As Pete suggested:
VB.NET
Private Sub NumericTextBox_KeyPress(sender As Object, e As KeyPressEventArgs) Handles RollTemp_BOTTextBox.KeyPress, OtherTextBox.KeyPress, YetAnotherTextBox.KeyPress
    Dim keyChar = e.KeyChar
    If Char.IsControl(keyChar) Then
        'Allow all control characters.
    ElseIf Char.IsDigit(keyChar) OrElse keyChar = "."c Then
        Dim box As TextBox = DirectCast(sender, TextBox)
        Dim text As String = box.Text
        Dim selectionStart As Integer = box.SelectionStart
        Dim selectionLength As Integer = box.SelectionLength
        text = text.Substring(0, selectionStart) & keyChar & text.Substring(selectionStart + selectionLength)
        
        Dim valueInt32 As Integer
        Dim valueDouble As Double
        
        If Integer.TryParse(text, valueInt32) AndAlso valueInt32 > 999 Then
            ' Reject an integer that is longer than 3 digits.
            e.Handled = True
        ElseIf Double.TryParse(text, valueDouble) AndAlso text.IndexOf("."c) < text.Length - 4 Then
            ' Reject a real number with two many decimal places.
            e.Handled = True
        End If
    Else
        ' Reject all other characters.
        e.Handled = True
    End If
End Sub
