• Good Learning Method for Objective-C?

  - by Josh Kahane

  Hi I know this must be asked a millions times and can't be easy to answer as there is o definitive method, but any help would be appreciated, thanks. I have been playing around with all sorts of things in Xcode and with Objective-C, however I can't seem to find a good way of learning things in an efficient way. I have bought the book 'Programming in Objective-C 2.0' and its great but just lays down the basics it seems. I want to learn in the 2D game development direction, then of course 3D after nailing that, if thats the right thing to do? I am 17 currently in year 13, last year of school/A Levels and am almost definitely taking a gap year. Any good, well known reputable courses online or offline (real world)? This is my first programming language, and I am absolutely serious about learning this. One last question, is when learning things online, I have in the past started building a feature and learning a certain aspect in programming only to find out after adding more its slows down the app or its to inefficient. Is the key to use a certain method in a certain situation (being os many ways to do the same thing) or use any of those methods and refine it in your app to make it run smoothly? Sorry, its hard for me to know when I have little experience, thus far. Sorry for rambling on! I would appreciate any help, thank you!

• JavaScript: input validation in the keydown event

  - by c411

  Hi, I'm attempting to do info validation against user text input in the process of keydown event. The reason that I am trying to validate in the keydown event is because I do not want to display the characters those that are considered to be illegal in the input box at the beginning. The validation I am writing is like this, function validateUserInput(){ var code = this.event.keyCode; if ((code<48||code>57) // numerical &&code!==46 //delete &&code!==8 //back space &&code!==37 // <- arrow &&code!==39) // -> arrow { this.event.preventDefault(); } } I can keep going like this, however I am seeing drawbacks on this implmentation. Those are, for example, Conditional statement become longer and longer when I put more conditions to be examined. keyCodes can be different by browsers. I have to not only check what is not legal but also have to check what are exceptionals. In above examples, delete,backspace, and arrow keys are exceptionals. But the feature that I don't want to lose is having not to display the input in the textarea unless it passes the validation. (In case the user try to put illegal characters in the textarea, nothing should appear at all) That is why I am not doing validation upon keyup event. So my question is, Are there better ways to validate input in keydown event than checking keyCode by keyCode? Are there other ways to capture the user inputs other than keydown event before browser displays it? And a way to put the validation on it? Thanks for the help in advance.

• Wordpress.. Is it a CMS?

  - by madcolor

  I recently was contacted by a client who simply wanted to increase their organic rankings in Google. My approach was to do the following: A) Take them off of their overpriced host and move them to a nicer, cheaper, more feature-rich hosting solution which included a simple Wordpress install. B) Apply a theme to WordPress which followed the look and feel of their existing website. C) Train my client on how to login to their copy of Wordpress and create/manage pages/posts. This took me very little time.. Most of the work in converting asp forms into php and tweaking a theme to fit their design. Now my client is able to create/manage as many pages or posts as they desire. I believe, for this purpose, Worpress was the easiest solution. Would you categorize Wordpress as a CMS? Similar: http://stackoverflow.com/questions/250880/is-there-any-cms-better-than-wordpress-or-should-i-roll-my-own http://stackoverflow.com/questions/1101818/wordpress-as-a-cms-option http://stackoverflow.com/questions/490899/which-cms-to-choose http://stackoverflow.com/questions/629203/is-it-advisable-to-use-wordpress-as-cms-closed http://stackoverflow.com/questions/1451326/is-wordpress-good-for-building-a-large-cms-site-with-many-pages-about-over-100-00 External: http://codex.wordpress.org/User%3ALastnode/Wordpress%5FCMS http://wordpress.org/development/2009/11/wordpress-wins-cms-award/

• WCF Discovery finds endpoint but host is "localhost"

