• jqGrid "Loading..." overlay showing "undefined" though grid is working

  - by gurun8

  I have a jqGrid that's working 100% except that it keeps displaying "undefined" in the "Loading..." overlay. I can't really figure it out. It seems like I should only get the "undefined" message if something isn't set right and the grid would cease to work. But that's not the case. scratches head I'm not really sure a code sample would help here, but if anyone would like to see a certain part of my code let me know and I'll included. Has anyone else come across this issue before? I'm probably missing something so simple and small that I can't see it. So my apologies in advance if this is a no-brainer Thanks for your help.

• Adding custom options in binded dropdown in asp.net

  - by MarceloRamires

  I have a bound dropdown list populated with a table of names through a select, and databinding. it shoots selectedindexchanged that (through a postback) updates a certain gridview. What happens is, since it runs from changing the index, the one that always comes selected (alexander) can only me chosen if you choose another one, then choose alexander. poor alexander. What I want is to put a blanc option at the beginning (default) and (if possible) a option as second. I can't add this option manually, since the binding wipes whatever was in the dropdown list and puts the content of the datasource.

• NSUserDefaults in monotouch

  - by Ali Shafai

  I'm very impressed with MonoTouch.Dialog by Miguel. inspired by his simple approach I thought it would be very nice to have a reflection based NSUserDefaults class that works seamlessly by marking certain properties as "persistable in user defaults" and forget about the rest. something like this: public class SomeController { [PersistInUserSettings] public string LastPostUserRead { get; set; } } I don't like the LastPostUserRead to be of type "UserSetting", I like it to be a normal property so that later I can assign to it like: LastPostUserRead = "Post 1"; and not like: LastPostUserRead.SetValue("Post 1"); Any idea on how to implement it (without Reflection.Emit) in monotouch?

• Refinery CMS (Rails): Creating a plugin or plugins with multiple models and relationships

  - by jklina

  My goal is to create a way for an admin to create two models in the Refinery admin: Campaigns and Videos I would like to have it setup so that a Campaign has many Videos and that each Video belongs to a Campaign. Both Videos and Campaigns will have a title, description, and a preview image. I'm not certain of the best way to go about this. Is it possible to setup two plugins and form a relationship between the two? Or, should I create one plugin with both models. If someone could point me in the right direction or a good example of a solution to a similar problem, I would be grateful. Thank you for looking!

• C# How can I tell if an IEnumerable is Mutable?

  - by Logan

  I want a method to update certain entries of an IEnumerable. I found that doing a foreach over the entries and updating the values failed as in the background I was cloning the collection. This was because my IEnumerable was backed by some LINQ-SQL queries. By changing the method to take a List I have changed this behavior, Lists are always mutable and hence the method changes the actual objects in the list. Rather than demand a List is passed is there a Mutable interface I can use? // Will not behave as consistently for all IEnumerables public void UpdateYesterday (IEnumerable<Job> jobs) { foreach (var job : jobs) { if (job.date == Yesterday) { job.done = true; } } }

• Facebox window closes after submit

  - by Kim Andersen

  Hi all I have a question regarding Facebox. When I click a certain link on my page, the Facebox modal window opens just fine. But inside this modal window I'd like to have a form that users can submit. When the users click the submit-button, the whole page refreshes, and my Facebox-window is closed. This makes sense to me, but I'd like it to work differently. I want to give the user a confirmation, inside of the modal window, after they have submitted the form. So when a user clicks the submit-button, a confirmation should be showed inside og the modal-window. Anybody know if this is possible? I hope that you understand my question :) Best regards Kim Andersen

• Embedding an offline Dashcode application in a UIWebView in an iPhone application

  - by Nimrod

  In order words, can anyone tell me the basics of how to create a "hybrid" iPhone application? I want to load the web content (the Dashcode app itself) from the native application's application bundle. I've gotten this to partially work, but some content won't display and it otherwise seems like Dashcode is assuming a certain Safari environment or something that I don't seem to have in my UIWebView. Can anyone provide a link to some sample code that embeds a Dashcode project into a cocoa touch Xcode project? (I did search around Google for a bit trying to find something and I failed to come up with anything worthwhile, except for some books that I might eventually buy if the approach seems worthwhile.)

