• Maven/TestNG reports "Failures: 0" but then "There are test failures.", what's wrong?

  - by JohnS

  I'm using Maven 2.2.1 r801777, Surefire 2.7.1, TestNG 5.14.6, Java 1.6.0_11 on Win XP. I have only one test class with one empty test method and in my pom I have just added TestNG dependency.

• Someone please help google create instuctions that windows users understand. googles "instructions"

  - by nathan

  Below are the only instructions i managed to find from google on how to install the android NDK, it is written as if we all run Linux and presumes we all understand what these obscure tools are. My comments and questions appear in Italics if somone who knows unix and windows would translate for google that would be great! Android NDK Installation Introduction: Please read docs/OVERVIEW.TXT to understand what the Android NDK is and is not. This file gives instructions on how to properly setup your NDK. I. Requirements: The Android NDK currently requires a Linux, OS X or Windows host operating system. Windows users will need to install Cygwin (http://www.cygwin.com) to use it. Note that running the NDK under MSys is not supported. You will need to have the Android SDK and its dependencies installed. The NDK cannot generate final application packages (.apk files), only the shared library files that can go into them. IMPORTANT: The Android NDK can only be used to target system images using the Cupcake (1.5) or later releases of the platform. This is due to subtle toolchain and ABI related changed that make it incompatible with 1.0 and 1.1 system images. The NDK requires GNU Make 3.81 or later being available on your development system. Earlier versions of GNU Make might work but have not been tested. You can check this by running 'make -v' from the command-line. The output should look like: GNU Make 3.81 Copyright (C) 2006 Free Software Foundation, Inc. ... On certain systems, GNU Make might be available through a different command like 'gmake' or 'gnumake'. For these systems, replace 'make' by the appropriate command when invoking the NDK build system as described in the documentation. Great some strange thing called gnu make.. if your not going to tell me what it does maybe you then at least you could give me a URL to it? The NDK also requires a Nawk or GNU Awk executable being available on your development system. Note that the original 'awk' program doesn't implement the 'match' and 'substr' functions used by the NDK build system. Ok another tool, with 1 of 2 possible names, but not the third... and again where should i download this?? On Windows, you will need to install a recent release of Cygwin to use the NDK. See http://www.cygwin.com for instructions. Woohoo a URL! download took about a day because these install instructions do not specify what parts to download. II. Preparing your installation prebuilt cross-toolchain binaries: After installing and unarchiving the NDK, you will need to run the following command from the root folder: build/host-setup.sh hello? windows dont run nothing but .exe .com or .dll, just tell me how you want me to run it.. This will test your setup and make sure the NDK can work properly. Nothing is said about where any of these things need to be installed to (what directory)

• How do I properly add existing source code files to my Xcode project?

  - by BeachRunnerJoe

  I'm new to iPhone development and I'm still getting familiar with the Mac dev environment, including Xcode. I want to add some 3rd party code to my iPhone project, but when I add the "existing files" to my Xcode project, I'm presented with a dialog box that has far too many options that I don't understand and, as such, my project isn't working. When I #import headerfilename.h, I get a build error that reads headerfilename.h: No such file or directory. Can anyone explain to me what all these options mean or give me a link to some documentation that can? I'm having a hard time finding anything in Apple's docs. Which options do I want to choose to add existing source code files to my Xcode project? I should note that the source code files that I'm trying to add are located in my project/Classes/frameworkname/ directory. After they're added, do I need to reference this new code directory in my project settings anywhere (i.e. some kind of header file directory variable)? Thanks so much! Update: I found the following answers/responses on the apple dev forums that were very useful and helped me fix my issue... To make it simple : - if you do not check the copy option, the file stay where it is. - if you check it, it is copied in your project folders In the first case (what it seems you are doing) you need to tell the compiler that the header files are in another directory : - project info - build - search paths - User Header Search Path : add the directory from where you took the header file Hope this will help You have discovered the most confusing dialog box that ever came out of Cupertino. Six years of Xcode, and this thing still is partly a mystery to me. To even get that far, I had to make many test projects to try and reverse-engineer what this thing does. The "Copy" box means that it will copy the files as they are right now, into the project. If this box is not checked, then it just references those files during a build and copies them as they are at THAT time. For source code, you want the Copy box checked. The "relative to" is a total mystery to me and I can't help you with that. I usually leave it however it is already set. Does it mean relative to where they are on disk, or the arrangement in Xcode, or in the bundle? Who knows. The last 2 radio buttons SEEM to mean that it will either re-create the folder structure of the folder you are adding, or just put "fake" folders in Xcode that point to the real folders. This is probably your problem - you are adding source code that is not all at the top level, and when it goes to find it, it does not re-create the hierarchy. Others can supply a better way, hopefully, but what I would do is put all of the source in one folder and add that, using the Copy box. Then in Xcode you can make whatever bogus folders you want and put the source file names in those fake folders.

• Why does jquery leak memory so badly?

