C / C++ / MFC

2-Nov-05 8:20

Hello everyone! Big Grin | :-D

OK, I got VC++ 6 yesterday, and I'm trying to make a Windows app, but I got no idea how! I looked for tutorials but they're all either for command-line apps (which I already read one) or for VC++ 2003... I've coded in C++ before, but not for Windows... I need a basic introduction to how to create a GUI/form/window from scratch. Anyone know? Thanks! Wink | ;-)

Yeah, that's one of the sites that are for VC++ 2003... Frown | :(

But I already figured out how to do it... Now I need to know how to retrieve the text from a text label on my dialog. Do you know how? Thanks! Wink | ;-)

I had a quick glance at this the other day and in certain places they give instructions for both VC++ 6 and VC++ 2003.

Haven't done any VC++/MFC for quite some time but, from memory, you may need something like GetWindowText() or GetDlgItemText().

Also see this[^] article.

To get/set a control's text, use GetWindowText() or SetWindowText().

A good book on MFC and the basics of Windows programming is Programming Windows with MFC by Jeff Prosise[^]. You can find cheap on EBay here[^].

totally agree...the Prosise book is a great MFC book. I also have the Petzold book right next to it (programming Windows 5th Ed)

Yeah, that GetDlgItemText() worked! Thanks! Big Grin | :-D

And I'll buy that book if I find it on a store, you need to be very wise and powerful and have tons of patience to convince my dad to buy something off eBay... Thanks! Big Grin | :-D

Now, I got into new trouble... I accidentally put in a breakpoint in some file which of I can't remember its name... How do I remove all of the breakpoints? I can't run my program anymore! Frown | :-(

Thanks!

THANKS very much to both of you! Big Grin | :-D

[Edit]
Nope, didn't work... I did what you said but there are no breakpoints listed! I try to run the application but I get this message box:

User breakpoint called from code at 0x7c901230.

And then it shows me an assembler code file with an arrow before this line:

7C901230 int 3

How do I fix that? Thanks! Wink | ;-)

Check the call stack to see what caused this to happen. It's possible that your code called a Windows or C run-time library API with a bad argument.

I started with the Scribble Tutorial[^].

It's a *very* simple MDI "art" program that takes you through most of the common stuff such as events, doc/view architecture, dialog boxes, device contexts, file I/O etc...

Good Luck Smile | :)

number o fcontrols limited to 255?

3-Nov-05 14:42

Ravi Bhavnani;
Yep, I was using delete incorrectly... Poke tongue | ;-P

Miszou;
Yeah, it looks interesting... I'll take a look at it when I'm not falling asleep. Cool | :cool:

Thanks both of you! Big Grin | :-D

It seems Visual C++ dialog boxes limit the number of controls to 255. I tried adding more controls but it keeps reverting to the select tool. How do I get around this? Thanks!

why the he** would you EVER wanna put more controls than that on a form?

But seriously, I think if you really need to do that, you might wanna try adding them at runtime.

Client requirements. So there's no way of changing the limit? Adding it at run-time is my best bet? Doing that might complicate things?

i think you can add more controls by changing the id of the control from default to your custom names ( ie IDC_XXXXX1, IDC_XXXXX2 in to custom ones)

BTW: how u tried to create the controls? simply copy-> paste ?

Ninety-eight percent of the thrill comes from knowing that the thing you designed works, and works almost the way you expected it would. If that happens, part of you is in that machine.

no, this is a know issue... the only way to get rid of it is to add the 256+ controls at runtime...
