c# - View Input Text for a second in TextBox and change to passwordchar -


It's the same but the last answer I wanted was I need c # wpf ... I tried the last answer but I Can not seem to get .. Sometimes the key can be pressed, and sometimes it is not. How can I get the same interval when press the key? 

  private Zero TextBox_KeyDown (Object Sender, KeyEventArgs E) {dispatcherTimer.Tick + = New EventHandler (dispatcherTimer_Tick); Sender Timer. Interval = New TimeSpain (0, 0, 0, 1); DispatcherTimer.Start (); }

I tried 

  Sender Timer Interval = timespan Foamseconds (5);

edit 

  Private Zero Dispatcher TimerType (Object Sender, EventArgs E) {string Str = ""; (Int i = 0; i & lt; txtPass.Text.Length; i ++) str + = char.ConvertFromUtf32 (8226); TxtPass.Text = str; TxtPass.Select (txtPass.Text.Length, 0); }

You do not need to subscribe to the new event handler each time. Just do it once in the constructor 

  dispatcher timer = new dispatch timer (); Sender Timer. Tick ​​+ = sender timer; Sender Timer. Interval = New TimeSpain (0, 0, 0, 1); In the   
  keydown  event, just reset  timer  (unfortunately we do not have any  reset  method ) 
   Private Zero Text Box / Kida (Object Sender, KeyEventArgs e) {dispatcherTimer.Stop (); DispatcherTimer.Start (); }

Just like the timer, just stop the stop the timer and do your work 

  zero sendimetric (object sender, event cargo e) {Dispatcher Timer. Stop (); // your code}
