  • WPF data validation is overriding theme on the interface

    - by black sensei
    Hello! Good People I built a WPF application and manage to get the validation working thanks to posts on stackoverflow.The only probblem i'm having is that it's overriding the theme i'm using. example the theme makes the textboxes look like a round rectangle but after setting the binding it look like the default textboxes. here is my code : <Button.Style> <Style TargetType="{x:Type Button}"> <Setter Property="IsEnabled" Value="false" /> <Style.Triggers> <!-- Require the controls to be valid in order to press OK --> <MultiDataTrigger> <MultiDataTrigger.Conditions> <Condition Binding="{Binding ElementName=txtEmail, Path=(Validation.HasError)}" Value="false" /> </MultiDataTrigger.Conditions> <Setter Property="IsEnabled" Value="true" /> </MultiDataTrigger> </Style.Triggers> </Style> </Button.Style> code behind is : //Form loaded event code txtEmail.GetBindingExpression(TextBox.TextProperty).UpdateSource(); I've tried to look into the theme file but i was quickly lost.i thought i could use that file like a web css file.Now i've disabled the data binding because of that.Is there any work around for this? thanks for reading this

  • Opencv application crashes at runtime with error code 0x0000142

    - by Tuan Anh
    I have openCV and minGW installed with codeblock IDE following the instructions found here http://kevinhughes.ca/tutorials/opencv-install-on-windows-with-codeblocks-and-mingw/ i tried the simple image loading program in the article and the build process went fine. but when i tried running the output program, it crashes with the error message "the application was unable to start correctly (0xc0000142). Click OK to close the application." I used Dependency Walker to see if the program failed to load dll module and here's the output screen of Dependency Walker https://www.dropbox.com/s/f9iaftdt8atjwpl/Screenshot%202013-11-05%2022.21.45.png i am not used to DW but as i can see in its output screen, some openCV dll failed to load and the loaded Windows DLL were 64 bit instead of 32 bit (as minGW is 32 bit). I can't figure out why as i already configure the Path environment variable for the bin directory of openCV and the app still can not load the dll modules. And i think that Windows will automatically load the proper 32 bit DLLs when a 32 bit app is run but this situation the app still failed to load. Anyone has ideas?

  • How to get principal name from HTTPRequest in CXF JAX-RS webservice method called from android app.

    - by johnrock
    How can I get the principal name, session and ideally check if the principal is authenticated with the Spring Security context inside a CXF JAX-RS webservice method receiving a call from an Android client? This is the code I am currently working with. I have commented where and what I am trying to get. Android code to call webservice: httpclient.getCredentialsProvider().setCredentials( new AuthScope("192.168.1.101", 80), new UsernamePasswordCredentials("joesmith", "mypasswd")); HttpGet httpget = new HttpGet(WEBSERVICE_URL+"/makePayload"); httpget.setHeader("User-Agent", userAgent); httpget.setHeader("Content-Type", "application/xml"); HttpResponse response; try { response = httpclient.execute(httpget); HttpEntity entity = response.getEntity(); ... parse xml from response } CXF, Spring webservice code: @GET @Path("/getPayload") @Produces("application/XML") public Response makePayload(@Context Request request){ //Get user principal name //Get session? //Get Spring security context? Payload payload = new Payload(); payload.setUsersOnline(new Long(200)); return Response.ok().entity(payload).build(); }

  • Facebook Graph API authentication in canvas app and track session

    - by cdpnet
    Short question is: how can i use graph api oauth redirects mechanism to authenticate user and save retrieved access_token and also use javascript SDK when needed (the problem is javascript SDK will have different access_token when initialized). I have initially setup my facebook iframe canvas app, with single sign on. This works well with graph api, as I am able to use access_token saved by facebook's javascript when it detects sessionchange(user logged in). But, I want to rather not do single sign-on. But, use graph api redirect and force user to send to a permissions dialog. But, if he has already given permissions, I shouldn't redirect user. How to handle this? Another question: I have done graph api redirects for authentication and have retrieved access_token also. But then, what if I want to use javascript call FB.ui to do stream.Publish? I think it will use it's own access_token which is set during FB.init and detecting session. So, I am looking for some path here. How to use graph api for authentication and also use facebook's javascript SDK when needed. P.S. I'm using ASP .NET MVC 2. I have an authentication filter developed, which needs to detect the user's authentication state and redirect.(currently it does this to graph api authorize url)

