      Ok, I'll take you up on it. I've *very* new at this and assume the question is trivial, but can't seem to figure out how to get the documentation to tell me what I want to know. I need to read a string and, if it's a number, convert it to double. How do I tell whether the string (input via the Console::ReadLine() method) contains only numeric characters (and can therefor be correctly converted to double via the Convert::ToDouble() method) or not? If this turns out not to be trivial, just let me know and I'll think of something else. Maybe get a stream of chars or something (yuck!)

        Your question sounds like a sincere request for advice - and I would gladly answer it if I could - but I am only familiar with MFC and C++ - I think your question is either .NET, JAVA or C# (I have no idea).

            Even though this isn't C/C++ like Terry said, you can still use this same method that I'd use. Write a function that checks each character to see if it is a number or not. Return true if its a number and false if not. If it reaches the end of the string without returning false, then it converts it double, else it fails. Two ways I can think of to do this. One is just check the char is equal to any number 0-9 (this probably isn't the most effective way) or convert to ascii and check if it is within the ascii range for a number. Mike

              Code-Project would accept sponsors whose product was selling homework completion for students?!?!?!?!? :) :) I guess so, or you wouldn't have referred my joke to your ad dept - or was that in itself a joke??!??! I am so confused! Anyways, I was just joking. Have a cheerful day!

                I was just kidding. Maybe someone would be willing to put something together to make some $$$.

                    You could look at the System::Text::RegularExpressions namespace and create a regular expression that would match the characters 0-9...then check to see if the thing is a match. You could also use the Microsoft::VisualBasic namespace X| and the IsNumeric() function. Also, I think the Convert::ToDouble() throws an exception if the input string is not in a proper format. (Actually I know so, I just did this the other day in C#). You could wrap the call to ToDouble() in a try catch block and handle the error whichever way you want. Hope that helps... :)
