| | If you are calling that from some other function then expect to use the open file handle after that function returns, then the FILE pointer must be passed by reference. What you have coded is passing by value. [code] void OpenReportFile(FILE **reportFile) { *reportFile = fopen("c:\\temp\\report.txt","wt"); if (*reportFile == NULL) … |

| | If you just want to add a new line of text at the end of the file, then open the file for append mode. Read about the [URL="http://www.cplusplus.com/reference/iostream/fstream/"]open method here[/URL]. Or call seekp() to set the file pointer to end of file before writing. If you want to add a … |

| | Find out the version of windows that is running then call LoadLibrary() if its the version you want. But what about all those calls to DLL functions? Are you going to put if statements around all of those too ? |

| | >>I would like to work on POSIX thread programming using TC v3.0 You can't -- that compiler is too ancient. STL is supplied with a compiler because it is compiler-implementation specific. Your compiler doesn't have it because the compiler pre-dates STL. Upgrade to a modern compiler such as Code::Blocks or … |
| | why? If you are new to c++ you need to learn the language first. |
| | when you type [icode]g++ main.cpp[/icode] the compiler is going to compile main.cpp then attempt to link the executable. But it can't because it doesn't know anything about CBigInteger.cpp You can solve the problem by typing this: [icode]g++ main.cpp CBigInteger.cpp[/icode] |
| | Re: Gonzobonkers Welcome to DaniWeb. Databases? Yes DaniWeb has several forums devoted to it -- they are listed under Web Development. Also questions about databases occasionally in the Software Development forums. |

| | UNICODE characters is wchar_t, which on MS-Windows is unsigned short and on some other operating systems can be unsigned long. So why not just do something like this? [code] size_t i; wchar_t buf[20]; vector<unsigned long> characters; for(i = 0; i < characters.size(); i++) buf[i] = characters[i]; buf[i] = 0; [/code] |

| | c++ is not the best language for web sites -- use java instead. But if this is not for a web site then for gui I'd use wxWidgets or OpenGL. You could use pure win32 api but it would be more difficult. |
| | The printf() statement contains %s and %f, but there are no arguments for them [code] char message[] = "Hello World"; printf("%s\n", message); [/code] In the above, mssage is passed as an argument to printf(). Your printf() needs similar arguments.  |

| | very similar, but you could fill in a struct tm with the date then call mktime() to fill in the rest, including the day-of-week. Make sure you memset the struct tm with all 0's before you start or mktime() will return an error condition. |
| | Re: need help in WTL Not certain but WTL might be dead, and it was never officially supported by Microsoft. You are better off using wxWidgets, which is portable to several operating systems, compilers, and used by lots of programmers. There are also several tutorials that you can find with google. |

 | That is sick -- no wonder our kids are so screwed up today, and it seems to get worse every year. Hope someone puts a XXX rating on that game so that only adults can buy it. Or better yet, just ban it. |
 | [quote]“security measures are inherently unreliable, can be trivially circumvented and will fail at high rates,"[/quote] I agree completely -- All you have to do to circumvent age questions is to lie about your age when asked.

| | Well, benna, just exactly what does "low impact" mean, without using the words "low impact" ? If you can't define it then you probably don't know any more than CNN what that means. Microsoft, and other IT people too, are good at throwing around meaningless terms (gobbledegook) |

I hate those ergonomic split keyboards that benna loves -- I tried one at work once and couldn't type on it. The typewriters we learned to use in school had no letters … |

| | This is a simple example of how to delete a line from a text file. In order to do that you have to completely rewrite the file, leaving out the line(s) you want to delete. First open the input file, then open an output file (doesn't matter what filename you …  |
 | >> A string can contain an '\0' before the actual end of the array Yes it can, but that makes it a binary string, not an ascii string, and most string functions in C and C++ will not be able to deal with it. |
| | excellent work. Only two suggestions: 1. fflush(stdin); -- fflush() is guarenteed to only work with output streams. Some compilers allow it for input streams, but that is compiler-specific and will not work on many compilers. 2. In the loop that gets keyboard input you should add a prompt to that … |
