Adding event listener to several comboboxes

问题


I'm basically trying to display different sets of textboxes on a userform depending on the value taken by a combobox. I have created a class module called CControlEvents in which I describe the events that should occur when I change the value of the combobox : 

Private WithEvents mclsCbx As MSForms.ComboBox

Private WithEvents UnitmclsTbx As MSForms.TextBox
Private WithEvents UnitmclsTbxLabel As MSForms.Label

Private WithEvents SpecMinMoymclsTbxLabel As MSForms.Label
Private WithEvents SpecMaxMoymclsTbxLabel As MSForms.Label

Private WithEvents SpecMinIndmclsTbxLabel As MSForms.Label
Private WithEvents SpecMaxIndmclsTbxLabel As MSForms.Label

Private WithEvents SpecMinMoymclsTbx As MSForms.TextBox
Private WithEvents SpecMaxMoymclsTbx As MSForms.TextBox
Private WithEvents SpecMinIndmclsTbx As MSForms.TextBox
Private WithEvents SpecMaxIndmclsTbx As MSForms.TextBox

Private WithEvents ListmclsTbxLabel As MSForms.Label
Private WithEvents ListmclsTbx As MSForms.TextBox

Private mMyProperty As Integer

Public Property Set Cbx(ByVal clsCbx As MSForms.ComboBox): Set mclsCbx = clsCbx: End Property
Public Property Get Cbx() As MSForms.ComboBox: Set Cbx = mclsCbx: End Property

'Property pour les textbox et labels
'TextBox d'unité
Public Property Set UnitTbx(ByVal clsTbx As MSForms.TextBox): Set UnitmclsTbx = clsTbx: End Property
Public Property Get UnitTbx() As MSForms.TextBox: Set UnitTbx = UnitmclsTbx: End Property
'Label d'unité
Public Property Set UnitTbxLabel(ByVal clsTbx As MSForms.Label): Set UnitmclsTbxLabel = clsTbx: End Property
Public Property Get UnitTbxLabel() As MSForms.Label: Set UnitTbxLabel = UnitmclsTbxLabel: End Property

'TextBox de spécification minimum moyenne
Public Property Set SpecMinMoyTbx(ByVal clsTbx As MSForms.TextBox): Set SpecMinMoymclsTbx = clsTbx: End Property
Public Property Get SpecMinMoyTbx() As MSForms.TextBox: Set SpecMinMoyTbx = SpecMinMoymclsTbx: End Property
'Label de spécification minimum moyenne
Public Property Set SpecMinMoyTbxLabel(ByVal clsTbx As MSForms.Label): Set SpecMinMoymclsTbxLabel = clsTbx: End Property
Public Property Get SpecMinMoyTbxLabel() As MSForms.Label: Set SpecMinMoyTbxLabel = SpecMinMoymclsTbxLabel: End Property
'Label de spécification maximum moyenne
Public Property Set SpecMaxMoyTbxLabel(ByVal clsTbx As MSForms.Label): Set SpecMaxMoymclsTbxLabel = clsTbx: End Property
Public Property Get SpecMaxMoyTbxLabel() As MSForms.Label: Set SpecMaxMoyTbxLabel = SpecMaxMoymclsTbxLabel: End Property
'TextBox de spécification max moy
Public Property Set SpecMaxMoyTbx(ByVal clsTbx As MSForms.TextBox): Set SpecMaxMoymclsTbx = clsTbx: End Property
Public Property Get SpecMaxMoyTbx() As MSForms.TextBox: Set SpecMaxMoyTbx = SpecMaxMoymclsTbx: End Property

'TextBox de spécification minimum individuelle
Public Property Set SpecMinIndTbx(ByVal clsTbx As MSForms.TextBox): Set SpecMinIndmclsTbx = clsTbx: End Property
Public Property Get SpecMinIndTbx() As MSForms.TextBox: Set SpecMinIndTbx = SpecMinIndmclsTbx: End Property
'Label de spécification minimum individuelle
Public Property Set SpecMinIndTbxLabel(ByVal clsTbx As MSForms.Label): Set SpecMinIndmclsTbxLabel = clsTbx: End Property
Public Property Get SpecMinIndTbxLabel() As MSForms.Label: Set SpecMinIndTbxLabel = SpecMinIndmclsTbxLabel: End Property
'Label de spécification maximum individuelle
Public Property Set SpecMaxIndTbxLabel(ByVal clsTbx As MSForms.Label): Set SpecMaxIndmclsTbxLabel = clsTbx: End Property
Public Property Get SpecMaxIndTbxLabel() As MSForms.Label: Set SpecMaxIndTbxLabel = SpecMaxIndmclsTbxLabel: End Property
'TextBox de spécification max individuelle
Public Property Set SpecMaxIndTbx(ByVal clsTbx As MSForms.TextBox): Set SpecMaxIndmclsTbx = clsTbx: End Property
Public Property Get SpecMaxIndTbx() As MSForms.TextBox: Set SpecMaxIndTbx = SpecMaxIndmclsTbx: End Property

