I'll back up what Ajay and Joe said. I converted a large project gradually, but the gradual bit was replacing all the char's by TCHAR's (in a project with multiple DLLs) and of course all the other stuff which has to be consistent with that, over a period of about a year. When I thought I had finished, I defined UNICODE and _UNICODE in the projects, and it became Unicode. Of course I had missed a few things but it only took a few hours of bug hunting. But I did it in VS2005 - it may be harder in VC6.0.

No need to type any of these #defines anymore. If the OP is using VC6 (like I read in the first post), I think he must use the #defines.

No need to type any of these #defines anymore. I just went and looked. You mean Configuration Properties ~ General ~ Character Set ? I didn't know that existed. Thanks for pointing this out.
