Very Computer

I am trying to create an interface that passes the ADO interface _Recordset
as an out parameter.  However, every attempt I have made fails.  Below is my
IDL file.  I have been trying two different methods.  The first is to use
importlib on the DLL, which seems to be the correct way.  However I get the
following error when I do this -

.\junk.idl(41) : warning MIDL2039 : interface does not conform to
[oleautomation] attribute : [ Parameter 'pVal' of Procedure 'GetResult'
 Interface 'IDA' ) ]
MIDL error 0xc0000005: unexpected compiler problem. Try to find a work
around.

The other thing I have tried, which is commented out right now, is to use
OleView.exe to get the IDL code and add that to my project using the import
directive.  However, when I do that I get this error -

Processing .\msado.idl
msado.idl
MIDL error 0xc0000005: unexpected compiler problem. Try to find a work
around.
Error executing c:\winnt\system32\cmd.exe.

Does anyone have any ideas on how I can accomplish this task?

I got the same message a while back.

The remedy is ........

Turn off compiler optimizations.  That worked for me.  Hopefully it will
work for you.
