  • Rewriting URL's in codeigniter with url_title()?

    - by Craig Ward
    I am rewriting my website with codeigniter and have something I want to do but not sure it is possible. I have a gallery on my site powered by the Flickr API. Here is an example of the code I use to display the Landscape pictures: <?php foreach ($landscapes->photoset->photo as $l->photoset->photo) : ?> <a >photoset->photo->farm ?>/<?php echo $l->photoset->photo->server ?>/<?php echo $l->photoset->photo->id ?>/<?php echo $l->photoset->photo->secret ?>/<?php echo $l->photoset->photo->title ?>'> <img class='f_thumb'>photoset->photo->farm ?>.static.flickr.com/<?php echo $l->photoset->photo->server ?>/<?php echo $l->photoset->photo->id ?>_<?php echo $l->photoset->photo->secret ?>_s.jpg' title='<?php echo $l->photoset->photo->title ?>' alt='<?php echo $l->photoset->photo->title ?>' /></a> <?php endforeach; ?> As you can see when a user clicks on a picture I pass over the Farm, Server, ID, Secret and Title elements using URI segments and build the page in the controller using $data['farm'] = $this->uri->segment(3); $data['server'] = $this->uri->segment(4); $data['id'] = $this->uri->segment(5); $data['secret'] = $this->uri->segment(6); $data['title'] = $this->uri->segment(7); Everything works and is fine but the URL’s are a tad long, example “http://localhost:8888/wip/index.php/gallery/focus/3/2682/4368875046/e8f97f61d9/Old Mill House in Donegal” Is there a way to rewrite the URL so its more like “http://localhost:8888/wip/index.php/gallery/focus/Old_Mill_House_in_Donegal” I was looking at using: $url_title = $this->uri->segment(7); $url_title = url_title($url_title, 'underscore', TRUE); But I don’t seem to be able to get it to work. Any ideas?

  • help with grouping and sorting for TreeView in xaml

    - by danhotb
    I am having problems getting my head around grouping and sorting in xaml and hope someone can get me straightened out! I have creaed an xml file from a tree of files and folders (just like windows explorer) that can be serveral levels deep. I have bound a TreeView control to an xml datasource and it works great! It sorts everything alphabetically but ... I would like it to sort all folders first then all files, rather than folders listed with files, as it does now. the xml : if you load this to a treeviw it will display the two files before the folder because they are first in alpha-order. here is my code: <!-- This will contain the XML-data. --> <XmlDataProvider x:Key="xmlDP" XPath="*"> <x:XData> <Select_Project /> </x:XData> </XmlDataProvider> <!-- This HierarchicalDataTemplate will visualize all XML-nodes --> <HierarchicalDataTemplate DataType="project" ItemsSource ="{Binding}"> <TextBlock Text="{Binding XPath=@name}" /> </HierarchicalDataTemplate> <HierarchicalDataTemplate DataType="folder" ItemsSource ="{Binding}"> <TextBlock Text="{Binding XPath=@name}" /> </HierarchicalDataTemplate> <HierarchicalDataTemplate DataType="file" ItemsSource ="{Binding}"> <TextBlock Text="{Binding XPath=@name}" /> </HierarchicalDataTemplate> <CollectionViewSource x:Key="projectView" Source="{StaticResource xmlDP}"> <CollectionViewSource.SortDescriptions> <!-- ADD SORT DESCRIPTION HERE --> </CollectionViewSource.SortDescriptions> </CollectionViewSource> <TreeView Margin="11,79.992,18,19.089" Name="tvProject" BorderThickness="1" FontSize="12" FontFamily="Verdana"> <TreeViewItem ItemsSource="{Binding Source={StaticResource xmlDP}, XPath=*}" Header="Project"/> </TreeView>

