• WPF: Binding items added to UserControl's exposed children

  - by Brian

  I have a user control that allows items to be added to it by exposing a Grid's Children property. Any control I add shows up fine but when I try to bind a property on the added item to a control in the main window nothing happens (example): <TextBox Name="txtTest" Text="Success!" /> <mycontrols:CustomUserControl.ExposedGridChildren> <TextBox Text="{Binding ElementName=txtTest, Path=Text, FallbackValue=fail}"/> </mycontrols:CustomUserControl.ExposedGridChildren> This example always results in the TextBox's text showing "fail". Here is how I'm exposing the children in the user control: public UIElementCollection ExposedGridChildren { get { return grdContainer.Children; } } Any thoughts? Is it a scope issue? I know I can't name the elements I add to the children because of scope errors. Thanks, Brian.

• How to Store Cookies in Ruby?

  - by viatropos

  I am programmatcally accessing authenticated content in my CDN on Google App Engine, and it's returning a cookie that I'm supposed to store: {"set-cookie"=>"ACSID=cookie-hash; expires=Mon, 12-Apr-2010 01:56:06 GMT; path=/"} What do I do with that? This is my first time dealing with Cookies. I can put in the header of the next request, but what's the recommended way to store that? I'm testing this with irb in the console and when I exit and try again, the cookie is gone. How do I save it for a few days/weeks? I'm using pure ruby without Rails or anything. Thanks so much.

• List available languages for PyGTK UI strings

  - by detly

  I'm cleaning up some localisation and translation settings in our PyGTK application. The app is only intended to be used under GNU/Linux systems. One of the features we want is for users to select the language used for the applications (some prefer their native language, some prefer English for consistency, some like French because it sounds romantic, etc). For this to work, I need to actually show a combo box with the various languages available. How can I get this list? In fact, I need a list of pairs of the language code ("en", "ru", etc) and the language name in the native language ("English (US)", "???????"). If I had to implement a brute force method, I'd do something like: look in the system locale dir (eg. "/usr/share/locale") for all language code dirs (eg. "en/") containing the relative path "LC_MESSAGES/OurAppName.mo". Is there a more programmatic way?

• git-diff in another directory

  - by ABach

  I'm currently writing a little zsh function that checks all of my git repositories to see if they're dirty or not and then prints out the ones that need a commit. Thus far, I've figured out that the quickest way to figure out a git repository's clean/dirty status is via git-diff and git-ls-files: if ! git diff --quiet || git ls-files --others --exclude-standard; then state=":dirty" fi I have two questions for you folks: Does anyone know of a quicker, more efficient way to check for file changes/additions in a git repo? I want my zsh function to be handed a file path (say ~/Code/git-repos/) and check all of the repositories in it. Is there a way to do without having to cd into each directory and run those commands? Something like git-diff --quiet --git-dir="~/Code/git-repos/..." would be fantastic. Thanks! :)

• .NET 2d library for circuit diagrams

  - by Dinah

  I want to draw and manipulate logic flow (as opposed to analog) circuit diagrams and I'm trying not to reinvent the wheel. Problems like positioning, line drawing, line crossing and connecting, path finding, rubberband lines, and drag & drop are also identical in flow charts, UML diagrams, or class diagrams so I started by viewing related topics via Google and Stack Overflow. However, the following requirements seemed to keep me from finding anything that quite fit: assuming a chip has an image with input and output stubs, the connecting lines would connect to the chip only in the exact spots of the I/O stubs the color of connecting lines are able to be set as per a chip's output Is there an existing .NET 2d graphics library that would be suitable for drawing circuit diagrams?

• Redis version on Cloudbees is out of date?

  - by Alan Krueger

  I'm setting up an OSS build in Cloudbees with /usr/sbin/redis-server being started as one of the build tasks: + /usr/sbin/redis-server [204] 04 Nov 03:52:58 # Warning: no config file specified, using the default config. In order to specify a config file use 'redis-server /path/to/redis.conf' [204] 04 Nov 03:52:58 * Server started, Redis version 2.0.3 The (Redis site)[http://redis.io/download] shows 2.6.2 to be the current version and 2.4.17 as "legacy". On the extended downloads page, version 2.0.3 is deprecated. Am I launching it the wrong server executable, or are there plans to support a more recent version of Redis?

• Easy way to parse a url in C++ cross platform?

  - by Andrew Bucknell

  I need to parse a url to get the protocol host path and query in an application I am writing in c++. The application is intended to be cross platform. Im surprised I cant find anything that does this in boost or poco libraries. Is it somewhere obvious Im not looking? Any suggestions on appropriate open source libs? Or is this something I just have to do my self? Its not super complicated but it seems such a common task I am surprised there isnt a common solution.

