you need to register that DLL with windows using the REGSVR32 key and then refer that ddll from Project------> Reference menu of VB IDE.

Next you need to create objects of the class and call its objects.

Thanks for reply debasisdas,...How's that? how can I register my DLL using REGSVR32?

Anyweiz here's the DLL i make from C#:

using System;
using System.Collections.Generic;
using System.Text;

namespace MyDLL
{
    public class Class1
    {
        public int addnumbers(int a, int b)
        {
            return a + b;
        }
    }
}

I just need to call and use it in Visual Basic wherein I can Add numbers when I click a button!....

I've found it easyest to copy the dll to the system32 folder then run the below

get a command prompt (start run cmd)

type in
regsvr32 dllname

[debasisdas]

copy the dll to system32 folder and then from start----->RUN

execute the command REGSVR32 DLL filename

[umesh bet]

please send how download the regsvr required .dll file

[ImranQureshi]

its not to download from any where. REGSVR32 file is locataed at your windows drive (like c:\windows\system32\REGSVR32.exe) just you have to double click on dll file or right click and open with then select file from c:\windows\system32\REGSVR32.exe
after confirmation, your file is registered now.
and then refer that dll from Project------> Reference menu of VB IDE.
Next you need to create objects of the class and call its objects.

Enjoy

when i register the dll file using 'project --> references', i got this error message
"Can't add a reference to the specified file."
what's wrong?

Good grief. You're using a C# .NET DLL and trying to place it in VB6?

Maybe you're really trying to place a C or C++ .NET DLL and place it a Visual Basic 6 project? In which case, you're in the wrong forum. Go to the Visual Basic .NET forum.

I don't believe a C++ .NET DLL is compatible with VB6. I've tried this before and have had the same result as you posted: "Can't add a reference to the specified file."

You can create a DLL using the C or C++ programming language to use in VB6. But you have to follow the guidelines for working with VB6. I don't even know that you can create a C# DLL.
