
Maybe because with an SDI app you have screw around with a derived CFrameWnd, a derived CFormView, and deal with the idiotic (in my opinion) document/view architecture, either ignoring it (which isn't easy, BTW) or using it (which isn't smart, in my book), whereas a CDialog is simpler because MFC and the high school kids that wrote it don't get as much in the way of doing what you really want to do, which is get something working, instead of cursing at Microsoft's subversive plot to bog all programmers down in the quagmire of MFC while they (Microsoft) take over the world writing code in Pascal??? http://www.pseudodictionary.com/ramblerant[^] :-D Marc Help! I'm an AI running around in someone's f*cked up universe simulator.

How did you know that deep in my past I had some Unix experience? ;) But seriously, I'm writing applications based on someone's framework. If they provide the source code doesn't it make sense to have a look at the quality of the code? If they don't provide the source code at least let's look at all the constants and see if they missed something in the docs that maybe I need to know about ;) Rob Manderson http://www.mindprobes.net

After posting I had some further thoughts. If you've looked at any of my code (hint, lex and yacc demo) you'll see that I do a LOT of ASSERT and ASSERT_KINDOF tests, and AfxIsValidString etc kind of tests throughout the my code. Rarely do I hit a case when the tests fail on code that I wrote that uses code that I wrote because my mind is in that problem space. But if I'm calling a function someone else wrote then by definition my mind isn't in the exact same problem space as the author of that function. So I look at what they wrote and more importantly what they're validating about what I pass as arguments. Do they trust me as a caller? Do they expect me to pass a buffer to which they'll write yet not require I pass the size of the buffer (and make damn sure they don't overwrite my buffer)? You can bracket calls to code with exception handling all you like but if the third party function you're calling does stupid things then you must expect to suffer from unexpected side-effects and odd bugs. Overall, by that standard, I think MFC does a pretty good job of protecting me from my own assumptions about their framework. Rob Manderson http://www.mindprobes.net

Not strictly speaking, but what you end up to very often is a mere ::DialogBoxParam() function call with a reference to the .rc dlg template, which is more or less what we do with a CDialog-based app. Nishant S wrote: Oh!

If I were a dev lead, I would prevent anyone from writing serious MFC code before they have read and learned Charles'Petzold bible. Unfortunately, in this mad software industry, it's more about in how little time you get that damn popup box ready, rather than writing a popup able to accomodate further requirements (especially changing specs! :(( ).

Haven't you noticed that the Windows API uses the Pascal calling convention?

I think it could also be blamed on a combination of feature creep, available time remaining on the schedule, and management not wanted to admit they were wrong about the initial design and that the programmer writing the app was right all along. You may think I'm being a bit sarcastic about that last item, but I've seen it happen more often than not. ------- signature starts "...the staggering layers of obscenity in your statement make it a work of art on so many levels." - Jason Jystad, 10/26/2001 Please review the Legal Disclaimer in my bio. ------- signature ends

So often you see people develop a dialog based app, then they add a menu to it, a status bar, make it resizable, make it scrollable, put a view inside it, add a document save-load option etc... Then why did they even go for a dialog based app? What they needed was an SDI app with a CFormView derived view. It's amazing how they take a dialog app and do everything to try and make it behave like an SDI app :-) Nish

I have been writing MFC apps for many years. I have yet to do a dialog based one! In my time I have only done 1 SDI type app as well (back in VC 1.5). These days I always stick to MFC MDI as I know it so well. I am scared of dialog based apps. :omg: Roger Allen Sonork 100.10016 Were you different as a kid?

:)Probaable reasons... 1. When people migrate from VB to VC, dialog based app is (comparatively)easier way to shift. 2. When Document-View architecture not required in project. Anand

Having the source code for someone elses library/application is great for the reasons you mention. And it is very much possible to grep around to see what the hell is going on. :-D (Very valueble indeed!) -- In the land of the blind, be king! Some day, Dominion, some say prayers, now I say mine.

:) My facetious answer was meant to convey the situation where a programemer may decide that they want a quick app - so they start with a dialog based app and work from there. Then they realise they have a bunch of options to offer, so they shoe-horn in a menu. Then they decide to add status info, hence a statusbar - and on it goes. Obviously not a common scenario for most programmers but I do remember doing exactly this when I was first starting out ;) cheers, Chris Maunder

Just FYI, you can add this code to the CFormView derived class's OnInitialUpdate function to remove the "recessed" border on the SDI app:
ModifyStyleEx( WS_EX_CLIENTEDGE, 0, SWP_DRAWFRAME );
