I am trying to learn ATL&COM using a book named "ATL Developer's Guide"
The chapter two has a project.
The code like this .

; Server.def : Declares the module parameters for the DLL.
;
LIBRARY      "SERVER"
DESCRIPTION  'SERVER Windows Dynamic Link Library'
EXPORTS
    ; Explicit exports can go here
    DllGetClassObject   PRIVATE
    DllCanUnloadNow     PRIVATE
    DllRegisterServer   PRIVATE

I had registered the dll successfully. But When I try to unregister it , the exception tell me
"The module E:\Server.dll was loaded but the entry-point DllUnregisterServer was not found.Make sure that E:\Server.dll is a valid DLL or OCX file and then try again "

I already used OleView checking the dll .
How can i unregister the dll?
thanks.

I notice this message "Your DLL must implement DllRegisterServer and DllUnregisterServer".It's mean that i can't unregister the dll,isn't?

Yes, it is: if your DLL doesn't implement DllUnregisterServer then the only way to unregister it is to know all the entries in the Windows registry that you should manually remove (and it is a nightmare).
Since you have the source code, the best is to add the DllUnregisterServer to your library, compile it again and then call regsvr32 /r filename.dll
