Check whether a Visual C++ 6.0 project did support unicode or not?

Question

I need to know if a Visual C++ 6.0 project supports Unicode or not. How can I check that?

Answer 1

If the project is compiled with Unicode support, then the preprocessor directive UNICODE (or _UNICODE ) will be defined. Testing to see if this is defined will give you your answer:

#if defined(UNICODE) || defined(_UNICODE)
    // The project is compiled for Unicode
#else
    // The project is NOT compiled for Unicode
#endif

You can also check this from within your project's settings.

1. From the "Project" menu, click "Settings".
2. Select the "C/C++" tab.
3. In the "Preprocessor definitions" section, check for the presence of UNICODE and _UNICODE .

If you have a project that is not currently targeting Unicode, but you want to see if it can , then the best thing to do would be to define these preprocessor directives, and then try compiling your project. If it succeeds, then you're set. If it fails, go through and correct the errors emitted by the compiler.

Answer 2

#ifdef UNICODE
#   error Success!
#endif
