  • How to get an ASP.NET MVC Ajax response to redirect to new page instead of inserting view into Updat

    - by Jeff Widmer
    I am using the Ajax.BeginForm to create a form the will do an ajax postback to a certain controller action and then if the action is successful, the user should get redirected to another page (if the action fails then a status message gets displayed using the AjaxOptions UpdateTargetId). using (Ajax.BeginForm("Delete", null, new { userId = Model.UserId }, new AjaxOptions { UpdateTargetId = "UserForm", LoadingElementId = "DeletingDiv" }, new { name = "DeleteForm", id = "DeleteForm" })) { [HTML DELETE BUTTON] } If the delete is successful I am returning a Redirect result: [Authorize] public ActionResult Delete(Int32 UserId) { UserRepository.DeleteUser(UserId); return Redirect(Url.Action("Index", "Home")); } But the Home Controller Index view is getting loaded into the UpdateTargetId and therefore I end up with a page within a page. Two things I am thinking about: Either I am architecting this wrong and should handle this type of action differently (not using ajax). Instead of returning a Redirect result, return a view which has javascript in it that does the redirect on the client side. Does anyone have comments on #1? Or if #2 is a good solution, what would the "redirect javascript view" look like?

  • What could cause "Connection Interrupted" on LocalHost when debugging in ASP.NET

    - by Jeff Dalley
    I'm trying to run a freshly created ASP.NET Website using C#, however when I do so it launches FireFox and attempts to connect to http://localhost:1295/WebSite1/Default.aspx (for example), but after about 10-15 seconds it displays a "Connection Interrupted - The connection to the server was reset while the page was loading." Error. This issue is also present with older ASP.NET C# pages/Web Services I've built in the past, nothing is actually running off the ASP.NET Development server. I am using: Windows XP Pro SP2, Visual Studio 2008 For reference I have SQL Server 2005 Developer Edition installed as well. I have tried: Browsing it with IE instead of Mozilla Trying 2.0 framework instead of 3.5 Reinstalling Visual Studio 2008 This problem seems so trivial the more I think about it, but I havn't been able to work it out just yet! Appreciate any help on the matter.

  • Why does one of these statements compile in Scala but not the other?

    - by Jeff
    (Note: I'm using Scala 2.7.7 here, not 2.8). I'm doing something pretty simple -- creating a map based on the values in a simple, 2-column CSV file -- and I've completed it easily enough, but I'm perplexed at why my first attempt didn't compile. Here's the code: // Returns Iterator[String] private def getLines = Source.fromFile(csvFilePath).getLines // This doesn't compile: def mapping: Map[String,String] = { Map(getLines map { line: String => val pairArr = line.split(",") pairArr(0) -> pairArr(1).trim() }.toList:_*) } // This DOES compile def mapping: Map[String,String] = { def strPair(line: String): (String,String) = { val pairArr = line.split(",") pairArr(0) -> pairArr(1).trim() } Map(getLines.map( strPair(_) ).toList:_*) } The compiler error is CsvReader.scala:16: error: value toList is not a member of (St ring) = (java.lang.String, java.lang.String) [scalac] possible cause: maybe a semicolon is missing before `value toList'? [scalac] }.toList:_*) [scalac] ^ [scalac] one error found So what gives? They seem like they should be equivalent to me, apart from the explicit function definition (vs. anonymous in the nonworking example) and () vs. {}. If I replace the curly braces with parentheses in the nonworking example, the error is "';' expected, but 'val' found." But if I remove the local variable definition and split the string twice AND use parens instead of curly braces, it compiles. Can someone explain this difference to me, preferably with a link to Scala docs explaining the difference between parens and curly braces when used to surround method arguments?

  • Overloading framework methods in objective-c, or retaining local changes with framework updates.

