Hi Sunil,
I’m not very familiar with C++. However, you can think about to build a
small .NET application to upload file. That will be easy for processing the
file on server-side. And it is not difficult to call the .NET program from
your C++ application.
Or you can make .NET component to perform upload file function, then call
the .NET component from COM
(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnbda/html/cominterop.asp).
