In my study of RaiseEvent, I have a Question.
I have 2 Textboxes in UserForm1: TextBox1, TextBox2
When I run, Event is fired only on TextBox2.

TextBox1 does not fire Event.
What is the problem??

my codes...

---(Class1 module)-----
Private WithEvents mTx As MSForms.TextBox
Public Event F1Pressed()

Public Property Set Control(ByRef Ctl As MSForms.TextBox)
Set mTx = Ctl
End Property

Private Sub mTx_KeyDown( _
ByVal KeyCode As MSForms.ReturnInteger, _
ByVal Shift As Integer)

If Shift Then Exit Sub
RaiseEvent F1Pressed
End Sub

--(UserForm1 module)---------
Private Col As VBA.Collection
Private WithEvents myCls As Class1


Private Sub UserForm_Initialize()
Dim Ctl As Control

Set Col = New VBA.Collection

For Each Ctl In Controls
If TypeOf Ctl Is MSForms.TextBox Then
Set myCls = New Class1
Set myCls.Control = Ctl
Col.Add myCls
End If
Next

End Sub

Private Sub myCls_F1Pressed()
MsgBox "F1 Clicked"
End Sub
