  • Getting closure-compiler and Node.js to play nice

    - by bukzor
    Are there any projects that used node.js and closure-compiler (CC for short) together? The official CC recommendation is to compile all code for an application together, but when I compile some simple node.js code which contains a require("./MyLib.js"), that line is put directly into the output, but it doesn't make any sense in that context. I see a few options: Code the entire application as a single file. This solves the problem by avoiding it, but is bad for maintenance. Assume that all files will be concatenated before execution. Again this avoids the problem, but makes it harder to implement a un-compiled debug mode. I'd like to get CC to "understand" the node.js require() function, but that probably can't be done without editing the compiler itself, can it?

  • Passing HttpFileCollectionBase to the Business Layer - Bad?

    - by Terry_Brown
    hopefully there's an easy solution to this one. I have my MVC2 project which allows uploads of files on certain forms. I'm trying to keep my controllers lean, and handle the processing within the business layer of this sort of thing. That said, HttpFileCollectionBase is obviously in the System.Web assembly. Ideally I want to call to something like: UserService.SaveEvidenceFiles(MyUser user, HttpFileCollectionBase files); or something similar and have my business layer handle the logic of how and where these things are saved. But, it feels a little icky to have my models layer with a reference to System.Web in terms of separation of concerns etc. So, we have (that I'm aware of) a few options: the web project handling this, and my controllers getting fatter mapping the HttpFileCollectionBase to something my business layer likes passing the collection through, and accepting that I reference System.Web from my business project Would love some feedback here on best practice approaches to this sort of thing - even if not specifically within the context of the above.

  • Running a Java process in Windows even after the user is logged out

    - by Mani
    I have a batch file that starts a Java process in a Windows 2003 server. As per the security policy, the users of that machine are logged off forcefully, if the user is inactive for a certain period of time. The problem is that when the user is logged out, the process also dies. I scheduled a new task (Control Panel - Scheduled Tasks) and selected the option of 'When my computer starts' and gave the user account details there. But it doesn't seem to have any effect, the user is still logged out and the process dies. Is a reboot necessary to make this change effective? And after the reboot, will I achieve what I'm expecting (keeping the process alive)? Alternatively, will running this process as a Windows Service solve the problem? If so, can you please let me know how I can make a Java program or a batch file to run as a Windows Service? I would prefer not to use any other third party tools or libraries. Thanks

  • How to preload local javascript everytime a new tab or page is opened?

    - by Klerk
    I would like to autoload a local javascript file, everytime a new page/tab is opened in a browser. I tried the bookmarklet approach, but it gets tiresome as the button needs to be pressed everytime a new page/tab is opened. Chrome extensions also seem to work along the same lines (where you have to press an icon to run the js). Googling for javascript and preload seems to return everything except what I am looking for. Is there a browser indepent way of autoloading (no user action required) a local js file? If not, any browser specific info to do this would be appreciated (even if they mean reducing security by turning off required options). Thanks!

  • Rails3 and safe nl2br !

    - by arkannia
    Hi, I have a system for the users to be able to post comments. The comments are grasped into a textarea. My problem is to format the comments with br tag to replace \n In fact, i could do something like that s.gsub(/\n/, '<br />') But the xss protection including in rails escapes br tags. So i could do this s.gsub(/\n/, '<br />').html_safe But then, all the tags are accepted even script.... causing a big security problem So my question is : how to format text with br safely ? Thanks EDIT: For now, i have add this def sanitaze self.gsub(/(<.*?>)/, '') end def nl2br self.sanitaze.gsub(/\n/, '<br />').html_safe end

  • buffer overflow with boost::program_options

    - by f4
    Hello, I have a problem using boost:program_options this simple program, copy-pasted from boosts' documentation : #include <boost/program_options.hpp> int main( int argc, char** argv ) { namespace po = boost::program_options; po::options_description desc("Allowed options"); desc.add_options() ("help", "produce help message") ("compression", po::value<int>(), "set compression level") ; return 0; } fails with a buffer overflow. I have activated the "buffer security switch", and when I run it I get an "unknown exception (0xc0000409)" when I step over the line desc.add_options()... I use Visual Studio 2005 and boost 1.43.0. By the way it does run if I deactivate the switch but I don't feel comfortable doing so... unless it's possible to deactivate it locally. So do you have a solution to this problem? EDIT I found the problem I was linking against libboost_program_options-vc80-mt.lib which wasn't the good library.

  • Best solution for language documentation.

    - by Simone Margaritelli
    I'm developing a new object oriented scripting language and the project itself is quite ready for audience now, so i'm starting to think about a serious (not as "drafty" as it is right now) way of document its grammar, functions from standard library and standard library classes. I've looked a bit around and almost every language hash its own web application for the documentation, Python uses Sphinx for instance. Which is the best PHP (don't have the time/will to install mod_who_knows_what on my server) application to accomplish this? I've used mediawiki a bit but i found its tag system a little bit hard to use in this context. Thanks for your answers.

  • Silverlight 3 and System.ServiceProcess - Doesn't allow the reference to be added.

