Program freezes

Andy Dowd

Hi, can someone help me, I don't know what to do to stop my program from freezing when there are no more results. Here is the snippet of code

  while (codeCollection.Count < numberOfCodes)


            String currentCode = generateCode();


            CodeVerification cv = new CodeVerification();


           
            if ((cv.checkWords(currentCode) == -1) && (cv.checkSameChars(currentCode) == -1) && (cv.checkCodeMix(currentCode, percentLet, percentNum) == -1))

		{
                if (codeCollection.Add(currentCode))

                {
                    filePrint.WriteLine(currentCode);
                }
            }
            }

This is part of a program to generate random numbers (codes) and when there are more codes requested than are possible (hashset doesn't take duplicates) the program freezes, I tried to put in a try catch block but it didn't work, any suggestions??

Thanks

If it is freezing in Debug builds u will be lucky enough.
If you are running multilple threads.. may be thread synchronization issues. Check the memory usage of the app. it is growing then may be coz of memeory leaks.. try to look for un-managed objects.
may be unhandled exceptions causing some issue.. to check any of the exceptions thrown in this scenario from visual studio enable break on exceptions.. may be it will give a clue.
Difficult to guess the exact reason.. may be a profilers can give u some clues.

Do you know how to use the debugger to single-step through code and to see what the actual data is?

I would recommend and download ANTS Profiler from RedGate Software. It has a 14 days free trial. It will tell you exactly what line of code (even within the assembly) took how much time and where it got stuck.
Hope it helps!
