This article is about the processes in your
computer & operations on them.
You can use the Process class in the System.Diagnosis namespace.
using
System.Diagnostics;
Using the Process.GetProcesses() method it will get all the processes in
your computer as an array of Processes....
Process[]
prc=Process.GetProcesses();
Every time it will first clear the ListBox otherwise it will append the
processes to the ListBox. So we need to clear the ListBox before adding the
processes in the ListBox.
lbProcess.Items.Clear();
Now I create one process called Load_Process & it will load all the processes currently running in the computer and display them in the ListBox.
private void Load_Process()
{
lbProcess.Items.Clear();
try
{
foreach (var item
in prc)
{
lbProcess.Items.Add(item.ProcessName);
}
}
catch (Exception e)
{
MessageBox.Show(e.Message.ToString());
}
}
See The following Image
When the user clicks on the refresh button it
will load all the process again into the ListBox.
private void btnRefresh_Click(object
sender, EventArgs e)
{
Load_Process();
}
After selecting a particular process it will kill that selected particular
process from the list & then again it will load all the processes in the ListBox.
private void btnEndTask_Click(object
sender, EventArgs e)
{
if (MessageBox.Show("Are
You Sure Want To Kill..?", "Kill Process",
MessageBoxButtons.OK) == System.Windows.Forms.DialogResult.OK)
{
prc[lbProcess.SelectedIndex].Kill();
lbProcess.SelectedIndex = 0;
Load_Process();
}
See the Following Image
If the user wants to add a new task then by clicking the
NewTask button it will start the new process & then it will load all the
processes into ListBox, so that it will add that new process in the list.
private void btnNewTask_Click(object
sender, EventArgs e)
{
OpenFileDialog ofd = new
OpenFileDialog();
ofd.ShowDialog();
Process.Start(ofd.FileName.ToString());
Load_Process();
}
See the Following Image :
After adding the new task in the list it will
display in the ListBox process.
See the Following Image :
If the user wants to find a particular process from the
list then it will find that specific process name from the list & if it will find
then it will select that process in the ListBox.
You can find the process name as simple search using FindString method &
find Exact match using FindStringExact method.
private void btnFind_Click(object
sender, EventArgs e)
{
if (cbFindExact.Checked)
{
for (int
i = 0; i < lbProcess.Items.Count; i++)
{
if (!(lbProcess.FindStringExact(txtFind.Text)
== -1))
{
lbProcess.SelectedIndex =
lbProcess.FindStringExact(txtFind.Text);
break;
}
else
{
MessageBox.Show("No Process In
List....");
break;
}
}
}
else
{
for (int
i = 0; i < lbProcess.Items.Count; i++)
{
if (!(lbProcess.FindString(txtFind.Text)
== -1))
{
lbProcess.SelectedIndex =
lbProcess.FindString(txtFind.Text);
break;
}
else
{
MessageBox.Show("No Process In
List....");
break;
}
}
}
}
See the following Image of Simple Search :
See the following Image Of Find Exact Match :
If the process does not find an exact match then it will
display the error message to user.
See following Image :
This way you can perform all these operations
of processes...
