No,no mutex is used.. Ill detail more: my project(parser XML) i allow user to enter filename of file to be parsed and directories for log files(regularTXT and html) and then allow start parsing(only if user entered file and directory). For translating txt log file to html i have checkbox and if its marked then html-convert function also starts working.. If ots not enough please tell me,also ill post the code tomoroow(although its quite long for posting) Thank you Alex

what doesn't work anymore ? have you checked the usuals ( memory leak, resource leak, ... ) ? what are the symptoms ?

I did check the usuals.. Here some details: My project(parser XML) i allow user to enter filename of file to be parsed and directories for log files(regularTXT and html) and then allow start parsing(only if user entered file and directory). For translating txt log file to html i have checkbox and if its marked then html-convert function also starts working.. So the problem is after working once,if i want to enter filename e.t.c. once more,it allows entering but it doesnt work..(if i exit from gui interface and start the programm over again it does work(but again just once),but i need it to work without exiting.. If its not enough please tell me,also ill post the code tomoroow(although its quite long for posting) Thank you Alex

You've not provided near enough information. Any attempt at a solution at this point would be futile at best. What does the program do? What are the symptoms? Has it ever worked two or more times? When the program is supposed to "run" a second time, have you stepped through the code from that point to see what is failing? Have you trimmed away all unnecessary code so that what's left is just enough to reproduce the problem?

Is ur project dialog based? Are u using any event handling? This may help to think over the problem Dipeka.A.J

did you close the files ? re-initialize variable ? reset the state of the parser ? as david wrote, did you trace the problem by putting breakpoints to see ( or try to see ) when in the execution path your program stop working properly ? don't post ALL the code, only the portions that doesn't work ( and after you really "cornered" the bug and/or the offensive function )

Hello, Ill detail more: My project(parser XML) i allow user to enter filename of file to be parsed and directories for log files(regularTXT and html) and then allow start parsing by pressing Start button which triggers start of work(only if user entered file and directory). For translating txt log file to html i have checkbox and if its marked then html-convert function also starts working.. If its not enough please tell me,also ill post the code tomoroow(although its long for posting)..And no it never worked more than once.. Symptoms are that for second try of running it does get the input but doesnt perform necessary actions as in first time.. I debugged my functions and its fine,couldnt debug GUI(mfcDlg.cpp)yet.. Thank you, Alex

For starters, set a breakpoint in the handler for the Start button. Begin debugging at that point. You might also consider judiciously-placed
ASSERT()statements. They alert you when the state of your program is not what you think/expect it to be.

I think the problem is that when i start programm for second time it has some problems with reading from the source (XML)file(.xml).. Im opening the file with GUI by using CFileDialog and also f.open in function and closing just with f.close ..Could that be the problem? If yes how do i close it with GUI? And also,Do i need to call OnInitDialog function after the programm ends for the first time? Thank you very much, Alex

How you open a file and whether the program has a GUI are mutually exclusive things. rfixxxer wrote: ...f.open in function and closing just with f.close ..Could that be the problem? I don't see how, as long as the file opened and closed with no errors. rfixxxer wrote: If yes how do i close it with GUI? Again, the opening and closing of a file is independent of whether it has a GUI or not. The key here is consistency. If you opened the file as a stream, it must be closed as a stream. If you opened the file as a handle, it must be closed as a handle. No mixing! rfixxxer wrote: Do i need to call OnInitDialog... Only as a child class calling its base class implementation. Otherwise, this function is called by the framework in response to a
WM_INITDIALOGmessage.
