  • JS encodeURIComponent result different from the one created by FORM

    - by Marco Demaio
    I thought values entered in forms are properly encoded by browsers. But this simple test shows it's not true: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html><head> <meta http-equiv="Content-Type" content="text/html; charset=windows-1252"> <title></title> </head><body> <form id="test" action="test_get_vs_encodeuri.html" method="GET" onsubmit="alert(encodeURIComponent(this.one.value));"> <input name="one" type="text" value="Euro-€"> <input type="submit" value="SUBMIT"> </form> </body></html> When hitting submit button: encodeURICompenent encodes input value into "Euro-%E2%82%AC" while browser into the GET query writes only a simple "Euro-%80" Could somone explain? Or is encodeURIComponent doing unnecessary conversions?

  • Image File In Text Editor - What Are The Characters? What's the Process?

    - by TheDarkIn1978
    i'm currently in the process of conceptualizing an art piece for a gallery show next year, so this bizarre question of mine is more than just simple curiosity. if i open up an image file (a .PNG) with Text Edit or Note Pad, the file is presented in textual characters. something like this except: æº"í=™?0Ù:Ã,ÏI8^?K¯pmDHƒÃ?;wÔlD DDF›ä™èÜE[E˜ƒê?¯ƒºäeèçã?'ów+æ1ï‡ê0òHõñ?ò$úîù¥{WÎn}2*Ÿ!y(Ö!%2e9U2µ i4Õ(?=ù(›7}:É?##„G¶VfcVñ[÷D6gvrˆvéZN›=Ù=ó{púp…p?Ók‹oÃvŒÛ»{ùœóüôøW†W–VH\P?P$VTPt^lQ‹_B_S=Q™\Z[Ü)s/{]Œ_û]~¯¿¯Awu˜ùä’JÖ Í*tï[’ÎáÔ=<Æ6?~ZCWSÛpVµ?±ØŒ?nÆ^¨æ??™¡?a¥ë£1µÒÁ#?Gè)G<^mRl™m?jˆj~€"“R–Úª’?u?çO-•m˜â?ìéväˆàˆOä5ùXùûù”]¬]?]›V›œ{X{Óˆ|Ô’Èm{J?4‰Èáæõ}??~Á?óºYáœåüuRFÆ>W|^3Ñ5‰94=,<ú?|1b=2< >ö:?sÃ`¨{úf<f|ÛÖ?ãÊ íâ–âè/_÷O¬}Â?Í›§Ãd’kÃkØ?sSíS? ??øy;-6]ˆ?÷ÌÌÙåËLÈ,l÷uvzNtÆt6Ô6?O ?P?_t_|°N¸]Ÿ{ƒ{è˜3KK> ?x~ò[ñ\ÆXA?x?Ãî?X? ?…°”¸™‘jÂzÕkm~]jObµ·p1°Y‚s?&b”}s?ãËóí-»ñ”÷‰?‡v?ˆ˜WõØ£??æe~;¸n?Ooáa'aÁÎÌ-ª$ª!ª~ ?¨‹CÏpÏO/Á›œ/?80<Ë<§8 can anyone explain what is happening here? are the characters some form translation of pixel data by the text editor? maybe it is completely meaningless / an error? if not, is there a name for this type of data conversion or process?

  • OpenPeak Flash app XMLSocket Security Problem

    - by Kira
    We're trying to create an app for OpenPeak. The Flash app will act as a client to a Java server on another computer on another domain. The Flash app client connects via XMLSocket. The Java Server uses ServerSocket to receive a request and send back a message. In order to trust the server, the Flash client needs a socket master policy file to tell it that the server comes from a trustworthy domain. According to an article on Adobe, when a connection has succeeded, the Flash client automatically requests the cross-domain policy or socket master policy file on port 843. Still, even when we implement it according to the tutorials and recommendations we have read, the Flash client continues to throw the following security error: SecurityErrorEvent type="securityError" bubbles=false cancelable=false eventPhase=2 text="Error #2048" We've tried logging the policy file request during testing to see if there was any call made to port 843. There was not. Interestingly, even without a policy file, the Flash client still manages to send the first data message to the server successfully. It's just when the server tries to send back a reply that the entire thing hangs for about 10 seconds before the security error above is displayed. Any ideas / suggestions?

  • java RMI connection to server

    - by user85116
    I have a very simple rmi client / server application. I don't use the "rmiregistry" application though, I use this to create the server: server = new RemoteServer(); registry = LocateRegistry.createRegistry(PORT); registry.bind("RemoteServer", server); The client part is: registry = LocateRegistry.getRegistry(IPADDRESS, PORT); remote = (IRemoteServer) registry.lookup("RemoteServer"); Here is the fascinating problem: The application works perfectly when both server and client are running in my (private) local network. As soon as I put the server on a public server, the application hangs for a minute, then gives me the following error: java.rmi.ServerException: RemoteException occurred in server thread; nested exception is: java.rmi.ConnectException: Connection refused to host: 192.168.x.y; nested exception is: java.net.ConnectException: Connection timed out: connect at sun.rmi.server.UnicastServerRef.dispatch(Unknown Source) at sun.rmi.transport.Transport$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at sun.rmi.transport.Transport.serviceCall(Unknown Source) at sun.rmi.transport.tcp.TCPTransport.handleMessages(Unknown Source) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run0(Unknown Source ... (the rest is truncated) The key I think is that the client (running on my private network) cannot connect to myself (my address is 192.168.x.y where x.y is some other numbers, but the real error message shows my ip address listed there) If I kill the rmi server on the public internet, then I instantly get a "connection refused to host: a.b.c.d") message, so I know that something at the server end is at least working. Any suggestions? EDIT: just to make this a little more clear: 192.168.x.y is the client address, a.b.c.d is the server address. The stacktrace shows the client cannot connect to the client.

  • Does Team Foundation support cross-app workitem groups?

    - by drachenstern
    We're currently using Visual Source Safe and BugNet and looking to migrate up and away from VSS. I've been pushing for either SVN ( a) we're an ASP.NET shop, b) DCVS is not an option - no matter how much I like Hg ;-) or TFS. Well we finally got a new dev server, so I talked the boss into installing TFS on it (30 day trial). In the meantime, we had started experimenting with FogBugz. We really like FogBugz for about 80% of what we want to do, and the other 20% is probably stuff that we don't know what we want. I'm pushing for TFS because it allows for IDE integrated (mostly) everything. He's pushing for FogBugz because he can group tasks by customer and then project and manage everything from one dashboard. (which means I lose most of my IDE integration - no huge loss I agree) Does TFS support a single dashboard that would span all our solutions (in this case each solution is a full app that we sell to a vertical market client) and let us assign workitems to each solution-spanning-group? So for instance I think we envision something like this: PROJECT1 - Bugtracker and workitems PROJECT2 - Bugtracker and workitems PROJECT3 - Bugtracker and workitems CUSTOMER1 - Deployment schedules, required features, specific notes (Uses PROJECT1, PROJECT2) CUSTOMER2 - Deployment schedules, required features, specific notes (Uses PROJECT2, PROJECT3) CUSTOMER3 - Deployment schedules, required features, specific notes (Uses PROJECT1, PROJECT3) Hopefully that makes sense. naturally it's more complicated than this but I think I've given the details enough to paint a picture. I offered the option of creating dummy projects per customer but he doesn't like that and it doesn't really give us the single dashboard view that we're hoping to end up with (and that FogBugz as we've sorta implmented things does do now). Has anyone got a good suggestion on a management app that would accomplish what both of us want?

  • Multithreaded IOCP Client Issue

    - by Carl
    I am writing a multithreaded client that uses an IO Completion Port. I create and connect the socket that has the WSA_FLAG_OVERLAPPED attribute set. if ((m_socket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP)) == INVALID_SOCKET) { throw std::exception("Failed to create socket."); } if (WSAConnectByName(m_socket, L"server.com", L"80", &localAddressLength, reinterpret_cast<sockaddr*>(&localAddress), &remoteAddressLength, &remoteAddress, NULL, NULL) == FALSE) { throw std::exception("Failed to connect."); } I associate the IO Completion Port with the socket. if ((m_hIOCP = CreateIoCompletionPort(reinterpret_cast<HANDLE>(m_socket), m_hIOCP, NULL, 8)) == NULL) { throw std::exception("Failed to create IOCP object."); } All appears to go well until I try to send some data over the socket. SocketData* socketData = new SocketData; socketData->hEvent = 0; DWORD bytesSent = 0; if (WSASend(m_socket, socketData->SetBuffer(socketData->GenerateLoginRequestHeader()), 1, &bytesSent, NULL, reinterpret_cast<OVERLAPPED*>(socketData), NULL) == SOCKET_ERROR && WSAGetLastError() != WSA_IO_PENDING) { throw std::exception("Failed to send data."); } Instead of returning SOCKET_ERROR with the last error set to WSA_IO_PENDING, WSASend returns immediately. I need the IO to pend and for it's completion to be handled in my thread function which is also my worker thread. unsigned int __stdcall MyClass::WorkerThread(void* lpThis) { } I've done this before but I don't know what is going wrong in this case, I'd greatly appreciate any efforts in helping me fix this problem.

  • Generate colors between red and green for a power meter?

    - by Simucal
    I'm writing a java game and I want to implement a power meter for how hard you are going to shoot something. I need to write a function that takes a int between 0 - 100, and based on how high that number is, it will return a color between Green (0 on the power scale) and Red (100 on the power scale). Similar to how volume controls work: What operation do I need to do on the Red, Green, and Blue components of a color to generate the colors between Green and Red? So, I could run say, getColor(80) and it will return an orangish color (its values in R, G, B) or getColor(10) which will return a more Green/Yellow rgb value. I know I need to increase components of the R, G, B values for a new color, but I don't know specifically what goes up or down as the colors shift from Green-Red. Progress: I ended up using HSV/HSB color space because I liked the gradiant better (no dark browns in the middle). The function I used was (in java): public Color getColor(double power) { double H = power * 0.4; // Hue (note 0.4 = Green, see huge chart below) double S = 0.9; // Saturation double B = 0.9; // Brightness return Color.getHSBColor((float)H, (float)S, (float)B); } Where "power" is a number between 0.0 and 1.0. 0.0 will return a bright red, 1.0 will return a bright green. Java Hue Chart: Thanks everyone for helping me with this!

  • Java Stop Server Thread

    - by ikurtz
    the following code is server code in my app: private int serverPort; private Thread serverThread = null; public void networkListen(int port){ serverPort = port; if (serverThread == null){ Runnable serverRunnable = new ServerRunnable(); serverThread = new Thread(serverRunnable); serverThread.start(); } else { } } public class ServerRunnable implements Runnable { public void run(){ try { //networkConnected = false; //netMessage = "Listening for Connection"; //networkMessage = new NetworkMessage(networkConnected, netMessage); //setChanged(); //notifyObservers(networkMessage); ServerSocket serverSocket = new ServerSocket(serverPort, backlog); commSocket = serverSocket.accept(); serverSocket.close(); serverSocket = null; //networkConnected = true; //netMessage = "Connected: " + commSocket.getInetAddress().getHostAddress() + ":" + //commSocket.getPort(); //networkMessage = new NetworkMessage(networkConnected, netMessage); //setChanged(); //notifyObservers(networkMessage); } catch (IOException e){ //networkConnected = false; //netMessage = "ServerRunnable Network Unavailable"; //System.out.println(e.getMessage()); //networkMessage = new NetworkMessage(networkConnected, netMessage); //setChanged(); //notifyObservers(networkMessage); } } } The code sort of works i.e. if im attempting a straight connection both ends communicate and update. The issue is while im listening for a connection if i want to quit listening then the server thread continues running and causes problems. i know i should not use .stop() on a thread so i was wondering what the solution would look like with this in mind? EDIT: commented out unneeded code.

  • WordPerfect programmers refusing to use anything but assembler

    - by Totophil
    There is a version (popularised by Joel Spolsky) attributing the demise of WordPerfect to a refusal of its programmers to use anything but assembler that led to delay of the first WPwin release and as result eventually to losing the all important battle with Microsoft. There are a few references to programming work being done using assembler in the autobiographical book "Almost Perfect" by W. E. Pete Peterson who used to have a major influence at running the corporation. But these references go back to early 80's when WordPerfect was trying to gain a significant market share by defeating WordStar and not early nineties when the battle with MS took place. I am looking for a second independent source to confirm the assumption. Maybe someone who worked for WordPerfect Corporation at a time, who was close to the company, or had a chance to see the source could clarify the issue. Your help is much appreciated, thanks! Please note that this question is not about any other theories or reasons behind WordPerfect demise. I really just need to clarify whether they used assembler as a primary language for WPwin and (as a bonus really) whether there were discussions held within the corporation about assembler being the right choice. Concisely: Did WPCorp use assembler as a primary language for WPwin? Were discussions held at a time amongst WP Corp staff about assembler being the right choice (was it management or programmers decision)?

  • Resolving NameErrors -- Getting NameError on RAILS_END in rails_end.rb When using desert plugin and

    - by dr
    What's an effective approach to debug NameErrors in Rails? I'm trying to use the desert plugin (0.5.0) and the edge version of Community_Engine. I've started from scratch and gone through the installation instructions. When I attempt to start my server, I get this error: "Constant RAILS_END from rails_end.rb not found (NameError)". Problem is I cannot find rails_end.rb, nor can I find a google reference to this file or error. I've verified that the required gems are installed and current. I've dug around google and desert, but haven't found any reference to this constant. Any ideas?

  • Is there an event that raises after a View/PartialView executes in ASP.NET MVC 2 RC2?

    - by sabanito
    I have the following problem: We have an ASP.NET MVC 2 RC 2 application that programmatically impersonates an AD Account that the user specifies at logon. This account is used to access the DB. At first we had the impersonating code in the begin_request and we were undoing the impersonation at the end_request, but when we tried to use IIS 7.5 in integrated mode, we learned that it's not possible to impersonate in the Global.asax so we tried different things. We have succesfully moved our code from the BeginRequest to the ActionExecuting event and the EndRequest to the ResultExecuted, and now, about 80% of our code works. We've just discovered that since we're passing the Entity Framework objects as models for our views, there's this remaining 20% that won't work because some Navigation Properties are not loaded when the view begins it's execution, so we're getting connection exceptions from Sql Server. Is there any event or method that executes AFTER the view, so we can undo the impersonation in it? We thought ResultExecuted will do just that, but it doesn't. We've been told that passing the plain Entities into the view as models is not a good idea, but we have A LOT of views that may have this problem and there's not automated way to know it. If some of you could explain why it's not a good idea, maybe we can convince the team to fix it!

  • Visual Studio 2008: Can't connect to known good TFS 2010 beta 2

    - by p.campbell
    A freshly installed TFS 2010 Beta 2 is at http://serverX:8080/tfs. A Windows 7 developer machine with VS 2008 Pro SP1 and the VS2008 Team Explorer (no SP). The TFS 2008 Service Pack 1 didn't work for me - "None of the products that are addressed by this software update are installed on this computer." The developer machine is able to browse the TFS site at the above URL. The Issue is around trying to add the TFS server into the Team Explorer window in Visual Studio 2008. Here's a screenshot showing the error: unable to connect to this Team Foundation Server. Possible reasons for failure include: The Team Foundation Server name, port number or protocol is incorrect. The Team Foundation Server is offline. Password is expired or incorrect. The TFS server is up and running properly. Firewall ports are open, and is accessible via the browser on the dev machine!! larger image Question: how can you connect from VS 2008 Pro to a TFS 2010 Beta 2 server? Resolution Here's how I solved this problem: installed VS 2008 Team Explorer as above. re-install VS 2008 Service Pack 1 when adding a TFS server to Team Explorer, you MUST specify the URL as such: http://[tfsserver]:[port]/[vdir]/[projectCollection] in my case above, it was http://serverX:8080/tfs/AppDev-TestProject you cannot simply add the TFS server name and have VS look for all Project Collections on the server. TFS 2010 has a new URL (by default) and VS 2008 doesn't recognize how to gather that list.

  • WCF Discovery finds endpoint but host is "localhost"

It works fine on my machine, but then I wanted to run the service on a different machine.

  • Sending email through a Google Apps account is working locally, but not on my web server...

    - by Janis Baldwin
    Related: Send Email via C# through Google Apps account My question is the same so I implemented Koistya's solution as follows. The heartbreak is that it works beautifully on my dev laptop but when ported to web server it times out with no explanation. My SMTP config is in my web.config file. I made mods based on Koistya's answer: <mailSettings> **Changed** <smtp from="[email protected]"> <network host="smtp.gmail.com" password="[password]" port="587" userName="[email protected]"/> </smtp> **Original** <!--<smtp from="[email protected]"> <network host="mail.domain.com" password="[password]" port="25" userName="[email protected]"/> </smtp>--> </mailSettings> My .Net C# code (before & after removed): SmtpClient mSmtpClient = new SmtpClient(); mSmtpClient.EnableSsl = true; mSmtpClient.Send(message); As I said this works great on my dev environment but not on web. Can anyone help? Thanks.

  • How to improve performance of non-scalar aggregations on denormalized tables

    - by The Lazy DBA
    Suppose we have a denormalized table with about 80 columns, and grows at the rate of ~10 million rows (about 5GB) per month. We currently have 3 1/2 years of data (~400M rows, ~200GB). We create a clustered index to best suit retrieving data from the table on the following columns that serve as our primary key... [FileDate] ASC, [Region] ASC, [KeyValue1] ASC, [KeyValue2] ASC ... because when we query the table, we always have the entire primary key. So these queries always result in clustered index seeks and are therefore very fast, and fragmentation is kept to a minimum. However, we do have a situation where we want to get the most recent FileDate for every Region, typically for reports, i.e. SELECT [Region] , MAX([FileDate]) AS [FileDate] FROM HugeTable GROUP BY [Region] The "best" solution I can come up to this is to create a non-clustered index on Region. Although it means an additional insert on the table during loads, the hit isn't minimal (we load 4 times per day, so fewer than 100,000 additional index inserts per load). Since the table is also partitioned by FileDate, results to our query come back quickly enough (200ms or so), and that result set is cached until the next load. However I'm guessing that someone with more data warehousing experience might have a solution that's more optimal, as this, for some reason, doesn't "feel right".

  • Automatic web form testing/filling

    - by Polatrite
    I recently became lead on getting an inordinate amount of testing done in a very short period of time. We have many different web forms, using custom (Telerik) controls that need to be tested for proper data validation and sensible handling of the data. Some of the forms are several pages long with 30-80 different controls for data entry. I am looking for a software solution (that is free) that would allow me to automate the process of filling in these forms by designing a script, or using a UI. The other requirement is that I can't use any browsers but IE6 (terrible, I know). I have previously used AutoHotkey to great success for automatic Windows form testing, since Autohotkey's API allows you to directly reference controls on the Windows form. However Autohotkey does not have similar support for web forms (everything is just one big "InternetExplorer" control). While I would prefer that I could script some variance in the data to help serialize each test, it's not necessary, as I could go back through and manually edit a field or two (plus "break" whatever control I'm currently testing) to serialize each test. If you've ever seen Spawner: http://forge.mysql.com/projects/project.php?id=214 It's almost exactly the sort of thing I'm looking for (Spawner generates dummy SQL data, as opposed to dummy webform data) - but I won't be picky, I've got a really short deadline to meet and had this thrust in my lap just today. ;) Edit1: One of the challenges of just using Autohotkey to simulate keyboard input (tabbing through controls) is that some controls don't currently have tab index (bug), and some controls cause a page reload after modification, resulting in inconsistent control focus (tabbing screwed up). Our application makes heavy use of page reloads to populate fields (select a location, it auto-populates a city, for example).

  • Getting nice sound from Java

    - by Peter Lang
    I managed to play midi files using Java, but it produces some distracting noise. I figured out that this is caused by the poor quality soundbank file shipped with Java 6 SDK/JRE. How can I improve that quality? Here is what I have so far: MidiNote example using a Receiver works fine (sounds the same as when playing midi files with other players), so it does not seem to use the Soundbank shipped with Java but the fallback mechanism that uses a hardware MIDI port. Using SimpleMidiPlayer example to play a Midi file works, but the quality is poor. When I delete lib/audio/soundbank.gm, the quality is not bad any more, so the fallback is used again. When I put soundbank-deluxe.gm into the same directory, it is used and produces much better sound. Messing with the clients soundbank file as described in the official Installation Instructions certainly isn't an option, so I tried to put the new soundbank-file into the jar-file and load it: Soundbank soundbank = MidiSystem.getSoundbank( getClass().getResourceAsStream("soundbank-deluxe.gm")); if(synthesizer.isSoundbankSupported(soundbank)) { System.out.println(synthesizer.loadAllInstruments(soundbank)); } This prints true, but the sound remains unchanged. What am I doing wrong loading the soundbank file? Can I force the hardware MIDI port to be used instead of the standard soundbank file?

  • iPhone OS: Strategies for high density image work

    - by Jasconius
    I have a project that is coming around the bend this summer that is going to involve, potentially, an extremely high volume of image data for display. We are talking hundreds of 640x480-ish images in a given application session (scaled to a smaller resolution when displayed), and handfuls of very large (1280x1024 or higher) images at a time. I've already done some preliminary work and I've found that the typical 640x480ish image is just a shade under 1MB in memory when placed into a UIImageView and displayed... but the very large images can be a whopping 5+ MB's in some cases. This project is actually be targeted at the iPad, which, in my Instruments tests seems to cap out at about 80-100MB's of addressable physical memory. Details aside, I need to start thinking of how to move huge volumes of image data between virtual and physical memory while preserving the fluidity and responsiveness of the application, which will be high visibility. I'm probably on the higher ends of intermediate at Objective-C... so I am looking for some solid articles and advice on the following: 1) Responsible management of UIImage and UIImageView in the name of conserving physical RAM 2) Merits of using CGImage over UIImage, particularly for the huge images, and if there will be any performance gain 3) Anything dealing with memory paging particularly as it pertains to images I will epilogue by saying that the numbers I have above maybe off by about 10 or 15%. Images may or may not end up being bundled into the actual app itself as opposed to being loaded in from an external server.

  • Apache mod_rewrite RewriteCond to by-pass static resources not working

    - by d11wtq
    I can't for the life of me fathom out why this RewriteCond is causing every request to be sent to my FastCGI application when it should in fact be letting Apache serve up the static resources. I've added a hello.txt file to my DocumentRoot to demonstrate. The text file: ls /Sites/CioccolataTest.webapp/Contents/Resources/static hello.txt` The VirtualHost and it's rewrite rules: AppClass /Sites/CioccolataTest.webapp/Contents/MacOS/CioccolataTest -port 5065 FastCgiExternalServer /Sites/CioccolataTest.webapp/Contents/MacOS/CioccolataTest.fcgi -host 127.0.0.1:5065 <VirtualHost *:80> ServerName cioccolata-test.webdev DocumentRoot /Sites/CioccolataTest.webapp/Contents/Resources/static RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^/(.*)$ /Sites/CioccolataTest.webapp/Contents/MacOS/CioccolataTest.fcgi/$1 [QSA,L] </VirtualHost> Even with the -f, Apache is directing requests for this text file (i.e. access http://cioccolata-test.webdev/hello.txt returns my app, not the text file). As a proof of concept I changed the RewriteCond to: RewriteCond %{REQUEST_URI} !^/hello.txt That made it serve the text file correctly and allowed every other request to hit the FastCGI application. Why doesn't my original version work? I need to tell apache to serve every file in the DocumentRoot as a static resource, but if the file doesn't exist it should rewrite the request to my FastCGI application. NOTE: The running FastCGI application is at /Sites/CioccolataTest.webapp/Contents/MacOS/CioccolataTest (without the .fcgi prefix)... the .fcgi prefix is only being used to tell the fastcgi module to direct the request to the app.

  • How to I display results of phpcs in VIM?

    - by Matt
    I am presently trying to use PHP Codesniffer (PEAR) in vim for PHP Files. I have found 2 sites that give code to add into the $HOME/.vim/plugin/phpcs.vim file. I have added the code and I "think" it is working, but I cannot see the results, I only see one line at the very bottom of vim that says (1 of 32) but I cannot see any of the 32 errors. Here is my .vimrc file " Backup Options -> Some People may not want this... it generates extra files set backup " Enable Backups set backupext=.bak " Add .bak extention to modified files set patchmode=.orig " Copy original file to with .orig extention Before saving. " Set Tabs and spacing for PHP as recomended by PEAR and Zend set expandtab set shiftwidth=4 set softtabstop=4 set tabstop=4 " Set Auto-indent options set cindent set smartindent set autoindent " Show lines that exceed 80 characters match ErrorMsg '\%80v.\+' " Set Colors set background=dark " Show a status bar set ruler set laststatus=2 " Set Search options highlight, and wrap search set hls is set wrapscan " File Type detection filetype on filetype plugin on " Enable Spell Checking set spell " Enable Code Folding set foldenable set foldmethod=syntax " PHP Specific options let php_sql_query=1 " Highlight sql in php strings let php_htmlInStrings=1 " Highlight HTML in php strings let php_noShortTags=1 " Disable PHP Short Tags let php_folding=1 " Enable Ability to FOLD html Code I have tried 2 different versions of phpcs.vim, and I get the same results for both: Version 1 (found at: VIM an a PHP IDE) function! RunPhpcs() let l:filename=@% let l:phpcs_output=system('phpcs --report=csv --standard=YMC '.l:filename) " echo l:phpcs_output let l:phpcs_list=split(l:phpcs_output, "\n") unlet l:phpcs_list[0] cexpr l:phpcs_list cwindow endfunction set errorformat+=\"%f\"\\,%l\\,%c\\,%t%*[a-zA-Z]\\,\"%m\" command! Phpcs execute RunPhpcs() Version 2: (found at Integrated PHP Codesniffer in VIM ) function! RunPhpcs() let l:filename=@% let l:phpcs_output=system('phpcs --report=csv --standard=YMC '.l:filename) let l:phpcs_list=split(l:phpcs_output, "\n") unlet l:phpcs_list[0] cexpr l:phpcs_list cwindow endfunction set errorformat+="%f"\\,%l\\,%c\\,%t%*[a-zA-Z]\\,"%m" command! Phpcs execute RunPhpcs() Both of these produce identical results. phpcs is installed on my system, and I am able to generate results outside of vim. Any help would be appreciated I am just learning more about vim...

  • Several xml errors using Facebook JS SDK with xhtml strict

    - by Landitus
    I'm trying to set up some like buttons to a project. These buttons live inside a jquery slideshow with Aino's Galleria and let you "Like" each different slide. I'm using an xHTML strict document and while in Firefox (and Firebug) everything seems ok, but in webkit inspector I get this: XML self-closing tag syntax used on <fb:like>. The tag will not be closed. [The HTML that caused this error was generated by a script.] XML self-closing tag syntax used on <fb:like>. The tag will not be closed. I get one of these every slide, so there are 28 errors. Looking into it, found some seem to enclose the fb:like into something like this: <script type="text/javascript"> //<![CDATA[ document.write('<fb:like href="<?php echo "http://www.site/image-".$image_id ;?>" width="260" height="80" show_faces="false" />'); //]]> </script> The above, still works in Firefox, but not in Safari. The inspector says: 26 XFBML tags failed to render in 30000ms. Moreover, for the Facebook like buttons to work with the Galleria Jquery plugin, I have a custom function that reloads only the facebook like button concerning the actual slide which appears briefly upon loading the slide: [...] extend: function(options) { // listen to when an image is shown this.bind(Galleria.IMAGE, function(e) { number = e.index + 1; tag = $('.galleria-info-description .info-box-'+number).find('.btn_fb'); $(tag).each(function() { FB.XFBML.parse( this ); }); }); } This thing is getting more complex and really don't know who is causing the problem! Hope somebody can help or ask the right questions!

How can I hide the column permanently?
