Who's fault is it that you create remember your own security question answers??
If you can't call them, ever hear of "email"? Create another account, since they're free!, and email Yahoo's support and ask them.
Again, there is no tool to do what you want. If you believe there is, try sending them money for it and watch what happens!

Your argument is invalid, Yahoo has a process to recover password by simply answering the security question provided.
So we're only left with you asking for help hacking accounts. GO AWAY! You'll find no help here.

I need to be steered in the right direction of some thread monitor code.
I forked my large multi-threaded chat server written in c#, running in mono on a linux box.
My software (I'm assuming) is having a sort of deadlock issue after a couple days. I have always been able to identify any problems in the past by seeing exceptions and/or obtaining the right information about what piece of code is causing what. Given the remoteness of the application and the silent deadlock, I am having a terrible time finding the source of the problem.
I have thought of a way I could write a piece of code that monitors all the the threads and the threads would report back to it after their cycles. That way the monitoring thread could keep tabs on which threads are idle, stalled or otherwise. I would just print this info to the console for review.
Please I am in need of your great guidance oh wise and smarter than me developers. I need some advice on where I should head, because I'm sure one of you has had a similar situation. This has plagued me for two months. My other version which runs for a different client on a windows box and has minor changes to the codebase, can run for months.
TIA

in situations like that, and many others, what I do is add logging code; these are basically calls to a lightweight log method emitting a single line of text with a lot of information, typically time of day, threadID, and a string that is passed to the log method, describing where in the code the log is happening.
I often log to a ListBox (in a WinForms app), to the Console (when running under Visual Studio), or to a file; and often a combination of those (ListBox/Console are fine while the app runs, file is OK to keep a record).
BTW: for file logging I typically use File.AppendText which means the file is always closed, and is intact, up to the last log message, even when the app crashes.
Having log files you can watch what was happening at or around the problem point, and compare the sequence of events with others.
Once you have a single log describing a failure, you can:
- run again till the next failure, and compare failures;
- add log statements in and around suspected areas in the code;
- add assertion statements (checking invariants, things that should be true, and only logging when they aren't);
- try and find ways to up the failure frequency, which also means the waiting period between failures goes down, so you capture more information in less time.
The overall philosophy is: improve observability.
So with a threading/deadlock problem, I would add log statements to every thread-related call (thread creation, thread joins, start and end of important methods, etc). I would generate as much as 1000 logs per second, if that is required.
This special way of debugging beats the regular breakpoint/single-step approach in that it is much more automated and a lot faster; it is essential to solve problems that take a long time to occur, and/or seem to be rather random.
BTW: it could be that you are facing another problem, here are a few candidates:
- not enough error handling: something is throwing without you noticing; make sure you have all the try-catches you need; put a try-catch in the staic Main() as a safety net; install an Application.ThreadException handler. Don't ever have an empty catch block, at least log the exception.
- running out of memory; logging Environment.WorkingSet periodically (with a Windows.Forms.Timer) could be very helpful (although it might miss a "large-object-heap" fragmentation problem.
- a thread synchronization problem: lacking a lock somewhere makes your app use an invalid combination of state variable values (these may be the hardest to figure out as they very much depend on timing).

Nice response Luc
I guess a lot of people (wether they are writing Multithreaded or not) don't include any/enough observability in their code, then when the crunch comes, whammo !
I tend to use a logging/library that when Im not actually monitoring/looking for something, is cheap, ie, consumes the barest minumim resources, and doesnt log the messages until I turn a level 'on' - that way its already in my code so I dont have to go back and add it later
cheers

Thanks.
I did a lot of embedded development, mostly with soft real-time requirements; logging was the first and best tool for debugging all kinds of problems then, and it still beats an interactive debug session except for the simplest errors (the ones an experienced programmer typically doesn't make  ).
For complex apps, I have my own log class with categories one can interactively raise and lower thresholds for; I include log statements from the very beginning, and whatever debugging code I add, I never remove it again (it is part of the code, part of the effort, why throw it out?)

Excellent response, Luc! 
It reminds me a bit of my former career designing automated test systems for missiles. The #1 rule of Testability: A Testable product is both Observable and Controllable. All electronic control systems use feedback; an open-loop system is inherently undesirable, as functional accuracy is limited to component accuracy without active feedback. But if a tester cannot see interior points in the circuit, and can't open the feedback loop to measure values inside, it is not possible to test the circuit. There also must be a means to force a change of state in the circuit and observe the results in order to make an effective test.
The same principle applies to software; if you can't observe the internal states, you can't expect to diagnose a problem when it occurs. Logging - not only errors, but the system states before and after a fault - makes diagnosing the cause of a problem far easier. In many cases, it probably is the only way to diagnose a failure.

Thank you so much Luc for your awesome response! I will definitely create a logging class as it sounds like the best option.

hi, I am working on a cyber cafe program and using sql server express. Will I need to install sql server to the target pc's to use my program? And is there anything that I should be careful when compiling?
|
|
|
|
|
Maybe.
More detail would be helpful. Is it client/server? Only the server needs the server software.
|
|
|
|
|
the program is a client/server application and only server will be using the database locally
One more question: if I compile my program, is the database I created included in the compilation? (I use VS C# Express with Sql exspress)
|

The data files? No. But you could include them in the deployment/installer project.
|
|
|
|
|
|
If you run your program locally as a server, you need to install.
I think what you should be careful about is the connecting string of your database file.

Hello
I've just find out a strange behaviour of the ComboBox
If you set the DropDownWidth property of a combo the Width it not activated if the dropdown list is opened by typing text in the combo (SuggestAppend mode)
However if you open the list using the Combo button the given width is taken
And after the width is activated either using the button either by resizing the dropdowlist manualy the width setting remain active until the form is closed
How can I directly set the right width (is there an opening event that I can use)
Thanks for anu suggestion

Hello everyone.
As far as I know Jagged array is also called "array of array" does that mean that I can use a definition like int[][][] Jagged Array = new int[3][3][]? And does it mean "array of array of array"?
I mean if I use something like that does it contain 9 arrays in it? if I'm wrong how can I define something like that?
Thanks in advance!
|

Almost, yes it would be "an array of (array of (array of ints))" (with parentheses for extra clearness)
However, you can only create 1 array at the time, so you can make a new int[3][][], but then you'd have to loop over it and fill every entry with a new int[3][]
You would then have 9 places in which you could put an "array of int" (but they are all null) so only 1 + 3 arrays in total (the outer array and the three middle arrays). (until you also create the arrays of ints)
It's not all that useful to do this though (when all sub-arrays have the same length), you might as well make a new int[9][] and index it with [3*i+j] instead of [i][j], which takes much less code (you don't have to fill the outer array with arrays). You could extend this to three dimensions if all arrays of int will be the same length.
