I want to load the same dll e.g. Lib.dll multiple times!

-> need creating a new process (CreateProcess function) for every LoadLibrary!

Anyone have an example or some hints?!

Thx and greets

It sounds like you want each instance of the DLL to have separate data segments. That's the only reason I can think of for the question.

The only way to achieve this is to make sure that each time you call LoadLibrary, the DLL has a different filename. Copy the DLL to a temporary file each time you need to load it, making sure that the name you use is different from any loaded instance of the DLL.

I echo the comments above that encourage you to re-design the system architecture.