  - by Flo

  I am trying to use the Discovery feature in WCF using http://msdn.microsoft.com/en-us/library/dd456783(v=VS.100).aspx as a starting point. It works fine on my machine, but then I wanted to run the service on a different machine. The service was discovered properly but the hostname of the found service is always "localhost" which is of course not much use. Service Endpoint: var endpointAddress = new EndpointAddress(new UriBuilder { Scheme = Uri.UriSchemeNetTcp, Port = port}.Uri); var endpoint = new ServiceEndpoint(ContractDescription.GetContract(typeof(IServiceInterface)), new NetTcpBinding (), endpointAddress); Client: static EndpointAddress FindServiceAddress<T>() { Stopwatch stopwatch = new Stopwatch(); stopwatch.Start(); DiscoveryClient discoveryClient = new DiscoveryClient(new UdpDiscoveryEndpoint()); // Find endpoints FindResponse findResponse = discoveryClient.Find(new FindCriteria(typeof(T))); Console.WriteLine(string.Format("Searched for {0} seconds. Found {1} Endpoint(s).",stopwatch.ElapsedMilliseconds / 1000,findResponse.Endpoints.Count)); if (findResponse.Endpoints.Count > 0) { return findResponse.Endpoints[0].Address; } return null; } Should I simply set the Host to System.Environment.MachineName?

• Advantages/disadvantages of Python and Ruby

  - by Seburdis

  I know this is going to seem a little like all the other python vs ruby question out there, but I'm not looking specifically to pick one over the other all the time. My question is, essentially, why would you use one language over the other when you are starting a new project? What features does ruby have that python doesn't that would make you decide on it for a given project? What about python over ruby? I was just recently thinking about the differentiation between the two languages because of Jamis Buck's "There is no magic, only awesome" series of articles (4 parts, available here) when I realized I really don't know enough about the two languages to know when to choose one over the other. I'm hoping to get objective answers from people who have experience with both languages, rather than just "python is better, ruby sucks" kind of responses. If you know of a feature in one language that doesn't exist in the other and is great in a certain situation, feel free to chime in and say why you think it's awesome. If you have another language comparable to these that you'd like to suggest pros/cons for, like groovy for example, that would be appreciated too. Some thing I know each language has going for it: Ruby: Awesome metaprogramming Great community Wide selection of Gems Rails Great code readability, usually MacRuby is great for native development on Mac without objc Amazing testing tools (cucumber, rspec, shoulda, autotest, etc.) Python: Whitespace indentation List comprehensions Better functional programming support? Lots of support on linux Easy_install isn't far from gems Great variety of libraries available

• gdb reverse debugging error

  - by Werner

  Hi, i started to try reverse debugging with gdb 7, followin the tutorial: http://www.sourceware.org/gdb/wiki/ProcessRecord/Tutorial and I thought, great! Then I started to debug a real program which gives an error at the end. So I run it with gdb, and I put a breakpoint just before the place I think the error appears. Then I type "record" in order to start to recrd actions for future reverse-debugging. But after some steps I get Process record doesn't support instruction 0xf0d at address 0x2aaaab4c4b4e. Process record: failed to record execution log. Program received signal SIGTRAP, Trace/breakpoint trap. 0x00002aaaab4c4b4e in memcpy () from /lib64/libc.so.6 (gdb) n Single stepping until exit from function memcpy, which has no line number information. Process record doesn't support instruction 0xf0d at address 0x2aaaab4c4b4e. Process record: failed to record execution log. Program received signal SIGABRT, Aborted. 0x00002aaaab4c4b4e in memcpy () from /lib64/libc.so.6 Before I look at in in detail, I wonder if this feature is still buggy, or if I should start to record from the beginning. Where this "record" error happens, just an object is created as a copy of other: Thanks

• How to detect back button or forward button navigation in a silverlight navigation application

  - by parapura rajkumar

  When a Page is navigated to in silverlight you can override this method. protected override void OnNavigatedTo(NavigationEventArgs e) { base.OnNavigatedTo(e); } The NavigationEventArgs has a NavigationMode enumeration which is defined as public enum NavigationMode { New = 0, Back = 1, Forward = 2, Refresh = 3, } But calling e.NavigationMode always throws a NotImplementedException Is there a way in silverlight to detect a page is being navigated to because the user hit the forward/back browser button. What I am trying to achieve is some kind of state that can be preserved when the user hits the back button. For example assume you have a customer page which is showing a list of customers in a datagrid. The user can select a customer and there is a detail view which shows all the orders for that customer. Now within an order item you can click a hyperlink link that takes you to the shipping history of the order which is a separate page. When the user hits the back button I want to go back to the customers page and automatically select the customer he was viewing. Is this possible at all ? I also tried out the fragment navigation feature NavigationService.Navigate(new Uri("#currentcustomerid=" + customer.Id.ToString(), UriKind.Relative)); when the customer selection changes but this adds too many items to the history when the user clicks various customers on the customer page. EDIT There is also an method you can override protected override void OnNavigatingFrom(NavigatingCancelEventArgs e) { } which is the same as handling the NavigationService.Navigating event as indicated by BugFinder's answer. In this method e.NavigationMode always returns New when when you hit the Back or Forward Button. The only time this method returns Back is when you explicitly call NavigationService.GoBack()

