  • Getting Public Info about Location in Facebook Graph API

    - by Allan Deamon
    I need to get the living city of each person in a group. Including people that are not my friends. In the browser seeing facebook profile of some unknown person, they show "lives in ...", if this is set as public information. They include the link to the city object with the city id in the link. That's all that I need. But, using a facebook app that I created to use the facebook graph api, this information is not public. I can only get the user propriety 'location' from friends of my that I have permission to see it. I gave ALL the possible permissions to my app. In the api explorer, when I use it as REST, they show few informations about someone not friend of mine. https://developers.facebook.com/tools/explorer/ Also in the api explorer, when I use the FQL, it didn't works. This query works, returning the JSON with the data: SELECT uid, name FROM user WHERE username='...'; But this other query doesn't work: SELECT uid, name, location FROM user WHERE username='...'; They return a json with a error code: { "error": { "message": "(#602) location is not a member of the user table.", "type": "OAuthException", "code": 602 } } I asked for ALL the permissions options in the token. And I can get this info in the browser version of the facebook. But how can I get it with the API ?

  • asp.net C# windows authentication iss config

    - by user1566209
    I'm developing a webpage where a need to know the users windows authentication values, more precisely the name. Others developments have been done with this kind of authentication but sadly for me their creators are long gone and i have no contact or documentation. I'm using Visual Studio 2008 and i'm accessing a webservice that is in a remote server. The server is a windows server 2008 r2 standard and is using ISS version 7.5. Since i have the source code of the other developments what i did was copy paste and was working fine when i was calling the webservice that was in my machine (localhost). The code is the following: //1st way WindowsPrincipal wp = new WindowsPrincipal(WindowsIdentity.GetCurrent()); string strUser = wp.Identity.Name;//ALWAYS GET NT AUTHORITY\NETWORK SERVICE //2nd way WindowsIdentity winId = WindowsIdentity.GetCurrent(); WindowsPrincipal winPrincipal = new WindowsPrincipal(winId); string user = winPrincipal.Identity.Name;//ALWAYS GET NT AUTHORITY\NETWORK SERVICE //3rd way IIdentity WinId = HttpContext.Current.User.Identity; WindowsIdentity wi = (WindowsIdentity)WinId; string userstr = wi.Name; //ALWAYS GET string empty btn_select.Text = userstr; btn_cancelar.Text = strUser; btn_gravar.Text = user; As you can see i have here 3 ways to get the same and in a sad manner show my user's name. As for my web.config i have: <authentication mode="Windows"/> <identity impersonate="true" /> In the IIS manager i have tried lots of combination of enable and disable between Anonymous Authentication, ASP.NET Impersonation, Basic Authentication, Forms Authentication and Windows Authentication. Can please someone help me?? NOTE: The respective values i get from each try are in the code

  • ASP can't connect to SQL Server database

    - by birdus
    I'm trying to get a classic ASP application to connect to a local SQL Server 2008 database. The app and database were built by someone else. I'm just trying to get them installed and running on my machine (Windows 7). I'm getting the following error when when the ASP app tries to connect to the database: Could not connect to database: Error Number: -2147467259 Error Message: [ConnectionOpen (Connect()).] does not exist or access denied. I don't see any messages in the Windows Event Viewer. I'm looking at: Event Viewer-Windows Logs-Application. It's a fresh database install using a simple restore. The SQL Server install uses the default instance. SQL Server and Windows authentication are both allowed. I left the existing connection string (in the ASP code) in tact and just tried adding that to my SQL Server installation. Here's the connection string: strConn = "PROVIDER=SQLOLEDB;SERVER=localhost;UID=TheUser;PWD=ThePassword;DATABASE=TheDatabase;" To add that user to SQL Server, I went to Security/Logins in SSMS and added the user and the password. I selected the database in question as the Default database. I thought that might do the trick, but it didn't. Then, I went into TheDatabase, then went into Security there. I added a new user there, referencing the new user I had already added in server Security. Under Owned Schemas, I clicked db_owner and under Role Members I checked db_accessadmin and db_owner. None of this gave the ASP application access to the database. The sid values match in sys.database_principals and sys.server_principals for the login in question. I am able to login to SSMS using this login. The app needs to execute selects against the database like this: oConn.Execute('select * from someTable') I'm not a DBA and am sort of grasping at straws here. How do I get this thing connected? Thanks, Jay

  • Career Choice in JEE, are EJBs standard?

