[VB.Net] Handling multiple processes at once, using for each and arrays - The-One - Dec 11, 2010

Hello,

In this tutorial I will explain you how you can kill(you can do whatever you want, but i'll be using kill) multiple processes at once.

I'll be using:

- one Listview
- one Contextmenustrip

Okey,

First draw the items into the form.

Then, on top, under Public Class Form1 add:

Code 
Dim countitems As Integer = 0

Then in Form1_Load paste:

Code 
For Each p As Process In Process.GetProcesses

    Dim lviList As New ListViewItem(New String() {p.ProcessName.ToString}) ' create a new line

    ListView1.Items.Add(lviList) 'add it

    countitems = countitems + 1

  Next

Click the contextmenu you previously added and add a new item name it Termiate (or whatever you want).
Okey, go into the designer, select the listview.

Set the next settings:

CheckBoxes = True(To put checkboxes infront of the items, you can use multiselect (Hit Ctrl and select multiple items, but I prefer checkboxes))
View = Details
ContextMenuStrip = ContextMenuStrip1(So where ever you right click (inside the listview ofcourse), the contextmenustrip will appear)

Add the following code to the contextmenu item.

Code 
Dim index As Integer = 0 ' count

  Dim str(0 To countitems) As String ' Max

  Array.Clear(str, str.GetLowerBound(0), str.Length) ' clear the array

  For Each lvi As ListViewItem In ListView1.CheckedItems ' for each checkbox checked

    str(index) = lvi.Text ' set array

    index = index + 1 ' index + 1 for next array

  Next

  For Each p As Process In Process.GetProcesses

    For i = 0 To index - 1 ' Loop through all process strings we want to kill

    If p.ProcessName.Contains(str(i)) Then ' if its equal

    p.Kill() ' kill it

    End If

    Next

  Next

You can use multiselect to, you just have to change:

Code 
For Each lvi As ListViewItem In ListView1.CheckedItems

into

Code 
For Each lvi As ListViewItem In ListView1.SelectedItems

and ofcourse, leave the checkboxes out.

Press F5 and check it out.

Fully programmed and wrote by me, reply's are welcome :)

I was just pointing it out. Back when i started programming i learned variable basics before Process.GetProcesses Method.

Lol you are comparing variables with processes? Like comparing a dog with a cupcake.

I can see the point went straight over your head. Should of guessed it really.
