error while compiling soap client on vc++

[Rajendra <ra...@mahindrabt.com>]

    Hi All,
   While compiling following code for soap client on vc++ 6.0,
 Im getting following error "error C2871: 'MSSOAPLib' : does not exist or is
not a namespace".
 There are more errors. i think it's because of above error only.
 Im very new to vc++ and web services.
 Anybody if encountered same problem, pls let me know.
where do im making mistake or do i need to make any settings in vc++
environment.
 Thanks in advance,
 Rajendra.
