Answer 1

If you need to do that, you could simply run a Replace from Edit menu using strcpy(x,"string is string") to be replaced and _tcscpy(x,_T("string is string")); as substitution, setting "Whole project".

Answer 2

First, you import API of regular expression in your class for use it:

using System.Text.RegularExpressions;

Second in your method, instantiate new Regex:

Regex regexName = new Regex(@"string of regexExpression", RegexOptions.IgnoreCase);

Third, you analize your string or for extract your prefered part of string:

MatchCollection nameOfResult = regexName.Matches(this.yourString);
foreach (Match result in nomeOfResult)
        {
            System.out.println(result.ToString());
        }

Third-one, if you replace part of string corresponding your regex:

Regex.Replace(yourString, regexName);

Try by this pattern : strcpy.*x,.*string.*is.string. For pattern or for test pattern use this: http://rubular.com/ or this: http://myregexp.com/
