Hello Everyone

I started developing Window apps today and i'm using Visual Studio 2005 and coding in C, my fave language and i'm following a web tutorial. However, when the program is compiled i'm getting a link error.
I opened a new project and the error persists. Below is part of what the compiler displays:

 [size="4"][b][b]error LNK2019: unresolved external symbol _CreateWindowEX referenced in function _WinMain@16
\Visual Studio 2005\Projects\petProduction Management\Debug\petProduction Management.exe : fatal error LNK1120: 1 unresolved externals [/b][/b][/size][/i][/u].

Any ideas , any suggestions on what settings do I need to change?
Please refer any useful tutorials on windows programming using c/c++ . I know C# seems to be the most popular but i'm not familiar with C# yet and I don't intend to learn it now.

thanks

Your code most likely contains main() & you need to use WinMain().

MSDN for WinMain

No. Take a look at error message:

Quote

unresolved external symbol _CreateWindowEX referenced in function _WinMain@16

So the unresolved external is CreateWindowEX, and it's used in WinMain. He most likely need to link with user32.lib.

oops, I got confused

[dinisrainman]

I used WinMain. sarmanu how do I link to

user32.lib? 

. Is that a library within windows or part of visual studio itself?

[sarmanu]

It comes with Visual Studio. You can link directly from a source file (or header) using #pragma comment:

#pragma comment(lib, "user32.lib")

or you can link from project settings. Do this:
Right click on project name -> Properties -> Expand Linker tab -> Now, at Additional dependencies, simply write: user32.lib

You probably created the project as a console application, create it as a Win32 application, that is most likely the source of the error. Good luck
