  • Having the output of a Console App in Visual Studio instead of the Console

    - by devoured elysium
    When doing "Console" apps in Java with Eclipse, I see the output being put in a text box on the IDE itself, instead of having a Console popping up like in Visual Studio. This comes in handy, as even after the program has exited, I can still make good use of the text that was written in it, as it doesn't get erased until I run it again. Is it possible to achieve anything like that with Visual Studio? I know that instead of doing System.Console.WriteLine(str); I can do System.Diagnostics.Debug.WriteLine(str); but it is not quite the same thing, as you get a lot of "junk" in the Output window, as all the loaded symbols and such. Even better, is it possible to have everything done in the IDE itself, when you run your app, instead of having the Console running? Thanks

  • Please explain some of Paul Graham's points on LISP

    - by kunjaan
    I need some help understanding some of the points from Paul Graham's article http://www.paulgraham.com/diff.html A new concept of variables. In Lisp, all variables are effectively pointers. Values are what have types, not variables, and assigning or binding variables means copying pointers, not what they point to. A symbol type. Symbols differ from strings in that you can test equality by comparing a pointer. A notation for code using trees of symbols. The whole language always available. There is no real distinction between read-time, compile-time, and runtime. You can compile or run code while reading, read or run code while compiling, and read or compile code at runtime. What do these points mean How are they different in languages like C or Java? Do any other languages other than LISP family languages have any of these constructs now?

  • String length difference between ruby 1.8 and 1.9

    - by Raghu
    I have a website thats running on ruby 1.8.7 . I have a validation on an incoming post that checks to make sure that we allow upto max of 12000 characters. The spaces are counted as characters and tab and carriage returns are stripped off before the post is subjected to the validation. Here is the post that is subjected to validation http://pastie.org/5047582 In ruby 1.9 the string length shows up as 11909 which is correct. But when I check the length on ruby 1.8.7 is turns out to be 12044. I used codepad.org to run this ruby code which gives me http://codepad.org/OxgSuKGZ ( which outputs the length as 12044 which is wrong) but when i run this same code in the console at codeacademy.org the string length is 11909. Can anybody explain me why this is happening ??? Thanks

  • Firebird query is crashing with org.firebirdsql.jdbc.FBSQLException: GDS Exception. 335544364. reque

    - by user321395
    I am using JdbcTemplate.queryForInt to insert a Row into the DB, and then get the ID back. The Query is "INSERT INTO metadocs(NAME) values (?) RETURNING METADOCID". If I run the statement in Flamerobin, it works fine. However, if I run it from Java, I get the following error: org.springframework.jdbc.UncategorizedSQLException: PreparedStatementCallback; uncategorized SQLException for SQL [INSERT INTO metadocs(NAME) values (?)

  • NoSQL vs Ehcache caching advise for speeding up read only mysql Database

    - by paddydub
    I'm building a Route Planner Webapp using Spring/Hibernate/Tomcat and a mysql database, I have a database containing read only data, such as Bus Stop Coordinates, Bus times which is never updated. I'm trying to make the app run faster, each time the application is run it will preform approx 1000 reads to the database to calculate a route. I have setup a Ehcache which greatly improves the read from database times. I'm now setting terracotta + Ehcache distributed caching to share the cache with multiple Tomcat JVMs. This seems a bit complicated. I've tried memcached but it was not performing as fast as ehcache. I'm wondering if a MongoDb or Redis would be better suited. I have no experience with nosql but I would appreciate if anyone has any ideas. What i need is quick access to the read only database.

