Class Informer IDA plug-in
Author: Sirmabus # Views: 30413

My new IDA plug-in based on Igorsk's excellent article and IDC scripts.

[Download]

------------------------------------------------------------
Scans an MSVC 32bit target IDB for vftables with C++ RTTI, and MFC RTCI type data.
Places structure defs, names, labels, and comments to make more sense of class vftables ("Virtual Function Table") and make them read
easier as an aid to reverse engineering.
Creates a list window with found vftables for browsing.

RTTI ("Run-Time Type Identification"):
http://en.wikipedia.org/wiki/RTTI

RTCI ("Run Time Class Information") the MFC forerunner to "RTTI":

Example vftable output list:

Example vftable info set by plug-in:

Thanks guys.

I've done an update with some extra features and added exponential speedups by replacing string searching and processing with mostly binary methods.

I made a section on my forums for my IDA plug-ins where you can download the updates:
