I believe ClassView folder settings are stored in .opt file. Maybe you've deleted it?

I can exit VC++, go right back in, and all the classes will be moved back under the main project folder in ClassView. It doesn't happen every time, but every few days or so. I'm not physically deleting the .opt file or anything. I happens on my Notebook as well as my normal desktop.
Thanks for the input.

I haven't really understood how to add a message handler for a menu bar item. I just created an empty MFC project (MyApp) and then added a new menu item (ID_FILE_SOMEITEM).
Then through the Class Wizard on Mesage Maps tab I chose the view class CMyAppView and chose ID_FILE_SOMEITEM in ObjectIDs and then clicked on Command in Messages and clicked the Add Function button.
The class wizard created the function OnFileListen.
I added the
AfxMessageBox("Code Reachable");
line inside the function and when I built the project.....I was expecting it to give me a message box alert on clicking File>SomeItem
But Nothing Happens. Evidently I am making a pretty basic mistake in creation of message handlers.
Tell me what to correct.

ClassWizard has the annoying habit of sometimes changing the target class to something other than what I expect. Perhaps the handler got added to a class other than CMyAppView?

nope because I found the message handler function in CMyAppView class and I added the AfxMessageBox there!

Could I get some comment about the why and how the app have closed. Do Anybody knows a api function or MFC ?

PostQuitMessage(0) generally, or CDialog::OnOK ( or OnCancel) in a dialog based app spring to mind, but there are others.

I'll just also mention that if you also meant how could it be closing without your wishes, the most common way is you hit return in a dialog based app. Other than that, if that's what you meant, you'll have to be more specific.

When you run (in VC++6.0) in Debug mode and the app closes (by the user), appear on 'Docking view'window' - tab 'Debug', the messages:
The thread 0x3A4 has exited with code 32053 (0x7D35).
The thread 0x1B8 has exited with code 32053 (0x7D35).
The thread 0x498 has exited with code 32053 (0x7D35).
The program 'D:\MyProgram\Debug\MyProgram.exe' has exited with code 32053 (0x7D35).
I would like to know any shape to get some information like this about the program exit.

I have a problem with animating my OpenGL code in an MFC window. When I move the window the background leaks onto the screen. I was wondering if anyone knows what to do. I think you have to use the WM_ENTERSIZEMOVE and WM_EXITSIZEMOVE messages, but I am not sure. Also I was wondering if anyone knows if you can animate OpenGL in a dialog box?

First of all I'd recommend not using MFC. nehe.gamedev.org ( from memory, to be honest all I am sure of is nehe ) has a ton of GL tutorials that do not use MFC and will help you learn pretty much all you'd want to know. As for your sizing, I'd have thought you'd handle WM_SIZE to keep track of the changing size of your GL window, but if you're drawing onto the DC of the window, I don't see how you'd be drawing outside it.
There's no reason you couldn't animate GL in a dialog box.

Doesn't MFC make OpenGL calls unnecessarily slow? MFC isn't the best thing to go with 3D Graphics.

How exactly it slows OpenGL calls?

Relying on MFC code is like taking a chance, and I would not depend on it for game rendering.
MFC classes such as CArray, CMap, and CList that perform inefficient data copies. Also there are many redundant calls that MFC applications make.
|
|
|
|

Well, it's pretty obvious at this point that you don't have much (if any) experience writing OpenGL apps using MFC.

OpenGL is not only for game rendering. If you need to create a complicated 3D modeler with rich UI, MFC (or WTL) surely helps.

I find this statement mysterious. Please elaborate.

Well, since MFC doesn't wrap any of the OpenGL API, I fail to see that this would be an issue.

For OpenGL applications it is highly reccomended to register the windows class with style set to CS_OWNDC, which is (as far as I know) not something MFC will do for you. Of course, you can always do it yourself, but I've never noticed this in any of the CodeProject articles on OpenGL.

From what I can see, you can still use MFC in an OpenGL app.

Of course you can. My first MFC project was a CAD application with a heavy use of OpenGL.

Because if you're doing an OpenGL app, it's likely you don't *need* MFC for anything, and not using MFC gets you closer to the main message loop for rendering etc, plus while I think the effect MFC has on speed is overrated, I still think it's probably there and to be avoided when you're not going to do any real GUI anyhow.
Also, for me personally GL was a good excuse to learn Win32, which I always recommend.

I should probably reiterate the main reason for me. While there is no doubt you most certainly *can* do OpenGL in an MFC app, I recall that doing a Direct Draw game using MFC became a major pain when I started trying to get it to render in idle time, although as I recall that was actually because I started with a dialog based app and it was through this project I learned about WM_KICKIDLE.
Nevertheless, the main reason for me is the nehe tutorials, because they are an excellent source of info, and they do not use MFC, nor do any of the major OpenGL books. Therefore it's simply a case of conforming to the way information is being presented.
I guess also my bias is starting to lean towards only using MFC when I need it, based on the amount of time I'm spending without it. But I did not mean to imply you COULDN'T do it with MFC, only that there are reasons I personally wouldn't.

I would rather not use MFC but my project requires that I do. Anyway I am not sure if the OnSize will work, but I'll try. Also I am not drawing outside the box, it is that the picture leaks outside the box.
