How to use Pythonwin's ability to access windows dll's???

[sam schulenburg]

I can access windows dll's using Sam Rushing's calldll.pyd and windll.py. My
question is are thes features built into Pythonwin? I find that I can use
win32ui.LoadLibrary('MyDll') to obtain a PyDll object, but I can not find an
example on how to use this Pydll object to access a function within the dll.
For example:
MyPydllobj = win32ui.LoadLibrary('kernel32.dll') will obtain the object, but
how do I access the Beep() function within the dll?
