This utility class offers three methods to dispatch keypresses to the active application.

Send() sends a string of keystrokes. Nonprintable keys are represented by a series of special character codes between curly braces (for example Page Down is {PGDN}).

Flush() pumps messages until the keys have all been sent. SendWait() sends the keystrokes and pumps messages until all the keys have been sent. It is equivalent to Send( ) followed by Flush().

public class SendKeys {
// Public Static Methods
   public static void Flush();
   public static void Send(string keys);
   public static void SendWait(string keys);