  - by Thomas Lane

  This is kind of a follow-up to a question I posted last week: http://stackoverflow.com/questions/2429056/simple-jquery-ajax-call-leaks-memory-in-ie I love the jquery syntax and all of its nice features, but I've been having trouble with a page that automatically updates table cells via ajax calls leaking memory. So I created two simple test pages for experimenting. Both pages do an ajax call every .1 seconds. After each successful ajax call, a counter is incremented and the DOM is updated. The script stops after 1000 cycles. One uses jquery for both the ajax call and to update the DOM. The other uses the Yahoo API for the ajax and does a document.getElementById(...).innerHTML to update the DOM. The jquery version leaks memory badly. Running in drip (on XP Home with IE7), it starts at 9MB and finishes at about 48MB, with memory growing linearly the whole time. If I comment out the line that updates the DOM, it still finishes at 32MB, suggesting that even simple DOM updates leak a significant amount of memory. The non-jquery version starts and finishes at about 9MB, regardless of whether it updates the DOM. Does anyone have a good explanation of what is causing jquery to leak so badly? Am I missing something obvious? Is there a circular reference that I'm not aware of? Or does jquery just have some serious memory issues? Here is the source for the leaky (jquery) version: <html> <head> <script type="text/javascript" src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load('jquery', '1.4.2'); </script> <script type="text/javascript"> var counter = 0; leakTest(); function leakTest() { $.ajax({ url: '/html/delme.x', type: 'GET', success: incrementCounter }); } function incrementCounter(data) { if (counter<1000) { counter++; $('#counter').text(counter); setTimeout(leakTest,100); } else $('#counter').text('finished.'); } </script> </head> <body> <div>Why is memory usage going up?</div> <div id="counter"></div> </body> </html> And here is the non-leaky version: <html> <head> <script type="text/javascript" src="http://yui.yahooapis.com/2.8.0r4/build/yahoo/yahoo-min.js"></script> <script type="text/javascript" src="http://yui.yahooapis.com/2.8.0r4/build/event/event-min.js"></script> <script type="text/javascript" src="http://yui.yahooapis.com/2.8.0r4/build/connection/connection_core-min.js"></script> <script type="text/javascript"> var counter = 0; leakTest(); function leakTest() { YAHOO.util.Connect.asyncRequest('GET', '/html/delme.x', {success:incrementCounter}); } function incrementCounter(o) { if (counter<1000) { counter++; document.getElementById('counter').innerHTML = counter; setTimeout(leakTest,100); } else document.getElementById('counter').innerHTML = 'finished.' } </script> </head> <body> <div>Memory usage is stable, right?</div> <div id="counter"></div> </body> </html>

• I'm looking for an online ASP.NET tutor.

  - by pkiyan

  $15/hr. I know it's not much but... Hi. I'm looking for an ASP.NET tutor. I want to use a remote desktop application so we can see each others screens and use Skype or phone to communicate with. You won't need to come up with any lessons or anything like that. I was thinking we could spend an hour or two each time we logged in to build a decent sized website from scratch. That's basically it. I'm a beginner with about 2 months experience with ASP.NET so we won't have to start from the very beginning, but pretty close. I wanted this site to have a little complexity to it and not just a website for beginners, but something I could study for a while. I'll pay you through PayPal or some other method if you prefer. By the way, it doesn't have to be a website that we work on together. I'll listen to other suggestions too. Maybe we could use an open source site/app to walk-through and study and modify. I've looked at 'My Web Pages Starter Kit 1.30', 'SubText 2.1.2', 'nopCommerce 1.5', and some others. They were all beyond me, and I couldn't make sense of any of the source code. But if you use and are really familiar with an open source app/site that I can download, we could study that. Here are some technical specs about the site I'd like to build/study: ASP.NET 2.0+ (preferably 3.5+, but I don't really care) C# / VB.NET ( don't really care, I suck at both. This is more about ASP.NET and helping me understand the structure of an ASP.NET website and the .NET framework in general. ) SQL Server ( I have SQL Server 2008 express and would someday like to learn how to use this thing. ) JavaScript / AJAX ( at least some use of this ) XML ( basically, I'd like to spend some time in the web.config file, and have some sense of what's going on in there. ) ASP.NET Folders ( I'd like to work with all of the ASP.NET folders if possible: App_Code, App_GlobalResources, etc.. and understand what does/doesn't go in them. Hopefully we can build more than one theme too. ) Assemblies ( how do you create a .dll and use it across different websites? maybe you could suggest a third party .dll that we could use ) Web Service ( I read about this once but didn't really get it ) I can't think of anything else but the above will definitely keep me busy. Hopefully we could make use of a lot of the server controls too (the nav controls gave me a headache when I tried customizing them). Is someone willing to help? I'll pay through PayPal 15 bucks an hour. I live in the Dallas, Texas (US) area so we'd have to synchronize time zones and agree on a day(s)/time of the week. I prefer working at night and on the weekends because I work during the week but whatever your schedule allows too. If you'd like to help me, can you post: years of experience with ASP.NET, your Time zone and time you're available and any ideas you might have about how you'd like to tutor? THANK YOU.

