  • JSON request failing because of line breaks, how to escape them?

    - by mrblah
    Hi, My JSON request seems to be failing because of line breaks (I am programatically weaving my own JSON string). How can I escape for line breaks? {"rc": "200", "m" : "", "o": "<div class='s1'> <div class='avatar'> <a href='\/asdf'>asdf<\/a><br \/> <strong>0<\/strong> <\/div> <div class='sl'> <p> 444444444 <\/p> <\/div> <div class='clear'> <\/div> <\/div>"} string jsonString = BuildJSON(someCollection).Replace(@"/", @"\/");

  • Fancybox can't open partial view

    - by 1110
    I want to open partial view in fancybox like a modal view but when I click on the link it opens whole new page but it should open that in fancybox. I don't know if this is important but I have one more function that open images in fancybox (on the same page) and it works. Class names are different @Html.ActionLink("Feedback", "New", "Feedback", null, new { @class = "lightbox" }) JS $('.lightbox').fancybox(); Action method public ActionResult New() { return PartialView(); }

  • Multithreading recommendation based on program description

    - by user260197
    I would like to describe some specifics of my program and get feedback on what the best multithreading model to use would be most applicable. I've spent a lot of time now reading on ThreadPool, Threads, Producer/Consumer, etc. and have yet to come to solid conclusions. I have a list of files (all the same format) but with different contents. I have to perform work on each file. The work consists of reading the file, some processing that takes about 1-2 minutes of straight number crunching, and then writing large output files at the end. I would like the UI interface to still be responsive after I initiate the work on the specified files. Some questions: What model/mechanisms should I use? Producer/Consumer, WorkPool, etc. Should I use a BackgroundWorker in the UI for responsiveness or can I launch the threading from within the Form as long as I leave the UI thread alone to continue responding to user input? How could I take results or status of each individual work on each file and report it to the UI in a thread safe way to give user feedback as the work progresses (there can be close to 1000 files to process) Update: Great feedback so far, very helpful. I'm adding some more details that are asked below: Output is to multiple independent files. One set of output files per "work item" that then themselves gets read and processed by another process before the "work item" is complete The work items/threads do not share any resources. The work items are processed in part using a unmanaged static library that makes use of boost libraries.

  • Populating FullCalendar events from MVC

    - by jasonmhirst
    I've having difficulty in populating FullCalendar from MVC and would like a little assistance on the matter please. I have the following code for my controller: Function GetEvents(ByVal [start] As Double, ByVal [end] As Double) As JsonResult Dim sqlConnection As New SqlClient.SqlConnection sqlConnection.ConnectionString = My.Settings.sqlConnection Dim sqlCommand As New SqlClient.SqlCommand sqlCommand.CommandText = "SELECT tripID AS ID, tripName AS Title, DATEDIFF(s, '1970-01-01 00:00:00', dateStart) AS [Start], DATEDIFF(s, '1970-01-01 00:00:00', dateEnd) AS [End] FROM tblTrip WHERE userID=18 AND DateStart IS NOT NULL" sqlCommand.Connection = sqlConnection Dim ds As New DataSet Dim da As New SqlClient.SqlDataAdapter(sqlCommand) da.Fill(ds, "Meetings") sqlConnection.Close() Dim meetings = From c In ds.Tables("Meetings") Select {c.Item("ID"), c.Item("Title"), "False", c.Item("Start"), c.Item("End")} Return Json(meetings.ToArray(), JsonRequestBehavior.AllowGet) End Function This does indeed run correctly but the format that is returned is: [[25,"South America 2008","False",1203033600,1227657600],[48,"Levant 2009","False",1231804800,1233619200],[49,"South America 2009","False",1235433600,1237420800],[50,"Italy 2009","False",1241049600,1256083200],[189,"Levant 2010a","False",1265414400,1267574400],[195,"Levant 2010a","False",1262736000,1262736000],[208,"Levant 2010a","False",1264982400,1267574400],[209,"Levant 2010a","False",1264982400,1265587200],[210,"Levant 2010","False",1264982400,1266969600],[211,"Levant 2010 b","False",1267056000,1267574400],[213,"South America 2010a","False",1268438400,1269648000],[214,"Levant 2010 c","False",1266364800,1264118400],[215,"South America 2010a","False",1268611200,1269648000],[217,"South America 2010","False",1268611200,1269561600],[218,"South America 2010 b","False",1268956800,1269388800],[227,"levant 2010 b","False",1265846400,1266192000]] And this is totally different to what I've seen on the post from here: http://stackoverflow.com/questions/2445359/jquery-fullcalendar-json-date-issue (note the lack of tag information and curly braces) Can someone please explain to me what I may be doing wrong and why my output isn't correctly formatted.

