    Decompiler....

    Hey guys!

    Is there a program that can de-compile the source code of a program?
    I was just wondering...

    Thanks!

    the way that vb apps are compiled... a decomplier wouldnt be real useful anyway... the code wouldnt come out how it was before you compiled it

    Isn't VB7 actually .NET? Isn't that fairly simple to decompile?

    Actually, the VB3 decompiler provided you with almost the exact original code... aside from variable and function names.

    I would think VB7 would be easy to decompile.... Because i think vb7 compiled executables are formatted similar to java programs... byte codes. Not sure tho.

    From what I heard, the whole .NET lacks the security when it comes to compiling/decompiling; main reason I haven't switched to NET yet.

    There are code obfuscators out for many different languages, including VS.NET. They screw around with the code, trying not to hurt performance, but making it virtual gibberish when decompiled.

    .NET compiles to IL language... all .NET languages compile to the same medium

    The RezQ thing is a start but...
    Note: VB RezQ does not recover the source code within subroutines.
    However - if you are developing software but not using any source control and backup methodology then whatever you are developing probably isn't worth recovering anyway.

    Unless you use the obfuscator that ships with .NET 2003.

    VA for me. Seneca(WV) all the time and the Whites (NH) for snow and ice when I can get up there. Only made it to the Gunks once but loved it.
