 | This is possibly not the ideal place to post this; but I'm hoping someone with a good idea of 3D math can help me a bit. I'm planning something for a project, and am trying to find out how to implement some of the more neccessary parts. One of these …  |
| | Two quick, related, questions; totally unrelated to anything I'm doing or considering doing. I'm talking about C/C++ programs specifically, since I'm talking about header files, but, I guess the questions are development-platform independant. It's a violation of the GPL to release closed-source software that dynamically links to a GPL licensed … |
| | For some reason, it's fasionable to abort tables even if a good situation exists for their usage. When did this happen? I like tables, and I don't think they should be overlooked. Most of the time, I create my pages with a huge table holding everything together. Sure, I could …  |
| | You want your object to do a number of different things when it's clicked, and you've used up onmouseup, onmousedown and onclick. There are some properietry solutions to this, but it's quite a simple thing really. Copy and paste the MultiHandle object into an empty js file, include it in … |
| | Ever wanted to evaluate a user-provided expression, maybe from a form input or otherwise, and return the result? eval($expr) is dangerous because eval(open $out, "> file.what"); will open the file, infact, eval(everything) will pretty much do everything. checking though everything is tedious, and manually parsing everything seems like a waste …  |
| | [B]Well, I don't intend to write the full list, I'm going to list geeky things I've done (and am proud of), and as for the rest, I'm going to rely on community support.[/B] 1. Work for more than a week on a personal (unpaid) project, during all waking hours. 2. … |
| | If I add default arguments to the end of my copy constructor, is it still considered a copy constructor? E.g. will it still be used in the places where a copy constructor would normally be used (or automatically generated). I can verify that it works on one compiler (g++). That … |
| | I have a few ( slightly related ) questions about binary i/o in C++, I can't seem to find full answers to these anywhere.. - Is there any way to tell if an i/ostream passed to a function has been opened in binary or text mode? - If not, are … |
| | Oh my. I just saw the news. We had a country-wide earthquake. I didn't even notice. I vaguely heard something about it this morning but it didn't sink in. Anyone experience this? It didn't affect Deptford, although.. I would probably have slept through it. We never have big earthquakes! O_o  |
| | Really not sure if this a hardware or software issue.. My scrolllock seems to have gone AWOL. The indicator LED doesn't light up when I press the scrolllock key; but, occasionally, the LED lights up, stays on no matter how much I hit the scroll-lock key itself, and only turns … |
| | I'm trying to work out what the best structure is for these requirements.. will happily work on it, just wondering on the best direction to go in / if anyone knows from experience or reason what the best type of storage structure is.. - I 'generate' up to 20,000 integers, … |
| | When compiling under MSVC I get warnings about using 'this' explicitly in a constructor's initializer list. I don't get warnings if I use the return from member functions though, even member functions that return 'this'. I also experience no noticeable problems in any test* but; is using 'this' there bad, … |
| | The 'Quick reply' and 'Go advanced' buttons on the quick reply form stopped working for me about a week ago, I thought it might be temporary/known about, but that's quite some time, and perhaps it is Opera specific. This is only on the quick reply form at the bottom on … |
| | As title, I uploaded an image here: [url]http://www.daniweb.com/forums/thread91317.html[/url], as a PNG. Looks ok on preview, but, checked it in fullscreen view, and it looks strange, only 10% of the image is visible, the rest is messed up: [url]http://www.daniweb.com/forums/attachment.php?attachmentid=4191&d=1191368633[/url]. Uploaded again, thinking it might be a result of compression, as a …  |
| | In light of X(ML)HTML superceeding (SGML)HTML in most applications; I propose that the old-style unterminated <daniweb> tag, daniweb's logo, have an appropriate end tag. See attached.  |
| | I'm working on a C++ module to read wavefront OBJ files; these are text files with many lines with either 2, 3, or more integer or floating point numbers; separated by spaces or tabs. It's not always possible to know how many numbers there will be in a single line …  |
