How to build UNICODE in the Visual C++ 6.0

In the Visual C++ 6.0, if you want to compile UNICODE code,

You should chagne some configuration.

1. in the project, you delete _MBCS and input _UNICODE.

 [Project] -> [Settings] -> [C/C++ tab] -> [General Category]

  in the Preprocessor definitions, change _MBCS to _UNICODE

2. If you meet "Cannot open MFC42ud.dll(mfc42u.lib, mfcs42d.lib, or etc)"

 Copy the MFC library to your local machine. 

 From CD \VC98\MFC\LIB\all files to \Microsoft Visual Studio\VC98\MFC\Lib\ directory

3. [Project] -> [Settings] -> [Link] 

 In the Object/libary modules, insert mfc42u.lib

And compile the source code.

If you will see "msvctl.lib:error LNK2001 :unresolved external symbol _WinMain@16~~~"

 [Project] -> [Settings] -> [Link] 

 In the Entry-point symbol set "wWinMainCRTStartup"

That's all.