  • Cookies not present after using XMLHttpRequest

    - by Joe B
    I'm trying to make a bookmarklet to download videos off of YouTube, but I've come across a little problem. To detect the highest quality video available, I use a sort of brute force method, in which I make requests using the XMLHttpRequest object until a 404 isn't returned (I can't do it until a 200 ok is returned because YouTube redirects to a different server if the video is available, and the cross-domain policy won't allow me to access any of that data). Once a working URL is found, I simply set window.location to the URL and the download should start, right? Wrong. A request is made, but for reasons unknown to me, the cookies are stripped and YouTube returns a 403 access denied. This does not happen if the XML requests aren't made before it, i.e. if I just set the window.location to the URL everything works fine, it's when I do the XMLHttpRequest that the cookies aren't sent. It's hard to explain so here's the script: var formats = ["37", "22", "35", "34", "18", ""]; var url = "/get_video?video_id=" + yt.getConfig('SWF_ARGS')['video_id'] + "&t=" + (unescape(yt.getConfig('SWF_ARGS')['t'])) + "&fmt="; for (var i = 0; i < formats.length; i++) { xmlhttp = new XMLHttpRequest; xmlhttp.open("HEAD", url + formats[i], false); xmlhttp.send(null); if (xmlhttp.status != 404) { document.location = url + formats[i]; break } } That script does not send the cookies after setting the document.location and thus does not work. However, simply doing this: document.location = /get_video?video_id=" + yt.getConfig('SWF_ARGS')['video_id'] + "&t=" + (unescape(yt.getConfig('SWF_ARGS')['t'])) DOES send the cookies along with the request, and does work. The only downside is I can't automatically detect the highest quality, I just have to try every "fmt" parameter manually until I get it right. So my question is: why is the XMLHttpRequest object removing cookies from subsequent requests? This is the first time I've ever done anything in JS by the way, so please, go easy on me. ;)

  • Fail to load NPAPI plugin in Google Chrome on Mac OS X

    - by Roman
    I have been trying to get Google Chrome (6.0.401.1 dev) on Mac OS X to load an NPAPI plugin without success so far. I have been working around the npsimple example from here: http://git.webvm.net/?p=npsimple. Using gcc on Mac and VC++ 2008 on Windows I managed to get it running on Safari and Firefox on Mac OS X and Firefox and Google Chrome on Windows, but not on Google Chrome on Mac OS X. When trying to debug Google Chrome on Mac OS X it seemed Google Chrome was briefly dyld-loading (and immediately dyld-unloading) the plugin on startup, but without actually looking-up any symbols within the plugin or calling any of the functions. It seemed to be doing that for every plugin, though. Also, when loading a page with the embed-tag for the plugin, Google Chrome did not seem to even dyld-load the plugin and no functions were called (not even NP_GetEntryPoints). Google Chrome also does not output any error message, it just simply does not load the plugin. I am not sure I caught everything with gdb because of Google Chrome using different processes, but I have also tried all the switches like --no-sandbox, --single-process and --plugin-startup-dialog (which incidentally does not seem to work at all on Mac OS X). I also made sure the architecture of the binary matches (i.e. 32-bit for Google Chrome). Has anybody had similar problems before? Is there anything I am missing here, like a gcc switch when compiling or something? Any help would be greatly appreciated.

  • How to separate ear classloader and system classloader in JBoss 6?

    - by dskiles
    I'm trying to upgrade from JBoss 4.2.1 to JBoss 6. In JBoss 4.2.1, we are manually deploying our application as an exploded war and everything works beautifully. I'm running into problems because the application that I am trying to deploy uses versions of 3rd party libraries that are older than the ones that JBoss 6 now includes by default. The result of this is that I'm getting classloader conflicts all over the place and the application won't even start. At present, I have tried using the JBoss Classloading Documentation as well as the scanty bits of documentation for jboss-classloading.xml and haven't had any success. Has anyone out there managed to do this successfully? If you have, how did you do it? I've included a stack trace below in case it offers any useful information. Caused by: java.lang.Error: Error visiting "/C:/jboss6/server/default/deploy/app.war/WEB-INF/lib/jaxb-xjc-2.1.12.jar/1.0/com/sun/codemodel/JConditional.class" at org.jboss.classloading.plugins.vfs.VFSResourceVisitor.visit(VFSResourceVisitor.java:268) [jboss-classloading-vfs.jar:2.2.0.Alpha9] at org.jboss.vfs.VirtualFile.visit(VirtualFile.java:407) [jboss-vfs.jar:3.0.0.CR5] at org.jboss.vfs.VirtualFile.visit(VirtualFile.java:409) [jboss-vfs.jar:3.0.0.CR5] at org.jboss.vfs.VirtualFile.visit(VirtualFile.java:409) [jboss-vfs.jar:3.0.0.CR5] at org.jboss.vfs.VirtualFile.visit(VirtualFile.java:409) [jboss-vfs.jar:3.0.0.CR5] at org.jboss.vfs.VirtualFile.visit(VirtualFile.java:409) [jboss-vfs.jar:3.0.0.CR5] at org.jboss.vfs.VirtualFile.visit(VirtualFile.java:395) [jboss-vfs.jar:3.0.0.CR5] at org.jboss.classloading.plugins.vfs.VFSResourceVisitor.visit(VFSResourceVisitor.java:102) [jboss-classloading-vfs.jar:2.2.0.Alpha9] at org.jboss.deployers.vfs.plugins.classloader.VFSDeploymentClassLoaderPolicyModule.visit(VFSDeploymentClassLoaderPolicyModule.java:181) [:2.2.0.Alpha8] at org.jboss.scanning.plugins.DeploymentUnitScanner.scan(DeploymentUnitScanner.java:111) [:1.0.0.Alpha7] at org.jboss.scanning.spi.helpers.UrlScanner.scan(UrlScanner.java:96) [:1.0.0.Alpha7] at org.jboss.scanning.deployers.ScanningDeployer.deploy(ScanningDeployer.java:90) [:1.0.0.Alpha7] at org.jboss.deployers.plugins.deployers.DeployerWrapper.deploy(DeployerWrapper.java:179) [:2.2.0.Alpha8] ... 41 more