• Why are mercurial subrepos behaving as unversioned files in eclipse AND torotoiseHG

  - by noam

  I am trying to use the subrepo feature of mercurial, using the mercurial eclipse plugin\tortoiseHG. These are the steps I took: Created an empty dir /root cloned all repos that I want to be subrepos inside this folder (/root/sub1, /root/sub2) Created and added the .hgsub file in the root repo /root/.hgsub and put all the mappings of the sub repos in it using tortoiseHG, right clicked on /root and selected create repository here again with tortoise, selected all the files inside /root and added them to to the root repo commited the root repo pushed the local root repo into an empty repo I have set up on kiln Then, I pulled the root repo in eclipse, using import-mercurial. Now I see that all the subrepos appear as though they are unversioned (no "orange cylinder" icon next to their corresponding folders in the eclipse file explorer). Furthermore, when I right click on one of the subrepos, I don't get all the hg commands in the "team" menu as I usually get, with root projects - no "pull", "push" etc. Also, when I made a change to a file in a subrepo, and then "committed" the root project, it told me there were no changes found. I see the same behavior also in tortoiseHG - When I am browsing files under /root, the files belonging directly to the root repo have an small icon (a V sign) on them marking they are version controlled, while the subrepos' folders aren't marked as such. Am I doing something wrong, or is it a bug?

• How do I change the color settings in emacs23 running in a terminal console?

  - by Anonymous

  I use xterm and set its appearance in ~/.Xdefaults: XTerm*background: paleTurquoise XTerm*foreground: black I also use emacs, but set its appearance differently in ~/.emacs: (set-background-color "black") (set-foreground-color "yellow") I usually run emacs within the terminal console with emacs -nw, rather than creating a separate X window. For some reason, this doesn't work properly for emacs23; instead, emacs retains the pale turquoise background of my xterm window. Looking at what's new in emacs23, I noted that: ** When running in a new enough xterm (newer than version 242), Emacs asks xterm what the background color is and it sets up faces accordingly for a dark background if needed (the current default is to consider the background light). So it's a feature, not a bug? Anyway, is there some way that I can I tell emacs23 to ignore the xterm background settings when running in console mode, and use the settings in ~/.emacs instead? I'll also note that: Running M-x set-background-color within emacs23 -nw has no effect. It works fine in emacs23 running in a separate X window (without the -nw option). It worked fine in emacs22; and I'm not really sure whether I need to use emacs23... It's not just xterm: the same problem exists with $TERM=cygwin, for example.

• What is the general feeling about reflection extensions in std::type_info?

  - by Evan Teran

  I've noticed that reflection is one feature that developers from other languages find very lacking in c++. For certain applications I can really see why! It is so much easier to write things like an IDE's auto-complete if you had reflection. And certainly serialization APIs would be a world easier if we had it. On the other side, one of the main tenets of c++ is don't pay for what you don't use. Which makes complete sense. That's something I love about c++. But it occurred to me there could be a compromise. Why don't compilers add extensions to the std::type_info structure? There would be no runtime overhead. The binary could end up being larger, but this could be a simple compiler switch to enable/disable and to be honest, if you are really concerned about the space savings, you'll likely disable exceptions and RTTI anyway. Some people cite issues with templates, but the compiler happily generates std::type_info structures for template types already. I can imagine a g++ switch like -fenable-typeinfo-reflection which could become very popular (and mainstream libs like boost/Qt/etc could easily have a check to generate code which uses it if there, in which case the end user would benefit with no more cost than flipping a switch). I don't find this unreasonable since large portable libraries like this already depend on compiler extensions. So why isn't this more common? I imagine that I'm missing something, what are the technical issues with this?

• How can I stop SQL Server Management Studio replacing 'SELECT *' with the column list ?