  • Cannot debug views in MVC2 project, getting "The resource cannot be found" error

    - by schefdev
    I'm running Visual Studio 2008 sp1 on Win7, with MVC2 RTM installed. I created a new MVC2 project using the wizard and am unable to debug specific pages. With webforms and even MVC1, I was able to sit on a View page, hit F5, and then have the integrated web server in VS2008 start on the page I was working on. Very handy for building up app logic. When I try this now I get a "The resource cannot be found" error page. I retried this just now with a stock new MVC2 Web Application project. Here are the steps I took after creating the new project to reproduce: Open up project settings. Under the Web subtab, set the Start Action to "Current Page". Leave all the other settings as is. Open one of the views up (e.g. Account/Register.aspx) Hit F5 to debug the project Note that the browser window which displays shows the error message "The resource cannot be found". The link I saw in my browser for this run was: http://localhost:49471/Views/Account/Register.aspx I did some googling and found suggestions related to ensuring all HTTP server pieces were installed. I double checked and made sure that "HTTP Errors" and "HTTP Redirection" were both installed. If I leave the project setting as it was originally, set to "Specific Page" with nothing in the text box, then routing works and I always get the default home page. I'm hoping this isn't the only option. Thanks!

  • Attempting to update partial view using Ajax.ActionLink gives error in MicrosoftAjax.js

    - by mwright
    I am trying to update the partial view ( "OnlyPartialView" ) from an Ajax.ActionLink which is in the same partial view. While executing the foreach loop it throws this error in a popup box in visual studio: htmlfile: Unknown runtime error This error puts the break point in the MicrosoftAjax.js file, Line 5, Col 83,632, Ch 83632. The page is not updated appropriately. Any thoughts or ideas on how I could troubleshoot this?

  • What is the advantage of WSDualHttpBinding in WCF?

    - by schmoopy
    How much benefit would there be to using WSDualHttpBinding with IIS hosted service vs. a client poll that calls the WCF service, assuming in the latter the service cached the data in question? This scenerio would be for a notify type of service where the clients need to be notified by the service when an event occurs. Specifically, what advantages would WSDualHttpBinding provide over polling? ie: Less network traffic, faster to design, easier to maintain, more control ??? From what i understand, WSDualHttpBinding is less scalable than client polling, so why use it at all? Edit: As Matt supplied, time critical can be one reason for the duplex binding. Here is what i have so far: WSDualHttpBinding adv: can get immediate response w/o waiting on polling timer dis: less scalable than WsHttpBinding dis: less firewall friendly I'll add to this based on comments, please let me know if i state anything incorrectly. thanks for you input :-)

  • Explicit construction of entity type [MyClass] in query is not allowed.

