  • Running Long Process: Indexing 5GB docs with Lucene

    - by Robert Dondo
    Situation:I have an ASP .NET application that will search through docs using Lucene. I want to run the initial indexing (the index will be incremental after the initial run so there wont be need to index the whole directory again in future). Currently, I have about 5GB of docs (45000files). Problem: My application times out before completing the process. I have altered the TimeOut like this: HttpContext.Current.Server.ScriptTimeout = 200000; but it still does not complete the process. How can I run the index?

  • Exception if there is IBOutlet in view controller created by initWithNibName

    - by Kail
    When I create a Navigation-based application, the second view controller is created with initWithNibName, if I add a label onto the second view and connect it with IBOutlet in the second view controller. After I navigate to the second view by clicking table cell, and then back to the root view, the application aborts - send message retainCount to a freed object. I know this is caused by the IBOutlet label, which is retained, set nil in viewDidUnload and dealloc in dealloc. But I don't know why, and if I wanna still use IBOutlet, what can I do? Not dealloc it in viewcontroller's dealloc? Anybody could help? Thank you.

  • Trouble setting FIrst view controller which will appear on App Startup

    - by Matte.Car
    I'm setting setting FIrst view controller which will appear on my App Startup. It should appear an UIView first time as a tutorial and, from second time, another standard view. In AppDelegate I wrote this: #import "AppDelegate.h" #import "TabBarController.h" #import "TutorialController.h" @implementation AppDelegate TabBarController * viewControllerStandard; // standard view TutorialController * viewControllerFirst; // tutorial view @synthesize window; - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { if ([@"1" isEqualToString:[[NSUserDefaults standardUserDefaults] objectForKey:@"Startup"]]) { window.rootViewController = viewControllerStandard; } else { window.rootViewController = viewControllerFirst; } [window makeKeyAndVisible]; return YES; } It doesn't return any alert but, launching app, after splashscreen, it appear only a black screen. Without that codes everything works fine. What could be wrong? Thank you!

  • How to authenticate users against a Windows AD?

    - by Potinos
    I've a JSF-Hibernate web application. I need to authenticate users against a Windows AD and the web application should only allow logins from members of group X, otherwise it should redirect to an error page. How can I configure this? Also, I would like to display the name of the logged-in user on all pages, not the name of the Windows user of the server machine. I have tried the System.property("user.name") for this, but this only returns the name of the Windows user of the server name.

  • Why do I get "could not load type" error with my custom SessionStateProvider

    - by Rising Star
    My associate has created a custom SessionStateProvider for me to use with my ASP.net application. I add the file CustomSessionStateProvider to my VS2008 Web Application Project and put the appropriate reference in the web.config and it works fine. However, my supervisor wants me to set this up as a GAC reference. At my office, we have many DLLs we've created that we use as GAC references across different projects. If I add my CustomSessionStateProvider to the Global Assembly Cache, my pages throw a could not load type CustomASP.CustomSessionStateProvider error. Simple removing the DLL from the GAC makes it work again, but I want to set this up as a GAC reference. What could be causing this problem?

  • Get newly created window using Win32 API hooks

    - by Nathan W
    This may be a long short or not even possible but no harm in asking. What I am trying to do is monitor an application for any new windows it creates in its MDI control. I have implemented hooking in C# and can capture the MDICREATE window message but because I need to get information about the window after is has been created the MDICREATE message isn't much help because at that stage the window hasn't been created in the other application yet. Without going into to much detail I just need to be able to see when a new window has been created. Is this possible? Thanks

  • AcceptSecurityContext (Kerberos) returns SEC_E_LOGON_DENIED

    - by Davatuk
    Hi, I am trying to write a simple application that performs Kerberos authentication (no mutual authentication for now). The operating system is Windows server 2003, standard edition. I have setup Active directory and created an SPN using setspn tool. AcquireCredentialsHandle returns SEC_E_OK both on client and on server. InitializeSecurityContext on client side returns SEC_E_OK. AcceptSecurityContext on server side returns SEC_E_LOGON_DENIED. I am sure there's nothing wrong in my code since the same behaviour I see when using the sample application from the following MSDN article: http://msdn.microsoft.com/en-us/magazine/dvdarchive/bb985043.aspx So I guess there is something wrong in my setup. But I can't find out what. Maybe I have missed something in SPN setup? Any help is appreciated. Regards, David.

  • In a process using lots of memory, how can I spawn a shell without a memory-hungry fork()?

    - by kdt
    On an embedded platform (with no swap partition), I have an application whose main process occupies most of the available physical memory. The problem is that I want to launch an external shell script from my application, but using fork() requires that there be enough memory for 2x my original process before the child process (which will ultimately execl itself to something much smaller) can be created. So is there any way to invoke a shell script from a C program without incurring the memory overhead of a fork()? I've considered workarounds such as having a secondary smaller process which is responsible for creating shells, or having a "watcher" script which I signal by touching a file or somesuch, but I'd much rather have something simpler.

  • WCF net.tcp server disconnects - how to handle properly on client side?