  - by Ben McIntyre

  SQL Server Mgmt Studio is driving me crazy. If I create a view and SELECT '*' from a table, it's all OK and I can save the view. Looking at the SQL for the view (eg.by scripting a CREATE) reveals that the 'SELECT *' really is saved to the view's SQL. But as soon as I reopen the view using the GUI (right click modify), SELECT * is replaced with a column list of all the columns in the table. How can I stop Management Studio from doing this ? I want my 'SELECT *' to remain just that. Perhaps it's just the difficulty of googling 'SELECT *' that prevented me from finding anything remotely relevant to this (i did put it in double quotes). Please, I am highly experienced in Transact-SQL, so please DON'T give me a lecture on why I shouldn't be using SELECT *. I know all the pros and cons and I do use it at times. It's a language feature, and like all language features can be used for good or evil (I emphatically do NOT agree that it is never appropriate to use it). Edit: I'm giving Marc the answer, since it seems it is not possible to turn this behaviour off. Problem is considered closed. I note that Enterprise Manager did no similar thing. The workaround is to either edit SQL as text, or go to a product other than Managment Studio. Or constantly edit out the column list and replace the * every time you edit a view. Sigh.

• Squid handling of concurrent cache misses

  - by Oliver H-H

  We're using a Squid cache to off-load traffic from our web servers, ie. it's setup as a reverse-proxy responding to inbound requests before they hit our web servers. When we get blitzed with concurrent requests for the same request that's not in the cache, Squid proxies all the requests through to our web ("origin") servers. For us, this behavior isn't ideal: our origin servers gets bogged down trying to fulfill N identical requests concurrently. Instead, we'd like the first request to proxy through to the origin server, the rest of the requests to queue at the Squid layer, and then all be fulfilled by Squid when the origin server has responded to that first request. Does anyone know how to configure Squid to do this? We've read through the documentation multiple times and thoroughly web-searched the topic, but can't figure out how to do it. We use Akamai too and, interestingly, this is its default behavior. (However, Akamai has so many nodes that we still see lots of concurrent requests in certain traffic spike scenarios, even with Akamai's super-node feature enabled.) This behavior is clearly configurable for some other caches, eg. the Ehcache documentation offers the option "Concurrent Cache Misses: A cache miss will cause the filter chain, upstream of the caching filter to be processed. To avoid threads requesting the same key to do useless duplicate work, these threads block behind the first thread." Some folks call this behavior a "blocking cache," since the subsequent concurrent requests block behind the first request until it's fulfilled or timed-out. Thx for looking over my noob question! Oliver

• How does browser know when to prompt user to save password?

  - by Eric

  This is related to the question I asked here: http://stackoverflow.com/questions/2382329/how-can-i-get-browser-to-prompt-to-save-password This is the problem: I CAN'T get my browser to prompt me to save the password for the site I'm developing. (I'm talking about the bar that appears sometimes when you submit a form on Firefox, that says "Remember the password for yoursite.com? Yes / Not now / Never") This is super frustrating because this feature of Firefox (and most other modern browsers, which I hope work in a similar fashion) seems to be a mystery. It's like a magic trick the browser does, where it looks at your code, or what you submit, or something, and if it "looks" like a login form with a username (or email address) field and a password field, it offers to save. Except in this case, where it's not offering my users that option after they use my login form, and it's making me nuts. :-) (I checked my Firefox settings-- I have NOT told the browser "never" for this site. It should be prompting.) My question: exactly what the heuristics are that Firefox (or any other modern browser) uses to know when it should prompt the user to save? This shouldn't be too difficult to answer, since it's right there in the Mozilla source (I don't know where to look or else I'd try to dig it out myself). You'd think there would be a blog post or some other similar developer note from the Mozilla developers about this but I can't find that either. (* Note that if your answer to me has anything to do with cookies, encryption or anything else that is about how I'm storing the user's passwords in the database, you've probably misread my question. :-)