• Error when opening .tar.gz via Shell to install Apache Maven

  - by adamsquared

  Thank you in advance for the help. My Goal: To install apache maven per its websites instructions (http://maven.apache.org/download.html), in order to install the JUNG package according to its install instructions (http://sourceforge.net/apps/trac/jung/wiki/JUNGManual), so I can use the JUNG classes in various Java GUIs. The Problem: I get an error message when I try to extract the apache-maven .gz (install?) file in shell. Background: I'm trying to install the JUNG (http://jung.sourceforge.net/index.html) package to my system's Java, so I can write object-oriented code using various GUIs (Ecliplse, Dr. Java) using the classes in JUNG. I don't understand how the building/installing process works, and how I can get what I build/install to work on various GUIs and the command line. I'm new to shell and the command line, and mostly have experience using a simple IDE (DrJava, Python IDLE, R GUI) to write and compile object-oriented code. Machine: Mac OSX 10.5.8 32-bit. The Instructions: For the maven building Extract the distribution archive, i.e. apache-maven-3.0.4-bin.tar.gz to the directory you wish to install Maven 3.0.4. These instructions assume you chose /usr/local/apache-maven. The subdirectory apache-maven-3.0.4 will be created from the archive. ... for the JUNG installation Appendix: How to Build JUNG This is a brief intro to building JUNG jars with maven2 (the build system that JUNG currently uses). First, ensure that you have a JDK of at least version 1.5: JUNG 2.0+ requires Java 1.5+. Ensure that your JAVA_HOME variable is set to the location of the JDK. On a Windows platform, you may have a separate JRE (Java Runtime Environment) and JDK (Java Development Kit). The JRE has no capability to compile Java source files, so you must have a JDK installed. If your JAVA_HOME variable is set to the location of the JRE, and not the location of the JDK, you will be unable to compile. Get Maven Download and install maven2 from maven.apache.org: http://maven.apache.org/download.html At time of writing (early December 2009), the latest version was maven-2.2.1. Install the downloaded maven2 (there are installation instructions on the Maven website). Follow the installation instructions and confirm a successful installation by typing 'mvn --version' in a command terminal window. Get JUNG ... What I Did: I downloaded the file apache-maven-2.2.1-bin.tar.gz. The JUNG website specified to use apache maven 2. I wanted to stick to the recommended installation instructions, but I couldn't get to /usr on my GUI (i've noticed you click on the MacHD symbol on the desktop its missing several directories/folders that you can see using the shell using the ls command at root directory I couldn't find a way to access the file using my mac GUI. Therefore, I used the shell to navigate to the root directory and then to /usr/local, and used the mkdir command to make the directory apache-maven and entered it. I then moved the file using the mv command. Next I tried extracting the file using tar -zxvf apache-maven-2.2.1-bin.tar.gz. The Error Message: tar: apache-maven-2.2.1/direcoryandfile: Cannot open: No such file or directory ... apache-maven-2.2.1/lib/ext: Cannot mkdir: No such file or directory apache-maven-2.2.1/lib/ext/README.txt tar: apache-maven-2.2.1/lib/ext/README.txt: Cannot open: No such file or directory tar: Error exit delayed from previous errors From what I can tell the archive file is missing some directories or something. I tried deleting the file, redownloading the .tar.gz file from a different mirror and repeating the process. Same result. Thanks again for the help

• How can I tell the size of my app during development?

  - by Newbyman

  My programming decissions are directly related to how much room I have left, or worse perhaps how much I need to shave off in order to get up the 10mb limit. I have read that Apple has quietly increased the 3G & Edge download limit from 10mb up to 20mb in preparation for the iPad in April. Either way, my real question is how can I gauge a rough estimate of how large my app will end while I'm still in the development phase? Is the file size of my development folder roughly 1 to 1 ratio? Is the compressed file size of my development a better approximation? My .xcodeproj file is only a couple hundred kB, but the size of my folder is 11.8 MB. I have a .sqlite database, less than 20 small png images and a Settings.Bundle. The rest are unknown Xcode files related to build, build for iphoneOS, simulator etc.... My source code is rather large with around 1000 lines in most of the major controllers, all in all around 48 .h&.m files. But my classes folder inside my development folder is less than 800kb. Digging around inside my Build file, there is lots of iphone simulator files and debugging files which I don't think will contribute to the final product. The Application file states that it is around 2.3 MB. However, this is such a large difference from the 11.8 MB, I have to wonder if this is just another piece of the equation. I have the app on the my device, I'm in the testing phase. Therefore, I though that I would try to see how large the working version was on the device by checking in iTunes, however my development app is visible on the right-hand the application's iphone screen, but no information about the app most importantly its size. I also checked in Organizer, I used the lower portion of the screen-(Applications), found my application and selected the drop down arrow which gave my "Application Data" and a download arrow button to the right to save a file on my desktop, named with the unique AppleID. Inside the folder it had three folders-(documents, library, tmp) the documents had a copy of my .sqlite database, the library a few more files but not anything obvious or of size, and the tmp was empty. All in all the entire folder was only 164kb-which tells me that this is not the right place to find the size either. I understand that the size is considered to be the size of my binary plus all the additional files and images that I have add. Does anyone have a effective way of guaging how large the binary is or the relating the development folder size to what the final App Store application size will end up. I know that questions have been posted with similar aspects, but I could not find any answered post that really described...what files, or how to determine size specifically. I know that this question looks like a book, but I just wanted to be specific in conveying exactly what I'm looking for and the attempts thus far. *Note all files are unzipped and still in regular working Xcode order of a single app with no brought-in builds or referenced projects. I'm sure that this is straight forward, I just don't know where to look?