  • JsonParseException on Valid JSON

    - by user2909602
    I am having an issue calling a RESTful service from my client code. I have written the RESTful service using CXF/Jackson, deployed to localhost, and tested using RESTClient successfully. Below is a snippet of the service code: @POST @Produces("application/json") @Consumes("application/json") @Path("/set/mood") public Response setMood(MoodMeter mm) { this.getMmDAO().insert(mm); return Response.ok().entity(mm).build(); } The model class and dao work successfully and the service itself works fine using RESTClient. However, when I attempt to call this service from Java Script, I get the error below on the server side: Caused by: org.codehaus.jackson.JsonParseException: Unexpected character ('m' (code 109)): expected a valid value (number, String, array, object, 'true', 'false' or 'null') I have copied the client side code below. To make sure it has nothing to do with the JSON data itself, I used a valid JSON string (which works using RESTClient, JSON.parse() method, and JSONLint) in the vars 'json' (string) and 'jsonData' (JSON). Below is the Java Script code: var json = '{"mood_value":8,"mood_comments":"new comments","user_id":5,"point":{"latitude":37.292929,"longitude":38.0323323},"created_dtm":1381546869260}'; var jsonData = JSON.parse(json); $.ajax({ url: 'http://localhost:8080/moodmeter/app/service/set/mood', dataType: 'json', data: jsonData, type: "POST", contentType: "application/json" }); I've seen the JsonParseException a number of times on other threads, but in this case the JSON itself appears to be valid (and tested). Any thoughts are appreciated.

  • Getting a binary file from resource in C#

    - by Jesse Knott
    Hello, I am having a bit of a problem, I am trying to get a PDF as a resource in my application. At this point I have a fillable PDF that I have been able to store as a file next to the binary, but now I am trying to embed the PDF as a resource in the binary. byte[] buffer; try { s = typeof(BattleTracker).Assembly.GetManifestResourceStream("libReports.Resources.DAForm1594.pdf"); buffer = new byte[s.Length]; int read = 0; do { read = s.Read(buffer, read, 32768); } while (read > 0); } catch (Exception e) { throw new Exception("Error: could not import report:", e); } // read existing PDF document PdfReader r = new PdfReader( // optimize memory usage buffer, null ); Every time I run the code I get an error saying "Rebuild trailer not found. Original Error: PDF startxref not found" When I was just opening the file via a path to the static file in my directory it worked fine. I have tried using different encodings UTF-8, UTF-32, UTF-7, ASCII, etc etc.... As a side note I had the same problem with getting a Powerpoint file as a resource, I was finally able to fix that problem by converting the Powerpoint to xml and using that. I have considered doing the same for the PDF but I am referencing elements by field name which does not seem to work with XML PDFs. Can anyone help me out with this? Thanks in advance!

  • Flex 4 vs JavaScript Options (Cappuccino, JQuery, etc.)

    - by user320681
    Rehashing an older post: http://stackoverflow.com/questions/1570070/jquery-vs-flex-choosing-a-platform-for-saas We are preparing to develop an application that is exceptionally dynamic and interactive. It's particularly heavy on the graphics side. We are 85% convinced that Adobe Flash built atop Flex is the right path to take, however Cappuccino is quite nice and seems as though it may be able to nearly fit the bill. The only pause we have right now is portability for the iPhone. With the lack of blessings from Apple we will most certainly have to create a 2nd interface for the iPhone for the site, however... Having two interfaces may not be bad as it will likely have to be custom anyway to take advantage of the differences that it affords. Any further thoughts or reevaluations of points enumerated in the noted article? Further, Flex 4 adds a lot of strength to the position mentioned previously regarding UI development. Fx4 is very nice vs Fx3 and shaves 90% from the development time when coupled with Flash Catalyst, which is not really always fully appropriate, but with some round trip tricks it seems as though it can cut through things rather well... Please do advise and many thanks.

