This is part of my assembly:
[assembly: ComVisible(true)]
[assembly: ClassInterfaceAttribute(ClassInterfaceType.None)]
// The following GUID is for the ID of the typelib if this project is
exposed to COM
[assembly: Guid("cd099def-f9fb-407f-b793-9db68f6b8a0b")]
This is my code:
using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
using System.Globalization;
namespace ExtraStuff
{
[Guid("4E3BBC1B-625F-47bf-BE80-DAB84F1934BE"),
InterfaceType(ComInterfaceType.InterfaceIsIDispatc h),
ComVisible(true)]
public interface IExtraStuff
{
[DispId(1)]
double F2C(double val);
}
[Guid("F88DAD68-578A-4e23-BCFF-0FBBEC1C4B55"),
ClassInterface(ClassInterfaceType.None),
ComSourceInterfaces(typeof(IExtraStuff)),
ComVisible(true)]
public class ExtraStuffClass : IExtraStuff
{
public ExtraStuffClass()
{
}
public double F2C(double val)
{
return ((5.0/9.0) * (val - 32.0));
}
}
}
and excel vb code:
Option Explicit
Public Function F2C(val As Double) As Double
Dim ccw As ExtraStuff.IExtraStuff
Set ccw = New ExtraStuffClass
F2C = ccw.F2C(val)
End Function
I put my dll to C:\Program Files\Microsoft Office\OFFICE11\ and I registered
that by:
regasm /tlb /codebase ExtraStuff.dll
And when I'm trying use it I get error:
'Run-time error '-2147024894 (80070002)'
In oleview.exe raport everything seems to be OK. Can anyone solve my problem
?