  • NSFILEMANAGER CRASHING IN APP DELEGATE

    - by theiphoneguy
    I have this code in a method called from applicationDidFinishLaunching. It works in the simulator, but crashes on the iPhone. There are about 1,600 2KB mp3 files being copied in this operation. If I try to instantiate the app multiple times, it will eventually copy more each time until the app eventually will start without crashing. I am releasing everything I allocate. I have about 20GB disk space free on the iPhone. If I progressively comment out code and run it on the iPhone, the copyItemAtPath seems to be the suspect. (void)createCopyOfAudioFiles:(BOOL)force { @try { NSError *error; NSString *component; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSFileManager *fileManager = [[NSFileManager alloc] init]; NSEnumerator *enumerator = [[[NSBundle mainBundle]pathsForResourcesOfType:@"mp3" inDirectory:nil] objectEnumerator]; while ((component = [enumerator nextObject]) != nil) { NSArray *temp = [component componentsSeparatedByString:@".app/"]; NSString *file = [NSString stringWithFormat:@"%@", [temp objectAtIndex:1]]; NSString *writableAudioPath = [documentsDirectory stringByAppendingPathComponent:file]; BOOL success = [fileManager fileExistsAtPath:writableAudioPath]; if (success &amp;&amp; !force) { continue; } else if (success &amp;&amp; force) { success = [fileManager removeItemAtPath:writableAudioPath error:&amp;error]; } success = [fileManager copyItemAtPath:component toPath:writableAudioPath error:&amp;error]; if (!success) { @throw [NSException exceptionWithName:[error localizedDescription] reason:[error localizedFailureReason] userInfo:nil]; } } [fileManager release]; } @catch (NSException *exception) { NSLog(@"%@", exception); @throw [NSException exceptionWithName:exception.name reason:exception.reason userInfo:nil]; } @finally { } }

  • AjaxControlToolkit TabContainer with weird rendering behavior

    - by sohum
    I've built a web application that contains a page that uses the AjaxControlToolkit's TabContainer/TabPanel objects. I've developed a custom stylesheet, as well. I'm developing using Visual Studio 2010. The following is the behavior of my application: VS2010 Development Server (localhost:XXXXX): Works as expected with the custom stylesheet. Local IIS: The TabContainer rendered but the stylesheet wasn't applied. I fixed this by doing a CTRL+F5. It seems that IIS caches stylesheets pretty aggressively. Remote Server: The TabContainer and TabPanel are completely hidden. Looking at the HTML, all of them have their visibility set to hidden. The way I got my files onto my remote server were as follows (I haven't yet set up WebDAV or remote publishing because the server is a Windows 7 box and as far as I am aware does not support FrontPage Extensions): The entire solution is under source code control (SVN). Checked in all pending changes (including projects, aspx files, css, AjaxControlToolkit binaries) Synced on the server. Rebuilt everything on server. Deployed to local IIS on server (which is externally accessible). Both on the local IIS on the server and the development server on the server, the TabContainers are completely hidden. Looking at the SVN status on the server project, only the "AjaxControlToolkit.dll" is under source-code control. All the locale-specific DLLs are not on the server. Could this be a potential issue? I'm not sure what's going on and would appreciate any help. Thanks!

  • Named pipe blocking with user nobody

    - by dnagirl
    I have 2 short scripts. The first, an awk script, processes a large file and prints to a named pipe 'myfifo.dat'. The second, a Perl script, runs a LOAD DATA LOCAL INFILE 'myfifo.dat'... command. Both of these scripts work when run locally like so: lee.awk big.file & lee.pl However, when I call these scripts from a PHP webpage, the named pipe blocks: $awk="/path/to/lee.awk {$_FILES['uploadfile']['tmp_name']} &"; $sql="/path/to/lee.pl"; if(!exec($awk,$return,$err)) throw new ZException(print_r($err,true)); //blocks here if(!exec($sql,$return,$err)) throw new ZException(print_r($err,true)); If I modify the awk and Perl scripts so that they write and read to a normal file, everything works fine from PHP. The permissions on the fifo and the normal file are 666 (for testing purposes). These operations run much more quickly through a named pipe, so I'd prefer to use one. Any ideas how to unblock it? ps. In case you're wondering why I'm going to all this aggravation, see this SO question.

