• Android Live Wallpaper: waitForCondition(ReallocateCondition)

  - by jstatz

  I've been developing a live wallpaper using GLWallpaperService, and have gotten good results overall. It runs rock-solid in the emulator and looks good. I've dealt with OpenGL many times before so have a solid command of how to do things... unfortunately I'm having a hell of a time getting this to actually be stable on the actual hardware. The basic symption occurs when you slide the physical keyboard on a Motorola Droid in and out a few times. This causes the wallpaper to get destroyed/recreated several times in quick succession -- which would be fine, as I have my assets clearing in onDestroy and reloading in onSurfaceChanged. The problem is after a few iterations of this, (four or five, maybe) the calls to onSurfaceChanged completely stop, and i get an endless string of this printed to the log: 04-02 00:53:18.088: WARN/SharedBufferStack(1032): waitForCondition(ReallocateCondition) timed out (identity=337, status=0). CPU may be pegged. trying again. Is there something I should be implementing here aside from the Android-typical onSurfaceCreated/onSurfaceChanged/onSurfaceDestroyed triumvirate? Browsing through the WallpaperService and WallpaperRenderer classes doesn't pop up anything obvious to me.

• Problem creating simple "windows script components" on Windows 7.

  - by Bigtoe

  Hi folks, I'm trying to get a Windows Script Component working on and x64 development machine. Works fine on x32 bit. But can't seem to get it running, I have the same problem with both JScript and VBScript. Here's the most simple wsc component possible. All that it does it pop up "Hello" in a message box. If you save the snippit below to a file called test_lib.wsc, you'll then be able to right click and register it. It's now available as a COM Component. <?xml version="1.0"?> <component> <?component error="true" debug="true"?> <registration description="Test Script Library" progid="TestScript.Lib" version="1.00" classid="{314042ea-1c42-4865-956f-08d56d1f00a8}" > </registration> <public> <method name="Hello"> </method> </public> <script language="VBScript"> <![CDATA[ Option Explicit Function Hello() MsgBox("Hello.") End Function ]]> </script> </component> Next create the following sample vb-script and save it to a file called test.vbs dim o set o = createobject("TestScript.Lib") o.hello() When I run the test.vbs with cscript or wscript I always get the following. "C:\test.vbs(3, 1) Microsoft VBScript runtime error: ActiveX component can't create object: 'TestScript.Lib'" This works perfectly fine on a 32 bit XP. Anyone got any ideas about what could be wrong? Thanks a bunch Noel.

• Hibernate: "Field 'id' doesn't have a default value"

  - by André Neves

  Hi, all. I'm facing what I think is a simple problem with Hibernate, but can't get over it (Hibernate forums being unreachable certainly doesn't help). I have a simple class I'd like to persist, but keep getting: SEVERE: Field 'id' doesn't have a default value Exception in thread "main" org.hibernate.exception.GenericJDBCException: could not insert: [hibtest.model.Mensagem] at org.hibernate.exception.SQLStateConverter.handledNonSpecificException(SQLStateConverter.java:103) at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:91) [ a bunch more ] Caused by: java.sql.SQLException: Field 'id' doesn't have a default value [ a bunch more ] The relevant code for the persisted class is: package hibtest.model; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.Id; import javax.persistence.Inheritance; import javax.persistence.InheritanceType; @Entity @Inheritance(strategy = InheritanceType.JOINED) public class Mensagem { protected Long id; protected Mensagem() { } @Id @GeneratedValue public Long getId() { return id; } public Mensagem setId(Long id) { this.id = id; return this; } } And the actual running code is just plain: SessionFactory factory = new AnnotationConfiguration() .configure() .buildSessionFactory(); { Session session = factory.openSession(); Transaction tx = session.beginTransaction(); Mensagem msg = new Mensagem("YARR!"); session.save(msg); tx.commit(); session.close(); } I tried some "strategies" within the GeneratedValue annotation but it just doesn't seem to work. Initializing id doesn't help either! (eg Long id = 20L). Could anyone shed some light? EDIT 2: confirmed: messing with@GeneratedValue(strategy = GenerationType.XXX) doesn't solve it SOLVED: recreating the database solved the problem

• Linq-to-sql Compiled Query returns object NOT belonging to submitted DataContext ?