    - by Code Sherpa
    Hi. Like the title says, I have the following exception: Description: Event code: 3005 Event message: An unhandled exception has occurred. Exception information: Exception type: NotSupportedException Exception message: Explicit construction of entity type 'Company.Project.Core.Domain.Friend' in query is not allowed. I am using LINQ and have the following code in my datacontext: var friends2 = (dc.Friends .Where(f => f.MyFriendsAccountId == accountId && f.AccountId != accountId) .Select(f => new { f.FriendId, AccountId = f.MyFriendsAccountId, MyFriendsAccountId = f.AccountId, f.CreateDate, f.Timestamp })).Distinct(); result.AddRange(friends2 .Select(o => new Friend { FriendId = o.FriendId, AccountId = o.AccountId, CreateDate = o.CreateDate, MyFriendsAccountId = o.MyFriendsAccountId, Timestamp = o.Timestamp })); the final code block is throwing the error and I am pretty sure it is this statement that is the culprit: .Select( o => **new Friend** How should I be reworking my code to avoid this error? Code illustration appreciated. Thanks.

  • DateTimePicker automatically move to next datepart

    - by Leon Tayson
    Currently, when using the datetimepicker, after you enter the month you have to either hit the right arrow or the "/" for it to move to the day. Is there a property that I can set or a way to know that the month is done and move to the day and move to the year after the user is done with the day? This is the same behavior with applications written in the old FoxPro/Clipper days.

  • LINQ to SQL SOUNDEX - possible?

    - by Steve Hayes
    Hello, I have done a little bit of research on this and looked through a few articles both here on StackOverflow as well as some blog posts, but haven't found an exact answer. I also read that it is possible to do it using the 4.0 framework, but have yet to find any supporting evidence. So my question, is it possible to perform SOUNDEX via a LINQ to SQL Query?

  • Convert IEnumerable to EntitySet

    - by Gregorius
    Hey all, Hoping somebody can shed some light, and perhaps a possible solution to this issue I'm having... I have used LINQ to SQL to pull some data from a database into local entities. They are products from a shopping cart system. A product can contain a collection of KitGroups (which are stored in an EntitySet (System.Data.Linq.EntitySet). KitGroups contain collections of KitItems, and KitItems can contain Nested Products (which link back up to the original Product type - so its recursive). From these entities I'm building XML using LINQ to XML - all good here - my XML looks beautiful, calling a "GenerateProductElement" function, which calls itself recursively to generate the nested products. Wonderful stuff. However, here's where i'm stuck.. i'm now trying to deserialize that XML back to the original objects (all autogenerated by Linq to SQL)... and herein lies the problem. Linq tO Sql expects my collections to be EntitySet collections, however Linq to Xml (which i'm tyring to use to deserailise) is returning IEnumerable. I've experimented with a few ways of casting between the 2, but nothing seems to work... I'm starting to think that I should just deserialise manually (with some funky loops and conditionals to determine which KitGroup KitItems belong to, etc)... however its really quite tricky and that code is likely to be quite ugly, so I'd love to find a more elegant solution to this problem. Any suggestions? Here's a code snippet: private Product GenerateProductFromXML(XDocument inDoc) { var prod = from p in inDoc.Descendants("Product") select new Product { ProductID = (int)p.Attribute("ID"), ProductGUID = (Guid)p.Attribute("GUID"), Name = (string)p.Element("Name"), Summary = (string)p.Element("Summary"), Description = (string)p.Element("Description"), SEName = (string)p.Element("SEName"), SETitle = (string)p.Element("SETitle"), XmlPackage = (string)p.Element("XmlPackage"), IsAKit = (byte)(int)p.Element("IsAKit"), ExtensionData = (string)p.Element("ExtensionData"), }; //TODO: UUGGGGGGG Converting b/w IEnumerable & EntitySet var kitGroups = (from kg in inDoc.Descendants("KitGroups").Elements("KitGroup") select new KitGroup { KitGroupID = (int) kg.Attribute("ID"), KitGroupGUID = (Guid) kg.Attribute("GUID"), Name = (string) kg.Element("Name"), KitItems = // THIS IS WHERE IT FAILS - "Cannot convert source type IEnumerable to target type EntitySet..." (from ki in kg.Descendants("KitItems").Elements("KitItem") select new KitItem { KitItemID = (int) ki.Attribute("ID"), KitItemGUID = (Guid) ki.Attribute("GUID") }); }); Product ImportedProduct = prod.First(); ImportedProduct.KitGroups = new EntitySet<KitGroup>(); ImportedProduct.KitGroups.AddRange(kitGroups); return ImportedProduct; }

  • NullReferenceException when calling InsertOnSubmit in Linq to Sql.

