  • Where to put a textfile I want to use in eclipse?

    - by Jayomat
    hi there, I need to read a text file when I start my program. I'm using eclipse and started a new java project. In my project folder I got the "src" folder and the standard "JRE System Library"... I just don't know where to put the text file. I cannot use a "hard coded" path because the text file needs to be included with my app... I also tried to create a new folder like "Files" and use the pathe "Files/staedteliste.txt".. doesn't work too... I use the following code to read the file, but I get this error: Error:java.io.FileNotFoundException:staedteliste.txt(No such file or directory) import java.io.BufferedReader; import java.io.FileReader; import java.io.IOException; import java.util.ArrayList; public class Test { ArrayList<String[]> values; public static void main(String[] args) { // TODO Auto-generated method stub loadList(); } public static void loadList() { BufferedReader reader; String zeile = null; try { reader = new BufferedReader(new FileReader("staedteliste.txt")); zeile = reader.readLine(); ArrayList<String[]> values = new ArrayList<String[]>(); while (zeile != null) { values.add(zeile.split(";")); zeile = reader.readLine(); } System.out.println(values.size()); System.out.println(zeile); } catch (IOException e) { System.err.println("Error :"+e); } } } thx for help!

  • Singleton Issues in iOS http client

    - by Andrew Lauer Barinov
    I implemented an HTTP client is iOS that is meant to be a singleton. It is a subclass of AFNetworking's excellent AFHTTPClient My access method is pretty standard: + (LBHTTPClient*) sharedHTTPClient { static dispatch_once_t once = 0; static LBHTTPClient *sharedHTTPClient = nil; dispatch_once(&once, ^{ sharedHTTPClient = [[LBHTTPClient alloc] initHTTPClient]; }); return sharedHTTPClient; } // my init method - (id) initHTTPClient { self = [super initWithBaseURL:[NSURL URLWithString:kBaseURL]]; if (self) { // Sub class specific initializations } return self; } Super's init method is very long, and can be found here However the problem I experience is when the dispatch_once queue is run, the app locks and become unresponsive. When I step through code, I notice that it locks on dispatch_once and then remains frozen. Is this something to do with the main thread locking down? How come it stays locked like that? Also, none of the HTTP client methods fire. Stepping through the code some more, I find this line in dispatch/once.h is where the app locks down: DISPATCH_INLINE DISPATCH_ALWAYS_INLINE DISPATCH_NONNULL_ALL DISPATCH_NOTHROW void _dispatch_once(dispatch_once_t *predicate, dispatch_block_t block) { if (DISPATCH_EXPECT(*predicate, ~0l) != ~0l) { dispatch_once(predicate, block); // App locks here } }

  • Service Accounts LastLogonTimestamp

    - by Ryan Ries
    In an Active Directory domain, if I configure a Windows service on a domain member computer to start with an AD user account (aka "ye olde service account",) and the then the service stays running but I don't restart the service or reboot the machine for a year... does the LastLogonTimestamp of the service account's user object continue to update? Edit: If you say "it depends on the service," then use MS SQL Server as an example. I set MSSQL Engine to run as contoso\sql-service. Then I leave it alone for a year.

  • MonoRail ActiveRecord - The UPDATE statement conflicted with the FOREIGN KEY SAME TABLE

    - by Justin
    Hey all, I'm new to MonoRail and ActiveRecord and have inherited an application that I need to modify. I have a Category table (Id, Name) and I'm adding a ParentId FK which references the Id in the same table so that you can have parent/child category relationships. I tried adding this to my Category model class: [Property] public int ParentId { get; set; } I also tried doing it this way: [BelongsTo("ParentId")] public Category Parent { get; set; } When I call a method to get all parent categories (they have a null ParentId), it works fine: public static Category[] GetParentCategories() { var criteria = DetachedCriteria.For<Core.Models.Category>(); return (FindAllByProperty("ParentId", null)); } However, when I call a method to get all child categories within a specific category, it errors out: public static Category[] GetChildCategories(int parentId) { var criteria = DetachedCriteria.For<Core.Models.Category>(); return (FindAllByProperty("ParentId", parentId)); } The error is: "The UPDATE statement conflicted with the FOREIGN KEY SAME TABLE constraint \"FK_Category_ParentId\". The conflict occurred in database \"UCampus\", table \"dbo.Category\", column 'Id'.\r\nThe statement has been terminated." I'm hard-coding in the parentId parameter as 1 and I'm 100% sure it exists as an id in the Category table so I don't know why it'd give this error. Also, I'm doing a select, not an update, so what is going on here?? Thanks for any input on this, Justin

