Cannot load user32.dll from extern C file

[chris_helloworld]

user32.dll should already be loaded and the msdn documentation doesn't actually specify what happens if you call LoadLibrary on a dll which is already loaded, though I see no reason why it would not work ok. Did you ever try using GetLastError ?

You can always try using GetModuleHandle to get the handle to the already loaded dll if you really do want to use GetProcAddress. (though I do agree with squidge that this really isn't necessary).

It does. It just takes a closer read.

The system maintains a per-process reference count on all loaded modules. Calling LoadLibrary increments the reference count.
