Getting scope information from C++ header and source file.

Hello,

I am developing a Visual Studio Extension. 

What I want to achieve:

When the user clicks anywhere in the editor, I want to show the cursors scope information (Function and class name) in a separate Tool Window.

How I am trying to achieve:

I am using the CodeElementFromPoint method on FileCodeModel to get the function or class name. But that method works great for C# code but for C++ code it works only for .cpp files.

Code Snapshot:

EnvDTE80.DTE2 dte = (EnvDTE80.DTE2)ServiceProvider.GetService(typeof(EnvDTE.DTE));
            TextSelection sel =
            (TextSelection)dte.ActiveDocument.Selection;
            TextPoint pnt;
            if (sel != null)
            {
                pnt = (TextPoint)sel.ActivePoint;

                CodeElement elemFunctionNew = dte.ActiveDocument.ProjectItem.FileCodeModel.CodeElementFromPoint(pnt, vsCMElement.vsCMElementFunction);

}

Does anybody have a better idea how to achieve it or which approach should be taken for C++ language?

Thanks in advance.
