Remove Filter  | This is essentially a really long question **If I were to create a function without calling it's execution. Does PHP initialize it anyhow or is the entire function ignored entirely without even bothering to read it?** Another way to put it: **Is there any execution difference between code that does …  |
| | Since I totally F'd up entire topic. [Over here](https://www.daniweb.com/programming/software-development/threads/502281/verify-if-data-sent-by-servers-how-do-bigger-companies-do-that), where nobody has ever known what I meant, until I realized that I said a lot of things that didn't make sense at all, nor I could make up any reasonable statements from smart people out there. By suggestion of said … |
| | I know that it's possible for speakers to repeat whatever sound comes into microphone. But, now I'm thinking. When I speak on Skype/TeamSpeak (VoIP software), would it be possible for me, to select audiofile and play it as if it was sent through microphone? To send music through my "microphone" … |
| | Since I English no good. I picture send you. How do I do? Just kidding. How could I put div through another divs perimeter by 20 pixels, 100 pixels or perfectly within them both? I saw that on a website, but they have ultra-spaghetti code with 50 billion wrappers (no … |
| | According to [this](https://github.com/nwjs/nw.js/wiki/Protect-JavaScript-source-code-with-v8-snapshot) link. V8 Snapshot of your JavaScript file, makes it somehow more protected. Notice: This is **V8 Snapshot** not just **V8**. Now I have couple questions, if you're familiar with this technology: 1) Is there a way to obfuscate it more? There are .NET obfuscators, there are C++ … |
| | https://jsfiddle.net/fg1mfn2m/2/ I don't understand jQuery. Or any programming language for that matter. I'm trying to get to resize a child of a div, as soon as said DIV is clicked.

| | https://jsfiddle.net/cr72vqhb/1/ Follow 2 scenario's. First Scenario: Click on **client-side**, get message, menu slides out. Click on **server-side**, get message, first menu hides, second slides out. Perfect, right? # Hard refresh the Fiddle # Second Scenario: Click on **server-side**, nothing. Absolutely nothing. It's as if I mistyped the selector. Why is … |
| | As soon as I find out exact manner of communication between the server and the software. I realized how easy it is to use programs to intercept it, analyze it and then send malicious (or rather illegal) query through. So. I was wondering is there a way to make sure … |

| | If I wrote a program which would `Console.WriteLine()` a base64 code, like an easter egg ("a hidden secret" in gaming jargon) or something, for example string EasterEgg = "dGhlYmlnc2VjcmV0"; Console.WriteLine(b64d(EasterEgg)); And I would let a good obfuscator run through it. Now I know that crackers with enough time and knowledge … |

So far I understood: *Particular questions that I'm asking are written in Italic hence Bold texts are not visible with this font.* "IPS is way better with color precision and contrast. But has problems with "ghosting", it generally looks like someone hasn't compiled video well. …  |
| | Website is exclusively built with `.click()`, `onclick=""` and alikes. I'd like to use a plugin that there is out in the world, which would allow me to use custom scrollbar to scroll content of a lengthy `<div>`. I've tested about 6, whom 1 didn't work (maybe I just can't read), … |

| | It might be obvious, but I can't seem to understand it. So don't laugh. Let's assume this scenario. My website has 5 themes, there are 5 buttons. Clicking each button changes theme respectively and uniquely. I use JavaScript to do that, so I set name of theme in a cookie, … |
| | Not so long time ago, I asked you for help with `preg_match()`. Pritaeas gave me nice answer and Cereal showed me nice webpage where I could try out the latest queries, live. The query provided seems to be working on the website granted, but not on my project. 4 out …  |
| | Is there a way to grab strings that match patterns `--*--` and `++*++` (two seperate queries) where `*` is a wildcard and `--`, `++`, are criteria to meet. I'd like to write matches within variable fully, like `--daniweb.com--` and `++this just an example++`. `preg_match()` provides solution on alphanumerical identities. And … |

I have double do-while in there, however I can't modify variables from within that loop, they simply don't affect the variable anyhow. I have tried a lot of solutions, including those about `$GLOBALS` … |
| | `$allowedForUniversalUsage = htmlEntities($_GET["potentially_super_malicious_code"], ENT_QUOTES);` Does script above help me against XSS and MySQLi injection? My thoughts would be: **Protection against XSS: Yes** I mean. XSS means that someone would be able to input code, which will be shown publicly and will be executed, the `htmlEntities()`. It converts actual code into … |
| | For as long as DaniWeb allows us to edit posts, can we also edit the title, move the thread and remove the post (if we magically found our answers on 69th page of Google)? This would help stopping in forcing me to report my own topic to edit title or … |

| | In forum: "Web Development Discussion Community". I sought for unanswered topics, one of them being [this one](https://www.daniweb.com/web-development/aspnet/threads/498270/mvc). What's weird is in the [forum view](https://www.daniweb.com/web-development/31), the content of post mentions *Create a realtime notification in mvc aplication. It can be an alert notification.*, while the [topic itself](https://www.daniweb.com/web-development/aspnet/threads/498270/mvc) says *How to create …  |

But I don't want any direct access to `/core/adm/index.php`, I want it to be accessed only by AJAX request from `/admin.php`. Is there a way to … |

| | Imagine this, (names made up or/and don't apply to current situation, names used/imagined only for purposes of explaination) There's server called `daniweb.com`, it's an API server. You can get quite chunk of data out of it. But for some reason, the one who orders the project, demands that we request … |
| | I have been cuddling with OOP programming. JavaScript seemed like a good start. I went to w3schools.com. function person(first, last, age, eye) { this.firstName = first; this.lastName = last; this.age = age; this.eyeColor = eye; this.name = function() { return this.firstName + " " + this.lastName this.capitalize = function() { … |

| | I don't trust my code. I really don't. I always have a feeling that something is wrong with it. Every variable looks like an enemy. Every loop, unfinished condition. Every input, possible injection. I'm kinda paranoid so to say. There's many white hat hackers out there which could make buck … |
| | I get exactly this same error as [this Sir over here](http://askubuntu.com/questions/111959/what-is-a-bad-quality-package). There is solution given: cd ~/Downloads sudo dpkg -i *.deb sudo apt-get install -f What worries me more is that Brackets (by Adobe), Opera (by Opera), Chrome (by Google) are also considered bad quality. I could understand that sometimes … |

| | Recently I got interested into dynamic execution of scripts. That is, user clicks the button and the JavaScript part (or any other library attached to it) will send a request to a file with `$_GET[]` or `$_POST[]` data. Then PHP (preference) would execute the function or anything that it has … |
