• NullPointerException when showing JFileChooser

  - by Geo

  I show a JFileChooser with this snippet: public File getDestination() { JFileChooser chooser = new JFileChooser(); chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY); int option = chooser.showSaveDialog(null); if(option == JFileChooser.APPROVE_OPTION) { return chooser.getSelectedFile().getAbsolutePath(); } return new File("."); } Usually, the first time it's showed, it displays & works correctly. The second time, it will always throw this exception: Exception in thread "Basic L&F File Loading Thread" java.lang.NullPointerException at sun.awt.shell.Win32ShellFolder2.pidlsEqual(Unknown Source) at sun.awt.shell.Win32ShellFolder2.equals(Unknown Source) at sun.awt.shell.Win32ShellFolderManager2.isFileSystemRoot(Unknown Source) at sun.awt.shell.ShellFolder.isFileSystemRoot(Unknown Source) at javax.swing.filechooser.FileSystemView.isFileSystemRoot(Unknown Source) at javax.swing.filechooser.WindowsFileSystemView.isTraversable(Unknown Source) at javax.swing.JFileChooser.isTraversable(Unknown Source) at javax.swing.plaf.basic.BasicDirectoryModel$LoadFilesThread.run0(Unknown Source) at javax.swing.plaf.basic.BasicDirectoryModel$LoadFilesThread.run(Unknown Source) Java -version says: java version "1.6.0_20" Java(TM) SE Runtime Environment (build 1.6.0_20-b02) Java HotSpot(TM) Client VM (build 16.3-b01, mixed mode, sharing) And the thread I found here says I should downgrade the Java version. Should I follow their advice, or is there something I could have done wrong?

• Set UIImageView Size?

  - by Tronic

  hi, i have following problem: i generate subviews UIView in an UIScrollView including UIImageViews. NSArray *bilder = [[NSArray alloc] initWithObjects:@"lol.jpg", @"lol2.jpg", nil]; NSArray *added = [[NSMutableArray alloc] init]; UIImageView *tmpView; for (NSString *name in bilder) { UIImage *image = [UIImage imageNamed:name]; tmpView = [[UIImageView alloc] initWithImage:image]; tmpView.contentMode = UIViewContentModeScaleAspectFit; tmpView.frame = CGRectMake(0, 0, 300, 300); [added addObject:tmpView]; [tmpView release]; } CGSize framy = mainFrame.frame.size; NSUInteger x = 0; for (UIView *view in added) { [mainFrame addSubview:view]; view.frame = CGRectMake(framy.height * x++, 0, framy.height, framy.width); } mainFrame.scrollEnabled = YES; mainFrame.pagingEnabled = YES; mainFrame.contentSize = CGSizeMake(framy.height * [added count], framy.width); mainFrame.backgroundColor = [UIColor blackColor]; i get image file names out of an array. now i want to resize the imageview to a specific size, but it won't work. any advice? thanks + regards

• Entity Framework with MySQL - Timeout Expired while Generating Model

  - by Nathan Taylor

  I've constructed a database in MySQL and I am attempting to map it out with Entity Framework, but I start running into "GenerateSSDLException"s whenever I try to add more than about 20 tables to the EF context. An exception of type 'Microsoft.Data.Entity.Design.VisualStudio.ModelWizard.Engine.ModelBuilderEngine+GenerateSSDLException' occurred while attempting to update from the database. The exception message is: 'An error occurred while executing the command definition. See the inner exception for details.' Fatal error encountered during command execution. Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. There's nothing special about the affected tables, and it's never the same table(s), it's just that after a certain (unspecific) number of tables have been added, the context can no longer be updated without the "Timeout expired" error. Sometimes it's only one table left over, and sometimes it's three; results are pretty unpredictable. Furthermore, the variance in the number of tables which can be added before the error indicates to me that perhaps the problem lies in the size of the query being generated to update the context which includes both the existing table definitions, and also the new tables that are being added to it. Essentially, the SQL query is getting too large and it's failing to execute for some reason. If I generate the model with EdmGen2 it works without any errors, but the generated EDMX file cannot be updated within Visual Studio without producing the aforementioned exception. In all likelihood the source of this problem lies in the tool within Visual Studio given that EdmGen2 works fine, but I'm hoping that perhaps others could offer some advice on how to approach this very unique issue, because it seems like I'm not the only person experiencing it. One suggestion a colleague offered was maintaining two separate EBMX files with some table crossover, but that seems like a pretty ugly fix in my opinion. I suppose this is what I get for trying to use "new technology". :(

• EXT-js PropertyGrid best practices to achieve an update ?

