VIRTUAL KEYBOARD IN C# FOR WINDOWS APPLICATION:

If you want to  enable virtual keyboard in our application, first we have to add a namespace

“using  System.Diagnostics;”

private void btnvirtual_Click(object sender, EventArgs e)

        {

            txtUserName.Focus(); //To place the cursor in textbox

            Process prc = Process.Start("OSK.exe");    

        }

 To Kill the Process without using window close button:

foreach (Process p in Process.GetProcessesByName ("Process Name"))

            {

                if (p.ProcessName.StartsWith("ProcessName"))

                    p.Kill();              

            }
