This will send "A" to notepad:

[DllImport("User32.dll")]

public static extern Int32 SendMessage(

IntPtr hWnd,

int Msg,

int wParam,

[MarshalAs(UnmanagedType.LPStr)] string lParam);

[DllImport("user32.dll", SetLastError = true)]

public static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

[DllImport("user32.dll", SetLastError = true)]

public static extern IntPtr FindWindowEx(IntPtr hwndParent, IntPtr hwndChildAfter, string lpszClass,

string lpszWindow);

private void Form1_Load(object sender, EventArgs e)

{

var notepad = FindWindow("notepad", null);

var edit = FindWindowEx(notepad, IntPtr.Zero, "edit", null);

SendMessage(edit, 0x000C, 0, "A");

}
