Simple(?) web service

[VK]

Hello:

I have written a simple web service which just is NOT deploying to
client.

The web service is an sp, and ws returns a data set.

On the client project, I have added a reference to this web service. How
to retrieve this dataset set into the client project? I have set up a
datagrid but the nothing seems to work.

Thanks for your help in advance.

Hi,
if ws returns a DataSet, from client's perpective, IT IS THE DataSet itself,
so treat it as ds, retrieving rows, fields and whatever you do with a ds,
icluded being DataSource for whatever control. However, AFAIK, each call to
DS means a call to WebService; so I create my own ds in the client app,
serialize webservice (writing XML) and then load my local ds (reading XML)
and every subsequent op is done via this local ds. Does this make sense?

No. The DS is serialized, sent across and a local instance created. Any calls to the dataset are
local.

You are just copying and taking a lot more code to do what webservices already do for you.

Thanks, Kudzu, 4 your reply.
Actually, I need explicit serialization in case clients can't get connected,
so they can inquiry previous result sets. However, now I reload ds only if
disconnected, and all goes much faster. Have a nice day!

Even then you can tell the datasets to serialize on their own. There are some really easy examples

Thank you, Kudzu, for your advice;
however, I wasn't able to find a ref; where should I search in?

See the parts where it saves the datasets, etc... You can download the projects and play with them
too. It puts htem in a file, but you can do same to a stream.