  • UITableViewController not redrawing new cell text label after popViewControllerAnimated

    - by crunchyt
    I have a problemetic UITableViewController fails to redraw an updated cell after a child view is removed. Here's what's happening. After changing data in a child view, the parent view controller reloads the source data array and runs [tableView reloadData] via a PostNotification. After this triggers, I use popViewControllerAnimated to return to the parent UITableViewController (this pops the child view off the stack, and reveals the controller one level up). However, my updated data does not appear in the parent view controller! According to the debugger, the cell's label has been updated, but the visible label does not change. However, if I scroll-flick the table, momentarily moving the updated cell out of view, when it reappears the label is updated! I also try calling [tableView reloadData] via viewWillAppear but the issue still persists. Here is some additional info that may be helpful. I have a 3 views structured like this: 1/ SettingsViewController : UITableViewController 2/ -- UserView : UITableViewController 3/ ---- UserDetailsView : UIViewController <UIActionSheetDelegate> I am calling UserDetailsView from inside UserView as follows: UserDetailsView *userDetailsView = [[UserDetailsView alloc] init]; [self.navigationController pushViewController:userDetailsView animated:YES]; If I return to the top-most controller (SettingsViewController) and then load the problematic controller (UserView), everything is drawn correctly. It is only when returning from a child view that this issue occurs. Thank you in advance for your suggestions.

  • Which Computer Organization & Architecture book is good for me?

    - by claws
    I'm always interested in learning the inner working of things. I started with C programming and then learnt Operating systems (from stallings) and then linkers & loaders and then assembly language after reading these now I want to go into little more depth. Computer Architecture. I feel that makes everything clear. As per SO archives these are the two good books: Computer Architecture: A Quantitative Approach, 4th Edition Computer Organization and Design, Fourth Edition, ~ David A. Patterson, John L. Hennessy But I've browsed through the contents of these books and found that they don't exactly meet my needs. I want to learn more about caches, Memory Management Unit , mapping b/w virtual memory & physical memory I'm no way interested in other ISAs like MIPS etc.. I'm IA32 and X86-64 fan and I want to stick to it. I'm not a hardware developer I don't want to details like circuit diagrams or How is L1, L2 & L3 caches are implemented? I want to know the parallel processing technologies like HyperThreading at the architecture level but again I don't want to design them. I liked the table of Contents of - Computer Architecture: A Quantitative Approach, 4th Edition but Quantitave Approach? Seriously?? I want to know the details of current technologies and I dont want to spend reading 200 pages of outdated old technologies ( I experienced this while learning ASM}

  • How can I inject an object into an WCF IErrorHandler implementation with Castle Windsor?

    - by Michael Johnson
    I'm developing a set of services using WCF. The application is doing dependency injection with Castle Windsor. I've added an IErrorHandler implementation that is added to services via an attribute. Everything is working thus far. The IErrorHandler object (of a class called FaultHandler is being applied properly and invoked. Now I'm adding logging. Castle Windsor is set up to inject the logger object (an instance of IOurLogger). This is working. But when I try to add it to FaultHandler my logger is null. The code for FaultHandler looks something like this: class FaultHandler : IErrorHandler { public IOurLogger logger { get; set; } public bool HandleError(Exception error) { logger.Write("Exception type {0}. Message: {1}", error.GetType(), error.Message); // Let WCF handle things its way. We only want to log. return false; } public void ProvideFault(Exception error, MessageVersion version, Message fault) { } } This throws it's own exception, since logger is null when HandleError() is called. The logger is being successfully injected into the service itself and is usable there, but for some reason I can't use it in FaultHandler. Update: Here is the relevant part of the Windsor configuration file (edited to protect the innocent): <configuration> <components> <component id="Logger" service="Our.Namespace.IOurLogger, Our.Namespace" type="Our.Namespace.OurLogger, Our.Namespace" /> </components> </configuration>

  • How can I debug why this click handler never fires?

