Just a simple regExp to parse the stack trace. Developed when using the exception block from MS, coz they only showed the stack all bunched together. Could be used as follows: [C#] string regExParams = @"(at\s)(?<fullClassName>.+)(\.)(?<methodName>[^\.]*)(\()(?<parameters>[^\)]*)(\))((\sin\s)(?<fileName>.+)(:line )(?<lineNumber>[\d]*))?"; Regex re = new System.Text.RegularExpressions.Regex(regExParams,RegexOptions.Compiled); MatchCollection mtc; mtc = re.Matches(System.Environment.StackTrace); foreach(Match mt in mtc) { MessageBox.Show(mt.Result("${fullClassName}")); MessageBox.Show(mt.Result("${methodName}")); MessageBox.Show(mt.Result("${parameters}")); MessageBox.Show(mt.Result("${fileName}")); MessageBox.Show(mt.Result("${lineNumber}")); } Seems to work well, but use at your own peril!! Feel free to use and enhance (there's probably a lot that could be done, like getting parameters individually(?), etc)

This is just a regular special char expression used to get the hax0rs off your back (hopefully). You can use this for regular open name checking if you wanted. It only fails on the insert of anything other than a-z, A-Z, and ' or whitespace. I'm open to suggestions, but try to email them to me as well as posting them to help others. Thanks.