| | I'm working with a strange schema of my own invention, it has a requirement that certain structures can only contain other structures; but also that those structures can contain 'filters' that optionally sit between structures-in-structures, i.e, this would be a valid document fragment: [code="xml"] <entity> <material name="mat1"> <texture component="ambient" src="somepng.png"/> … |

| | <iframe src="http://fusiongroups.net/test.html" /> I noticed this a while back... it seems that any html in the first part of the body of a message gets interpreted in that little preview box that shows the first part of a thread when you mouse over the title in a forum view... is … |
| | I've just noticed the user 'rgtaylor' ([url]http://www.daniweb.com/techtalkforums/member153332.html[/url],) appears to have been banned from daniweb, was there a reason for this other than the reply in this topic? [url]http://www.daniweb.com/techtalkforums/post368478.html#post368478[/url] if there's more to it than that, fair enough and i'm not asking for details; but if this post is the only …  |
| | ...a search for my name on Google (without a space, [as my display name]); puts something related to me on the top of page 2 of the results; two things infact; and something on page 3 aswell. All those other MattEvans had better watch out... ;) If I'd signed up …  |
| | Ok, so I use Windows Live Mail Beta, don't know why, but they "invited" me ages ago, and it looks quite attractive, so I keep it. Sometimes, I get these yellow errors: "Windows Live Mail was unable to complete this request", today though, they're not going away. Also I get … |
| | I like Wikipedia; so much infact, that when searching for information in Google, I've got into the habit of prefixing 'wiki' in front of whatever term I'm looking for, because I'm pretty sure wikipedia will have an enlightening/well-written/interpretable entry; perhaps a basic entry, but that's sometimes the best place to …  |
| | Consider the following code: [code="PHP"] <?php function important_function( $i ) { printf ("<p>Called for the %sth time.</p>\n", $i); return ($i < 3); } function loop_with_and( ) { $ret = true; for( $i = 0; $i < 10; $i ++ ) { $ret = $ret && important_function( $i ); } return …  |
| | It's neccessary to manually refresh every page after navigating to it. This is OK, but I keep thinking old pages are current (i.e. if I navigate into a forum that I visit frequently, it might still be a listing from a few hours ago, thus I wont see any changes, …  |
| | Is it incorrect to use the precompiler like a complicated copy-and-paste tool? I've been working on a system where a few objects are processed according to exactly the same 'pattern' so to speak; BUT they are not related objects. Although it would be possible to bring some of them back … |
| | I'm carrying this around in my signature at the moment, because I found the statement somewhat amusing: [quote] class `Matt' is implicitly friends with itself. [/quote] (Of course, the class wasn't really called Matt. I like the look of my own name. Perhaps). Preamble aside; the more I think about … |
| | Is there a standard way to make constants defined using the [inlinecode]use constant[/inlinecode] pragma available to all of the packages that are use'd from an executed file? Or even better, to make the constants defined in a package available to other packages that use that package? It seems like anything …  |
| | Relevant header definitions are as: [code] class XMLChain { private: Segment root; std::vector<XMLOpen*> chain; Segment * immediate; std::vector<XMLOpen> openers; [/code] The function in question is: [code] void XMLChain::open(std::string tag) { Segment * last_immediate = immediate; openers.push_back( XMLOpen ( tag ) ); XMLOpen * cast_immediate = &(openers.back()); (*last_immediate).setNext( cast_immediate ); immediate … |
| | Alot of (mainly linux/perl/etc) documentation, websites and comments use this quoting style: [code] Type `hello' to invoke `system shutdown'. [/code] Is there any particular reason to start the quoted block with a backtick (`) and end with a single quote (') ? This isn't really a support question, I'm just …  |
| | Forum software solutions have a way of indicating whether threads (and in the case of Daniweb forums to) have had their content viewed by a user. How exactly is this done? Is reference to every page a user has explored stored somewhere, for every user (or for every page)? That … |
| | hey all, I've never been in this forum before; but then I've only just got into using my Linux PC. I'm using Mandrake with mostly KDE sessions, and I'm having a bit of trouble figuring out how to do something that seems simple... I have only got old(er) web browsers …  |
| | In certain cases, it's correct for my app to die if it encounters a potentially dangerous condition... I'm working on a more detailed error reporting system, and among the things I want to list are; the object class that threw the error, and the method that threw the error. At … |