    - by RoastedBattleSquirrel
    I'm stuck with a bit of an annoying problem right now. I've got a Silverlight 4 application (which runs OOB by default). It uses WCF with net.tcp as means of communicating with the server. The client uses a central instance of the wcf client proxy. As long as everything keeps running on the server side, everything's fine. If i kill the server in the middle of everything, i drown in an avalanche of exceptions on the client side (connection lost, channel faulted etc etc). Now i'm looking for a way to handle this in a clean and centralized way (if centralized is possible). The SL app has one central client object sitting in App.cs (public static MyClient Client { get;set;}), which gets initialized on application start. Any idea how to properly handle any connectivity problems on the client object?

  • sqlite3 date operations when joining two tables in a view?

    - by duncan
    In short, how to add minutes to a datetime from an integer located in another table, in one select statement, by joining them? I have a table P(int id, ..., int minutes) and a table S(int id, int p_id, datetime start) I want to generate a view that gives me PS(S.id, P.id, S.start + P.minutes) by joining S.p_id=P.id The problem is, if I was generating the query from the application, I can do stuff like: select datetime('2010-04-21 14:00', '+20 minutes'); 2010-04-21 14:20:00 By creating the string '+20 minutes' in the application and then passing it to sqlite. However I can't find a way to create this string in the select itself: select p.*,datetime(s.start_at, formatstring('+%s minutes', p.minutes)) from p,s where s.p_id=p.id; Because sqlite as far the documentation tells, does not provide any string format function, nor can I see any alternative way of expressing the date modifiers.

  • How to create Ribbon tabs dynamically?

    - by Lari13
    I want to start developmet of new application using PrismV4, MEF, Ribbon. But now, I have a problem. How to create tabs for Ribbon dynamically? Each module in application could create own tab in Ribbon. And each tab may have many groups. How can it be done? Where do I need to place each group's definitions (what controls to use (buttons, textboxes, comboboxes, etc) and command bindings and how? Do I need to write XAML somewhere in Module, or all it can be done by code? And last question, how to notify Ribbon (in Shell) to add these tabs to Ribbon? Shall I use EventAggregator to communicate from Module to Shell? Or? Thanks for any advices and Happy New Year :)

  • free RSS feed caching

    - by cherouvim
    Hello I've got an application which serves an rss feed of headlines and I need to provide this rss feed to other consumers. I don't want to provide the rss directly from my server though, due to limited server resources, so I need to proxy (cache) it through some service which will handle the load. Assuming the rss feed URL of my application is http://example.com/rss I initially provided my consumers with the url http://ajax.googleapis.com/ajax/services/feed/load?v=1.0&q=http%3A%2F%2Fexample.com%2Frss which solved my server load problem but introduced a liveness problem. The headlines are minutes to hours late from the actual feed (haven't exactly measured how much late). I've also tried distributing through feedburner so the url became something like http://feeds.feedburner.com/example123?format=xml but the liveness problem still exists. Is there a public and free solution for this problem? Anything below 5 minutes of liveness delay would be totally acceptable. thanks

  • Parse raw HTTP Headers

  • How do I create a point system in a Rails app that assigns points to users and non-authenticated-use

    - by codyvbrown
    I'm building a question and answer application on top of twitter and I'm hitting some snags because I'm inevitably dealing with two classes of users: authenticated and non-authenticated. The site enable users to give points to other users, who may or may not be authenticated, and I want to create a site-wide point system where the application stores and displays this information on their profile. I want to save this point data to the user because that would be faster and more efficient but non-authenticated users aren't in our system, we only have the twitter handle. So instead we display the points in our system like this: @points = point.all( :select => "tag, count(*) AS count", # Return tag and count :group => 'tag', # Group by the tag :order => "2 desc", :conditions => {:twitter_handle => params[:username]}) Is there a better way to do this? Is there a better way to associate data with non-authenticated users?

  • how to integrate Zend Framework MVC with existing site

    - by Joel
    Hi guys, So I'm slowly tackling OO and Zend Framework and their MVC process in particular. I have an existing website and web-based calendar application that was designed by me, but coded by a different person and done procedurally. I understand that it will be very difficult for my application to ever be completely OO without a full re-write, and I'm fine with that. I have a lot of updates and modifications I want to do in the future, so I'm wanting to start replacing some of the basic components (login, authentication. etc) now, and continue to learn as I go. Again, I'm really a newbie at programming and OO. What I'm wondering is if I'm wanting to incorporate the Framework, then would I just first drop my whole site into the /public folder of the Framework and then start pulling functionality out from there?

  • How to duplicate INSERTS into a seperate table?

    - by Ash
    An iPhone application I have installed uses an SQLite database to log entries with basic INSERTS and DELETES being performed on it. However I wish to keep a permanent log of the INSERTS made to this table, so when an INSERT occurs, I want it to be written to another table also as to create a log. I don't have access to the application source code in order to modify the SQL statements made, I do have access to the SQLite database. Can I do this with triggers? If so can somebody provide a short example.