    - by tixrus
    I am going to be excrutiatingly detailed here. I am using Firefox 3.6.3 on Max OSX with Firebug 1.5.3. I have two versions of a project, one which works and one with a bug. One I downloaded and one I typed by hand. Take a guess which one doesn't work. They should be the same except that mine uses a newer version of jQuery and the files are named differently. jQuery version is not the issue. I made mine use the older jquery and I made the working one use the newer jquery. Either way, mine still broke and the downloaded one still works. I've busted my eyes trying to see how these projects are different. The only thing I don't want to do is copy the working code to the busted code because I need to be able to figure this stuff out when it is my own unique code causing similar issues. There are no errors that I can see in Firebug in my code, in fact, 2/3 of it works just fine. just the second button does nothing. So I wanted to step through. These are always eyeball errors and I really suck at seeing them. I put it on a public server. http://colleenweb.com/jqtests/ex71.html And I want to debug ex71.js If you firebug the working one and set a break point at line 13 in ex71.js the variable json has the expected values when you click on the second button. But If you firebug this one, it never gets there. I've been over the html and all the names of everything seem to match up. I also wonder why the buttons aren't right justified but that's a css thing. Please tell me what I'm missing, and more importantly, what tool/technique I could use to find these types of bugs.

  • T-SQL Right Joins to ALL Entries inc Selected Column

    - by Pace
    Hi Experts, I have the following Query which produces the output below; SELECT TBLUSERS.USERID, TBLUSERS.ADusername, TBLACCESSLEVELS.ACCESSLEVELID, TBLACCESSLEVELS.AccessLevelName FROM TBLACCESSLEVELS INNER JOIN TBLACCESSRIGHTS ON TBLACCESSLEVELS.ACCESSLEVELID = TBLACCESSRIGHTS.ACCESSLEVELID INNER JOIN TBLUSERS ON TBLACCESSRIGHTS.USERID = TBLUSERS.USERID The output is this; 29 administrator 1 AllUsers 29 administrator 2 JobQueue 29 administrator 3 Telephone Directory Admin 29 administrator 4 Jobqueueadmin 29 administrator 5 UserAdmin 29 administrator 6 Product System 27 alan 1 AllUsers 97 andy 1 AllUsers 26 barry 1 AllUsers 26 barry 2 JobQueue 26 barry 3 Telephone Directory Admin 26 barry 4 Jobqueueadmin 26 barry 5 UserAdmin 26 barry 6 Product System 26 barry 7 Newseditor 26 barry 8 GreetingBoard What I would like to do is modify the query so I get all Access Levels regardless of weather there is an entry for that user. What I would also like to do is some sort of exist case so that I get output like the following; 29 administrator 1 AllUsers True 29 administrator 2 JobQueue True 29 administrator 3 Telephone Directory Admin True 29 administrator 4 Jobqueueadmin True 29 administrator 5 UserAdmin True 29 administrator 6 Product System True 29 administrator 7 Newseditor False 29 administrator 8 GreetingBoard False 27 alan 1 AllUsers True 27 alan 2 JobQueue False 27 alan 3 Telephone Directory Admin False 27 alan 4 Jobqueueadmin False 27 alan 5 UserAdmin False 27 alan 6 Product System False 27 alan 7 Newseditor False 27 alan 8 GreetingBoard False 97 andy 1 AllUsers True 97 andy 2 JobQueue False 97 andy 3 Telephone Directory Admin False 97 andy 4 Jobqueueadmin False 97 andy 5 UserAdmin False 97 andy 6 Product System False 97 andy 7 Newseditor False 97 andy 8 GreetingBoard False 26 Barry 1 AllUsers True 26 Barry 2 JobQueue True 26 Barry 3 Telephone Directory Admin True 26 Barry 4 Jobqueueadmin True 26 Barry 5 UserAdmin True 26 Barry 6 Product System True 26 Barry 7 Newseditor True 26 Barry 8 GreetingBoard True ......................................... So the rules are ALWAYS show ALL Entries for ACCESSLEVELS and where EXISTS in ACCESSRIGHTS produce a true / false to show this. I hope this makes sense and hopefully you dont need the table definitions as everything I need to work with is in the original Query. I just need a way of manipulating it slightly and getting the join in the right place. Thank you. Pace

  • remove a:hover using javascript (not using jquery... don't ask)

    - by Cyprus106
    I thought this would be pretty simple.... Basically, it's a 5-star rating system. When a user clicks, for example, three stars... I want to freeze those three stars right where they're at. I've been trying to simply remove the hover for the a href so it stays what it was at... maybe that's not the right method. I've exhausted absolutely everything I can think of... By the way this is straight javascript, not jquery or anything. It's crazy, I know but all of the JS was written straight.... I've got this class: .star-rating li a{ display:block; width:25px; height: 25px; text-decoration: none; text-indent: -9000px; z-index: 20; position: absolute; padding: 0px; } .star-rating li a:hover{ background: url(images/alt_star.png) left bottom; z-index: 2; left: 0px; } .star-rating a:focus, .star-rating a:active{ border:0; -moz-outline-style: none; outline: none; } .star-rating a.one-star{ left: 0px; } .star-rating a.one-star:hover{ width:25px; } and this code: <ul class='star-rating'> <li><a href="#" onclick="javascript: vote(<?=$id;?>, 1); disableStars(); return false;" title='1 star out of 5' id="1s" class='one-star'>1</a></li>

