    i am trying to do a basic column chart. i have looked the examples but not sure why i do not see any graph (lines). I can see the title and subtitle appear an no javascript errors in firebug. any help please $(function () { var chart; $(document).ready(function() { chart = new Highcharts.Chart({ chart: { renderTo: 'container', type: 'column', events: { load: requestData } }, title: { text: 'Some title' }, subtitle: { text: 'subtitle' }, xAxis: { categories: [], title: { text: null } }, yAxis: { min: 0, title: { text: 'y-Axis', align: 'high' } }, tooltip: { formatter: function() { return ''+ this.series.name +': '+ this.y +' '; } }, plotOptions: { bar: { dataLabels: { enabled: true } } }, legend: { layout: 'vertical', align: 'right', verticalAlign: 'top', x: -100, y: 100, floating: true, borderWidth: 1, backgroundColor: '#FFFFFF', shadow: true }, credits: { enabled: false }, series:[] }); }); function requestData() { $.ajax({ url: 'test.json', success: function(data) { options.series[0].push(data); chart.redraw(); }, cache: false }); } }); my json input file is below [ { name: 'name1', y: [32.6,16.6,1.5] }, { name: 'name2', y: [6.7,0.2,0.6] }, { name: 'name3', y: [1,3.7,0.7] }, { name: 'name4', y: [20.3,8.8,9.5] },{ name: 'name5', y: [21.5,10,7.2] }, { name: 'name6', y: [1.4,1.8,3.7] }, { name: 'name7', y: [8.1,0,0] }, { name: 'name8', y: [28.9,8.9,6.6] } ]

  • How does one get rid of fishy behavior in Windows?

    - by Tom Wijsman
    After I had boot my computer this morning there suddenly flooded water from the top of the screen, after which some fishes dropped into it. Now I can barely see what I am doing because the water distorts the view. Sometimes the fish follow the cursor so I need to move it away or wait for the fish to mind their own business. This makes it very annoying to use my system. What have I tried? Reboot the system. This caused the water to deplete from the desktop. Upon reboot, the screen was refilled with water and fishes. Attach another monitor. Same problem, fills that monitor as well and gives me extra fish. Clicking the fish. Makes them turn direction. Right clicking the fish. Changes color of the fish, not really useful. I'm locked out of changing the background or screen saver settings. Hence, I had to post the lady below... Safe mode doesn't save me from the fishes. It does give me another background there, but I can't screenshot easily. Other user accounts experience this as well. The Guest account seems to experience more fish than the other accounts. Using HijackThis, OTL Timekeeper List, Syninternal Autoruns, RootKitRevealer, ShellExView and similar tools I can't seem to find any entries that could be it, the Sysinternals tools show everything as verified. I'm suspecting this to be a driver problem. Randomly removing drivers doesn't seem to alleviate the problem. When removing the Graphics Drivers, it makes my screen black. While that could be considered the solution, it's not what I want. Changing the time / date settings does also not seem to affect the fishes. Changing the time a few years in the future, I would have expected the fishes to be dead. But, the same fishes are still there... They simply won't die! Tried to get used to them. They are really bothering me, looks like they require food. I don't know how to give them food, but apparently they get it elsewhere during reboot... Tried to disable my mouse pointer and use the keyboard. This works, they now swim around more randomly. They do put their attention to huge changes on the screen, so I need to type slow. Or otherwise I can't see what I'm tying exactly. Hold my laptop upside down. This seems to affect the water and fishes, but the water stays in the screen. They seem super resistant against water sickness and confusion though... What does the problem look like? What do I need? A way to get rid of these fishes on my screen forever, they are really annoying me a lot and I'm about to crack the screen to see if that makes them escape. Do you have any idea why this problem is occurring? What are my considerations? Buying an USB fish tank could make the fish leave the screen, I am uncertain though whether the fish could leave the screen through the USB cable. Using the FISh (programming language) which seems to provide EXPRESSIVE POWER and EFFICIENT EXECUTION, I can however not find any examples on how to remove fish. What are my Specifications? I'm using a Sony Vaio Fishy laptop. Sony VAIO VGN-Fishy, VAIO. Processor: 1337 MHz, Intel Core 2 Duo, T5432, 1 MB, Intel PM965 Express, 667 MHz.

  • Not able to use 7-Zip to compress stdin and output with stdout?

