Couleur de fond d'un contrôle slider

Bonjour a tous

Quelqu'un peut me dire dans un 1^er temps si il y a un inconvénient à utiliser cette méthode pour mettre une couleur de fond sur un contrôle slider ?
Et si il est possible de gérer cet événement si le contrôle est placé sur une picturebox ?

dans un module :

Option Explicit

Public defWindowProc As Long
Public hSliderHwnd As Long
Private hSliderBGBrush As Long

Private Const WM_USER = &H400&
Private Const TBM_GETTOOLTIPS = (WM_USER + 30)
Private Const TTM_ACTIVATE = (WM_USER + 1)

Private Const GWL_WNDPROC As Long = (-4)
Private Const WM_GETMINMAXINFO As Long = &H24
Private Const WM_TIMECHANGE = &H1E
Private Const WM_DESTROY = &H2

Private Const WM_CTLCOLORSTATIC = &H138

                Else
                  WindowProc = CallWindowProc(defWindowProc, hWnd, uMsg, wParam, lParam)
                  Exit Function

          End Select
End Function

dans un form :

- 1 Slider: Slider1
- 1 checkbox: Check1

Option Explicit

Private Sub Form_Load()
    CreateSliderBrush RGB(255, 255, 255), False
    hSliderHwnd = Slider1.hWnd
    Call SubClass(Me.hWnd)
    Check1.Value = vbChecked
End Sub

Private Sub Form_Unload(Cancel As Integer)
   If defWindowProc <> 0 Then
      Call UnSubClass(Me.hWnd)
   End If
     Call DeleteSliderBrush
End Sub

Private Sub Check1_Click()
    Slider_ActivateToolTips Slider1.hWnd, (Check1.Value = vbChecked)
End Sub

Autre question :
Disons que j'ai un groupe de 10 slider.
Je devrais gérer de cette façon :

Option Explicit

Dim i As Long

Private Sub Form_Load()
    CreateSliderBrush RGB(255, 255, 255), False
For i = 0 To 9
    hSliderHwnd = Slider1(i).hWnd

Next
    Call SubClass(Me.hWnd)
    Check1.Value = vbChecked
End Sub

Private Sub Form_Unload(Cancel As Integer)
   If defWindowProc <> 0 Then
      Call UnSubClass(Me.hWnd)
   End If
     Call DeleteSliderBrush
End Sub

Private Sub Check1_Click()
For i = 0 To 9
    Slider_ActivateToolTips Slider1(i).hWnd, (Check1.Value = vbChecked)
Next
End Sub

Quelqu'un sait pourquoi je n'ai qu'un contrôle qui prend la couleur de fond ?

Merci

Cela est il possible ?

Ou je fait erreur dans mon code ?