  • Synchronize DataGrid and DataForm in Silverlight 3

    - by SpiralGray
    I've been banging my head against the wall for a couple of days on this and it's time to ask for help. I've got a DataGrid and DataForm on the same UserControl. I'm using an MVVM approach so there is a single ViewModel for the UserControl. That ViewModel has a couple of properties that are relevant to this discussion: public ObservableCollection<VehicleViewModel> Vehicles { get; private set; } public VehicleViewModel SelectedVehicle { get { return selectedVehicle; } private set { selectedVehicle = value; OnPropertyChanged( "SelectedVehicle" ); } } In the XAML I've got the DataGrid and DataForm defined as follows: <data:DataGrid SelectionMode="Single" ItemsSource="{Binding Vehicles}" SelectedItem="{Binding SelectedVehicle, Mode=TwoWay}" AutoGenerateColumns="False" IsReadOnly="True"> <dataFormToolkit:DataForm CurrentItem="{Binding SelectedVehicle}" /> So as the SelectedItem changes on the DataGrid it should push that change back to the ViewModel and when the ViewModel raises the OnPropertyChanged the DataForm should refresh itself with the information for the newly-selected VehicleViewModel. However, the setter for SelectedVehicle is never being called and in the Output window of VS I'm seeing the following error: System.Windows.Data Error: ConvertBack cannot convert value 'xxxx.ViewModel.VehicleViewModel' (type 'xxxx.ViewModel.VehicleViewModel'). BindingExpression: Path='SelectedVehicle' DataItem='xxxx.ViewModel.MainViewModel' (HashCode=31664161); target element is 'System.Windows.Controls.DataGrid' (Name=''); target property is 'SelectedItem' (type 'System.Object').. System.MethodAccessException: xxxx.ViewModel.MainViewModel.set_SelectedVehicle(xxxx.ViewModel.VehicleViewModel) It sounds like it's having a problem converting from a VehicleViewModel to an object (or back again), but I'm confused as to why that would be (or even if I'm on the right track with that assumption). Each row/item in the DataGrid should be a VehicleViewModel (because the ItemsSource is bound to an ObservableCollection of that type), so when the SelectedItem changes it should be dealing with an instance of VehicleViewModel. Any insight would be appreciated.

  • Parsing large delimited files with dynamic number of columns

    - by annelie
    Hi, What would be the best approach to parse a delimited file when the columns are unknown before parsing the file? The file format is Rightmove v3 (.blm), the structure looks like this: #HEADER# Version : 3 EOF : '^' EOR : '~' #DEFINITION# AGENT_REF^ADDRESS_1^POSTCODE1^MEDIA_IMAGE_00~ // can be any number of columns #DATA# agent1^the address^the postcode^an image~ agent2^the address^the postcode^^~ // the records have to have the same number of columns as specified in the definition, however they can be empty etc #END# The files can potentially be very large, the example file I have is 40Mb but they could be several hundred megabytes. Below is the code I had started on before I realised the columns were dynamic, I'm opening a filestream as I read that was the best way to handle large files. I'm not sure my idea of putting every record in a list then processing is any good though, don't know if that will work with such large files. List<string> recordList = new List<string>(); try { using (FileStream fs = new FileStream(path, FileMode.Open, FileAccess.Read)) { StreamReader file = new StreamReader(fs); string line; while ((line = file.ReadLine()) != null) { string[] records = line.Split('~'); foreach (string item in records) { if (item != String.Empty) { recordList.Add(item); } } } } } catch (FileNotFoundException ex) { Console.WriteLine(ex.Message); } foreach (string r in recordList) { Property property = new Property(); string[] fields = r.Split('^'); // can't do this as I don't know which field is the post code property.PostCode = fields[2]; // etc propertyList.Add(property); } Any ideas of how to do this better? It's C# 3.0 and .Net 3.5 if that helps. Thanks, Annelie