  • PHP SimpleXML recursive function to list children and attibutes

    - by Phill Pafford
    I need some help on the SimpleXML calls for a recursive function that lists the elements name and attributes. Making a XML config file system but each script will have it's own config file as well as a new naming convention. So what I need is an easy way to map out all the elements that have attributes, so like in example 1 I need a simple way to call all the processes but I don't know how to do this without hard coding the elements name is the function call. Is there a way to recursively call a function to match a child element name? I did see the xpath functionality but I don't see how to use this for attributes. Any ideas? Also does the XML in the examples look correct? can I structure my XML like this? Example 1: <application> <processes> <process id="123" name="run batch A" /> <process id="122" name="run batch B" /> <process id="129" name="run batch C" /> </processes> <connections> <databases> <database usr="test" pss="test" hst="test" dbn="test" /> </databases> <shells> <ssh usr="test" pss="test" hst="test-2" /> <ssh usr="test" pss="test" hst="test-1" /> </shells> </connections> </application> Example 2: <config> <queues> <queue id="1" name="test" /> <queue id="2" name="production" /> <queue id="3" name="error" /> </queues> </config> Pseudo code: // Would return matching process id getProcess($process_id) { return the process attributes as array that are in the XML } // Would return matching DBN (database name) getDatabase($database_name) { return the database attributes as array that are in the XML } // Would return matching SSH Host getSSHHost($ssh_host) { return the ssh attributes as array that are in the XML } // Would return matching SSH User getSSHUser($ssh_user) { return the ssh attributes as array that are in the XML } // Would return matching Queue getQueue($queue_id) { return the queue attributes as array that are in the XML } EDIT: Can I pass two parms? on the first method you have suggested @Gordon public function findProcessById($id, $name) { $attr = false; $el = $this->xml->xpath("//process[@id='$id']"); // How do I also filter by the name? if($el && count($el) === 1) { $attr = (array) $el[0]->attributes(); $attr = $attr['@attributes']; } return $attr; }

  • Silverlight 4 application failing to build in Blend 4 Beta..

    - by loyalpenguin
    Hi, I'm creating a simple silverlight application using Silverlight 4 and Expression Blend 4 Beta, but when I run the Application I get the following Error: C:\Users\WebDevelop1\Documents\Expression\Blend 4 Beta\Projects\SilverlightApplication1\SilverlightApplication1.sln.metaproj : error MSB4126: The specified solution configuration "Debug|HPD" is invalid. Please specify a valid solution configuration using the Configuration and Platform properties (e.g. MSBuild.exe Solution.sln /p:Configuration=Debug /p:Platform="Any CPU") or leave those properties blank to use the default solution configuration. Done building project "SilverlightApplication1.sln" -- FAILED. Build failed. I'm relatively new to silverlight and not really sure where to start. This has happened with every project I have created in Blend, but when I run it in VS2010 it runs perfect. Is this a known issue with the Beta release or am I possibly missing something? Thanks in advance.

  • psexec failing with return code 122 when used from Windows service

    - by Jeremy McGee
    I've written a WCF service as a wrapper around a C# utility we've written that uses the SysInternals psexec utility to run jobs on a remote system. psexec is invoked from C# with command-line parameters that specify the domain, user and password to use. All works fine when I invoke the C# utility from PowerShell locally. However, when I run the utility from the WCF service we see a return code of 122, which corresponds to (?) "The data area passed to a system call is too small". psexec is running against Windows Server 2008. The credentials I'm passing are local administrator, in the same domain as the machine that hosts the service wrapping the utility.

  • Privilege Elevation only when and if required.

    - by Cameron Peters
    My application only very occasionally requires privilege elevation... I need to reference some 3rd party COM components that only work correctly when run as administrator. I would like my application to request privilege elevation only when it needs it... Generally, I don't want my application to run as administrator unless I need to use the 3rd party COM components. I see that CoCreateAsAdmin could potentially solve the problem, but the component author doesn't set up the required registry entries, and I'm not sure how to use CoCreateAsAdmin in C# and in conjuction with Runtime-Callable-Wrapper that is created by tlbimp. Another solution would be to spawn another process, but I have no experience with this yet... I don't want to create a completely separate application... I would be happy to create an assembly that runs in a separated elevated process if someone can show me how to make it work. Thanks...

  • CC.NET Dashboard Error: Could not load type 'System.Security.Authentication.ExtendedProtection.Chann

    - by Leslie
    Late last week I upgraded CC.NET locally and on the build server. The build server is still fine, but locally I am now getting the following error: Exception Details: Exortech.NetReflector.NetReflectorTypeLoadException: Unable to load types from assembly System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089: Failed to load 1 of the 3612 types defined in the assembly.