    - by John Baker
    I have chosen to go the JEE route for a career path but I have been having a hard time determining which core technologies that I need to be most familiar with. I'm at the point I can write web apps without a problem with JSP's and regular servlets using JDBC or some basic Hibernate stuff (I know, HTML, CSS and have used MVC extensively on a number of different platforms). What I'm trying to find out is if there is some standard as far as J2EE technologies go. When I look at most of the Job listings, occasionally you will see someone mention Struts or Spring but rarely do I see any mention of EJB's. So my question is really, are EJB's basically required by most JEE employers? Or are most of them working with POJO's? Is it a mix? I have a hard time figuring out if I should put the majority of my time into Struts, Spring/Hibernate, EJB's, etc. And if I do need to master EJB's what version should I learn? 2.1 or 3.0. 3.0 has some obviously better features but I figure a lot of companies probably chose to write their apps in 2.1 just because it was the standard of the time and now migrating would be a big deal. Any advice on this is greatly appreciated.

  • OpenID Authentication using AuthLogic

  • Help me to refactor this F# code to tail recursion

    - by Kev
    I write some code to learning F#. Here is a example: let nextPrime list= let rec loop n= match n with | _ when (list |> List.filter (fun x -> x <= ( n |> double |> sqrt |> int)) |> List.forall (fun x -> n % x <> 0)) -> n | _ -> loop (n+1) loop (List.max list + 1) let rec findPrimes num= match num with | 1 -> [2] | n -> let temp = findPrimes <| n-1 (nextPrime temp ) :: temp //find 10 primes findPrimes 10 |> printfn "%A" I'm very happy that it just works! I'm totally beginner to recursion Recursion is a wonderful thing. I think findPrimes is not efficient. Someone help me to refactor findPrimes to tail recursion if possible? BTW, is there some more efficient way to find first n primes?

  • Decrypting a string in C# 3.5 which was encrypted with openssl in php 5.3.2

    - by panny
    Hi everyone, maybe someone can clear me up. I have been surfing on this a while now. I used openssl from console to create a root certificate for me (privatekey.pem, publickey.pem, mycert.pem, mycertprivatekey.pfx). See the end of this text on how. The problem is still to get a string encrypted on the PHP side to be decrypted on the C# side with RSACryptoServiceProvider. Any ideas? PHP side I used the publickey.pem to read it into php: $server_public_key = openssl_pkey_get_public(file_get_contents("C:\publickey.pem")); // rsa encrypt openssl_public_encrypt("123", $encrypted, $server_public_key); and the privatekey.pem to check if it works: openssl_private_decrypt($encrypted, $decrypted, openssl_get_privatekey(file_get_contents("C:\privatekey.pem"))); Coming to the conclusion, that encryption/decryption works fine on the php side with these openssl root certificate files. C# side In same manner I read the keys into a .net C# console program: X509Certificate2 myCert2 = new X509Certificate2(); RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(); try { myCert2 = new X509Certificate2(@"C:\mycertprivatekey.pfx"); rsa = (RSACryptoServiceProvider)myCert2.PrivateKey; } catch (Exception e) { } string t = Convert.ToString(rsa.Decrypt(rsa.Encrypt(test, false), false)); coming to the point, that encryption/decryption works fine on the c# side with these openssl root certificate files. key generation on unix 1) openssl req -x509 -nodes -days 3650 -newkey rsa:1024 -keyout privatekey.pem -out mycert.pem 2) openssl rsa -in privatekey.pem -pubout -out publickey.pem 3) openssl pkcs12 -export -out mycertprivatekey.pfx -in mycert.pem -inkey privatekey.pem -name "my certificate"

