Clear a MaskEditBox control without raising error

You can't clear the contents of a MaskEdBox control by setting the Text property to a null string if the MaskEdBox's Mask property contains delimiter. In fact, you must include those separators in the value you assign to the Text property, otherwise you get Error 380 - Invalid property value.

A simpler way to clear the contents of this control is to temporarily clear the Mask property, then assign a null string to the Text property, and finally restore the original Mask property, as in:

Private Sub cmdClear_Click()
    Dim tmp As String

    With MaskEdBox1
        tmp = .Mask
        .Mask = ""
        .Text = ""
        .Mask = tmp
    End With
End Sub
