    Windows form App: listbox

    I have a windows form application in which I am trying to add a line to the listbox component from another object.

    The object is a socket object that connects, sends msgs.. etc.
    but I want to show the results of some functions of the socket object in the listbox of the windows form.

    If I create an instance of the socket object in the windows form, then how can I add new lines to the listbox?

    Would I have to pass an instance of the windows form and pass it to the socket object?

    Can't you just add the result?

    Code:
    int i = sock.Send( ... );
    listBox1.Items.Add("Result of send was " + i.ToString());

    I do all the socket related stuff in one object. The form has the the socket object and I have no way of passing an instance of the form object to the socket object since the socket object is used in the form object.

    So far I have beein trying to call a function like

    Code:
    void AddLine(String* line)
    {
        listbox1->Items->Add(line);
    }
    but since i have no way of getting an instance of the form object to the socket object, I am stumped.

    There's always a way....global variables, global functions, etc...
