On a worksheet I have 3 ActiveX objects being TextBox1, TextBox2, ListBox1
Leaving other code out I have a class clsEvents that contains
Private WithEvents txbControl As MSForms.TextBox
Private WithEvents lisControl As MSForms.ListBox
Private txbEvents As TextBoxEvents
Private lisEvents As ListBoxEvents
Private Sub txbControl_Change()
txbEvents.ChangeEvent txbControl
End Sub
Private Sub lisControl_Change()
lisEvents.ChangeEvent lisControl
End Sub
and the classes TextBoxEvents and ListBoxEvents contain
Public Event Changed(txtBox As MSForms.TextBox)
Public Sub ChangeEvent(txtBox As MSForms.TextBox)
RaiseEvent Changed(txtBox)
End Sub
Public Event Changed(ByRef myListBox As MSForms.ListBox)
Public Sub ChangeEvent(lisBox As MSForms.ListBox)
RaiseEvent Changed(lisBox)
End Sub
The worksheet module contains
Public WithEvents tbxEvents As TextBoxEvents
Public WithEvents lisEvents As ListBoxEvents
Private Sub tbxEvents_Changed(tbxBox As MSForms.TextBox)
Debug.Print "tbxEvents_Changed " & tbxBox.Name
End Sub
Private Sub lisEvents_Changed(lisBox As MSForms.ListBox)
Debug.Print "lisEvents_Changed " & lisBox.Name
End Sub
Private Sub TextBox2_Change()
Debug.Print "TextBox2_Change"
End Sub
Private Sub TextBox1_Change()
Debug.Print "TextBox1_Change"
End Sub
Private Sub ListBox1_Change()
Debug.Print "ListBox1_Changed "
End Sub
If I change something in TextBox1 or TextBox2 or ListBox1 the debugwindow shows that the events first will be send to the worksheet (TextBox1_Change etc.) followed by tbxEvents_Changed or LisEvents_Changed, so it it working.
What I would like to achieve is replacing the code in clsEvents by something like
Private WithEvents objControl As OLEobject
Private txbEvents As TextBoxEvents
Private lisEvents As ListBoxEvents
Private Sub objControl_Change()
if (TypeOf objControl.Object Is MSForms.TextBox) Then
txbEvents.ChangeEvent objControl
elseif (TypeOf objControl.Object Is MSForms.ListBox) Then
lisEvents.ChangeEvent objControl
endif
End Sub
So basically I would like to know how I can achieve a valid definition for WithEvents that will remove the necessity for 'many' eventfunctions in clsEvents.
Public WithEvents objControl As ?????
Open Notepad and copy code below and paste it in a new txt-file save it als CatchEvents2.cls
VERSION 1.0 CLASS
BEGIN
MultiUse = -1 'True
END
Attribute VB_Name = "CatchEvents2"
Attribute VB_GlobalNameSpace = False
Attribute VB_Creatable = False
Attribute VB_PredeclaredId = False
Attribute VB_Exposed = False
Private Type GUID
Data1 As Long
Data2 As Integer
Data3 As Integer
Data4(0 To 7) As Byte
End Type
#If VBA7 And Win64 Then
Private Declare PtrSafe Function ConnectToConnectionPoint Lib "shlwapi" Alias "#168" (ByVal punk As stdole.IUnknown, _
ByRef riidEvent As GUID, ByVal fConnect As Long, ByVal punkTarget As stdole.IUnknown, ByRef pdwCookie As Long, _
Optional ByVal ppcpOut As LongPtr) As Long
#Else
Private Declare Function ConnectToConnectionPoint Lib "shlwapi" Alias "#168" (ByVal punk As stdole.IUnknown, ByRef riidEvent As GUID, _
ByVal fConnect As Long, ByVal punkTarget As stdole.IUnknown, ByRef pdwCookie As Long, Optional ByVal ppcpOut As Long) As Long
#End If
Private EventGuide As GUID
Private Ck As Long
Private ctl As Object
Private CustomProp As String
Public Sub MyChange()
Attribute MyChange.VB_UserMemId = 2
Debug.Print " Change ControlName " & " Type: " & TypeName(ctl) & " CustomProp: " & CustomProp
End Sub
Public Sub ConnectAllEvents(ByVal connect As Boolean)