    - by Jeff B
    I am using cocos2d to build an iPhone game. It's mostly done, but along the way I came across some things that I would like to handle better. I am fairly new to Objective C, and honestly I do more Perl scripting in my day-to-day job than anything, so my C skills are a little rusty. One of them is the fact that I have modified cocos2d files for some specific cases in my game. However, when I update to a new version, I have to manually pull my changes forward. So, the question is, what is the best way to deal with this? Some options I have thought of: Overload/redefine the cocos2d classes. I was under the impression that I cannot overload existing class functions, so I don't think this will work. Create patches that I re-apply after library updates. I don't think this will work as the new files won't necessarily be the same as the old ones, and if they were, I could just copy the whole file forward. Turn in my changes to Cocos2d. Not an option as my changes are very specific to my application. Am I missing something obvious? UPDATE: I will explain what I am doing to be more clear. Cocos2d has a CCNode object, which can contain children, etc. I added a shadow, which is very similar to a child, but handled a little differently. The shadow has an offset from the parent, and translates with it's parent, rotates around it's own center when the parent rotates, etc. The shadow is not included as a true child, however, so given the correct z-index, the shadows can render under ALL other objects, but still move with the parent. To do this I added addShadow functions to CCNode, and modified the setPosition and setRotate functions to move the shadowSprite: CCNode.m: -(id) init { if ((self=[super init]) ) { ... shadowSprite_ = nil; ... } } ... -(BOOL) addShadow: (CCNode*) child offset: (CGPoint) offset { shadowSprite_ = child; shadowSprite_.position = CGPointMake(position_.x+offset.x, position_.y+offset.y); return YES; } ... -(void) setRotation: (float)newRotation { rotation_ = newRotation; isTransformDirty_ = isInverseDirty_ = YES; if(shadowSprite_) { [shadowSprite_ setRotation: newRotation]; } } There is more, of course, including the prototypes in the .h file, but that is the basics. I don't think I need shadowSprite to be a property, because I don't need to access it after it has been added.

  • Managing many objects at once.

    - by Jeff
    Hi, I want to find a way to efficiently keep track of a lot of objects at once. One practical example I can think of would be a particle system. How are hundreds of particles kept track of? I think I'm on the right track, I found the term 'instancing' and I also learned about flyweights. Hopefully somebody can shed some light on this and share some techniques with me. Thanks.

  • parse content away from structure in a binary file

    - by Jeff Godfrey
    Using C#, I need to read a packed binary file created using FORTRAN. The file is stored in an "Unformatted Sequential" format as described here (about half-way down the page in the "Unformatted Sequential Files" section): http://www.tacc.utexas.edu/services/userguides/intel8/fc/f_ug1/pggfmsp.htm As you can see from the URL, the file is organized into "chunks" of 130 bytes or less and includes 2 length bytes (inserted by the FORTRAN compiler) surrounding each chunk. So, I need to find an efficient way to parse the actual file payload away from the compiler-inserted formatting. Once I've extracted the actual payload from the file, I'll then need to parse it up into its varying data types. That'll be the next exercise. My first thoughts are to slurp up the entire file into a byte array using File.ReadAllBytes. Then, just iterate through the bytes, skipping the formatting and transferring the actual data to a second byte array. In the end, that second byte array should contain the actual file contents minus all the formatting, which I'd then need to go back through to get what I need. As I'm fairly new to C#, I thought there might be a better, more accepted way of tackling this. Also, in case it's helpful, these files could be fairly large (say 30MB), though most will be much smaller...

  • VS2010 Publish Profiles -- Where are they stored?

    - by Jeff S
    We have set up a few Publish Profiles that are used to deploy web apps to various servers, and it all works great with 1-click deployment. However, w find that even though the entire solution is under source control (svn), the profiles do not seem to be carried over, so we need to re-create the profiles on each developer's machine manually. It seems, since the profiles only exist for the solution currently loaded, that they must be stored in the solution files somewhere, but they do not carry over when someone else does an update to pull down the code. I'm guessing whatever file they're in is one we aren' covering in the source control project, but I haven't been able to figure out which one. Someone must know where the Publish Profiles are stored -- is there any way to copy them from machine to machine so we don't have to retype them for each developer?

