  • ASP.Net application timeout

    - by ClarkeyBoy
    Hi, I have an application I have just deployed which, for complicated reasons, stores all the data from the database in a module the first time any data from the specific table is required (i.e. when a customer requests to view a product for the first time, all the product data is stored in the ProductManager class (of which an instance is stored in a shared property of the SiteContent class, making the ProductManager easily accessible from any page). Now forget that you are probably now glaring at me for using this approach.. I am sure it has its inefficiencies but I have only been studying .Net for a year or so now so I am still learning. One thing I have noticed is that I can go on the site once, then revisit it 5 minutes later and it will load all the data into the ProductManager class again. It seems this is a .Net application timeout thing - since the session timeout is set to 30 minutes and, when I am logged in on the administration frontend, it logs me out after 5 minutes (ish). Does anyone have any idea how to change this? Is there any way I can change this in the code without having to contact the hosting company? If not in the code is there any way to change this in the web.config? Thanks in advance. Regards, Richard

  • Image Wells, Core Data, and Sqlite files.

    - by Sway
    I've got a mac application that I've developed. I use it to create sqlite files that are bundled with my iphone app. The mac app uses Core Data and bindings and is working fine except for one "weird" issue. I use an NSImageView (or Image Well) to allow me to drag and drop jpg files. This is bound through to an optional binary attribute in my model class. For some reason when I drag and drop a 4k jpg file it onto the image well and save the sqlite file. The data saved to the binary column is over 15 times larger than it should be. Whereas if I use an application like SQLiteManager and add the image into the row in the database. The binary data is the correct (expected size). File 4k jpg Actual size: 2371. Persisted via Core Data size: 35810. Can anyone give me a suggestion as to why this might be happening? Do I need to set some setting in Interface Builder or write some custom code?

  • Looking for advice on importing large dataset in sqlite and Cocoa/Objective-C

    - by jluckyiv
    I have a fairly large hierarchical dataset I'm importing. The total size of the database after import is about 270MB in sqlite. My current method works, but I know I'm hogging memory as I do it. For instance, if I run with Zombies, my system freezes up (although it will execute just fine if I don't use that Instrument). I was hoping for some algorithm advice. I have three hierarchical tables comprising about 400,000 records. The highest level has about 30 records, the next has about 20,000, the last has the balance. Right now, I'm using nested for loops to import. I know I'm creating an unreasonably large object graph, but I'm also looking to serialize to JSON or XML because I want to break up the records into downloadable chunks for the end user to import a la carte. I have the code written to do the serialization, but I'm wondering if I can serialize the object graph if I only have pieces in memory. Here's pseudocode showing the basic process for sqlite import. I left out the unnecessary detail. [database open]; [database beginTransaction]; NSArray *firstLevels = [[FirstLevel fetchFromURL:url retain]; for (FirstLevel *firstLevel in firstLevels) { [firstLevel save]; int id1 = [firstLevel primaryKey]; NSArray *secondLevels = [[SecondLevel fetchFromURL:url] retain]; for (SecondLevel *secondLevel in secondLevels) { [secondLevel saveWithForeignKey:id1]; int id2 = [secondLevel primaryKey]; NSArray *thirdLevels = [[ThirdLevel fetchFromURL:url] retain]; for (ThirdLevel *thirdLevel in thirdLevels) { [thirdLevel saveWithForeignKey:id2]; } [database commit]; [database beginTransaction]; [thirdLevels release]; } [secondLevels release]; } [database commit]; [database release]; [firstLevels release];

  • ASP MVC.Net 3 RC2 bug ?

    - by Jarek Waliszko
    Hello, so far I've been using ASP.Net 3 BETA. Everything was working fine till the update to RC2 version. Of course I've read ScottGu's article about RC2. My problem is following. Basically I have 2 controllers: public class DynamicPageController : Controller { public ActionResult Redirect(string resource, int? pageNumber, int? id) { } } public class SystemController : Controller { public ActionResult Index() { } } In the Globals.asax I have routes like this: public static void RegisterRoutes(RouteCollection routes) { routes.MapRoute( "SystemRoute", "System/{action}", new { controller = "System", action = "Index" } ); routes.MapRoute( "PageRoute", "{resource}/{id}/{pageNumber}", new { controller = "DynamicPage", action = "Redirect", resource = UrlParameter.Optional, pageNumber = UrlParameter.Optional, id = UrlParameter.Optional } ); } In the code, I have simple link creation: System.Web.Mvc.UrlHelper u = new System.Web.Mvc.UrlHelper(context); string url = u.Action("Index", "System"); and the url is "/my_app/System" in both versions (BETA and RC2) But the code below (the syntax is the same as above, only controller and action names are different): string url = u.Action("Redirect", "DynamicPage", new RouteValueDictionary(new { resource = "Home" })); gives url which is null in RC2. It should be (and in fact in BETA was) "/my_app/Home" Why ? Is it a bug ? How can I create url for my "DynamicPage" controller ? Regards BTW: From where can I now download ASP.Mvc BETA version along with ASP.Net Web Pages 1.0 installers ? Since RC2 announcement I have problems finding mentioned 2 installers. Normally I would upgrade my code but this issue described above makes me stay with BETA for a while, since I have no time for migration and testing everything now.

