Hi again,

I'll try to make it short:

Given a CodeClass obtained from a C++ source file (by calling
CodeElementFromPoint(vsCMElementClass)), I call get_Bases(&CodeElementsPtr).
For each base in the colection I want to get all its member functions. The
problem is that casting any CodeElement in the bases colection to CodeClass
will result in a NULL pointer (each element in the bases is of kind:
vsCMElementVCBase) and calling get_Children on each CodeElement returns an
empty CodeElements colection.
How should one treat the elements returned by calling CodeClass::get_Bases()
(for C++ source code) in order to be able to get the base's member
functions?

Note: the cast mentioned above (from base element to CodeClass) works fine
for C# source.

Thank you,
Flaviu

Hi,

I was actualy hoping to get the members of a base class (for C++ source
code) by using only the EnvDTE namespace. It works for C# but I was not able
to work it out for C++ without using the VCCodeModelLibrary namespace.
For anyone interested I will describe how this can be achieved (get the
members of a base class obtained by iterating through the CodeElements
returned by calling CodeClass::get_Bases()):

C#:
- cast each CodeElement in bases elements to CodeClass and call
CodeClass::get_Members(). It works.

C++:
- for each CodeElement in bases do the folowing:

VCCodeBasePtr vcBase = baseCodeElem; //baseCodeElem is a CodeElementPtr
contained in the CodeElementsPtr returnes by CodeClass::get_Bases()
CodeTypePtr baseClass;
vcBase->get_Class(&baseClass);
if(baseClass)
{
baseClass->get_Members(&baseMembers); //baseMembers will hold the
base class' members
}

Thank you,
Flaviu

Since the VC code model is somehow different from other .NET languages,
after some researchs I don't find the method to get the members of a C++
base class under EnvDTE namespace.

Thanks for your understanding!
