pro_vb thread: RE: collections and classes combined


Message #1 by Godfroy Touglo <GodfroyT@n...> on Thu, 31 Aug 2000 17:32:31 -0400
Suppose in a Customer Order system you have an OrderItem class and an order
items collection class called OrderItemCol 
In order to read OrderItem out of the collection, you would do:


Private Sub Class_Initialize()
  Set mcolOrderItem = New Collection
End Sub

Sub ....' Your procedure name
Private mcolOrderItem As Collection
Dim objOrderItem As OrderItem
  Dim lngIndex As Long

  For lngIndex = mcolOrderItem.Count To 1 Step -1
    Set objOrderItem = mcolOrderItem.Item(lngIndex)
    With objOrderItem
	'Put the code to read the members
    End With

  Next lngIndex
End sub

Notes: make sure you implement the COUNT and ITEM member functions which
will wrap VB collection count and Item member functions.

		Dear:  John Smiley

		I have 3 of your books (beginning,examples and objects) I
have gone thru 
		the object book.  I really like the concept, but am lost
with using the 
		collection when i need to get an object out of the
collection.  I have 
		added and removed objects in the collection fine, only need
to retrieve the 
		information out of it.

		Can you give a snippett of code that can help.
		I have been reviewing your book for the last 2 weeks to get
this new object 
		and collection down cause I will be using it at work along
with integrating 
		crystal reports and oracle.  This all is very exciting, but
need this vital 
		piece to put everything together like a puzzle.

		thanks krunch97

		ps:  waiting for that web book you're writing.
