an unresolved external symbol linker error occurs when a compiled file (but not linked yet) uses an external symbol, such as a function or a variable declared as extern, but found nowhere in the reste of the project files.
that's why we have to #include some files sometimes...
the linker cannot find for beginthreadex() and endthreadex() for two major reasons...
1) you didn't wrote the function names correctly (C/C++ are case sensitive, so be careful to the caps...).
2) you don't include the correct header file (.h)where these two functions are defined. as they are standard headers (not defined in your project, but in one of the compiler folder), use #define<>.

Do you mean I need to add in #define beginthreadex and #define endthreadex at the beginning of the program
|
|
|
|
|
#define ???? no never, i never talked about that, i said #include

After I add the #include <beginthread> and #include <endthread>
its still got error
error C1083: Cannot open include file: 'beginthreadex': No such file or directory

the #include file is not in the same directory where ur application is present
so #include foldername//abc.h
foldername in which abc.h is present

When I build a console application , it always appears with the default application icon (the blue buildings). How can I change this icon?

Have you tried simply adding an icon to your app using the resource editor in Visual Studio? That should be enough.

I say a more time : CONSOLE APPLICATION

I've just tried to do this, and managed to get it to work. Here's what you do...
In VC++, select the following menu item: "Project" -> "Add To Project" -> "New..."
From the resulting window select to add a Resource Script (give it any name, I don't think it matters). You'll now have a "Resources" tab added to your project from which you can right-click and do "Insert...", and select Icon from the resulting box. Then just edit your icon.
Worked for me.
I guess it would work just as well if you selected "Import..." instead of "Insert...", and selected a pre-defined .ico file.
Hope this helps, 'bod

So what? You might stop repeating that. Being a console application, or even a "CONSOLE APPLICATION" if you don't mind me yelling back at you, has nothing to do with whether your application can contain resources or not.
Maybe you created your application with one of the wizards and it didn't add a resource to it. But I already suggested adding a resource yourself using the VS IDE, and you said many people told you the same before. Instead, you just keep repeating that it's a console application as if that were of any relevance.
I simply told you to add a resource to your project and put your icon there, because I didn't think you needed step by step instructions on how to find the appropriate menu option in the IDE to do so. However if you can't find it yourself, feel free to ask and somebody may help you.
Simply repeating and yelling "CONSOLE APPLICATION" just make you look err... well, let's just say it doesn't look very good.

Hey all,
I recently got MS VC++ 6 Pro and Im having a problem when compiling. I even tried uninstalling it, reinstalling intro, and i still have the same problem here. Its a Win32 dialog app. Here's the problem:

What can cause this? Everything looks the same as it was in the settings. Any ideas? Thanks

Like the message says, it's a linker internal error.
Have you installed the latest service pack (SP6, I think)?
Is any of your .obj particularly large?

Im downloading the update right now. However, I don't think that has to do with it. When i reinstalled intro version, it was coming up with the same error and Ive been using that for years now! I've tried making just a new project and starting from scratch... just a little dialog-based app. Still get the same problem. So no big file sizes. Any help?

Nope, didn't work. Still same errors. In settings, under link, this is what it says in the project options:
/nologo /subsystem:windows /incremental:no /pdb:"Release/123.pdb" /machine:I386 /out:"Release/123.exe"
This should be good, right? Thanks

Nevermind. I installed the wrong update. Apparently, the 60 meg one is the one I needed. DOne and Done. Thanks