  - by Vladimir Kojic

  Compiled query: public static class Machines { public static readonly Func<OperationalDataContext, short, Machine> QueryMachineById = CompiledQuery.Compile((OperationalDataContext db, short machineID) => db.Machines.Where(m => m.MachineID == machineID).SingleOrDefault() ); public static Machine GetMachineById(IUnitOfWork unitOfWork, short id) { Machine machine; // Old code (working) //var machineRepository = unitOfWork.GetRepository<Machine>(); //machine = machineRepository.Find(m => m.MachineID == id).SingleOrDefault(); // New code (making problems) machine = QueryMachineById(unitOfWork.DataContext, id); return machine; } It looks like compiled query is returning result from another data context [TestMethod] public void GetMachinesTest() { using (var unitOfWork = IoC.Get<IUnitOfWork>()) { // Compile Query var machine = Machines.GetMachineById(unitOfWork, 3); } using (var unitOfWork = IoC.Get<IUnitOfWork>()) { var machineRepository = unitOfWork.GetRepository<Machine>(); // Get From Repository var machineFromRepository = machineRepository.Find(m => m.MachineID == 2).SingleOrDefault(); var machine = Machines.GetMachineById(unitOfWork, 2); VerifyHuskyHostMachine(machineFromRepository, 2, "Machine 2", "222222", "H400RS", "MachineIconB.xaml", false, true, LicenseType.Licensed, InterfaceType.HuskyHostV2, "10.0.97.2:8080", "10.0.97.2", 8080, "4.0"); VerifyHuskyHostMachine(machine, 2, "Machine 2", "222222", "H400RS", "MachineIconB.xaml", false, true, LicenseType.Licensed, InterfaceType.HuskyHostV2, "10.0.97.2:8080", "10.0.97.2", 8080, "4.0"); Assert.AreSame(machineFromRepository, machine); // FAIL } } If I run other (complex) unit tests I'm getting as expected: An attempt has been made to Attach or Add an entity that is not new, perhaps having been loaded from another DataContext. Another Important information is that this test is under TransactionScope!

• Hibernate: how to call a stored function returning a varchar?

  - by Péter Török

  I am trying to call a legacy stored function in an Oracle9i DB from Java using Hibernate. The function is declared like this: create or replace FUNCTION Transferlocation_Fix (mnemonic_code IN VARCHAR2) RETURN VARCHAR2 After several failed tries and extensive googling, I found this thread on the Hibernate forums which suggested a mapping like this: <sql-query name="TransferLocationFix" callable="true"> <return-scalar column="retVal" type="string"/> select Transferlocation_Fix(:mnemonic) as retVal from dual </sql-query> My code to execute it is Query query = session.getNamedQuery("TransferLocationFix"); query.setParameter("mnemonic", "FC3"); String result = (String) query.uniqueResult(); and the resulting log is DEBUG (org.hibernate.jdbc.AbstractBatcher:366) - - about to open PreparedStatement (open PreparedStatements: 0, globally: 0) DEBUG (org.hibernate.SQL:401) - - select Transferlocation_Fix(?) as retVal from dual TRACE (org.hibernate.jdbc.AbstractBatcher:484) - - preparing statement TRACE (org.hibernate.type.StringType:133) - - binding 'FC3' to parameter: 2 TRACE (org.hibernate.type.StringType:133) - - binding 'FC3' to parameter: 2 java.lang.NullPointerException at oracle.jdbc.ttc7.TTCAdapter.newTTCType(TTCAdapter.java:300) at oracle.jdbc.ttc7.TTCAdapter.createNonPlsqlTTCColumnArray(TTCAdapter.java:270) at oracle.jdbc.ttc7.TTCAdapter.createNonPlsqlTTCDataSet(TTCAdapter.java:231) at oracle.jdbc.ttc7.TTC7Protocol.doOall7(TTC7Protocol.java:1924) at oracle.jdbc.ttc7.TTC7Protocol.parseExecuteDescribe(TTC7Protocol.java:850) at oracle.jdbc.driver.OracleStatement.doExecuteQuery(OracleStatement.java:2599) at oracle.jdbc.driver.OracleStatement.doExecuteWithTimeout(OracleStatement.java:2963) at oracle.jdbc.driver.OraclePreparedStatement.executeUpdate(OraclePreparedStatement.java:658) at oracle.jdbc.driver.OraclePreparedStatement.execute(OraclePreparedStatement.java:736) at com.mchange.v2.c3p0.impl.NewProxyCallableStatement.execute(NewProxyCallableStatement.java:3044) at org.hibernate.dialect.Oracle8iDialect.getResultSet(Oracle8iDialect.java:379) at org.hibernate.jdbc.AbstractBatcher.getResultSet(AbstractBatcher.java:193) at org.hibernate.loader.Loader.getResultSet(Loader.java:1784) at org.hibernate.loader.Loader.doQuery(Loader.java:674) at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:236) at org.hibernate.loader.Loader.doList(Loader.java:2220) at org.hibernate.loader.Loader.listIgnoreQueryCache(Loader.java:2104) at org.hibernate.loader.Loader.list(Loader.java:2099) at org.hibernate.loader.custom.CustomLoader.list(CustomLoader.java:289) at org.hibernate.impl.SessionImpl.listCustomQuery(SessionImpl.java:1695) at org.hibernate.impl.AbstractSessionImpl.list(AbstractSessionImpl.java:142) at org.hibernate.impl.SQLQueryImpl.list(SQLQueryImpl.java:152) at org.hibernate.impl.AbstractQueryImpl.uniqueResult(AbstractQueryImpl.java:811) at com.my.project.SomeClass.method(SomeClass.java:202) ...

