  • Will a CF code run on regular server?

    - by Joann
    I am tasked to integrate a CF code(about 70 lines) into our site then configure it to communicate to another site's server. However, our hosting site is just a typical server without CF support. Will the code run? All I know is that CF is Adobe's version of PHP and ASP. I have no experience coding it. Could you please enlighten me? From what I gathered from the internet, you have to have a CF server in order to run a CF code but the resources seem scarce. I just need someone knowledgeable to verify...

  • How to do relative imports in Python?

    - by Joril
    Imagine this directory structure: app/ __init__.py sub1/ __init__.py mod1.py sub2/ __init__.py mod2.py I'm coding mod1, and I need to import something from mod2. How should I do it? I tried from ..sub2 import mod2 but I'm getting an "Attempted relative import in non-package". I googled around but found only "sys.path manipulation" hacks. Isn't there a clean way? Edit: all my __init__.py's are currently empty Edit2: I'm trying to do this because sub2 contains classes that are shared across sub packages (sub1, subX, etc.). Edit3: The behaviour I'm looking for is the same as described in PEP 366 (thanks John B)

  • display HTML content from database with formatting in it

    - by Gaurav Sharma
    Hi all, I have used wmd-editor in my cakephp v1.3 application. The config which I have written is as follows: wmd_options = { output: "HTML", lineLength: 40, buttons: "bold italic | link blockquote code image | ol ul heading hr", autostart: true }; When I submit the form the HTML in the wmd enabled textarea is saved in the database with htmlentities() done to the text then I am displaying it with html_entity_decode() method. but the text is displayed as it is including the HTML coding like this <p><strong>hello dear friends</strong></p>\n\n<pre><code>I want to make sure that everything that you type is visible clearly.\nadasfafas\n</code></pre>\n\n<blockquote>\n <p>sadgsagasdgxcbxcbxc</p>\n</blockquote>\n\n<p><em>sadfgsgasdsgasgs</em></p>\n\n<p><b><a href="http://kumu.in">this is the link</a></b></p> Please help me solve this problem Thanks

  • Weird use of generics

    - by Karl Trumstedt
    After a bit of programming one of my classes used generics in a way I never seen before. I would like some opinions of this, if it's bad coding or not. abstract class Base<T> : where T : Base<T> { // omitted methods and properties. virtual void CopyTo(T instance) { /*code*/ } } class Derived : Base<Derived> { override void CopyTo(Derived instance) { base.CopyTo(instance); // copy remaining stuff here } } is this an OK use of generics or not? I'm mostly thinking about the constraint to "itself". I sometimes feel like generics can "explode" to other classes where I use the Base class.

  • Should I be so enthusiastic about Groovy?

    - by rukoche
    I'm currently working on my project which consists of front and back-end written in PHP and desktop app written in Java, and that's what the plan was before I discovered Groovy and later on Grails. Now after rewriting my desktop client and sketching some back-end functionality in Groovy I'm considering to drop PHP altogether in favor of Groovy (although I haven't played around with Grails yet.) For me it just looks like coding in Groovy is as simple as in PHP, but with lots of extra sugar and awesomeness of Java libraries. Comparing those two may sound awkward, but hey I'm an amateur ;) Finally to my question, from the looks of it most of the articles/blog posts about Groovy I can find is awfully outdated. Am I missing some reason why it's not so popular and which will crush my enthusiasm to bits? :D

  • Are all the system's floating points operations the same?

    - by Jj
    We're making this web app in PHP and when working in the reports we have Excel files to compare our results to make sure our coding is doing the right operations. Now we're running into some differences due floating point arithmetics. We're doing the same divisions and multiplications and running into slightly different numbers, that add up to a notable difference. My question is if Excel is delegating it's floating point arithmetic to the CPU and PHP is also relying in the CPU for it's operations. Or does each application implements its own set of math algorithms?

