basic problem about atl
-
When I create an ATL project with appWizard in vs2005, the Dll generated by the code contains four export functions. They are : DllCanUnloadNow PRIVATE DllGetClassObject PRIVATE DllRegisterServer PRIVATE DllUnregisterServer PRIVATE What are those functions for? And how to use them to implement the code? What's the differeces between this Dll and those normal ones(say win32 style dlls)? Seeking for help.

DllGetClassObjectis how other code creates COM objects that are implemented in the DLL.DllCanUnloadNowis called by COM to see whether the DLL can be unloaded from memory.DllRegister/UnregisterServerare used in self-registration, where the DLL adds/removes the registry entries needed for it to be visible to COM.
