Unable to connect to the remote server

[Antonello Calabrò]

Hi all,
I created a webservice that execute a sql query on demand.

If I try to execute the query from the WebForm, all is ok.
If I try to execute the query from a normal Windows
Application, all is ok.

The WebService run correctly.. but if I try to call the
Webservice from a SmartDeviceApplication the program crash
and the debug message is:
An unhandled exception of type 'System.Net.WebException'
occurred in System.Web.Services.dll
Additional information: Unable to connect to the remote server

And I have an error on the line marked with *** :


[System.Web.Services.Protocols.SoapDocumentMethodAt tribute("http://tempuri.org/productList",
RequestNamespace="http://tempuri.org/",
ResponseNamespace="http://tempuri.org/",
Use=System.Web.Services.Description.SoapBindingUse .Literal,
ParameterStyle=System.Web.Services.Protocols.SoapP arameterStyle.Wrapped)]
public string productList(string query) {
object[] results = this.Invoke("productList",
new object[] {
query});
*** return ((string)(results[0]));
}

Any idea? I start developing webservice from few time...
sorry if it's a noob question :)

Thanks in advance.

Hi Antonello,

This would happen if the query didn't return any results. The code you
showed is the client side proxy logic, correct? Note that you are using
the array element 0 without checking to see that any results came back.

I hope this helps