• Solr associations

  - by Tom

  Hi all, The last couple of days we are thinking of using Solr as our search engine of choice. Most of the features we need are out of the box or can be easily configured. There is however one feature that we absolutely need that seems to be well hidden (or missing) in Solr. I'll try to explain with an example. We have lots of documents that are actually businesses: <document> <name>Apache</name> <cat>1</cat> ... </document> <document> <name>McDonalds</name> <cat>2</cat> ... </document> In addition we have another xml file with all the categories and synonyms: <cat id=1> <name>software</name> <synonym>IT<synonym> </cat> <cat id=2> <name>fast food</name> <synonym>restaurant<synonym> </cat> We want to associate both businesses and categories so we can search using the name and/or synonyms of the category. But we do not want to merge these files at indexing time because we should update the categories (adding.remioving synonyms...) without indexing all the businesses again. Is there anything in Solr that does this kind of associations or do we need to develop some specific pieces? All feedback and suggestions are welcome. Thanks in advance, Tom

• Approach for replacing forms authentication in .NET application

  - by Ash Machine

  My question is about an approach, and I am looking for tips or links to help me develop a solution. I have an .NET 4.0 web forms application that works with Forms authentication using the aspnetdb SQL database of users and passwords. A new feature for the application is a new authentication mechanism using single sign on to allow access for thousands of new users. Essentially, when the user logs in through the new single-sign-on method, I will be able to identify them as legitimate users with a role. So I will have something like HttpContext.Current.Session["email_of_authenticated_user"] (their identity) and HttpContext.Current.Session["role_of_authenticated_user"] (their role). Importantly, I don't necessarily want to maintain these users and roles redundantly in the aspnetdb database which will be retired, but I do want to use the session objects above to allow the user to pass through the application as if they were in passing through with forms authentication. I don't think CustomRoleProviders or CustomMemberProviders are helpful since they do not allow for creating session-level users. So my question is how to use the session level user and role that I do have to "mimic" all the forms authentication goodness like enforcing: [System.Security.Permissions.PrincipalPermission(System.Security.Permissions.SecurityAction.Demand, Role = "Student")] or <authorization> <allow users="wilma, barney" /> </authorization> Thanks for any pointers.

• CSS Hover on parent list Item only

  - by Daniel O'Connor

  Hey Everyone, So I have some nested lists (only one level deep) and I'm running into trouble with the CSS :hover feature. I only want the hover to apply to the parent class, but I can't figure that one out. Here's my CSS <style type="text/css" media="screen"> .listblock li img { visibility: hidden; } .listblock li:hover img { visibility: visible; } </style> And here is a sample of one of the lists. <ul> <li>One <a href="#"><img src="img/basket.png" height="16" width="16" alt="Buy" class="buy" onClick="pageTracker._trackEvent('Outbound Links', 'Amazon');"/></a></li> <li>Two <a href="#"><img src="img/basket.png" height="16" width="16" class="buy" /></a> <ul> <li>Uno<a href="#"><img src="img/basket.png" height="16" width="16" class="buy" /></a></li> <li>Dos <a href="#"><img src="img/basket.png" height="16" width="16" class="buy" /></a></li> </ul> </li> <li>Three <a href="#"><img src="img/basket.png" height="16" width="16" alt="Buy" class="buy" onClick="pageTracker._trackEvent('Outbound Links', 'Amazon');"/></a></li> </ul> The problem is that the image in the Uno and Dos list items also hovers. :( Help please! Thanks a lot

• Another IKImageView Question

  - by Brian Postow

  I'm trying to use the select and copy feature of the IKImageView. If all you want to do is have an app with an image, select a portion and copy it to the clipboard, it's easy. You set the copy menu pick to the first responder's copy:(id) method and magically everything works. However, if you want something more complicated, like you want to copy as part of some other operation, I can't seem to find the method to do this. IKImageView doesn't seem to have a copy method, it doesn't seem to have a method that will even tell you the selected rectangle! I have gone through Hillegass' book, so I understand how the clipboard works, just not how to get the portion of the image out of the view... Now, I'm starting to think that I made a mistake in basing my project on IKImageView, but it's what Preview is built on (or so I've read), so I figured it had to be stable... and anyway, now it's too late, I'm too deep in this to start over... So, other than not using IKImageView, any suggestions on how to copy the select region to the clipboard manually?

