exception unhandled

with Visual studio 2005.
Code below.
add the client I added a webreference as you see. If I test the webservice in my browser it works, but not from the pda.

ERROR:

at runtime: Web exception was unhandled. Error cannot be displayed because an optional source-assembly was not found.
System.Net.WebException was unhandled
Message="Web exception was unhandled. Error cannot be displayed because an optional source-assembly was not found"

Below you can see the code: I test it with hard coded values on the server. Strange is that if I press ctr+F5 and consume the webreference from http. It works. The query is inserted in the database. Afterward i delete the value in the database to retest
When I call it from pda I get the upper exception. I even don't pass parameters. I do but I don't use because it's hardcoded at the server.
I'm searching now already for a while :s

pda   client:

             local.Service test = new DeKangoeroe.local.Service();
          Database databank = new Database();
            string transactie = databank.maakQuery("select * from code");
            MessageBox.Show(transactie);
          //this shows a well formed query(:start transaction; insert statement1;insert statement2;commit)
           //calling the service now
            test.ReceiveChangesFromRemoteSystem("uid", "pwd", transactie);
//are the objects not serialised

web service: service.cs
If I press control
[WebMethod]
    public string ReceiveChangesFromRemoteSystem(string remoteUserId, string         remotePassword, string sqlTransaction)
    {
        MySQLserver databank = new MySQLserver();
       databank.ExecuteCommand("insert into test values (\'koekoek\')","user", "pasword")
//As you see: hard coded, with the browser (local, pda) it works
    }

Hi yvading1482,

The exception you get is a very general one. You can not really undestand what is wrong from reading the exception. So lets try to undestand it together.

Let's try to create a simple "Hello world" web method. Try to consume it.

Let me know if it works.

If it does not work, i would try openning a new project and try again.

Let me know how you are doing.

Another way to debug is:

[WebMethod]
public string ReceiveChangesFromRemoteSystem(string remoteUserId, string remotePassword, string sqlTransaction)
{

try

{
MySQLserver databank = new MySQLserver();
databank.ExecuteCommand("insert into test values (\'koekoek\')","user", "pasword")

}

catch(Exception ex)

{

string msg = ex.Message;

throw new SoapException(msg);

}
}

OMG,

now it works.

I told you before, it was working on the pda from the browser, because there I was aware that I had to type the ip address of my pc.

On the computer I added a webreference from localhost

Normal people should take a gun and say, why can I be so stupid

I will hold my fingers cross for you

okay, I didn't try it on IIS 5.1 yet, but instead I tested it with the integrated ASP.net development server by opening two instances of visual studio(one for web services and another for deploying to PDA and retrieving the web services. Even if I make a new service and use the standard helloworld webmethod in my client, I get the same error :s

localhost.Service test= new DeKangoeroe.localhost.Service();
MessageBox.Show(test.HelloWorld());

Now I'll try with firewalls off, but normal this could not be the problem because soap is developped to pass firewalls (what RPC services couldn't)

I had positive tests with windows appplication, and web services on apache server.
It has to be something with the pda.
As you remember, consuming webservices by browser was possible.
Not from application
Nirvana Pine
update: if I consume the webservices with the pda browser, it also works.

But not by calling it from the application with the code above, while nothing has to be passed to let the webservice work, because for testing I coded everything hard. There must be something with the soap,xml, connection,...

I'm new to this.

this was my next step in debugging ;) My first was trying consume services with the browser of the pda.
I'll let you know the result. but first I'm studying for school

I'll try tonight with IIS, I think that apache hasn't the possibilies yet of processing soap messages.
If this is the reason it didn't work for 2 days
two days wasted:/

I tried with apache 2.0.55 and asp_mod. With the http protocol no problems. Let's hope it works tonight.