  • Data Binding to an object in C#

    - by Allen
    Objective-c/cocoa offers a form of binding where a control's properties (ie text in a textbox) can be bound to the property of an object. I am trying to duplicate this functionality in C# w/ .Net 3.5. I have created the following very simple class in the file MyClass.cs: class MyClass { private string myName; public string MyName { get { return myName; } set { myName = value; } } public MyClass() { myName = "Allen"; } } I also created a simple form with 1 textbox and 1 button. I init'd one instance of Myclass inside the form code and built the project. Using the DataSource Wizard in Vs2008, i selected to create a data source based on object, and selected the MyClass assembly. This created a datasource entity. I changed the databinding of the textbox to this datasource; however, the expected result (that the textbox's contents would be "allen") was not achieved. Further, putting text into the textbox is not updating the name property of the object. I know i'm missing something fundamental here. At some point i should have to tie my instance of the MyClass class that i initialized inside the form code to the textbox, but that hasn't occurred. Everything i've looked at online seems to gloss over using DataBinding with an object (or i'm missing the mark entirely), so any help is great appreciated. ----Edit--- Utilizing what i learned by the answers, i looked at the code generated by Visual Studio, it had the following: this.myClassBindingSource.DataSource = typeof(BindingTest.MyClass); if i comment that out and substitute : this.myClassBindingSource.DataSource = new MyClass(); i get the expected behavior. Why is the default code generated by VS like it is? Assuming this is more correct than the method that works, how should i modify my code to work within the bounds of what VS generated?

    Hello, while starting JBoss 5.1.0.GA in virtual server machine on Debian (linux-VServer technology) I get the following error: ERROR [org.jboss.kernel.plugins.dependency.AbstractKernelController] (main) Error installing to Start: name=jboss.remoting:protocol=rmi,service=JMXConnectorServer state=Create mode=Manual requiredState=Installed java.io.IOException: Cannot bind to URL [rmi://10.1.2.11:1090/jmxconnector]: javax.naming.NoPermissionException [Root exception is java.rmi.ServerException: RemoteException occurred in server thread; nested exception is: java.rmi.AccessException: Registry.Registry.bind disallowed; origin /AA.BB.CC.DD is non-local host] where AA.BB.CC.DD is host machine name, 10.1.2.11 is vserver guest with JBoss and JBoss is started with -b 10.1.2.11 (I also tried -Djboss.bind.address=10.1.2.11 - the same result). 10.1.2.11 is bound to dummy2 interface on host (serving 10.1.2.1 network). The root exception is strange - why JBoss wants to bind to host address AA.BB.CC.DD? There were no problems with 4.2.3.GA on the same machine, also started with -b 10.1.2.11. It starts correctly when no params present - binds to localhost and everything is ok, but it MUST be bound to 10.1.2.11 to be visible by Apache on another vserver guest, acting as proxy. I thought that it can be fixed by setting net.ipv4.conf.all.promote_secondaries=1 via sysctl (was 0) but it didn't help much. Has anyone had such problem? Regards, bart

  • Android: writing a file to sdcard

    - by Sumit M Asok
    I'm trying to write a file from an Http post reply to a file on the sdcard. Everything works fine until the byte array of data is retrieved. I've tried setting WRITE_EXTERNAL_STORAGE permission in the manifest and tried many different combinations of tutorials I found on the net. All I could find was using the openFileOutput("",MODE_WORLD_READABLE) method, of the activity but how my app writes file is by using a thread. Specifically, a thread is invoked from another thread when a file has to be written, so giving an activity object didn't work even though I tried it. The app has come a long way and I cannot change how the app is currently written. Please, someone help me? CODE: File file = new File(bgdmanip.savLocation); FileOutputStream filecon = null; filecon = new FileOutputStream(file); // bgdmanip.savLocation holds the whole files path byte[] myByte; myByte = Base64Coder.decode(seReply); Log.d("myBytes", String.valueOf(myByte)); bos.write(myByte); filecon.write(myByte); myvals = x * 11024; seReply is a string reply from HttpPost response. the second set of code is looped with reference to x. the file is created but remains 0 bytes

  • Getting Android SDK WebView and TabWidget to play nice

    - by jdandrea
    I’m taking the HelloTabWidget Android example and trying two things: Moving the tabs to the bottom vs. the top (if that’s even desirable from an Android UI POV) Making each tab show a particular WebView in the space above I’ve got this for a layout (high level): <TabHost> <LinearLayout> <FrameLayout> <WebView/> <WebView/> <WebView/> <WebView/> <WebView/> </FrameLayout> <TabWidget/> </LinearLayout> </TabHost> Everything has a width/height set to fill_parent except for the TabWidget which has its layout_height set to wrap_content (and the layout_gravity set to bottom). First thing I noticed is that WebViews don’t show anything until all the parents have width/height set to fill_parent. However, once I do that, they fill the entire display, obscuring the TabWidget. Is there some other trick to making these two views play nicely together?

