• Silverlight 5 App Crashing

  - by bbagfh

  I have a silverlight 5 app that makes some WCF requests. When the silverlight app is hosted locally on an IIS 7.5 server it works fine, but when I run it from a remote IIS6 box there are issues. The app loads fine and presents the login UI. After trying to log in, a couple WCF service calls are made (successfully), but the response causes silverlight to stop responding and the browser eventually asks to kill the non-responsive silverlight app. I am mostly confused because it works fine in IIS 7.5 Note that I am accessing the same WCF services hosted on a remote box in both instances, and both times I am getting successful responses. It is only in IIS6 that the app becomes non-responsive.

• "The provider is not compatible with the version of Oracle client"

  - by psyb0rg

  I just put my asp .net web service on a remote host. The service accesses an oracle db on my local machine. The service worked fine when it was running on localhost but since moving to a remote hos, I get The provider is not compatible with the version of Oracle client at Oracle.DataAccess.Client.OracleInit.Initialize() at Oracle.DataAccess.Client.OracleConnection..cctor() --- End of inner exception stack trace --- at Oracle.DataAccess.Client.OracleConnection..ctor(String connectionString) at.... I know the error is related to the data provider version running on the server/client. In my case, the only dll I referenced in the project was Oracle.DataAccess So how do I go about solving this? Note that I won't be able to change anything on the web host other than my own project. My local machine is running Oracle 11g Thanks.

• Do not compile t4 file

  - by brian b

  Suddenly, after doing a TFS 2010 get, Visual Studio 2010 is attempting to compile my .tt file as if it was c#. Moreover, anytime I set it to "Build Action=None", Build Action gets mysteriously reset to Compile. This is breaking our builds on the desktop. I can get builds to work on the desktop by closing then reopening VS. Our builds on TFS are totally broken because of this. What to do? The template generates a (totally ok) c# file, so I need the project to build. I tried changing the file extension from .tt to .donotbuilddammit but that had no effect.

• Windows Azure Queues, WCF, MSMQ integration

  - by user104295

  Hi there, I have a scenario where I need a desktop console app to communicate with a Windows Azure Queue... the most important thing is that the message is received by the server eventually. Also, the desktop app may be disconnected from the Internet sometimes. In the traditional WCF+MSMQ approach you'd be able to send a message which would be cached in MSMQ until MSMQ could reach the Server's MSMQ and send the message. What's the equivalent when Windows Azure is the server-side? Is it possible for the same approach to be used, where MSMQ just communicates with a Windows Azure Queue rather than an MSMQ on a Windows Server? Maybe Windows Azure Queue is the wrong approach? I have heard about something called message buffer, but don't know what this is (yet!). thanks for your help Kris

• svn cat for git

  - by sanxiyn

  I am looking for the equivalent of svn cat in git. Yes, I am aware that the similar question was asked here. The answer is to use git show rev:path. However, svn cat can be used for the remote repository. That is, I can do svn cat url@rev and get the file from the specified revision of the remote repository, without getting the whole repository. My understanding is that git show only applies to the local repository. A workaround I found is to use gitweb interface to get the blob.

• http_post_data basic authentication?

  - by kristian nissen

  I have a remote service that I need to access, according to the documentation it's restricted using basic authentication and all requests have to be posted (HTTP POST). The documentation contains this code example - VB script: Private Function SendRequest(ByVal Url, ByVal Username, ByVal Password, ByVal Request) Dim XmlHttp Set XmlHttp = CreateObject("MSXML2.XmlHttp") XmlHttp.Open "POST", Url, False, Username, Password XmlHttp.SetRequestHeader "Content-Type", "text/xml" XmlHttp.Send Request Set SendRequest = XmlHttp End Function how can I accomplish this in PHP? When I post data to the remote server it replies: 401 Unauthorized Access which is fine because I'm not posting my user/pass just the data. Bu when I add my user/pass as it's describe here: http://dk.php.net/manual/en/http.request.options.php like this: $res = http_post_data('https://example.com', $data, array( 'Content-Type: "text/xml"', 'httpauth' => base64_encode('user:pass'), 'httpauthtype' => HTTP_AUTH_BASIC ) ); the protocol is https - I get a runtime error in return (it's a .Net service). I have tried it without the base64_encode but with the same result.

