Axapta Validation Class

I've written a method to handle regex validation in AX2009. Problem is that it always returns false, no matter what the expression or input string. Returns n开发者_如何学运维o errors, just 'false' Mind taking a look? I'm probably missing something simple.

This post has been updated to included the corrected method, without the error, so you can cut and paste the code for use in your project. BP compliant and ready for use. - Enjoy

static boolean validateMe(str regexFilter, str _testString)
{
    System.Text.RegularExpressions.Match regExMatch;
    boolean retVal;
    str regExpression;
    ;

    //See if any of the static expressions were selected
    switch (regexFilter)
    {
        case 'integer' :
            regExpression = '^\\d+$';
            break;
        case 'rgbcolor' :
            regExpression = '^([01]?\\d\\d?|2[0-4]\\d|25[0-5])\\,([01]?\\d\\d?|2[0-4]\\d|25[0-5])\\,([01]?\\d\\d?|2[0-4]\\d|25[0-5])$';
            break;
        case 'number' :
            regExpression = '^(\\d+\\.?\\d*|\\d*\\.?\\d+)$';
            break;
        case 'email' :
            regExpression = '^([\\w-\\.]+)@((\\[[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}\\.)|(([\\w-]+\\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\\]?)$';
            break;
        case 'phone' :
            regExpression = '^(\\()?(\\d{3})(\\)|-)?([0-9]{3})(-)?([0-9]{4}|[0-9]{4})$';
            break;
        case 'nopunctationphone' :
            regExpression = '^\\d{10}$';
            break;
        default :
            //No static expression matched, use the passed-in value
            regExpression = regexFilter;
    }

    //see if the string matches
    if (_testString != '')
    {
        //see if string matches expression; validation is good
        regExMatch = System.Text.RegularExpressions.Regex::Match(_testString, regExpression);
        retVal = regExMatch.get_Success();
    }
    else
    {
        //string does NOT match expression; validation fails
        retVal = false;
    }

    return retVal;
}

You have swapped the variables it should be:

regEx = new System.Text.RegularExpressions.Regex(regExpression);

Could it be that you need to escape the backslashes inside strings?

regExpression = '^\\d*$';

etc.