  - by Tom

  Hello, I am using EXT-js for a project, usually everything is pretty straight forward with EXT-js, but with the propertyGrid, I am not sure. I'd like some advice about this piece of code. First the store to populate the property grid, on the load event: var configStore = new Ext.data.JsonStore({ // store config autoLoad:true, url: url.remote, baseParams : {xaction : 'read'}, storeId: 'configStore', // reader config idProperty: 'id_config', root: 'config', totalProperty: 'totalcount', fields: [{ name: 'id_config' }, { name: 'email_admin' } , { name: 'default_from_addr' } , { name: 'default_from_name' } , { name: 'default_smtp' } ],listeners: { load: { fn: function(store, records, options){ // get the property grid component var propGrid = Ext.getCmp('propGrid'); // make sure the property grid exists if (propGrid) { // populate the property grid with store data propGrid.setSource(store.getAt(0).data); } } } } }); here is the propertyGrid: var propsGrid = new Ext.grid.PropertyGrid({ renderTo: 'prop-grid', id: 'propGrid', width: 462, autoHeight: true, propertyNames: { tested: 'QA', borderWidth: 'Border Width' }, viewConfig : { forceFit: true, scrollOffset: 2 // the grid will never have scrollbars } }); So far so good, but with the next button, I'll trigger an old school update, and my question : Is that the proper way to update this component ? Or is it better to user an editor ? or something else... for regular grid I use the store methods to do the update, delete,etc... The examples are really scarce on this one! Even in books about ext-js! new Ext.Button({ renderTo: 'button-container', text: 'Update', handler: function(){ var grid = Ext.getCmp("propGrid"); var source = grid.getSource(); var jsonDataStr = null; jsonDataStr = Ext.encode(source); var requestCg = { url : url.update, method : 'post', params : { config : jsonDataStr , xaction : 'update' }, timeout : 120000, callback : function(options, success, response) { alert(success + "\t" + response); } }; Ext.Ajax.request(requestCg); } }); and thanks for reading.

• "Win32 exception occurred releasing IUnknown at..." error using Pylons and WMI

  - by Anders

  Hi all, Im using Pylons in combination with WMI module to do some basic system monitoring of a couple of machines, for POSIX based systems everything is simple - for Windows - not so much. Doing a request to the Pylons server to get current CPU, however it's not working well, or atleast with the WMI module. First i simply did (something) this: c = wmi.WMI() for cpu in c.Win32_Processor(): value = cpu.LoadPercentage However, that gave me an error when accessing this module via Pylons (GET http://ip:port/cpu): raise x_wmi_uninitialised_thread ("WMI returned a syntax error: you're probably running inside a thread without first calling pythoncom.CoInitialize[Ex]") x_wmi_uninitialised_thread: <x_wmi: WMI returned a syntax error: you're probably running inside a thread without first calling pythoncom.CoInitialize[Ex] (no underlying exception)> Looking at http://timgolden.me.uk/python/wmi/tutorial.html, i wrapped the code accordingly to the example under the topic "CoInitialize & CoUninitialize", which makes the code work, but it keeps throwing "Win32 exception occurred releasing IUnknown at..." And then looking at http://mail.python.org/pipermail/python-win32/2007-August/006237.html and the follow up post, trying to follow that - however pythoncom._GetInterfaceCount() is always 20. Im guessing this is someway related to Pylons spawning worker threads and crap like that, however im kinda lost here, advice would be nice. Thanks in advance, Anders

