help with listbox/method/loop
Nov 24 2010 5:56 AM
Hi All,
I'm nearing the completion of a customized taskmanager, but running into a little problem
The following code fills a listbox with processes:
-------------------------------------------------------------------
private void Getprocs()
{
procs = Process.GetProcesses();
if (Convert.ToInt32(label2.Text) != procs.Length)
{
listBox1.Items.Clear();
for (int i = 0; i < procs.Length; i++)
{
if (procs[i].MainWindowTitle != "")
{
listBox1.Items.Add(procs[i].MainWindowTitle);
}
else
{
}
}
label2.Text = procs.Length.ToString();
}
}
---------------------------------------------------------------------
And then this method is used to kill the selected process:
-----------------------------------------------------------------------
private void button1_Click(object sender, EventArgs e)
{
try
{
procs[listBox1.SelectedIndex].Kill();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
-----------------------------------------------------------------------
When selecting and killing a process I get a "Access Denied" Messagebox..
However...
Excluding the if/else (procs[i].MainWindowTitle != "") code from the Getproc() method, so that is looks like below, kills a selected process just fine !
-------------------------------------------------------------------------
private void Getprocs()
{
procs = Process.GetProcesses();
if (Convert.ToInt32(label2.Text) != procs.Length)
{
listBox1.Items.Clear();
for (int i = 0; i < procs.Length; i++)
{
listBox1.Items.Add(procs[i].MainWindowTitle);
}
label2.Text = procs.Length.ToString();
}
}
--------------------------------------------------------------------------
Can anyone please help with this one ?
Thanks a lot !