• Changing font size of legend title in Python pylab rose/polar plot

  - by LaurieW

  I'm trying to change the font size of the title of an existing legend on a rose, or 'polar', plot. Most of the code was written by somebody else, who is away. I've added:- ax.legend(title=legend_title) setp(l.get_title(), fontsize=8) to add the title 'legend_title', which is a variable that the user enters a string for in a a different function that uses this code. The second line of this doesn't return an error but doesn't appear to do anything either. The complete code is below. 'Rose' and 'RoseAxes' are modules/functions written by somebody. Does anyone know of a way to change the legend title font size? I've found some examples for normal plots but can't find any for rose/polar plots. from Rose.RoseAxes import RoseAxes from pylab import figure, title, setp, close, clf from PlotGeneration import color_map_xml fig = figure(1) rect = [0.02, 0.1, 0.8, 0.8] ax = RoseAxes(fig, rect, axisbg='w') fig.add_axes(ax) if cmap == None: (XMLcmap,colors) = color_map_xml.get_cmap('D:/HRW/VET/HrwPyLibs/ColorMapLibrary/paired.xml',255) else: XMLcmap = cmap bqs = kwargs.pop('CTfigname', None) ax.box(Dir, U, bins = rose_binX, units = unit, nsector = nsector, cmap = XMLcmap, lw = 0, **kwargs ) l = ax.legend() ax.legend(title=legend_title) setp(l.get_texts(), fontsize=8) setp(l.get_title(), fontsize=8) Thanks for any help

• Problems compiling peazip on OSX

  - by Yansky

  I'm having some problems with compiling Peazip on OSX (10.6). I emailed the Peazip developer and he said he probably couldn't help me too much as the error seems to be OSX specific and he doesn't have access to an OSX machine any more. The compiler I'm using is Lazarus as the source is in Pascal. The actual compile process seems to go ok, but when I run the peazip.app program launcher, I get the following error: http://img.photobucket.com/albums/v215/thegooddale/Screen-shot-2010-05-22-at-71907-PM.png Here is the app launcher that the compile made: http://forboden.com/coding/peazip.app.zip - you can use an unzip program to look at the files inside (i.e. unzip it twice). I also tried just running the peazip unix file executable that was produced after the compile from the terminal and I got this: http://img.photobucket.com/albums/v215/thegooddale/Screen-shot-2010-05-22-at-72148-PM.png Here are the messages from the compile log from Lazarus while compiling Peazip: http://pastebin.com/qK4bdncL (I asked on the Lazarus forums and they said I can just ignore those "ld: warning: unknown stabs type" warnings). Here is the info from the project_peach.compiled file: <?xml version="1.0"?> <CONFIG> <Compiler Value="/usr/local/bin/ppc386" Date="1238949773"/> <Params Value=" -MObjFPC -Sgi -O1 -gl -k-framework -kCarbon -k-framework -kOpenGL -k'-dylib_file' -k'/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib:/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib' -WG -vewnhi -l -Fu/Users/yansky/Desktop/peazip-3.1.src/res/themes/crystalc/ -Fu/Developer/lazarus/components/synedit/units/i386-darwin/ -Fu/Developer/lazarus/ideintf/units/i386-darwin/ -Fu/Developer/lazarus/lcl/units/i386-darwin/ -Fu/Developer/lazarus/lcl/units/i386-darwin/carbon/ -Fu/Developer/lazarus/packager/units/i386-darwin/ -Fu/Users/yansky/Desktop/peazip-3.1.src/ -Fu. -opeazip -dLCL -dLCLcarbon project_peach.lpr"/> </CONFIG> I guess there's little chance that anyone here has experience with Pascal and Lazarus since it's not that popular a language and the compiler is still in beta, but I thought I would post here in the hopes that someone might point me in the right general direction about where/how the peazip.app launcher is breaking.

• Amazon ELB CNAME record not working

  - by BarthQuay

  Hi there, I have set up my EC2 infrastructure behind an ELB instance and by using the ELBs DNS name everything works as expected. Now i wanted to forward a subdomain of my main project domain to the ELBs DNS Name with a CNAME entry. I did this about 12 hours ago and it doesnt seem to work, and i dont know why. The subdomain just cant be resolved. This is the DNS entry which was processed from my DNS provider without errors yesterday: @ IN A 111.111.111.111 localhost IN A 127.0.0.1 mail IN A 111.111.111.111 www IN A 111.111.111.111 ftp IN CNAME www beta IN CNAME myelbnamehere.eu-west-1.elb.amazonaws.com imap IN CNAME www loopback IN CNAME localhost pop IN CNAME www relay IN CNAME www smtp IN CNAME www @ IN MX 10 mail Using nslookup, all the subdomains and main domain gets looked up correctly, but beta.domain.com doesnt. I get "** server can't find beta.domain.com: NXDOMAIN" What am i doing wrong ? Do i need to wait longer ? When i use the ELB DNS name directly everything works as expected. When i do an NSlookup on my providers DNS Server, the CNAME gets resolved, but it looks like any other DNS server cant find the subdomain thanks in advance

