Hi guys,

I´m tying to be able to scroll up down with my mouse on a frame inside a userform, but so far I was not able to make it work,

I´ve searched and I came across this code, which I will paste below, changed the name of the userform, also the name of the frame on the userform module, but it continues not working,

#it does not give any error, simply does not work.

This is the example file FormScroll.xls

and here is the code pasted on the main Module

Option Explicit
Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" _
   (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Private Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA" _
      (ByVal hwnd As Long, ByVal nIndex As Long) As Long
Private Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" _
      (ByVal hwnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long
Private Const GWL_STYLE As Long = (-16)           'The offset of a window's style
Private Const WS_SYSMENU As Long = &H80000        'Style to add a system menu
Private Const WS_MINIMIZEBOX As Long = &H20000    'Style to add a Minimize box on the title bar
Private Const WS_MAXIMIZEBOX As Long = &H10000    'Style to add a Maximize box to the title bar
'To be able to scroll with mouse wheel within Userform
Private Declare Function CallWindowProc Lib "user32.dll" Alias "CallWindowProcA" ( _
    ByVal lpPrevWndFunc As Long, ByVal hwnd As Long, ByVal Msg As Long, ByVal wParam As Long, _
    ByVal lParam As Long) As Long

Private Const GWL_WNDPROC = -4
Private Const WM_MOUSEWHEEL = &H20A
Dim LocalHwnd As Long
Dim LocalPrevWndProc As Long
Dim myForm As UserForm
Private Function WindowProc(ByVal Lwnd As Long, ByVal Lmsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
'To handle mouse events
Dim MouseKeys As Long
Dim Rotation As Long
If Lmsg = WM_MOUSEWHEEL Then
    MouseKeys = wParam And 65535
    Rotation = wParam / 65536
    'My Form s MouseWheel function
'=================================================================
    UserForm1.MouseWheel Rotation
'=================================================================
End If
WindowProc = CallWindowProc(LocalPrevWndProc, Lwnd, Lmsg, wParam, lParam)
End Function
Public Sub WheelHook(PassedForm As UserForm)
'To get mouse events in userform
On Error Resume Next
Set myForm = PassedForm
LocalHwnd = FindWindow("ThunderDFrame", myForm.Caption)
LocalPrevWndProc = SetWindowLong(LocalHwnd, GWL_WNDPROC, AddressOf WindowProc)
End Sub
Public Sub WheelUnHook()
'To Release Mouse events handling
Dim WorkFlag As Long
On Error Resume Next
WorkFlag = SetWindowLong(LocalHwnd, GWL_WNDPROC, LocalPrevWndProc)
Set myForm = Nothing
End Sub
and here is the part pasted on the userform module

Public Sub MouseWheel(ByVal Rotation As Long)
'************************************************
' To respond from MouseWheel event
' Scroll accordingly to direction

Select Case Frame1_(mouseOverFrame_).ScrollTop - Sgn(Rotation) * 18
Case Is < 0
Frame1_(mouseOverFrame_).ScrollTop = 0
Case Is > Frame1_(mouseOverFrame_).ScrollHeight
Frame1_(mouseOverFrame_).ScrollTop = Frame1_(mouseOverFrame_).ScrollHeight
Case Else
Frame1_(mouseOverFrame_).ScrollTop = Frame1_(mouseOverFrame_).ScrollTop - Sgn(Rotation) * 18
End Select
End Sub

I´m using excel 2010 and win 7, 32 bit as shown below
