Introduction

When I was reading the MSDN.NET library, I found an interesting topic about windows services. So I tried to build an application by myself about windows service management. This idea comes from the service application that Microsoft has built in the control panel. I hope this application can be become useful.

Building the Application

To build this application I use ServiceController class. This class needs namespace System.ServiceProcess. You can check on your MSDN libary. Here's these steps:

1. New Application C#, specify WinServiceManage as the project name with Window Application (figure 1)

Figure 1

2. Add a Reference on your application, click menu Project -> Add Reference and choose System.ServiceProcess.dll

Figure 2

3. Build your GUI like figure 3

Windows forms:

• Label

• Button

• Panel

• ListView

Figure 3

Properties of ListView:

The following shows the properties of the ListView (click button ...). Add 4 column with property:

Figure 4

4. Add this line of code on the top of file form1.cs    

using System.ServiceProcess;

and add a variable on Form1 class

public <font >ServiceController[] services;</font>

5. This is the code when the "View All" button is clicked:

try
{
 ListViewItem datalist;
 services = ServiceController.GetServices();
 ServiceList.Items.Clear();
 foreach(ServiceController service in services)
 {
     datalist = new System.Windows.Forms.ListViewItem(service.ServiceName.ToString());
     datalist.SubItems.Add(service.DisplayName);
     datalist.SubItems.Add(service.Status.ToString());
     ServiceList.Items.Add(datalist);
 }

}
catch(Exception er)
{
 MessageBox.Show(er.Message,"Error Exception",MessageBoxButtons.OK,
                       MessageBoxIcon.Error);
}

6. Add Method with right mouse clicking on class view. Method name is List

Figure 5

Figure 6

Here's the code:

public void ListChange()
{
  if(ServiceList.SelectedItems.Count!=0)
  {
      ListViewItem item = ServiceList.FocusedItem;
      if(item!=null)
      {
          if(item.SubItems[2].Text=="Running")
          {
              StartBtn.Enabled = false;
              StopBtn.Enabled = true;
          }
          else
          {
              StartBtn.Enabled = true;
              StopBtn.Enabled = false;
          }
      }
  }
}

7. Method on Event of ListView ie: Click, KeyDown, and KeyUp

ListChange();

8. The code line when start button is clicked:

private void StopBtn_Click(object sender, System.EventArgs e)
{

   try
   {
       if(ServiceList.SelectedItems.Count!=0)
       {
           int n = ServiceList.FocusedItem.Index;
           if(services[n].CanStop)
           {
               services[n].Stop();
               StartBtn.Enabled = true;
               StopBtn.Enabled = false;
               ServiceList.FocusedItem.SubItems[2].Text = "Stopped";
           }
           else
           {
               MessageBox.Show("This service couldn't be stopped","Error",
                               MessageBoxButtons.OK, MessageBoxIcon.Error);
           }
       }
       else
       {
           MessageBox.Show("Please,choose a service that you want to stop",
                           "Information",MessageBoxButtons.OK,
                           MessageBoxIcon.Information);
       }
   }
   catch(Exception er)
   {
       MessageBox.Show(er.Message,"Error Exception",MessageBoxButtons.OK,
                       MessageBoxIcon.Error);
   }
}

9. The code line when stop button is clicked:

private void StartBtn_Click(object sender, System.EventArgs e)
{
  try
  {
      if(ServiceList.SelectedItems.Count!=0)
      {
          int n = ServiceList.FocusedItem.Index;
          services[n].Start();
          StartBtn.Enabled = false;
          StopBtn.Enabled = true;
          ServiceList.FocusedItem.SubItems[2].Text = "Running";
      }
      else
      {
          MessageBox.Show("Please,choose a service that you want to stop",
                          "Information",MessageBoxButtons.OK,
                          MessageBoxIcon.Information);
      }
  }
  catch(Exception er)
  {
      MessageBox.Show(er.Message,"Error Exception",MessageBoxButtons.OK,
                      MessageBoxIcon.Error);
  }
}