• Virtual Earth (Bing) Pin "moves" when zoom level changes

  - by Ali

  Hi guys, Created a Virtual Earth (Bing) map to show a simple pin at a particular point. Everything works right now - the pin shows up, the title and description pop up on hover. The map is initially fully zoomed into the pin, but the STRANGE problem is that when I zoom out it moves slightly lower on the map. So if I started with the pin pointing somewhere in Toronto, if I zoom out enough the pin ends up i the middle of Lake Ontario! If I pan the map, the pin correctly stays in its proper location. When I zoom back in, it moves slightly up until it's back to its original correct position! I've looked around for a solution for a while, but I can't understand it at all. Please help!! Thanks a lot! import with javascript: http://ecn.dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=6.2 $(window).ready(function(){ GetMap(); }); map = new VEMap('birdEye'); map.SetCredentials("hash key from Bing website"); map.LoadMap(new VELatLong(43.640144 ,-79.392593), 1 , VEMapStyle.BirdseyeHybrid, false, VEMapMode.Mode2D, true, null); var pin = new VEShape(VEShapeType.Pushpin, new VELatLong(43.640144 ,-79.392593)); pin.SetTitle("Goes to Title of the Pushpin"); pin.SetDescription("Goes as Description."); map.AddShape(pin);

• DynamicJasper font encoding problem

  - by user266956

  Hello All, I'm new to DynamicJasper, I think it's a great project but for a few days I cannot run simple example which will display polish fonts properly. Details sections is generated without any problems automatically displaying polish letters like 'c z z a' etc. where title and column headers contain strange letters instead. I was trying to do the following, but it doesn't work: FastReportBuilder drb = new FastReportBuilder(); Font font = new Font(25, "SansSerif", "Helvetica", Font.PDF_ENCODING_CP1257_Baltic, true); Style titleStyle = new StyleBuilder(false).setFont(font).build(); DynamicReport dr = drb.addColumn("State", "state", String.class.getName(),30) .addColumn("Branch", "branch", String.class.getName(),30) .addColumn("Product Line", "productLine", String.class.getName(),50) .addGroups(2) .setTitle("November 2008 Zrebie aczc!") .setTitleStyle(titleStyle) .setSubtitle("This report was generated at " + new Date()) .setPrintBackgroundOnOddRows(true) .setUseFullPageWidth(true) .build(); JRDataSource ds = new JRBeanCollectionDataSource(this.simples); JasperPrint jp = DynamicJasperHelper.generateJasperPrint(dr, new ClassicLayoutManager(), ds); JasperViewer.viewReport(jp); //finally display the report report Any help would be highly appreciated as dynamicjasper forums seems to be dead and constantly spammed. Thanks in advance! Kris

• Cannot find interface declaration for 'UIResponder'

  - by lfe-eo

  Hi all, I am running into this issue when trying to compile code for an iPhone app that I inherited from a previous developer. I've poked around on a couple forums and it seems like the culprit may be a circular #import somewhere. First - Is there any easy way to find if this is the case/find what files the loop is in? Second - Its definitely possible this isn't the problem. This is the full error (truncated file paths so its easier to view here): In file included from [...]/Frameworks/UIKit.framework/Headers/UIView.h:9, from [...]/Frameworks/UIKit.framework/Headers/UIActivityIndicatorView.h:8, from [...]/Frameworks/UIKit.framework/Headers/UIKit.h:11, from /Users/wbs/Documents/EINetIPhone/EINetIPhone_Prefix.pch:13: [...]/Frameworks/UIKit.framework/Headers/UIResponder.h:15: error: expected ')' before 'UIResponder' [...]/Frameworks/UIKit.framework/Headers/UIResponder.h:17: error: expected '{' before '-' token [...]/Frameworks/UIKit.framework/Headers/UIResponder.h:42: warning: '@end' must appear in an @implementation context [...]/Frameworks/UIKit.framework/Headers/UIResponder.h:51: error: expected ':' before ';' token [...]/Frameworks/UIKit.framework/Headers/UIResponder.h:58: error: cannot find interface declaration for 'UIResponder' As you can see, there are other errors alongside this one. These seem to be simple syntax errors, however, they appear in one of Apple's UIKit files (not my own) so I am seriously doubting that Apple's code is truly producing these errors. I'm stumped as to how to solve this issue. If anyone has any ideas of things I could try or ways/places I could get more info on the problem, I'd really appreciate it. I'm very new to Obj-C and iPhone coding.

• wp_get_archives(cat=id) <-- Any way to specifiy cat id in archives?

  - by Matrym

  Does anyone know how to specify an INCLUDE ONLY category using wp_get_archives? I would like to specify a category but then list results by month. I've tried kwebble's plugin to no avail. I've also found the following on WP forums, but it appears to only exclude categories. Perhaps it can be modified to do include? Even given that, I'm not sure how I would call it... Thanks in advance! add_filter( 'getarchives_where', 'customarchives_where' ); add_filter( 'getarchives_join', 'customarchives_join' ); function customarchives_join( $x ) { global $wpdb; return $x . " INNER JOIN $wpdb->term_relationships ON ($wpdb->posts.ID = $wpdb->term_relationships.object_id) INNER JOIN $wpdb->term_taxonomy ON ($wpdb->term_relationships.term_taxonomy_id = $wpdb->term_taxonomy.term_taxonomy_id)"; } function customarchives_where( $x ) { global $wpdb; $exclude = '1'; // category id to exclude return $x . " AND $wpdb->term_taxonomy.taxonomy = 'category' AND $wpdb->term_taxonomy.term_id NOT IN ($exclude)";

• Bing maps silverlight control pushpin scaling problems.

