 | I'm guessing that [inlinecode]randNumGen->Next()[/inlinecode] returns a number, correct? What you'll need to do is convert this into a string before assigning [inlinecode]textBox1->Text[/inlinecode] to it. |
 | >why not combine all linux and unix questions into one category? Well, for one thing, I like to have shell scripting questions separated from Linux "help" questions. And having distro choice discussions separate from software installations is also a nice feature. The only forum that really doesn't serve a purpose … |
| | >But are not there kernels the same? No. Although the Vista kernel does use sections of the XP kernel, huge amounts of new code have been added to the Vista kernel (such as security enhancements), making it close to impossible to apply many of the features of Vista to Windows … |
| | >clientRequest.push_back(????); Well, I guess you could just create a temporary instance of [inlinecode]Client[/inlinecode] that you continually fill with data and push onto the vector. It'd be much easier to add a new element into the vector with [inlinecode]insert[/inlinecode], and then just fill in the data directly: [code=cplusplus] clientRequest[i].aa = xx; … |
 | Re: Mark as read I don't know if this helps, but you can mark a forum read by double-clicking the yellow folder that's beside the name of a forum. At least it saves you the trouble of visiting each individual forum.  |
| | X11 is included as an installation option when installing Mac OS X. If you choose not to install it, the only way you can get X11 is by installing a third party application like you did. It's generally better to use Apple's implementation of it, so the next time you … |
| | >Anybody know of any online c++ "dictionaries" There isn't any complete documentation of the language as far as I know, but there are a number of sites that document quite a number of C++'s functions. One such site is [URL="http://www.cplusplus.com"]www.cplusplus.com[/URL] . However, using some documentation is at best, a poor … |
| | Firefox is distributed on a disk image, which is basically a compressed file. When you double-click it, you extract it into the memory. (That "Applications folder" you were wondering about is actually a watermark that you see when you open the disk image, it doesn't do anything.) Now you need … |

| | [quote=Salem;368689] You're reversing a string "in place", so the real answer is in string. printf("%s",string); [code] if ( length > 1 ) { ptr[0]=ptr[length-1]; reverse(ptr+1,length-2); } [/code][/quote] Just a thought, shouldn't you be saving the contents of [inlinecode]ptr[0][/inlinecode] to a temporary variable, and then copying this back to [inlinecode]ptr[length-1][/inlinecode]?  |
 | I always do it from the command line so I can see what's happening. [code]# wine notepad.exe[/code] Or if it's installed on your fake "C drive", you would do it like this: [code]# wine "c:\program files\etc"[/code] |
| | [URL]http://msdn2.microsoft.com/en-us/library/ms532309.aspx[/URL] The answer is pretty clear. [quote][I]hInstance[/I][in][INDENT]Handle to the instance of the module whose executable file contains the bitmap to be loaded.[/INDENT][/quote]Since you're not passing a valid application instance, it's highly unlikely it's going to give you valid handle. |

| | Re: OpenGL and Glut >Is using Glut with OpenGL still popular and recommended? Pretty much. GLUT certainly isn't dead, is a good way to make OpenGL programs portable with very little code, and it's a great way to start out with 3D graphics programming. As you gain more experience and your programs become more … |
 | Well, lo and behold, it's May 15th. [quote=sk8ndestroy14;367108]Well it's on topic a little because I made a post that was on topic but it didn't show and that's happened to me once before.[/quote] Good point. That justifies you for bringing the thread off-topic. I'm glad we all make so much …  |

| | Re: average array Did you even change anything? Look at it this way: you need to grab the user's input [I]before[/I] the while loop, so that you can see if it was invalid or not. Then if it's invalid, the while loop kicks in, which keeps grabbing input until it's valid. Inside the …  |
| | Re: help pls... >Anybody who knows how to save a file to [U]/usr/include[/U] in the terminal? Uh, yeah. Just use the [inlinecode]cp[/inlinecode] or [inlinecode]mv[/inlinecode] command. With root (administrator) privileges, of course. >Suppose I will save a file named hello.h to the said directory If you save it there, then well, it's there. >what … |
| | You should definitely deallocate any memory you allocate. Otherwise you'll experience those awful memory leaks. And why in the world are you using [inlinecode]malloc[/inlinecode] for allocating the memory, and [inlinecode]delete[/inlinecode] for deallocating? That's a bug right there. When in C++, do like the C++'ers do, that is, use [inlinecode]new[/inlinecode] and … |

Here's some links that I have lying around: [URL]http://faq.cprogramming.com/cgi-bin/smartfaq.cgi?answer=1052863818&id=1043284351[/URL] [URL]http://faq.cprogramming.com/cgi-bin/smartfaq.cgi?answer=1044841143&id=1043284376[/URL] [URL]http://www.devx.com/tips/Tip/14447[/URL] >char *accept(); Yikes.

| | Re: Network lib [quote=~s.o.s~;362234]Maybe something [URL="http://curl.haxx.se/libcurl/"]like this[/URL], though I am not very sure.[/quote] Nah, I think Curl is a bit too limited for the OP's purposes. Curl was built more for file transfer, not port scanning. Can't think of much, however at least look for something that's C++ based, such as this wrapper … |

It just makes sense. >cout endl; There's … |
| | Wow -- it seems like you're way over-complicating the whole procedure. Just make a loop like AD mentioned, and then use a stringstream to split up the words: [code=cplusplus] // loop... std::istringstream iss(line); iss >> lastName; iss >> firstName; // another loop to extract 10 scores, but you get the … |