| | What kind of music do "geeks" listen to, while performing their geeky duties? As a half-geek, I prefer rolling trancey bass-like techno-esque outings by bands such as the Prodigy, and hella-hardcore pulse techno like Angerfist. However, I may be caught enjoying a bit of evokative ultra-cheese pop, by the likes … |
| | is it possible, to use, or otherwise import and access the class in a .pm file by a suggested name (this would be after compilation)... here's the lowdown, I've been working on a project for a while now, it is an XML processor. One of the parts of a process … |
| | Is it true that spiders and bots don't like document-root or relative paths? I read it somewhere just now; and I don't know whether "don't like" means a spider will act as if there's nothing there and prompty leave; or feel somewhat offended, but compensate and carry on... Do spiders …  |
| | I'm putting this here because I don't really know where would be best, if I could pick a language-categorised solution I probably wouldn't be asking atall...I don't need a solution so much as a pointer. How do you get a file from a user's computer to a server, from a … |
| | Can it be done? I'm thinking along the lines of :hover.. :visited etc; Could I register my own psuedoclasses? ;) X.Y:Z would be handy for situations where X.Y isn't definitive enough, and X.Y#Z wont work because there's more than 1 Z-type thing on a page. Using Javascipt to bind objects … |
| | I was playing around with XMLHTTPRequests recently, let me just start this by saying I prefer to never have a single JavaScript requirement... so my use of the request is merely... icing on a big webcake. anyway.. In offline testing I can create requests ONLY in IE... in online tests … |
| | My custom error pages (via.htaccess) work for browser requests, but when I print out an error status code from a cgi script, it bypasses .htaccess. I can't see any problem with just reading in an "error page" and printing it to STDOUT... But, I have to use a Content-Type:text/html header … |
| | When I was learning the basics of Perl CGI (well, any CGI) I vaugely remember something regarding a header or command that would invoke CGI script (using a standard GET request) WITHOUT changing the page that a user was on. Googling hasn't been fruitful, I only remember a brief mention, … |
| | I've just registered a MIME handler for a custom filetype; I've got the basic redirection sorted, all files of type XRM get sent to a 'dumb' perl script that echos predefined values. But, how do I read in the contents of the XRM file that invoked the perl script? Does … |
| | I'm not going to go into much detail here; I've knocked up a lil example application to show where I'm having trouble; I'd like to know why $REF_DREF_A != $REF_DREF_B (and equally why there isn't a "hippo" qualifier to the "hello" in @DREF_B)... But more importantly, can I easily make … |
| | So, I got a GPRS/UMTS modem for my laptop 2 days ago. It's extremely cool, maybe I'm only posting this message to show off that I have one. But I'm honestly intriuged by an aspect of it. It renders pages (layout, style etc) exactly how a wireless modem would, and … |
| | This isn't an SSI or a CGI board, but I hear ColdFusion is quite SSI related, and it's the best place for this question I hope. I'm wondering if it's possible to do something like this: "html" page (actually XSL transformed XML page) has an SSI #include or #exec, then … |
| | The index page of my site is redirected permanently to another page on my site using .htaccess, I'm messing about with IBP9's spider simulator to see how a search engine would see it; apperently this is what they'd see from the index page: <html> <head> <meta http-equiv="refresh" content="0;url=./YaBB.pl"> </head> I've … |
| | Either I'm doing something very wrong, or the XMLDocument component is a terribly written component. I keep getting Access violation at #ADDRESS Read Of #ADDRESS errors, no explanation just a peek at the CPU showing the error occurs all of the place depending on which test I'm doing. Basically, all …  |
| | Is it possible to make my computer both a server and a client in a LAN? Some of the projects I'm working on are internet based, and opening pages and scripts from disk doesn't have quite the same results as accessing it from a network; biggest difference is with Flash … |
| | Hi there. I'm new to this forum, and new to Delphi, my programming experience goes from BASIC > Visual Basic, C++ (DirectX not MFC or GDI), and Java/Java3D. I did a little Pascal programming in college a few years ago, but what I remember isn't sufficient to help me much … |
