• How does the same origin policy apply to IP addresses

  - by recipriversexclusion

  I have a server on our company intranet that runs JBoss. I want to send API calls to this server from my machine, also on the intranet, and get the resulting XML responses using JQuery. I read the entry on Wikipedia but am confused how that applies to my situation, since our machines only have IP addresses, not domain names. I have server URL: 10.2.200.3:8001/serviceroot/service client IP address: 10.2.201.217 My questions are: As far as I understand these are different domains, right? So I have to use a proxy to issue JQuery.ajax calls to the server If I want to avoid doing (2), can I install Apache on the server and server the page with JS code form there? But then the JS will be from 10.2.200.3 and the server is at 10.2.200.3:8001. Aren't these considered different domains according to policy? Thanks!

• Use HttpGet with illegal characters in the URL

  - by kaciula

  I am trying to use DefaultHttpClient and HttpGet to make a request to a web service. Unfortunately the web service URL contains illegal characters such as { (ex: domain.com/service/{username}). It's obvious that the web service naming isn't well written but I can't change it. When I do HttpGet(url), I get that I have an illegal character in the url (that is { and }). If I encode the URL before that, there is no error but the request goes to a different URL where there is nothing. The url, although has illegal characters, works from the browser but the HttpGet implementation doesn't let me use it. What should I do or use instead to avoid this problem?

• MVC in a Google App Engine Java world

  - by thatismatt

  I'm coming to Java from C# & ASP.NET MVC, I'd love to find an equivalent in the Java world that I could use on the Google App Engine. I've already started to have a play with FreeMarker and even made the first steps towards writing a very simple framework. Ideally I wouldn't have to do all the hard work though, someone must have done this already! So my question is - what frameworks are there out there that would be familiar for me coming from ASP.NET MVC and I could use them on Google App Engine for Java. The key things I'd want are: Simple Routing - /products/view/1 gets mapped to the view action of the products controller with the productid of 1 Template Engine - some way of easily passing 'ViewData' to the view, and from the view easily accessing it, ideally I'd love to avoid anything that is too XMLy (thus why I like FreeMarker).

• List of objects to JSON to Html Table?

  - by DaveDev

  If I have a list of objects IEnumerable<MyType> myTypes; Is it possible for me to return this to the client as JSON return Json(myTypes); and if so, is it possible for me to convert this (now JSON format) list to a when it gets to the client? Is there any jQuery plugin to do this? The thing is, there's loads of other stuff I need to send as JSON also, so generating a table with a PartialView and embedding that into the JSON is a extra complexity that I'd like to avoid. Thanks.

• how to stop directory structure from being viewable in J2EE apps

  - by Omnipresent

  in a J2EE app if user explicitly takes out the the ending page name then what is the best way to not show the directory structure? Example: /mycoolapp/somefolder/test.jsp /mycoolapp/somefolder/ -- this will show all the files under 'somefolder' What is the best way to redirect or show the user a page saying 'not where you belong'. I want to avoid providing index.jsp in all the folders/subfolders of my application. Appserver being used is GlassFish. Also the app is using Struts2 framework, though not all of the code is in struts2. Some code is using traditional Servlets

• Is it possible to compile Silverlight controls project with Nant?

  - by Vish

  Hi all, I am attempting to compile my Silverlight control project with Nant without luck. Since my project contains XAML files, I am not sure if Nant is capable of generating the .g.cs files from the XAML file to be compiled into the project. I have come across posts where people suggest using the MsBuild task. Is there a way to avoid using the MsBuild task and compile the project using just Nant? I am not against using the MsBuild task. But would prefer to not use it if possible. Thank You, Vish

• Memory leak in WPF app due to DelegateCommand.

  - by Abdullah BaMusa

  I just finished desktop apps written in WPF and c# using MVVM pattern. In this app I used Delegate Command implementation to wrap the ICommands properties exposed in my ModelView. The problem is these DelegateCommands prevent my ModelView and View from being garbage collected after closing the view. So it stays larking until I terminate the whole application. I profile the application I find it’s all about delegatecommand that keeping the modelview in memory. How could I avoid this situation and is this in nature of mvvm pattern, or it’s about my implantation of the pattern?. Thanks

• Merging deletes in a Team Foundation Server baseless merge

  - by Justin Dearing

  I have two TFS branches that do not have a direct parent/child relationship in TFS. In a certain revision, 94 in my example, several items were deleted. I have been tasked with applying those deletes to the main branch. I'd like to do so through a baseless merge. I tried the following command to do so: tf merge /baseless /recursive /version:94 .\programs\program1 ..\Release\programs\program1 Most of the items in the tree were marked as "merge", and some were marked as "merge edit". However, none of the items were deleted at the destination. On a whim i tried to merge over a single delete like so: tf merge /baseless /recursive /version:94 .\programs\program1\source1.cs ..\Release\programs\program1\source1.cs I got the following error message: The item [TFS_PATH] does not exist at the specified version. How do I do this? Is there a way to avoid making all those deletes myself?

