increasing time out

Question

Hi, i'm adding web reference of my ASP.net web service to my application. and using that object to call web methods. web method has some logic that takes some time to execute(getting data from some application etc). but call to web method returns unsuccesfull on client side. i.e. HRESULT returns unsuccesful. when i debug the application and web service method, i found that, function call returns before execution on web service end finishes. i tried incresing socket time out value ,but doesn't helps. is there any way around. thanks, prasad