• android.intent.action.SCREEN_ON doesn't work as a receiver intent filter

  - by Jim Blackler

  I'm trying to get a BroadcastReceiver invoked when the screen is turned on. In my AndroidManifest.xml I have specified : <receiver android:name="IntentReceiver"> <intent-filter> <action android:name="android.intent.action.SCREEN_ON"></action> </intent-filter> </receiver> However it seems the receiver is never invoked (breakpoints don't fire, log statements ignored). I've swapped out SCREEN_ON for BOOT_COMPLETED for a test, and this does get invoked. This is in a 1.6 (SDK level 4) project. A Google Code Search revealed this, I downloaded the project and synced it, converted it to work with latest tools, but it too is not able to intercept that event. http://www.google.com/codesearch/p?hl=en#_8L9bayv7qE/trunk/phxandroid-intent-query/AndroidManifest.xml&q=android.intent.action.SCREEN_ON Is this perhaps no longer supported? Previously I have been able to intercept this event successfully with a call to Context.registerReceiver() like so registerReceiver(new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { // ... } }, new IntentFilter(Intent.ACTION_SCREEN_ON)); However this was performed by a long-living Service. Following sage advice from CommonsWare I have elected to try to remove the long-living Service and use different techniques. But I still need to detect the screen off and on events.

• Using Unit of Work design pattern / NHibernate Sessions in an MVVM WPF

  - by Echiban

  I think I am stuck in the paralysis of analysis. Please help! I currently have a project that Uses NHibernate on SQLite Implements Repository and Unit of Work pattern: http://blogs.hibernatingrhinos.com/nhibernate/archive/2008/04/10/nhibernate-and-the-unit-of-work-pattern.aspx MVVM strategy in a WPF app Unit of Work implementation in my case supports one NHibernate session at a time. I thought at the time that this makes sense; it hides inner workings of NHibernate session from ViewModel. Now, according to Oren Eini (Ayende): http://msdn.microsoft.com/en-us/magazine/ee819139.aspx He convinces the audience that NHibernate sessions should be created / disposed when the view associated with the presenter / viewmodel is disposed. He presents issues why you don't want one session per windows app, nor do you want a session to be created / disposed per transaction. This unfortunately poses a problem because my UI can easily have 10+ view/viewmodels present in an app. He is presenting using a MVP strategy, but does his advice translate to MVVM? Does this mean that I should scrap the unit of work and have viewmodel create NHibernate sessions directly? Should a WPF app only have one working session at a time? If that is true, when should I create / dispose a NHibernate session? And I still haven't considered how NHibernate Stateless sessions fit into all this! My brain is going to explode. Please help!

• XmlSerializer Deserialize failures

  - by smvlad

  I have wsdl from third party server. Method that i'm interested in returns XmlNode. My thought was wrap web methods and use XmlSerializer to return strongly typed objects. Returned xml looks like this (i removed soap headers): <Response xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ResponseExt" xmlns="http://www.thirdparty.com/lr/"> <Code>0</Code> <Message>SUCCESS</Message> <SessionId>session_token</SessionId> </Response> Looked simple. Created a class: [XmlRoot("Response")] public class MyClass { public string Code {get; set;} public string Message {get; set;} public string SessionId {get; set;} } Processing time: //XmlNode node = xml from above XmlSerializer serializer = new XmlSerializer(typeof(MyClass)); XmlNodeReader reader = new XmlNodeReader(node); Myclass myclass = serializer.Deserialize(reader) as MyClass Last line is where it blows up with inner exception message: The specified type was not recognized: name='ResponseExt', namespace='http://www.thirdparty.com/lr/', at . I can't figure out how to make Serializer happy and what exactly these two mean xsi:type="ResponseExt" xmlns="http://www.thirdparty.com/lr/ As always any advice and pointer are appreciated

