call a web service

[Guest]

I am building a wireless application that runs in a window CE environment.
The wireless application will pass the barcode information to a web service.
It take a while for the wireless client to get back the result from the web
service. I also create a window application that has the same logic as the
wireless application and calls the same web service application. The window
application get the result back for the web service very quick. So the
bottleneck is the call between the wireless application and the web service.
Can anybody help me with some idea how to slove this problem?
thanks

Aside of the fact that wireless communications are slower, make sure that
your device has SP3 of Compact Framework.
Also keep in mind that unlike your desktop application that connects via
local network, the wireless one has to travel all the way around the
internet from the provider back to your server

If it happens only the first time do a blind call to webservice when you
launch the application (the first call to the webservice always takes
longer). If not quick enought create a client/server application directly on
the tcp/ip layer.
