c# Перехватываем любое окно в Windows и вводим в него текст или прячем

Передаем какой то текст в окно,как будто вводим с клавиатуры и жмем ОК кнопкой Enter:
int iHandle = Common.NativeWin32.FindWindow(null, "Сюда пишем заголовок нужного окна");
System.Windows.Forms.SendKeys.SendWait("Здесь пишем текст который нужно ввести в это окно");
//Жмем в окне Enter   

По аналогии прячем окно:
int iHandle = Common.NativeWin32.FindWindow(null, "Заголовок окна");
Common.NativeWin32.SetWindowPos(new IntPtr(iHandle), Common.NativeWin32.HWND.Top, 0, 0, 0, 0, Common.NativeWin32.SetWindowPosFlags.AsynchronousWindowPosition);