    - by Brad8118
    I'm trying to write a program that can stop and start services using SilverLight 3 and VS2010. I can't add the reference to the System.ServiceProcess dll. C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.ServiceProcess.dll 1st why? - It it just a security precaution? 2- Is there a work around? Does SilverLight have a different library that I can use to start and stop services. Also note that this is a desktop application and not a web app. It will be sitting on my desktop to toggle services on and off.

  • Replacing delimiter characters in file path

    - by salvationishere
    I'm developing a C# web application in VS 2008. I let the user select an input file and then I store the file path in a string variable. However, it stores this path as "C:\\folder\\...". So my question is how do I convert this file path into single "\"? To clarify more, this is my code in context. Currently it is entering the If Directory does not Exist section. protected void btnAppend_Click(object sender, EventArgs e) { string fullpath = Page.Request.PhysicalPath; fullpath.Replace('\\', '\'); if (!Directory.Exists(fullpath)) { string msg = "<h1>The upload path doesn't exist: {0}</h1>";

  • PHP CHECKBOX Array Issue

    - by Val
    I have a list of checkboxes like you would see in most email clients (You tick a box press delete then it deletes an email). <input type="checkbox" value="yes" name="box[]" /> The problem stands here ... print_r($_POST['box']);//Returns nothing at all ... var_dump($_POST['box']);// returns null... I was reading something about register globals that php5 has turned it off for security reason. Does anyone know what my options are ?

  • Programatically Start OSGi (Equinox)?

    - by javamonkey79
    I'd like to be able to easily start an OSGi framework (preferably Equinox) and load up any bundles listed in my pom from a java main. Is this possible? If so, how? It seems like the pax tools would do this, but I can't seem to find any documentation indicating such. I know I can start up Equinox like so: BundleContext context = EclipseStarter.startup( ( new String[] { "-console" } ), null ); But I'd like to do more - like I said: load more bundles in, maybe start some services, etc.

  • "SQL Server does not exist or access denied." upon VB.Net Deployment

    - by JasonMHirst
    Have built a small VB.Net app in VS2010. The connection string to the SQL Server is as follows: <connectionStrings> <add name="IWSR_DataDownloadWizard.My.MySettings.sqlConnection" connectionString="Provider=SQLOLEDB.1;Data Source=SQLServer;Integrated Security=SSPI;Initial Catalog=IWSROL" providerName="System.Data.OleDb" /> </connectionStrings> Within the VS2010 environment AND on my machine, the connection works perfectly, however when I deploy to clients I get an error message of: [DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied. I've tried to search the net for solutions, have seen a few instances of people saying to NOT use the Server Name but the IP Address instead (this doesn't work) and some saying to remove the "Provider=SQLOLEDB.1", again this doesn't work. Can anyone suggest a solution please? Further information: Development System is Windows7 using VS2010 Deployment systems are a combination of Windows XP, Windows 2000 and Windows 7 SQL Server is SQL2000 (soon to be SQL2005). TIA

  • Python Game using pyGame with Window Menu elements

    - by Zoja
    Here's the deal. I'm trying to write an arkanoid clone game and the thing is that I need a window menu like you get in pyGTK. For example File-(Open/Save/Exit) .. something like that and opening an "about" context where the author should be written. I'm already using pyGame for writting the game logic. I've tried pgu to write the GUI but that doesn't help me, altough it has those menu elements I'm taking about, you can't include the screen of the game in it's container. Does anybody know how to include such window menus with the usage of pyGame ?

  • PHP - Concatenating objects and casting to string - bad idea?

    - by franko75
    Is it bad practice to concatenate objects when used in this context: $this->template->head .= new View('custom_javascript') This is the way i normally add extra css/js stuff to specific pages. I use an MVC structure where my basic html template has a $head variable which I set in my main Website_controller. I have used this approach for a while as it means I can just add bits and pieces of css/js stuff from whichever page/controller needs it. But having come across a problem in PHP 5.1.6 where the above code results in "Object ID #24", the result of toString() not being called i think, I am rethinking whether i should just fix this to work in PHP 5.1.6 or if i should rethink this approach in general. Any pointers appreciated!

  • Set a js variable in a html include

    - by user102533
    I have a ASP.NET page that uses the include method for header. I am adding a JS variable that I access from JS functions In head.htm <script language="javascript" type="text/javascript"> var render=<%= RenderProperty %>; </script> The RenderProperty is a method in the base page class (a .cs file that inherits from System.Web.UI.Page) It looks something like this: private bool _renderProp = false; public bool RenderProperty { get { return _renderProp; } set { _renderProp = value; } } On a page by page basis, I set the RenderProperty in the Page_Load of a aspx page protected void Page_Load(object sender, EventArgs e) { RenderProperty = true; } I get a compile time error that says: The name 'RenderProperty' does not exist in the current context C:\...\head.htm

  • Screening (multi)collinearity in a reggresion model

    - by aL3xa
    I hope that this one is not going to be "ask-and-answer" question... here goes: (multi)collinearity refers to extremely high correlations between predictors in the regression model. How to cure them... well, sometimes you don't need to "cure" collinearity, since it doesn't affect regression model itself, but interpretation of an effect of individual predictors. One way to spot collinearity is to put each predictor as a dependent variable, and other predictors as independent variables, determine R2, and if it's larger than .9 (or .95), we can consider predictor redundant. This is one "method"... what about other approaches? Some of them are time consuming, like excluding predictors from model and watching for b-coefficient changes - they should be noticeably different. Of course, we must always bare in mind specific context/goal of analysis... Sometimes, only remedy is to repeat a research, but right now, I'm interested in various ways of screening redundant predictors when (multi)collinearity occurs in a regression model.

