RE: DLL GetModuleHandle strange prob..

[Ben Miller <Ben.Miller@Mercia.Com>]

Hi Jeremy,

I believe that GetModuleHandle will only return a handle to a module
that has already been mapped into the current process's address space
(e.g. via LoadLibrary).  So probably your process has already loaded
user32.dll, but not shell32.dll.