    - by Charlie
    I'm trying to insert a new object into my database using LINQ to SQL but get a NullReferenceException when I call InsertOnSubmit() in the code snippet below. I'm passing in a derived class called FileUploadAudit, and all properties on the object are set. public void Save(Audit audit) { try { using (ULNDataClassesDataContext dataContext = this.Connection.GetContext()) { if (audit.AuditID > 0) { throw new RepositoryException(RepositoryExceptionCode.EntityAlreadyExists, string.Format("An audit entry with ID {0} already exists and cannot be updated.", audit.AuditID)); } dataContext.Audits.InsertOnSubmit(audit); dataContext.SubmitChanges(); } } catch (Exception ex) { if (ObjectFactory.GetInstance<IExceptionHandler>().HandleException(ex)) { throw; } } } Here's the stack trace: at System.Data.Linq.Table`1.InsertOnSubmit(TEntity entity) at XXXX.XXXX.Repository.AuditRepository.Save(Audit audit) C:\XXXX\AuditRepository.cs:line 25" I've added to the Audit class like this: public partial class Audit { public Audit(string message, ULNComponent component) : this() { this.Message = message; this.DateTimeRecorded = DateTime.Now; this.SetComponent(component); this.ServerName = Environment.MachineName; } public bool IsError { get; set; } public void SetComponent(ULNComponent component) { this.Component = Enum.GetName(typeof(ULNComponent), component); } } And the derived FileUploadAudit looks like this: public class FileUploadAudit : Audit { public FileUploadAudit(string message, ULNComponent component, Guid fileGuid, string originalFilename, string physicalFilename, HttpPostedFileBase postedFile) : base(message, component) { this.FileGuid = fileGuid; this.OriginalFilename = originalFilename; this.PhysicalFileName = physicalFilename; this.PostedFile = postedFile; this.ValidationErrors = new List<string>(); } public Guid FileGuid { get; set; } public string OriginalFilename { get; set; } public string PhysicalFileName { get; set; } public HttpPostedFileBase PostedFile { get; set; } public IList<string> ValidationErrors { get; set; } } Any ideas what the problem is? The closest question I could find to mine is here but my partial Audit class is calling the parameterless constructor in the generated code, and I still get the problem. UPDATE: This problem only occurs when I pass in the derived FileUploadAudit class, the Audit class works fine. The Audit class is generated as a linq to sql class and there are no Properties mapped to database fields in the derived class.