  • question about select() and range of for loop to read sockets

    - by Fantastic Fourier
    Just a quick question about using select(). I'm using select() to read from multiple sockets. When I looked up examples on how to use select(), a lot of tutorials showed going through for loops and checking for FD_ISSET. The problem I have with those tutorials is that the for loop starts from i = 0. and checks if the bit has been set for the file descriptor i using FD_ISSET. Couldn't the for loop start from say your minfd (just like how you would keep track of maxfd)?? Or am I missing something?? Following link is an example of such for loop (look at the fourth example that he gives) http://www.developerweb.net/forum/showthread.php?t=2933 If that was the only example out there that used such for loop, I might understand it was a mistake or bad coding but I've seen several examples of such for loop of uselessly going through literally thousands of sockets and I'm convinced I'm missing something. Any comments or inputs are appreciated.

  • What is the most efficient/elegant way to parse a flat table into a tree?

    - by Tomalak
    Assume you have a flat table that stores an ordered tree hierarchy: Id Name ParentId Order 1 'Node 1' 0 10 2 'Node 1.1' 1 10 3 'Node 2' 0 20 4 'Node 1.1.1' 2 10 5 'Node 2.1' 3 10 6 'Node 1.2' 1 20 What minimalistic approach would you use to output that to HTML (or text, for that matter) as a correctly ordered, correctly intended tree? Assume further you only have basic data structures (arrays and hashmaps), no fancy objects with parent/children references, no ORM, no framework, just your two hands. The table is represented as a result set, which can be accessed randomly. Pseudo code or plain English is okay, this is purely a conceptional question. Bonus question: Is there a fundamentally better way to store a tree structure like this in a RDBMS? EDITS AND ADDITIONS To answer one commenter's (Mark Bessey's) question: A root node is not necessary, because it is never going to be displayed anyway. ParentId = 0 is the convention to express "these are top level". The Order column defines how nodes with the same parent are going to be sorted. The "result set" I spoke of can be pictured as an array of hashmaps (to stay in that terminology). For my example was meant to be already there. Some answers go the extra mile and construct it first, but thats okay. The tree can be arbitrarily deep. Each node can have N children. I did not exactly have a "millions of entries" tree in mind, though. Don't mistake my choice of node naming ('Node 1.1.1') for something to rely on. The nodes could equally well be called 'Frank' or 'Bob', no naming structure is implied, this was merely to make it readable. I have posted my own solution so you guys can pull it to pieces.

  • Best Pratice to Implement Secure Remember Me

    - by Yan Cheng CHEOK
    Sometimes, I came across certain web development framework which doesn't provide authentication feature as in Authenication ASP.NET I was wondering what is the security measure needs to be considered, when implementing "Remember Me" login feature, by hand coding? Here are the things I usually did. 1) Store the user name in cookie. The user name are not encrypted. 2) Store a secret key in cookie. The secret key is generated using one way function based on user name. The server will verify secret key against user name, to ensure this user name is not being changed. 3) Use HttpOnly in cookie. http://www.codinghorror.com/blog/2008/08/protecting-your-cookies-httponly.html Any things else I could miss out, which could possible lead a security hole.

  • How to determine whether a .NET exception is being handled?

    - by romkyns
    We're investigating a coding pattern in C# in which we'd like to use a "using" clause with a special class, whose Dispose() method does different things depending on whether the "using" body was exited normally or with an exception. To the best of my understanding, the CLR keeps track of the current exception being handled until it's been consumed by a "catch" handler. However it's not entirely clear whether this information is exposed in any way for the code to access. Do you know whether it is, and if so, how to access it? For example: using (var x = new MyObject()) { x.DoSomething(); x.DoMoreThings(); } class MyObject : IDisposable { public void Dispose() { if (ExceptionIsBeingHandled) Rollback(); else Commit(); } } This looks almost like System.Transactions.TransactionScope, except that success/failure is not determined by a call to x.Complete(), but rather based on whether the using body was exited normally.

  • Should image size be defined in the img tag height/width attributes or in CSS?