I'm afraid this started after a batch of Windows updates this morning. I had another two updates that won't run, 979909 and 982168 (I had an update that wouldn't run last month). Anyone else having any issues? Thanks!

  • WiX - create a bootstrap that passes arguments to the msi

    - by Dror Helper
    I need to create a bootstrap for my WiX project I've tried using setupbld.exe but it will only allow me to create an executable that will show my UI or one that will behave as a silent installer but not both. I need to be able to run the resulting executable with argument that will tell it wether or not to show the UI during installation. I've found this post by John Robbins that explains how to re-build the setup.exe stub used in the creation of the bootstrap but I was hoping there is a simpler way to do what I need. Does anyone know of a way to create a bootstrap that I use to run either as a simple (with UI) install or as a silent install.

  • UITableView backgroundColor always gray on iPad

    - by rjobidon
    Hi, When I set the backgroundColor for my UITableView it works fine on iPhone (device and simulator) but NOT on the iPad simulator. Instead I get a light gray background for any color I set including groupTableViewBackgroundColor. Steps to reproduce: Create a new navigation-based project. Open RootViewController.xib and set the table view style to "Grouped". Add this responder to the RootViewController:- (void)viewDidLoad { [super viewDidLoad]; self.view.backgroundColor = [UIColor blackColor]; } Select Simulator SDK 3.2, build and run. You will get a black background (device and simulator). Select your target in the project tree. Click on Project : Upgrade Current Target for iPad. Build and run. You will get a light gray background. Revert the table view style to Plain and you will get a black background. Thanks for your help!

  • Async friendly DispatcherTimer wrapper/subclass

    - by Simon_Weaver
    I have a DispatcherTimer running in my code that fire every 30 seconds to update system status from the server. The timer fires in the client even if I'm debugging my server code so if I've been debugging for 5 minutes I may end up with a dozen timeouts in the client. Finally decided I needed to fix this so looking to make a more async / await friendly DispatcherTimer. Code running in DispatcherTimer must be configurable whether it is reentrant or not (i.e. if the task is already running it should not try to run it again) Should be task based (whether or not this requires I actually expose Task at the root is a gray area) Should be able to run async code and await on tasks to complete Whether it wraps or extends DispatcherTimer probably doesn't really matter but wrapping it may be slightly less ambiguous if you don't know how to use it Possibly expose bindable properties for IsRunning for UI

  • Jmesa table page navigation

    - by Sara
    I am new to Jmesa and am trying to use it on my jsp page. I use exactly same JSP and controller code as the example on http://code.google.com/p/jmesa/wiki/JSPTagExample . The table shows up and looks fine. The problem is non of the buttons on the toolbar are working. E.g. page navigation arrows, etc. What might be wrong with my code( As I said it is exactly same as the example). Should I add extra code for page navigation? Thanks, Sara. Update: I found out what the problem is, after I enter toolbar buttons it routes to "localhost:8080/portal/projectTag.run?maxRows=4&projectTag_tr_=true&projectTag_p_=1&projectTag_mr_=4" "Instead of "localhost:8080/portal/page/projects/projectTag.run?maxRows=4&projectTag_tr_=true&projectTag_p_=1&projectTag_mr_=4" So it doesn't include the "/page/projects" in the url. How can I add that?

