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 ServiceController[] services;

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);
    }
  }
