EdMan apoligies for the lack of explanation on the tip/trick, thought the title gave it away, sometimes we forget to remember that the tip/tricks that we supply are also read by newbies to the language and should be adaquately explained. String.Format is a very important tool you will want to read up on this topic. A simple example would be MessageBox.Show(String.Format("Your Name is {0}!!!", textBox1.Text)); if the text in textBox1 is EdMan the output would be.... Your Name Is EdMan!!!

Am I missing something?
