Creating a new Object
 
I am experimentins with the Collection Object and want to create a new object
to hold a user defined type.
I want to store my data in the user defined type and keep track of the sets
of data using the collection. I have never used the Class module before, can
anyone point me in the right direction?

Creating a new Object
 
Hi Tony

Crashcourse:

Create a new class module. Name it "MyClass1" (without the quotes). Paste
this code into it:

'************ MyClass1 code ***********
Option Explicit

Public LID As Long
Public SName As String

Public Sub SpeakMe()
MsgBox "My name is " & SName & " and my ID is " & LID
End Sub
'*************** end MyClass1code ************

Insert a standard module. Paste this code itno it:

'************ Module 1 code: ************

Option Explicit

Public TheCol As Collection

Sub InitMe()
Dim i As Long
Dim NewClass As MyClass1
Set TheCol = Nothing
Set TheCol = New Collection

For i = 1 To 1000
Set NewClass = New MyClass1
NewClass.LID = i
NewClass.SName = Chr((i Mod 26) + 65) & _
Chr(Int(Rnd * 26) + 97)
TheCol.Add NewClass, "C" & NewClass.LID
Next

End Sub

Sub TestMe()
Dim i As Long
Dim ThisClass As MyClass1
i = Val(InputBox("ID to speak:"))
Select Case i
Case 1 To TheCol.Count
Set ThisClass = TheCol("C" & i)
Call ThisClass.SpeakMe
Set ThisClass = Nothing
Case Else
End Select
End Sub

'************ End Module 1 code: ************

Now runf initme and then several ibstances of TestMe. I believe you will
figure our what happens.

This has endless possibilities, so don't give up if it's a little confuring
the first time.

After a while, you may replace Public LID As Long with "property let" and
"property get" code, those are event macros running when you assign and read
the variables. But that is the next level...

HTH. Best wishes Harald

Ouch. Apologies for all typos, this went just a little too fast. And put

Set NewClass = Nothing
right after
TheCol.Add NewClass, "C" & NewClass.LID

Many thanks, example was perfect. I have adapted it into a particular
spreadsheet that I am using.

Another novice question, is it posible to step through the collection in Key
order, or is it only possible to use a loop to go from 1 to collection count?

Hi Tony

Glad it was useful.

As long as you know what's in the collection, you can do things like

For Each ThisClass in TheCol
Call ThisClass.SpeakMe
Next

The key is a string. Keys aren't necessarily ordered, they just have to be
unique.

Now don't ask. Experiment.

Hi Jason

I would say that a card is a card and an ace is an ace. If some logic (like
a card game rule) gives an ace two meanings, depenging on this or that
(usually what returns the most valuable hand) then this decision (value 1 or
14) should be dealt with by the logic, the game, not by the card itself. So
leave the class as is, give the ace a single value and let your
poker/blackjack/whatever program decide how to use it.

My 0.02 only, but nobody else has replied so far :-)
Best wishes Harald

Hi Harald,
Maybe you can help?
About a year ago I gave up on a project because I got stuck!! it
involved class modules
The first class was called ClsCard and is supposed to represent a
playing card.
The code in the class module was as below.
Please let me know if you think the logic of my code is ok as the main
reason for the project was to try to get into class modules.
The problem i had was what to do with the ace, as the value can be
either 1 or 11- how can the class module handle this??
Any help greatly appreciated.
Jason
