Answer 1

Regarding the compiler message - look at this link

 TextBox FailureText; - you declared a variable, but it is not initialized. you might set it to null / a value / default() - but you must initialize it
 TextBox UserName; - the same

when you call UserName.Text - the compiler alerts for the uninitialized UserName
