• Coredump in Multithreading Application in RHEL-5

  - by Chinnu

  I am working on multi-threading application it is dumping frequently.I could not able to analyaze the core.The core is showing like this Core was generated by 'thread-process'. Program terminated with signal 6, Aborted. #0 0x00000038f4e30045 in raise () from /lib64/libc.so.6 (gdb) where #0 0x00000038f4e30045 in raise () from /lib64/libc.so.6 #1 0x00000038f4e31ae0 in abort () from /lib64/libc.so.6 #2 0x00000038f4e681bb in __libc_message () from /lib64/libc.so.6 #3 0x00000038f4e72b96 in free () from /lib64/libc.so.6 #4 0x000000000046a137 in std::string::substr () #5 0x000000000042c549 in std::operator<< <char, std::char_traits<char>, std::allocator<char> > () #6 0x000000000042cc1d in std::operator<< <char, std::char_traits<char>, std::allocator<char> > () #7 0x000000000046b069 in std::string::substr () #8 0x000000000046c866 in std::string::substr () #9 0x0000000000431062 in std::operator<< <char, std::char_traits<char>, std::allocator<char> > () #10 0x00000038f5a062e7 in start_thread () from /lib64/libpthread.so.0 #11 0x00000038f4ece3bd in clone () from /lib64/libc.so.6

• Setting database-agnostic default column timestamp using Hibernate

  - by unsquared

  I'm working on a java project full of Hibernate (3.3.1) mapping files that have the following sort of declaration for most domain objects. <property name="dateCreated" generated="insert"> <column name="date_created" default="getdate()" /> </property> The problem here is that getdate() is an MSSQL specific function, and when I'm using something like H2 to test subsections of the project, H2 screams that getdate() isn't a recognized function. It's own timestamping function is current_timestamp(). I'd like to be able to keep working with H2 for testing, and wanted to know whether there was a way of telling Hibernate "use this database's own mechanism for retrieving the current timestamp". With H2, I've come up with the following solution. CREATE ALIAS getdate AS $$ java.util.Date now() { return new java.util.Date(); } $$; CALL getdate(); It works, but is obviously H2 specific. I've tried extending H2Dialect and registering the function getdate(), but that doesn't seem to be invoked when Hibernate is creating tables. Is it possible to abstract the idea of a default timestamp away from the specific database engine?

• Unable to connect on socket across different networks.

  - by maleki

  I am having trouble connecting my online application to others across another network. I am able to give them the hostAddress to connect when we are on the same network but when we are doing it across the internet the generated host address doesn't allow a connection, nor does using the ip address gotten from online sites such as whatismyip.com My biggest issue isn't debugging this code, because it works over intra-network but The server doesn't see attempts when we try to move to different networks. Also, the test ip I am using is 2222. InetAddress addr = InetAddress.getLocalHost(); String hostname = addr.getHostName(); System.out.println("Hostname: " + hostname); System.out.println("IP: " + addr.getHostAddress()); I display the host to the server when it is starting if (isClient) { System.out.println("Client Starting.."); clientSocket = new Socket(host, port_number); } else { System.out.println("Server Starting.."); echoServer = new ServerSocket(port_number); clientSocket = echoServer.accept(); System.out.println("Warning, Incoming Game.."); }

• Problem with RVM and gem that has an executable

  - by djhworld

  Hi there, I've recently made the plunge to use RVM on Ubuntu. Everything seems to have gone swimmingly...except for one thing. I'm in the process of developing a gem of mine that has a script placed within its own bin/ directory, all of the gemspec and things were generated by Jeweler. The bin/mygem file contains the following code: - #!/usr/bin/env ruby begin require 'mygem' rescue LoadError require 'rubygems' require 'mygem' end app = MyGem::Application.new app.run That was working fine on the system version of Ruby. Now...recently I've moved to RVM to manage my ruby versions a bit better, except now my gem doesn't appear to be working. Firstly I do this: - rvm 1.9.2 Then I do this: - rvm 1.9.2 gem install mygem Which installs fine, except...when I try to run the command for mygem mygem I just get the following exception: - daniel@daniel-VirtualBox:~$ mygem <internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- mygem (LoadError) from <internal:lib/rubygems/custom_require>:29:in `require' from /home/daniel/.rvm/gems/ruby-1.9.2-p136/gems/mygem-0.1.4/bin/mygem:2:in `<top (required)>' from /home/daniel/.rvm/gems/ruby-1.9.2-p136/bin/mygem:19:in `load' from /home/daniel/.rvm/gems/ruby-1.9.2-p136/bin/mygem:19:in `<main>'mygem NOTE: I have a similar RVM setup on MAC OSX and my gem works fine there so I think this might be something to do with Ubuntu?