  • ASP.NET MVC & Silverlight development - on Ubuntu

    - by queen3
    I recently moved my working environment from Windows 7 to Ubuntu, and enjoy this every minute of my working day. My work is currently to develop ASP.NET MVC and Silverlight applications. Thus, important Windows stuff is being still run in VirtualBox (such as IIS, MSSQL, Silverlight 3, and legacy COM stuff). For now, I use Visual Studio under VirtualBox as editor/IDE/debugger. But since I prefer Ubuntu fonts and UI much more I'd like to move at least editor (and better IDE) to native Ubuntu. Things I have already done: I store project files in my home folder and run Visual Studio from \vboxsvr share. With few tricks for ASP.NET it works. I use svn on Ubuntu. I test my ASP.NET MVC site using FireFox/FireBug on Ubuntu. What I need on Ubuntu: SQL client to manage MSSQL. I mostly need querying, but I would miss SQL intellisense support. I enjoy command-line svn a lot, but there're times when it's not enough (e.g. view files / check diffs / selectively commit at the sames time) so I wonder if there're any addons - I don't mean replacement for svn, just addons for rare cases like above. I wonder if there're editors that can provide some C# intellisense. Yes I know about MonoDevelop, but will it provide intellisense without compiling (since I'm going to compile remotely in Win box)? And pretty big topic, what's the best way (editor/IDE) to do "folder-based" development? What I mean: The project is /trunk. Everything is there. I don't want to manually add files to project or like that. The project is the folder and files down there. Main task is to edit files of course. I need a quick way to open / search for files in the project. Like in Resharper, I can click Ctrl-Shift-T (IIRC) and just type file name, a list of matching files in the project folder and below is shown. For example, gedit has file tree browser, but I can't quickly type XYZ to find all XYZ files there; moreover it doesn't automatically switch focus to/from editor; so it's more mouse-oriented; I need 100% keyboard way. I need syntax highlighting for C#/HTML/JS. Most importantly, I need HTML tags autocompletion. I can live without it, but I'll be sorry. I need to run compilation remotely (via ssh I think, invoking NAnt script which does MSBuild) and grab results such as errors and warnings, and I'd prefer to quickly go to error line/file. In short, I need to edit/search/open/svn/compile/run files in some folder. Looks like a case for command-line, but imaging I'm in /trunk and want to open file.cs inside /trunk/foo/bar/boo/far, I wouldn't want to type all this path even with bash autocompletion help. I'd prefer to enter :open file.cs, and maybe then select from list of file.cs and file1.cs. Well, maybe I'll add more soon. Actually, I don't have exact requirements; for example, I don't even know if I need to ask for IDE or editor; or should it have svn support integrated or I need to use it from console; do people work with files from console (search/commit/delete/etc) and open editor from there, or they work from editor/IDE and manage files (search/commit/delete) from there? What's better? I have a feeling that vim might have everything I need. I'd like to confirm that, before I spend a lot of time learning it. No I don't want Emacs. Any other IDE? I like Eclipse, but is it good for such stuff? And after all, do you feel like it's a good way to go? I enjoy Ubuntu, enjoy learning new stuff, and Ubuntu + Windows in VirtualBox actually runs faster than Windows7 on my mahcine, but maybe I need to keep development (editor/files management/etc) in Windows/VirtualBox only, leaving other stuff for Ubuntu?

  • Build failing - VS2010 solution on TFS2008

    - by Nick
    I have migrated a VS2008 ASP.NET MVC solution to VS2010/MVC2/.NET 4.0 The solution builds locally and all unit tests pass. Our TFS server is still TFS2008 and I am having problems getting the CI build to pass. The projects all build successfully, the unit tests all run and pass but the Running Tests item fails.

  • Android daemon process

    - by J Andy
    Is it possible (without violating any licenses) to write a native C/C++ application on top of the Android OS and make it run as a daemon process? There are already several daemon process' running which one can see with the 'ps' command, the legal part concerns me the most. And also the lack of documentation on how to exactly do this. For the writing part, I guess one could use basic Linux programming concepts, since Android supports at least to some level the standard Posix API. To make it run as the phone boots, some modifications is of course required in init as well. I have no plans to have this app in the Android Market, so installing it manually to the phone is not a problem. As long as it does not require re-compiling the whole OS or kernel. I really appreciate all info on this topic, since there's isn't much available. Thanks.

