Create a component in Visual Basic. Then add that component to MTS on the server. Once you have succesfully done that you can export the package from MTS. If you export it correctly, a .exe file will be created. Copy that file to all client machines and run it. Now the clients know where the component is located in the network and you can use it. (and thus DCOM is configured)

CJ

You need to create an ActiveX EXE project. When you use the Package and Deployment Wizard on it, it will prompt you, asking whether you want to include remote automation support files. A DCOM object must be in an EXE, not a DLL.

On the client, you'll need to use the second parameter of the CreateObject(obj,server) call.

CJ suggested MTS. I just want to clarify. You can use MTS or COM+ if you have it installed on the server, and it will be more efficient than DCOM. If you do, however, your project needs to be ActiveX DLL. You can not install an out of process ActiveX (ActiveX EXE) under MTS.

To CJ
as mentioned by u, i have run exe files on client machines.
but how to instantiate the object of the component registered on MTS server.
I have used CreateObject(object,servername) method.
here what will be the value of these two parameter.
will this method work?

CJ_SCommented:
You can do that the exact same way as you would normally do. However, the best way to instantiate the object is just by calling the CreateObject() function. Using the way I explained above you can ommit the second parameter.

Set myObject = CreateObject("DLLNAME.CLASSNAME")

You can also use the
Dim myObject as DLLNAME.CLASSNAME
or
Dim myObject as New DLLNAME.CLASSNAME

But the first approach is the best one.

Regards,
CJ
