    Any one with experience reversing a powerbuilder application?

    Hello all,

    I've searched far and wide on google and RCE boards but haven't found any tuts or hints on reversing powerbuilder targets. Anyone have experience with this? All the usual GetWindowTextA, GetDlgItemTextA etc. breakpoints don't seem to work for the registration dialog box. Thanks!
    I promise that I have read the FAQ and tried to use the Search to answer my question.

    As Above

    If its small and doesn't require dozens of dependent files, maybe you can send the application to me on my email.

    Lightbulb Just finished a powerbuilder app..

    There IS a powerbuilder decompiler of sorts, called DePB. I found it on one of the reversing boards in China. It's a demo version, and I haven't been able to find a registered version, or any info about where to locate the author. It has a few limitations, but was robust enough to me to make a keygen for my app after decompiling a few modules.

    The filename is "DePB 1.0.zip" in case you want to look for it. It's a handy tool to have in your arsenal. For those that are curious, PB code decompiles as nicely as java, meaning that it gives you function names, variable names, and everything else. Pretty easy to reverse when you have the original source!