  • Can't write the SysWow64 value to registry with vbscript for Screensaver

    - by Valentein
    Scripts, registries, screen-savers, oh my! I'm trying to use a screen-saver on a Windows XP 64 bit machine which uses a .NET app which makes an interop call which relies on some x86 Shockwave Dlls (some Shockwave animation). Everything should be in the %systemroot%\WINNT\SysWOW64 directory. When the timeout for the screensaver occurs, the process should looks like this: Screensaver.scr - .NET app - shockwave animation. During installation I want a vbscript to my screen-saver file to copy the Screensaver.scr to the SysWow64 directory and then set the proper registry key to this file for Windows to launch the screen-saver. The code is something like this: Dim sScreenSaver, tScreenSaver sScreenSaver = "C:\SourceFiles\bin\ScreenSaver.scr" 'screensaver tScreenSaver = "C:\winnt\SysWOW64\" Set WshShell = WScript.CreateObject("WScript.Shell") 'script shell to run objects Set FSO = createobject("scripting.filesystemobject") 'file system object 'copy screensaver FSO.CopyFile sScreenSaver, tScreenSaver, True 'set screen saver Dim p1 p1 = "HKEY_CURRENT_USER\Control Panel\Desktop\" WshShell.RegWrite p1 & "SCRNSAVE.EXE", (tScreenSaver & "ScreenSaver.scr") After installation, I can verify the the Screensaver exists in the correct directory. (It actually seems to be in both the system32 and the sysWOW64 directories---whether that's the install script or something I did post-install I'm in the process of verifying.) However, the registry entry is not correct. In both the 32 and 64 bit regedit I see the HKCU\ControlPanel\Desktop\SCRNSAVE.EX is set to: C:\WINNT\system32\Screensaver.scr This isn't right. The screen-saver won't run from this directory. It only runs from SysWOW64. If I manually edit the registry with regedit to the correct SysWOW64 path everything works fine. Is this a problem with using the script or is this a Windows registry redirection, or filesystem redirection problem? You'd think this would be simple...

  • ocunit testing on iPhone

    - by Magnus Poromaa
    Hi I am trying to get ocunit working in my project from XCode. Since I also need to debug in the unit tests I am using a script that automates the setup (see below). I just include it in the project under resources and change the name to the .ocunit file I want it to run. The problem I get is that it cant find the bundle file and therefore exists with an error. Can anyone who has a clue about XCode and objective-c take a look at it and tell me what is wrong. Also how am I supposed to produce the .ocunit file that I need to run. By setting up a new unit test target for the iPhone and add tests to it or? Hope someone has a clue since I just started ny iPhone development and need to get it up and running quickly Apple Script -- The only customized value we need is the name of the test bundle tell me to activate tell application "Xcode" activate set thisProject to project of active project document tell thisProject set testBundleName to name of active target set unitTestExecutable to make new executable at end of executables set name of unitTestExecutable to testBundleName set path of unitTestExecutable to "/Applications/TextEdit.app" tell unitTestExecutable -- Add a "-SenTest All" argument make new launch argument with properties {active:true, name:"-SenTest All"} -- Add the magic set injectValue to "$(BUILT_PRODUCTS_DIR)/" & testBundleName & ".octest" make new environment variable with properties {active:true, name:"XCInjectBundle", value:injectValue} make new environment variable with properties {active:true, name:"XCInjectBundleInto", value:"/Applications/TextEdit.app/Contents/MacOS/TextEdit"} make new environment variable with properties {active:true, name:"DYLD_INSERT_LIBRARIES", value:"$(DEVELOPER_LIBRARY_DIR)/PrivateFrameworks/DevToolsBundleInjection.framework/DevToolsBundleInjection"} make new environment variable with properties {active:true, name:"DYLD_FALLBACK_FRAMEWORK_PATH", value:"$(DEVELOPER_LIBRARY_DIR)/Frameworks"} end tell end tell end tell Cheers Magnus

  • Different versions of JBoss on the same host

    - by Vladimir Bezugliy
    I have JBoss 4 installed on my PC to directory C:\JBoss4 And environment variable JBOSS_HOME set to this directory: JBOSS_HOME=C:\JBoss4 I need to install JBoss 5.1 on the same PC. I installed it into C:\JBoss51 In order to start JBoss 5.1 on the same host where JBoss 4 was already started, I need to redefine properties jboss.home.dir, jboss.home.url, jboss.service.binding.set: C:\JBoss51\bin\run.sh -Djboss.home.dir=C:/JBoss51 \ -Djboss.home.url=file:/C:/JBoss51 \ -Djboss.service.binding.set=ports-01 But in C:\JBoss51\bin\run.sh I can see following code: … if [ "x$JBOSS_HOME" = "x" ]; then # get the full path (without any relative bits) JBOSS_HOME=`cd $DIRNAME/..; pwd` fi export JBOSS_HOME … runjar="$JBOSS_HOME/bin/run.jar" JBOSS_BOOT_CLASSPATH="$runjar" And this code does not depend either on jboss.home.dir or on jboss.home.dir. So when I start JBoss 5.1 script will use jar files from JBoss 4.3? Is it correct? Should I redefine environment variable JAVA_HOME when I start JBoss 5.1? In this case script will use correct jar files. Or if I redefined properties jboss.home.dir, jboss.home.url then JBoss will not use any variables set in run.sh? How does it works?