  • Entity Framework Generic Repository Error

    - by Jeff Ancel
    I am trying to create a very generic generics repository for my Entity Framework repository that has the basic CRUD statements and uses an Interface. I have hit a brick wall head first and been knocked over. Here is my code, written in a console application, using a Entity Framework Model, with a table named Hurl. Simply trying to pull back the object by its ID. Here is the full application code. using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Data.Objects; using System.Linq.Expressions; using System.Reflection; using System.Data.Objects.DataClasses; namespace GenericsPlay { class Program { static void Main(string[] args) { var hs = new HurlRepository(new hurladminEntity()); var hurl = hs.Load<Hurl>(h => h.Id == 1); Console.Write(hurl.ShortUrl); Console.ReadLine(); } } public interface IHurlRepository { T Load<T>(Expression<Func<T, bool>> expression); } public class HurlRepository : IHurlRepository, IDisposable { private ObjectContext _objectContext; public HurlRepository(ObjectContext objectContext) { _objectContext = objectContext; } public ObjectContext ObjectContext { get { return _objectContext; } } private Type GetBaseType(Type type) { Type baseType = type.BaseType; if (baseType != null && baseType != typeof(EntityObject)) { return GetBaseType(type.BaseType); } return type; } private bool HasBaseType(Type type, out Type baseType) { Type originalType = type.GetType(); baseType = GetBaseType(type); return baseType != originalType; } public IQueryable<T> GetQuery<T>() { Type baseType; if (HasBaseType(typeof(T), out baseType)) { return this.ObjectContext.CreateQuery<T>("[" + baseType.Name.ToString() + "]").OfType<T>(); } else { return this.ObjectContext.CreateQuery<T>("[" + typeof(T).Name.ToString() + "]"); } } public T Load<T>(Expression<Func<T, bool>> whereCondition) { return this.GetQuery<T>().Where(whereCondition).First(); } public void Dispose() { if (_objectContext != null) { _objectContext.Dispose(); } } } } Here is the error that I am getting: System.Data.EntitySqlException was unhandled Message="'Hurl' could not be resolved in the current scope or context.

  • IE6 rendering bug. Some parsed <li> elements are losing their closing tags.

    - by Jeff Fohl
    I have been working with IE6 for many years [sob], but have never seen this particular bug before, and I can't seem to find a reference to it on the Web. The problem appears to be with how IE6 is parsing the HTML of a nested list. Even though the markup is correct, IE6 somehow munges the code when it is parsed, and drops the closing tags of some of the <li> elements. For example, take the following code: <!DOCTYPE html> <head> <title>My Page</title> </head> <body> <div> <ul> <li><a href=''>Child A</a> <div> <ul> <li><a href=''>Grandchild A</a></li> </ul> </div> </li> <li><a href=''>The Child B Which Is Not A</a> <div> <ul> <li><a href=''>Grandchild B</a></li> <li><a href=''>Grandchild C</a></li> </ul> </div> </li> <li><a href=''>Deep Purple</a></li> <li><a href=''>Led Zeppelin</a></li> </ul> </div> </body> </html> Now take a look at how IE6 renders this code, after it has run it through the IE6 rendering engine: <HTML> <HEAD> <TITLE>My Page</TITLE></HEAD> <BODY> <DIV> <UL> <LI><A href="">Child A</A> <DIV> <UL> <LI><A href="">Grandchild A</A> </LI> </UL> </DIV> <LI><A href="">The Child B Which Is Not A</A> <DIV> <UL> <LI><A href="">Grandchild B</A> <LI><A href="">Grandchild C</A> </LI> </UL> </DIV> <LI><A href="">Deep Purple</A> <LI><A href="">Led Zeppelin</A> </LI> </UL> </DIV> </BODY> </HTML> Note how on some of the <li> elements there are no longer any closing tags, even though it existed in the source HTML. Does anyone have any idea what could be triggering this bug, and if it is possible to avoid it? It seems to be the source of some visual display problems in IE6. Many thanks for any advice.

  • Does the order of columns matter in a group by clause?

    - by Jeff Meatball Yang
    If I have two columns, one with very high cardinality and one with very low cardinality (unique # of values), does it matter in which order I group by? Here's an example: select dimensionName, dimensionCategory, sum(someFact) from SomeFact f join SomeDim d on f.dimensionKey = d.dimensionKey group by d.dimensionName, -- large number of unique values d.dimensionCategory -- small number of unique values Are there situations where it matters?

  • Jquery $().each method obscures 'this' keyword

However, I would like This[1] to refer to the containing class... How can I refer to the containing class from within the jQuery loop?

  • T-SQL error object exists when separated in if/else blocks

    I get the error: Msg 2714, Level 16, State 1, Line 16 There is already an object named '#mytemptable' in the database. There are ways around it, but wonder why this happens. Seems like SQL Server is verifying both blocks of the if/else statement? declare @choice int select @choice = 1 if @choice = 1 begin select 'MyValue = 1' AS Pick into #my_temp_table end else begin select 'MyValue <> 1' AS Pick into #my_temp_table end select * from #temptable drop table #temptable If the tables have different names, it works. Or if I create the temp table and use Insert Into... statements that works as well.