  • Access Validation Rule Violations on Append Query

    - by Jacques Tardie
    I'm recieving the following error on trying to run an append query in access. Microsoft Office Access set .... and it didnt't add... 779280 records(s) due to validation rule violations. If I choose to run the query anyways, nothing actually happens. To give some context, I'm simply trying to copy a populated field, consisting of values similar to "16-2009-02, 34-2010-02, et cetera" to another currently unpopulated field. The fields themselves have no set validation rules, and both have the standard text field options. I'm hoping to be able to simply remove those hyphens, and fix the issue. But I guess that's what I'm not sure about, are those hyphens actually a problem? Running SP3 w/ Access 2003. Thanks in advance!

  • Operator Overloading with C# Extension Methods

    - by Blinky
    I'm attempting to use extension methods to add an operater overload to the C# StringBuilder class. Specifically, given StringBuilder sb, I'd like sb += "text" to become equivalent to sb.Append("text"); Here's the syntax for creating an extension method for StringBuilder: public static class sbExtensions { public static StringBuilder blah(this StringBuilder sb) { return sb; } } It successfully adds the "blah" extension method to the StringBuilder. Unfortunately, operator overloading does not seem to work: public static class sbExtensions { public static StringBuilder operator +(this StringBuilder sb, string s) { return sb.Append(s); } } Among other issues, the keyword 'this' is not allowed in this context. Are adding operator overloads via extension methods possible? If so, what's the proper way to go about it?

  • GKSession sendDataToAllPeers including sendee?

    - by Typeoneerror
    I've got a number of devices connected over wifi using GameKit. I have a simple UIAlertView popping up when peers receive data. All but the sendee show this alert view when data is sent, so I'm wondering if that's a bug in my app or if that's expected behavior. Should call a method manually at the same on the sendee device? For example, if I wanted to send a "GameStart" packet to the 4 phones, the peers would call startGame: in the receiveData:fromPeer:inSession:context: method when it receives that packet and the sendee would just sendData and call startGame: on itself. Does that sound right or is there a way to include the sendee in the sendData list so that it responds exactly the same as all connected peers?

  • Why is it not possible to call RegFree COM and .NET from the VB IDE (VB6 & VBA)?

    - by DangerMouse
    Hi I have an example project with works when called from compiled VB6 but not from the IDE or from Excel's VBE. There are 3 DLLs QA.DLL, QB.DLL, QAW.DLL. QA is written in C#.NET, QB and QAW are written in VB6. QAW is a COM wrapper of QA. In the calling code I create an Activation Context and load a manifest file. All works fine from the exe created with VB6, but not in debug mode in VB6 or in Excel's VBA. I have the full example in zip. Any ideas what it is that is different about the IDE call and why it doesn't work? Many Thx -- DM

  • Flex: How can I use the @ContextRoot in a Button or LinkButton

    - by Dave Meurer
    I'm trying to create a button that will simply link back to the context root. I noticed flex has a @ContextRoot attribute that appears to work only in certain cases. For example, if I try to use it in the following mxml: <mx:Button label="Back to Root" click="navigateToURL(new URLRequest(@ContextRoot()), '_parent')"/> I get the following error: Error: Attributes are not callable. I can't seem to find this technique explained anywhere, is there another way? Thanks for the help! Dave

  • Other SecurityManager implementations available?

    - by mhaller
    Is there any other implementation (e.g. in an OSS project) of a Java SecurityManager available which has more features than the one in the JDK? I'm looking for features like configurable at runtime policies updateable at runtime, read from other data sources than a security.policy file Thread-aware, e.g. different policies per Thread Higher-level policies, e.g. "Disable network functions, but allow JDBC traffic" Common predefined policies, e.g. "Allow read-access to usual system properties like file.encoding or line.separator, but disallow read-access to user.home" Monitoring and audit trace logging, e.g. "Log all file access, log all network access going NOT to knownhost.example.org" Blocking jobs "requesting" a permission until an administrator grants permission, letting the thread/job continue ... I'm pretty sure that application servers (at least the commercial ones) have their own SecurityManager implementation or at least their own policy configuration. I'm wondering if there is any free project with similar requirements.

  • Can a signed Java Applet/Web Start manipulate content in a cross-site IFRAME?

    - by etoleb
    Is it possible for a signed Java Applet or Web Start app to write to the DOM of an IFRAME under a different domain? Does the fact that they're a signed applet/javaws allow them to ignore browsers' standard cross-browser security? If this does work, how well is it supported across the major browsers? Thanks! EDIT: My motivation is to add a browser plugin-like tool to third-party websites I don't control. It's not required that I use Java at all---any ideas or suggestions are encouraged.
