I guess that you are talking of a COM-DLL and the #import directive. In this case you can use the rename attribute. If the COM-DLL already provides a namespace the attribute rename-namespace may be useful, too.

But sir The main thing how can i know about the namespace the dll provide ?

If I remember correctly, the default namespace matches the name of the library. Use the "OLE/COM Object Viewer" (you find it in the Tools menu of Visual Studio), browse to the according Type Library and open it. Somewhere you will find something like:

[
...
]
library SERVERLib
{
...
}

In this case SERVERLib will be the default namespace.
