What does rundll32.exe do

[aclayborne]

What does rundll32.exe do and what type of dlls work with it. I have a SDK that requires me to register the dll's with this command:
("RUNDLL32.EXE xxxx.DLL,Install /NOUI", 1)
The OCX file associated with the dll won't run properly if I simply try to register the dlls.
Is there anyway to access the code in xxx.DLL so I can see what actually being done.

rundll32 will actually run the DLL. Meaning the only sub in the DLL being run will be "Initialize". They probably have code in there to register, move files, install and etc.

No once a DLL is compiled it is just like an EXE. Just binary data, there is no way to un-compile it. Craig, mailto:sander@cogeco.ca