  • Sharing sessions across applications using the ASP.NET Session State Service

    - by Dan
    I am trying to share sessions between two web applications, both hosted on the same server. One is a .net 2.0 web forms application the other is as .net 3.5 MVC2 application. Both apps have their session set up like this: <sessionState mode="StateServer" stateConnectionString="tcpip=127.0.0.1:42424" /> In the webform application I am posting the the session key to the MVC app: protected void LinkButton1_Click(object sender, EventArgs e) { Session["myvariable"] = "dan"; string sessionKey = HttpContext.Current.Session.SessionID; //Followed by some code that posts sessionKey to the other application } I then recieve it in the MVC application and try use the same session like this: [HttpPost] public void Recieve(string sessionKey ) { var manager = new SessionIDManager(); bool redirected; bool IsAdded; manager.SaveSessionID(HttpContext.ApplicationInstance.Context, Id, out redirected, out IsAdded); var sessionKey = Session["myvariable"]; } The key is being posted but the session does not seem to get loaded in the MVC app, i.e. sessionKey is null. Can what I am trying to do be done?

  • Is there a way to create a SyndicationFeed from a String?

    - by Roberto Bonini
    Hi, I'm trying to recreate a SyndicationFeed object (System.ServiceModel.Syndication) from XML data that has been stored locally. If I were working with XMLDocument, this would be easy.I'd call LoadXml(string). The SyndicationFeed will only load from an XMLReader. The XMLReader will only take a Stream or another XMLReader or a TextReader. Since XMLDocument will load a string, I've tried to do this as follows (in the form of a Extension Method): public static SyndicationFeed ToSyndicationFeed(this XmlDocument document) { Stream thestream = Stream.Null; XmlWriter thewriter = XmlWriter.Create(thestream); document.WriteTo(thewriter); thewriter.Flush(); XmlReader thereader = XmlReader.Create(thestream); SyndicationFeed thefeed = SyndicationFeed.Load(thereader); return thefeed; } I can't get this to work. The Stream is always empty even though the XMLDocument is populated with the Feed to be loaded into the SyndicationFeed. Any help or pointers you can give would be most helpful. Thanks, Roberto

  • What makes static initialization functions good, bad, or otherwise?

    - by Richard Levasseur
    Suppose you had code like this: _READERS = None _WRITERS = None def Init(num_readers, reader_params, num_writers, writer_params, ...args...): ...logic... _READERS = new ReaderPool(num_readers, reader_params) _WRITERS = new WriterPool(num_writers, writer_params) ...more logic... class Doer: def __init__(...args...): ... def Read(self, ...args...): c = _READERS.get() try: ...work with conn finally: _READERS.put(c) def Writer(...): ...similar to Read()... To me, this is a bad pattern to follow, some cons: Doers can be created without its preconditions being satisfied The code isn't easily testable because ConnPool can't be directly mocked out. Init has to be called right the first time. If its changed so it can be called multiple times, extra logic has to be added to check if variables are already defined, and lots of NULL values have to be passed around to skip re-initializing. In the event of threads, the above becomes more complicated by adding locking Globals aren't being used to communicate state (which isn't strictly bad, but a code smell) On the other hand, some pros: its very convenient to call Init(5, "user/pass", 2, "user/pass") It simple and "clean" Personally, I think the cons outweigh the pros, that is, testability and assured preconditions outweigh simplicity and convenience.

