Hi,

We are using VB.net for developing the windown application. Using webservices for updating and fetching the data to the server. It works fine as we are using this setup for quite some time. Now we are in to one big form where i need to take 50 inputs. with this the webservices raises a exception which i put down. can anyone faced the same problem and can suggest soemthing. Webservice works fine for all the input forms except this big one.

Thanks in advance