  • NUnit integration programmatically with spring

    - by harkon
    Hi! I have a component based architecture framework designed and I use NUnit for isolated testing - okay so far. Now I want to enable integration tests. Therefore the tests use real implementations of the existing components. Each element of the component has a life cycle (init, start and stop) and I created a NUnit component. In the start section the Console runner of the NUnit will be executed. Okay - now if I have a test fixture class in my dlls in the execution path the runner exectues them - fine! But: And this is crucial! Each to be tested implementation exists so far in the process and I want to use this instances for testing. If I use NUnit runner in the current way each instance will be created twice - and above all: I have a spring container and a implementation registry. Via this registry I can get access to all instances in the processes. But how do I give the test fixture access to the existing registry? Good: I can start the component architecture framework in the startup of the nunit runner - but this is not what I want. My guide is the apache Cactus framework (with JUnit and tomcat, JBoss etc.) Can someone help? Thanks a lot! Check: http://cone.codeplex.com

  • FF extension: saving a value in preferences and retrieving in the js file

    - by encryptor
    I am making an extension which should take a link as the user input only once. Then the entire extension keeps using that link on various functions in the JS file. When the user changes it, the value accessed by the js file also changes accordingly. I am using the following but it does not work for me var pref_manager = Components.classes["@mozilla.org/preferencesservice;1"].getService(Components.interfaces.nsIPrefService) function setInstance(){ if (pref_manager.prefHasUserValue("myvar")) { instance = pref_manager.getString("myvar"); alert(instance); } if(instance == null){ instance = prompt("Please enter webcenter host and port"); // Setting the value pref_manager.setString("myvar", instance); } } instance is the global variable in which i take the user input. The alert (instance) does not show up, which means there is some problem by the way i am saving the pref or extracting it. Can someone please help me with this. I have never worked with preferences before. so even if there are minor problems i might not be able to figure out.

  • how to check null value of Integer type field in ASP.NET MVC view?

    - by Vikas
    Hi, I have integer type field in database which is having property "Not Null". when i create a view & do a validation, if i left that field blank, it will consider it as 0 so i can not compare it with 0 because if someone insert a value 0 then it will be considered as error! one another problem is that i am using Model error as described in the book "ASP.NET MVC 1.0" @ Scott Gu blog. And I am checking the value in partial class of object (created by LINQ-To-SQL). i.e public partial class Person { public bool IsValid { get { return (GetRuleViolations().Count() == 0); } } public IEnumerable<RuleViolation> GetRuleViolations() { if (String.IsNullOrEmpty(Name)) yield return new RuleViolation("Name is Required", "Name"); if (Age == 0) yield return new RuleViolation("Age is Required", "Age"); yield break; } partial void OnValidate(ChangeAction action) { if (!IsValid) throw new ApplicationException("Rule violations prevent saving"); } } There is also problem with range. Like in database if i declared as smallint i.e. short in c#, now if i exceed that range then it gives error as "A Value is reguired". so finally is there any best way for validation in ASP.NET MVC?

  • Jquery and PHP rating function problem

    - by Sergio
    I know that I was already posted similar question but I just can't find the answer and figure it out how to solve this problem. I'm trying to customize Jquery Star Rating plugin (link text) but I do not know what to do to show the message based on response of PHP script. Jquery script successfully send rating data to PHP scripts that query the database and based on that echo message of proper or improper rating. What should I add to an existing JS code so I can get echo from PHP and base on that write a message on some DIV beside rating star? Jquery: $('#gal').rating('gl.php?gal_no=<?=$gal_no;?>&id=<?=$id;?>', {maxvalue:10,increment:.5, curvalue: <?=$cur;?>}); Simplified PHP code: $br=mysql_query("SELECT count(gal) as total FROM ...") if ... { echo '0'; } else echo '1'; } Jquery code successfully transmitted data to PHP script and when the PHP done with checking data echo the result ('1' or '0'). How can I get this PHP result back to Jquery and based on them write a message? Something like: if(data=="1") { $("#error").show("fast").html('not correct').css({'background-color':'#F5F5F5','border-color' : '#F69'}); }else{ $("#error").show("fast").html('correct').css({'background-color' : '#FFF','border-color' : '#3b5998'}); } If someone has an idea...I would appreciate it.