• making java SingleFrameApplication to appear second

  - by Karel Bílek

  Sorry if this question will sound too chaotic, feel free to edit it. I have an application made entirely in netbeans, which uses SingleFrameApplication and auto-generated the GUI code, named "MyApp", and FrameView, named "MyView". Now, the MyApp somehow has the main() function, but the MyView has all the graphic elements.. I don't entirely understand how that happens, so used it as black box (it somehow created the window, I didn't have to care why). But now, I need the window to be only a window, opened by another JFrame. I don't know, how to accomplish that. MyApp, which is extending SingleFrameApplication, have these methods: public class MyApp extends SingleFrameApplication { @Override protected void startup() { show(new MyView(this)); } @Override protected void configureWindow(java.awt.Window root) { } public static MyApp getApplication() { return Application.getInstance(MyApp.class); } public static void main(String[] args) { launch(MyApp.class, args); } } MyView has these methods: public class MyView extends FrameView { public MyView(SingleFrameApplication app) { super(app); initComponents(); } private void initComponents() { //all the GUI stuff is somehow defined here } } Now, I have no clue how the two classes work, I just want this window, defined in MyView, to appear after another window, "ordinary" JFrame. How can I call this MyApp/MyView?

• Does JAXWS client make difference between an empty collection and a null collection value as returne

  - by snowflake

  Since JAX-WS rely on JAXB, and since I observed the code that unpack the XML bean in JAX-B Reference Implementation, I guess the difference is not made and that a JAXWS client always return an empty collection, even the webservice result was a null element: public T startPacking(BeanT bean, Accessor<BeanT, T> acc) throws AccessorException { T collection = acc.get(bean); if(collection==null) { collection = ClassFactory.create(implClass); if(!acc.isAdapted()) acc.set(bean,collection); } collection.clear(); return collection; } I agree that for best interoperability service contracts should be non ambiguous and avoid such differences, but it seems that the JAX-WS service I'm invoking (hosted on a Jboss server with Jbossws implementation) is returning as expected either null either empty collection (tested with SoapUI). I used for my test code generated by wsimport. Return element is defined as: @XmlElement(name = "return", nillable = true) protected List<String> _return; I even tested to change the Response class getReturn method from : public List<String> getReturn() { if (_return == null) { _return = new ArrayList<String>(); } return this._return; } to public List<String> getReturn() { return this._return; } but without success. Any helpful information/comment regarding this problem is welcome !

• Using of Templated Helpers in MVC 2.0 : How can use the name of the property that I'm rendering insi

  - by Andrey Tagaew

  Hi. I'm reviewing new features of ASP.NET MVC 2.0. During the review i found really interesting using Templated Helpers. As they described it, the primary reason of using them is to provide common way of how some datatypes should be rendered. Now i want to use this way in my project for DateTime datatype My project was written for the MVC 1.0 so generating of editbox is looking like this: <%= Html.TextBox("BirthDate", Model.BirthDate, new { maxlength = 10, size = 10, @class = "BirthDate-date" })%> <script type="text/javascript"> $(document).ready(function() { $(".BirthDate-date").datepicker({ showOn: 'button', buttonImage: '<%=Url.Content("~/images/i_calendar.gif") %>', buttonImageOnly: true }); }); </script> Now i want to use Template Helper, so i want to have above code once i type next sentence: <%=Html.EditorFor(f=>f.BirthDate) %> According to the manual I create DataTime.ascx partial view inside Shared/EditorTemplates folder. I put there above code and stacked with the problem. How can i pass the name of the property that I'm rendering with template helper? As you can see from my example, i really need it, since I'm using the name of the property to specify data value and parameter name that will be send during the POST requsest. Also, I'm using it to generate class name for JS calendar building. I tried to remove my partial class for template helper and made MVC to generate its default behavior. Here what it generated for me: <input type="text" value="04/29/2010" name="LoanApplicationDays" id="LoanApplicationDays" class="text-box single-line"> As you can see, it used the name of the property for "name" and "id" attributes. This example let me to presume that Template Helper knows about the name of the property. So, there should be some way of how to use it in custom implementation. Thanks for your help!