With EventGuide
.Data1 = &H20400
.Data4(0) = &HC0
.Data4(7) = &H46
End With
ConnectToConnectionPoint Me, EventGuide, connect, ctl, Ck, 0&
End Sub
Public Property Let Prop(newProp As String)
CustomProp = newProp
End Property
Public Property Let Item(Ctrl As Object)
Set ctl = Ctrl
Call ConnectAllEvents(True)
End Property
Public Sub Clear()
If (Ck <> 0) Then Call ConnectAllEvents(False)
Set ctl = Nothing
End Sub
In your VBA editor you import this File (right click on your VBAproject and choose import)
In a normal module you put in the code below:
Private AllControls() As New CatchEvents2
Sub connect()
Dim j As Long
With Worksheets("Sheet1")
ReDim AllControls(.OLEObjects.Count - 1)
For j = 0 To .OLEObjects.Count - 1
AllControls(j).Item = .OLEObjects(j + 1).Object
AllControls(j).Prop = .OLEObjects(j + 1).Name
Next
End With
End Sub
Sub disconnect()
Dim j As Long
For j = LBound(AllControls) To UBound(AllControls)
AllControls(j).Clear
Next j
Erase AllControls
End Sub
Now when you run the connect sub every change of any activeX control is catched
Edit: after comment to put in all other events; Other events: (all these will work on userforms also)
Public Sub MyChange()
Attribute MyChange.VB_UserMemId = 2
Debug.Print "ch"
End Sub
Public Sub MyListClick()
Attribute MyListClick.VB_UserMemId = -610
Debug.Print "cl1"
End Sub
Public Sub MyClick()
Attribute MyClick.VB_UserMemId = -600
Debug.Print "cl2"
End Sub
Public Sub MyDropButtonClick()
Attribute MyDropButtonClick.VB_UserMemId = 2002
End Sub
Public Sub MyDblClick(ByVal Cancel As MSForms.ReturnBoolean)
Attribute MyDblClick.VB_UserMemId = -601
Debug.Print "dcl"
End Sub
Public Sub MyKeyDown(ByVal KeyCode As MSForms.ReturnInteger, ByVal Shift As Integer)
Attribute MyKeyDown.VB_UserMemId = -602
Debug.Print "kd"
End Sub
Public Sub MyKeyUp(ByVal KeyCode As MSForms.ReturnInteger, ByVal Shift As Integer)
Attribute MyKeyUp.VB_UserMemId = -604
Debug.Print "ku"
End Sub
Public Sub MyMouseDown(ByVal Button As Integer, ByVal Shift As Integer, ByVal X As Single, ByVal Y As Single)
Attribute MyMouseDown.VB_UserMemId = -605
Debug.Print "md"
End Sub
Public Sub MyMouseMove(ByVal Button As Integer, ByVal Shift As Integer, ByVal X As Single, ByVal Y As Single)
Attribute MyMouseMove.VB_UserMemId = -606
Debug.Print "mm"
End Sub
Public Sub MyMouseUp(ByVal Button As Integer, ByVal Shift As Integer, ByVal X As Single, ByVal Y As Single)
Attribute MyMouseUp.VB_UserMemId = -607
Debug.Print "mu"
End Sub
Public Sub myKeyPress(ByVal KeyAscii As MSForms.ReturnInteger)
Attribute myKeyPress.VB_UserMemId = -603
Debug.Print "kp"
End Sub
Then there are 4 (userform) events: Exit, Enter, AfterUpdate and BeforeUpdate which are events of the container-control which you can't 'catch' with withevents but in this way you can:
Public Sub myExit(ByVal Cancel As MSForms.ReturnBoolean)
Attribute myExit.VB_UserMemId = -2147384829
Debug.Print "exit"
End Sub
Public Sub MyAfterUpdate()
Attribute MyAfterUpdate.VB_UserMemId = -2147384832
Debug.Print "au"
End Sub
Public Sub MyBeforeUpdate(ByVal Cancel As MSForms.ReturnBoolean)
Attribute MyBeforeUpdate.VB_UserMemId = -2147384831
Debug.Print "bu"
End Sub
Public Sub MyEnter()
Attribute MyEnter.VB_UserMemId = -2147384830
Debug.Print "enter"
End Sub
On a worksheet you've got LostFocus and GotFocus (1541 and 1542) but these I can't get to work, so if anybody knows howto it would be great. final remark: It doesnot work on a mac