• php & mySQL: Storing doc, xls, zip, etc. with limited access and archiving

  - by Devner

  Hi all, In my application, I have a provision for users to upload files like doc, xls, zip, etc. I would like to know how to store these files on my website and have only restricted people access it. I may have a group of people and let only these group access those uploaded files. I know that some may try to just copy the link to the document or the file and pass it to another (non-permitted) user and they can download it. So how can I prevent it? How can I check if the request to download the file was made by a legitimate user who has access to the file? The usernames of the group members are stored in the database along with the document name and location in the database so they can access it. But how do I prevent non-permitted users from being able to access that confidential data in all ways? With the above in mind, how do I store these documents? Do I store the documents in a blob column in the Database or just just let user upload to a folder and merely store the path to the file in the database? The security of the documents is of utmost importance. So any procedure that could facilitate this feature would definitely help. I am not into Object Oriented programming so if you have a simpler code that you would like to share with me, I would greatly appreciate it. Also how do I archive documents that are old? Like say there are documents that are 1 year old and I want to conserve my website space by archiving them but still make them available to the user when they need it. How do I go about this? Thank you.

• Basic image resizing in Ruby on Rails

  - by Koning Baard XIV

  I'm creating a little photo sharing site for our home's intranet, and I have an upload feature, which uploads the photo at original size into the database. However, I also want to save the photo in four other sizes: W=1024, W=512, W=256 and W=128, but only the sizes smaller than the original size (e.g. if the original width is 511, only generate 256 and 128). How can I implement this? I already have this code to upload the photo: pic.rb <-- model def image_file=(input_data) self.filename = input_data.original_filename self.content_type = input_data.content_type.chomp self.binary_data = input_data.read # here it should generate the smaller sizes #+and save them to self.binary_data_1024, etc... end new.rb <-- view <h1>New pic</h1> <% form_for(@pic, :html => {:multipart => true}) do |f| %> <%= f.error_messages %> <p> <%= f.label :title %><br /> <%= f.text_field :title %> </p> <p> <%= f.label :description %><br /> <%= f.text_field :description %> </p> <p> <%= f.label :image_file %><br /> <%= f.file_field :image_file %> </p> <p> <%= f.submit 'Create' %> </p> <% end %> <%= link_to 'Back', pics_path %> Thanks

• jquery .submit live click runs more than once

  - by fxuser

  I use the following code to run my form ajax requests but when i use the live selector on a button i can see the ajax response fire 1 time, then if i re-try it 2 times, 3 times, 4 times and so on... I use .live because i also have a feature to add a post and that appears instantly so the user can remove it without refreshing the page... Then this leads to the above problem... using .click could solve this but it's not the ideal solution i'm looking for... jQuery.fn.postAjax = function(success_callback, show_confirm) { this.submit(function(e) { e.preventDefault(); if (show_confirm == true) { if (confirm('Are you sure you want to delete this item? You can\'t undo this.')) { $.post(this.action, $(this).serialize(), $.proxy(success_callback, this)); } } else { $.post(this.action, $(this).serialize(), $.proxy(success_callback, this)); } return false; }) return this; }; $(document).ready(function() { $(".delete_button").live('click', function() { $(this).parent().postAjax(function(data) { if (data.error == true) { } else { } }, true); }); });? EDIT: temporary solution is to change this.submit(function(e) { to this.unbind('submit').bind('submit',function(e) { the problem is how can i protect it for real because people who know how to use Firebug or the same tool on other browsers can easily alter my Javascript code and re-create the problem

• How to access device settings on a Sony Ericsson mobile phone?

  - by TheRHCP

  Edited on April 29th Hello everyone, I recently bought a Sony Ericsson mobile phone which embeds Symbian S60 and I would like to add a missing feature myself. In fact I cannot actually disable Internet connection in an easy way when roaming, which cost me a lot of money last time I moved away ... So I would like to develop a little application that would just replace the actual Internet configuration with a fake configuration to avoid auto-connections. So what I would like to know is how can I access programmatically to my phone settings? I believe that this is possible but I do not really have a clue where to start. I know that Sony Ericsson provides a SDK to run Java applications on its customised JVM but Symbian is also providing a SDK to develop applications for S60 devices in many languages. The real questions is which SDK will provide an API able to access phone settings. This is not well documented so I am asking this question with the hope that someone here already had experience with development for Sony Ericsson/Symbian devices. Thanks. EDIT: It seems that I was totally wrong concerning my phone. This not based on any Symbian OS at all. This is pure Sony Ericsson so the only solution would be to look if Sony Ericsson extended J2ME functionality in their own JVM. I am gonna investigate on this.

• Design suggestions for creating document management structure using hidden shares.

