I have an ATL 7 web service.  I need to call methods in an MFC extension
DLL.
I have wrapped the extension DLL with a 'normal' (_USERDLL) MFC dll and
linked my web service to the normal DLL.  There is code in the
InitInstance() of the MFC application in the 'normal' DLL which calls the
initialisation code of the extension DLL (so that MFC resources etc are
correctly located).

When I try to call the web service the LoadLibrary() is failing with the
error 1114 (ERROR_DLL_INIT_FAILED).

I am using Visual Studio project dependencies to link the various DLLs.
That is to say I have a solution with the ATL web service, a normal MFC dll
that has an instance of CWinApp and an MFC extension DLL that has and
exported initXXX method.  I have set the solution dependanies such that my
web service depends on the normal MFC dll and the normal MFC dll depends on
the extension DLL.

My questions are:

1) Is loading an MFC dll from a ATL server 7 web service dll a valid thing
to do?  If not, why not?

2) Assuming that the answer to 1) is 'yes', and the MFC dll that you load
needs to use an MFC extension DLL, are there any special considerations that
need to be taken into account when initialising either the MFC DLL or the
MFC extension dll?

3) Assuming the answer to 2) is 'no' - any other ideas why my web service
DLL fails to load?  If I remove the links to the MFC DLL's it loads and runs
just fine.

TIA
