• How practical to change MVC app from traditional authentication to cookieless?

  - by Phil.Wheeler

  I have an application written in MVC that uses your regular .Net Forms Authentication. There's nothing particularly new or exciting going on with it. My client has now asked that users be able to log in to the app on the same machine but in different browsers, or different tabs within the same browser. To my mind, he's asking for a scope change to have authentication moved to cookieless instead of its current design. Not having had any experience with doing this in MVC, I'm curious to know before I get started how much hurt I'm in for by trying this. Are there better ways to do it? What should I consider? Any advice appreciated.

• What are these lines doing?

  - by Montecristo

  I'm starting learning javascript for a project, I've found a script that does a part of what I need to do, I'd like to know how it works, both for me and in case it needs to be modified. Originally it was used inside the page, now I've put it in a file on its own and does not work anymore, so I'm dividing it in parts, because I fail to get the whole thing. Here is what bother me most for now: 1) Is this a declaration a function? What is its name? How can it be invoked? (function() { //some code })(); 2) No clue of what is going on here var VARIABLE = VARIABLE || {}; 3) Am I defining a the implementation of methodCall here? Something like overriding a method in Java? VARIABLE.methodCall = function(parameter) { console.log("parameter was: " + parameter); }; Thank you in advance for your help.

• Git: Merge in only one commit

  - by Ivan

  Usually, I work with branches in Git, but I don't like to see hundreds of branches in my working tree (Git history). I'm wondering if there is a method in Git to "join" all commits in a branch in only one commit (ideally with a clear commit message). Something like this: git checkout -b branch <some work> git commit -a -m "commit 1" <some work> git commit -a -m "commit 2" <some work> git commit -a -m "commit 3" git checkout master git SUPER-JOIN branch -m "super commit" After this, only "super commit" will exist in the git log.

• Monitoring .NET ASP.NET Applications

  - by James Hollingworth

  I have a number of applications running on top of ASP.NET I want to monitor. The main things I care about are: Exceptions: We currently some custom code which will email us when an exception occurs. If the application is failing hard it will crash our outlook... I know (and use) elmah which partly solves the problem however it is still just a big table of exceptions with a pretty(ish) UI. I want something that makes sense of all of these exceptions (e.g. groups exceptions, alerts when new ones occur, tells me what the common ones are that I should fix, etc) Logging: We currently log to files which are then accessible via a shared folder which dev's grep & tail. Does anyone know of better ways of presenting this information. In an ideal world I want to associate it with exceptions. Performance: Request times, memory usage, cpu, etc. whatever stats I can get I'm guessing this is probably going to be solved by a number of tools, has anyone got any suggestions?

• Python - react to custom keyboard interrupt

  - by flixic

  Hello. I am writing python chatbot that displays output through console. Every half second it asks server for updates, and responds to message. In the console I can see chat log. This is sufficient in most cases, however, sometimes I want to interrupt normal workflow and write custom chat answer myself. I would love to be able to press a button (or combination) that would switch to "custom reply mode". What is the best way to do that, or achieve similar result? Thanks a lot!

• What is possible causes of Jasper Exception

  - by CitadelCSCadet

  I have a JSP that takes an Arraylist from the session object and removes the items from it. It seemed to be working fine and then out of nowhere when I navigate to that page, the page is blank. I checked the tomcat log files and in catalina.out I am receiving a Jasper Exception an it is showing it as being on a line with the following for(int i; i < agentItems.size(); i++) agentItems is the name of the ArrayList I am using. I have been debugging it and cant seem to figure out what the problem might be. I have read that a JasperException is sometiems thrown as a JSP's NullPointerException. Is this true or am I just completely overlooking the problem? I have the web application running on a local machine and a intermediate server for development in which both of them have had no trouble. Why could it be that only on this server it is giving me problems?

• Visual Studio 2008 Create Word 2007 Template Project Crashes

  - by Rob

  I've got this weird crashing happening when creating a C# Word 2007 Template Project in Visual Studio 2008. The IDE tells me that it's creating the project (it does create the solution and C# vsproj as well as the dotx and cs files). Then the IDE just crashes - no errors, messages, etc. When I try devenv /SafeMode it still doesn't work. I've also tried devenv /log but I don't really see any smoking guns. I have VS2008 SP1 and VSTO 3.0 SP1 installed. Anybody know why this is occurring or more importantly, how I can get it to stop?

• Displaying and capturing c# exceptions

  - by Frank Meulenaar

  I have a c# program which throws a NullReferenceException(). When I start this on my Vista machine, it gives the familiar screen "Foo has stopped working". I can easily click on 'details' to see what went wrong. On one XP machine there's no warning at all: the program just quits, and on another XP I get the "Foo has encountered a problem..." message. Is there a way I can change this (XP's) setting? Furthermore, I would like to have this error message written to a log file, so I can see what went wrong if somebody else uses my program. Is there a way I can send the uncaught exceptions to a file?