• Forcing UIInterfaceOrientation changes on iPhone

  - by Andiih

  I'm strugging with getting an iPhone application which requires just about every push or pop in the Nav Controller Stack to change orientation. Basically the first view is portrait, the second landscape the third portrait again (Yes I know this is less than ideal, but that's the design and I've got to implement it). I've been through various advice on here.... http://stackoverflow.com/questions/995723/how-do-i-detect-a-rotation-on-the-iphone-without-the-device-autorotating http://stackoverflow.com/questions/1824682/force-portrait-orientation-on-pushing-new-view-to-uinavigationviewcontroller http://stackoverflow.com/questions/181780/is-there-a-documented-way-to-set-the-iphone-orientation But without total success. Setting to link against 3.1.2 my reading of the linked articles above seems to indicate that if my portrait view pushes a view with - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Return YES for supported orientations return ((interfaceOrientation == UIInterfaceOrientationLandscapeRight) ); } Then then that view should appear rotated to landscape. What happens is it appears in its "broken" portrait form, then rotates correctly as the device is turned. If I pop the controller back to my portrait view (which has an appropriate shouldAutoRotate...) then that remains in broken landscape view until the device is returned to portrait orientation. I've also tried removing all the shouldautorotate messages, and instead forcing rotation by transforming the view. This kind of works, and I've figured out that by moving the status bar (which is actually hidden in my application) [UIApplication sharedApplication].statusBarOrientation = UIInterfaceOrientationLandscapeRight; the keyboard will appear with the correct orientation when desired. The problem with this approach is that the status bar transform is weird and ugly when you don't have a status bar - a shadow looms over the page with each change. So. What am I missing. 1) Am I wrong in thinking that in 3.1.2 (or possibly earlier) shouldAutorotateToInterfaceOrientation should provide the desired orientation simply by pushing controllers ? 2) Is there another way of getting keyboards to appear in the correct orientation. 3) Are the undocumented API calls the way to go (please no!)

• jquery sortable scroll problem

  - by Sam Vloeberghs

  Hi I'm having problems using the sortable function of jQ:uery UI. The scroll doesn't seem to work.. If the second list ( lists are created on the table rows in a tbody and each tbody is connect ) isn't visible I want it to be possible to scroll towards it for dropping my table row. This is my HTML set up: <ul> <li> <ul> <li> <table class="treeleerling"> <tbody class="oder0"> <tr class="suborder0"> </tr> <tr class="sub1order"> </tr> </tbody> </table> </li> </ul> </li> <li> <ul> <li> <table class="treeleerling"> <tbody class="oder1"> <tr class="suborder0"> </tr> <tr class="suborder1"> </tr> </tbody> </table> </li> </ul> </li> </ul> And jQuery code $(document).ready(function() { $("#left tbody").sortable({ connectWith : '#left tbody', scroll : true, scrollSensitivity: 40, }); }); The sorting works fine, but the scrolling doesnt.. I'm doing something wrong or what? Plz help and advice.. Thx in advance!

• Vaadin table hide columns and container customization

  - by Alex

  Hello I am testing a project, using Vaadin and Hibernate. I am trying to use the HbnContainer class to show data into table. The problem is that I do not want to show all the properties of the two classes in the table. For example: @Entity @Table(name="users") class User { @Id @GeneratedValue(strategy=GenerationType.AUTO) private Long id; private String name; @ManyToOne(cascade=CascadeType.PERSIST) private UserRole role; //getters and setters } and a second class: @Entity @Table(name="user_roles") class UserRole { @Id @GeneratedValue(strategy=GenerationType.AUTO) private Long id; private String name; //getters and setters } Next, I retrieve my data using the HbnContainer, and connect it to the table: HbnContainer container = new HbnContainer(User.class, app); table.setContainerDataSource(container); The Table will only display the columns from User, and for the "role" it will put the role id instead. How can I hide that column, and replace it with the UserRole.name ? I managed to use a ColumnGenerator() to get the string value in the table, for the UserRole - but I couldn't remove the previous column, with the numerical value. What am I missing? Or, what is the best way to "customize" your data, before displaying a table (if i want to show data in a table from more than one object type.. what do I do?) If I can't find a simple solution soon, I think I will just build the tables "by hand".. So, any advice on this matter? Thank you, Alex

• A simple augmented reality application in C#

  - by Ian

  Hi All, I would like to start a personal project that will give me a lot of new concept to learn and understand. After some thought, I figured that an Augmented Reality related project will be the most beneficial for me because of the following reasons: I haven't tried interfacing a program with a live video/camera feed I haven't done any "image processing" project I haven't done any "graphics rendering" ever With that said, you can assume that I will totally suck at AR. So I'm here to ask for some advice regarding the best way to go through this. st milestone project that I am thinking of is to take a cheap webcam and read some Data Matrix using C#. nd milestone project will render some text-overlay on the feed when presented with a certain Data Matrix. rd milestone project will actually render some 3D shapes. I've searched all-around and found some nice yet advanced materials for AR: http://sites.google.com/site/augmentedrealitytestingsite/ http://soldeveloper.com/ http://www.mperfect.net/wpfAugReal/ So I came here to ask the following: Do you think my milestone is reasonable given my "deficiencies"? In order to start Milestone 1, can you give some materials that I can study? I prefer online materials. Thanks!