• Formula for calculating Exotic wagers such as Trifecta and Superfecta

  - by JohnnyCantCode

  I am trying to create an application that will calculate the cost of exotic parimutuel wager costs. I have found several for certain types of bets but never one that solves all the scenarios for a single bet type. If I could find an algorithm that could calculate all the possible combinations I could use that formula to solve my other problems. Additional information: I need to calculate the permutations of groups of numbers. For instance; Group 1 = 1,2,3 Group 2 = 2,3,4 Group 3 = 3,4,5 What are all the possible permutation for these 3 groups of numbers taking 1 number from each group per permutation. No repeats per permutation, meaning a number can not appear in more that 1 position. So 2,4,3 is valid but 2,4,4 is not valid. Thanks for all the help.

• WCF ValidationFault

  - by RandomNoob

  I'm using Validation Application Block - Enterprise Library to validate parameters sent to my WCF Service operations. For instance, a certain operation requires the parameter to either be a 1 or 6, like so: [OperationContract(Name="GetEmployeesByRegion")] [FaultContract(typeof(ValidationFault))] List<Employees> GetEmployeesByRegion([DomainValidator(1,6)]int regionId); This works just fine i.e the validation fault occurs however, when the service is invoked by the client, a generic System.ServiceModel.FaultException is thrown. An the message indicates: "The creator of this fault did not specify a reason." Now, I could check the parameters myself before the service cal and throw a custom fault but that seems to defeat the purpose of attribute based validation of parameters using the Validation Application Block. Is there anyway to customize the error returned by the validation Fault? It is also possible I'm doing something completely wrong. I just want the caller to know that he/she should have passed in a 1 or 6 in the exception message. Is this possible?

• Webservice Jira gives: Error: No such operation 'getIssuesFromJqlSearch' from Jira 4.01

  - by Robert

  When I use the Webservice of Jira, I need to use the method getIssuesFromJqlSearch to describe a certain (JQL) Query. But it returns me "No such operation 'getIssuesFromJqlSearch'". Is this method in Jira 4.01 not implemented yet? BTW: I need a method to get all Issues from one specific project, without creating filters first. This was my first way to find a workaround, because there is no function getIssuesFromProject. If there is no way to fix the problem with the JQL method, I try to take RSS XML View with the URL jql statement like SearchRequest.xml?jqlQuery=project+%3D+Testproject&tempMax=1000. But this is not my favorite.

• How to access Google Maps API v3 marker's DIV and it's pixel position?

  - by Ray Yun

  Instead of google maps api's default info window, I'm going to use other jquery tooltip plugin over marker. So I need to get marker's DIV and its pixel position. But couldn't get it because there are no id or class for certain marker. Only I can access map canvas div from marker object and undocumented pixelBounds object. How can I access marker's DIV? Where can I get DIV's pixel position? Can I convert lat-lng position to pixel values?

  Hi all, i have a website in which i am trying to position (using CSS) a certain on the page. the is absolutely positioned and is located inside a relatively positioned paernt . on firefox and even IE it looks ok but on Safari, things get messy and it shows 5 pixels lower than it should. i have tried to figure out for days now what is wrong there but cannot seem to see it. you can find an example link to the problematic page here: http://yaronattar.com/index.php?option=com_content&view=article&id=117:the-new-lovers-2010&catid=51:the-new-lovers-2010&Itemid=242 the problematic is the one conaining the "previous/next" navigation at the bottom right corner of the page. anyone sees what is causing the trouble here? thanks

• Device Driver IRQL and Thread/Context Switches

  - by Christian Hoglund

  Hi, I'm new to Windows device driver programming. I know that certain operations can only be performed at IRQL PASSIVE_LEVEL. For example, Microsoft have this sample code of how to write to a file from a kernel driver: if (KeGetCurrentIrql() != PASSIVE_LEVEL) return STATUS_INVALID_DEVICE_STATE; Status = ZwCreateFile(...); My question is this: What is preventing the IRQL from being raised after the KeGetCurrentIrql() check above? Say a context or thread swithch occurs, couldn't the IRQL suddenly be DISPATCH_LEVEL when it gets back to my driver which would then result in a system crash? If this is NOT possible then why not just check the IRQL in the DriverEntry function and be done with it once for all?

• How to draw a 3D donut chart in OpenGL?

