CInternetSession and Unicode

Environment: Windows NT 4.0 (Swedish) with servicepack 3, Visual C++ 5.0 with servicepack 3.

I have a MFC EXE application with a CDocument derived document class. In this class I have a CInternetSession member variable (private, default constructor used). In a Unicode (UNICODE and _UNICODE macros defined, Entry-point symbol wWinMainCRTStartup in Link Output defined) debug build the constructor for the variable fails, resulting in that the creation of the document fails, and the application exits.
It works with no problems whatsoever in a normal (non-unicode) build.
Is this a known problem? How can it be solved? I have searched the MSDN without any hit.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

At this time, the WININET APIs, which CInternetSession (and all of its friends) use, do not support Unicode: they simply fail.

If you must use the WININET APIs in a Unicode MFC app, you must code to the APIs directly, and you must make sure you call the A-versions of the APIs explicitly. That means that you'll need to convert to and from ANSI and Unicode for any strings that are going back and forth between your app and the calls to the APIs.

That stinks, but that's the way it is.

Thanks Mike, for clarifying those things. I hope that Unicode support will be added in the near future.
