I am looking for an old DDESpy tool.
Does anyone know where I can download it or something like that?
Found: http://filedb.experts-exchange.com/incoming/2009/06_w26/153525/DDESPY.exe.txt (rename to exe, remove the txt extension)
This is part of Visual Studio 6 and does not officially download. You should find the distribution of VS6.
This MSDN thread is talking about replacing it with Spy ++.