  - by focus.nz

  I need to add some document management functionality into my software. Documents will be grouped by company name and project name. The folders need to be accessed by the application using the id numbers of clients/projects, but also easily browsed by the end user using windows explorer. Clients and Projects will be stored in a database. I am thinking of having the software create the folders using the friendly name and then using a hidden share with the id number for the software to access the files. The folder structure would be something like this --Company 1 (Company-1234$) -- Project 101 (Project-101$) -- Project 102 (Project-102$) -- Project 103 (Project-103$) -- Company 2 (Company-5678$) -- Project 201 (Project-201$) -- Project 202 (Project-202$) -- Project 203 (Project-203$) So in the example above there would be a company called "Company 1" with a ID of "1234". When browsing the folders using windows explorer the user would see \\ServerName\Documents\Company1 and you could also access the same folder from \\ServerName\Documents\Company-1234$ By using the hidden share, if the company name changes or its renamed for some reason it doesn't break the link in the application because its using the hidden shared based on the ID that never changes. Will having hundreds (maybe thousands) or hidden shares on a server provide a huge performance hit? Does any one have any suggestions or alternatives to provide this feature?

• html includes in a JSP using IIS/WebLogic

  - by Striker

  I have my IIS 6 server setup to process server side includes, we're also using the WebLogic ISAPI plugin for IIS. I have a simple html file that I'm trying to include in the JSP using the following include: <!-- #include file="/pleaseWait/pleaseWait.html" --> When I use the above line in a JSP I get an error message saying: "pleaseWait is not defined". From an HTML file on the web server it works fine. The include works in the HTML whether I use file or virtual. I can't use the jsp @ include because that's resolved at build time and the HTML file does not exist in the Java project. It's static content so it's on the IIS server. In the past we've change the extension to .jsp and included the images and static content in the .war file....the problem with that is we now have 10 different versions of this code in our apps and not all of them look or function the same. This is an attempt to standardize and centralize the code for this feature across our apps. Any ideas or suggestions?

• mySQL ORDER BY ASC works, DESC does not...

  - by Ben

  I've "integrated" SMF into Wordpress by querying the forum for a list of the most recent videos from a specific forum board and displaying them on the Wordpress homepage. However when I add the ORDER BY clause, the query (which I tested on other parts of the same page successfully), breaks. To add to the mix, I am using the Auto Embed plugin to allow the videos to be played on the homepage, as well as using a jCarousel feature to rotate them. People were kind enough to help me here last time with the regexp to filter the video urls, I'm hoping for the same luck this time! Here is the entire function (remove the DESC and it works...): function SMF_getRecentVids($limit=10){ global $smf_settingsphp_d; if(file_exists($smf_settingsphp_d)) include($smf_settingsphp_d); include "AutoEmbed-1.4/AutoEmbed.class.php"; $AE = new AutoEmbed(); $connect = new wpdb($db_user,$db_passwd,$db_name,$db_server); $connect->query("SET NAMES 'UTF8'"); $sql = SELECT m.subject, m.ID_MSG, m.body, m.ID_TOPIC, m.ID_BOARD, t.ID_FIRST_MSG FROM {$db_prefix}messages AS m LEFT JOIN {$db_prefix}topics AS t ON (m.ID_TOPIC = t.ID_TOPIC) WHERE (m.ID_BOARD = 8) ORDER BY t.ID_FIRST_MSG DESC"; $vids = $connect->get_results($sql); $c = 0; $content = "imageCarousel_itemList = ["; foreach ($vids as $vid) { if ($c > $limit) continue; //extract video code from body $input = $vid->body; $regexp = "/\b(?:(?:https?|ftp):\/\/|www\.)[-a-z0-9+&@#\/%?=~_|!:,.;]*[-a-z0-9+&@#\/%=~_|]/i"; if(preg_match_all($regexp, $input, $matches)) { $AE->parseUrl($matches[0][0]); $imageURL = $AE->getImageURL(); $AE->setWidth(290); $AE->setHeight(240); $content .= "{url: '".$AE->getEmbedCode()."', title: '".$vid->subject."', caption: '', description: ''},"; } $c++; } $content .= "]"; echo $content; $wpdb = new wpdb(DB_USER, DB_PASSWORD, DB_NAME, DB_HOST); }
