A while back I created a DLL which uses Oracle OLE Objects for Oracle.
It used to compile just fine...
But I have now a new PC and reinstalled everything...

So I ask how do I resolve this link error:

Deleting intermediate files and output files for project 'dblink - Win32 Release'.
--------------------Configuration: dblink - Win32 Release--------------------
Compiling...
dblink.cpp
Linking...
   Creating library Release/dblink.lib and object Release/dblink.exp

Release/dblink.dll : fatal error LNK1120: 2 unresolved externals
Error executing link.exe.

dblink.dll - 3 error(s), 0 warning(s)

In the past I have found that C++ is very finicky when it comes to compiling things and projects are very hard to get working with just the c++ files.

Any advise...
Thanks