• How to deserialize MXML with PHP?

  - by Ivan Petrushev

  Hello, I have an array structure that have to be converted to MXML. I know of PEAR XML_Serialize extension but it seems the output format it produces is a bit different. PHP generated XML: <zone columns="3"> <select column="1" /> <select column="4" /> </zone> MXML format: <mx:zone columns="3"> <mx:select column="1" /> <mx:select column="4" /> </mx:zone> Is that "mx:" prefix required for all the tags? If yes, can I make the XML_Serialize put it before each tag (without renaming my data structure fields to "mx:something")? Here are my options for XML_Serialize: $aOptions = array('addDecl' => true, 'indent' => " ", 'rootName' => 'template', 'scalarAsAttributes' => true, 'mode' => 'simplexml');

• why is the <img> alt attribute not always properly displayed

  - by Piero

  So I have this php script that output an html table with data about some files (like filename, filesize, etc...) I have this javascript function that displays the picture when you hover a tag belonging to the class "preview". For example, if a filename is: somePic.jpg, when you hover somePic.jpg in the table, the picture will appear next to your mouse. Now not all these files are pictures, some are .mp3, so of course when you hover them, the javascript cannot display the picture. To deal with this case, I added in the tag (generated by the javascript function), an alt attribute: alt='Preview not available for this type of content.' And here is my problem, sometimes it works, but sometimes it doesn't! Sometimes you start hovering .mp3 links, and the alt attribute is displayed, then you hover a picture, the picture is displayed, then you hover an .mp3 again, and the alt isn't displayed anymore, but the "broken image" image (the little red cross) is displayed instead... Sure I could parse the filenames and detect when it's an mp3 and then deal with the case, but I thought the alt attribute was suppose to achieve this... but it's buggy... Any idea? Does anyone already faced this problem?

• Flex through Flash Builder 4; Connecting to a dynamic XML feed: "The response is not a valid XML or

  - by jtromans

  I am learning how to use Flex with Adobe Flash Builder 4 standalone. I am working my through the Adobe Flash Build 4 Bible by David Gassner. This has led me to create my own micro problems to try and solve. I am trying to connect to a dynamix XML feed created by the following aspx page: generate_xml.aspx When I create the data connection through the Data/Service panel, I can pick between XML and HTTP. I figured because the generate_xml.aspx has to generate the XML file first, I should use the HTTP service as opposed to the XML. The HTTP service offers GET, which seems to be the kinda thing I want. However, I am really struggling to do this. I keep getting: "The response is not a valid XML or a JSON string" The actual STATIC generated XML file that is created by this page works perfectly when I save it and manually connect with the XML service. Therefore I know my XML code is properly formatted and contains no other HTML of JavaScript. I figure my problem occurs because the page itself is .aspx, but I cannot work out how to successfully ask Flex to request the output of this page, rather than the page itself.

