I did THIS and I think it is working. (I get a pop up box).
Code:
Private Sub FindFileInput_Click()
Dim f As Object
Dim strSelectedpath As String
Dim strSelectedFile As String
Dim varItem As Variant
Set f = Application.FileDialog(3)
f.AllowMultiSelect = False
If f.Show = -1 Then
For Each varItem In f.SelectedItems
strSelectedpath = varItem & "#" & varItem
strSelectedFile = Split(strSelectedpath, "\")(UBound(Split(strSelectedpath, "\")))
Next varItem
Me![txtSelectedFile] = strSelectedpath
Me![txtFileName] = strSelectedFile
Dim Msg, Style, Title, Help, Ctxt, Response, MyString
Msg = "File association successful"
Style = vbOKOnly + vbInformation + vbDefaultButton1
Title = "Association"
Help = "DEMO.HLP"
Ctxt = 1000
Response = MsgBox(Msg, Style, Title, Help, Ctxt)
If Response = vbYes Then ' User chose Yes.
MyString = "Done" ' Perform some action.
End If
End If
Set f = Nothing
End Sub
