 | Is this an ASMX web service or a WCF web service? Is it active or do you just have the code/assembly?  |
 | > how it is used and why we use it In theory you would use it just like char, and the purpose is to support extended character sets. The char type for character usage was really designed and intended for character sets (and language alphabets) that can fit into a … |
| | Re: delete csv file The error is precisely what it says: the file cannot be deleted until all processes have closed it and disposed of any references to it. I'd suggest downloading and running [Process Monitor](http://technet.microsoft.com/en-us/sysinternals/bb896645.aspx) to find out which process still has a lock on that file. This will give you some direction … |
| | > Daniweb rules clearly state that a thread cannot be requested to be deleted You can request for a thread to be deleted by either flagging the first post or PMing a mod directly, but that request most likely won't be granted.  |
| | > Yes, but i still need to translate it to C++. Since it's already valid C++ (assuming compiler support for non-portable stuff), you'll need to define what *you* mean by "C++".  |
| | > So, I need to implement the following class Okay. And? > Thanks you guys. For what? You completely failed to ask a question. I'll take the high ground and assume that you're not expecting us to do your homework for you. |
| | You need to actually read every line, but you can ignore the lines at a specific "index" by simply not printing them. |
 | Re: string constant > can you please explain that how "hello" is working here ? Luck. :) Technically it's undefined behavior because you're passing an object of the wrong type to printf(). Functionally though, `"hello"`, `&"hello"`, and `&("hello"[0])` all evaluate to the same address, so it's not difficult to see why your output … |
 | > I am guessing however that the pointer in the while loop is always pointing to string data, until it > iterates on the final drive, and hits another \0 character, which causes the while test to be false. Good guess. However, there's a bit of a trick here because … |
 | You can use a va_list twice, provided it's properly disposed of with va_end() and re-initialized with va_start() or copied with va_copy(). What you *can't* do is assume that va_list represents a bidirectional read-only collection. It could easily be a generated array or list of arguments that are modified or destroyed … |
| | Make sure there's a blank line before and after the code, and double tab it. |
| | Here are my downloads and impressions in order of preference so far. The season just started though. * **Genshiken Nidaime**: By far my most anticipated of the new series. I regularly reread the Genshiken manga and fully intend to follow this one to the end. * **Watashi ga Motenai no … |
| | Re: time complexity n grows by a factor of 4 (`16384 / 4096 = 4`), right? And the run time also grows by a factor of 4 (`2048 / 512 = 4`), right?. While it's certainly not a conclusive test, from those two data points you really can't do much more than say …  |
| | Re: dynamic arrays > P.S. Feel free to use new/delete if you never resize the array, they are faster operations for single allocations. I'd strongly recommend against using malloc(), calloc(), realloc() (and by extension free()) because they don't respect the presence of constructors and destructors. If you're working with any class type, you're …  |
 | Re: Sapping Storage Whew, a lot of questions. ;) I'll answer them, but before doing that I'll strongly recommend that you consider memory mapping your files if you go the route of file lists. That way you only need to manage the organization of the files themselves as well as the memory maps, … |
| | > i tried to free()mem i allocate in prog using malloc But you don't. You try to free the result of fun(), which is a pointer to int that corresponds to the address of x in main(). In other words, you're trying to free something that should not be freed. … |
| | Re: rand() > but still can you tell me the way in which it is mostly implemented ? rand() is usually implemented with some form of [linear congruential generator](http://eternallyconfuzzled.com/tuts/algorithms/jsw_tut_rand.aspx). |
| | > what do you think makes a better programmer ? It depends on the ultimate goal. If the goal is to be a programmer who can win competitions, the answer is clearly a. If the goal is to be a viable programmer in the working world, b is the answer. …  |
 | > And finally, I also share Ancient Dragon's concerns about security. Likewise. If you look at history, you'll see a distinct pattern of alternating between centralizing and decentralizing when it comes to data storage and retrieval. Right now with the whole Cloud nonsense we're in a decentralization period, but I'd …  |
 | > I see on some other forums, they have a button to mark all as read if you need, and then only the individual threads are marked if you don't use it. That's available on Daniweb as well, but from the forum list [here](http://www.daniweb.com/). > But I'm quite sure that … |
| | Re: how much time It's impossible to say since study time to a working knowledge of programming varies greatly from person to person and "working knowledge" is such a nebulous term. Can you be more specific?  |
 | Re: ide of c# > C# is a Microsoft specific language and relies on the Microsoft compiler, so your options are very limited. .NET is a Microsoft specific implementation of the CLI that includes C#. C# is an internationally standardized language whose evolution is driven solely by Microsoft presently, but there's nothing stopping someone … |

| | There are good tutorials out there if you search for them. I started writing a cryptography library a couple of years ago and abandoned it, so all of my supplementary bookmarks and references are gone, unfortunately. However, I can at least offer you a basic implementation. :) I wrote it … |
 | Just use a vector internally and copy the array into it as an alternative constructor. Or you could have the underlying collection type be a template argument to the class. Or you could use inheritance from an interface to define both an array-based class and a vector-based class. But I'd … |
| | Given that "how to develop software" is extremely broad, I'll answer the specific question you asked. > how can i make the program to remember the value the user assigned to its variables without erasing it everytime i close the exe file running the program?? Persistant data would be saved … |

 | > Are ProjectConstants::CONSTANT1 and ProjectConstants::CONSTANT2 declared in the global namespace or not? A using declaration introduces names to the current namespace, so in this case yes, they are indeed in the global namespace for that particular translation unit. |

 | localhost or not, the machine must have a mail server installed and running or SMTP simply won't work. |
 | A character literal uses single quotes, string literals use double quotes. There's a difference, and it's rather significant. ;) |

 | Re: code trick Don't run the .exe file? Anyway, that's not a "trick", it's legitimate code. There are innumerable ways a programmer can "trick" you with their code, and the solution is to avoid running programs from such programmers rather than expecting to somehow introspectively recognize the tricks in object code and "dodge" …  |

| | If you're talking about the PM notification where your private messages link turns yellow, there's not presently a way to turn it off. Further, there's an item on my bug list about that notification not being entirely accurate in all cases, but it's low priority since it doesn't happen often … |
 | Re: Windows.h > Can it be possible to give the header file windows.h in turbo c ? Note that simply getting that header would do a whole lot of nothing. A header typically contains delcarations and requires linking with a static or dynamic object library for those declarations to be useful in …  |

| | I was asked this in an interview today: Q: `malloc(0); /* What does it do? */` It's a great question because it covers a subtlety in the standard and a condition that not many people will consider. Unfortunately, I wasn't 100% confident that I remembered what the standard said about … |
