• Node.JS Server Cuts Off Frequently?

  - by aherrick

  I have a Node JS Server where I am using Socket.IO to stream content to the browser. It works great for about 45 minutes or so of streaming, then it will usually cut out. There are no "errors" reported in the terminal and the Node server acts like it is in, however the page I am serving clearly stops working. What are my options for trying to get to the bottom of this? Could this be a configuration issue with Node/Socket.IO? is there any basic error logging you would recommend I setup?

• Getting 0x80131902 when calling COM+ component

  - by Kyle W

  I created a COM+ component in .Net. It needs to use a configuration file, so I've created a directory with an application.manifest and application.config file and set that as the Application Root Directory. Now when I try to create an instance of that object, I get the following HRESULT: 0x80131902. I can't seem to find exactly what this means, except that there is a problem loading the app-domain. If I don't set the Application Root Directory, it loads just fine (but doesn't have access to the config).

• Error when accessing IIS 7 server variable from ASP.Net MVC

  - by StephSpr

  I have an ASP.Net MVC application which works fine on IIS 6.0 / Windows Server 2003. When installed on IIS 7.5 / Windows Server 2008 (integrated mode), it works but when the application attempts to generate an URL, it runs into the following error: [NullReferenceException: Object reference not set to an instance of an object.] System.Web.HttpServerVarsCollection.Get(String name) +10960764 System.Web.Mvc.PathHelpers.GenerateClientUrlInternal(HttpContextBase httpContext, String contentPath) +345 System.Web.Mvc.PathHelpers.GenerateClientUrl(HttpContextBase httpContext, String contentPath) +80 System.Web.Mvc.UrlHelper.GenerateUrl(String routeName, String actionName, String controllerName, RouteValueDictionary routeValues, RouteCollection routeCollection, RequestContext requestContext, Boolean includeImplicitMvcValues) +256 System.Web.Mvc.UrlHelper.Action(String actionName, String controllerName, RouteValueDictionary routeValues) +36 It looks like IIS7 fails to return the server name. There should be a configuration to set, but I couldn't find anything like that. Do you have any idea to fix this issue ? Thanks,

• gVim and multiple programming languages

  - by Abhi

  My day job involves coding with Perl. At home I play around with Python and Erlang. For Perl I want to indent my code with two spaces. Whereas for Python the standard is 4. Also I have some key bindings to open function declarations which I would like to use with all programming languages. How can this be achieved in gVim? As in, is there a way to maintain a configuration file for each programming language or something of that sort?

• C# 2D Vector Graphics Game using DirectX or OpenGL?

  - by Brian

  Hey Guys, So it has been a while since I have done any game programming in C#, but I have had a recent bug to get back into it, and I wanted some opinions on what configuration I should use. I wanted to use C# as that is what I use for work, and have become vary familiar with. I have worked with both DirectX and OpenGL in the past, but mostly in 3D, but now I am interested in writing a 2D game with all vector graphics, something that resembles the look of Geometry Wars or the old Star Wars arcade game. Key points I am interested in: • Ease of use/implementation. • Easy on memory. (I plan on having a lot going on at once) • Looks good, I don't want curve to look pixelated. • Maybe some nice effects like glow or particle. I am open to any and all suggestions, maybe even something I have not thought of... Thanks in advance!

• What are the main reasons against the Windows Registry?

  - by dbemerlin

  If i want to develop a registry-like System for Linux, which Windows Registry design failures should i avoid? Which features would be absolutely necessary? What are the main concerns (security, ease-of-configuration, ...)? I think the Windows Registry was not a bad idea, just the implementation didn't fullfill the promises. A common place for configurations including for example apache config, database config or mail server config wouldn't be a bad idea and might improve maintainability, especially if it has options for (protected) remote access. I once worked on a kernel based solution but stopped because others said that registries are useless (because the windows registry is)... what do you think?

• mdi child forms slow to draw when visibility changed

  - by dandan78

  My application has the following UI configuration: The main form is an MDI container. Its child forms are attached to a tabstrip. Each user has his set of child forms. Depending on the active user, only that user's child forms are displayed, together with tabs. This is achieved by going through the main form's MdiChildren and setting their Visible property to false/true depending on the active user. This has two undesired effects. One is that every child form gets redrawn in succession, which is ugly and slow. The other is that for some reason the forms go from maximized to normal, effectively undocking them from the main form. Is there any way to display just one of the child forms, such as the one the user was previously looking at, and get the others to stay in the background? The maximize/normal thing is not that big a deal because I can maximize them again manually.