• Make seems to think a prerequisite is an intermediate file, removes it

  - by James

  For starters, this exercise in GNU make was admittedly just that: an exercise rather than a practicality, since a simple bash script would have sufficed. However, it brought up interesting behavior I don't quite understand. I've written a seemingly simple Makefile to handle generation of SSL key/cert pairs as necessary for MySQL. My goal was for make <name> to result in <name>-key.pem, <name>-cert.pem, and any other necessary files (specifically, the CA pair if any of it is missing or needs updating, which leads into another interesting follow-up exercise of handling reverse deps to reissue any certs that had been signed by a missing/updated CA cert). After executing all rules as expected, make seems to be too aggressive at identifying intermediate files for removal; it removes a file I thought would be "safe" since it should have been generated as a prereq to the main rule I'm invoking. (Humbly translated, I likely have misinterpreted make's documented behavior to suit my expectation, but don't understand how. ;-) Edited (thanks, Chris!) Adding %-cert.pem to .PRECIOUS does, of course, prevent the deletion. (I had been using the wrong syntax.) Makefile: OPENSSL = /usr/bin/openssl # Corrected, thanks Chris! .PHONY: clean default: ca clean: rm -I *.pem %: %-key.pem %-cert.pem @# Placeholder (to make this implicit create a rule and not cancel one) Makefile: @# Prevent the catch-all from matching Makefile ca-cert.pem: ca-key.pem $(OPENSSL) req -new -x509 -nodes -days 1000 -key ca-key.pem $@ %-key.pem: $(OPENSSL) genrsa 2048 $@ %-cert.pem: %-csr.pem ca-cert.pem ca-key.pem $(OPENSSL) x509 -req -in $ $@ Output: $ make host1 /usr/bin/openssl genrsa 2048 ca-key.pem /usr/bin/openssl req -new -x509 -nodes -days 1000 -key ca-key.pem ca-cert.pem /usr/bin/openssl genrsa 2048 host1-key.pem /usr/bin/openssl req -new -days 1000 -nodes -key host1-key.pem host1-csr.pem /usr/bin/openssl x509 -req -in host1-csr.pem -days 1000 -CA ca-cert.pem -CAkey ca-key.pem -set_serial 01 host1-cert.pem rm host1-csr.pem host1-cert.pem This is driving me crazy, and I'll happily try any suggestions and post results. If I'm just totally noobing out on this one, feel free to jibe away. You can't possibly hurt my feelings. :)

• How to get the "real" colors when exporting a GDI drawing to bmp

  - by Rodrigo

  Hi guys I'm developing a ASP.Net web handler that returns images making a in-memory System.Windows.Forms.Control and then exports the rendered control as a bitmap compressed to PNG, using the method DrawToBitmap(). The classes are fully working by now, except for a problem with the color assignment. By example, this is a Gauge generated by the web handler. The colors assigned to the inner parts of the gauge are red (#FF0000), yellow (#FFFF00) and green (#00FF00) but I only get a dully version of each color (#CB100F for red, #CCB70D for yellow and #04D50D for green). The background is a bmp file containing the color gradient. The color loss happens whether the background is a gradient as the sample, a black canvas, a white canvas, a transparent canvas, even when there is not a background set. With black background With transparent background With a white background Without a background set With pixel format in Format32bppArgb I've tried multiple bitmap color deeps, output formats, compression level, etc. but none of them seems to work. Any ideas? This is a excerpt of the source code: Bitmap bmp = new Bitmap(w, h, System.Drawing.Imaging.PixelFormat.Format32bppPArgb); Image bgimage = (Image) HttpContext.GetGlobalResourceObject("GraphicResources", "GaugeBackgroundImage"); Canvas control_canvas = new Canvas(); .... //the routine that makes the gauge .... control_canvas.DrawToBitmap(bmp, new Rectangle(0, 0, w, h));

• Tricky file parsing. Inconsistent Delimeters

  I need to parse a file with the following format. 0000000 ...ISBN.. ..Author.. ..Title.. ..Edit.. ..Year.. ..Pub.. ..Comments.. NrtlExt Nrtl Next Navg NQoH UrtlExt Urtl Uext Uavg UQoH ABS NEB MBS FOL ABE0001 0-679-73378-7 ABE WOMAN IN THE DUNES (INT'L ED) 1st 64 RANDOM 0.00 13.90 0.00 10.43 0 21.00 10.50 6.44 3.22 2 2.00 0.50 2.00 2.00 ABS The ID and ISBN are not a problem, the title is. There is no set length for these fields, and there are no solid delimiters- the space can be used for most of the file. Another issue is that there is not always an entry in the comments field. When there is, there are spaced within the content. So I can get the first two, and the last fourteen. I need some help figuring out how to parse the middle six fields. This file was generated by an older program that I cannot change. I am using php to parse this file.

