Let's face the truth: if you want to display "0" the [MinValue; MaxValue]
must include 0 as it would otherwise be rejected and you can't force any
text via the Text property or suchlike.
So I suggest MinValue = 0, MaxValue = Year(Now()) and this (hopefully not
too messy) code:
Public Sub SpinBox1_Change()
If SpinBox1.Value = 1999 Then
SpinBox1.Value = 0
Endif
If SpinBox1.Value And SpinBox1.Value < 2000 Then
SpinBox1.Value = 2000
Endif
End
But no, I don't know any cool trick...