• IIS Virtual Directory/Application & Forms authentication

  - by user216194

  I've setup and deployed a simple forms authentication website with membership using .NET 4. I've created a virtual directory (now converted to "Application") in IIS7 and setup the web.config file in the virtual directory as follows: <system.webServer> <directoryBrowse enabled="true" /> </system.webServer> Great! I browse to the virtual directory: ../mydomain/books/ and I'm automatically redirected to the login page specified by web.config in my root directory and the url path is placed as follows: ../Account/Login.aspx?ReturnUrl=%2fbooks At this point, I login succesfully, but I am not redirected anywhere, and when I manually return to the directory, ../books, I'm sent back to the login page, where I'm already logged in? So I'm confused about what my problem is! I should be successfully authenticated, and than redirected back to the directory, or at the very least be able to view it manually after I log in right?

• $_GET loading content before head tag instead of in specified div.

  - by s32ialx

  NOT EDITING BELOW BUT THANKS TO SOME REALLY NICE PEOPLE I CAN'T POST AN IMAGE ANYMORE BECAUSE I HAD a 15 Rep but NOW ONLY A 5 becuase my question wasn't what they wanted help with they gave me a neg rep. The problem is that the content loads it displays UNDER the div i placed #CONTENT# inside so the styles are being ignored and it's posting #CONTENT# outside the divs at positions 0,0 any suggestions? Found out whats happening by using "View Source" seems that it's putting all of the #CONTENT#, content that's being loaded in front of the <head> tag. Like this <doctype...> <div class="home"> \ blah blah #CONTENT# bot being loaded in correct specified area </div> / <head> <script src=""></script> </head> <body> <div class="header"></div> <div class="contents"> #CONTENT# < where content SHOULD load </div> <div class="footer"></div> </body> so anyone got a fix?

• Where to open sessions in a Spring/Hibernate stack?

  - by CaptainAwesomePants

  I'm trying to figure out a good design for a Spring/Hibernate app. When creating such an app, it appears like there are a handful of major decisions. The first major decision seems to be where to put the session/transaction boundary. It seems like I have 3 major choices: as a filter before controllers are even invoked, immediately below the controllers at the service call level, and stuffed way below the business level in repository calls. It seems to me like the right call is the middle path, but I'm not sure. I don't want my transactions open too long, but at the same time, I don't want to constantly worry about detached objects and lazy loading in the business logic. Still, there are some downsides. For instance, it makes it hard for the business logic to make a remote call without holding up a transaction for a few seconds. I wonder if there's a better way?

  - by ragupathi

  I have been using rails for developing web applications and now i need to do design an api for iphone application and since i used respond to json it also produces json but i use devise for authentication in my web application and when i send email and password along with the api it gives out {"user":{"authentication_token":"Lsusyd27ewgasga63","email":"[email protected]"}} and there is forgot password functionality in the iphone app but in the web application when clicking on forgot password button it sends an email to the users email, whereby the user has to go to his mail and click on the link sent and it will take to the change password path and after changing it the user will be login but in this iphone app i want to send the password to the user mail and the user can use that password and login. How can i do this? Also do i have to create new controllers for api or the web application controller is enough if it respond as json? please help me.

• A* pathfinder obstacle collision problem

  - by Cheesebaron

  I am working on a project with a robot that has to find its way to an object and avoid some obstacles when going to that object it has to pick up. The problem lies in that the robot and the object the robot needs to pick up are both one pixel wide in the pathfinder. In reality they are a lot bigger. Often the A* pathfinder chooses to place the route along the edges of the obstacles, sometimes making it collide with them, which we do not wish to have to do. I have tried to add some more non-walkable fields to the obstacles, but it does not always work out very well. It still collides with the obstacles, also adding too many points where it is not allowed to walk, results in that there is no path it can run on. Do you have any suggestions on what to do about this problem?

• Handling duplicate nodes in XML

  - by JYelton

  Scenario: I am parsing values from an XML file using C# and have the following method: private static string GetXMLNodeValue(XmlNode basenode, string strNodePath) { if (basenode.SelectSingleNode(strNodePath) != null) return (basenode.SelectSingleNode(strNodePath).InnerText); else return String.Empty; } To get a particular value from the XML file, I generally pass the root node and a path like "parentnode/item" I recently ran into an issue where two nodes at the same document level share the same name. Question: What is the best way to get the values for duplicate-named nodes distinctly? My thought was to load all values matching the node name into an array and then using the array index to refer to them. I'm not sure how to implement that, though. (I'm not well-versed in XML navigation.)

• [PHP.ini] Can't load mcrypt.dll dynamic library.

  - by Kel

  Hey guys, I'm trying to load this module: php_mcrypt.dll' Everything in the php.ini file is correct, see for yourself: extension_dir = "C:/PHP/5.2.13/ext" extension=php_mcrypt.dll The file exists in this path. And other modules are in there as well and are loaded successfully. It only has a problem with this particular module. I have a 64bit Windows XP, Apache 2.2, PHP 5.2.13... But i get this warning (error.log of Apache): PHP Warning: PHP Startup: Unable to load dynamic library 'C:/PHP/5.2.13/ext\php_mcrypt1.dll' - The specified module could not be found.\r\n in Unknown on line 0 PHP itself is working fine. But one of our applications needs this module and it throws me this ugly error. Why on earth does it show me two backslashes in the log file?