  • Limiting choices from an intermediary ManyToMany junction table in Django

    - by Matthew Rankin
    Background I've created three Django models—Inventory, SalesOrder, and Invoice—to model items in inventory, sales orders for those items, and invoices for a particular sales order. Each sales order can have multiple items, so I've used an intermediary junction table—SalesOrderItems—using the through argument for the ManyToManyField. Also, partial billing of a sales orders is allowed, so I've created a ForeignKey in the Invoice model related to the SalesOrder model, so that a particular sales order can have multiple invoices. Here's where I deviate from what I've normally seen. Instead of relating the Invoice model to the Item model via a ManyToManyField, I've related the Invoice model to the SalesOrderItem intermediary junction table through the intermediary junction table InvoiceItem. I've done this because it better models reality—our invoices are tied to sales orders and can only include items that are tied to that sales order as opposed to any item in inventory. I will admit that it does seem strange having the intermediary junction table of a ManyToManyField related to the intermediary junction table of another ManyToManyField. Question How can I limit the choices available for the invoice_items in the Invoice model to just the sales_order_items of the SalesOrder model for that particular Invoice? (I tried using limit_choices_to= {'sales_order': self.invoice.sales_order}) as part of the item = models.ForeignKey(SalesOrderItem) in the InvoiceItem model, but that didn't work. Am I correct in thinking that limiting the choices for the invoice_items should be handled in the model instead of in a form? Code class Item(models.Model): item_num = models.SlugField(unique=True) default_price = models.DecimalField(max_digits=10, decimal_places=2, blank=True, null=True) class SalesOrderItem(models.Model): item = models.ForeignKey(Item) sales_order = models.ForeignKey('SalesOrder') unit_price = models.DecimalField(max_digits=10, decimal_places=2) quantity = models.DecimalField(max_digits=10, decimal_places=4) class SalesOrder(models.Model): customer = models.ForeignKey(Party) so_num = models.SlugField(max_length=40, unique=True) sales_order_items = models.ManyToManyField(Item, through=SalesOrderItem) class InvoiceItem(models.Model): item = models.ForeignKey(SalesOrderItem) invoice = models.ForeignKey('Invoice') unit_price = models.DecimalField(max_digits=10, decimal_places=2) quantity = models.DecimalField(max_digits=10, decimal_places=4) class Invoice(models.Model): invoice_num = models.SlugField(max_length=25) sales_order = models.ForeignKey(SalesOrder) invoice_items = models.ManyToManyField(SalesOrderItem, through='InvoiceItem')

    Hi guys, I have another question. XMLhttpRequests haunt me. Everything is now in the database but I need this data to update my page on firt page load or reload.

  • Understanding Flash SWC's imported into Flex Builder 3 and key framed animation

    - by Hank Scorpio
    I am trying to understand what is going on in a SWC that I am importing from Flash CS4 into Flex Builder 3. Specifically I am using a SWC supplied by a Designer as the animation for a custom preloader (a subclassed DownloadProgressBar). The issue I am trying to understand is, once the FlexEvent.INIT_COMPLETE is fired, I cleanup by removing the swc by running this : removeChild(myPreloader); myPreloader = null; though even after I have removed this (which is successful, as I have checked by comparing this.numChildren before and after the call) the key framed animation still continues to run (not visibly). This has been detected by the Designer placing a trace in the time line of the animation (in Flash). Can anyone tell me why is it, that even after I have removed the animation from the subclassed DownloadProgressBar, it still keeps running ? Also, is it standard practice when importing SWCs to manage the cleanup of resources from the Flash side of things (much like releasing memory in obj-c). I find it counter intuitive that removing the child from the Flex side does not stop the animation. Any clues to this would be greatly appreciated.