  • wxpython GUI and multiprocessing - how to send data back from the long running process

    - by wxpydon
    Hello everyone, Trying to run a time consuming task from a wxpython GUI. The basic idea is to start the long time task from the GUI (pressing a button) and then, a static text on the dialog should be updated from it. First I tried some threading (http://wiki.wxpython.org/LongRunningTasks and many other resourses seen), and I want to show back the messages using Publisher.class. It didn't went so well, after a message or two, the GUI seems to frozen. Now I want to achieve that with multiprocessing. I have this method inside my 'GUI' class: def do_update(self, e): self.txt_updatemsg.SetLabel("Don't stop this \n") ... pub = Publisher() # i tried also calling directly from dbob object # Publisher() is a singleton so this must be useless? pub.subscribe(self.__update_txt_message, ('updatedlg', 'message')) dbob = dbutils.DBUtils() # DBUtils is the class with 'long time' tasks dbob.publisher = pub p = Process(target=self.do_update_process, args=(dbob,)) p.start() while p.is_alive: wx.Yield def do_update_process(self, dbob): dbob.do_update() __update_txt_message is a simple function what sets the static text on dialog. Question is: how can I send back some text messages from this Process (just simple text, that's all I need) Thanks guys!

  • Can ElementTree be told to preserve the order of attributes?

    - by dmckee
    I've written a fairly simple filter in python using ElementTree to munge the contexts of some xml files. And it works, more or less. But it reorders the attributes of various tags, and I'd like it to not do that. Does anyone know a switch I can throw to make it keep them in specified order? Context for this I'm working with and on a particle physics tool that has a complex, but oddly limited configuration system based on xml files. Among the many things setup that way are the paths to various static data files. These paths are hardcoded into the existing xml and there are no facilities for setting or varying them based on environment variables, and in our local installation they are necessarily in a different place. This isn't a disaster because the combined source- and build-control tool we're using allows us to shadow certain files with local copies. But even thought the data fields are static the xml isn't, so I've written a script for fixing the paths, but with the attribute rearrangement diffs between the local and master versions are harder to read than necessary. This is my first time taking ElementTree for a spin (and only my fifth or sixth python project) so maybe I'm just doing it wrong. Abstracted for simplicity the code looks like this: tree = elementtree.ElementTree.parse(inputfile) i = tree.getiterator() for e in i: e.text = filter(e.text) tree.write(outputfile) Reasonable or dumb?

  • UITableView madness

    - by kesrut
    Hello, I'm new to iPhone application development. I'm trying to understand how to use UITableView. I'm wrote simple code: - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return 1 ; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *MyIdentifier = @"MyIdentifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MyIdentifier] autorelease]; } cell.textLabel.text = @"Hello"; return cell; } UITable shows content, but if i'm drag table contents my application terminates.

  • Does Exchange 2010 lift the restriction that DL addresses must be in Active Directory?

    - by Justin Grant
    We'd like to enable end-users to be able to create and maintain their own email distribution lists in Exchange 2010, where those lists may include users inside the company but also customers, partners, etc. who are outside the company. One of the limitations in Exchange 2007 (see this question) was that any member of a DL had to have an entry in active directory. You couldn't just take a group of email addresses (both inside and outside my company) and create an Exchange DL with those addresses without involving Active Directory admins to create entries for each external user. For a company creating hundreds of small mailing lists every month, this was an unacceptable IT expense. So we had to use a separate mailing list solution (GNU mailman) for DLs which included external users. Is this limitation relaxed in Exchange 2010 so we can throw away GNU mailman and use Exchange instead?

  • VS2010 and CSS: What is the best strategy to individually position form controls

    - by George
    OK, I have a ton of controls on my page that I need to individually place. I need to set a margin here, a padding there, etc. None of these particular styles that I want to apply will be applied to more than control. What is the bets practice for determining at which level the style is placed, etc? OK, my choices are 1) External CSS file 1A) Using ClientIdMode = Auto (the default) I could assign a unique CssClass value to the ASP.NET control and, in the external CSS file, create a class selector that would only be applied to that one control. 1B) User Client ID = Predicatable In the external CSS file, I could determine what the ID will be for the controls of interest and create an ID selector (#ControlID{Style} ). However, I fear maintenance issues due to including/removing parent containers that would cause the ID to change. 1C) User Client ID = Static. I could choose static IDs for the controls such that I minimize the likelihood of a clash with auto generated IDs (perhaps by prefixing the ID with "StaticID_" and use an external stylesheet with ID selectors. 2) I could place the style right on the control. The only disadvantage here, as I see it, is that style info is brought down each time instead of being cached , which is what I'd get using an external CSS. If a style isn't resused, I personally don't see much benefit to placing it in an external file, though please explain why if you disagree. Is there moire of a reason that "It's nice to have all the CSS in one place?"

