Reply To: Organizing Code with Classes

[Support 3]

As you probably know, in VBS, you can create Class to defines an object, its properties and methods to control the object’s behavior. Please see the Visual Basic Script Guide for more information. You can access the guide from the Formativ Help menu.

The example code below create a class when then Applet start. The class object is destroyed at the end so you can use it in throughout the Applet (i.e. Form events, etc).

  
dim gMyClass

'-------------------------------------------------------------------------------
' Main line processing
'-------------------------------------------------------------------------------

Sub Main(Client, GWEvent)

  set gMyClass = new CMyClass


  msgbox "Inside Main sub: " & gMyClass.DateTime
  gMyClass.UpdateDateTime()
  msgbox "Inside Main sub: " & gMyClass.DateTime


  MyDialog.showmodal

  set gMyClass = nothing
  
End Sub


'================================================================================
' Description about my class
'================================================================================
class CMyClass

  private iDateTime


  ' Constructor
  private sub class_initialize
    iDateTime =  now
  end sub


  ' Destructor
  private sub class_terminate

  end sub


  ' Update date time
  public sub UpdateDateTime()
    iDateTime =  now
  end sub


  public property get DateTime()
    DateTime = iDateTime
  end property


  public property let DateTime(aVal)
    iDateTime = aVal
  end property

end class


'================================================================================
' On button click in the form
'================================================================================
Sub MyDialogButton1Click(Sender)
  msgbox "on button click: " & gMyClass.DateTime
  gMyClass.UpdateDateTime()
  msgbox "on button click: " & gMyClass.DateTime
End Sub

Hope I haven’t misunderstood your enquiry.