  • SQLiteDataAdapter Fill exception

    - by Lirik
    I'm trying to use the OleDb CSV parser to load some data from a CSV file and insert it into a SQLite database, but I get an exception with the OleDbAdapter.Fill method and it's frustrating: An unhandled exception of type 'System.Data.ConstraintException' occurred in System.Data.dll Additional information: Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints. Here is the source code: public void InsertData(String csvFileName, String tableName) { String dir = Path.GetDirectoryName(csvFileName); String name = Path.GetFileName(csvFileName); using (OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + dir + @";Extended Properties=""Text;HDR=No;FMT=Delimited""")) { conn.Open(); using (OleDbDataAdapter adapter = new OleDbDataAdapter("SELECT * FROM " + name, conn)) { QuoteDataSet ds = new QuoteDataSet(); adapter.Fill(ds, tableName); // <-- Exception here InsertData(ds, tableName); // <-- Inserts the data into the my SQLite db } } } class Program { static void Main(string[] args) { SQLiteDatabase target = new SQLiteDatabase(); string csvFileName = "D:\\Innovations\\Finch\\dev\\DataFeed\\YahooTagsInfo.csv"; string tableName = "Tags"; target.InsertData(csvFileName, tableName); Console.ReadKey(); } } The "YahooTagsInfo.csv" file looks like this: tagId,tagName,description,colName,dataType,realTime 1,s,Symbol,symbol,VARCHAR,FALSE 2,c8,After Hours Change,afterhours,DOUBLE,TRUE 3,g3,Annualized Gain,annualizedGain,DOUBLE,FALSE 4,a,Ask,ask,DOUBLE,FALSE 5,a5,Ask Size,askSize,DOUBLE,FALSE 6,a2,Average Daily Volume,avgDailyVolume,DOUBLE,FALSE 7,b,Bid,bid,DOUBLE,FALSE 8,b6,Bid Size,bidSize,DOUBLE,FALSE 9,b4,Book Value,bookValue,DOUBLE,FALSE I've tried the following: Removing the first line in the CSV file so it doesn't confuse it for real data. Changing the TRUE/FALSE realTime flag to 1/0. I've tried 1 and 2 together (i.e. removed the first line and changed the flag). None of these things helped... One constraint is that the tagId is supposed to be unique. Here is what the table look like in design view: Can anybody help me figure out what is the problem here? Update: I changed the HDR property from HDR=No to HDR=Yes and now it doesn't give me an exception: OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + dir + @";Extended Properties=""Text;HDR=Yes;FMT=Delimited"""); I assumed that if HDR=No and I removed the header (i.e. first line), then it should work... strangely it didn't work. In any case, now I'm no longer getting the exception. The new problem is here: public void InsertData(QuoteDataSet data, String tableName) { using (SQLiteConnection conn = new SQLiteConnection(_connectionString)) { conn.Open(); using (SQLiteDataAdapter sqliteAdapter = new SQLiteDataAdapter("SELECT * FROM " + tableName, conn)) { Console.WriteLine("Num rows updated is " + sqliteAdapter.Update(data, tableName)); } } } Now the Num rows updated is 0... any hints?

  • Display cross domain content in IFrame (IE8)

X-FRAME-OPTIONS : "DENY" (This does not display any IFrame content ) X-FRAME-OPTIONS : "SAMEORIGIN" (Displays content from the same domain) Is there a work around to allow content from other domains to be displayed? Thanks in advance

  • Should I buy Obout? Help, Please.

    - by Ramiz Uddin
    We started a new project and the nature of the project is very interactive and a Rich UI is required. We would need a set of controls that would require for Rich UI development. I found Obout while googling. I never heard about them and never seen fellow members telling me such name except Telerik, ComponentOne, NetAdvantage. These are the famous names we heard but no this one. But, the controls give a positive feeling. But as two things matter always when you are buying some services: How good are their customer support? and How much feasible their price is? Another, How quickly they release patches/updates? As, what if we find a bug or an error during development what will gonna happen? Do they provide a quick solution for this? I hope you understand my query. I'm bit confused making a decision here. I need your assistance, experience and feedback. Please, assist! Thanks.

  • Impersonation - Access is denied

    - by krisg
    I am having trouble using impersonation to delete a PerformanceCounterCategory from an MVC website. I have a static class and when the application starts it checks whether or not a PerformanceCounterCategory exists, and if it contains the correct counters. If not, it deletes the category and creates it again with the required counters.

  • AJAX TabContainer containing user controls

    - by Ali
    Hi all, Wondering if someone here can help. I have an AJAX tabcontainer which has a number of tabs and each tab contains a user control. When I add a new item from one of the tabs, it is not reflected in the user control in another tab unless a postback occurs. (e.g. the first tab has a listview where I add a new record and the second has a simple form which contains a drop-down which I expect to contain value added from first tab). How can I make the tabcontainer to refresh its tabs from a usercontrol? Any help will be most appreciated. Thanks, Ali
