Why? Because they can do things that can't be done using native VBA, such as
resizing a userform in VBA. Basically, you are tapping directly into
operating system functions, extending the functionality, and often
increasing the performance.

I am sure that the question has more depth than that simple answer, but I am
not sure what.

Hello, I'm just wondering if someone could explain why they would make
calls
to Windows API? What this actually means, and what extra functionality
this
gives VBA? I've seen a few good examples which include things from win32
api,
but I'm a little lost.

Thank you for any answers in advance.
