title: C++ DLLs newer version
body: <p>All, </p>
  
  <p>I have a C++ COM DLL written using Visual Studio. All the interfaces have GUIDs in idl and rgs files. We want to create a new DLL with brand new GUIDs as we want it to co-exist on the same machine with the old one but with different logic. The number of GUIDs is more than 200. Is there a tool that finds the GUIDs and replaces them ? I noticed for every GUID in idl file there are 3 same ones in the rgs files.</p>
  
  <p>I am not really into C++ COM but I have to get this done :</p>
  
  <p>Rgds,
  MK</p>