  - by Rares Musina

  Baiscally my problem is that i've adapted a piece of code found here http://social.msdn.microsoft.com/Forums/en-US/vemapcontroldev/thread/62e70670-f306-4bb7-8684-549979af91c1 which does exactly what I want it to do, that is scale some pushpin images according to the map's zoom level. The only problem is that I've adapted this code to run with the bing maps silverlight control (not virtual earth like in the original example) and now the images scale correclty, but they are repositioned and only reach the desired position when my zoom level is maximum. Any idea why? Help will be greatly appreciated :) Modified code below: var layer = new MapLayer(); map.AddChild(layer); //Sydney layer.AddChild(new Pin { ImageSource = new BitmapImage(new Uri("pin.png", UriKind.Relative)), MapInstance = map }, new Location(-33.86643, 151.2062), PositionMethod.Center); becomes something like layer.AddChild(new Pin { ImageSource = new BitmapImage(new Uri("pin.png", UriKind.Relative)), MapInstance = map }, new Location(-33.92485, 18.43883), PositionOrigin.BottomCenter); I am assuming it has something to do with a different way in which bing maps anchors its UIelements. Details on that are also very userful. Thank you!

• Comparing objects with IDispatch to get main frame only (BHO)

  - by shaimagz

  I don't know if anyone familiar with BHO (Browser Helper Object), but an expert in c++ can help me too. In my BHO I want to run the OnDocumentComplete() function only on the main frame - the first container and not all the Iframes inside the current page. (an alternative is to put some code only when this is the main frame). I can't find how to track when is it the main frame that being populated. After searching in google I found out that each frame has "IDispatch* pDisp", and I have to compare it with a pointer to the first one. This is the main function: STDMETHODIMP Browsarity::SetSite(IUnknown* pUnkSite) { if (pUnkSite != NULL) { // Cache the pointer to IWebBrowser2. HRESULT hr = pUnkSite->QueryInterface(IID_IWebBrowser2, (void **)&m_spWebBrowser); if (SUCCEEDED(hr)) { // Register to sink events from DWebBrowserEvents2. hr = DispEventAdvise(m_spWebBrowser); if (SUCCEEDED(hr)) { m_fAdvised = TRUE; } } } else { // Unregister event sink. if (m_fAdvised) { DispEventUnadvise(m_spWebBrowser); m_fAdvised = FALSE; } // Release cached pointers and other resources here. m_spWebBrowser.Release(); } // Call base class implementation. return IObjectWithSiteImpl<Browsarity>::SetSite(pUnkSite); } This is where I want to be aware whether its the main window(frame) or not: void STDMETHODCALLTYPE Browsarity::OnDocumentComplete(IDispatch *pDisp, VARIANT *pvarURL) { // as you can see, this function get the IDispatch *pDisp which is unique to every frame. //some code } I asked this question on Microsoft forum and I got an answer without explaining how to actually implement that: http://social.msdn.microsoft.com/Forums/en-US/ieextensiondevelopment/thread/7c433bfa-30d7-42db-980a-70e62640184c

• maintaining a large list in python

  - by Oren

  I need to maintain a large list of python pickleable objects that will quickly execute the following algorithm: The list will have 4 pointers and can: Read\Write each of the 4 pointed nodes Insert new nodes before the pointed nodes Increase a pointer by 1 Pop nodes from the beginning of the list (without overlapping the pointers) Add nodes at the end of the list The list can be very large (300-400 MB), so it shouldnt be contained in the RAM. The nodes are small (100-200 bytes) but can contain various types of data. The most efficient way it can be done, in my opinion, is to implement some paging-mechanism. On the harddrive there will be some database of a linked-list of pages where in every moment up to 5 of them are loaded in the memory. On insertion, if some max-page-size was reached, the page will be splitted to 2 small pages, and on pointer increment, if a pointer is increased beyond its loaded page, the following page will be loaded instead. This is a good solution, but I don't have the time to write it, especially if I want to make it generic and implement all the python-list features. Using a SQL tables is not good either, since I'll need to implement a complex index-key mechanism. I tried ZODB and zc.blist, which implement a BTree based list that can be stored in a ZODB database file, but I don't know how to configure it so the above features will run in reasonable time. I don't need all the multi-threading\transactioning features. No one else will touch the database-file except for my single-thread program. Can anyone explain me how to configure the ZODB\zc.blist so the above features will run fast, or show me a different large-list implementation?

