Description These IDC scripts help with the reversing of MSVC programs. One script scans the whole program for typical SEH/EH code sequences and comments all related structures and fields. Commented are stack variables, exception handlers, exception types and other. It also tries to fix function boundaries that are sometimes incorrectly determined by IDA. The script to run is ms_ehseh.idc.

The other script scans the whole program for RTTI structures and vftables. For some simple cases, identifies and renames constructors and destructors. Outputs a file with the list of all vftables with referencing functions and class hierarchy. The script to run is ms_rtti4.idc.

For more information see the following OpenRCE articles written in conjunction with these scripts:
