it helps some times Answer:
The problem is you are putting the exclamation mark in the wrong place. Try this:
code :
if (!file.name.match(valid)){

This might help you My current mock up has that when the match count is zero, that would signify an error and to display the message.
In this case you have to have multiple regex's and each one must be used on and pass each input box.
code :
Array of regex's:  
[0] = /something[class] something else/
[1] = /more stiff that must be in each one/

result = 1;
loop through array
    if ((result = result && match_globally(regex[i])) == 0)
        break;
end loop

if (result == 0)
    notify of an input error at regex[i] validation

Does that help You are missing double quotes, you put parameters in wrong places, and you do not need an if statement:
code :
public bool IsKosher(string input) {
    return Regex.IsMatch(input, "[A-Z]{2}_[A-Z]{2}");
}

should help you out I honestly don't know what I am doing wrong. I have checked the regex expression in http://regexpal.com/ and it works just fine , You forgot to escape your backslashes in the string literal:
code :
std::regex regex_number("((\\b[0-9]+)?\\.)?[0-9]+\\b");

may help you . Validating a regex is an incredibly complex task. A regex would not be able to do it.
A simple approach would be to catch any errors that occur when you try to run the SQL statement, then report an appropriate error back to the user.
