Hello, when I have multiple instances of a form the RaiseEvent only works for the latest instance of the form.  Can anyone tell me what I am doing wrong?

Thanks

Probably not without seeing what your code looks like  :)

How are you calling it?

'Form1 calls Form2 when command1 clicked.

'Form1
Private WithEvents f2 As Form2
Dim i As Integer
Dim collForm2 As New Collection


Private Sub Command1_Click()
i = i + 1
Set f2 = New Form2
    f2.initialise i
    f2.Show
    collForm2.Add f2
   
   
End Sub

Private Sub f2_ItemClicked(a As Integer, b As Date)
MsgBox a & "," & b
End Sub


'Form2 RaisesEvent for Form1 when Command1 clicked
'Form2

Public Event ItemClicked(a As Integer, b As Date)
Private m_i As Integer

Public Sub initialise(i As Integer)
    m_i = i
End Sub
Private Sub Command1_Click()
    RaiseEvent ItemClicked(m_i, Now)
End Sub

your f2 will get override by the new form
you should use class

i.e.
in form1

Dim i As Integer
Dim cls1() As Class1

Private Sub Command1_Click()
i = i + 1
ReDim Preserve cls1(i)
Set cls1(i) = New Class1
cls1(i).initialise i
End Sub

in form2

Public Event ItemClicked(a As Integer, b As Date)
Private m_i As Integer

Public Sub initialise(i As Integer)
    m_i = i
End Sub
Private Sub Command1_Click()
    RaiseEvent ItemClicked(m_i, Now)
End Sub

in class1
Private m_i As Integer
Dim WithEvents f2 As Form2

Public Sub initialise(i As Integer)
    m_i = i
    Set f2 = New Form2
    f2.initialise i
    f2.Show
End Sub

Private Sub f2_ItemClicked(a As Integer, b As Date)
MsgBox a & "," & b
End Sub