• SQL Server Management Studio – tips for improving the TSQL coding process

  - by kristof

  I used to work in a place where a common practice was to use Pair Programming. I remember how many small things we could learn from each other when working together on the code. Picking up new shortcuts, code snippets etc. with time significantly improved our efficiency of writing code. Since I started working with SQL Server I have been left on my own. The best habits I would normally pick from working together with other people which I cannot do now. So here is the question: What are you tips on efficiently writing TSQL code using SQL Server Management Studio? Please keep the tips to 2 – 3 things/shortcuts that you think improve you speed of coding Please stay within the scope of TSQL and SQL Server Management Studio 2005/2008 If the feature is specific to the version of Management Studio please indicate: e.g. “Works with SQL Server 2008 only" Thanks EDIT: I am afraid that I could have been misunderstood by some of you. I am not looking for tips for writing efficient TSQL code but rather for advice on how to efficiently use Management Studio to speed up the coding process itself. The type of answers that I am looking for are: use of templates, keyboard-shortcuts, use of IntelliSense plugins etc. Basically those little things that make the coding experience a bit more efficient and pleasant. Thanks again

• Creating a Sharepoint Development Environment from an Existing Production Environment

  - by Starky

  I have very little experience using Sharepoint but a good amount using Visual Studio 2008, SQL Server 2005, Windows Server 2003 and IIS6. I need to create a development environment for a SharePoint 2007 system that will be used internally. The system is already deployed over two servers - one of the servers simply holds the database and everything else is on the other server. We are also using WSS 3.0. I have created a Virtual Machine with all the required software including a clean installation of SharePoint Server 2007 and I wish to use this single Virtual Machine as the development environment. Right now there are no custom assemblies being used on the production server as far as I am aware. There are 3 websites, one over port 80 for user accesss, one over a custom port for central administration, and one over another custom port. Not sure what the last one is for but my blank instance of Sharepoint on my Virtual Machine also has something similar. I attempted to use the STSADM tool to backup and restore these 3 sites from my production environment to my development environment and while the operations completed succesfully, the central administration site in my development environment acted strangely and I could not access port 80 - I did not seem to have correct credentials for it. I suspected that it would not have been so simple so could I please have advice on how to create my development environment so that I can use it to deploy updates to the production one.

• Injecting Mockito mocks into a Spring bean

  - by teabot

  I would like to inject a Mockito mock object into a Spring (3+) bean for the purposes of unit testing with JUnit. My bean dependencies are currently injected by using the @Autowired annotation on private member fields. I have considered using ReflectionTestUtils.setField but the bean instance that I wish to inject is actually a proxy and hence does not declare the private member fields of the target class. I do not wish to create a public setter to the dependency as I will then be modifying my interface purely for the purposes of testing. I have followed some advice given by the Spring community but the mock does not get created and the auto-wiring fails: <bean id="dao" class="org.mockito.Mockito" factory-method="mock"> <constructor-arg value="com.package.Dao" /> </bean> The error I currently encounter is as follows: ... Caused by: org...NoSuchBeanDefinitionException: No matching bean of type [com.package.Dao] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: { @org...Autowired(required=true), @org...Qualifier(value=dao) } at org...DefaultListableBeanFactory.raiseNoSuchBeanDefinitionException(D...y.java:901) at org...DefaultListableBeanFactory.doResolveDependency(D...y.java:770) If I set the constructor-arg value to something invalid no error occurs when starting the application context.

• how to embed pure as3 bitmap assets with flex4 (worked with flex3)

  - by jedierikb

  In Flex3, I could compile pure as3 code and use "embed" tags to load in images. This was done by Flex making a BitmapAsset class. I can still do this in Flex4. However, there was a trick to fakeout flex3 and use my own mx.core.BitmapAsset class to remove some of the extraneous stuff Flex's BitmapAsset brings in with it. This is described here: http://www.ultrashock.com/forums/flex/embed-flex-assets-without-using-flex-123405.html Unfortunately, I cannot get these tricks to work with Flex4 and get smaller file sizes. I end up with the error "VerifyError: Error #1014: Class mx.core::BitmapAsset could not be found." This error leads me to this forum, and a solution as described there: http://tech.groups.yahoo.com/group/flexcoders/message/148762 Following this advice, I add -static-link-runtime-shared-libraries=true, and my swf loads without an error... but this means I am loading in the pieces of the flex framework I wanted to omit (and the file size says so too). Is there a better way to fake out flex4 when it comes to using Embed?

