There are some different ways.
Plain string methods:
Dim left As Integer = str.IndexOf('(')
Dim right As Integer= str.IndexOf(')')
Dim content As String = str.Substring(left + 1, right - left - 1)
Regular expression:
Dim content As String = Regex.Match(str, "\((.+?)\)").Groups[1].Value

For the general problem, I'd suggest using Regex. However, if you are sure about the format of the input string (only one set of parens, open paren before close paren), this would work:
int startIndex = s.IndexOf('(') + 1;
string result = s.Substring(startIndex, s.LastIndexOf(')') - startIndex);

With regular expressions.
Dim result as String = System.Text.RegularExpressions.Regex.Match("GREECE (+30)", "\((?<Result>[^\)]*)\)").Groups["Result"].Value;
Code is not tested, but I expect only compilation issues.

You could look a regular expressions, or otherwise play with the IndexOf() function

In Python, using the string index method and slicing:
>>> s = "GREECE(+30)"
>>> s[s.index('(')+1:s.index(')')]
'+30'
