Here is my issue.

My Gui library that I made supports timed events. Basically, I have a class called TimedEvent which users inherit from. They then do:

addTimedEvent(new DerivedTimedEvent(...));

However given the nature of timed events, I manage the memory afterwards.

So when the timed event has done its thing, my library calls delete on it. Although it runs fine, that is because the exe and the library were both built with msvc 2008. I think I might have trouble if I have 2 versions of the runtime, one for the lib, and one for the exe.

What can I do to fix this? I can't create a factory because the derived type is on the exe side of things. I also cannot ask the user to call delete since they might not have a way to keep track of time, or know if the event was delayed for whatever reason.

Thanks
