    Endreceive when Formclosing is intiated

    Hi,

    I am programming a server-client socket software. On client side, when I click on the close window at the right upper side [X] Formclosing is initiated. I want to send to the server some information about disconnecting socket. My problem is that the client is in receiving state and I need to stop receiving state by calling socket.endreceive. I can't do that in Formclosing cause It need IASyncResult object that is not accessible.

    Is there a way to achieve that?

    many thanks.

    Patrice

    I feel/think you are misunderstanding the purpose of socket.endreceive.

    Try closing the socket in the Formclosing method. This will cause socket.endreceive to throw an ObjectDisposedException exception.
    Handle this exception in a try catch block.

    Thank you for the answer. I know what endreceive does. What I want to do is currently using endreceive to stop reading state and sending a message to the server side. But on FormClosing, I don't see how I can call endreceive without IaSync object.

    do you have any idea on what I can do?

    many thanks.