• Win32 Thread Exits Unexpectedly

  - by sahs

  Hello, I'm writing a C++ application. I realized that one of my worker threads may terminate unexpectedly. The (VS 2005) debug log says: The thread 'Win32 Thread' (0x5d98) has exited with code -858993460 (0xcccccccc). I surrounded all the worker thread code with a try/catch block. So, if the reason was an exception, I would catch it. But I can't: try{ ... Connection* conn = connectionPool->getConnection(); // unexpected exit occurs here ... } catch(exception& e) { ... } I have ten threads running concurrently, and only one of them gets crashed after some time, while the others continue running (and getting new [OCCI] connections). Is there an exception type that is not caught by "exception"? Or what do I not know about threads/exceptions? Thanks.

• Having to keep on restarting the Application Pool?

  - by smclintock

  One of our major websites (built on PHP, MSSQL, IIS7) has started to become unresponsive every few hours and I'm having to log on to the server and restart the application pool. The rest of the websites on the server are fine, so I figure it may be due to a code problem? Whilst I look over all the code, specifically the database connections, would anyone have any advice on how I could better track this down to what is actually causing it to become unresponsive? By "unresponsive" I mean when you enter the URL it doesn't resolve and times out. Thanks for any help, Steven.

• .Net LoginControls - User can't logout in Firefox

  - by Jordan Foreman

  Basically, the logout link doesn't do anything, but only in Firefox. (I can login and out freely from other browsers) There really isn't a whole lot of information I can really give other than that, since I'm still new to this project and .net as a whole, and know almost nothing about the login controls. So if someone else has experienced a similar issue in the past, and can recognize the issue with the little info I have, that would be great! If not, sorry for the lack of depth, but its all I have. If it helps, here is the code for where the logout link is: <LoggedInTemplate> ... <asp:LoginStatus ID="HeadLoginStatus" runat="server" LogoutAction="Redirect" LogoutText="Log Out" LogoutPageUrl="~/Anonymous/Login.aspx" /> </LoggedInTemplate>

• Show friendly message on ASP.NET Ajax error

  - by balexandre

  You all know how annoying is this: I do have a log system and the correct error is well explicit there, but I want to give a better message to the user. I keep trying several ways but I'm using Telerik components and well jQuery and I ended up using both ASP.NET Ajax methods and jQuery, so I use function pageLoad() { try { var manager = Sys.WebForms.PageRequestManager.getInstance(); manager.add_endRequest(endRequest); manager.add_beginRequest(OnBeginRequest); manager } catch (err) { alert(err); } } as well $(document).ready(function() { ... } that alert(err) is never fired even upon OnClick events what's the best approach to avoid this message errors and provide a cleaner way? all this happens in <asp:UpdatePanel> as I use that when I didn't know better (3 years ago!) and I really don't want to mess up and build all again from scratch :( Any help is greatly appreciated Updated with more error windows after volpav solution

• Windows Platform Installer fails during Orchard Installation

  - by nullnvoid

  I'm attempting to install Orchard 1.0 on a Windows 7 box. It has only just been released. I downloaded and installed the Windows Platform Installer and attempted to install Orchard. The error message is just that the application has stopped working and asks if I want to debug or close the application. The event log contains a single error: "The event logging service encountered an error while processing an incoming event published from Microsoft-Windows-Security-Auditing." I tried installing MVC3 and it worked without issue. Has anyone experienced a similar problem?

• MD5 hash validation failing for unknown reason in PHP

  - by Sennheiser

  I'm writing a login form, and it converts the given password to an MD5 hash with md5($password), then matches it to an already-hashed record in my database. I know for sure that the database record is correct in this case. However, it doesn't log me in and claims the password is incorrect. Here's my code: $password = mysql_real_escape_string($_POST["password"]); ...more code... $passwordQuery = mysql_fetch_row(mysql_query(("SELECT password FROM users WHERE email = '$userEmail'"))); ...some code... elseif(md5($password) != $passwordQuery) { $_SESSION["noPass"] = "That password is incorrect."; } ...more code after... I tried pulling just the value of md5($password) and that matched up when I visually compared it. However, I can't get the comparison to work in PHP. Perhaps it is because the MySQL record is stored as text, and the MD5 is something else?

• Sharing some info with all DLLs pulled into a process

  - by JBRWilkinson

  Hi all, We've got an Enterprise system which has many processes (EXEs, services, DCOM servers, COM+ apps, ISAPI, MMC snapins) all of which make use of many COM components. We've recently seen failures in some of the customer deployments, but are finding it hard to troubleshoot the cause. In order to track down the problem, we've augmented the entire source with logging statements where errors occur. In order to identify which logs came from what processes, the C++ logging code (compiled into all components) uses the EXE name to name the log. This is good for some cases, but not all - COM+ apps, ISAPI and MMC snapins all have system EXE names and the logs end up interleaved. I saw this post about shared data sections which might help, but what I don't understand is who decides what goes in the shared section. Is there any way I can guarantee that a particular piece of code writes into the shared section before anyone else reads it? Or is there a better solution to this problem?