• Using emacs across many hosts

  - by mbac32768

  On a daily basis I: use multiple workstations running either Linux, Windows, or MacOS X edit files on additional Linux hosts that are not any of the workstations mentioned above The only common element here is that the internet connects all of these hosts: workstations and servers. I can keep all of the config files in sync on my workstations too and can run an X server on all of them. What's the right way of running emacs? I don't want to sacrifice any features. In my ideal world I can type 'emacs foo.txt' on a remote host and some magic happens via X forwarding to display the file in my workstation's existing emacs session. Non-solutions tramp: when I'm manipulating a remote host an editor is just part of my workflow. I need a terminal open so I can run other commands quickly. tramp is all wrong for this. ncurses emacs: sucks, I want the graphical kind If you don't have a positive answer to my question, please don't just guess. Thanks.

• Git push origin master

  - by user306472

  I posted this question early yesterday, but the thread seems to have died out. For reference, see http://stackoverflow.com/questions/2619117/git-push-origin-master . Here's the low-down: I'm new to git. I just set up an account with github and I followed all their instructions flawlessly until I got to the last command of git push origin master Upon entering this command, I get the error message "fatal: No path specified. See 'man git-pull' for valid url syntax." If I type in git origin show the output I see is origin. If I type in git remote -n show the output is * remote origin URL: [email protected]: HEAD branch: (not queried) Local ref configured for 'git push' (status not queried): (matching) pushes to (matching) Please help me get to the bottom of this.

• Naming selenium grid nodes. Spawning a specific node

  - by ???? ????

  I'm trying to implement a kind of default queues in selenium hub. There is a possibility to specify node's name (actually its environment, smth like "firefox on ubuntu" or "chrome on windows"). Selenium grid itself has a default queue, it works according to 'First In, First Out' principle. But I want to prioritize some of my tasks given to selenium server. I have no possibility to introduce custom queue (seems like there is no API for that), that's why I decided to separate queue's logic from selenium server. I'll only call a specific node with specific name (environment) for example "firefox important node" or smth like that. So, I want to know how to directly tell selenium which node to use for my task? And generally, am I thinking in a right way? Here are my configs: hubConfig.json.erb { "host": null, "port": <%= node[:selenium][:server][:port] %>, "newSessionWaitTimeout": -1, "servlets" : [], "prioritizer": null, "capabilityMatcher": "org.openqa.grid.internal.utils.DefaultCapabilityMatcher", "throwOnCapabilityNotPresent": true, "nodePolling": <%= node[:selenium][:server][:node_polling] %>, "cleanUpCycle": <%= node[:selenium][:server][:cleanup_cycle] %>, "timeout": <%= node[:selenium][:server][:timeout] %>, "browserTimeout": 0, "maxSession": <%= node[:selenium][:server][:max_session] %> } nodeConfig.json.erb { "capabilities": [ { "browserName": "firefox", "maxInstances": 5, "seleniumProtocol": "WebDriver" }, { "browserName": "chrome", "maxInstances": 5, "seleniumProtocol": "WebDriver" }, { "browserName": "phantomjs", "maxInstances": 5, "seleniumProtocol": "WebDriver" } ], "configuration": { "proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy", "maxSession": <%= node[:selenium][:node][:max_session] %>, "port": <%= node[:selenium][:node][:port] %>, "host": "<%= node[:fqdn] %>", "register": true, "registerCycle": <%= node[:selenium][:node][:register_cycle] %>, "hubPort": <%= node[:selenium][:server][:port] %> } } And my Driver class: ... def remote_driver @browser = Watir::Browser.new(:remote, :url => "http://myhub.com:4444/wd/hub", :http_client => client, :desired_capabilities => capabilities ) end def capabilities Selenium::WebDriver::Remote::Capabilities.send( "firefox", :javascript_enabled => true, :css_selectors_enabled => true, :takes_screenshot => true ) end def client client = Selenium::WebDriver::Remote::Http::Default.new client.timeout = 360 client end ... I still don't know how to use specified node for my task. If I try to start a driver adding :name => "firefox important node" and extend nodeConfig.json.erb's configuration with environments: - name: "firefox important node" browser: "*firefox" - name: "Firefox36 on Linux" browser: "*firefox" selenium just starts random firefox browser on a random node. How can I control it?

• VB.NET function that takes other functions as a parameter, and executes them

  - by rob

  Hello, Is there a way in vb.net to create a sub/function that will take as an argument some kind of pointer to another function, and allow this new sub/function to execute the passed function? What I have are 10-12 xml-rpc functions I am calling against a remote server. Each of these functions has different argument lists (one takes 1 string, another might take 3 strings and one int, etc). All of them return an object. As I am calling these, it seems like it should be able to be factored better. For instance, everytime I call any of these functions, I want to test the return value for a session drop, and do something to try and reconnect to the remote system, etc. Using .net 3.5 Thanks! -R

• How do I create a Launcher in Ubuntu 9.1 that runs a shell script?