    - by Benjamin Manns
    Is it better coding practice to define an images size in the img tag's width and height attributes? <img src="images/academia_vs_business.png" width="740" height="382" alt="" /> Or in the CSS style with width/height? <img src="images/academia_vs_business.png" style="width:740px; height:382px;" alt="" /> Or both? <img src="images/academia_vs_business.png" width="740" height="382" style="width:740px; height:382px" alt="" />

  • Avoiding Multiple Dialog Calls with htaccess

    - by Jeffrey J Weimer
    OK, I'm new to this, so pardon if the question is already a FAQ. Searching multiple places still leaves me dumbfounded. I have a Web site generated with iWeb09/Mac hosting on an ISP. To secure certain pages, I am trying to set up .htaccess + .htpasswd files. The basic directory structure is ... Main index.html Images.html Images (some css, js stuff) Media Image01 Image01.jpeg ... Image02 Image02.jpeg ... I want to password protect access to the Images directory and all the files therein. The index.html file has a link to the Images.html file that contains the layout for the files in the Images directory. I have put a basic .htaccess file at the Main level that restricts access via ... <Files "Images.html"> AuthType Basic AuthName "Images" AuthUserFile /Main/.htpasswd AuthGroupFile /dev/null Require valid-user </Files> I have then created a valid .htpasswd file. All works at the start, however after the first call to set up the Images.html page, the secure login prompt is displayed multiple times, presumably once for every sub-sub-directory Images/Media/ImageXX (with multiple sub-directories, I just give up after two or three times). I have also tried placing the .htaccess file inside the Images directory with the same problem. Recommendations I have seen suggest a better convention is needed in the basic .htaccess file itself. Alternatively, perhaps a companion .htaccess is needed in the Images directory. So, how do I fix this problem? -- JJW

  • Change panel "visible" property on MasterPage from Child pages

    - by Vitor Reis
    I want to show some panel with a label that is located on a MasterPage from inside it's child pages.. I already did the coding on the MasterPage: public class MyMaster : MasterPage { public void ShowPanel(string pMessage) { labelInside.Text = pMessage; myPanel.visible = true; } } Then I make the calls from child pages: public void ShowPanel(string pMessage) { MyMaster masterPage = this.Master as MyMaster; masterPage.ShowPanel(pMessage); } This "works" ok, but it won't show nothing, since I need the page to be "refreshed" in an "ajax-way" like an UpdatePanel, which I can't use because the Trigger is in another page, right? I really need this to work.. even if you have another completely different way to do this, I would appreciate.

  • C# progress bar not synced with download (WebClient class)

    - by dominiquel
    Hi, I am coding a system which has a small FTP module included inside, it's not the main feature at all, but needed... I must link the progressbar with the WebClient class event DownloadProgressChangedEventHandler and AsyncCompletedEventHandler, the progressbar increment is ok, and the ASyncCompletedEventHandler launch a MessageBox (as intended), the problem is that the progress bar see to load too slow... problem : My MessageBox pop at 100% (launched by the event handler), BUT when the MessageBox pop my progress bar is only at +-80% (but the .VALUE is really 100), the first though I had was that they have added a "smooth" effect in Windows Vista which slow down the progressbar relatively to it's true value. If any of you have experienced the same problem thanks for your help.

  • URL naming conventions

    - by LookitsPuck
    So, this may be a can of worms. But I'm curious what your practices are? For example, let's say your website consists of the following needs (very basic): A landing page An information page for an event (static) A listing of places for that event (dynamic) An information page for each place With that said, how would you design your URLs? Typically, I'd do something like the following: www.domain.com/ - landing page [also accessible via www.domain.com/home] www.domain.com/event - event information page www.domain.com/places - listing of all places www.domain.com/places/{id} - place information page Now, here's a question. Just grammatically speaking, I have a hangup of referring to a given place in a url as being plural. Shouldn't it make more sense to go with this: www.domain.com/place/{id} as opposed to www.domain.com/places/{id} In some frameworks, you have a convention to follow (for example, ASP.NET MVC) by default. Yes, you can define custom routes to have /place/{id} route to the PlacesController. However, I'm just trying to keep this a bit abstract in discussion. With that being said, let's see for instance on another page of your site, you have a link, that when clicked, would open a modal popup populated with place information. Where you place that information? We could go with something like this: www.domain.com/ajax/places/{id} OR www.domain.com/places/{id} and serve based on the request header (that is, if requesting JSON, return JSON?}. Finally, for SEO reasons, typically I use a slug associated with a given resource. So, something like such: www.domain.com/ajax/places/{id}/london Where london is only there to add decoration to the link for SEO reasons. Is this sound? I ask all of these questions, because these are practices that I've been using for awhile, and I'd just like to see what other developers are doing or if I'm approaching things incorrectly. Thanks!

