Hi.

I've just trying to make a class, and I have a error, that I need help with.

I have no problem getting data into my collection class, but I have problems
using the functions 'Exists' and 'Item'........... Error 427: Object
required

Can you tell me why ?

Thanks
Flemming



My Class 'clsErrCode' looks like this:
Option Explicit

Private mvCodeID As Variant
Private msName As String
Private mdFreq As Double
Private mdDura As Double


Public Property Let CodeID(ByVal vValue As Variant)
mvCodeID = vValue
End Property
Public Property Get CodeID() As Variant
CodeID = mvCodeID
End Property


Public Property Let Name(ByVal sValue As String)
msName = sValue
End Property
Public Property Get Name() As String
Text = msName
End Property


Public Property Let Frequency(ByVal dValue As Double)
mdFreq = dValue
End Property
Public Property Get Frequency() As Double
Frequency = mdFreq
End Property


Public Property Let Duration(ByVal dValue As Double)
mdDura = dValue
End Property
Public Property Get Duration() As Double
Duration = mdDura
End Property


My collection class 'clsErrCodes' looks like this:
Option Explicit

Private mCol As Collection

' Tilføjer Code til samlingen
mCol.Add vntCode, CStr(vntCode)

' Sætter Code's Egenskaber
objErrCode.CodeID = vntCode

' Returnerer 'ErrCode' objektet
Set Add = objErrCode
' End If

Set objErrCode = Nothing
Exit Function

End Sub
Private Sub Class_Terminate()

Trying to display something with this command:
gobjErrCodes is the global variable of clsErrCodes that have been
filled - the 'Count' works fine.
MsgBox gobjErrCodes.Item(2).CodeID & vbCrLf & _
gobjErrCodes.Item(2).Name

Hi

Succes for me - I made it work :-)

Fleming,

This was a complex one (must admit, your code looks overly complex for an
errors collection). I had it down to look at tomorrow.

Can you post you solution? If I do look at it I will post my suggestion.

Bob, He wasn't adding the instance of the of the object to the
collection.

Flemming, Are you aware your allows you to short cut the Item method
in the traditional manner i.e.

MsgBox gobjErrCodes(2).CodeID & vbCrLf & _
gobjErrCodes(2).Name

Hi

Thanks for looking - but don't waste you time it is solved.

In the Add function the line
Dim objErrCode As clsErrCode
should be
Dim objErrCode As New clsErrCode

I belive there was some other small things, but the New part is the main
part.