• linux pthread_suspend

  - by johnnycrash

  Looks like linux doesnt implement pthread_suspend and continue, but I really need em. I have tried cond_wait, but it is too slow. The work being threaded mostly executes in 50us but occasionally executes upwards of 500ms. The problem with cond_wait is two-fold. The mutex locking is taking comparable times to the micro second executions and I don't need locking. Second, I have many worker threads and I don't really want to make N condition variables when they need to be woken up. I know exactly which thread is waiting for which work and could just pthread_continue that thread. A thread knows when there is no more work and can easily pthread_suspend itself. This would use no locking, avoid the stampede, and be faster. Problem is....no pthread_suspend or _continue. Any ideas?

• Using foreach loop.

  - by Harikrishna

  I break the code of the for loop without using break like I have for loop given below.And when i is 1 or 2 or 3 or any else but if condition is true then loop will be terminated because i will be 5 if the condition is true.And so NO need of break is needed there.Beacause I do not want to use break.I have done like this here.It works. bool myCondition=false; for(int i=0;i<5;i++) { if(myCondition) { i=5; } } But now I want to use foreach loop and in this loop when some condition is true then I want to break the foreach loop code.So what should I do here for breaking the foreach loop code without using break ? Like in the above for loop I have initialize i to 5 when condition is true.In the foreach loop anything like that to do to avoid break.

• Rails 3: What is the proper way to respond to REST-ful actions with JSON in rails?

  - by Damien Wilson

  Hello SO. I'm trying to make an API for my rails application using JSON responses to RESTful resource controllers. This is a new experience for me, so I'm looking for some guidance and pointers. To start things off: In a rails application, what is the "proper" way to respond with JSON to REST-ful controller methods? (create, update, destroy) Is there an idiomatic way to indicate success/failure through a JSON response? Additional information: I'm currently working with rails 3.0.beta2 I would like to avoid using a plugin or gem to do the grunt work, my goal is to gain a better understanding of how to make a rails 3 API. Links to places I could find more information on the topic would also be appreciated, some quick searching on google didn't do me much good.

• Best Practices for working with files via c#

  - by user177883

  Application I work on generates several hundreds of files in a 15 minutes period of times. and the back end of the application takes these files and process them (updates database with those values). One problem is database locks. What are the best practices on working with several thousands of files to avoid locking and efficiently processing these files? Would it be more efficient to create a single file and process it? or process single file at a time? What are so common best practices?

• How to access the Desktop Composition Engine from a WinForms app?

  - by MusiGenesis

  Is it possible to access Desktop Composition Engine in Windows Vista from a winforms application? The DCE apparently involves applications rendering to DCE buffers instead of directly to the screen. Since a winforms app has no way of getting information about the monitor's refresh rate and scanline status (other than via DirectX), animation in a winforms app is subject to tearing effects. With DCE enabled, the tearing effects are lessened but still there (apparently the DCE can still grab a buffer that your app is halfway through writing to and render it to the screen, thereby producing the half-one-frame-half-of-the-next tearing effects). Is there any way for my winforms app to communicate with the DCE and possible avoid rendering during buffer switchover times?

• is it possible to issue dynamic include in asp-classic?

  - by opensas

  I mean, like php'h include... something like my_file_to_be_included = "include_me.asp" -- for what I've seen so far, there are a couple of alternatives, but every one of them has some sort of shortcoming... what I'm trying to figure out is how to make a flexible template system... without having to statically include the whole thing in a single file with a loooooong case statement... here there are a couple of links a solution using FileSysmemObject, just lets you include static pages idem yet another one same thing from adobe this approach uses Server.Execute but it has some shortcomings I'd like to avoid... seems like (haven't tried yet) Server.Execute code runs in another context, so you can't use it to load a functions your are planning to use in the caller code... nasty... same thing I think this one is the same this looks promising!!! I'm not sure about it (couldn't test it yet) but it seems like this one dinamycally handles the page to a SSDI component... any idea???

