So I thought I would move straight onto an update to this Regular Expression Evaluator tool.  What I have done code wise is only 2 lines, but for functionality and ease of use, I have added three tabs, three text boxes and another button.

• You can download the source code from here: http://andrewrea.co.uk/RegEvalTool/Part2/regevaltool.rar
• The first part which is a step by step of making the program is: http://weblogs.asp.net/andrewrea/archive/2008/04/24/creating-a-regular-expression-evaluator-program.aspx

I have extended the program so it now offers the capability of performing a Regex.Replace.  You can then test out your patterns really quickly and easily before you try to integrate into your code.  being regular expressions, you can test for all languages and they are universal (nearly).

So I have added three tabs, each with a text box inside.  The names of these I have called:

• txtPattern
• txtAfterReplacement
• txtExampleText

The code I have used for the second button function is as follows:

        private void btnReplace_Click(object sender, EventArgs e)
        {
            Regex newExpression = new Regex(txtPattern.Text);
            txtAfterReplacement.Text = newExpression.Replace(txtExampleText.Text, txtReplacementText.Text);
        }
