Webservices and codeunit instances

gvolkov · 2010-09-01

I have the following code:

public void SetService(object sender, EventArgs e)
        {
            MyCodeunit.MyCodeunit PLM = new CS.MyCodeunit.Management();
            PLM.Credentials = new NetworkCredential(GlobalClass.AppSettings["NAV2009USER"], GlobalClass.AppSettings["NAV2009PASSWORD"]);
            PLM.Url = GlobalClass.AppSettings["NAV2009WEBSERVICE"] + "Codeunit/Management";
        }

        public void button1_Click(object sender, EventArgs e)
        {
             
            Reply.Text = PLM.ParseCommand(Input.Text);
        }

and i am getting the following error:
The name 'PLM' does not exist in the current context

this must be something stupid, cause if i put the Reply.Text = PLM.ParseCommand(Input.Text); line into the SetService function, it works fine. But i only want to initialize the webservice once. not every time i click the button.

Thanks

I figured this one out. But now there is another question.

it looks like the my codeunit does not retain any values. for example:

i call the function, i get the response. i call another function, and it looks like i never called the first function.
Does the server create new instance of codeunit every time a function is called?

Each call of WS is independent and data between calls are not persistent, only if you write them into some tables. There are no singleinstance codeunits for using with WS...

Howdy, Stranger!
