What is DailyDilbert?

This code should give you an error since there is no class called
DailyDilbert defined here... or maybe it is defined beneath this code?

If such is the case, can you paste that code too?

My apologies...
DailyDilbert is a Web Reference to
http://www.esynaps.com/WebServices/DailyDiblert.asmx?WSDL
Thanks..

DailyDilbert

Excuse my previous email, just found out what DailyDlbert is. Do you have
a reference to it though? Am not seeing one

 

[deciacco]

That is the entire program.cs file...
The reference shows up under the Solution Explorer under "Web References".
The solution builds without any errors and runs, but nothing happends.
In debugging it looks like the "DailyDilbertImageCompleted_Handler" never
gets called.
Thanks

Hi, the file was not attached, yet in the meantime I came across this that
might help you

First, the URL you give for the web service has a typo inside. Make sure
that it's not the case in the actual web reference.

http://www.esynaps.com/WebServices/DailyDiblert.asmx?WSDL
instead of
http://www.esynaps.com/WebServices/DailyDilbert.asmx?WSDL

(BTW, if you're in touch with the web service creator, you should tell
him that using tempuri.org as a namespace is not recommended).

Then, you call an asynchronous web service in the "main" method of the
Console application. However, after the request is sent, the application
terminates (when main is finished, the application ends). When the web
service comes back, the application is finished already.

To solve this, you can either call the service synchronously (in which
case, the application waits for the response before ending), or you have
to wait for the response yourself. If you want my advice, since this
seems to be a test application only, use a WinForms application instead
of a Console app.

HTH,
Laurent

If however you want to keep your application a console application, you could define a global boolean variable (isFinished), and use this to keep the main thread alive (while(!isFinished) until the asynchronous operation has completed (inFinished = true).

On its own, that would be a bad thing (even if you remembered to make
it volatile); a far better option would be something like a
ManualResetEvent, or you can actually do the same thing with just
Monitor if you want.

An even better option... if you aren't going to do anything else, then
don't make it async... unless of course that is completely out of your
control.
