Identify a VB executable and decompile 2

[jworley]

Hi,

One of my clients had a bepoke app written, he doesn't know what language the developer used, I note that it uses an Access database and am assuming that it is VB. The company who developed it went bust and you guessed it, no source is available. Changes need to be made with it as it relies on a hard-coded ODBC connection to an off-the-shelf app whose proprietary database structure has changed due to a version update. I know this is asking a lot, but does anyone know of a decompiler for VB ? Jim Worley

Don't know of any decompiler for any version of VB later than VB4.

OK, is there any way one can identify what version of VB the exe was compiled with ? Jim Worley

One way is to right-click on the exe, and select Quick View. Scroll down to the Import Table section, and see which VB virtual machine it imports from.

Have a look at the dependecies of the EXE - use the Depends tool that comes with Visual Studio 6. If the EXE has a dependecy of MSVBVM60.dll then it was compiled with VB6, if it has a dependency of MSVBVM50.dll then it was compiled with VB5.