'TextBox de liste déroulante
Public Property Set ListTbx(ByVal clsTbx As MSForms.TextBox): Set ListmclsTbx = clsTbx: End Property
Public Property Get ListTbx() As MSForms.TextBox: Set ListTbx = ListmclsTbx: End Property
'Label de liste déroulante
Public Property Set ListTbxLabel(ByVal clsTbx As MSForms.Label): Set ListmclsTbxLabel = clsTbx: End Property
Public Property Get ListTbxLabel() As MSForms.Label: Set ListTbxLabel = ListmclsTbxLabel: End Property

Public Property Get MyProperty() As Integer
MyProperty = mMyProperty
End Property

Public Property Let Transition(Value As Integer)
mMyProperty = Value
End Property


Private Sub mclsCbx_Change()

If (Me.Cbx.Text = "NUM") Then

    UnitTbx.Visible = True
    UnitmclsTbxLabel.Visible = True
    SpecMinMoymclsTbxLabel.Visible = True
    SpecMinMoymclsTbx.Visible = True
    SpecMaxMoymclsTbx.Visible = True
    SpecMaxMoymclsTbxLabel.Visible = True

    SpecMinIndmclsTbxLabel.Visible = True
    SpecMinIndmclsTbx.Visible = True
    SpecMaxIndmclsTbx.Visible = True
    SpecMaxIndmclsTbxLabel.Visible = True

    ListmclsTbx.Visible = False
    ListmclsTbxLabel.Visible = False

Else
    If (Me.Cbx.Text = "LIST") Then
        UnitTbx.Visible = False
        UnitmclsTbxLabel.Visible = False
        SpecMinMoymclsTbxLabel.Visible = False
        SpecMinMoymclsTbx.Visible = False
        SpecMaxMoymclsTbx.Visible = False
        SpecMaxMoymclsTbxLabel.Visible = False

        SpecMinIndmclsTbxLabel.Visible = False
        SpecMinIndmclsTbx.Visible = False
        SpecMaxIndmclsTbx.Visible = False
        SpecMaxIndmclsTbxLabel.Visible = False

        ListmclsTbx.Visible = True
        ListmclsTbxLabel.Visible = True

    End If
End If

End Sub

In the userform's code, I dynamically add such comboboxes : 

Set gclsControlEvents = New CControlEvents
    'On attribue la comboBox à une propriété de la classe créée
    Set gclsControlEvents.Cbx = oleCbx
    'On attribue une zone de texte à une propriété de la classe créée
    Set gclsControlEvents.UnitTbx = numUnitTextBox
    'Label unité
    Set gclsControlEvents.UnitTbxLabel = UnitmclsTbxLabel
    'Label spéc moy min
    Set gclsControlEvents.SpecMinMoyTbxLabel = SpecMinMoyTbxLabel
    'Zone de texte spéc moy min
    Set gclsControlEvents.SpecMinMoyTbx = SpecMinMoymclsTbx
    'Label spéc max min
    Set gclsControlEvents.SpecMaxMoyTbxLabel = SpecMaxMoyTbxLabel
    'Zone de texte spéc moy max
    Set gclsControlEvents.SpecMaxMoyTbx = SpecMaxMoymclsTbx

So, I basically add the controls in the userform code and assign them to properties of the class, then I can simply hide/show as appropriate. The problem is that when I try to add several comboboxes based on this principle, using a for loop, it works only for the last comboboxe.

EDIT : The for loop

    For i = 1 To NewSheetModelColumnsCount
     Set Lbl = Frame1.Controls.Add("Forms.Label.1", "lbl1")
     Set txtB1 = Frame1.Add("Forms.TextBox.1")

    Next i

EDIT :
I tried to solve the problem by creating a variant array of as many instances of the class CControlEvents as I need comboboxes then using the element of this array at index i-1 at each iteration, but it didn't work, here is the code :

If (NewSheetModelColumnsCount > 0) Then

       For i = 1 To 6
           Controls("headerTextBox" + CStr(i)).Visible = True
           Controls("CheckBox" + CStr(i)).Visible = True
       Next i

       For i = 11 To 16
           Controls("label" + CStr(i)).Visible = True
       Next i

       Me.indicationLabel.Visible = False

      'Name of the frame
        With Me.Frame1
            'This will create a vertical scrollbar
            .ScrollBars = fmScrollBarsVertical

            'Change the values of 2 as Per your requirements
            .ScrollHeight = 30 * NewSheetModelColumnsCount + 50
            .ScrollWidth = 30 * 50 + 50
            '
        End With

        'Tentative
        Dim classList As Variant
        ReDim classList(0 To NewSheetModelColumnsCount - 1)

        For i = 0 To NewSheetModelColumnsCount - 1
           Set classList(i) = New CControlEvents
        Next i

    For i = 1 To NewSheetModelColumnsCount

In the User-Form declare a VBA-Collection and store the instances of your class which wraps Combo-Boxes in this collection. In your class declare a Combo-Box variable WithEvents so you can handle events of the Combo-Box. HTH.