  • Binding Data to DataGridView in VB.Net

    - by Peter
    Hi, I have a bit of code which loads data from a stored procedure in MS SQL Server and then loads the data to a datagridview, which works fine. What i want is for the code that connects / loads the data to sit in my Database Class and then everything associated with the datagridview to be stored in my Form but i am having problems passing the contents of the bindingsource over to the Form from the Database Class. Form1 Public Class Form1 Dim myDatabaseObj As New Class1() Dim bindingSource1 As New BindingSource() Dim connectString As New SqlConnection Dim objDataAdapter As New SqlDataAdapter Dim table As New DataTable() Dim tabletest As New DataTable() Private Sub loadCompanyList() Try Me.dgv_CompanyList.DataSource = Me.bindingSource1 getCompanyList() Catch ex As NullReferenceException End Try End Sub Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load loadCompanyList() End Sub End Class Database Class When i try place the getCompanyList() in a class and then create a new object that references the Form() it does not seem to return any value from the table to the MyForm.BindingSource1.Datasource meaning my datagridview displays not data. ..... Private Sub getCompanyList() Try Dim myForm as new Form() connect_Transaction_Database() objDataAdapter.SelectCommand = New SqlCommand() objDataAdapter.SelectCommand.Connection = connectString objDataAdapter.SelectCommand.CommandText = "sp_GetCompanyList" objDataAdapter.SelectCommand.CommandType = CommandType.StoredProcedure Dim commandBuilder As New SqlCommandBuilder(Me.objDataAdapter) Dim table As New DataTable() table.Locale = System.Globalization.CultureInfo.InvariantCulture Me.objDataAdapter.Fill(table) **MyForm.bindingSource1.DataSource = table** Catch ex As DataException MsgBox(ex.Message) Catch ex As NullReferenceException MsgBox(ex.Message) End Try disconnect_Transaction_Database() End Sub If anyone could help. Thank you. Peter

  • UniqueConstraint in EmbeddedConfiguration

    - by LantisGaius
    I just started using db4o on C#, and I'm having trouble setting the UniqueConstraint on the DB.. here's the db4o configuration static IObjectContainer db = Db4oEmbedded.OpenFile(dbase.Configuration(), "data.db4o"); static IEmbeddedConfiguration Configuration() { IEmbeddedConfiguration dbConfig = Db4oEmbedded.NewConfiguration(); // Initialize Replication dbConfig.File.GenerateUUIDs = ConfigScope.Globally; dbConfig.File.GenerateVersionNumbers = ConfigScope.Globally; // Initialize Indexes dbConfig.Common.ObjectClass(typeof(DAObs.Environment)).ObjectField("Key").Indexed(true); dbConfig.Common.Add(new Db4objects.Db4o.Constraints.UniqueFieldValueConstraint(typeof(DAObs.Environment), "Key")); return dbConfig; } and the object to serialize: class Environment { public string Key { get; set; } public string Value { get; set; } } everytime I get to commiting some values, an "Object reference not set to an instance of an object." Exception pops up, with a stack trace pointing to the UniqueFieldValueConstraint. Also, when I comment out the two lines after the "Initialize Indexes" comment, everything runs fine (Except you can save non-unique keys, which is a problem)~ Commit code (In case I'm doing something wrong in this part too:) public static void Create(string key, string value) { try { db.Store(new DAObs.Environment() { Key = key, Value = value }); db.Commit(); } catch (Db4objects.Db4o.Events.EventException ex) { System.Console.WriteLine (DateTime.Now + " :: Environment.Create\n" + ex.InnerException.Message +"\n" + ex.InnerException.StackTrace); db.Rollback(); } } Help please? Thanks in advance~