• maven test cannot load cross-module resources/properties ?

  - by smallufo

  I have a maven mantained project with some modules . One module contains one XML file and one parsing class. Second module depends on the first module. There is a class that calls the parsing class in the first module , but maven seems cannot test the class in the second module. Maven test reports : java.lang.NullPointerException at java.util.Properties.loadFromXML(Properties.java:851) at foo.firstModule.Parser.<init>(Parser.java:92) at foo.secondModule.Program.<init>(Program.java:84) In "Parser.java" (in the first module) , it uses Properties and InputStream to read/parse an XML file : InputStream xmlStream = getClass().getResourceAsStream("Data.xml"); Properties properties = new Properties(); properties.loadFromXML(xmlStream); The "data.xml" is located in first module's resources/foo/firstModule directory , and it tests OK in the first module. It seems when testing the second module , maven cannot correctly load the Data.xml in the first module . I thought I can solve the problem by using maven-dependency-plugin:unpack to solve it . In the second module's POM file , I add these snippets : <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-dependency-plugin</artifactId> <version>2.1</version> <executions> <execution> <id>data-copying</id> <phase>test-compile</phase> <goals> <goal>unpack</goal> </goals> <configuration> <artifactItems> <artifactItem> <groupId>foo</groupId> <artifactId>firstModule</artifactId> <type>jar</type> <includes>foo/firstModule/Data.xml</includes> <outputDirectory>${project.build.directory}/classes</outputDirectory> </artifactItem> </artifactItems> </configuration> </execution> </executions> </plugin> In this POM file , I try to unpack the first module , and copy the Data.xml to classes/foo/firstModule/ directory , and then run tests. And indeed , it is copied to the right directory , I can find the "Data.xml" file in "target/classes/foo/firstModule" directory. But maven test still complains it cannot read the File (Properties.loadFromXML() throws NPE). I don't know how to solve this problem. I tried other output directory , such as ${project.build.directory}/resources , and ${project.build.directory}/test-classes , but all in vain... Any advices now ? Thanks in advanced. Environments : Maven 2.2.1 , eclipse , m2eclipse

• dynamically include zipfilesets into a WAR

  - by Konstantin

  hi all - a bit of clumsy situation but for the moment we cannot migrate to more straight-forward project layout. We have a project called myServices and it has 2 source folders (yes, I know, but that's the way it is for now) - I'm trying to make build process a bit more flexible so we now have a property called artifact.names that will be parsed by generic build.xml and based on name, it will call either jar or war task, eg. myService-war will create a WAR file with the following zipfilesets included there: myService-war-classes, myService-war-web-inf, myService-war-meta-inf. I want to add a bit more flexibility, and allow having additional zipfilesets, eg. myService-war-etc-1,2 etc - so these will be picked up by the package target automatically. I cannot use "if" inside war target, and also ${ant.refid:myService-war-classes} property is not resolved, so I'm kind of stuck at the moment with my options - how do I dynamically include a zipfileset into a WAR? You can refer to fileset by id, but it MUST be defined then, eg. you can't have it optional on project level. Thank you. Some build.xml snippets: <target name="archive"> <for list="${artifact.names}" param="artifact"> <sequential> <echo>Packaging artifact @{artifact} of project ${project.name}</echo> <property name="display.@{artifact}.packaging" refid="@{artifact}.packaging" /> <echo>${display.@{artifact}.packaging}</echo> <propertyregex property="@{artifact}.archive.type" input="@{artifact}" regexp="([a-zA-Z0-9]*)(\-)([ejw]ar)" select="\3" casesensitive="false"/> <propertyregex property="@{artifact}.base.name" input="@{artifact}" regexp="([a-zA-Z0-9]*)(\-)([ejw]ar)" select="\1" casesensitive="false"/> <echo>${@{artifact}.archive.type}</echo> <if> <then> <war destfile="${jar.dir}/${@{artifact}.base.name}.war" compress="true" needxmlfile="false"> <resources refid="@{artifact}.packaging" /> <zipfileset refid="@{artifact}-classes" erroronmissingdir="false" /> <zipfileset refid="@{artifact}-meta-inf" erroronmissingdir="false" /> <zipfileset refid="@{artifact}-web-inf" erroronmissingdir="false" /> <!-- Additional zipfilesets to package --> <zipfileset refid="@{artifact}-etc-2" erroronmissingdir="false" /> <zipfileset refid="@{artifact}-etc-3" erroronmissingdir="false" /> <zipfileset refid="@{artifact}-etc-4" erroronmissingdir="false" /> <zipfileset refid="@{artifact}-etc-5" erroronmissingdir="false" /> <zipfileset refid="@{artifact}-etc-6" erroronmissingdir="false" /> <zipfileset refid="@{artifact}-etc-7" erroronmissingdir="false" /> <zipfileset refid="@{artifact}-etc-8" erroronmissingdir="false" /> <zipfileset refid="@{artifact}-etc-9" erroronmissingdir="false" /> <zipfileset refid="@{artifact}-etc-10" erroronmissingdir="false" /> </war> </then> <!-- Generic JAR packaging --> <else> <jar destfile="${jar.dir}/@{artifact}.jar" compress="true"> <resources refid="@{artifact}.packaging" /> <zipfileset refid="@{artifact}-meta-inf" erroronmissingdir="false" /> </jar> </else> </if> </sequential> </for> </target>