  • Importing data from third party datasource (open architecture design )

    - by mare
    How would you design an application (classes, interfaces in class library) in .NET when we have a fixed database design on our side and we need to support imports of data from third party data sources, which will most likely be in XML? For instance, let us say we have a Products table in our DB which has columns Id Title Description TaxLevel Price and on the other side we have for instance Products: ProductId ProdTitle Text BasicPrice Quantity. Currently I do it like this: Have the third party XML convert to classes and XSD's and then deserialize its contents into strong typed objects (what we get as a result of this process is classes like ThirdPartyProduct, ThirdPartyClassification, etc.). Then I have methods like this: InsertProduct(ThirdPartyProduct newproduct) I do not use interfaces at the moment but I would like them to. What I would like is implement something like public class Contoso_ProductSynchronization : ProductSynchronization InsertProduct(ContosoProduct p) where ProductSynchronization will be an interface or abstract class. There will most likely be many implementations of ProductSynchronization. I cannot hardcode the types - classes like ContosoProduct, NorthwindProduct might be created from the third party XML's (so preferably I would continue to use deserialization). Hopefully someone will understand what I'm trying to explain here. Just imagine you are the seller and you have numerous providers and each one uses their own proprietary XML format. I don't mind the development, which will of course be needed everytime new format appears, because it will only require 10-20 methods to be implemented, I just want the architecture to be open and support that.

  • Javascript Selectbox refresh necessary in YUI 3, when selecting none?

    - by Jasie
    Hi all, I'm using YUI 3 to let someone click "Select All" or "Select None" and then have the selectbox select all the items or unselect all of them, respectively. Here's my code: // This selects all Y.on('click',function (e) { selectBoxNode.get("options").each(function () { this.removeAttribute('selected'); this.setAttribute('selected','selected'); }); }, selectAllNode ); // This selects none Y.on('click',function (e) { selectBoxNode.get("options").each(function () { this.setAttribute('selected','false'); this.removeAttribute('selected'); }); selectBoxNode.('selectedIndex',-1); }, selectNoneNode ); selectAllLink, selectNoneLink, and selectBoxNode are self-evident, properly returned Nodes. Update: selectAll works, I had to manually remove the 'selected' attribute for each and re-add it. The selectNoneLink doesn't work: it unselects only the elements that weren't before selected... although DOM inspection shows that the selectedIndex attribute is indeed changed to -1, so maybe it needs a refresh? Any help would be appreciated. If this happens in all frameworks, that would be nice to know as well. Thanks!

  • Hierarchy of meaning

    - by asldkncvas
    I am looking for a method to build a hierarchy of words. Background: I am a "amateur" natural language processing enthusiast and right now one of the problems that I am interested in is determining the hierarchy of word semantics from a group of words. For example, if I have the set which contains a "super" representation of others, i.e. [cat, dog, monkey, animal, bird, ... ] I am interested to use any technique which would allow me to extract the word 'animal' which has the most meaningful and accurate representation of the other words inside this set. Note: they are NOT the same in meaning. cat != dog != monkey != animal BUT cat is a subset of animal and dog is a subset of animal. I know by now a lot of you will be telling me to use wordnet. Well, I will try to but I am actually interested in doing a very domain specific area which WordNet doesn't apply because: 1) Most words are not found in Wordnet 2) All the words are in another language; translation is possible but is to limited effect. another example would be: [ noise reduction, focal length, flash, functionality, .. ] so functionality includes everything in this set. I have also tried crawling wikipedia pages and applying some techniques on td-idf etc but wikipedia pages doesn't really do much either. Can someone possibly enlighten me as to what direction my research should go towards? (I could use anything)

