Just a beginner....here's something I'm using to emulate the Microsoft "Print" functionality, where you can enter page numbers to print seperated by commas or specify a range using the "-" symbol. The expression checks across a whole string looking for anything that is NOT equal to a number, a minus symbol, a comma and a space character. You can use this expression to do a quick true-false check to see if the user has entered a valid string / page numbers. Later you could then write a routine to sort and / or process the input. Nothing fancy but might help someone. Comments welcome. |