  • Need help with BOOST_FOREACH/compiler bug

    - by Jacek Lawrynowicz
    I know that boost or compiler should be last to blame, but I can't see another explanation here. I'm using msvc 2008 SP1 and boost 1.43. In the following code snippet execution never leaves third BOOST_FOREACH loop typedef Graph<unsigned, unsigned>::VertexIterator Iter; Graph<unsigned, unsigned> g; g.createVertex(0x66); // works fine Iter it = g.getVertices().first, end = g.getVertices().second; for(; it != end; ++it) ; // fine std::pair<Iter, Iter> p = g.getVertices(); BOOST_FOREACH(unsigned handle, p) ; // fine unsigned vertex_count = 0; BOOST_FOREACH(unsigned handle, g.getVertices()) vertex_count++; // oops, infinite loop vertex_count = 0; BOOST_FOREACH(unsigned handle, g.getVertices()) vertex_count++; vertex_count = 0; BOOST_FOREACH(unsigned handle, g.getVertices()) vertex_count++; // ... last block repeated 7 times Iterator code: class Iterator : public boost::iterator_facade<Iterator, unsigned const, boost::bidirectional_traversal_tag> { public: Iterator() : list(NULL), handle(INVALID_ELEMENT_HANDLE) {} explicit Iterator(const VectorElementsList &list, unsigned handle = INVALID_ELEMENT_HANDLE) : list(&list), handle(handle) {} friend std::ostream& operator<<(std::ostream &s, const Iterator &it) { s << "[list: " << it.list <<", handle: " << it.handle << "]"; return s; } private: friend class boost::iterator_core_access; void increment() { handle = list->getNext(handle); } void decrement() { handle = list->getPrev(handle); } unsigned const& dereference() const { return handle; } bool equal(Iterator const& other) const { return handle == other.handle && list == other.list; } const VectorElementsList<T> *list; unsigned handle; }; Some ASM fun: vertex_count = 0; BOOST_FOREACH(unsigned handle, g.getVertices()) // initialization 013E1369 mov edi,dword ptr [___defaultmatherr+8 (13E5034h)] // end iterator handle: 0xFFFFFFFF 013E136F mov ebp,dword ptr [esp+0ACh] // begin iterator handle: 0x0 013E1376 lea esi,[esp+0A8h] // begin iterator list pointer 013E137D mov ebx,esi 013E137F nop // forever loop begin 013E1380 cmp ebp,edi 013E1382 jne main+238h (13E1388h) 013E1384 cmp ebx,esi 013E1386 je main+244h (13E1394h) 013E1388 lea eax,[esp+18h] 013E138C push eax // here iterator is incremented in ram 013E138D call boost::iterator_facade<detail::VectorElementsList<Graph<unsigned int,unsigned int>::VertexWrapper>::Iterator,unsigned int const ,boost::bidirectional_traversal_tag,unsigned int const &,int>::operator++ (13E18E0h) 013E1392 jmp main+230h (13E1380h) vertex_count++; // forever loop end It's easy to see that iterator handle is cached in EBP and it never gets incremented despite of a call to iterator operator++() function. I've replaced Itarator implmentation with one deriving from std::iterator and the issue persisted, so this is not iterator_facade fault. This problem exists only on msvc 2008 SP1 x86 and amd64 release builds. Debug builds on msvc 2008 and debug/release builds on msvc 2010 and gcc 4.4 (linux) works fine. Furthermore the BOOST_FOREACH block must be repeaded exacly 10 times. If it's repeaded 9 times, it's all OK. I guess that due to BOOST_FOREACH use of template trickery (const auto_any), compiler assumes that iterator handle is constant and never reads its real value again. I would be very happy to hear that my code is wrong, correct it and move on with BOOST_FOREACH, which I'm very found of (as opposed to BOOST_FOREVER :). May be related to: http://stackoverflow.com/questions/1275852/why-does-boost-foreach-not-work-sometimes-with-c-strings

  • Problem Binding a ObservableCollection to a ListBox in WPF/MVVM

    - by alexqs
    I'm working in some code , using wpf and starting to use mvvm. So far i have no problem, when i have one element and I have to show the values of it in the screen (binding of the specific name of the property). But now, i have to work with a property list , not knowing the names of it. So I created a class, named GClass, that only have two propierties, name and value. I created the ObservableCollection, and fill for now with direct values, and asign the view (lstview) datacontext with the object i have created. But I cant see any result, it always shows a blank listbox. Can someone tell me if see why is happening ? Code of c# VDt = new ObservableCollection<GClass>(); var vhDt = message.SelectSingleElement(typeof (Vh)) as Vehiculo; if(vhDt != null) { VDt.Add(new GClass() {Name = "Numero: ", Value = ""}); VDt.Add(new GClass() {Name = "Marca: ", Value = ""}); VDt.Add(new GClass() {Name = "Conductor: ", Value = ""}); lstview.DataContext = this; _regionManager.RegisterViewWithRegionInIndex(RegionNames.MainRegion, lstview, 0); Code of the view <ListBox Margin="5,5,5,25" ItemsSource="{Binding VDt}"> <ListBox.Template> <ControlTemplate> <ListViewItem Content="{Binding Name}"></ListViewItem> <ListViewItem Content="{Binding Value}"></ListViewItem> </ControlTemplate> </ListBox.Template> </ListBox> I have research here, but i cant see, what I'm doing wrong. I will apreciate if someone help me.

  • asp.net mvc cookies not being sent back

    - by brian b
    My application at mysubdomain.mydomain.com needs to set a cookie that contains some user session information. They log in at a https page. We authenticate them and set some session info in a cookie. We do this in a helper library that takes in the controller context contextBase.Response.Cookies[CookiePayload.CookieName].Value = encryptedTicket; contextBase.Response.Cookies[CookiePayload.CookieName].Expires = cookieExpires; contextBase.Response.Cookies[CookiePayload.CookieName].Domain= ConfigHelper.CookieDomain; contextBase.Response.Cookies[CookiePayload.CookieName].HttpOnly=true; We do a quick redirect in the controller (to a non https page): this.ControllerContext.HttpContext.Response.Redirect(redirectTo, false); return null; The cookie appears in the response (according to firebug's net tab). But neither fireforx nor ie send the cookie on subsequent gets. We are setting the cookie domain to mydomain.com even though the site is mysubdomain.mydomain.com. Skipping the redirect command has no effect, nor does changing the cookie value. I'm baffled. Thanks for any suggestions.

