Visual studio C++ IntelliSense issue

Question

I seem to be having two issues with my project after I converted from VS 2005 to VS 2010.

IntelliSense: command-line error: invalid macro definition: _WIN32_WINNT>=0x0501

And I also cant seem to be able to do a "Call Hierarchy" on any of the methods or properties.

I would appreciate if someone can help me with these. Thanks

Answer 1

Decided to ignore the intellisense warnings. The call hierarchy wasn't working because I was in the release mode. Should be in debug mode.

Answer 2

I just encountered the same issue - the same error message, the same non-functioning call hierarchy and badly-working Intellisense.

The problem was with the preprocessor flags in the project, the following were defined:

WIN32;_DEBUG;WINVER=0x501;_WIN32_WINNT 0x0501

Notice the lack of = after _WIN32_WINNT. Adding the = fixed all the issues.

P.S., this is a Console application that doesn't use any of the Windows header files, which is why the lack of the _WIN32_WINNT macro did not cause a more severe problem.