• Windows 7 UAC elevation

  - by Goz

  I have a single thread that I'd like to run as an administrator in my application. The rest of the application I can happily run as the default user level (asInvoker). Is this possible? I notice there is an "ImpersonateLoggedOnUser" function. Can I somehow use this to log the administrator on and then get the thread to impersonate that person? It seems as though this ought to be something pretty trivial to do ... but there doesn't appear to be any obvious way to do it. Can anyone help me out?

• Conflict resolution merge commit seems incomplete

  - by kayaker243

  There was a feature branch with conflicts. These were resolved and the resolution committed. Unfortunately, I botched the merge and a couple previously-released features regressed - this is verified by doing a diff between the merge commit sha1 and that of the previous tag. When I do git show <sha1 for merge commit> all changes are innocuous. When I do git log -Sunique_variable_added_for_feature_and_lost_after_botched_merge, I only see the commit that added unique_variable_... but not the problematic deletion from the bad merge. However, when I took the ignominious step of viewing the sha1 for the commit in a gui git client like Tower, I can clearly see the botched lines. Is there an additional switch used by Tower that I've missed entirely? Why didn't pickaxe pick up the deletion implicit in the merge commit?

• Facebook login on headless browser

  - by dmni

  My Facebook app has a function of automating tasks on server side headless browser (like visiting app links). Now, I use the Facebook SDKs to log user in and access user's news stream to search for links and other information. Once the app has found all the links, it is supposed to pass this information in to the headless browser which will then proceed to visit in them for example. The problem is that these headless browser windows' are not logged in. I would like the headless browser to be temporary logged in as the user launching the tasks from the app. Is this possible?

• Code is exectuting but the view is not loading when called form a function?

  - by wolverine

  I have a viewBased application with the viewController class mainView. In it I am loading various views(different nibs) depending upon certain actions that I do. I have added a popoverController with a barbutton in the mainView. Its intialized with a tableviewController class named popClass. When I select certain row in the popover, I want the view in my mainView to load someother view(as I do when i do certain actions). For that I have written a function in mainView Controller class and is calling it from the popOver class. Function and the lines of code are executing but nothing is happening. Even the log lines are printed but no action takes place. What is the problem? OR is there anyother way to make the view change in mainView by using the popover?

• Exception Handling in MVP Passive View

  - by ilmatte

  Hello, I'm wondering what's the preferred way to manage exceptions in an MVP implemented with a Passive View. There's a discussion in my company about putting try/catch blocks in the presenter or only in the view. In my opinion the logical top level caller is the presenter (even if the actual one is the view). Moreover I can test the presenter and not the view. This is the reason why I prefer to define a method in the view interface: IView.ShowError(error) and invoke it from the catch blocks in the presenter: try { } catch (Exception exception) { ...log exception... view.ShowError("An error occurred") } In this way the developers of future views can safely forget to implement exception handling but the IView interface force them to implement a ShowError method. The drawback is that if I want to feel completely safe I need to add redundant try/catch blocks in the view. The other way would be to add try catch blocks only in the views and not introducing the showerror method in the view interface. What do you suggest?

• email tracking image duplicate requests

  - by DEH

  I am embedding tracking images within emails that are being sent from a custom-built opt-in CRM system. The image src is an encoded .gif, such as src="12_34_675.gif". The image is served by an ASP.NET httphandler that decodes the src encoding and serves a transparent image. Everything works fine, but some email clients request the image multiple times, creating duplicate entries. Some clients make three calls all within one second, and some seem to make tens of calls over a day or so. Mostly email clients make single calls, but these few duplicates are very perplexing. I know I can code around them, but I'd really like to understand what's going on. I've checked the IIS log files, which show that the duplicate requests are coming from the client machines. I can't think what might be causing these duplicate http requests. Help!

• How do I retain a requested url with parameters after redirecting to a login page?

  - by Brent Parker

  I have been asked to set up some authentication for some content on our website using JSP. What I would like to do seems simple to me but I can't quite figure out how to do it in JSP. What I would like to do is this: When a user requests a page that you must be logged in to see, I have a tag that checks their cookies for an authentication token. If it is not there, they are redirected to a login page. After they log in, I want to redirect them back to the page they first requested along with any parameters they were sending. Now, I have the tag that is checking their authentication and redirecting them to the login page. That part is working just fine. But I'm not sure how to maintain the first requested url and parameters so they can be redirected after they login. How might I accomplish this?