• AIDL based two way communication

  - by sshasan

  I have two apps between which I want some data exchanged. As they are running in different processes, so, I am using AIDL to communicate between them. Now, everything is happening really great in one direction (say my apps are A and B) i.e. data is being sent from A to B but, now I need to send some data from B to A. I noticed that we need to include the app with the AIDL in the build path of app where the AIDL method will be called. So in my case A includes B in its build path. For B to be able to send something to A, by that logic, B would need A in its build path. This would create a cycle. I am stuck at this point. And I cannot think of a work around this loop. Any help would be greatly appreciated :) . Thanks! ----EDIT---- So, I following the advice mentioned in one of the comments below, I have the following code In the IPCAIDL project the AIDL file resides, its contents are package ipc.android.aidl; interface Iaidl{ boolean pushBoolean(boolean flag); } This project is being used as a library in both the IPCServer and the IPC Client. The IPCServer Project has the service which defines what happens with the AIDL method. The file is booleanService.java package ipc.android.server; import ipc.android.aidl.Iaidl; import android.app.Service; import android.content.Intent; import android.os.IBinder; import android.os.RemoteException; import android.util.Log; public class booleanService extends Service { @Override public IBinder onBind(Intent intent) { return new Iaidl.Stub() { @Override public boolean pushBoolean(boolean arg0) throws RemoteException { Log.i("SERVER(IPC AIDL)", "Truth Value:"+arg0); return arg0; } }; } } The IPCClient file which calls this method is package ipc.android.client2; import ipc.android.aidl.Iaidl; import android.app.Activity; import android.content.ComponentName; import android.content.Context; import android.content.Intent; import android.content.ServiceConnection; import android.os.Bundle; import android.os.IBinder; import android.os.RemoteException; import android.view.View; import android.widget.Button; public class IPCClient2Activity extends Activity { Button b1; Iaidl iAIDL; boolean k = false; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); bindService(new Intent("ipc.android.server.booleanService"), conn, Context.BIND_AUTO_CREATE); startService(new Intent("ipc.android.server.booleanService")); b1 = (Button) findViewById(R.id.button1); b1.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if(k){ k = false; } else{ k = true; } try { iAIDL.pushBoolean(k); } catch (RemoteException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }); } private ServiceConnection conn = new ServiceConnection() { @Override public void onServiceDisconnected(ComponentName name) { // TODO Auto-generated method stub } @Override public void onServiceConnected(ComponentName name, IBinder service) { iAIDL = Iaidl.Stub.asInterface(service); } }; } The manifest file for IPCServer includes the declaration of the service.

• Faulty to use memcache together with a php web-browser-game in this way?

  - by Crowye

  Background We are currently working on a strategy web-browser game based on php, html and javascript. The plan is to have 10,000+ users playing within the same world. Currently we are using memcached to: store json static data, language files store changeable serialized php class objects (such as armies, inventorys, unit-containers, buildings, etc) In the back we have a mysql server running and holding all the game data aswell. When a object is loaded through our ObjectLoader it loads in this order: checks a static hashmap in the script for the object checks memcache if it has already been loaded into it otherwise loads from database, and saves it into memcache and the static temp hashmap We have built the whole game using a class-object-oriented approach where functionality is always made between objects. Beause of this we think we have managed to get a nice structure, and with the help of memcached we have received good request times from client-server when interacting with the game. I'm aware that memcache is not synchronized, and also is not commonly used for holding a full game in memory. In the beginning after a server's startup the load times when loading objects into memcache for the first time will be high, but after the server's been online for a while and most loads are from memcache, the loads will be well reduced. Currently we are saving changed objects into memcache and database at the same time. Earlier we had an idea to save objects into db only after a certain time or at intervals, but due to risk inconsistency if the memcache/server went down, we skipped it for now. Client requests to server often return object's status simple json-format without changing the object, which in turn is represented in the browser visually with images and javascript. But from time to time depending on when an object was last updated, it updates them with new information (e.g. a build-queue holding planned buildings time-progress is increased, and/or planned-queue-items-array has changed). Questions: Do you see how this could work or are we walking in blindness here? Do you expect us to have a lot of inconsistency issues if someone loads and updates the a memcache objects while someone else does the same? Is it even doable to do it in the way he have done it? Seems to be working fine atm, but so far we have only been 4 people online at the same time.. Is some other cache program more fit for this class-object approach than memcached? Is there any other tips you have for this situation? UPDATE Since it is simply a "normal webpage" (no applet, flash, etc), we are implementing the game so that the server is the only one holding a "real game-state".. the state of the different javascript-objects on the client is more like a approximative version of the server's game state. From time to time and before you do certain things important things, the client's visual state is updated to the server's state (e.g. the client things he can afford a barracks, asks the server to build a barracks, server updates current resources according to income-data on server and then tries to build a barracks or casts an error-message, and then sends the current server-state on resources, buildings back to the client).. It is not a fast-paced game lika real strategy game. More like a quite slow 3-4 months playtime game, where buildings can take +1 minute up to several days to complete.