  • c# Network Programming - HTTPWebRequest Scraping

    - by masterguru
    Hi, I am building a web scraping application. It should scrape a complex web site with concurrent HttpWebRequests from a single host to a single target web server. The application should run on Windows server 2008. One single HttpWebRequest for data could take from 1 minute to 4 minutes to complete (because of long running db operations) I should have at least 100 parallel requests to the target web server, but i have noticed that when i use more then 2-3 long-running requests i have big performance issues (request timeouts/hanging). How many concurrent requests can i have in this scenario from a single host to a single target web server? can i use Thread Pools in the application to run parallel HttpWebRequests to the server? will i have any issues with the default outbound HTTP connection/requests limits? what about Request timeouts when i reach outbound connection limits? what would be the best setup for my scenario? Any help would be appreciated. Thanks

  • tomcat JAXB 1 and 2 linkageerror

    - by Alex
    Hi there, I'm running a tomcat 6, spring, apache cxf webservice, know it is a must to add one third party library to my webapp to fulfill an order. I have jaxb-impl-2.1.12.jar for apache cxf in WEB-INF/lib folder and the new library which contains the JAXB 1.0 runtime. JAXB 2 ist used by apache cxf for dynamic clients (i need them). So is there a possibility to run the webapps with both libraries? Best regards Alex Caused by: java.lang.LinkageError: You are trying to run JAXB 2.0 runtime but you have old JAXB 1.0 runtime earlier in the classpath. Please remove the JAXB 1.0 runtime for 2.0 runtime to work correctly.

  • activemq-maven-plugin ignore files in classpath?

    - by Oscar Chan
    I have been trying to get activemq-maven-plugin to run activemq with configuration in classpath of the bundle. However, I don't have much luck. It seems that the activemq-maven-plugin just ignore resources (resources/main/conf/activemq.properties) the local bundle. I checked the jar and target/classes and they are built into the right local. I am able to get plugin to run (mvn activemq:run) if I take out the PropertyPlaceholderConfigurer bean in the activemq.xml Did I do anything wrong? Here is the output [INFO] ------------------------------------------------------------------------ [ERROR] BUILD ERROR [INFO] ------------------------------------------------------------------------ [INFO] Failed to start ActiveMQ Broker Embedded error: Could not load properties; nested exception is java.io.FileNotFoundException: class path resource [conf/activemq.properties] cannot be opened because it does not exist [INFO] ------------------------------------------------------------------------ [INFO] For more information, run Maven with the -e switch [INFO] ------------------------------------------------------------------------ [INFO] Total time: 2 seconds [INFO] Finished at: Mon May 03 15:56:05 PDT 2010 [INFO] Final Memory: 11M/79M [INFO] ------------------------------------------------------------------------ Here is the pom.xml, which I specific the plugin to look up activemq.xml via file, that works.

  • Load ActiveX DLL in Internet Explorer with elevated privileges

    - by adum
    I have an ActiveX control that I'm loading with JavaScript in Internet Explorer. It needs to run as medium integrity under UAC in Vista and Win7. This is written in C/C++, compiled in Visual Studio. One way to elevate privileges is to create a broker process that can request a medium integrity level. However, for this project, this is not a practical solution. I really need the ActiveX control itself to run elevated. My question is: what's the easiest way to do this? Can I change the build options on the project to be an exe, and use the COM interprocess connect system to automatically handle the communications, or do I need to be more sophisticated? Do I need to do anything complicated like manually call CreateProcess and make some kind of broker, or can it just work as an ActiveX exe that elevates itself?

  • Running Jetty 7 server in eclipse?

    - by jh314159
    I'm trying to set up Eclipse to run and deploy my projects to a Jetty 7 server (the oldest version available from http://download.eclipse.org/jetty/). I've downloaded Jetty 7 and unpacked it, and I've installed the Jetty plugin from the available server adapters list, but when I try to configure a new Jetty server, the server type list only contains "Jetty 6". If I use this and point it at my server runtime, when I try to start it I get the following error: java.lang.NoClassDefFoundError: org/mortbay/start/Main Caused by: java.lang.ClassNotFoundException: org.mortbay.start.Main at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClassInternal(Unknown Source) Exception in thread "main" I'm guessing I need a different adaptor to start Jetty 7, but I have no idea where to find it.