  • Sysdeo Tomcat DevLoader - Hot deploy of java class causes whole application to restart

    - by Gala101
    Hi, I am using sysdeo tomcat plugin 3.2.1 with eclipse 3.5.1 (Galileo) and tomcat 5.5.23 on windows XP. I can get tomcat plugin working in eclipse, and have extracted devloader.zip into [tomcat]\server\classes. I have also updated the context and now it has this entry: <Context path="/myapp1" reloadable="true" docBase="F:\Work\eclipse_workspace\myapp1" workDir="F:\Work\eclipse_workspace\myapp1\work" > <Logger className="org.apache.catalina.logger.SystemOutLogger" verbosity="4" timestamp="true"/> <Loader className="org.apache.catalina.loader.DevLoader" reloadable="true" debug="1" useSystemClassLoaderAsParent="false" /> </Context> I have activated devloader (in Project Properties Tomcat Devloader Classpath) and have 'checked' all my classes and jars, I haven't 'checked' commons-loggin.jar jsp-api.jar, servlet-api.jar. So on launching tomcat via the plugin, I can get it running with devloader as shown in eclipse console view [DevLoader] Starting DevLoader [DevLoader] projectdir=F:\Work\eclipse_workspace\myapp1 [DevLoader] added file:/F:/Work/eclipse_workspace/myapp1/WEB-INF/classes/ [DevLoader] added file:/F:/Work/eclipse_workspace/myapp1/WEB-INF/lib/activation.jar However, if I even add a single System.out.println into any java file and save it, the whole application gets reloaded (takes ~80 sec) which is as good as stopping/starting tomcat itself. I've tried adding -Xdebug in JAVA_OPTS in the catalina.bat but no luck :( Can you please guide where I may be doing it wrong.. Please note that I can 'redeploy' the whole application on tomcat but that's not what I need, I am looking to be able to make small changes in java classes 'on-the-fly' while coding/debugging without having to wait for complete app restart. Another annoyance is that restarting tomcat/application causes the session/debug progress to be lost.. Can you please guide me how to go about it. PS: I am not using any ant/maven scripts explicitly, just relying on eclipse to do the build for me (which it does).

  • Trouble binding WPF Menu to ItemsSource

    - by chaiguy
    I would like to avoid having to build a menu manually in XAML or code, by binding to a list of ICommand-derived objects. However, I'm experiencing a bit of a problem where the resulting menu has two levels of menu-items (i.e. each MenuItem is contained in a MenuItem): My guess is that this is happening because WPF is automatically generating a MenuItem for my binding, but the "viewer" I'm using actually already is a MenuItem (it's derived from MenuItem): <ContextMenu x:Name="selectionContextMenu" ItemsSource="{Binding Source={x:Static OrangeNote:Note.MultiCommands}}" ItemContainerStyleSelector="{StaticResource separatorStyleSelector}"> <ContextMenu.ItemTemplate> <DataTemplate> <Viewers:NoteCommandMenuItemViewer CommandParameter="{Binding Source={x:Static OrangeNote:App.Screen}, Path=SelectedNotes}" /> </DataTemplate> </ContextMenu.ItemTemplate> </ContextMenu> (The ItemContainerStyleSelector is from http://bea.stollnitz.com/blog/?p=23, which allows me to have Separator elements inside my bound source.) So, the menu is bound to a collection of ICommands, and each item's CommandParameter is set to the same global target (which happens to be a collection, but that's not important). My question is, is there any way I can bind this such that WPF doesn't automatically wrap each item in a MenuItem?