  • How do I rewrite a for loop with a shared dependency using actors

    - by Thomas Rynne
    We have some code which needs to run faster. Its already profiled so we would like to make use of multiple threads. Usually I would setup an in memory queue, and have a number of threads taking jobs of the queue and calculating the results. For the shared data I would use a ConcurrentHashMap or similar. I don't really want to go down that route again. From what I have read using actors will result in cleaner code and if I use akka migrating to more than 1 jvm should be easier. Is that true? However, I don't know how to think in actors so I am not sure where to start. To give a better idea of the problem here is some sample code: case class Trade(price:Double, volume:Int, stock:String) { def value(priceCalculator:PriceCalculator) = (priceCalculator.priceFor(stock)-> price)*volume } class PriceCalculator { def priceFor(stock:String) = { Thread.sleep(20)//a slow operation which can be cached 50.0 } } object ValueTrades { def valueAll(trades:List[Trade], priceCalculator:PriceCalculator):List[(Trade,Double)] = { trades.map { trade => (trade,trade.value(priceCalculator)) } } def main(args:Array[String]) { val trades = List( Trade(30.5, 10, "Foo"), Trade(30.5, 20, "Foo") //usually much longer ) val priceCalculator = new PriceCalculator val values = valueAll(trades, priceCalculator) } } I'd appreciate it if someone with experience using actors could suggest how this would map on to actors.

  • Possibility of a custom Contacts field with a set list of values and Contacts lookup performance

    - by areyling
    I'm pretty sure it's not viable to do what I'd like to based on some initial research, but I figured it couldn't hurt to ask the community of experts here in case someone knows a way. I'd like to create a custom field for contacts that the user is able to edit from the main Contacts app; however, the user should only be allowed to select from a list of four specific values. A short list of string values would be ideal, but an int with a min/max range would suffice. I'm interested in knowing if it's possible either way, but also wondering if it make sense to go this route performance wise. More specifically, would it be better to look up a contact (based on a phone number) each time a call or SMS message is received or better to store my own set of data (consisting of name, numbers, and the custom field) and just syncing contact info in a thread every so often? Or syncing contacts the first time the app is run and then registering for changes using ContentObserver? Here is a similar question with an answer that explains how to add a custom field to a contact. Thanks in advance.

  • UITabBarController with viewControllers utilizing different orientations?

    - by RickiG
    Hi I can see that this is something that has been troubling a lot of people:/ I have a UITabBarController that has 4 viewControllers, all of type UINavigationController. One of the navigationControllers gets a viewController pushed onto its stack, this viewController should be presented in landscape mode/orientation. The viewController is a graph, it is the absolutely only place in the app where landscape makes sense. (I hide the UITabBar when this is presented to not lead the user to believe this will work everywhere) To make a UITabBarController respond correctly to changes in orientation all its viewControllers need to return the same value from the delegate method: - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation So to accomodate this behavior I have implemented this method in all the viewControllers belonging to the UITabBarController: - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; BOOL canRotate = [defaults boolForKey:@"can_rotate"]; return canRotate; } The "trick" is now that when my can-be-landscape viewController is pushed I do this: - (void) viewWillAppear:(BOOL)animated { NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; [defaults setBool:YES forKey:@"can_rotate"]; [defaults synchronize]; } and when it is popped, I do this: - (void) viewWillDisappear:(BOOL)animated { NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; [defaults setBool:NO forKey:@"can_rotate"]; [defaults synchronize]; } This works really well. When the viewController is on the stack I can rotate the device and the view follows. The problem is however, that if the user taps the "back" button on the navigationBar while in landscape mode, thus popping the viewController to the previous viewController, this "old" viewController is of course also in landscape mode. To make things worse, because I set the BOOL to NO, this "old" viewController can not rotate back when I orientate the device to portrait mode. Is there a way to update everything so that none of my other viewControllers will be in landscape mode when I pop the can-be-in-landscape mode viewController? I am a bit worried that if this could be done from landscape to portrait it should also be possible from portrait to landscape, thus making my "hack" unnecessary.. but if it can not, then I am back to square one :/ Hope I am close and that someone could help me get there, thanks:)

  • Every flash uploader giving bad progress values.