• How to find/display the Upload File limits on IIS with ASP.NET?

  - by NVRAM

  I have a web service on which the end users will be uploading ZIP archives that can be very large (one test file is over 200MB). I'd like to handle oversized files proactively and size-limited upload failures gracefully. Since the web app will be deployed on customers' machines, so I cannot easily ensure that the configuration matches any fixed size. I've documented how to use the appcmd command for them to set the requestLimits.maxAllowedContentLength value beyond the 30MB default. But I'd like to handle it in the web app; I'm hoping for two things: To show the current limit on the page where they initiate the file upload, something along the lines of: Each file upload is limited to 15MB. If your archive is larger, (etc., etc., etc.) To give a meaningful error when that size is exceeded. Currently, it takes a long time for the data to be sent, and then I see a misleading 404 page. Any thoughts?

• Maven best practice for generating artifacts for multiple environments [prod, test, dev] with CI/Hud

  - by jaguard

  I have a project that need to be deployed into multiple environments (prod, test, dev). The main differences mainly consist in configuration properties/files. My idea was to use profiles and overlays to copy/configure the specialized output. But I'm stuck into if I have to generate multiple artifacts with specialized classifiers (ex: "my-app-1.0-prod.zip/jar", "my-app-1.0-dev.zip/jar") or should I create multiple projects, one project for every environment ?! Should I use maven-assembly-plugin to generate multiple artifacts for every environment ? Anyway, I'll need to generate all them at once so it seams that the profiles does not fit ... still puzzled :( Any hints/examples/links will be more than welcomed. As a side issue, I'm also wondering how to achieve this in a CI Hudson/Bamboo to generate and deploy these generated artifacts for all the environments, to their proper servers (ex: using SCP Hudson plugin) ?

• wamp magento no admin page

  - by Mortgage Ms

  I have a live magento website hosted in Bluehost, I just installed wamp and tried to clone the live website to local wamp server. After some configuration changed from live server to local, the site is working with no problem, however, there is no admin page! If I go to localhost/magento/admin, it takes me to 404 page and throw error: The requested URL /magento/admin was not found on this server. How do I fix this? Thanks lots.

• WCF REST Service not working - not showing anything

  - by casperrawr

  I've been scratching my head for the past 20 hrs or so trying to figure out what is wrong with my rudimentary WCF app but with absolutely no luck :( I was following this tutorial: http://www.c-sharpcorner.com/UploadFile/dhananjaycoder/RESTEnabledService05122009034907AM/RESTEnabledService.aspx and for some reason the WCF is showing a blank page. I checked IIS, reinstalled .NET 4.0, cleaned and redid .svn handlers, tried on different test servers...and still, nada. Do you know what might be wrong with the configuration? I figured the code is simple enough (essentially the same as the page I posted) so it can't be the code itself...right? any help will be appreciate :)

• How can I create an ODBC connection to SAS?

  - by Chris B.

  I'm writing a program that needs to access SAS data. I've downloaded the ODBC drivers for SAS and installed them, but I need to be able to create ODBC connections on the fly, programmatically. The following code (in Python) seems like it should work: import ctypes ODBC_ADD_DSN = 1 def add_dsn(name, driver, **kw): nul, attrib = chr(0), [] kw['DSN'] = name for attr, val in kw.iteritems(): attrib.append('%s=%s' % (attr, val)) return ctypes.windll.ODBCCP32.SQLConfigDataSource(0, ODBC_ADD_DSN, driver, nul.join(attrib)) == 1 print add_dsn('SAS Test', 'SAS', description = 'Testing SAS') But it pops up the SAS ODBC configuration dialog, sets the datasource name, and waits for the user to enter the information and dismiss the dialog. How can I avoid that?

• Updates to Wordpress theme template/stylesheet are not reflected when a file is edited

  - by Bryan

  I am developing a theme in Wordpress. I have an issue where updates to my stylesheet (style.css) are not being reflected in the browser after FTPing a new version of the file to the server. Edits will only show up in the browser after waiting a long time, (15+ minutes). I have tried all the things mentioned here, which have not worked. These include: Making sure no caching plugins are installed in Wordpress Clearing the browser cache Trying from a different browser Making sure I am editing and accessing the correct file Checking webhost configuration panel for a caching plugin Something seems to be caching the stylesheet but I'm not sure how this might be so.

• $HOME git repo (selectively) to github?

