GetModuleHandle(NULL) is also in several places. Maybe it's OK, but why
not use the hInstance global?
Global variables are bad(TM). With GetModuleHandle(NULL) there is no need
to maintain a global hInstance. The other reason is there is no WinMain
which has the hInstance parameter. So you'd require to set the global
hInstance somewhere else and you have to make sure this occurs before
the first reference to hInstance. GetModuleHandle(NULL) was used explicitly
to reduce complexity.

Globals are not really bad(TM), for things that really are global.
But, a redundant global is definitely bad, so the global hInstance
should be removed instead.