    - by Mike Boers
    The file upload script I wrote early last year for an internal website has been misbehaving oddly on a number of machines. On some machines it consistently works fine, on others it consistently misbehaves. I am having exactly the same problem with YUI Uploader, SWFUpload (2.2 and 2.5a), and Uploadify. On the misbehaving machines, the progress event (or callback as the case may be) is reporting the upload going far too quickly. It is progressing around 9 or 10MB/s, instead of the 50 or 60kb/s that is actually going on. The progress bar fills up very quickly, and then no more progress events are triggered. A few minutes later the completion event will trigger when the upload is actually done. I must emphasize that the file upload does proceed normally, even though the progress being reported is very wrong. The progress events are reporting a correct file size, but the reported amount uploaded is usually way too high, and it appears that it is always a multiple of 2^16 (65536). I'm only having this problem with Firefox 3.5 on Windows XP, all of which have various subversions of Flash 10. Has anyone heard of this happening, or have any idea what is going on? (I'm off to go file a number of bug reports, but hopefully someone here has some previous experience with this.)

  • Usage of Assert.Inconclusive

    - by Johannes Rudolph
    Hi, Im wondering how someone should use Assert.Inconclusive(). I'm using it if my Unit test would be about to fail for a reason other than what it is for. E.g. i have a method on a class that calculates the sum of an array of ints. On the same class there is also a method to calculate the average of the element. It is implemented by calling sum and dividing it by the length of the array. Writing a Unit test for Sum() is simple. However, when i write a test for Average() and Sum() fails, Average() is likely to fail also. The failure of Average is not explicit about the reason it failed, it failed for a reason other than what it should test for. That's why i would check if Sum() returns the correct result, otherwise i Assert.Inconclusive(). Is this to be considered good practice? What is Assert.Inconclusive intended for? Or should i rather solve the previous example by means of an Isolation Framework?

  • Module not found

    - by TMP
    Hi There! I've been working on this one quite a bit and haven't gotten any closer to a solution. I juut dug up my old copy of the WindowsHookLib again - It's available with source at http://www.codeproject.com/KB/DLL/WindowsHookLib.aspx. This library allows Global Windows Mouse/Keyboard/Clipboard Hooks, which is very useful. I'm trying to use the Mouse Hook in here to Capture Mouse-Motion (I could use a Timer that always polls Cursor.Position, but I plan on using more features of WindowsHookLib later). Code as follows: MouseHook mh = new MouseHook(); mh.InstallHook(); mh.MouseMove += new EventHandler<WindowsHookLib.MouseEventArgs>(mh_MouseMove); But on the call to InstallHook(), I get an Exception: "The specified Module could not be found". Strange. Searching, I found that someone thought this occurs because a DLL is not in a place included in the Windows PATH variable, and because placing it in system32 didn't help I went the whole hog and translated the thing to C# for inclusion directly in my project (I was curious how it works). However the error was obstinately persistent, so I dug a bit on this, and found the Code in the Library that is responsible: In InstallHook(), we have IntPtr hinstDLL = Marshal.GetHINSTANCE(Assembly.GetExecutingAssembly().GetModules()[0]); this._hMouseHook = UnsafeNativeMethods.SetWindowsHookEx(14, this._mouseProc, hinstDLL, 0); if (this._hMouseHook == IntPtr.Zero) { throw new MouseHookException(new Win32Exception(Marshal.GetLastWin32Error()).Message); } And this (after modification and recompile) tells me that what I'm really getting is a Windows error "ERROR_MOD_NOT_FOUND"! Now, Here I'm stumped. Didn't I just compile the Hook Library directly into my project? (UnsafeMethods.SetWindowsHookEx is just a DllImported Method from user32) Any Answers, or Prods in the right direction, or any hints, pointers or similar are very much appreciated!

