private void button1_Click(object sender, EventArgs e) { 
     Process[] plist = Process.GetProcesses(); 

     foreach (Process p in plist) { 
      if (p.ProcessName == "notepad") { 

       AutomationElement ae = AutomationElement.FromHandle(p.MainWindowHandle); 

       AutomationElement npEdit = ae.FindFirst(TreeScope.Descendants, new PropertyCondition(AutomationElement.ClassNameProperty, "Edit")); 

       TextPattern tp = npEdit.GetCurrentPattern(TextPattern.Pattern) as TextPattern; 

       TextPatternRange[] trs; 

       if (tp.SupportedTextSelection == SupportedTextSelection.None) { 
        return; 
       } 
       else { 
        trs = tp.GetSelection(); 
        lblSelectedText.Text = trs[0].GetText(-1); 
       } 
      } 
     } 
    }