  • Jackson object mapping - map incoming JSON field to protected property in base class

    - by Pete
    We use Jersey/Jackson for our REST application. Incoming JSON strings get mapped to the @Entity objects in the backend by Jackson to be persisted. The problem arises from the base class that we use for all entities. It has a protected id property, which we want to exchange via REST as well so that when we send an object that has dependencies, hibernate will automatically fetch these dependencies by their ids. Howevery, Jackson does not access the setter, even if we override it in the subclass to be public. We also tried using @JsonSetter but to no avail. Probably Jackson just looks at the base class and sees ID is not accessible so it skips setting it... @MappedSuperclass public abstract class AbstractPersistable<PK extends Serializable> implements Persistable<PK> { @Id @GeneratedValue(strategy = GenerationType.AUTO) private PK id; public PK getId() { return id; } protected void setId(final PK id) { this.id = id; } Subclasses: public class A extends AbstractPersistable<Long> { private String name; } public class B extends AbstractPersistable<Long> { private A a; private int value; // getter, setter // make base class setter accessible @Override @JsonSetter("id") public void setId(Long id) { super.setId(id); } } Now if there are some As in our database and we want to create a new B via the REST resource: @POST @Consumes(MediaType.APPLICATION_JSON) @Produces(MediaType.APPLICATION_JSON) @Transactional public Response create(B b) { if (b.getA().getId() == null) cry(); } with a JSON String like this {"a":{"id":"1","name":"foo"},"value":"123"}. The incoming B will have the A reference but without an ID. Is there any way to tell Jackson to either ignore the base class setter or tell it to use the subclass setter instead? I've just found out about @JsonTypeInfo but I'm not sure this is what I need or how to use it. Thanks for any help!

  • Aggregate survey results recursively by manager

    - by Ian Roke
    I have a StaffLookup table which looks like this. UserSrn | UserName | ManagerSrn =============================== ABC1 | Jerome | NULL ABC2 | Joe | ABC1 ABC3 | Paul | ABC2 ABC4 | Jack | ABC3 ABC5 | Daniel | ABC3 ABC6 | David | ABC2 ABC7 | Ian | ABC6 ABC8 | Helen | ABC6 The staff structure looks like this. |- Jerome | |- Joe || ||- Paul ||| |||- Jack ||| |||- Daniel || ||- David ||| |||- Ian ||| |||- Helen I have a list of SurveyResponses that looks like this. UserSrn | QuestionId | ResponseScore ==================================== ABC2 | 1 | 5 ABC2 | 3 | 4 ABC4 | 16 | 3 ... What I am trying to do sounds pretty simple but I am struggling to find a neat, quick way of doing it. I want to create a sproc that takes an Srn and returns back all the staff under that Srn in the structure. If there is a score for QuestionId of 16 then that indicates a completed survey. I would like to return a line for the Srn entered (The top manager) with a count of completed surveys for the direct reports under that manager. Under that I would like each manager under the original manager with a count of completed surveys for each of their direct reports and so on. I would like to see the data as such below when I set the top manager to be Joe (ABC2). UserName | Completed | Total ============================ Joe | 2 | 2 Paul | 1 | 2 David | 0 | 2 TOTAL | 3 | 6

  • Android fragments problems different layouts

    - by juan
    I have two layouts: one for portait with one container and another for landscape with two containers. In the first layout I show a fragment and when the user select one element, I replace the fragment with another (with FragmentTransation.Replace). <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" > <LinearLayout android:id="@+id/container1" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" /> </RelativeLayout> In the second layout I want to show the two fragments at one time, one in the first container and the second in the second container. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal" > <LinearLayout android:id="@+id/container1" android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="3" android:orientation="vertical" /> <LinearLayout android:id="@+id/container2" android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="7" android:orientation="vertical" /> </LinearLayout> But I can't make this works with configuration changes. I try use different names for containers, try add fragments when only bundle is null,... Someone have a working code of this case?

