Creating your own class definition with the traditional ASP

Creating your own class definition with the traditional ASP To follow the steps on this article you need at least Microsoft Windows 9x and IIS installed. This time we will learn and take a closer look at one of the traditional ASP?s feature, it is the ability to accept coder?s class definition. Long before the release of the .NET framework, this feature remains hidden for most of the coders, including myself. If you already familiar with Visual basic, you won?t find any difficulties implementing this feature into your web application since the structure needed to assemble an ASP class is quite similar to the class structure within the Visual Basic.

OK, lets get into it. Below is a simple class definition example created with traditional ASP, named MotorBike.

Class MotorBike
Private x_MBikeMake

Public Property Get Make()
Make = x_MBikeMake
End Property

Public Property Let Make(z_Make)
x_MBikeMake = z_Make
End Property

Private x_MBikeModel

Public Property Get Model()
Model = x_MBikeModel
End Property

Public Property Let Model(z_Model)
x_MBikeModel = z_Model
End Property

Public Sub Combine()
response.write Make & ” : “ & Model
End Sub
End Class

On the example above, MotorBike Class consists of two private members (the Bike manufacturer and the bike model), four public properties (2 get, 2 set), and a Sub Procedure (combining the bike manufacturer and the bike model).

To use it on your ASP page, add the code below under the class definition, then save it as motor.asp,

Dim objMotorBike
Set objMotorBike = New MotorBike
objMotorBike.Make = “KAWASAKI”
objMotorBike.Model = “Ninja ZX-10R”
objMotorBike.Combine()

If you run the page on your browser, the result is the combination of the bike manufacturer property value and the bike name property value outputted by the Combine Sub of the class. I use this feature to create the SimpleGridBuilder, a very simple database driven grid builder.
