All of us kNow there are so many services running in background without our kNowledge. We can view,what are the services running on our system by typing services.msc in Run of Start Button.
I will explain how to create a Web Application to manage the services running on our system. This application allows us to see all services present in our system. We can also start,stop,or pause the services. This application will show some details of all services,like its path,state... I created this application in VS.NET 2003.
First create a web application in VB.NET and Name it as ServiceMgmt.
Design the UI as shown below:
There are 4 linkbuttons,one dropdownlistand 7 labels in it.
Add reference to System.Management(in Solution Explorer) as shown below:
Next,
Add this code in Page_Load :
Dim class1 As ManagementClass = New ManagementClass("Win32_Service")
For Each ob As ManagementObject In class1.GetInstances
Dim item1 As ListItem = New ListItem
item1.Text = ob.GetPropertyValue("Name").ToString
item1.Value = ob.GetPropertyValue("Caption").ToString
DropDownList1.Items.Add(item1)
Next
This will load all the services into the ComboBox.
Next add this method:
Private Sub showstatus()
Dim i As Integer = 0
Dim class1 As ManagementClass = New ManagementClass("Win32_Service")
For Each ob As ManagementObject In class1.GetInstances
If ob.GetPropertyValue("State").ToString = "Running" Then
System.Math.Min(System.Threading.Interlocked.Increment(i),i - 1)
End If
If ob.GetPropertyValue("Name").ToString = DropDownList1.SelectedItem.Text.ToString Then
Label2.Text = "Description : " + ob.GetPropertyValue("Description")
Label3.Text = "PathName : " + ob.GetPropertyValue("PathName")
Label4.Text = "ServiceType : " + ob.GetPropertyValue("ServiceType")
Label5.Text = "StartMode : " + ob.GetPropertyValue("StartMode")
Label6.Text = "State : " + ob.GetPropertyValue("State")
End If
Next
Label7.Text = String.Empty
Label7.Text = "Total Number of Services Running : " + i
End Sub
This will be called whenever you select a service from comboBox. This will show some of the details of the service.
Next add this method:
Private Sub servicemgmt(ByVal status As String)
Dim path As ManagementPath = New ManagementPath
path.Server = System.Environment.MachineName
path.NamespacePath = "root/CIMV2"
path.RelativePath = "Win32_service.Name='" + DropDownList1.SelectedItem.Text.ToString + "'"
Dim service As ManagementObject = New ManagementObject(path)
Dim temp As ManagementBaSEObject = service.InvokeMethod(status,nothing,nothing)
End Sub
This method will start,pause,continue the service you selected from comboBox.Next copy this code to Start LinkButton_Click:
servicemgmt("StartService")
showstatus()
Next copy this code to Stop LinkButton_Click:
servicemgmt("StopService")
showstatus()
Next copy this code to Pause LinkButton_Click:
servicemgmt("PauseService")
showstatus()
Next copy this code to Continue LinkButton_Click:
servicemgmt("ResumeService")
showstatus()
I hope this code will be useful for all. Final screen will be like this:
