  • how to load local html file into uiwebview iphone

    - by madcoderz
    I'm trying to load a html file into my UIWebView but it won't work. Here's the stage: I have a folder called html_files in my project. Then I created a webView in interface builder and assigned an outlet to it in the viewController. This is the code I'm using to append the html file: -(void)viewDidLoad { NSString *htmlFile = [[NSBundle mainBundle] pathForResource:@"sample" ofType:@"html" inDirectory:@"html_files"]; NSData *htmlData = [NSData dataWithContentsOfFile:htmlFile]; [webView loadData:htmlData MIMEType:@"text/html" textEncodingName:@"UTF-8" baseURL:[NSURL URLWithString:@""]]; [super viewDidLoad]; } That won't work and the UIWebView is blank. I'd appreciate some help.

  • AdMob won't load programmatically

    - by scottbot95
    I'm need to include ads into my app and I have a settings option to disable ads. so I need to load the ad in code. I copied the code from google to handle that and when I set ads:loadAdOnCreate to true, it works just fine. But if I set it to false and add the two lines AdView adView = (AdView)this.findViewById(R.id.ad); adView.loadAd(new AdRequest()); The ads stop displaying. If I look at log cat, it shows that it is receiving an ad and trying to display it. However it won't actually display on screen. Help?

  • on page load clone first image from collection of photos

    - by user313378
    On my page I'm getting collection of photos, and I store them as thumbs below showImage div which needs to be refreshed with cloned image onclick. Basically everything is ok except I need to populate this showImage div onpage load with first image, and then to use this onclick clone which already works. <a href="/Property/GetImage/someIntId"> <img id="someIntId" class="details" width="100" height="100" src="/Property/GetImage/7" alt=""> </a> function onPopUp() { $(".details").click(function (event) { //clone the clicked image var clone = $(this).clone(); clone.height("250px").width("280px"); //place it in the placeholder $('div#showImage').html(clone); }); }

  • jQuery: Load body of page into variable

    - by Nathan G.
    I'm using jQuery to load the result of a PHP script into a variable. The script is passed something that the user typed with a GET request. I want to take just what the script spit out into its <body> tag. Here's what I've tried: JS: function loader() { var typed = $('#i').val(); //get what user typed in $.get("script.php", {i: typed}, function(loaded) {dataloaded = loaded;}); alert($(dataloaded).find('body')) } But it just displays [Objec object]. How can I get a useful value that is just the contents of the body of a loaded page? I know the PHP works, I just need the JS. The script echos something like 1!!2 (two numbers separated by two exclamation points). Thanks!

  • Load custom class properly

    - by LinusAn
    I have a custom class which I want to "load" inside the firstViewController and then access it from other classes by segues. My Problem is, I can't even access and change the instance variable inside the firstViewController. Somehow I'm "loading" it wrong. Here is the code I used until now: inside viewController.h @property (strong, nonatomic) myClass *newClass; inside viewController.m @synthesize newClass; I then try to access it by: self.newClass.string = @"myString"; if(newClass.string == @"myString"){ NSLog(@"didn't work"); } Well, I get "didn't work". Why is that? When I write myClass *newClass = [myClass new]; It does work. But the class and its properties gets overwritten every time the ViewController loads again. What would you recommend? Thank you very much.

  • JQuery QuickSearch: Searching on load if the input isn't blank

    - by ckm-88
    I have used the jquery quicksearch plugin and it works fine, except for one problem. I would like the quicksearch to run when the page is loaded. I have created a second quicksearch function (which is called when the page is loaded) and changed the bind to something else, but it won't work on "load" or "ready". If I change the bind to "focus" and put the focus onto the textfield it works, but only in IE. The reason I want to do this is because there is a "view" link where the user leaves the page. When they come back, I would like the search results to be as they left them.

  • call .js file after ajax load

    - by asovgir
    I am trying to apply a .js file to a page I loaded via ajax (since ajax automatically strips the content of all the javascript). var url; var textUrl = 'local/file.js'; $('a').click(function() { url = $(this).attr('href'); $('.secondaryDiv').load(url, function() { $.getScript(textUrl, function(data, textStatus, jqxhr) { console.log(data); //data returned from getScript console.log(textStatus); //return "success" console.log(jqxhr.status); //200 }); }); return false; }); Am I approaching this the right way? I tried everything I could think of and I can't get it to work

  • DOMDocument::load in PHP 5

    - by Abs
    Hello all, I open a 10MB+ XML file several times in my script in different functions: $dom = DOMDocument::load( $file ) or die('couldnt open'); 1) Is the above the old style of loading a document? I am using PHP 5. Oppening it statically? 2) Do I need to close the loading of the XML file, if possible? I suspect its causing memory problems because I loop through the nodes of the XML file several thousand times and sometimes my script just ends abruptly. Thanks all for any help

    - by QuBaR
    I have a html table with a column per row with this html code inside the tags: <a onclick="modalDialog(this); return false;" href="javascript:void(0)">17795</a> <div style="display: none;" class="MessageDataDiv"> some text to show up in my jquery modal window when function modaldialog is clicked. </div> And the jquery function that is called when onclick is fired within the a href link function modalDialog(event) { $('a.message').click(function () { var div = new $(this).closest("td").find(".MessageDataDiv").clone(); div.show().dialog(); event.preventDefault(); }); } Can anyone help me with some advice how to write the jquery function more correct so the function only fires one time when the linked is clicked. I need to have the jquery function modalDialog as a separate function because the html table use ajax partial rendering... The problem is when i click the a href link first time nothing happens, second click on the links gives med two modal dialog and third click gives me three modal dialog and so on...

  • Weblogic EJB calls start to fail under moderate load with OptionalDataException

    - by MarkoU
    Our system setup consists of two Weblogic 10.3 servers: one hosts the presentation layer and the other hosts the EJBs. The system runs fine under moderate load for some time (one to several days) after which EJB method calls from the presentation server to the EJB server start to fail with the following error: java.rmi.RemoteException: java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is: java.io.OptionalDataException Stack trace: java.io.OptionalDataException at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1349) at java.io.ObjectInputStream.readObject(ObjectInputStream.java:351) at weblogic.utils.io.ChunkedObjectInputStream.readObject(ChunkedObjectInputStream.java:197) at weblogic.rjvm.MsgAbbrevInputStream.readObject(MsgAbbrevInputStream.java:564) at weblogic.utils.io.ChunkedObjectInputStream.readObject(ChunkedObjectInputStream.java:193) at weblogic.jndi.internal.RootNamingNode_WLSkel.invoke(Unknown Source) at weblogic.rmi.internal.BasicServerRef.invoke(BasicServerRef.java:589) at weblogic.rmi.cluster.ClusterableServerRef.invoke(ClusterableServerRef.java:230) at weblogic.rmi.internal.BasicServerRef$1.run(BasicServerRef.java:477) at weblogic.security.acl.internal.AuthenticatedSubject.doAs(AuthenticatedSubject.java:363) at weblogic.security.service.SecurityManager.runAs(Unknown Source) at weblogic.rmi.internal.BasicServerRef.handleRequest(BasicServerRef.java:473) at weblogic.rmi.internal.wls.WLSExecuteRequest.run(WLSExecuteRequest.java:118) Once the first OptionalDataException is encountered all subsequent calls fail with the same result. Some sources suggest that this might be related to cluster multicast port being misconfigured. However, these servers do not belong to a cluster. Booting the EJB server always temporarily resolves the issue, but the issue seems to occur again after some time. Any ideas?

  • psqlODBC won't load after installing MS SQL ODBC driver on RHEL 6

    - by Kapil Vyas
    I had the PostgreSQL drivers working on my RHEL 6. But after I installed Microsoft® SQL Server® ODBC Driver 1.0 for Linux I can no longer connect to PosgreSQL data sources. I can connect to SQL Server data sources fine. When I had this same issue a week ago I uninstalled MS SQL Server ODBC driver from Linux and it fixed the issue. I had to copy the psqlodbcw.so files from another machine to replenish the files. I don't want to do the same this time. I want both drivers to work on Linux. This time around the setup files got deleted: /usr/lib64/libodbcpsqlS.so. Replenishing it did not fix the issue. I kept getting the following error in spite of the file being present with rwx permisions: [root@localhost lib64]# isql -v STUDENT dsname pwd12345 [01000][unixODBC][Driver Manager]Can't open lib '/usr/lib64/psqlodbc.so' : file not found [ISQL]ERROR: Could not SQLConnect [root@localhost lib64]# Here is a printout of the file permissions: [root@localhost lib64]# ls -al p*.so lrwxrwxrwx. 1 root root 12 Dec 7 09:15 psqlodbc.so -> psqlodbcw.so -rwxr-xr-x. 1 root root 519496 Dec 7 09:35 psqlodbcw.so and my odbcinst.ini file looks as follows: [PostgreSQL] Description=ODBC for PostgreSQL Driver=/usr/lib/psqlodbc.so Driver64=/usr/lib64/psqlodbc.so Setup=/usr/lib/libodbcpsqlS.so Setup64=/usr/lib64/libodbcpsqlS.so FileUsage=1 UsageCount=4 I also referred to this link: http://mailman.unixodbc.org/pipermail/unixodbc-support/2010-September.txt

  • where is the best palce to count the lazy load property using JPA

    - by Ke
    Let's say we have a "Question" and "Answer" entity, @Entity public class Question extends IdEntity { @Lob private String content; @Transient private int answerTotal; @OneToMany(fetch = FetchType.LAZY) private List<Answer> answers = new ArrayList<Answer>(); ...... I need to tell how many answers for the question every time Question is queryed. So I need to do count: String count = "select count(o) from Answer o WHERE o.question=:q"; My question is, where is the best place to do the count? (Because I did a lot of query about Question entity, by date, by tag, by category, by asker, etc. It is obviously not a good solution to add count operation in each query. My first attempt is to implement a @PostLoad listener, so every time Question entity is loaded, I do count. However, EntityManager cannot be injected in listener. So this way does not work. Any hint?

  • How to lazy load a data structure (python)

    - by Anton Geraschenko
    I have some way of building a data structure (out of some file contents, say): def loadfile(FILE): return # some data structure created from the contents of FILE So I can do things like puppies = loadfile("puppies.csv") # wait for loadfile to work kitties = loadfile("kitties.csv") # wait some more print len(puppies) print puppies[32] In the above example, I wasted a bunch of time actually reading kitties.csv and creating a data structure that I never used. I'd like to avoid that waste without constantly checking if not kitties whenever I want to do something. I'd like to be able to do puppies = lazyload("puppies.csv") # instant kitties = lazyload("kitties.csv") # instant print len(puppies) # wait for loadfile print puppies[32] So if I don't ever try to do anything with kitties, loadfile("kitties.csv") never gets called. Is there some standard way to do this? After playing around with it for a bit, I produced the following solution, which appears to work correctly and is quite brief. Are there some alternatives? Are there drawbacks to using this approach that I should keep in mind? class lazyload: def __init__(self,FILE): self.FILE = FILE self.F = None def __getattr__(self,name): if not self.F: print "loading %s" % self.FILE self.F = loadfile(self.FILE) return object.__getattribute__(self.F, name) What might be even better is if something like this worked: class lazyload: def __init__(self,FILE): self.FILE = FILE def __getattr__(self,name): self = loadfile(self.FILE) # this never gets called again # since self is no longer a # lazyload instance return object.__getattribute__(self, name) But this doesn't work because self is local. It actually ends up calling loadfile every time you do anything.

  • HAProxy reqrep remove URI on backend request

    - by Jim
    real quick question regarding HAProxy reqrep. I am trying to rewrite/replace the request that gets sent to the backend. I have the following example domain and URIs http://domain/web1 http://domain/web2 I want web1 to go to backend webfarm1, and web2 to go to webfarm2. Currently this does happen. However I want to strip off the web1 or web2 URI when the request is sent to the backend. Here is my haproxy.cfg frontend webVIP_80 mode http bind :80 #acl routing to backend acl web1_path path_beg /web1 acl web2_path path_beg /web2 #which backend use_backend webfarm1 if web1_path use_backend webfarm2 if web2_path default_backend webfarm1 backend webfarm1 mode http reqrep ^([^\ ]*)\ /web1/(.*) \1\ /\2 balance roundrobin option httpchk HEAD /index HTTP/1.1\r\nHost:\ example.com server webtest1 10.0.0.10:80 weight 5 check slowstart 5000ms server webtest2 10.0.0.20:80 weight 5 check slowstart 5000ms backend webfarm2 mode http reqrep ^([^\ ]*)\ /web2/(.*) \1\ /\2 balance roundrobin option httpchk HEAD /index HTTP/1.1\r\nHost:\ example.com server webtest1-farm2 10.0.0.110:80 weight 5 check slowstart 5000ms server webtest2-farm2 10.0.0.120:80 weight 5 check slowstart 5000ms If I go to http://domain/web1 or http://domain/web2 I see it in the error logs that the request on a server in each backend that the requst is for the resource /web1 or /web2 respectively. Therefore I believe there to be something wrong with my regular expression, even though I copied and pasted it from the Documentation. http://code.google.com/p/haproxy-docs/wiki/reqrep Summary: I'm trying to route traffic based on URI, however I want to strip the URI on the backend side. Go to http://domain/web1 -- backend request of / to webfarm1 Thank you! -Jim

  • Extract Key and Certificate from Kemp Loadmaster?

    - by Matt Simmons
    I'm trying very hard to get away from a set of Kemp Loadmasters that I bought years ago to provide HA access to our website. Part of that process is going to be putting the key and certificate in the new solution (HAproxy with nginx doing SSL). Unfortunately, I've come up against a problem... The Kemp has built-in certificate management, and it generates CSR's at the touch of a button. It also supported importing of signed certificates, however it does not, so far as I can tell, allow any kind of export of the key itself. There is a "backup key and certificates" ability, however here's the text from the manual: LoadMaster supports exporting of ALL certificate information. This includes private key, host and intermediate certificates. The export file is designed to be used for import into another LoadMaster and is encrypted. Export and import can be completed using the WUI at Certificates -> Backup/Restore Certs. Please make sure to note the pass phrase used to create the export, it will be required to complete the import. You can selectively resort only Virtual Service certificates including private keys, intermediate certificates or both. Well, that is great, but as for actually DEALING with the certs, I'm apparently out of luck. Of course, I'm not going to give up that easily. I ran "file" on the saved cert bundle and got this: $ file client1.certs.backup client1.certs.backup: gzip compressed data, from Unix Well, awesome, I thought. Maybe it's just a .tar.gz, so I unzipped it, and that went fine, but my attempts to untar it didn't work, and running "file" on it now just gives this: $ file client1.certs.backup client1.certs.backup: data So that's where I'm stuck. Anyone have experience with these?

  • GlusterFS vs Ceph, which is better for production use for the moment?

    - by Mickey Shine
    I am evaluating GlusterFS and Ceph, seems Gluster is FUSE based which means it may be not as fast as Ceph. But looks like Gluster got a very friendly control panel and is ease to use. Ceph was merged into linux kernel a few days ago and this indicates that it has much more potential energy and may be a good choice in the future. I am wondering which(even out of the two?) is a better choice for production use? It would be nice if you could share your practical experiences

  • Campus Network Design - Firewalls

    - by user3081239
    I am designing a campus network, and the design looks like this: LINX is The London Internet Exchange and JANET is Joint Academic Network. My goal is an almost-fully redundant with high availability, because it will have to support about 15k people, including academic staff, administrative staff and students. I have read some documents in the process , but I am still not sure about some aspects. I want to dedicate this one to firewalls: what are the driving factors in deciding to employ a dedicated firewall, instead of an embedded firewall in the border router? From what I can see, an embedded firewall has these advantages: Easier to maintain Better integration One less hop Less space requirement Cheaper Dedicated firewall has the advantage of being modular. Is there anything else? What am I missing?
