VBReFormer

VBReFormer is a versatile tool. Most important it recreate the form- and vbp-files from compiled VB EXE-files. No source code is recreated, so it's not a decompiler.
Furthermore it can analyze dll's, ocx's, oca's and tlb's. E.g. tell what methods an ocx-control has.
However be advised that VBReFormer is programmed by a non-professional, and bear many sign of that. Nonetheless I, myself, have found it useful in several occasions.
Other than the original french version, it supports english and german.
