MatchFound, MatchRequired Properties Example

The following example uses the MatchFound and MatchRequired properties to demonstrate additional character matching for ComboBox. The matching verification occurs in the Change event.

In this example, the user specifies whether the text portion of a ComboBox must match one of the listed items in the ComboBox. The user can specify whether matching is required by using a CheckBox and then type into the ComboBox to specify an item from its list.

To use this example, copy this sample code to the Script Editor of a form. To run the code you need to open the form so the Open event will activate. Make sure that the form contains:

• A ComboBox named ComboBox1 that is bound to the Subject field.
  
  
• A CheckBox named CheckBox1.

Sub CheckBox1_Click()
    Set ComboBox1 = Item.GetInspector.ModifiedFormPages("P.2").Controls("ComboBox1")
    Set CheckBox1 = Item.GetInspector.ModifiedFormPages("P.2").Controls("CheckBox1")

    If CheckBox1.Value = True Then
        ComboBox1.MatchRequired = True
        MsgBox "To move the focus from the ComboBox, you must match an entry in the list or press ESC."
    Else
        ComboBox1.MatchRequired = False
        MsgBox " To move the focus from the ComboBox, just tab to or click another control. Matching is optional."
    End If
End Sub

Sub Item_PropertyChange(byval pname)
    if pname = "Subject" then
        Set ComboBox1 = Item.GetInspector.ModifiedFormPages("P.2").Controls("ComboBox1")
        If ComboBox1.MatchRequired = True Then
        'MSForms handles this case automatically
        Else
            If ComboBox1.MatchFound = True Then
                MsgBox "Match Found; matching optional."
            Else
                MsgBox "Match not Found; matching optional."
            End If
        End If
    end if
End Sub

Sub Item_Open()
    Set ComboBox1 = Item.GetInspector.ModifiedFormPages("P.2").Controls("ComboBox1")
    Set CheckBox1 = Item.GetInspector.ModifiedFormPages("P.2").Controls("CheckBox1")

    For i = 1 To 9
            ComboBox1.AddItem "Choice " & i
    Next 
    ComboBox1.AddItem "Chocoholic"

    CheckBox1.Caption = "MatchRequired"
    CheckBox1.Value = True
End Sub
