So I don't know if this is the right place to post this or not, but
I'm having an issue with the compiler that does not make sense to me.
I have read MSDN on the error message, but it still does not make
sense to me as to what is so wrong about it.

Below are small related snips of the source code of various CPP/Header
files as applicable to the error message.

The build error is as follows:
1>Win32CppSvc.obj : error LNK2019: unresolved external symbol "void
__cdecl MyCppSvcGUI(void *,int)" (?MyCppSvcGUI@@YAXPAXH@Z) referenced
in function "int __cdecl InstallSvc(void)" (?InstallSvc@@YAHXZ)
1>C:\Users\Wes\Documents\Visual Studio 2005\Projects\Win32CppSvc\Debug
\Win32CppSvc.exe : fatal error LNK1120: 1 unresolved externals

Any ideas are greatly appreciated!
