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); } } } }
