I made a dll in C#.net with MS Visual C# 2005 Express Edition. When i declare the ActiveXObject it gives either of the two errors.

code:

---

Error: unknown.
       Line: 4. Code: -2147024894.

---

or

code:

---

Error: Automation server can't create object.
       Line: 4. Code: -2146827859.

-The dll is COM Visible
-The dll is registered with ResAsm utility and is also placed in <DotNetFiles> in the ScriptInfo.xml
-A GUID is registered.

I've read other threads on the forum, some of them having the same problem. But none have a working solution .

Any help is appreciated

Great thread. Same problem here.

Would you send me some c# code so I see if I'm doing something wrong there? I'm not even sure my dll is COM visible.

Sample code i'm using

code:

---

public string Return(string strString)
        {
            return strString;
        }

---

And to make an assembly COM visible in Visual C# 2005. Projects > Application > Assembly Information > Make Assembly COM Visible.

Thanks I'm trying some things here if I succeed I'll make sure to let you know

I can't exactly remember how i got my C# dlls to work, but theres another process you have to do to the actual code itself to get it "visible" and able to be registered. I'm fairly sure i learnt how to do it from a tutorial on the codeproject website.

Sorry, but i hope this helps .

Edit: Heres a .dll i made to use with Plus! live, having a look at the format you may beable to copy it and make your dll accessible.

The project name was "MPL".

code:

---

using System;
using System.Collections;
using System.Text;
using System.Runtime.InteropServices;

namespace CS
{
    [Guid("D6F88E95-8A27-4ae6-B6DE-0542A0FC7039")]
    [InterfaceType(ComInterfaceType.InterfaceIsIDispatch)]

    public interface _Functions
    {
        [DispId(1)]
        string DoSearch(string query, int resultsnum);
    }



    [Guid("13FE32AD-4BF8-495f-AB4D-6C61BD463EA4")]
    [ClassInterface(ClassInterfaceType.None)]
    [ProgId("MPL.Functions")]
    public class Functions : _Functions
    {
        public string DoSearch(string query, int resultsnum)
        {
            //example code
        }
    }
}

I'd personally recommend staying away from ActiveX dlls and use as much Jscript as you can.

If I make a dll out of that..

var msg = Interop.Call("c:\\Projects\\sendMsg\\teste.dll","DoSearch","feio",2);

Calling it like that...

Interop.Call failed to locate function "DoSearch"

is what I get.

thats for a COM dll though, Interop.Call is for dlls which export their functions.

you use the following for COM

code:

---

var obj = new ActiveXObject("name.id");

---

Ok that was it...
Thanks

Read many articles on The Code Project, none of them could help me to get rid of the unknown error .

why are you searching so specifically? why not search for something like "C# COM ActiveX Expose" or sometihng
