FW: Loading DLL from Web Service

As per an earlier suggestion in the [email protected], I have
the following code in my XML web service:



    [DllImport (@"c:\inetpub\heintze\AnalyzeResults\CaseAssessment.dll",
CallingConvention=CallingConvention.Cdecl)] public static extern double
addr_(  ref  double   X, ref  double   Y  );

    [WebMethod] public double addr (   ref  double   X, ref  double   Y   ){

      return addr_(  ref  X, ref  Y  );

    }



This function addr_ just adds two numbers. It works when I call it from a
console mode test client. (I'm using ref here because the C code for
addr_was generated by a FORTRAN to C converted and FORTRAN likes to pass
EVERYTHING by ref).



As per a suggestion in the NNTP forums, I moved the DLL to the bin directory
created by visual studio.net. I checked the file protections for my DLL and
they are identical to the DLL deployed by Visual Studio.NET and I can access
that one.



Since I share this server with many other customers of the hosting service I
hired, I am not at liberty to put the DLL anywhere. I get the following
error when I access the service, I get the following error listed below. I
asked the hosting service to use Internet Service Manager to allow execute
permissions on the virtual directory I am in but this did not help.

 Thanks,

  Siegfried