• Tortoise SVN tree conflict with myself

  - by Jesse Pepper

  Has anyone had the experience of moving a file in tortoise and committing successfully, only to later commit a different change and be told of a tree conflict where: the file in its original location has been deleted, but in tortoise is marked as missing the file in its new location is there, but marked as already added. (I use tortoise SVN, and we have client and server 1.60) Nobody else changed either the directory or the file (according to svn log). Why is this happening? Is there a way to avoid it happening? If it does happen, is there a more elegant way of fixing the problem than by deleting the whole folder and updating again?

• Implement 3270 protocol in Java

  - by G B

  I've got a big problem with IBM HACL for accessing a server which speaks 3270 protocol. The library keeps crashing, and our JNI wrapper is actually a bug-fixing layer for the poorly-implemented and poorly-documented library (and I suspect we have introduced new bugs with it too). Moreover, in our company, everybody knows Java, and could maintain the software if we didn't have the JNI-Layer and the IBM class library. We have to use the C++ class library, because the IBM Java library is unusable: we get every non-printable character translated, and we lose all control characters along the way. Now the question is: can we ditch this library and implement our solution in Java completely (we'd like to avoid using another library from another vendor)? Is the protocol well documented? Is the implementation of 3270-over-ssl really so complex? Thanks.

• Accessing Bluetooth virtual COM port on Windows without manual pairing

  - by oo_olo_oo

  I need to connect to a Bluetooth device through virtual COM port created in Windows. It's easy when the port has been already created during manual pairing procedure. But I would like my application to relieve an user from the manual pairing of a device. I would like to present all devices in the range, allow user to chose one, and then create virtual COM port connected with the selected device. I'm not trying to avoid the pairing procedure itself, but rather I would like to invoke it by my application. I started getting familiar with Microsoft Bluetooth API. And then some doubts arose. I've been wondering what happen if some user would use different (than Microsoft's) Bluetooth stack? Is the Microsoft's API the real Bluetooth API, which have to be implemented by any other Bluetooth stack provider? Or rather each provider has its own API, and the Microsoft's is only one of many other?

• sqlce in Xenocode

  - by jankhana

  I'm using Xenocode in my application so that it works without a .NET framework. I'm using Xenocode Virtual Application Studio(version 6.1). Everything works fine except the .sdf file which I have embedded inside the application directory. actually in the application the instead of SQL server i have used SQL Compact edition(3.5) and i have included the reqired dll . All the files are working except the ".sdf" file. Any idea y is that so? Is it because the ".sdf" file is being used when the xenocode after snapshot was taken? if so what is the solution for that? i cannot avoid using it because Xenocode's after snapshot will not recognise the application if it's not running and if I run the application ".sdf" file will be used. Anyway to solve this?

• Most mind-blowing C++ hack you've ever seen?

  - by sblom

  In the same spirit as the "Hidden features of X?" series, what are the most mind-blowingly well-executed "I didn't even think the language could do that!" hacks that you've ever seen in C++. For example, my recent favorite is an implementation of the "operator" --> for pre-C++0x lambdas. Another fantastic example is Multi-dimensional analog literals. (Note: this is a community wiki question to avoid the appearance of reputation-whoring.)

• Security for ASP.NET application running on intranet / VPN

  - by Ryan

  Hi, I have an ASP.NET app that sits on our intranet, using the WindowsIdentity to identify the user: WindowsIdentity wi = HttpContext.Current.User.Identity as WindowsIdentity; if (wi == null || wi.Name == null) { noAccess("No WindowsIdentity"); return; } string username = wi.Name; if (username.Contains("\\")) username = username.Substring(username.LastIndexOf("\\") + 1); This works fine on our Intranet. However, when users from other offices (separate network, with firewall open) they get a password request input box. Why are they getting the password dialogue? What is the recommended way identify users of the app? I want to avoid using password, but windows identities. Anyone attempting to access the application is inside a trusted network. Thanks a lot for any help Ryan

• Drawing an NSAttributedString into a non-rectangular CGPath?

  - by Adrian Kosmaczewski

  I generate a rather complex NSAttributedString in my iOS 3.2 application (iPad), including formatting options of type CTParagraphStyleSetting, in particular with values for kCTParagraphStyleSpecifierMinimumLineHeight and kCTParagraphStyleSpecifierParagraphSpacing. When I try to draw this attributed string into a non-rectangular CGPath, Core Text draws it but without the line spacing defined; that is, all text appears crammed in paragraphs without line spacing. Needless to say, it does not look as pretty as if the CGPath was simply defined using a single call to CGPathAddRect()! Is there any setting I can specify (to my CTFramesetterRef or to the CTFrameRef associated to the culprit CGPath) to avoid losing all line height information? Thanks!