  • Dynamically add event to custom control (Confirm Message Box)

    - by Nyein Nyein Chan Chan
    I have created a custom cofirm message box control and I created an event like this- [Category("Action")] [Description("Raised when the user clicks the button(ok)")] public event EventHandler Submit; protected virtual void OnSubmit(EventArgs e) { if (Submit != null) Submit(this, e); } The Event OnSubmit occurs when user click the OK button on the Confrim Box. void IPostBackEventHandler.RaisePostBackEvent(string eventArgument) { OnSubmit(e); } Now I am adding this OnSubmit Event Dynamically like this- In aspx- <my:ConfirmMessageBox ID="cfmTest" runat="server" ></my:ConfirmMessageBox> <asp:Button ID="btnCallMsg" runat="server" onclick="btnCallMsg_Click" /> <asp:TextBox ID="txtResult" runat="server" ></asp:TextBox> In cs- protected void btnCallMsg_Click(object sender, EventArgs e) { cfmTest.Submit += cfmTest_Submit;//Dynamically Add Event cfmTest.ShowConfirm("Are you sure to Save Data?"); //Show Confirm Message using Custom Control Message Box } protected void cfmTest_Submit(object sender, EventArgs e) { txtResult.Text = "User Confirmed";//I set the text to "User Confrimed" but it's not displayed txtResult.Focus();//I focus the textbox but I got Error } The Error I got is- System.InvalidOperationException was unhandled by user code Message="SetFocus can only be called before and during PreRender."

Can anybody help me to add event dynamically to custom control? Thanks.

  • Difference dynamic static 2d array c++

    - by snorlaks
    Hello, Im using opensource library called wxFreeChart to draw some XY charts. In example there is code which uses static array as a serie : double data1[][2] = { { 10, 20, }, { 13, 16, }, { 7, 30, }, { 15, 34, }, { 25, 4, }, }; dataset->AddSerie((double *) data1, WXSIZEOF(dynamicArray)); WXSIZEOF ismacro defined like: sizeof(array)/sizeof(array[0]) In this case everything works great but in my program Im using dynamic arrays (according to users input). I made a test and wrotecode like below: double **dynamicArray = NULL; dynamicArray = new double *[5] ; for( int i = 0 ; i < 5 ; i++ ) dynamicArray[i] = new double[2]; dynamicArray [0][0] = 10; dynamicArray [0][1] = 20; dynamicArray [1][0] = 13; dynamicArray [1][1] = 16; dynamicArray [2][0] = 7; dynamicArray [2][1] = 30; dynamicArray [3][0] = 15; dynamicArray [3][1] = 34; dynamicArray [4][0] = 25; dynamicArray [4][1] = 4; dataset->AddSerie((double *) *dynamicArray, WXSIZEOF(dynamicArray)); But it doesnt work correctly. I mean point arent drawn. I wonder if there is any possibility that I can "cheat" that method and give it dynamic array in way it understands it and will read data from correct place thanks for help

  • Linq - Orderby not ordering

    - by Billy Logan
    Hello everyone, I have a linq query that for whatever reason is not coming back ordered as i would expect it to. Can anyone point me in the right direction as to why and what i am doing wrong? Code is as follows: List<TBLDESIGNER> designer = null; using (SOAE strikeOffContext = new SOAE()) { //Invoke the query designer = AdminDelegates.selectDesignerDesigns.Invoke(strikeOffContext).ByActive(active).ByAdmin(admin).ToList(); } Delegate: public static Func<SOAE, IQueryable<TBLDESIGNER>> selectDesignerDesigns = CompiledQuery.Compile<SOAE, IQueryable<TBLDESIGNER>>( (designer) => from c in designer.TBLDESIGNER.Include("TBLDESIGN") orderby c.FIRST_NAME ascending select c); Filter ByActive: public static IQueryable<TBLDESIGNER> ByActive(this IQueryable<TBLDESIGNER> qry, bool active) { //Return the filtered IQueryable object return from c in qry where c.ACTIVE == active select c; } Filter ByAdmin: public static IQueryable<TBLDESIGNER> ByAdmin(this IQueryable<TBLDESIGNER> qry, bool admin) { //Return the filtered IQueryable object return from c in qry where c.SITE_ADMIN == admin select c; } Wondering if the filtering has anything to do with it?? Thanks in advance, Billy
