Use regular expressions (System.Text.RegularExpressions):

Dim m As Match = Regex.Match(value, "\((?<n>\d+\.\d{2})\)")
If m.Success Then
  Dim n As Decimal = Decimal.Parse(m.Groups("n").Value)
End If

If your format is going to be exactly the same, you can try using Split like you mentioned. This can be very fragile if anything changes.

See if this works for you.

Dim result As Double
Dim value As String = "hy the number is (30.01)"
Dim subValue() As String = value.Split("(")
subValue(1) = subValue(1).TrimEnd(")")
If Not Double.TryParse(subValue(1), result) Then
    'Error handling code here
End If