  • Removing PDF attachments via itext

    - by r00fus
    I'm trying to remove attachments from a number of my pdf files (I can extract via pdftk, so preserving them is not an issue). I coded the following based on an example found from a google search: import java.io.FileOutputStream; import java.io.IOException; import com.lowagie.text.*; import com.lowagie.text.pdf.*; class pdfremoveattachment { public static void main(String[] args) throws IOException, DocumentException { if (args.length < 2) { System.out.println("Usage: java PDFremoveAttachments source.pdf target.pdf"); System.exit(1); } PdfReader sourcePDF = new PdfReader(args[0]); removeAttachments(sourcePDF); FileOutputStream targetFOS = new FileOutputStream(args[1]); PdfStamper targetPDF = new PdfStamper(sourcePDF,targetFOS); targetPDF.close(); } public static void removeAttachments(PdfReader reader) { PdfDictionary catalog = reader.getCatalog(); // System.out.println(catalog.getAsDict(PdfName.NAME)); // this would print "null" PdfDictionary names = (PdfDictionary)PdfReader.getPdfObject(catalog.get(PdfName.NAMES)); // System.out.println(names.toString()); //this returns NPE if( names != null) { PdfDictionary files = (PdfDictionary) PdfReader.getPdfObject(names.get(PdfName.FILEATTACHMENT)); if( files!= null ){ for( Object key : files.getKeys() ){ files.remove((PdfName)key); } files = (PdfDictionary) PdfReader.getPdfObject(names.get(PdfName.EMBEDDEDFILES)); } if( files!= null ){ for( Object key : files.getKeys() ){ files.remove((PdfName)key); } reader.removeUnusedObjects(); } } } } If anyone knows how I might be able to remove attachments, I'd greatly appreciate a reply.

  • jQuery UI datepicker will not display - full code included

  • 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?

  • [C#] How to use delegate to perform callback between caller and web service helper class?

    - by codemonkie
    I have 2 classes A and B, where they belongs to the same namespace but resides in seperate files namely a.cs and b.cs, where class B essentially is a helper wrapping a web service call as follow: public class A { public A() // constructor { protected static B b = new B(); } private void processResult1(string result) { // come here when result is successful } private void processResult2(string result) { // come here when result is failed } static void main() { b.DoJobHelper(...); } } public class B { private com.nowhere.somewebservice ws; public B() { this.ws = new com.nowhere.somewebservice(); ws.JobCompleted += new JobCompletedEventHandler(OnCompleted); } void OnCompleted(object sender, JobCompletedEventArgs e) { string s; Guid taskID = (Guid)e.UserState; switch (s) { case "Success": // Call processResult1(); break; case "Failed": // Call processResult2(); break; default: break; } } public void DoJobHelper() { Object userState = Guid.NewGuid(); ws.DoJob(..., userState); } } (1) I have seen texts on the net on using delegates for callbacks but failed to apply that to my case. All I want to do is to call the appropriate processResult() method upon OnCompleted() event, but dunno how to and where to declare the delegate: public delegate void CallBack(string s); (2) There is a sender object passed in to OnCompleted() but never used, did I miss anything there? Or how can I make good use of sender? Any helps appreciated.

  • SYN flooding still a threat to servers?

    - by Rob
    Well recently I've been reading about different Denial of Service methods. One method that kind of stuck out was SYN flooding. I'm a member of some not-so-nice forums, and someone was selling a python script that would DoS a server using SYN packets with a spoofed IP address. However, if you sent a SYN packet to a server, with a spoofed IP address, the target server would return the SYN/ACK packet to the host that was spoofed. In which case, wouldn't the spoofed host return an RST packet, thus negating the 75 second long-wait, and ultimately failing in its attempt to DoS the server?