• Using inotify-tools and ruby to push uploads to Cloud Files

  - by Christian

  Hi Guys, I wrote a few scripts to monitor an uploads directory for changes, then capture the file uploaded/changed and push it to cloud files using a ruby script. This all works well 95% of the time, the only exception is that occasionally, ruby fails with a 'file does not exist' exception. I am assuming that the ruby 'push' script is being called before the file is 100% in its new location, so the script is being called a little prematurely. I tried adding a little function to my script to check if the file exists, if it doesn't, sleep 5 then try again, but this seems to snowball and eventually dies. I then just added a sleep 2 to all calls, but it hasn't helped as I now get the 'file does not exist' error again. #!/bin/sh function checkExists { if [ ! -e "$1" ] then sleep 5 checkExists $1 fi } inotifywait -mr --timefmt '%d/%m/%y-%H:%M' --format '%T %w %f' -e modify,moved_to,create,delete /home/skylines/html/forums/uploads | while read date dir file; do cloudpath=${dir:20}${file} localpath=${dir}${file} #checkExists $localpath sleep 2 ruby /home/cbiggins/bin/pushToCloud.rb skylinesaustralia.com $cloudpath $localpath echo "${date} ruby /home/cbiggins/bin/pushToCloud.rb skylinesaustralia.com $cloudpath $localpath" >> /var/log/pushToCloud.log done I am looking for any suggestions to help me make this 100% stable (eventually, I'll serve the uploaded files from Cloud FIles, so I need to make sure its perfect) Thanks in advance!

• SugarCRM SOAP set_relationship between Contacts and Prospect lists bug

  - by AntonioCS

  Hey! I am trying to create a relationship between a Prospect List (target list) and a Contact. I create a new contact and get the id of a prospect list all using classes I created which are just wrappers for the soap api calls sugar provides. But the code boils down to this soap call: $this->_sugarsoap->client->__soapCall('set_relationship', array($this->getSessionid(),$relationship)); $this-getSessionid() Is the session Id and $relationship is an array which holds this: array 0 => string 'ProspectLists' (length=13) 1 => string '180ab1f5-cf7e-d386-50f8-4c18a790e016' (length=36) 2 => string 'Contacts' (length=8) 3 => string '76323942-8cbb-3224-f18a-4c19efa80a1b' (length=36) After I try this I always get this error: (I do a var_dump of the returned values of the soap call) object(stdClass)[5] public 'number' => string '20' (length=2) public 'name' => string 'Module Does Not Exist' (length=21) public 'description' => string 'This module is not available on this server' (length=43) This seems like a sugarcrm bug because I do have the contacts module and also the prospect lists module. I know this for a fact because I add a contact via the soap call and also retrieve the id of a prospect list via the soap call. I found this thread in the sugar forums and I did try the code given there but I still got the same error. Anyone have a solution for this? I really need to associate a contact to a prospect list (target list) via a soap call. I am using SugarCRM 5.5.0 (I also tried with sugarcrm 5.5.2 and got the same error) on ubuntu server using mysql. Thanks!

• How do I add a button to my navigationController's right side after pushing another view controller

  - by bobobobo

  So, immediately after pushing a view controller to my tableView, // Override to support row selection in the table view. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // Navigation logic may go here -- // for example, create and push another view controller. AnotherViewController *anotherViewController = [[AnotherViewController alloc] initWithNibName:@"AnotherView" bundle:nil]; [self.navigationController pushViewController:anotherViewController animated:YES]; Ok, so that makes another view slide on, and you can go back to the previous view ("pop" the current view) by clicking the button that automatically appears in the top left corner of the navigation bar now. Ok, so SAY I want to populate the RIGHT SIDE of the navigation bar with a DONE button, like in the "Notes" app that comes with the iPhone. How would I do that? I tried code like this: UIBarButtonItem * doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector( doneFunc ) ]; self.navigationController.navigationItem.rightBarButtonItem = doneButton ; // not it.. [doneButton release] ; doneFunc is defined, and everything, just the button never appears on the right side..

• Clear form field after select for jQuery UI Autocomplete

  - by jonfhancock

  I'm developing a form, and using jQuery UI Autocomplete. When the user selects an option, I want the selection to pop into a span appended to the parent <p> tag. Then I want the field to clear rather than be populated with the selection. I have the span appearing just fine, but I can't get the field to clear. How do you cancel jQuery UI Autocomplete's default select action? Here is my code: var availableTags = ["cheese", "milk", "dairy", "meat", "vegetables", "fruit", "grains"]; $("[id^=item-tag-]").autocomplete({ source: availableTags, select: function(){ var newTag = $(this).val(); $(this).val(""); $(this).parent().append("<span>" + newTag + "<a href=\"#\">[x]</a> </span>"); } }); Simply doing $(this).val(""); doesn't work. What is maddening is that almost the exact function works fine if I ignore autocomplete, and just take action when the user types a comma as such: $('[id^=item-tag-]').keyup(function(e) { if(e.keyCode == 188) { var newTag = $(this).val().slice(0,-1); $(this).val(''); $(this).parent().append("<span>" + newTag + "<a href=\"#\">[x]</a> </span>"); } }); The real end result is to get autocomplete to work with multiple selections. If anybody has any suggestions for that, they would be welcome.

