I found an answer here, and have translated the code to VB.NET:

Public Class CustomMaskedTextBox
    Inherits MaskedTextBox

    Private m_DisableBalloonTips As Boolean
    Public Property DisableBalloonTips() As Boolean
        Get
            Return m_DisableBalloonTips
        End Get
        Set
            m_DisableBalloonTips = Value
        End Set
    End Property


    Protected Overrides Sub WndProc(ByRef m As Message)
        Private Const EM_SHOWBALLOONTIP As Integer = &H1503
        If m.Msg = EM_SHOWBALLOONTIP AndAlso DisableBalloonTips Then
            m.Result = IntPtr.Zero
            Return
        End If
        MyBase.WndProc(m)
    End Sub
End Class