  • Getting a Specified Cast is not valid while importing data from Excel using Linq to SQL

    - by niceoneishere
    This is my second post. After learning from my first post how fantastic is to use Linq to SQL, I wanted to try to import data from a Excel sheet into my SQL database. First My Excel Sheet: it contains 4 columns namely ItemNo ItemSize ItemPrice UnitsSold I have a created a database table with the following fields table name ProductsSold Id int not null identity --with auto increment set to true ItemNo VarChar(10) not null ItemSize VarChar(4) not null ItemPrice Decimal(18,2) not null UnitsSold int not null Now I created a dal.dbml file based on my database and I am trying to import the data from excel sheet to db table using the code below. Everything is happening on click of a button. private const string forecast_query = "SELECT ItemNo, ItemSize, ItemPrice, UnitsSold FROM [Sheet1$]"; protected void btnUpload_Click(object sender, EventArgs e) { var importer = new LinqSqlModelImporter(); if (fileUpload.HasFile) { var uploadFile = new UploadFile(fileUpload.FileName); try { fileUpload.SaveAs(uploadFile.SavePath); if(File.Exists(uploadFile.SavePath)) { importer.SourceConnectionString = uploadFile.GetOleDbConnectionString(); importer.Import(forecast_query); gvDisplay.DataBind(); pnDisplay.Visible = true; } } catch (Exception ex) { Response.Write(ex.Source.ToString()); lblInfo.Text = ex.Message; } finally { uploadFile.DeleteFileNoException(); } } } // Now here is the code for LinqSqlModelImporter public class LinqSqlModelImporter : SqlImporter { public override void Import(string query) { // importing data using oledb command and inserting into db using LINQ to SQL using (var context = new WSDALDataContext()) { using (var myConnection = new OleDbConnection(base.SourceConnectionString)) using (var myCommand = new OleDbCommand(query, myConnection)) { myConnection.Open(); var myReader = myCommand.ExecuteReader(); while (myReader.Read()) { context.ProductsSolds.InsertOnSubmit(new ProductsSold() { ItemNo = myReader.GetString(0), ItemSize = myReader.GetString(1), ItemPrice = myReader.GetDecimal(2), UnitsSold = myReader.GetInt32(3) }); } } context.SubmitChanges(); } } } can someone please tell me where am I making the error or if I am missing something, but this is driving me nuts. When I debugged I am getting this error when casting from a number the value must be a number less than infinity I really appreciate it

  • I made a horrible loop.... help fix my logic please

    - by Webnet
    I know I'm doing this a bad way... but I'm having trouble seeing any alternatives. I have an array of products that I need to select 4 of randomly. $rawUpsellList is an array of all of the possible upsells based off of the items in their cart. Each value is a product object. I know this is horribly ugly code but I don't see an alternative now.... someone please put me out of my misery so this code doesn't make it to production..... $rawUpsellList = array(); foreach ($tru->global->cart->getItemList() as $item) { $product = $item->getProduct(); $rawUpsellList = array_merge($rawUpsellList, $product->getUpsellList()); } $upsellCount = count($rawUpsellList); $showItems = 4; if ($upsellCount < $showItems) { $showItems = $upsellCount; } $maxLoop = 20; $upsellList = array(); for ($x = 0; $x <= $showItems; $x++) { $key = rand(0, $upsellCount); if (!array_key_exists($key, $upsellList) && is_object($rawUpsellList[$key])) { $upsellList[$key] = $rawUpsellList[$key]; $x++; } if ($x == $maxLoop) { break; } } Posting this code was highly embarassing...

  • Polymorphic urls with singular resources

    - by Brendon Muir
    I'm getting strange output when using the following routing setup: resources :warranty_types do resources :decisions end resource :warranty_review, :only => [] do resources :decisions end I have many warranty_types but only one warranty_review (thus the singular route declaration). The decisions are polymorphically associated with both. I have just a single decisions controller and a single _form.html.haml partial to render the form for a decision. This is the view code: = simple_form_for @decision, :url => [@decision_tree_owner, @decision.becomes(Decision)] do |form| The warranty_type url looks like this (for a new decision): /warranty_types/2/decisions whereas the warranty_review url looks like this: /admin/warranty_review/decisions.1 I think because the warranty_review id has no where to go, it's just getting appended to the end as an extension. Can someone explain what's going on here and how I might be able to fix it? I can work around it by trying to detect for a warranty_review class and substituting @decision_tree_owner with :warranty_review and this generates the correct url, but this is messy. I would have thought that the routing would be smart enough to realise that warranty_review is a singular resource and thus discard the id from the URL. This is Rails 3 by the way :)