  • Problems when I try to see databases in SQLite

  • How to deploy ClickOnce .Net 3.5 application on 3.0 machine

    - by Buthrakaur
    I have .Net 3.5 SP1 WPF application which I'm successfully deploying to client computers using ClickOnce. Now I got new requirement - one of our clients need to run the application on machines equipped just with .Net 3.0 and it's entirely impossible to upgrade or install anything on the machines. I already tried to run the 3.5 application with some of the 3.5FW DLLs copied to the application directory and it worked without any problems. The only problem at the moment is ClickOnce. I already made it to include the 3.5FW System.*.dll files in list of application files, but it always aborts installation on 3.0 machine with this error message: Unable to install or run the application. The application requires that assembly System.Core Version 3.5.0.0 be installed in the Global Assembly Cache (GAC) first. Please contact your system administrator. I already tried to tweak prerequisites on Publish tab of my project, but no combination solved the issue. What part of ClickOnce is responsible for checking prerequisites? I already tried to deploy using mageui.exe, but the 3.5FW error is still present. What should I do to fore ClickOnce to stop checking any prerequisites at all? The project is created using VS2010.

  • Asp.net membership salt?

    - by chobo2
    Hi Does anyone know how Asp.net membership generates their salt key and then how they encode it(ie is it salt + password or password + salt)? I am using sha1 with my membership but I would like to recreate the same salts so the built in membership stuff could hash the stuff the same way as my stuff can. Thanks Edit 2 Never Mind I mis read it and was thinking it said bytes not bit. So I was passing in 128 bytes not 128bits. Edit I been trying to make it so this is what I have public string EncodePassword(string password, string salt) { byte[] bytes = Encoding.Unicode.GetBytes(password); byte[] src = Encoding.Unicode.GetBytes(salt); byte[] dst = new byte[src.Length + bytes.Length]; Buffer.BlockCopy(src, 0, dst, 0, src.Length); Buffer.BlockCopy(bytes, 0, dst, src.Length, bytes.Length); HashAlgorithm algorithm = HashAlgorithm.Create("SHA1"); byte[] inArray = algorithm.ComputeHash(dst); return Convert.ToBase64String(inArray); } private byte[] createSalt(byte[] saltSize) { byte[] saltBytes = saltSize; RNGCryptoServiceProvider rng = new RNGCryptoServiceProvider(); rng.GetNonZeroBytes(saltBytes); return saltBytes; } So I have not tried to see if the asp.net membership will recognize this yet the hashed password looks close. I just don't know how to convert it to base64 for the salt. I did this byte[] storeSalt = createSalt(new byte[128]); string salt = Encoding.Unicode.GetString(storeSalt); string base64Salt = Convert.ToBase64String(storeSalt); int test = base64Salt.Length; Test length is 172 what is well over the 128bits so what am I doing wrong? This is what their salt looks like vkNj4EvbEPbk1HHW+K8y/A== This is what my salt looks like E9oEtqo0livLke9+csUkf2AOLzFsOvhkB/NocSQm33aySyNOphplx9yH2bgsHoEeR/aw/pMe4SkeDvNVfnemoB4PDNRUB9drFhzXOW5jypF9NQmBZaJDvJ+uK3mPXsWkEcxANn9mdRzYCEYCaVhgAZ5oQRnnT721mbFKpfc4kpI=

  • SQLite transaction doesn't work as expected

    - by troll
    I prepared 2 files, "1.php" and "2.php". "1.php" is like this. <?php $dbh = new PDO('sqlite:test1'); $dbh->beginTransaction(); print "aaa<br>"; sleep(55); $dbh->commit(); print "bbb"; ?> and "2.php" is like this. <?php $dbh = new PDO('sqlite:test1'); $dbh->beginTransaction(); print "ccc<br>"; $dbh->commit(); print "ddd"; ?> and I excute "1.php". It starts a transaction and waits 55 seconds. So when I immediately excute "2.php", my expectation is this: "1.php" is getting transaction and "1" holds a database lock "2" can not begin a transaction "2" can not get database lock so "2" have to wait 55 seconds BUT, but the test went another way. When I excute "2",then "2" immediately returned it's result "2" did not wait so I have to think that "1" could not get transaction, or could not get database lock. Can anyone help?

