Not sure what you mean by a null string so just in case, here's two options: Null: if (myString == null) Empty: if (myString == "") -- There are 10 kinds of people. Those who understand binary and those who don't. http://code.acadx.com (Pull the pin to reply)

C Cowboy \(Gregory A. Beamer\) Dec 1, 2003 #3 Null string, as in char(0) or a string that is null: if(stringName == null) { // you detected a null string } char[] charArray = stringName.ToCharArray(); //Assume only one char if it is a null char if(charArray[0] == 0) { // only a null char } I am flying by the seat of my pants here, so you may have to alter the code to get past debug. The theory is sound, however. -- Gregory A.