  • Blackberry read local properties file in project

    - by Dachmt
    Hi, I have a config.properties file at the root of my blackberry project (same place as Blackberry_App_Descriptor.xml file), and I try to access the file to read and write into it. See below my class: public class Configuration { private String file; private String fileName; public Configuration(String pathToFile) { this.fileName = pathToFile; try { // Try to load the file and read it System.out.println("---------- Start to read the file"); file = readFile(fileName); System.out.println("---------- Property file:"); System.out.println(file); } catch (Exception e) { System.out.println("---------- Error reading file"); System.out.println(e.getMessage()); } } /** * Read a file and return it in a String * @param fName * @return */ private String readFile(String fName) { String properties = null; try { System.out.println("---------- Opening the file"); //to actually retrieve the resource prefix the name of the file with a "/" InputStream is = this.getClass().getResourceAsStream(fName); //we now have an input stream. Create a reader and read out //each character in the stream. System.out.println("---------- Input stream"); InputStreamReader isr = new InputStreamReader(is); char c; System.out.println("---------- Append string now"); while ((c = (char)isr.read()) != -1) { properties += c; } } catch (Exception e) { } return properties; } } I call my class constructor like this: Configuration config = new Configuration("/config.properties"); So in my class, "file" should have all the content of the config.properties file, and the fileName should have this value "/config.properties". But the "name" is null because the file cannot be found... I know this is the path of the file which should be different, but I don't know what i can change... The class is in the package com.mycompany.blackberry.utils Thank you!

  • There's a black hole in my server (TcpClient, TcpListener)

    - by Matías
    Hi, I'm trying to build a server that will receive files sent by clients over a network. If the client decides to send one file at a time, there's no problem, I get the file as I expected, but if it tries to send more than one I only get the first one. Here's the server code: I'm using one Thread per connected client public void ProcessClients() { while (IsListening) { ClientHandler clientHandler = new ClientHandler(listener.AcceptTcpClient()); Thread thread = new Thread(new ThreadStart(clientHandler.Process)); thread.Start(); } } The following code is part of ClientHandler class public void Process() { while (client.Connected) { using (MemoryStream memStream = new MemoryStream()) { int read; while ((read = client.GetStream().Read(buffer, 0, buffer.Length)) > 0) { memStream.Write(buffer, 0, read); } if (memStream.Length > 0) { Packet receivedPacket = (Packet)Tools.Deserialize(memStream.ToArray()); File.WriteAllBytes(Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory), Guid.NewGuid() + receivedPacket.Filename), receivedPacket.Content); } } } } On the first iteration I get the first file sent, but after it I don't get anything. I've tried using a Thread.Sleep(1000) at the end of every iteration without any luck. On the other side I have this code (for clients) . . client.Connect(); foreach (var oneFilename in fileList) client.Upload(oneFilename); client.Disconnect(); . . The method Upload: public void Upload(string filename) { FileInfo fileInfo = new FileInfo(filename); Packet packet = new Packet() { Filename = fileInfo.Name, Content = File.ReadAllBytes(filename) }; byte[] serializedPacket = Tools.Serialize(packet); netStream.Write(serializedPacket, 0, serializedPacket.Length); netStream.Flush(); } netStream (NetworkStream) is opened on Connect method, and closed on Disconnect. Where's the black hole? Can I send multiple objects as I'm trying to do? Thanks for your time.

  • PHP, jQuery and Ajax Object Orientation

    - by pastylegs
    I'm a fairly experienced programmer getting my head around PHP and Ajax for the first time, and I'm having a bit of trouble figuring out how to incorperate object oriented PHP into my ajax webapp. I have an admin page (admin.php) that will load and write information (info.xml) from an XML file depending on the users selection of a form on the admin page. I have decided to use an object (ContentManager.php) to manage the loading and writing of the XML file to disk, i.e : class ContentManager{ var $xml_attribute_1 ... function __construct(){ //load the xml file from disk and save its contents into variables $xml_attribute = simplexml_load_file(/path/to/xml) } function get_xml_contents(){ return xml_attribute; } function write_xml($contents_{ } function print_xml(){ } } I create the ContentManager object in admin.php like so <?php include '../includes/CompetitionManager.php'; $cm = new CompetitionManager() ?> <script> ...all my jquery </script> <html> ... all my form elements </html> So now I want to use AJAX to allow the user to retrieve information from the XML file via the ContentManger app using an interface (ajax_handler.php) like so <?php if(_POST[]=="get_a"){ }else if() } ... ?> I understand how this would work if I wasn't using objects, i.e. the hander php file would do a certain action depending on a variable in the .post request, but with my setup, I can't see how I can get a reference to the ContentManager object I have created in admin.php in the ajax_handler.php file? Maybe my understanding of php object scope is flawed. Anyway, if anyone can make sense of what I'm trying to do, I would appreciate some help!