  - by mkelley33

  Here's my situation: New to Ubuntu (just nstalled 9.10 Karmic Koala 64 bit) Purpose: to easily run PyCharm without too much typing (ie. cd... ./pycharm.sh) Want to create desktop Launcher instead of terminal & typing (without resorting to the "Run in Terminal" option) Tried to create Launcher to executes .sh script in Document directory Right-clicked Desktop Create Launcher a. Type == Application; Browse [insert absolute path to .sh script]; no luck b. Type == Application in Terminal; Browse ...ditto I'm open to any other alternatives that involve as little typing as possible. I would like to just start Ubuntu, click Launcher icons, and have terminals spring to life, running the intended scripts. Crazy? No. Lazy? Probably. Productive? Hopefully :)

• Javascript callback on blackberry

  - by Jeff

  I'm working on a mobile project, and I have a script that is dynamically generated on the backend and then appended to the document (the html page). Desktop browsers seem to append the script correctly and call any functions in the script, however, I can't get this to happen on Blackberry phones. I know that the script is being appending because I can alert it after I append it. I just can get it to call the function in the script. For example, if I have code like this: var scriptText = document.createElement('script'); scriptText.type = 'text/javascript'; scriptText.id = 'thisScript'; scriptText.innerHTML = 'alert("hello");'; document.getElementById('idName').appendChild(scriptText); alert(document.getElementById('thisScript')); //Alerts the script element. This will alert 'hello' in desktop browsers and even the iPhone/iPodTouch, but not BlackBerry's. Anyone have any idea why? Or if there's a fix/hack?

• Software Requirement Specifications for Web Applications

  - by illuminatedtiger

  Hi guys, I'm looking for some guidance/books to read when it comes to creating a software requirement specification for a web application. For inspiration I have read some spec documents for desktop based applications. The documents I have read capture a systems functional requirements in use cases which tend to be rather data oriented with use cases centered around the various CRUD operations the application is intended to perform. I like this structure however I'm finding it rather difficult to marry it to what my web application needs to do, mostly reading data as opposed to manipulating it. I've had a go at writing some use cases however they all tend to boil down to "Search for item", "Change view of search results" or "User selects facet to refine search results". This doesn't sound quite right to me and makes me wonder if I'm going about this the right way. Are there planning differences between web based and desktop based applications?

• Developing Qt applications in Unix systems using Qt Creator

  - by Jake Petroules

  I'm developing a Qt application in Linux using Qt Creator (2.1 RC). I've created 2 projects, and used the wizard to add the library project to the application project. However when I run it, I receive the error: /home/jakepetroules/silverlock/silverlock-build-desktop/desktop/silverlock: error while loading shared libraries: libsilverlocklib.so.1: cannot open shared object file: No such file or directory Is there some qmake variable I can set so that Qt Creator will set up the environment properly to run? It's quite annoying to have to copy all the files to another directory with a launcher script just to be able to test the build. On Windows it works perfectly - Qt Creator automatically adds the directories containing the DLLs to the PATH when it runs your application (where running it from Explorer would say DLL not found). Mac OS X is even worse, having to run install_name_tool on everything... So how can I set up my qmake files so everything works right from the run button in Qt Creator? Kind of hard to debug without this ability, too.

• Tomcat fails on first request in combination with jsvc

  - by Roalt

  I have a web application where the first request may take a few seconds as some singletons are initialised. I've used the mod_proxy and jsvc construction mentioned in this question and described on this page to connect apache with tomcat (data is served via SSL) For the sample Tomcat application, everything works as it should. However, when using my application I get the following error in my apache log: [Wed Feb 10 09:48:29 2010] [error] [client 130.12.1.26] (70014)End of file found: proxy: error reading status line from remote server localhost [Wed Feb 10 09:48:29 2010] [error] [client 130.12.1.26] proxy: Error reading from remote server returned by /MyWebApp/MyWebApp.faces and I get the following error in my tomcat output: 10/02/2010 09:48:29 9947 jsvc.exec error: Service exit with a return value of 1 I'm not an expert on this so I would like to know what's the cause of the problem and where I should look for an answer?

• Push origin master error on new repository.

