I’m using the following code within the JCProperty class to retrieve data from a DAL: 

Dim x As JCProperty         x = JCPropertyDB.GetProperty(PropertyID)          If Not x Is Nothing Then             Me.PropertyID = x.PropertyID             Me.AddressLine1 = x.AddressLine1             Me.AddressLine2 = x.AddressLine2             Me.AddressLine3 = x.AddressLine3             Me.AddressCity = x.AddressCity             Me.AddressCounty = x.AddressCounty             Me.AddressPostcode = x.AddressPostcode             Me.TelNo = x.TelNo             Me.UpdatedOn = x.UpdatedOn             Me.CreatedOn = x.CreatedOn             Me.Description = x.Description             Me.GUID = x.GUID         End If

This works fine but requires that the DAL object (JCPropertyDB) is aware of the business object (JCProperty) and I effectively create and populate the same object twice (once in the DAL to return to the BL and then again within the BL object to populate itself).

I’m missing something here, I know there must be a better way!

Effectively I need to assign ‘Me = x’ which is not allowed. Can someone put me straight?

  1. Personally, I’m lazy. I usually do something like:

    class JCProperty : inherits JCPropertyDB    {     New()       {       MyBase.New()        GetProperty(PropertyID)        }    }

    Then you’re basically done, until you have some additional functionality in the JCProperty class that needs to happen ‘on top’ of the functionality already existing in JCPropertyDB. Then you override the JCPropertyDB methods to call the base method first then add your new functionality.