  • Python: Get items at depth? (set library?)

    - by Mark
    I have a nested list something like this: PLACES = ( ('CA', 'Canada', ( ('AB', 'Alberta'), ('BC', 'British Columbia' ( ('van', 'Vancouver'), ), ... )), ('US', 'United States', ( ('AL', 'Alabama'), ('AK', 'Alaska'), ... I need to retrieve some data out of it. If depth is 0 I need to retrieve all the countries (and their codes), if depth == 1, I need to retrieve all the states/provinces, if depth == 2 I need to retrieve all the cities... and so forth. Is there some set library for doing stuff like this? Or can someone point me in the right direction? I started coding up a solution only to realize it wouldn't work for levels deeper than 1 because you have to go in and out of each list...

  • How to implement a good system for login/out into a webapp

    - by Brandon Wang
    I am one of the developers at PassPad, a secure password generator and username storage system. We're still working on it, but I have a few questions on the best way to implement a secure login/out system. Right now, what we plan on doing is to have the login system save a cookie with the username and a session key, and that's all that serves as authentication. The server verifies the two to match. Upon login/out a new key is created. This is a security-related webapp and while we don't actually store any information that might make the user queasy, because it is security-oriented it makes it a necessity for us to at least appear secure in a way that the user would be happy with. Is there a better way to implement a login/out system in PHP? Preferably it won't take too much coding time or server resources. Is there anything else I need to implement, like brute-force protection, etc? How would I go about that?

  • What happened to the .NET version definition with v4.0?

    - by Tom Tresansky
    I'm building a C# class library, and using the beta 2 of Visual Web Developer/Visual C# 2010. I'm trying to save information about what version of .NET the library was built under. In the past, I was able to use this: // What version of .net was it built under? #if NET_1_0 public const string NETFrameworkVersion = ".NET 1.0"; #elif NET_1_1 public const string NETFrameworkVersion = ".NET 1.1"; #elif NET_2_0 public const string NETFrameworkVersion = ".NET 2.0"; #elif NET_3_5 public const string NETFrameworkVersion = ".NET 3.5"; #else public const string NETFrameworkVersion = ".NET version unknown"; #endif So I figured I could just add: #elif NET_4_0 public const string NETFrameworkVersion = ".NET 4.0"; Now, in Project-Properties, my target Framework is ".NET Framework 4". If I check: Assembly.GetExecutingAssembly().ImageRuntimeVersion I can see my runtime version is v4.0.21006 (so I know I have .NET 4.0 installed on my CPU). I naturally expect to see that my NETFrameworkVersion variable holds ".NET 4.0". It does not. It holds ".NET version unknown". So my question is, why is NET_4_0 not defined? Did the naming convention change? Is there some simple other way to determine .NET framework build version in versions 3.5?

  • what are the advantages of C# over Python

    - by Matt
    I like Python mostly for the great portability and the ease of coding, but I was wondering, what are some of the advantages that C# has over Python? The reason I ask is that one of my friends runs a private server for an online game (UO), and he offered to make me a dev if I wanted, but the software for the server is all written in C#. I'd love to do this, but I don't really have time to do multiple languages, and I was just after a few more reasons to justify taking C# over Python to myself. I'm doing this all self-taught as a hobby, btw

  • How can I get JavaDoc into a JunitReport?

    - by benklaasen
    Hi - I'm a tester, with some Java and plenty of bash coding experience. My team is building an automated functional test harness using JUnit 4 and ant. Testers write automated tests in Java and use JavaDoc to document these tests. We're using ant's JunitReport task to generate our test result reports. This works superbly for reporting. What we're missing, however, is a way to combine those JavaDoc free-text descriptions of what the test does along with the JunitReport results. My question is, what's involved to get the JavaDoc into the JunitReport output? I'd like to be able to inject the JavaDoc for a given test method into the JunitReport at the level of each method result. regards Ben