• Programming activities for high school kids who have no idea what CS or programming is

  - by pointdxt

  I work at a small high school that's in a very high poverty area. There are only a handful of seniors that are thinking about applying to be an engineer of some sort in college and only 1 kid that applied for Computer Science (he has a couple acceptances so far!). He's been talking to me a lot as I majored in Computer Science as well and he is very excited about it. Unfortunately, our school doesn't have a Computer Science course of any kind so he asks me a lot of stuff. I want to help him out since he's really excited about majoring in CS but I don't know where to begin. I could say put Linux on a computer, go online and go research stuff like I did but this kid needs some direction and he doesn't even know what Linux is let alone have a free computer around for that sort of thing. He doesn't know much about CS but is keenly interested in having a computer do all sorts of things but I don't know how to help him in a meaningful way. Any advice? I'm not a teacher at the school so I'm not a great educator, I do IT at the school.

• How To Create Your Own x86 Operating System for Modern PC Computers

  - by mudge

  I'd like to create a new operating system for x86 PC computers. I'd like it to be 64-bit but possibly run as 32-bit as well. I have these kinds of questions: What kinds of things do you start working on first? Knowing where to start in writing your own operating system seems to me to be a tricky subject, so I am interested in your input. Generally how to go about making your own 32-bit/64-bit operating system, or good resources that mention useful information about going about writing your own operating system for x86 computers. I don't care how old sources are as long as they are still relevant and useful to what I am doing. I know that I will want it to have kernel drivers that access peripheral hardware directly. Where should I look for advice and documentation for programming and understanding the interface to peripheral hardware the operating system will communicate with? I will need to understand how the operating system will receive input and interact with keyboards, mice, computer monitors, hard drives, USB, etc. etc. This is probably the area I know least about. I have the Intel instruction set manuals and have been getting more familiar with assembly programming, so the CPU side of things is what I know the most about. At this point I'm thinking that I'd like to implement the Linux system calls within my operating system so that programs that run on Linux can run on my operating system. I want my operating system to use the ELF binary format. I wonder what obstacles I have to overcome to achieve this Linux compatibility. Are the main things implementing the system calls that Linux provides, and using the ELF format? What else? I am also interested in people's thoughts about why it might not be a good idea to make your own operating system, and why it is a good idea to make your own operating system. Thank you for any input.

• load jquery function from a href onclick

  - by QuBaR

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

• determine parity of a bit representation of a number in MIPS

  - by Hristo

  Is there some instruction in MIPS that will determine the parity of a certain bit representation? I know to determine whether a "number" has an even parity or an odd parity is to XOR the individual bits of the binary representation together, but that seems computationally-intensive for a set of MIPS instructions... and I need to do this as quick as possible. Also, the number I'm working in is represented in Grey Code... just to throw that in there. So is there some pseudo-instruction in MIPS to determine the parity of a "number" or do I have to do it by hand? If there is no MIPS instruction, which it seems very unlikely to be, any advice on how to do it by hand? Thanks, Hristo follow-up: I found a optimization, but my implementation isn't working. unsigned int v; // 32-bit word v ^= v >> 1; v ^= v >> 2; v = (v & 0x11111111U) * 0x11111111U; return (v >> 28) & 1;

• "Best" language /architecture for browser-based app with ODBC and sockets? (subjective)