    Hello, I've been developing an iPhone app for the last few months. Recently I wanted to up performance and cache a few of the images that are used in the UI. The images are downloaded randomly from the web by the user so I can't add specific images to the project. I'm also already using NSUserDefaults to save other info within the app. So now I'm attempting to save a dictionary of UIImages to my NSUserDefaults object and get... -[UIImage encodeWithCoder:]: unrecognized selector sent to instance I then decided to subclass UIImage with a class named UISaveableImage and implement NSCoding. So now I'm at... @implementation UISaveableImage -(void)encodeWithCoder:(NSCoder *)encoder { [encoder encodeObject:super forKey:@"image"]; } -(id)initWithCoder:(NSCoder *)decoder { if (self=[super init]){ super = [decoder decodeObjectForKey:@"image"]; } return self; } @end which isn't any better than where I started. If I was able to convert an UIImage to NSData I would be good, but all I can find are function like UIImagePNGRepresentation which require me to know what type of image this was. Something that UIImage doesn't allow me to do. Thoughts? I feel like I might have wandered down the wrong path...

  • Managing common components with Fossil CVS

    - by Larry Lustig
    I'm a Fossil (and CVS configuration novice) attempting to create and manage a set of distributed Fossil repositories for a Delphi project. I have the following directory tree: Projects Some Project Delphi Components LookupListView Some Client Some Project For Client Some Other Project For Client Source Code Project Resources Project Database I am setting up Fossil version control in order to version and share Projects\Some Client\Some Other Project For Client\Source Code, which contains Delphi 2010 source for a database project. This project makes use of Projects\Delphi Components\LookupListView which is a Delphi component. I need this code to be included in the versioning system for my project. I will, in theory, need to include it in other Fossil repositories in the future, as well. If I create my Fossil repository at the Source Code or Some Other Project For Client level, I cannot add any code above that level to my repository. What is the proper way to deal with this? The two solutions that occur to me are 1) Creating a separate repository for LookupListView and make sure that everyone who uses a repository for a project that references it "knows" that they must also get the current version of this project as well. This seems to defeat the purpose of being able to obtain a complete, current version of the project with a single checkout. The problem is magnified because there are other common component dependencies in this project. 2) Establishing my Fossil repository in the Projects directory, so I can check in files from various subfolders. This seems to me to involve an awful lot of extra path-typing when doing adds, and also to impose my directory structure (Some Client\Some Other Project For Client\Source) on the other users of the repository -- in this case, the actual client. Any suggestions appreciated.

  • python: nonblocking subprocess, check stdout

    - by Will Cavanagh
    Ok so the problem I'm trying to solve is this: I need to run a program with some flags set, check on its progress and report back to a server. So I need my script to avoid blocking while the program executes, but I also need to be able to read the output. Unfortunately, I don't think any of the methods available from Popen will read the output without blocking. I tried the following, which is a bit hack-y (are we allowed to read and write to the same file from two different objects?) import time import subprocess from subprocess import * with open("stdout.txt", "wb") as outf: with open("stderr.txt", "wb") as errf: command = ['Path\\To\\Program.exe', 'para', 'met', 'ers'] p = subprocess.Popen(command, stdout=outf, stderr=errf) isdone = False while not isdone : with open("stdout.txt", "rb") as readoutf: #this feels wrong for line in readoutf: print(line) print("waiting...\\r\\n") if(p.poll() != None) : done = True time.sleep(1) output = p.communicate()[0] print(output) Unfortunately, Popen doesn't seem to write to my file until after the command terminates. Does anyone know of a way to do this? I'm not dedicated to using python, but I do need to send POST requests to a server in the same script, so python seemed like an easier choice than, say, shell scripting. Thanks! Will

