C++ Debugger visualizer (natvis file) : Display the most derived class

    Question

  •      Hi,

    I'm migrating the class visualizer from autoexp.dat (VS 2008) to the new format in VS 2012 (.natvis file).

    I have a problem, I can't find any solution to display the most derived type for an object display in the Watch panel.

    With the autoexp.dat file, the syntax is simple : "MyInterface =<,t>".

    But with natvis file, I try lot of syntax, watch on Microsoft documentation, but I don't find any solution.

    In VS 2008, with the syntax "<,t>", when you display a pointer on a class ("MyInheratedClass") which inherit from "MyInterface", the debugger display the pointer address and and the most derived type "{MyInheratedClass}". I want the same feature with VS 2012, using the natvis file.

    Can anyone help me to find the good syntax with natvis ?

    regards,

    François.

  • I don't have any further information on this. Queries to internal alia haven't shaken anything loose so it looks like it's not supported in the .natvis syntax. I'd recommend creating a feature request bug at connect.microsoft.com.

  • .natvis uses new keyword : type

    e.g. below will show actual drived class in base class.

    <type>
