Classic ASP class constructors with parameters

John Avis by | June 8, 2016 | Classic ASP Web Development

Although probably no one cares about Classic ASP, except those who still need to support it, I was refreshing my memory today on how to use classes in Classic ASP and found a couple of options for simulating constructors with parameters.
Although probably no one cares about Classic ASP, except those who still need to support it, I was refreshing my memory today on how to use classes in Classic ASP and found a couple of options for simulating constructors with parameters.

We start with a simple class and add a default function that returns the current instance:

Class MyClass
Private m_myvalue

Public Default Function Init(myvalue)
m_myvalue= myvalue

Set Init = Me
End Function

Public Property Get MyValue
MyValue = m_myvalue
End Property
End Class

Then we can create an instance of our class with a faux constructor, like this...

Set myobject = (New MyClass)(123)

...or, if you prefer, this...

Set myobject = New MyClass.Init(123)