  • SQLite Databases and Grid Hosting

    - by jocull
    I'm considering moving my site from a GoDaddy shared hosting account to a Media Temple grid hosting account in anticipation of traffic. However, I first have some concerns with the grid hosting setup. My site stores a large personal set of data on a per-user basis (possibly 3-4MB per user). At this rate I was worried about blowing over a 1GB MySQL limit in no time. To deal with this I created distributed SQLite databases per user to store large data objects. It's worked wonderfully so far. SQLite is super fast and simple. I know that reading from and writing to files is different in a Grid Hosting environment. I need to know if this setup is going to cause serious problems. These databases are not (and will not be) highly trafficked. They are personal to the user and will only be touched maybe two locations at the same time (one updating the data hourly at the most, and one or more reading on demand). I'd like to keep this setup as getting additional space (beyond 4GB) on a MySQL database seems to be a real trouble point. Will Grid Hosting cause me serious problems? Thanks.

  • Chinese records of sqlite databse are in not accessable in iphone app

    - by Mas
    Hi! I'm creating an iphone app. In which I'm reading data from the sqlite db and presenting it in the tableview control. Problem is that the data is in chinese language. Due to unknown reason, when I read/fetch record from the sqlite table, some records are presented and other are missed by objc. Even objc reads some columns of the missing values, But returns the nil results of the some columns. In reality these columns are not empty. I tried many solutions but didn't find any suitable. Same database is working perfectly in the android version of the app. Any one can help here is the code of reading the chinese records from table Quote *q = [[Quote alloc] init]; q.catId = sqlite3_column_int(statement, 0); q.subCatId = sqlite3_column_int(statement, 1); q.quote = [NSString stringWithUTF8String:(char *)sqlite3_column_text(statement, 2)]; and here is the some records which iphone misses ??????·??? ??????,????????! ??????,???????

  • How to write custom SQLite functions in Javascript inside a Webkit browser?

    - by Jay Godse
    I have just learned how to use the SQLite database for local storage in a Webkit web browser (e.g. Google Chrome or Apple Safari) using the Javascript API. For example the "Sticky Notes" application. However, I know that SQLite has a function called sqlite_create_function() that lets you add custom functions to your instance of SQLite on the fly which can then be used inside SQL queries. This function is described at sqlite.org. I also know that you can call an equivalent of this API in Ruby as described here. QUESTION: Can anybody show me how to do this in Javascript - i.e. write a custom function in Javascript that can be bound into the SQLite database at run time to be called by the SQLite engine, and all inside a Webkit browser?

  • Why are some seasoned ASP.NET developers defecting to Ruby on Rails?

    - by Tony_Henrich
    Once a while I hear some known ASP.NET developer declaring that they quit developing in .NET and moving to Ruby using Ruby in Rails. The problem is they don't mention exactly the reasons. They use words like RoR is 'easier', 'better' & 'faster'. That really doesn't say much to me. Anyone care to do faithful comparison using code samples, case studies ..etc or from personal experience in using both? Try to convince me to throw away all my years of learning C#, the .NET Framework using a powerful IDE (Visual Studio). Does RoR save you hours a week in development time? What are the major pain points in .NET that compels one to move away from it? This question is NOT about a pure RoR vs ASP.NET (MVC) comparison. It's about the compelling technical reasons (getting bored does not count!) to switch over after using a platform for several years and start with a new language and platform. (prefer this to be a wiki)

    Hi All, I'm not sure if it is possible to render an asp.net control from a string. The string contains fragments of html code and I've tried rendering that string to a div tag with runat="server" set, asp panel contain, asp lalbel control and asp literal control. All of them doesn't render the asp control in that text to an actual control, it just come up as a string. I've tried adding <% % around them and it appears it doesn't like it. Thanks in advance.
