-- RegSvr32: LoadLibrary(".\Debug\MAPConnector.dll") failed. ".\Debug\MAPConnector.dll" is a relative path name. Maybe some other DLL used by your application is not in the path at the time RegSvr32 is being executed. Or else the current directory is not in the correct location relative to your path for RegSvr32 to find your DLL to load it to register it at the time you are doing the build. I seem to recall editing the project build settings and using a variable that represent the project directory, instead of an abolute relative path to the DLL. for exmaple "$(ProjDir)\Debug\MAPConnector.dll"

From my recent experiance, you can't properly impliment a singleton in a DLL; you have to use an .EXE. It's not all that hard - make a new ATL project with EXE (not server). Create a new ATL Simple Com object (MyCollection). Make it a singleton with the DECLARE_CLASSFACTORY_SINGLETON(CMyCollection) macro. Modify your STDAFX.H generated file and change _ATL_APARTMENT_THREADED to _ATL_FREE_THREADED. You're good to go. Register it. Import your generated .TLB to make the smart pointers and whatever. I suggest using something like this: MyServerApp::IMySingletonPtr iSingle("MyServerApp.MySingleton") for each use, since it's very possible for the user to kill the process. Word of warning: once the last usage of your singleton (addref/release) is released, if there is no activity for 5 seconds, then it will be destroyed. If this is a problem, then either use connection points or some other refernce mechanisim.
