VB5 Decompiler

By oskiller ·
I need something which will allow me to either decompile or unmake an exe we have created. We created the exe, but have lost the source code. Unfortunately the person who compiled the source code did not compile the code from the regular working directory, and the directory in which the production code was, was not backed up and deleted. I've already tried the Dodi decompiler, but it only works on VB versions 1-3. I also tried to hex edit it, but the code area I need to look at is not readable ASCII text once it is compiled.

Sorry to say that there isn't a compiler for VB5+, only for type libraries.
Have you tried using an unerase or file recovery program to get the deleted files back? If this is a possibility and a utility like defrag hasn't been ran, then I would immediately stop all activity on the drive and get a file undelete program like one for Symantec or Fix-It and run it from the CD (unless it is already installed on the system) and try to recover the deleted directory and some of the VB files. At least then you could get some of the code back.

Sorry, I typed compiler, instead of decompiler

I would try doing a recovery, but the problem is the person who compiled the code the last time does not remember where the code was compiled from. We were going through a cleanup where all code was to be moved to one location and worked on in subdirectories from there. Unfortunately, this one was not. Might have been on any number of servers or machines which have had numerous things done to them since then.

Thanks for trying though.

There's no way to de-compile an executable and turn it onto a readable format. All decompilers can work at hexadecimal level or assembler, which may be not useful for you.
I'm (sure ?) that you make regular backups to your files. Based on the creation day of the .exe file, start searching your database backup file from the previous full backup of your strategie since the compiled day.
You mention many servers, ok, just search on each one. If you do not have a database engine with your backupsoftware, start making a new one with the backup info stored in the tape.
If you don't have those backup's, it's time to build a new startegie based upon this incident!!.
Another cool way to have your code safe and secure is to use Visual Source SAfe from Microsoft.

Hope it helps!!

Thanks for the advice, but the problem is the coder does not remember where they were working on the code from. It could have been a server or any number of workstations. Until recently, code was put all over the place, but I have instituted a "checking" mechanism to try and prevent this from happening in the future. All code is stored in one place, and "checked out" when someone wants to test or make a change. 4 previous versions of code will be stored at this point.

Possibly one of the 4 types of developer software at URL http://www.v-com.com/product/devsopr.html may help you out for decompiling. As far as the code in the directory that was not backed up and deleted check out SpinRite 5.0 at URL http://grc.com/default.htm. You may also want to check out a product called Media Editor found at URL http://www.dtidata.com/products_media_tools.asp. You can also check the web for used software companies NOT ebay or see if your local PC Users group can help as an inexpensive proposition to commercial software.

Thanks for pointing this out - it is under consideration at this point.