• Trying to create an image list based on what is defined as the order, and loosing

  - by user1691463

  I have a custom created module for Joomla 2.5 and within the params of the module, and have a loop that is not outputting as expected. I have the following parameters (fields) int he module: Order Thumb image Image Title Full-size image Now there are 10 sets of these group of 4 params. What I am trying to do is loop through each of the object sets, 10 of them, and on each iteration, build an HTML image list structure. The if statement is building the HTML structure for the sets that have an order value that is greater than 0, and the else is creating the html for those sets that do not have a value greater that 0. The goal is to create two variables and then concatenate the the strings together; the leading set are the sets that have an order defined. This is not happening and every thrid loop seems like it is missing. Here is the order as it is set in the 10 sets Set 1 = 0 Set 2 = 4 Set 3 = 1 Set 4 = 0 Set 5 = 5 Set 6 = 0 Set 7 = 0 Set 8 = 6 Set 9 = 3 Set 10 = 9 However, the outcomes is: 9 5 1 4 6 7 10 Instead of the expected: 3 9 2 5 8 1 (below here are those sets that were not greater than 0 in order of appearance) 4 6 7 whats wrong here that I can not see <?php for ($i = 1; $i <= 10; $i++) { $order = $params->get('order'.$i);#get order for main loop of 10 $active = ""; if ($order > 0) {#Check if greater than 0 for ($n = 1; $n <= 10; $n++) {#loop through all order fields looking and build html lowest to highest; $ordercheck =$params->get('order'.$n); if ($ordercheck == $i) { $img = $params->get('image'.$n); $fimage = $params->get('image'.$n.'fullimage'); $title = $params->get('image'.$n.'alttext'); $active = ""; $active = $active . '<li>'; $active = $active . '<a href="'.$fimage.'" rel="prettyPhoto[gallery1]" title="'.$title.'">'; $active = $active . '<img src="'.$img.'" alt="'.$title.'" />'; $active = $active . '</a>'; $active = $active . '</li>'; $leading = $leading . $active; } } } else { #if the itteration $order was not greater than 0, build in order of accourance $img = $params->get('image'.$i); $fimage = $params->get('image'.$i.'fullimage'); $title = $params->get('image'.$i.'alttext'); $active = $active .

• Templated function with two type parameters fails compile when used with an error-checking macro

  - by SirPentor

  Because someone in our group hates exceptions (let's not discuss that here), we tend to use error-checking macros in our C++ projects. I have encountered an odd compilation failure when using a templated function with two type parameters. There are a few errors (below), but I think the root cause is a warning: warning C4002: too many actual parameters for macro 'BOOL_CHECK_BOOL_RETURN' Probably best explained in code: #include "stdafx.h" template<class A, class B> bool DoubleTemplated(B & value) { return true; } template<class A> bool SingleTemplated(A & value) { return true; } bool NotTemplated(bool & value) { return true; } #define BOOL_CHECK_BOOL_RETURN(expr) \ do \ { \ bool __b = (expr); \ if (!__b) \ { \ return false; \ } \ } while (false) \ bool call() { bool thing = true; // BOOL_CHECK_BOOL_RETURN(DoubleTemplated<int, bool>(thing)); // Above line doesn't compile. BOOL_CHECK_BOOL_RETURN((DoubleTemplated<int, bool>(thing))); // Above line compiles just fine. bool temp = DoubleTemplated<int, bool>(thing); // Above line compiles just fine. BOOL_CHECK_BOOL_RETURN(SingleTemplated<bool>(thing)); BOOL_CHECK_BOOL_RETURN(NotTemplated(thing)); return true; } int _tmain(int argc, _TCHAR* argv[]) { call(); return 0; } Here are the errors, when the offending line is not commented out: 1>------ Build started: Project: test, Configuration: Debug Win32 ------ 1>Compiling... 1>test.cpp 1>c:\junk\temp\test\test\test.cpp(38) : warning C4002: too many actual parameters for macro 'BOOL_CHECK_BOOL_RETURN' 1>c:\junk\temp\test\test\test.cpp(38) : error C2143: syntax error : missing ',' before ')' 1>c:\junk\temp\test\test\test.cpp(38) : error C2143: syntax error : missing ';' before '{' 1>c:\junk\temp\test\test\test.cpp(41) : error C2143: syntax error : missing ';' before '{' 1>c:\junk\temp\test\test\test.cpp(48) : error C2143: syntax error : missing ';' before '{' 1>c:\junk\temp\test\test\test.cpp(49) : error C2143: syntax error : missing ';' before '{' 1>c:\junk\temp\test\test\test.cpp(52) : error C2143: syntax error : missing ';' before '}' 1>c:\junk\temp\test\test\test.cpp(54) : error C2065: 'argv' : undeclared identifier 1>c:\junk\temp\test\test\test.cpp(54) : error C2059: syntax error : ']' 1>c:\junk\temp\test\test\test.cpp(55) : error C2143: syntax error : missing ';' before '{' 1>c:\junk\temp\test\test\test.cpp(58) : error C2143: syntax error : missing ';' before '}' 1>c:\junk\temp\test\test\test.cpp(60) : error C2143: syntax error : missing ';' before '}' 1>c:\junk\temp\test\test\test.cpp(60) : fatal error C1004: unexpected end-of-file found 1>Build log was saved at "file://c:\junk\temp\test\test\Debug\BuildLog.htm" 1>test - 12 error(s), 1 warning(s) ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ========== Any ideas?

