I'm old fashioned procedure programmer still transitioning. I had this idea for a log file I'd create a class LogFile, then do
logFile = new LogFile();

Open in new window

and but then what do I do if there's a problem opening the log file? How do I say, "Sorry, couldn't create that class, there was a problem."?

a) First of all, you shouldn't be trying to open a file within the constructor of a class (or for that matter, do anything whatsoever other than create the object and perform some very conservative initialization).
b) There are many ways to "say" there is a problem.  You could throw an exception, use an assert, create a pop-up window, etc.

If you must do it in line 1 above, then write the code in the class's constructor.

Don't do it in the constructor.