  • Changing URI suffix in Joomla when adding child php pages

    - by Sleem
    I have added a new directory in my joomla website: http://sitedomain.tld/xxx/ then I have added index.php in that directory here is the code define( '_JEXEC', 1 ); define('JPATH_BASE', '..' ); define( 'DS', DIRECTORY_SEPARATOR ); require_once ( '../includes/defines.php' ); require_once ( '../includes/framework.php' ); //JDEBUG ? $_PROFILER->mark( 'afterLoad' ) : null; /** * CREATE THE APPLICATION * * NOTE : */ $mainframe =& JFactory::getApplication('site'); $template_name = $mainframe->getTemplate();; $mainframe->initialise(); JPluginHelper::importPlugin('system'); /** * ROUTE THE APPLICATION * * NOTE : */ $mainframe->route(); // authorization $Itemid = JRequest::getInt( 'Itemid'); $mainframe->authorize($Itemid); // trigger the onAfterRoute events //JDEBUG ? $_PROFILER->mark('afterRoute') : null; //$mainframe->triggerEvent('onAfterRoute'); /** * DISPATCH THE APPLICATION * * NOTE : */ $option = JRequest::getCmd('option'); //$mainframe->dispatch($option); // trigger the onAfterDispatch events //JDEBUG ? $_PROFILER->mark('afterDispatch') : null; //$mainframe->triggerEvent('onAfterDispatch'); /** * RENDER THE APPLICATION * * NOTE : */ $mainframe->render(); /** * RETURN THE RESPONSE */ var_dump($document->getHeadData()); echo JResponse::toString($mainframe->getCfg('gzip')); sdwdwd wdwd When I view this page in the browser, all the dynamic links like CSS, JS and images were suffixed by the /xxx/ path which make them broken ! How can I drop this suffix or how do I change this suffix from /xxx to / to it points to the original files location? I have tried setting the JDocument::setBase and also tried to play with the JURI object and changed its _path and _uri without any change Thanks

  • How to configure for multiple gettext domains with babel, pylons, setuptools

    - by ICanHaveSpam
    While trying to internationalize my pylons web and mobile application, 'myapp', Im finding that I would like to keep separate gettext pot files for separate domains. There will be common msgid values for both web and mobile users and there will also be unique msgid values that are only translated for web or mobile users. Im expecting localized msgstrs for mobile users will be different (more terse) than the localized msgstrs for normal web users. The environment is like: the same myapp/controllers will be used for both mobile and web requests. mobile users will have their pages rendered from myapp/templates/mobile normal web users will have their pages rendered from myapp/templates/web What happens by default: I end up with myapp/i18n/myapp.pot and myapp/i18n/*/LC_MESSAGES/myapp.[pm]o files that contain msgid values from controllers and both sets of templates. What Im looking for: to set the gettext domain for the user's session when I decide which templates will render their responses. myapp's msgids from controllers and web template extract into myapp/i18n/web.pot myapp's msgids from controllers and mobile templates extract into myapp/i18n/mobile.pot babel's init_catalog, update_catalog, and compile_catalog runs deal with these separate domains and create separate po and mo localization files. Where Im lost: configuring myapp's setup.cfg and setup.py to deal with separate gettext domains so that I can direct extracted msgid values into a particular pot file based on the path of the python and template files.

  • Netbeans and EOF

    - by sqlnoob
    Hey there, Java, ANTLR and Netbeans newbie here. I have installed a jdk and netbeans. I started a new project on netbeans 6.8 and i have added the antlr-3.2.jar as a library. I also created a lexer and parser class using AntlrWorks. These classes are named ExprParser.java and ExprLexer.java. I copied them into a directory named path-to-netbeans-project/src/parsers. I have a main file: package javaapplication2; import org.antlr.runtime.*; import parsers.*; public class Main { public static void main(String[] args) throws Exception{ ANTLRInputStream input = new ANTLRInputStream(System.in); ExprLexer lexer = new ExprLexer(input); CommonTokenStream tokens = new CommonTokenStream(lexer); ExprParser parser = new ExprParser(tokens); parser.prog(); } } The application builds fine. The book I'm reading says I should run the program and type in some stuff and then press Ctrl+Z (I'm on windows) to send EOF to the console. Problem is that nothing happens when I press Ctrl+z in the netbeans console. When I run from the command line, ctrl+z works fine. This is probably WAY too much information, but I can't figure it out. Sorry. Probably not a good idea to learn 3 new technologies at once.