I mean... it splits whole words into parts (on special chars) where it shouldn't! so my guess is I should use multibyte functions instead of regular preg_replace... I tried to replace preg_replace with mb_ereg_replace but it is not working as it should... at least not for 2 and 3 words phrases any ideas?

• Troubleshoot Perl module installation on Mac OS X

  - by Daniel Standage

  I'm trying to install the Perl module Set::IntervalTree on Mac OS X. I recently installed it today on an Ubuntu box with no problem. I simply started cpan, entered install Set:IntervalTree, and it all worked out. However, the installation failed on Mac OS X--it spits out a huge list of compiler errors (below).

• Kendo UI Combo Box Reset Value

  - by ciantrius

  I'm using the Kendo UI ComboBoxes in cascade mode to build up a filter that I wish to apply. How do I clear/reset the value of a Kendo UI ComboBox? I've tried: $("#comboBox").data("kendoComboBox").val(''); $("#comboBox").data("kendoComboBox").select(''); $("#comboBox").data("kendoComboBox").select(null); all to no avail. The project is an MVC4 app using the Razor engine and the code is basically the same as the Kendo UI example.

• Autofac Unit Testing using RegisterControllers()

  - by Kane

  I am having problems using Autofac 2.1.13 and writing my unit tests for my ASP.NET MV2 application. I can't seem to resolve controllers when using the RegisterControllers method. I have tried using the Resolve<() and ControllerBuilder.Current.GetControllerFactory().CreateController() methods but to no avail. I am sure that I've missed something simple here so can anyone assist? This was my first attempt at resolving the HomeController - but does not work. ContainerBuilder builder = new ContainerBuilder(); builder.RegisterControllers(typeof(HomeController).Assembly); IContainer container = builder.Build(); // Throws a Throws a A first chance exception of type 'Autofac.Core.Registration.ComponentNotRegisteredException' occurred in Autofac.dll var homeController = container.Resolve<HomeController>(); Similarly this does not work either. ContainerBuilder builder = new ContainerBuilder(); builder.RegisterControllers(typeof(HomeController).Assembly); IContainer container = builder.Build(); var containerProvider = new ContainerProvider(container); ControllerBuilder.Current.SetControllerFactory(new AutofacControllerFactory(containerProvider)); var request = new Mock<HttpRequestBase>(MockBehavior.Loose); request.Setup(r => r.Path).Returns("Path"); var httpContext = new Mock<HttpContextBase>(MockBehavior.Loose); httpContext.SetupGet(c => c.Request).Returns(request.Object); ControllerBuilder.Current.GetControllerFactory().CreateController(new RequestContext(httpContext.Object, new RouteData()), "home"); Any assistance would be greatly appreciated. I should note if I register my controllers without using the RegisterControllers() method my unit tests work. My question would seem to be limited to specifically using the RegisterControllers() method.

• How to use QSerialDevice in Qt?

  - by Tobias

  Hello, I am trying to use QSerialDevice in Qt to get a connection to my serial port. I also tried QextSerialPort before (which works on Windows Vista but unfortunately not on Windows XP ..) but I need an API which supports XP, Vista and Win7... I build the library and configured it this way: CONFIG += dll CONFIG += debug I did use the current version from SVN (0.2.0 - 2010-04-05) and the 0.2.0 zip package. After building the library I did copy it to my Qt Libdir (C:\Qt\2009.05\qt\lib) and also to C:\Windows\system32. Now I try to link against the lib in my project file: LIBS += -lqserialdevice I import the needed header (abstractserial.h) and use my own AbstractSerial like this: // Initialize this->serialPort->setDeviceName("COM1"); if (!this->serialPort->open(QIODevice::ReadWrite | QIODevice::Unbuffered)) qWarning() << "Error" << this->serialPort->errorString(); // Configure SerialPort this->serialPort->setBaudRate(AbstractSerial::BaudRate4800); this->serialPort->setDataBits(AbstractSerial::DataBits8); this->serialPort->setFlowControl(AbstractSerial::FlowControlOff); this->serialPort->setParity(AbstractSerial::ParityNone); this->serialPort->setStopBits(AbstractSerial::StopBits1); The problem is, that if I run my application, it crashes immediately with exit code -1073741515 (application failed to initialize properly). This is the same error I got using QextSerialPort under Windows XP (it worked with Windows Vista). If I build the QSerialDevice lib with release config and also my program, it crashes immediately but with exit code -1073741819 Can someone help me with this program or with another solution of getting a serial port to work with Qt (maybe another API or something?) Otherwise I have to use Windows API functions which would mean that my program won't work with UNIX systems.. If you have a solution for the problem with QextSerialPort under WinXP SP3, they are also welcome ;) Best Regards, Tobias

