object orented programing?

Keddie,

you are right about constructors and destructors but you can get round it to an extent.

Say you have a class CJones

You can write an initialisation procedure, Init, say, to initialise the values in the class. (These would be user set values that cannot be set in the Class_Initialize event)

Friend Sub Init(Optional Age As Variant, Optional Height As Variant)
  If Not IsMissing(Age) Then Me.Age = Age
  If Not IsMissing(Height) Then Me.Height = Height
End Sub

Then you write a Public Function in a BAS module to instantiate the class.

Public Function New_CJones(Optional Age As Variant, Optional Height As Variant)
  Set New_CJones = New CJones
  New_CJones.Init Age, Height
End Function

Then you ask users to write:

Dim j As CJones
Set j = New_CJones(10, "1.92 Metres")

You cannot force the user to use the changed code but you can utilise this internally.

I know all that does not answer the question, but I thought you might be interested.

Cheers,

P.

Well thats thats almost the way i use, but i like to put them in the higher level object like directX control has it's Directdrawcreate and methods like blablablacreate or createblabla

Set DDraw = DirectX.DirectDrawCreate("")

OK.

Well Guess What. the contstructers for the class are the class its self, on the two drop down boxes in the vb ide, where u select an object and an event ? well goto the .cls file and seelect the class as ur object and initiate or terminate (constructor and deconstructor)

[kedaman]

Not really the same thing, you can't pass any parameters to them

[parksie]

You can't pass parameters to the destructor anyway. For the constructor, just use an Init function. BTW - if VB7 has overloaded functions then they'll be on their way to proper OOP

[KENNNY]

VB7 will have overloading functions, as well as other OOP stuff like inheritance..finally VB will be a proper OOP language (hopefully)