• How do I specify a crossdomain policy file to allow Flash to grab a bitmap from an RTMP (Wowza) vide

  - by Ken Smith

  I'm trying to get a bitmap/snapshot of a Wowza video stream playing on my client, like so: var bitmapData:BitmapData = new BitmapData(view.videoPlayerComponent.width, view.videoPlayerComponent.height); bitmapData.draw(view.videoPlayerComponent); When I do this, I get this error message: SecurityError: Error #2123: Security sandbox violation: BitmapData.draw: http://localhost:51150/Resources/WRemoteWebCam.swf cannot access rtmp://localhost/videochat/smithkl42._default/. No policy files granted access. I presume the error comes from not being able to locate the appropriate crossdomain.xml file. I'm not quite sure where it's looking for it, and a wireshark sniff was inconclusive, so I've tried placing one in each of the following places: http://localhost/crossdomain.xml http://localhost:1935/crossdomain.xml http://localhost:51150/crossdomain.xml I can retrieve the file successfully from each of those three locations. (I'm pretty sure that the last one wouldn't have any effect, since it's just the location of the web site which hosts the page that hosts the .swf file, but on the off chance...) These are the contents of the file that it's grabbing in each instance: <cross-domain-policy> <allow-access-from domain="*" to-ports="*" /> </cross-domain-policy> And it's still throwing that same error message. I've also followed the instructions on the Wowza forums, to turn on StreamVideoSampleAccess in the [install]\conf[appname]\Application.xml, with no joy: <Client> <IdleFrequency>-1</IdleFrequency> <Access> <StreamReadAccess>*</StreamReadAccess> <StreamWriteAccess>*</StreamWriteAccess> <StreamAudioSampleAccess>*</StreamAudioSampleAccess> <StreamVideoSampleAccess>*</StreamVideoSampleAccess> <SharedObjectReadAccess>*</SharedObjectReadAccess> <SharedObjectWriteAccess>*</SharedObjectWriteAccess> </Access> </Client> Any thoughts?

• Compiling a DLL which includes Ogre3D gives an assertion error when used

  - by samaursa

  Hi, I have a framework that I am building and is being compiled into a static library to be used by other projects. The library works perfectly without issues. The problem is that the link time is very long for the projects that use the library so I thought I will make a DLL project of the same framework. I started with baby steps and created an MFC DLL project through visual studio. The project has the following header: /// -------------------------------------------- #ifndef OGRECORE_H #define OGRECORE_H #ifdef OGREFW_EXPORT #define OGREFW_DLL __declspec(dllexport) #else #define OGREFW_DLL __declspec(dllimport) #endif class OgreRoot; namespace OgreFW { class OGREFW_DLL OgreCore// : public OIS::KeyListener, public OIS::MouseListener { public: OgreCore(); ~OgreCore(); }; }; #endif // OGRECORE_H and this is the source #include "stdafx.h" #include "OgreCore.h" //#include "Ogre.h" //#include "OgreRoot.h" //#include "OgreRenderWindow.h" //#include "OgreLog.h" //#include "OgreLogManager.h" //#include "OgreOverlay.h" //#include "OgreViewport.h" //#include "OgreRenderWindow.h" //#include "OgreFrameListener.h" //#include "OgreWindowEventUtilities.h" //#include "OgreSceneNode.h" //#include "OgreEntity.h" //#include "OgreManualObject.h" //#include "OgreMeshManager.h" //#include "OgreConfigFile.h" //#include "OgreOverlayContainer.h" //#include "OgreOverlayManager.h" namespace OgreFW { OGREFW_DLL OgreCore::OgreCore() { } // ------------------------ OGREFW_DLL OgreCore::~OgreCore() { } } As you can see I have commented out Ogre includes. When a project uses the compiled DLL and constructs this (OgreCore) class, it works perfectly fine. As soon as uncomment one of the Ogre includes and compile the DLL again, the project that uses the DLL now gives an assertion error. The full details can be found here in the Ogre forum post. I posted the question there first but since its not really an Ogre specific question I thought I will try here as well. The link to the Ogre post is: http://www.ogre3d.org/forums/viewtopic.php?f=2&t=58403 Thank you in advance

• How to create mobile substrate plugins on XCode?

