I am using .VS.NET 2003.
code is pretty simple.
1. Created new c# project and it loaded default form "Form1"
2. I added listbox with default name listBox1
3.Added double click event
4. Added one line of code in that event
this.Close()
When i double clicked on listbox everything works fine. Form closed properly
without any errors.

Can you provide me the code for what your tried? And, what version of
..NET you are running? Thanks

Joe,
I tried a sample like you described. Form closes properly after
doubleclick in listbox. No issues at all.

news:C2**********************************@microsof t.com... I am using VS.NET 2003 and am having an interesting issue with a
Listbox control. Essentially, I have a form with a listbox on it. In the
listbox doubleclick event I would like to do some processing and then close the
form. However, I receive an error (Cannot access a disposed object
named "ListBox".) after my doubleclick code has processed.
/* ***************************
private void listBox1_DoubleClick(object sender, System.EventArgs e)
{
this.Close();
}
****************************/
To reproduce, create a form, drop a listbox on it, assign the
doubleclick event and put "this.Close();" in the handler. Does anyone know if there
is a fix to this issue? There are workarounds, best I've seen so far is: /****************************
private void listBox1_DoubleClick(object sender, System.EventArgs e)
{
this.BeginInvoke( new EventHandler( CloseForm ) );
}
private void CloseForm( Object sender, EventArgs e )
{
this.Close();
}
***********************************/
I think this must be an error in how the message processing is handled
within the list box control itself?
Thanks,
Joe