• How to elegantly handle ReturnUrl when using UrlRewrite in ASP.NET 2.0 WebForms

  - by Brian Kim

  I have a folder with multiple .aspx pages that I want to restrict access to. I have added web.config to that folder with <deny users="?"/>. The problem is that ReturnUrl is auto-generated with physical path to the .aspx file while I'm using UrlRewrite. Is there a way to manipulate ReturnUrl without doing manual authentication check and redirection? Is there a way to set ReturnUrl from code-behind or from web.config? EDIT: The application is using ASP.NET 2.0 WebForms. I cannot use 3.5 routing. EDIT 2: It seems like 401 status code is never captured. It returns 302 for protected page and redirects to login page with ReturnUrl. It does not return 401 for protected page. Hmm... Interesting... Ref: http://msdn.microsoft.com/en-us/library/aa480476.aspx This makes things harder... I might have to write reverse rewrite mapping rules to regex match ReturnUrl and replace it if it doesn't return 401... If it does return 401 I can either set RawUrl to Response.RedirectLocation or replace ReturnUrl with RawUrl. Anyone else have any other ideas?

• How do I label a group of radio boxes for WCAG / 508 Compliance? Is ASP.NET doing it wrong?

  - by Mark Brittingham

  I am trying to bring an existing web site into greater conformance with WCAG 2.0 Guidelines and am a bit confused over the output emitted by Microsoft (ASP.NET 4.0 although it was the same in 3.5). Suppose you have a question like: "How would you rate your health?" and a set of 5 answers created using an ASP.NET RadioButtonList. I place the question in an asp:Label with an "AssociatedControlID" that matches the ID of the RadioButtonList (e.g. "SelfRatingBox"). Seems pretty easy... Only the output that is generated has an html "label" with a "For" that is equal to the ID of a table that wraps up the RadioButtons. I assumed that this would work with page readers but our 508 compliance guy is saying that the reader isn't associating the label with the radio controls. The WCAG guidelines indicate that you have to use a fieldset around the entire group and a legend to capture the associated text (the question). So what gives? It would be ideal if MS could take my label and the radiobuttonlist and generate the appropriate fieldset and legend tags but it seems pretty clear that to achieve WCAG compliance, I'll have to roll my own. Is this correct or am I missing something?

• Create Folders from text file and place dummy file in them using a CustomAction

• Is there any way to combine transparency and "ajax usability" with HTML templates

  - by Sam

  I'm using HTML_Template_Flexy in PHP but the question should apply to any language or template library. I am outputting a list of relatively complex objects. In the beginning I just iterated over a list of the objects and called a toHtml method on them. When I was about to have my layout designer look over the template I noticed that it was too opaque and that he would have ended up looking through and/or editing many additional php source files to see what really gets generated by the toHtml method. So I extracted most of the HTML strings in the php classes up to the template which made for one clear file where you can see the whole page structure at once. However this causes problems when you want to add an object to the list using javascript. Then I have to keep the old toHtml method and maintain both the main template and the html strings at the same time, so I can output just the HTML for a new object that should be added to the page. So I'm back to the idea of using smaller templates for the objects that make up the page, but I was wondering if there was some easy way of having my cake and eating it too by having one template that shows the whole page but also the mini-templates for smaller objects on the page. Edit: Yes, updating the page is not a problem at all. My concern is with having both maintainability and transparency of the template files. If I have one single template for the whole page, then I must maintain mini-templates of the objects that are shown on the page. If I just have the mini-templates and include them from the higher-level template it becomes more difficult to look at the top-level html and imagine what the end result will look like.