  - by prathumca

  Hi Everyone, I just wanna create a MS plugin to hook SpringBoard. I'm following "gojohnnyboi" tutorial from here "http://www.ipodtouchfans.com/forums/showthread.php?t=103558". To create a dylib on XCode, I'm following "SkylarEC" tutorial. I mix these two great tutorials and finally got succeed by getting a dylib. But when I placed the dylib in the /Library/MobileSubstrate/DynamicLibraries/ nothing is happened (no alert was shown). By evaluating, I found that, this dylib doesn't have any starting point when it was loaded into the memory. So I mentioned a starting point by declaring a constructor in the .mm file like, __ attribute__((constructor)) static void init() { Class _$SBAppIcon = objc_getClass("SBApplicationIcon"); MSHookMessage($SBAppIcon, @selector(launch), (IMP) &_$ExampleHook_AppIcon_Launch, "_OriginalMethodPrefix"); } But when I'm trying to compile this, I'm getting an error like, Undefined symbols: "_MSHookMessage", referenced from: init() in ExampleHook.o ld: symbol(s) not found collect2: ld returned 1 exit status. Does anyone has idea how to solve this? It would be great and more helpful if anyone share the detailed tutorial/instructions to create a dylib on XCode. P.S I placed all the libsubstrate.dylib and substrate.h files in the corresponding location. And the locations are, libsubstrate.dylib : /Developer/Platforms/iPhoneOS.platform/Developer/usr/lib/ substrate.h : /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.0.sdk/usr/include and my base SDK is 3.0.

• UIAlertViewDelegate method didDismissWithButtonIndex gets called while the phone is sleeping/locked.

  - by Rob

  I have a UIAlertView who's didDismissWithButtonIndex delegate method calls pops the view controller (same class, it's the alertview delegate and the viewcontroller) to return the user to the previous screen. The issue is that when you lock the phone before the [alert show]; is called, something is calling didDismissWithButtonIndex while the phone is locked. Since the response to that is to pop the view controller, which releases and deallocs it, I crash on the callback. What is causing this phantom button press? Seems like a framework bug, but I hate jumping to that conclusion. I'm definitely not hitting the button, because I hit a breakpoint in my code right before it's displayed. Then I lock the phone. Then I continue. I see it do the show, return to the event loop, and then, while the phone is still locked, hit my breakpoint in didDismissWithButtonIndex. There are a few internet/forum postings about similar spurious delegate calls, but no concrete answers. This is on the simulator, and the device, both OS 2.2 and OS 3.0. I'm assuming I'm missing something, but what? Update: Yeah, I created a simple project with just two view controllers, where when the 2nd view controller displays it creates the alert, and shows it. Then I NSLog in the delegate method, and when the phone is locked, it fires once while locked, and then again when it's unlocked and the button is clicked...2 log messages. But when not locked, there's only one. I guess I'll open an issue, but it seems awfully obvious to have survived this long without anyone complaining. :-) I'm going to try and work around it by making an isActive flag value when the willResignActive/didBecomeActive notifications arrive, and if the app isn't active skipping the delegate body. Update I went ahead in July after I posted this and created radar 7097363 for this issue. There's been no response. The workaround in practice works quite well, checking the active status when processing the delegate, and skipping the action if the the app is inactive.

• HttpWebRequest: The request was aborted: The request was canceled.

  - by Emeka

  I've been working on developing a middle man application of sorts, which uploads text to a CMS backend using HTTP post requests for a series of dates (usually 7 at a time). I am using HttpWebRequest to accomplish this. It seems to work fine for the first date, but when it starts the second date I get the System.Net.WebException: The request was aborted: The request was canceled. I've searched around and found the following big clues: http://social.msdn.microsoft.com/Forums/en-US/netfxnetcom/thread/0d0afe40-c62a-4089-9d8b-fb4d206434dc http://www.jaxidian.org/update/2007/05/05/8 http://arnosoftwaredev.blogspot.com/2006/09/net-20-httpwebrequestkeepalive-and.html And they haven't been too helpful. I've tried overloading the GetWebReuqest but that doesn't make sense because I don't make any use of that function. Here is my code: http://pastebin.org/115268 I get the error on line 245 after it has run successfully at least once. I'd appreciate any help I can get as this is the last step in a project I've been working on for sometime. This is my first C#/VS project so I'm open to any tips but I would like to focus on getting this problem solved first. THanks!

• Ext-GWT / GXT (Not So) Simple Layout Issue?

  - by Xandel

  Hi all, I have posted this question on the Ext-GWT forums, I am just hoping that someone here might have an answer for me! I am struggling to do something I initially thought was simple but am beginning to believe is impossible... I have got a "layout template" of sorts - simply consisting of a few GWT DockLayoutPanel's within each other and finally ending in LayoutPanels. GWT's LayoutPanel is designed to size the widget (or Composite) that's added to it to its full size and does so perfectly with pure GWT widgets. The idea of my "layout template" is that I don't know the EXACT height and width of the very inner LayoutPanel's because I may set certain panels sizes (of the outer DockLayoutPanels) differently when instantiating this template. All I would like is to add a Grid component to one of the inner most LayoutPanels and have it size itself (height AND width) to fit as normal GWT widgets do (works perfectly with a GWT Label for instance). I am VERY new to GXT (as in I started using it earlier today) and I do realize that GXT builds its Components differently to the way GWT builds its Widgets on the DOM. Is there anyway to achieve the desired result? I have tried adding the grid to a ContentPanel with a Layout of FitLayout, I have tried AnchorLayout, I have tried adding the grid directly... Nothing seems to work... Any advice or even a push in the right direction would be greatly appreciated! Thanks in advance! Xandel