• Web App fails when moved to production environment. Which server permissions do I need?

  - by Ashley Ward

  I have developed a small web app. This app allows users to upload images. It also produces text files with the names of those images (the names are stored and retrieved to/from an MySQL Database.) I have developed this app using MAMP. To create the uploaded image files I use the PHP function imagejpeg('my/path/name.jpg') and to delete the files I use the PHP function unlink('folder1/folder2/name.jpg') to write to the text document I am using the function fopen('folder1/folder2/name.txt', 'w') all three of these functions produce errors related to permissions - now the site has been moved to a live hosting environment. Why is this? and what permissions do I need to set the folder's folder1 and folder2 to? I know that permission 777 is generally bad because it opens up your server to the public. However what I have found is that the functions fail to work unless I use 777 on the folders. Can anyone shed any light on my dilemma?

• C#: proprietary DLLs requiring access to my assemblies

  - by Craig Johnston

  My solution uses a proprietary assembly, which when debugging the solution throws an Exception saying it can't find an assembly that is meant to be one of the projects in my solution. I cannot add a reference to the proprietary assembly because all I have is the DLL. When I compile everything into a single application directory and run the app it works fine, but I want to debug. Where should assemblies be placed if you want a proprietary assembly in the solution to see them? I assume the issue is that there is no path specified and it is just looking in a default directory of some kind.

• wanting to move up from ms access, thinking .net? visual studio?

  - by Tristan Lear

  So I wrote a project-management program for a small business using Microsoft Access 2007. Now they've requested lots of additional features (timekeeping, privileged data tiers ...) I personally use Linux, but the whole office uses Windows. I'm relatively new to programming but like to teach myself using projects like this. I'm right on the edge on this -- I can't really tell what the path of least resistance here is: do I stay in access + VBA and teach myself a dying, annoying language -- while struggling against all the limitations of Access? Or do I move to something else? Python seems simple enough ... Whatever I use, i need to be able to offer a GUI.

• Escaping CURL @ symbol with PHP

  - by bkildow

  I'm writing a php application that submits via curl data to sign up for an iContact email list. However I keep getting an invalid email address error. I think this may be due to the fact that I'm escaping the @ symbol so it looks like %40 instead of @. Also, according to the php documentation for curl_setopt with CURLOPT_POSTFIELDS: The full data to post in a HTTP "POST" operation. To post a file, prepend a filename with @ and use the full path. So, is there anyway to pass the @ symbol as post data through curl in php without running it through urlencode first?

• FileContentResult and international characters

  - by suzi167

  Hello, I am using a fileContentResult to render a file to the browser. It works well except that it throws an exception when the fileName contains international characters. I remember reading somewhere that this feature does not support international characters but I am sure there mustbe a workaround or a best practice people follow in cases the application needs to upload files in countries other than US. Does anyone know of such a practice?Here is the ActionResult Method public ActionResult GetFile(byte[] value, string fileName) { string fileExtension = Path.GetExtension(fileName); string contentType = GetContentType(fileExtension); //gets the content Type return File(value, contentType, fileName); } THanks in advance Susan

• Reference non-GAC version of DLL in Visual Studio 2010

  - by Eric J.

  This is similar to Add Non-GAC reference to project but the solutions presented there don't seem to help. I have a WinForms UI Library (Krypton from ComponentFactory) installed in the GAC. There's a bug I want to track down in that library, so I added the source code to my solution, removed the old references from my WinForms project to Krypton DLLs, added them back as a project references, ensured Copy Local is set to true, double-checked that the path (on reference properties tab) points to my local project, and... ...the GAC version is still being used while debugging. I cannot set a breakpoint in the Krypton source, Debugger.Break() or other code changes to not execute, and when I start the Visual Studio 2010 debugger, I see a Loading from ... GAC_MISL message relating to the Krypton DLLs flash by in the VS 2010 status bar. The DLLs are not copied to the WinForm's Debug folder. How can I reference the "project" version of the files while debugging while leaving them registered in the GAC?

• Stream post URL security and wall post links

  - by Jeff Lee

  Our app's mobile client can create wall post links to our app's web-facing pages. Since this happens in the context of a mobile app, we do this on behalf of our user using the Graph API's feed/message endpoint. I noticed that the links showing up in the wall posts are being routed through our app's auth dialog, which is NOT what we want. We just want transparent links, without forcing the client to auth our app, similar to what happens when you share to FB in Path. I went ahead and disabled the "Stream post URL option" several hours ago, but we still seem to be getting the re-routed links for wall posts. The target URLs for these links are within the domain we've registered for our Facebook app. Is there anything else I need to do fix this?