• YUI button onclick get value

I cannot get the value, the alert doesn't fire, but I see no error in FireBug or the error console. alert(button.get('type')); returns push - I would expect checkbox alert(button.get('id')); returns analystbutton1-button

• Memory leak for NSDictionary loaded by plist file

The memory leak is evidenced by Instruments, highlighted the line: [NSDictionary dictionaryWithContentsOfFile:pathOpere] This is the dealloc method: - (void)dealloc { [tipologia release]; [compositore release]; [nomeCompleto release]; [super dealloc];}

• MS Source Server - source stream is apparently not there when viewing with srctool

  - by Tim Peel

  Hi, I have been playing around with the MS Source Server stuff in the MS Debugging Tools install. At present, I am running my code/pdbs through the Subversion indexing command, which is now running as expected. It creates the stream for a given pdb file and writes it to the pdb file. However when I use that DLL and associated pdb in visual studio 2008, it says the source code cannot be retrieved. If I check the pdb against srctool is says none of the source files contained are indexed, which is very strange as the process prior ran fine. If I check the stream that was generated from the svnindex.cmd run for the pdb, srctool says all source files are indexed. Why would there be a difference? I have opened the pdb file in a text editor and I can see the original references to the source files on my machine (also under the srcsrv header name) and the new "injected" source server links to my subversion repository). Should both references still exist in the pdb? I would have expected one to be removed? Either way, visual studio 2008 will not pick up my source references so I am a bit lost as to what to try next. As far as I can tell, I have done everything I should have. Anyone have similar experiences? Many thanks.

• How to avoid chaotic ASP.NET web application deployment?

  - by emzero

  Ok, so here's the thing. I'm developing an existing (it started being an ASP classic app, so you can imagine :P) web application under ASP.NET 4.0 and SQLServer 2005. We are 4 developers using local instances of SQL Server 2005 Express, having the source-code and the Visual Studio database project This webapp has several "universes" (that's how we call it). Every universe has its own database (currently on the same server) but they all share the same schema (tables, sprocs, etc) and the same source/site code. So manually deploying is really annoying, because I have to deploy the source code and then run the sql scripts manually on each database. I know that manual deploying can cause problems, so I'm looking for a way of automating it. We've recently created a Visual Studio Database Project to manage the schema and generate the diff-schema scripts with different targets. I don't have idea how to put the pieces together I would like to: Have a way to make a "sync" deploy to a target server (thanksfully I have full RDC access to the servers so I can install things if required). With "sync" deploy I mean that I don't want to fully deploy the whole application, because it has lots of files and I just want to deploy those new or changed. Generate diff-sql update scripts for every database target and combine it to just 1 script. For this I should have some list of the databases names somewhere. Copy the site files and executing the generated sql script in an easy and automated way. I've read about MSBuild, MS WebDeploy, NAnt, etc. But I don't really know where to start and I really want to get rid of this manual deploy. If there is a better and easier way of doing it than what I enumerated, I'll be pleased to read your option. I know this is not a very specific question but I've googled a lot about it and it seems I cannot figure out how to do it. I've never used any automation tool to deploy. Any help will be really appreciated, Thank you all, Regards

• Display last picture

  - by steve

  Hi I'm inserting an image from the camera (Taking a picture) into the MediaStore.Images.Media datastore. Does anyone know how I can go about displaying the last picture taken? I used Uri image = ContentUris.withAppendedId(externalContentUri, 45); to display an image from the datastore but obviously 45 is not the correct image. I try to pass the information from the previous activity (Camera) to the display activity but I'm assuming due to the photo call back being its own thread the value never gets set. Photo code is as follows Camera.PictureCallback photoCallback = new Camera.PictureCallback() { public void onPictureTaken(byte[] data, Camera camera) { // TODO Auto-generated method stub FileOutputStream fos; try { Bitmap bm = BitmapFactory.decodeByteArray(data, 0, data.length); fileUrl = MediaStore.Images.Media.insertImage(getContentResolver(), bm, "LastTaken", "Picture"); if(fileUrl == null) { Log.d("Still", "Image Insert Failed"); return; } else { picUri = Uri.parse(fileUrl); sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, picUri)); } } catch(Exception e) { Log.d("Picture", "Error Picture: ", e); } camera.startPreview(); } };