  - by user428502

  I keep many files in my home directory under git. Important dotfiles, my thesis, etc. I want to push certain files to github, e.g., my emacs configuration, to share. Obviously, I don't want to push the entire repo. Are submodules the way to go? My first thought is to make a directory ~/github/emacs, and rsync selective files here, then add a submodule under that directory, pointing to github, to push. Is this a good idea, or is there a better way? (I don't want my local git repo storing all files to get muddled up with this stuff, though.)

• Config file format

  - by Felics

  Hello, does anyone knows a file format for configuration files easy to read by humans? I want to have something like tag = value where value may be: String Number(int or float) Boolean(true/false) Array(of String values, Number values, Boolean values) Another structure(it will be more clear what I mean in the fallowing example) Now I use something like this: IntTag=1 FloatTag=1.1 StringTag="a string" BoolTag=true ArrayTag1=[1 2 3] ArrayTag2=[1.1 2.1 3.1] ArrayTag3=["str1" "str2" "str3"] StructTag= { NestedTag1=1 NestedTag2="str1" } and so on. Parsing is easy but for large files I find it hard to read/edit in text editors. I don't like xml for the same reason, it's hard to read. INI does not support nesting and I want to be able to nest tags. I also don't want a complicated format because I will use limited kind of values as I mentioned above. Thanks for any help.

• SVN - ignoring files already in repository

  - by Alex

  I have a configuration file in my project which needs to be in the repository (so new developers get it when they checkout the project). Each developer might change some values in the file locally - these changes should not be committed and I don't want them showing in the synchronization menu (I'm using eclipse and subversive if it matters). Note that I can't just set the svn:ignore property since it only works on files that aren't under version control - but I do want to keep a base version of the file in the repository. How can I avoid the file showing in synchronization without deleting it from repository? EDIT: A better description - what I actually need is to be able to set a "read-only" property on the config file, so it can't be changed in the repository as long as the property is on. Do you know anything like this? Thanks

• App.config path not correctly interpreted by ASP.NET Application

  - by seragu05

  Hello everyone ! I'm working on a very old project (2000) in VB6 which was "modernized" and upgraded to VB.NET 3.5. I've centralized every old INI configuration file into one MainApp.config, which is referenced by the app.config of every component. There's an VB ASP.NET website in the solution, which uses DLL components, which are looking into app.config for parameters like, say, error log directory, etc. I've deployed the site on my dev. server (Windows 2008 Server w/ IIS 7.0) into the D:\WebSite\ directory. Problem: When running the site, an error occurs. A DLL is looking into app.config for the parameter RepertoireErreur which has the value .\Erreurs\ Instead of returning D:\WebSite\Erreurs\ it returns c:\windows\system32\inetsrv\.\Erreurs\ which doesn't contain the Erreurs directory. Boom. Error. Does anyone have ever encountered the same problem ? Is there a solution ? Thanks,

• Do you use Phing?

  - by Sam McAfee

  Does anyone use Phing to deploy PHP applications, and if so how do you use it? We currently have a hand-written "setup" script that we run whenever we deploy a new instance of our project. We just checkout from SVN and run it. It sets some basic configuration variables, installs or reloads the database, and generates a v-host for the site instance. I have often thought that maybe we should be using Phing. I haven't used ant much, so I don't have a real sense of what Phing is supposed to do other than script the copying of files from one place to another much as our setup script does. What are some more advanced uses that you can give examples of to help me understand why we would or would not want to integrate Phing into our process.

• Detect all depencies of an application

  - by Ian

  Hi All, I am in the process of "detecting" (more like listing down) all of the dependencies of our application. Currently, I am using depends.exe (Dependency Walker) to detect all of the file dependencies. I was actually able to get pass all the error messages about missing files and dependencies. However, when launching the app, all I get is a crash without any messages at all. On a "working" configuration/system, I was able to launch this app successfully. Killing a certain service will produce the "crashing" behavior. This leads me to the conclusion that SOMETHING on this service is needed by the App and this service is a dependency. However, depends.exe will not be able to "detect" this dependency. My question is: Is there an application that can programmatically detect dependencies such as Database and Services? Thanks!

• How to add folder to assembly search path at runtime in .NET?

  - by Valery Tydykov

  My DLLs are loaded by a third-party application, which we can not customize. My assemblies have to be located in their own folder. I can not put them into GAC (my application has a requirement to be deployed using XCOPY). When the root DLL tries to load resource or type from another DLL (in the same folder), the loading fails (FileNotFound). Is it possible to add the folder where my DLLs are located to the assembly search path programmatically (from the root DLL)? I am not allowed to change the configuration files of the application.
