C++/Statistica DLL problem

When a program loads, and it is dependant on a DLL, does it load the dll in memory at startup and then refer to it as nescessary, or does the dll only get loaded when it is required and then disposed of when finished. I would be tempted to think the first option, but I need some confirmation. My problem is that I have to write a DLL in C++ to be used by STATISTICA that returns a different set of data each time it is called, and want to use a static variable to keep track of which set I am up to. I had also considered using a temporary file, but that seems like a fair bit of hassle to go to for a test rig.

It depends on how the dll is called by the exe, if the exe use LoadLibrary() and FreeLibrary() explicitely, you will have the 2nd case, otherwise 1st case.
