Parsing C++ Source

C++/CLI

hi all.
i have big problem and hope that someone can help me. i'm doing my bachelor now and i should read all function declarations from source files of Visual Studio C++/CLI working project. My program should be made in VS too(C# or C++/CLI)... The best option would be if i could get the whole AST from source. i've read a lot of articles and as i understood i should use a parser like "ANTLR", "COCO/R" etc. So what i'm looking for, is an example which explains how can i get AST or at least a list of function declarations in VS using "ANTLR" or smth else. I've also found that it may be possible to parse C++ source with CppCodeProvider, but found no information how i can use it.
Waiting for your replies.
P.S. Sorry for my bad English.