  • Unattended Install of SQL Server 2005 Express with LOCAL Server InstanceName

    - by Jeff
    I'm creating an install package using InnoSetup and installing SQL Server 2005 Express. Here's the code below that appears in my RUN section: Filename: "{app}\SQL Server 2005 Express\SQLEXPR.exe" ; Parameters: "-q /norebootchk /qn reboot=ReallySuppress addlocal=all INSTANCENAME=(LOCAL) SCCCHECKLEVEL=IncompatibleComponents:1;MDAC25Version:0 ERRORREPORTING=2 SQLAUTOSTART=1 SAPWD=passwordhere SECURITYMODE=SQL"; WorkingDir: {app}\SQL Server 2005 Express; StatusMsg: Installing Microsoft SQL Server 2005 Express... Please Wait...;Check:SQLVerifyInstall What I'm trying to accomplish is have the SQL Server package install but only have the instance name itself reference the name of the machine name and nothing more. What I'm receiving instead is a named instance instead of local such as MachineName\SQLEXPRESS which is not what I want to receive. I need a local instance instead of a named instance due to the way my code is written to be able to install and talk with the databases in question. I would change it, trust me, were it not the fact that this install package is a replacement to a previous package that used the MSDE installer. I have to be able to support both through code. Any suggestions are welcome but a clear and concise method to get the installer to quietly install using only the machine name is my main goal. Thanks for the help and support!

  • j2ME setLocationListener()

    - by Jeff Catania
    I'm programming a GPS tracking system using the Motorola i335 running on Sprint's IDEN network. I'm using the javax.microedition.location api to find the GPS coordinates. To set up the updating, you use the [setLocationListener][1] method. I originally tried passing (listener,2,1,1). However there was too many invalid locations being received (where the GPS could not get the fix in the specified time), so I changed the parameters to (listener, 20, 20, 1). Now the system barely throws any invalid locations. My goal is to get the fastest number of updates that are realistic. Have any of you found a happy medium for parameters of this method?

  • Should we deploy a Webkit browser for our intranet applications?

    - by Jeff Meatball Yang
    At my place of employment, we are increasingly finding it difficult to develop for IE, which was historically the easiest browser to target, from an intranet-app point of view. It was already deployed. It already understood NTLM authentication, thus well integrated with our domain-level security. It had neat, albeit non-standard features such as XMLDOM and XmlHTTP. Now, we are increasingly irritated by issues presented by IE: There are several versions: IE 7, 8, and soon 9 beta, which all have slightly different issues related to performance, functionality (especially re:security and zones), and aesthetics. IE 7 and 8 are slower than Webkit-based browsers. Period. There are technology limitations such as missing canvas element, CSS bugs, etc. that make it hard to use 3rd party packages or even consistently write code across IE versions. Users are increasingly using Firefox or Chrome, even for intranet use. Does anyone have experience with making a transition? Any advice would be welcome.

  • What is the equivalent to IScriptControl for Web.UI.Page?

    - by Jeff Dege
    We've been using IScriptControl to tie javascript objects to our UserControls and ServerControls, and it's worked fine. The problem is that ASP.NET seems to provide no method to tie a javascript object to a Page. Up to now, we've been putting plain functions in the global namespace, but I am developing a serious allergy to that practice. It'd be easy enough to wrap our functions into a javascript class, and to include the javascript file on the page, but how to instantiate the object, how to reference it from callback events, and how to pass data to it from the code-behind, I haven't figured out. Or rather, the methods we've been using up to now (hidden fields, emitted javascript strings, etc.), really bug me. Anyone have better ideas?

  • Silverlight Unit Testing Framework running tests in external class library

    - by Jonas Follesø
    I'm currently looking into different options for unit testing Silverlight applications. One of the frameworks available is the Silverlight Unit Test Framework from Microsoft (developed primary by Jeff Wilcox, http://www.jeff.wilcox.name/2010/05/sl3-utf-bits/). One of the scenarios I'm looking into is running the same tests on both Silverlight 3 (PC) and Windows Phone 7. The Silverlight Unit Test Framework (SLUT) runs on both PC and phone. To prevent having to copy or link files I would like to put my tests into a shared test library, that can be loaded by either a WP7 application using the SLUT, or a Silverlight 3 application using SLUT. So my question is: will SLUT load unit tests defined in a referenced class library, or only in the executing assembly?