  - by paulbeesley

  I would like to draw a chart in OpenGL similar to the donut graph at the bottom-right of this example. I have experience with drawing 2D charts such as the main chart in the example but what confuses me about the one I want to draw is the correct type of primitive to use when drawing the 3D chart. I have considered using GL_QUAD_STRIP and GL_POLYGON but neither seem quite right for the task. Where should I begin? I will be using JOGL with Java to draw the chart, if that helps at all. Also, I don't necessarily need to extrude certain slices of the chart as shown in the example.

• C#, Lotus Interop: Getting Message Information

  - by tsilb

  I'm using Interop.Domino.dll to retrieve E-mails from a Lotus "Database" (Term used loosely). I'm having some difficulty in retrieving certain fields and wonder how to do this properly. I've been using NotesDocument.GetFirstItem to retrieve Subject, From and Body. My issues in this regard are thus: How do I retrieve Reply-To address? Is there a list of "Items" to get somewhere? I can't find it. How do I retrieve friendly names for From and Reply-To addresses? When I retrieve Body this way, it's formatted wierdly with square bracket sets ([]) interspersed randomly across the message body, and parts of the text aren't where I expect them. Related code: string ActualSubject = nDoc.GetFirstItem("Subject").Text, ActualFrom = nDoc.GetFirstItem("From").Text, ActualBody = nDoc.GetFirstItem("Body").Text;

• IPv6 multicast addresses: Is the Group ID field effectively 112 bits or 32 bits?

  - by Jeremy Friesner

  Hi all, I'm trying to understand the rules for choosing an IPv6 multicast address Group ID, and the RFC seems somewhat inconsistent. For example, in RFC 2373 section 2.7 this diagram is shown: | 8 | 4 | 4 | 112 bits | +------ -+----+----+---------------------------------------------+ |11111111|flgs|scop| group ID | +--------+----+----+---------------------------------------------+ ... but then in section 2.7.2 it shows this: | 8 | 4 | 4 | 80 bits | 32 bits | +------ -+----+----+---------------------------+-----------------+ |11111111|flgs|scop| reserved must be zero | group ID | +--------+----+----+---------------------------+-----------------+ So my question is, are the upper 80 bits of the Group ID field usable or not? If they are usable, is it only under certain circumstances (e.g. when using non-Ethernet networking technology?) What problems should I expect to experience if I set these bits when multicasting over an Ethernet LAN?

• ASP.NET MVC Class level custom data-annotation and ModelState keys

  - by Neil

  Hi, I have custom class level validation attribute, inheriting from ValidationAttribute, on my model. How come it doesn't register a key in the ModelState when its IsValid is false? I can see the the error message in the ModelState.Values collection, but the ModelState.Keys collection only shows an empty string "". Can I provide a key for it - presumably this is because its not assigned to a property? I wanna be able to use ModelState.Remove in my controller to remove this error upon a certain condition, but I have no Key! Any ideas?

• Using truncate table alongside Hibernate?

  - by Marcus

  Is it OK to truncate tables while at the same time using Hibernate to insert data? We parse a big XML file with many relationships into Hibernate POJO's and persist to the DB. We are now planning on purging existing data at certain points in time by truncating the tables. Is this OK? It seems to work fine. We don't use Hibernate's second level cache. One thing I did notice, which is fine, is that when inserting we generate primary keys using Hibernate's @GeneratedValue where Hibernate just uses a key value one greater than the highest value in the table - and even though we are truncating the tables, Hibernate remembers the prior value and uses prior value + 1 as opposed to starting over at 1. This is fine, just unexpected. Note that the reason we do truncate as opposed to calling delete() on the Hibernate POJO's is for speed. We have gazillions of rows of data, and truncate is just so much faster.

• Forcing a mixed ISO-8859-1 and UTF-8 multi-line string into UTF-8

  - by knorv

  Consider the following problem: A multi-line string $junk contains some lines which are encoded in UTF-8 and some in ISO-8859-1. I don't know a priori which lines are in which encoding, so heuristics will be needed. I want to turn $junk into pure UTF-8 with proper re-encoding of the ISO-8859-1 lines. Also, in the event of errors in the processing I want to provide a "best effort result" rather than throwing an error. My current attempt looks like this: $junk = &force_utf8($junk); sub force_utf8 { my $input = shift; my $output = ''; foreach my $line (split(/\n/, $input)) { if (utf8::valid($line)) { utf8::decode($line); } $output .= "$line\n"; } return $output; } While this appears to work I'm certain this is not the optimal solution. How would you improve my force_utf8(...) sub?