  - by thaiyoshi

  I just started using git with github. I followed their instructions and ran into errors on the last step. I'm checking in an existing directory that isn't currently source-controlled (project about a week old). Other than that, my use case should be pretty run of the mill. Here's what's happening: $ git push origin master error: src refspec master does not match any. fatal: The remote end hung up unexpectedly error: failed to push some refs to '[email protected]:{username}/{projectname}.git' Github's instructions: Global setup: Download and install Git git config --global user.name "Your Name" git config --global user.email {username}@gmail.com Next steps: mkdir projectname cd projectname git init touch README git add README git commit -m 'first commit' git remote add origin [email protected]:{username}/{projectname}.git git push origin master

• Can you use Github App with Beanstalk?

  - by mikemick

  Being new to Git, I wanted to use a GUI (Windows based) and preferred the Github App. However, I would like to integrate this site with a Beanstalkapp account. I'm pretty sure this is possible, but I can't figure it out. Inside of the Github app, I navigate to my repository. When I choose "Tools Settings...", I place the Git Clone URL for the repository provided by Beanstalk into the "Primary Remote (origin)" field in my Github app. Now when I click "Publish" (which says "Click to publish this branch to server" when I hover over it) it changes to "Publishing...". After a few seconds, I get this error: server failure The remote server disconnected. Try again later, or if this persists, contact [email protected] I am pretty sure I set the SSH keys up properly (never done this before). I added the key to both the Beanstalkapp and my Github web account.

• Build Systems for PHP Web Apps

  - by macinjosh

  I want to start automating more of my web development process so I'm looking for a build system. I write mostly PHP apps on Mac OS X and deploy Linux servers over FTP. A lot of my clients have basic hosting providers so shell access to their servers is typically not available, however remote MySQL access is usually present. Here is what I want to do with a build system: When Building: Lint JavaScript Files Validate CSS Files Validate HTML Files Minify and concatenate JS and CSS files Verify PHP Syntax Set Debug/Production flags When Deploying Checkout latest version from SVN Run build process Upload files to server via FTP Run SQL scripts on remote DB I realize this is a lot of work to automate but I think it would be worth it. So what is the best way to start down this path? Is there a system that can handle builds and deploys, or should I search for separate solutions? What systems would you recommend?

• Cross-database transactions from one SP

  - by Michael Bray

  I need to update multiple databases with a few simple SQL statement. The databases are configurared in SQL using 'Linked Servers', and the SQL versions are mixed (SQL 2008, SQL 2005, and SQL 2000). I intend to write a stored procedure in one of the databases, but I would like to do so using a transaction to make sure that each database gets updated consistently. Which of the following is the most accurate: Will a single BEGIN/COMMIT TRANSACTION work to guarantee that all statements across all databases are successful? Will I need multiple BEGIN TRANSACTIONS for each individual set of commands on a database? Are transactions even supported when updating remote databases? I would need to execute a remote SP with embedded transaction support. Note that I don't care about any kind of cross-database referential integrity; I'm just trying to update multiple databases at the same time from a single stored procedure if possible. Any other suggestions are welcome as well. Thanks!

• rake task can't access rails.cache

  - by mark

  Hi I want to call a rake task from a cron job that stores remote weather data in the rails cache. However, I must be doing something pretty wrong here because I cannot find any solution through countless fruitless searches. Say I define and call this task namespace :weather do desc "Store weather from remote source to cache" task :cache do Rails.cache.write('weather_data', Date.today) end end I get the error Anonymous modules have no name to be referenced by Which leads me to believe the rails cache isn't available. Outputting Rails.class from the rake file gives me Module but Rails.cache.class again returns the above error. Do I need to include something here? Am I just hopeless at internet? :) Thanks in advance.

• help finding a hosing company with unixODBC and FreeTDS support

  - by patrick

  I need to find a hosting company that provides a LAMP stack, the P being PHP. Finding that is pretty easy, but I have a further requirement of unixODBC and FreeTDS or some equilant. The project will require a remote connection to a Microsoft SQL 2005 database. Most of the project will use a local MySQL database but it also requires data from a remote MS SQL 2005 database. In my reading it looks like I'll need unixODBC and FreeTDS installed on the server to make that connection. So far I've been unable to find a shared host that provides these. Can anyone suggest or use a host that might work? The project has budget limits so we we're hoping to find a shared host.

• Would Mercurial help me work from 2 PCs?

  - by rikh

  I currently use Perforce for source control, but want to start working on the code from 2 different PCs at the same time (desktop and laptop). The laptop would not be able to access the perforce server very often, which makes Perforce a poor choice in this setup. Distributed source control tools like Mercurial seem better suited to the task, but I am still not clear if this would work or not. Does anyone have any experience of using Mercurial to work on 2 machines at once (eg desktop in the week, laptop in evening and weekends). Does it help, or is it still a pain the butt keeping everything in sync and knowing what is going on.
