    all,

    first post in this section, i have an application and seem to have lost the VB source code, is there anyway that I can get it back given that I have the .exe file?

    paid about €2k for it 5yrs ago and have problems with it not pointing to correct file locations etc so need to go in and look at it

    company want to be paid again for the source code as they supplied it with the package and it went walk about

    There are a number of decompilers available for visual basic but you will have to tell what version of VB (V5/6/.Net). Bear in mind that even the best decompiler will not give you the exact code that was used to create the .exe but it should be enough for you to make your changes and recompile if necessary.

    to figure out which version of VB was to open up the .exe file in notepad. Do a search for MSVBVM. If you find MSVBVM60 then it is VB6. If you find MSVBVM50 then it is VB5. If you dont find it then it was either written in .Net or possibly not written in VB at all.

    Reflector by RedGate software is the most popular free decompiler for .NET apps. If the sware was only written 5 years ago then theres a reasonable chance its a .NET application so give reflector a go