• pyglet and animated gif

• SSRS 2005 Matrix and border styles when exporting to XLS

  - by Mufasa

  The Matrix in SSRS (SQL Server Reporting Services 2005) seems to have issues with certain the border styles when exporting to XLS (but not PDF or web view; maybe other formats, not sure?). For example: Create a matrix and set the Matrix border style to Black Solid 1px, but all 4 of the cells to have a border style of Black None 1px. When viewed via the ASP.NET control, it looks correct. But after export to XLS, it creates borders around all of the header cells (column and row headers, and the top left cell), and even the right most data column. But all the cells in the middle of the report correctly have no border set. Update: If the Matrix borders are set to None, then the borders on the cells don't show up in XLS. So, how do you set an outer border around the Matrix, but not have it apply the 'all sides' border to every cell that touches the edge of the Matrix when exported to Excel?

• How does GCC compile applications that reference a static library

  - by technobrat

  I've read that the gcc compiler can perform certain optimization when compiling an application that references a static library, for instance - it will "pull" in only that code from the static library that the application depends upon. This helps keep the size of the application's executable to a minimum if portions of the static library are not being used by the app. 1) Is this true? 2) How does GCC know what code from the static library the application is actually using? Does it only look t the header files that are included (directly and indirectly) in the application and then pull code accordingly? Or does it actually look at what methods from the static library are being called?

• Multi-statement Table Valued Function vs Inline Table Valued Function

  - by AndyC

  ie: CREATE FUNCTION MyNS.GetUnshippedOrders() RETURNS TABLE AS RETURN SELECT a.SaleId, a.CustomerID, b.Qty FROM Sales.Sales a INNER JOIN Sales.SaleDetail b ON a.SaleId = b.SaleId INNER JOIN Production.Product c ON b.ProductID = c.ProductID WHERE a.ShipDate IS NULL GO versus: CREATE FUNCTION MyNS.GetLastShipped(@CustomerID INT) RETURNS @CustomerOrder TABLE (SaleOrderID INT NOT NULL, CustomerID INT NOT NULL, OrderDate DATETIME NOT NULL, OrderQty INT NOT NULL) AS BEGIN DECLARE @MaxDate DATETIME SELECT @MaxDate = MAX(OrderDate) FROM Sales.SalesOrderHeader WHERE CustomerID = @CustomerID INSERT @CustomerOrder SELECT a.SalesOrderID, a.CustomerID, a.OrderDate, b.OrderQty FROM Sales.SalesOrderHeader a INNER JOIN Sales.SalesOrderHeader b ON a.SalesOrderID = b.SalesOrderID INNER JOIN Production.Product c ON b.ProductID = c.ProductID WHERE a.OrderDate = @MaxDate AND a.CustomerID = @CustomerID RETURN END GO Is there an advantage to using one over the other? Is there certain scenarios when one is better than the other or are the differences purely syntactical? I realise the 2 example queries are doing different things but is there a reason I would write them in that way? Reading about them and the advantages/differences haven't really been explained. Thanks

• Is there a difference between long-polling and using Comet

  - by Saif Bechan

  I am implementing a system where I need real-time updates. I have been looking at certain scenarios and among all was Comet. Implementing this I do not see any way this is different from traditional long-polling. In both cases you have to send a request, and then the server send a response back. In the browser you interpret the response and then you start a new request. So why should I use comet if in both cases I need to open and close connections.

• How can I stop SQL Server Reporting Services 2008 going to sleep?

  - by Nick

  I have SSRS 2008 set-up on a server. All works fine except that if left inactive for a length of time the next time a request is made to the server it takes a long time for it to service it. I think this is to do with the worker process being shutdown after being idle for a certain length of time. However, as SSRS 2008 isn't managed through IIS I can't find any settings that I can adjust to stop this from happening. In IIS I'd go to the Performance tab of the Application Pool Properties and choose not to shutdown the worker process. How can I do this for SSRS 2008?