  - by mawg

  Sorry to ask a subjective question, but I would welcome some advice. I am an experienced programmer of embedded s/w, but haven't done much network programming, although I have done a fair bit of hobbyist PHP. Anyway, I have to develop what is probably a fairly general type of app, as shown in this crude diagram --------------------------------------------------------------------------------- | Browser / user interface Takes input from user form and writes data to d/b. | | Also gets data and updates browser contents when when d/b contents are changed | | because of info received over TCP/IP. | |________________________________________________________________________________| | ODBC | |_______________________________________________________________________________| | database | |_______________________________________________________________________________| | ODBC | |_______________________________________________________________________________| | Socket (TCP/IP) | | Send data out when d/b is updated from browser. | | Also, update d/b when data are received over TCP/IP. | |_______________________________________________________________________________| As I say, I imagine this to be a fairly typical architecture? Am I right? Then client is insisting on MSIE - unless I can show compelling technical reasons for FireFox or other then it will have to be MSIE (are there any compelling technical reasons?). So, with MIE (almost) a given, I had though to use PHP, since I know it, but the client seems awfully keen on Java (which ought to be OK since I am conversant with C++) it woudl seem to make sense to use the same language for the "upper" interface between the web pages (which that app generates) and the d/b, and for the "lower" interface between the d/b and the socket. (a single language means a single set of tools since text approach, etc) So, the (probably highly subjective) question is "which language shoudl I choose". As I say, the client is keen on Java. Any compelling reason why not? Is it generally a good choice for the sort of thing described here? Any other hints & tips gratefully appreciated (and up-voted): URLs, books, tool chain suggestions, etc, etc

• Accessing the Atlassian Crowd SOAP API with Suds (python SOAP library)

  - by SeanOC

  Has anybody had any recent success with accessing the Crowd SOAP API via the Suds Python library? I've found a few people successfully doing it in the past but Atlassian seems to have changed their WSDL since then to make the existing advice not entirely helpful. Below is the simplest example I've been trying: from suds.client import Client url = 'https://crowd.hugeinc.com/services/SecurityServer?wsdl' client = Client(url) Unfortunately that generates the following error: Traceback (most recent call last): File "<input>", line 1, in <module> File "/Users/soconnor/.virtualenvs/hugeface/lib/python2.6/site-packages/suds/client.py", line 116, in __init__ sd = ServiceDefinition(self.wsdl, s) File "/Users/soconnor/.virtualenvs/hugeface/lib/python2.6/site-packages/suds/servicedefinition.py", line 58, in __init__ self.paramtypes() File "/Users/soconnor/.virtualenvs/hugeface/lib/python2.6/site-packages/suds/servicedefinition.py", line 137, in paramtypes item = (pd[1], pd[1].resolve()) File "/Users/soconnor/.virtualenvs/hugeface/lib/python2.6/site-packages/suds/xsd/sxbasic.py", line 63, in resolve raise TypeNotFound(qref) TypeNotFound: Type not found: '(AuthenticatedToken, http://authentication.integration.crowd.atlassian.com, )' I've tried to both binding and doctors to fix this problem to no avail. Neither approach resulted in any change. Any further recommendations or suggestions would be incredibly helpful.

• Why is my WPF splash screen progress bar out of sync with the execution of the startup steps?

  - by denny_ch

  Hello, I've implemented a simple WPF splash screen window which informs the user about the progress of the application startup. The startup steps are defined this way: var bootSequence = new[] { new {Do = (Action) InitLogging, Message = "Init logging..."}, new {Do = (Action) InitNHibernate, Message = "Init NHibernate..."}, new {Do = (Action) SetupUnityContainer, Message = "Init Unity..."}, new {Do = (Action) UserLogOn, Message = "Logon..."}, new {Do = (Action) PrefetchData, Message = "Caching..."}, }; InitLogging etc. are methods defined elsewhere, which performs some time consuming tasks. The boot sequence gets executed this way: foreach (var step in bootSequence) { _status.Update(step.Message); step.Do(); } _status denotes an instance of my XAML splash screen window containing a progress bar and a label for status information. Its Update() method is defined as follows: public void Update(string status) { int value = ++_updateSteps; Update(status, value); } private void Update(string status, int value) { var dispatcherOperation = Dispatcher.BeginInvoke( DispatcherPriority.Background, (ThreadStart) delegate { lblStatus.Content = status; progressBar.Value = value; }); dispatcherOperation.Wait(); } In the main this works, the steps get executed and the splash screen shows the progress. But I observed that the splash screen for some reasons doesn't update its content for all steps. This is the reason I called the Dispatcher async and wait for its completion. But even this didn't help. Has anyone else experienced this or some similar behaviour and has some advice how to keep the splash screen's update in sync with the execution of the boot sequence steps? I know that the users will unlikely notice this behaviour, since the splash screen is doing something and the application starts after booting is completed. But myself isn't sleeping well, because I don't know why it is not working as expected... Thx for your help, Denny