  • Creating dynamic jQuery tooltips for dynamic content

    - by Mel
    I'm using the qTip jQuery plugin to create tooltips for a set of links. Two problems: How do I create a set of tooltips for three dynamically generated links where the content of the tooltip will also be dynamic: a href="books.cfm?bookID=11"Book One a href="books.cfm?bookID=22"Book Two a href="books.cfm?bookID=33"Book Three I would like to create a tooltip for each link. Each tooltip will then load details about each book. Thus I must pass the bookID to the tooltip: $('#catalog a[href]').each(function() { $(this).qtip( { content: { URL: 'cfcs/viewbooks.cfc?method=bookDetails', data: { bookID: <cfoutput>#indexView.bookID#</cfoutput> }, method: 'get' } }); }); Unfortunately the above code is not working correctly. I've gotten it to work when I've used a static 'bookID' instead of a dynamically generated number. Even when it does work (by using a static number for 'bookID', I can't format the data correctly. It comes back as a query result, or a bunch of text strings. Should I send back the results as HTML? Unsure. PS: I am an absolute NOVICE to Javascript and jQuery, so please try not to be as technical. Many thanks!

  • SBS 2011 on different subnet than domain computers

    - by Ravi
    The setup is as follows: SBS 2011 in datacentre on subnet A Domain PCs at another location on subnet B There is a site-to-site VPN. The domain PCs have joined the domain and have the SBS as their primary DNS server. The domain PCs can ping the DC but the problem is that the DC cannot ping any of the remote subnet (subnet B) SBS --Switch -- Router A ------------------- Router B -- Switch -- Domain PCs What is strange is that router A can ping any host on the subnet B. Another host on Subnet A can also ping any host on subnet B. It's only the DC which cannot ping anything to that specific remote subnet B. I did a tracert from the SBS to router B. The packet reaches Router A from the SBS but then it fails. Am I missing some specific settings that needs to be done when SBS is on a different subnet than its member pcs ?

  • How to setup certificate authentication for MS SQL server 2008 R2 ?

    - by Stephane
    Hello, I have to connect an (ADO) application running on a standalone Windows 2003 R2 server to a SQL 2008 R2 database that is a member of the domain. I have setup an SQL authentication account for this and hard-coded the password into the connection string but I wonder if it wouldn't be possible to use certificate-based authentication for this instead. I haven't been able to find any documentation regarding this apparently new functionality of SQL 2008 R2 anywhere. Could someone kindly point me at some good documentation ? Or at least a description of the functionality and whether it could be used in my case or not ? Thank you in advance

  • In C#, are event handler arguments covariant?

    - by Roger Lipscombe
    Maybe covariant's not the word, but if I have a class that raises an event, with (e.g.) FrobbingEventArgs, am I allowed to handle it with a method that takes EventArgs? Here's some code: class Program { static void Main(string[] args) { Frobber frobber = new Frobber(); frobber.Frobbing += FrobberOnFrobbing; frobber.Frob(); } private static void FrobberOnFrobbing(object sender, EventArgs e) { // Do something interesting. Note that the parameter is 'EventArgs'. } } internal class Frobber { public event EventHandler<FrobbingEventArgs> Frobbing; public event EventHandler<FrobbedEventArgs> Frobbed; public void Frob() { OnFrobbing(); // Frob. OnFrobbed(); } private void OnFrobbing() { var handler = Frobbing; if (handler != null) handler(this, new FrobbingEventArgs()); } private void OnFrobbed() { var handler = Frobbed; if (handler != null) handler(this, new FrobbedEventArgs()); } } internal class FrobbedEventArgs : EventArgs { } internal class FrobbingEventArgs : EventArgs { } The reason I ask is that ReSharper seems to have a problem with (what looks like) the equivalent in XAML, and I'm wondering if it's a bug in ReSharper, or a mistake in my understanding of C#.

    - by Nasa
    I have a SQL 2000 server which has databases, under user section of the database object, I have some NT 4.0 groups. These groups were migrated over to Active Directory some time ago using ADMT with SID history. The original source domain groups have since been deleted. The access shown is olddomain\groupname. I don't know why, if they were ntfs permissions they would update automatically to target\groupname. The users in the AD domain still have access to the database as they are a member of the migrated group (Target\groupname). I was wondering 1) Why does the old group (source\groupname) show up as it doesn't exist anymore. But access is still granted to the target group? 2) Is there any easy way to update the group name from source\groupname to target\groupname? Thanks for any help.