  • weird result with c# winForms array of Lists

    - by jello
    so I'm trying to store values in an array of Lists in C# winForms. In the for loop in which I make the sql statment, everything works fine: the message box outputs a different medication name each time. for (int i = 0; i < numberOfMeds; i++) { queryStr = "select * from biological where medication_name = '" + med_names[i] + "' and patient_id = " + patientID.patient_id; using (var conn = new SqlConnection(connStr)) using (var cmd = new SqlCommand(queryStr, conn)) { conn.Open(); using (SqlDataReader rdr = cmd.ExecuteReader()) { while (rdr.Read()) { medObject.medication_date = (DateTime)rdr["patient_history_date_bio"]; medObject.medication_name = rdr["medication_name"].ToString(); medObject.medication_dose = Convert.ToInt32(rdr["medication_dose"]); medsList[i].Add(medObject); } } conn.Close(); MedicationTimelineClass medObjectx = medsList[i][0] as MedicationTimelineClass; MessageBox.Show(medObjectx.medication_name); } } but then, when I take the message box code out of the loop, meaning that the array of Lists is supposed to be populated, I always get the same value: the last value entered. the same medication name, no matter what number I put between those brackets. It's like if the whole array of Lists is populated with the same data. for (int i = 0; i < numberOfMeds; i++) { queryStr = "select * from biological where medication_name = '" + med_names[i] + "' and patient_id = " + patientID.patient_id; using (var conn = new SqlConnection(connStr)) using (var cmd = new SqlCommand(queryStr, conn)) { conn.Open(); using (SqlDataReader rdr = cmd.ExecuteReader()) { while (rdr.Read()) { medObject.medication_date = (DateTime)rdr["patient_history_date_bio"]; medObject.medication_name = rdr["medication_name"].ToString(); medObject.medication_dose = Convert.ToInt32(rdr["medication_dose"]); medsList[i].Add(medObject); } } conn.Close(); } } MedicationTimelineClass medObjectx = medsList[0][0] as MedicationTimelineClass; MessageBox.Show(medObjectx.medication_name); what's going on here?

  • C# XMLRPC Multi Threaded newPost something is not right

    - by user1047463
    I recently decided to get my feet wet with c# multi threading and my progress was good until now. My program uses XML-RPC to create new posts on wordpress. When I run my app on the localhost everything works fine and i successfully able to create new posts on wordpress using a multi threaded approach. However when I try to do the same with a wordpress installed on a remote server , new posts won't appear, so when i go to see all posts, the total number of posts remains unchanged. Another thing to note is the function that creates a new post does return the ID of a supposedly created posts. But as I mentioned previously the new posts are not visible when I try to access them in admin menu. Since I'm new to the multithreading I was hoping some of you guys can help me and check if I'm doing anything wrong. Heres the code that creates threads and calls create post function. foreach (DataRow row in dt.Rows) { Thread t = null; t = new Thread(createPost); lock (t) { t.Start(); } } public void createPost() { string postid; try { icp = (IcreatePost)XmlRpcProxyGen.Create(typeof(IcreatePost)); clientProtocol = (XmlRpcClientProtocol)icp; clientProtocol.Url = xmlRpcUrl; postid = icp.NewPost(1, blogLogin, blogPass, newBlogPost, 1); currentThread--; threadCountLabel.Invoke(new MethodInvoker(delegate { threadCountLabel.Text = currentThread.ToString(); })); } catch (Exception ex) { MessageBox.Show( createPost ERROR ->" + ex.Message); } }

  • Android media thumbnails. Serious issues?

    - by Ralphleon
    I've been playing with android's thumbnails for a while now, and I've seen some inconsistencies that make me want to scream. My goal is to have a simple list of all Images (and a separate list for video) with the thumbnail and filename. Device: HTC Evo (fresh from Google I/o) First off: http://androidsamples.blogspot.com/2009/06/how-to-display-thumbnails-of-images.html That code doesn't seem to work at all, thumbnails are duplicated... some with the "mirror" effect and some without. Also some won't load and just display a black square. I've tried rebuilding the thumbnails by deleting the "alblum thumbs" directory from the SD card. HTC's gallery application seem to show everything fine. This approach seems to work: Bitmap thumb = MediaStore.Images.Thumbnails.getThumbnail( getContentResolver(), id, MediaStore.Video.Thumbnails.MICRO_KIND, null); imageView.setImageBitmap(curThumb); where id is the original images id and imageView is some image view. This is great! But, strangely, way too slow to be used inside a SimpleViewBinder. Next approach: String [] proj = {MediaStore.Images.Thumbnails._ID}; Cursor c = managedQuery(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, proj, MediaStore.Images.Thumbnails.IMAGE_ID + "=" +id , null, null); if (c != null && c.moveToFirst()) { Uri thumb = Uri.withAppendedPath(mThumbUri,c.getLong(0)+""); imageView.setImageURI(thumb); } I should explain that I feel the needed WHERE condition is required because there doesn't seem to be any guarantee that your uri will have the same ID for both a thumbnail and its parent image. This works for all of the current images, but as soon as I start adding pictures with the camera they show up as blank! Debugging shows a dreaded: SkImageDecoder::Factory returned null error and the URI is returned as invalid. These are the same images that work with the previous call. Can anyone either catch my logical failure or point me to some working code?