• SharePoint 2010: CheckSuspiciousPhysicalPath exception

  - by Tommy Jakobsen

  I just installed SharePoint 2010 on my Windows Server 2008 R2 x64 server with SQL Server 2008. Everything is installed on this single server, and I configured SharePoint 2010 as described here: http://sharepoint.microsoft.com/blogs/fromthefield/Lists/Posts/Post.aspx?ID=112 Everything installed correct, and the SQL databases were created. But when I try to access the administration site through http://server:47632/_admin/adminconfigintro.aspx, I get the following exception: [HttpException] at System.Web.Util.FileUtil.CheckSuspiciousPhysicalPath(String physicalPath) at System.Web.CachedPathData.GetConfigPathData(String configPath) at System.Web.CachedPathData.GetConfigPathData(String configPath) at System.Web.CachedPathData.GetConfigPathData(String configPath) at System.Web.HttpContext.GetFilePathData() at System.Web.Configuration.CustomErrorsSection.GetSettings(HttpContext context, Boolean canThrow) at System.Web.HttpResponse.ReportRuntimeError(Exception e, Boolean canThrow, Boolean localExecute) at System.Web.HttpRuntime.FinishRequest(HttpWorkerRequest wr, HttpContext context, Exception e) The same error occurs when accessing http://server:47632/. Do you have any ideas whats causing this? I haven't been able to find anything about this issue. Edit 1: I just tried reinstalling SharePoint 2010 while monitoring the error log. When I run the configuration wizard, the following errors show up in the event log: The site /sites/Help could not be created.

• WCF set bindings on service at runtime

  - by Dave

  My app has to be installed on my client's webservers. Some clients want to use SSL and some do not. My app has a WCF service and I currently have to go into the web.config for each install and switch the security mode from to depending on the client's SSL situation. I am able to set the client bindings at runtime. However, I would like to know if there is a way to set the service bindings at runtime(on the server side).

• Calling a specific contact endpoint with Lync

  - by user1426477

  I'm trying to develop a Lync application that allows a user to select which of a contact's endpoints they would like to call. For instance, if User A has two phones listed, then User B can choose between those two options and call whichever he likes to try and get in contact with them. I know with the regular Lync Client(not suppressed) this appears to be possible, but Im not sure how to accomplish it programatically in UISuppression mode. Any ideas?

• ASP.NET 3.5 GridView - row editing - dynamic binding to a DropDownList

  - by marc_s

  This is driving me crazy :-) I'm trying to get a ASP.NET 3.5 GridView to show a selected value as string when being displayed, and to show a DropDownList to allow me to pick a value from a given list of options when being edited. Seems simple enough? My gridview looks like this (simplified): <asp:GridView ID="grvSecondaryLocations" runat="server" DataKeyNames="ID" OnInit="grvSecondaryLocations_Init" OnRowCommand="grvSecondaryLocations_RowCommand" OnRowCancelingEdit="grvSecondaryLocations_RowCancelingEdit" OnRowDeleting="grvSecondaryLocations_RowDeleting" OnRowEditing="grvSecondaryLocations_RowEditing" OnRowUpdating="grvSecondaryLocations_RowUpdating" > <Columns> <asp:TemplateField> <ItemTemplate> <asp:Label ID="lblPbxTypeCaption" runat="server" Text='<%# Eval("PBXTypeCaptionValue") %>' /> </ItemTemplate> <EditItemTemplate> <asp:DropDownList ID="ddlPBXTypeNS" runat="server" Width="200px" DataTextField="CaptionValue" DataValueField="OID" /> </EditItemTemplate> </asp:TemplateField> </asp:GridView> The grid gets displayed OK when not in editing mode - the selected PBX type shows its value in the asp:Label control. No surprise there. I load the list of values for the DropDownList into a local member called _pbxTypes in the OnLoad event of the form. I verified this - it works, the values are there. Now my challenge is: when the grid goes into editing mode for a particular row, I need to bind the list of PBX's stored in _pbxTypes. Simple enough, I thought - just grab the drop down list object in the RowEditing event and attach the list: protected void grvSecondaryLocations_RowEditing(object sender, GridViewEditEventArgs e) { grvSecondaryLocations.EditIndex = e.NewEditIndex; GridViewRow editingRow = grvSecondaryLocations.Rows[e.NewEditIndex]; DropDownList ddlPbx = (editingRow.FindControl("ddlPBXTypeNS") as DropDownList); if (ddlPbx != null) { ddlPbx.DataSource = _pbxTypes; ddlPbx.DataBind(); } .... (more stuff) } Trouble is - I never get anything back from the FindControl call - seems like the ddlPBXTypeNS doesn't exist (or can't be found). What am I missing?? Must be something really stupid.... but so far, all my Googling, reading up on GridView controls, and asking buddies hasn't helped. Who can spot the missing link? ;-) Marc
