vb.net - User-defined class always returns 0 -


I have a simple program, but I can not return this square to the area of ​​a rectangle; It always returns to 0, including class variables. I can not get this zodiac thing to work for life. Here's the main form: 

  Personal category btnCalc_Click (Sender as object, and sender as EventArgs) handles btnCalc.High handle as new rectangle as 'dim strlength string' As the dim strWidth string double. Trips (TSTLextext, rectic lalent) double. Trypsers (TCTADAd.Text, Rect.Wide) 'Strongable = Inputbox ("Please input the length of the rectangle", "Calculate Area")' Double. Tryi purse (strileth, rect.Length) 'strWidth = InputBox ("Please input the width of the rectangle", "Count the area")' double. Trips (Stroydith, Ritch Width) LLLERIA Text = rectangle Getre The toasting and sub-class   
 and here's the square  
  public square rectangle _dblLength double _dblWidth as double private double as public property length Go back as time goes _dblLength set to go (double as value) if value & gt; 0 then _dblLength = value Else _dblLength = 0 termination if termination property is terminated. Return the width of the asset of the property double as the return _dblWidth set (double as the value) if the value & gt; 0 then _dblLength = value Else _dblLength = 0 end if end set end property "When you make a new call primarily, it generates variable, public sub new () _dblLength = 0 _dblWidth = 0 and public function GetArea ( ) Double return as _dblLength * _dblWidth End Function End Class    
 
 
 Your  Width  Property: This setting is  _dblLength  but returning to  _dblWidth .  
  _dblWidth  will always be zero, so your count area will always be zero.
