thank you solve my problem with this: If (txtstart.text="OK") { do somthing } else if (txtstart.text="Stop") { application.close(); }

Ok understand that. But now i have problem to call this voids in private void btnstart_Click(object sender, EventArgs e) { if (button1.Content = "Start") { } else { } } I get error:The type or namespace name 'RoutedEventArgs' could not be found (are you missing a using directive or an assembly reference?)

Hello How can i create one button for two events? For example: I want to have one button for start/stop. At the beginning of the application button name is start (start the event ), when I click the button second time it change the name to Stop (stop the event)???? I am very new to C# programming, i know to do this in VB6... Sorry for my bad english! ThankYou