  • How to properly close a UDT server in Netty 4

    - by Steffen
    I'm trying to close my UDT server (Netty 4.0.5.Final) with shutDownGracefully() and reopen it on the same port. Unfortunately, I always get the socket exception below although it waits until the future has completed. I also added the socket option SO_REUSEADDR. What is the proper way to do this? Exception in thread "main" com.barchart.udt.ExceptionUDT: UDT Error : 5011 : another socket is already listening on the same UDP port : listen0:listen [id: 0x323d3939] at com.barchart.udt.SocketUDT.listen0(Native Method) at com.barchart.udt.SocketUDT.listen(SocketUDT.java:1136) at com.barchart.udt.net.NetServerSocketUDT.bind(NetServerSocketUDT.java:66) at io.netty.channel.udt.nio.NioUdtAcceptorChannel.doBind(NioUdtAcceptorChannel.java:71) at io.netty.channel.AbstractChannel$AbstractUnsafe.bind(AbstractChannel.java:471) at io.netty.channel.DefaultChannelPipeline$HeadHandler.bind(DefaultChannelPipeline.java:1006) at io.netty.channel.DefaultChannelHandlerContext.invokeBind(DefaultChannelHandlerContext.java:504) at io.netty.channel.DefaultChannelHandlerContext.bind(DefaultChannelHandlerContext.java:487) at io.netty.channel.ChannelDuplexHandler.bind(ChannelDuplexHandler.java:38) at io.netty.handler.logging.LoggingHandler.bind(LoggingHandler.java:254) at io.netty.channel.DefaultChannelHandlerContext.invokeBind(DefaultChannelHandlerContext.java:504) at io.netty.channel.DefaultChannelHandlerContext.bind(DefaultChannelHandlerContext.java:487) at io.netty.channel.DefaultChannelPipeline.bind(DefaultChannelPipeline.java:848) at io.netty.channel.AbstractChannel.bind(AbstractChannel.java:193) at io.netty.bootstrap.AbstractBootstrap$2.run(AbstractBootstrap.java:321) at io.netty.util.concurrent.SingleThreadEventExecutor.runAllTasks(SingleThreadEventExecutor.java:354) at io.netty.channel.nio.NioEventLoop.run(NioEventLoop.java:366) at io.netty.util.concurrent.SingleThreadEventExecutor$2.run(SingleThreadEventExecutor.java:101) at java.lang.Thread.run(Thread.java:724) A small test program demonstration the problem: public class MsgEchoServer { public static class MsgEchoServerHandler extends ChannelInboundHandlerAdapter { } public void run() throws Exception { final ThreadFactory acceptFactory = new UtilThreadFactory("accept"); final ThreadFactory connectFactory = new UtilThreadFactory("connect"); final NioEventLoopGroup acceptGroup = new NioEventLoopGroup(1, acceptFactory, NioUdtProvider.MESSAGE_PROVIDER); final NioEventLoopGroup connectGroup = new NioEventLoopGroup(1, connectFactory, NioUdtProvider.MESSAGE_PROVIDER); try { final ServerBootstrap boot = new ServerBootstrap(); boot.group(acceptGroup, connectGroup) .channelFactory(NioUdtProvider.MESSAGE_ACCEPTOR) .option(ChannelOption.SO_BACKLOG, 10) .option(ChannelOption.SO_REUSEADDR, true) .handler(new LoggingHandler(LogLevel.INFO)) .childHandler(new ChannelInitializer<UdtChannel>() { @Override public void initChannel(final UdtChannel ch) throws Exception { ch.pipeline().addLast(new MsgEchoServerHandler()); } }); final ChannelFuture future = boot.bind(1234).sync(); } finally { acceptGroup.shutdownGracefully().syncUninterruptibly(); connectGroup.shutdownGracefully().syncUninterruptibly(); } new MsgEchoServer().run(); } public static void main(final String[] args) throws Exception { new MsgEchoServer().run(); } }

  • Entity Framework - refresh objects from database

    - by Nebo
    I'm having trouble with refreshing objects in my database. I have an two PC's and two applications. On the first PC, there's an application which communicates with my database and adds some data to Measurements table. On my other PC, there's an application which retrives the latest Measurement under a timer, so it should retrive measurements added by the application on my first PC too. The problem is it doesn't. On my application start, it caches all the data from database and never get new data added. I use Refresh() method which works well when I change any of the cached data, but it doesn't refresh newly added data. Here is my method which should update the data: public static Entities myEntities = new Entities(); public static Measurement GetLastMeasurement(int conditionId) { myEntities.Refresh(RefreshMode.StoreWins, myEntities.Measurements); return (from measurement in myEntities.Measurements where measurement.ConditionId == conditionId select measurement).OrderByDescending(cd => cd.Timestamp).First(); } P.S. Applications have different connection strings in app.config (different accounts for the same DB).
