Check for loaded DLLs

Posted by Shyam Sundaram on August 6th, 1998
Hi , I wanted to pass on one of the methods that has helped in the past, in debugging client server applications, in which you may have several version of your dll. Making use of small utilities like WPS/Killer/Nuke in determing the DLL that is lodaed at run time. This helps you to sometimes sort of understand in which portion of your application, a problem occurs.

This becomes really useful when you distribute your software to users not necessarily in the same location and on diverse platforms (w3.1,w95, nt and so on). Sometimes a dump of the active dll's helps you nail down the problem.

    Sounds like a good idea. But I am reminded of the old joke:
    Do you know how to keep an idot in suspense?
    I'll tell you tomarow!
    What I am getting at of course, is where is the example?
