  • How to avoid circular relationship in SQL-Server?

    - by Shimmy
    I am creating a self-related table: Table Item columns: ItemId int - PK; Amount money - not null; Price money - a computed column using a UDF that retrieves value according to the items ancestors' Amount. ParentItemId int - nullable, reference to another ItemId in this table. I need to avoid a loop, meaning, a sibling cannot become an ancestor of his ancestors, meaning, if ItemId=2 ParentItemId = 1, then ItemId 1 ParentItemId = 2 shouldn't be allowed. I don't know what should be the best practice in this situation. I think I should add a CK that gets a Scalar value from a UDF or whatever else. EDIT: Another option is to create an INSTEAD OF trigger and put in 1 transaction the update of the ParentItemId field and selecting the Price field from the @@RowIdentity, if it fails cancel transaction, but I would prefer a UDF validating. Any ideas are sincerely welcomed.

  • Can't get NSTableView to display data.

    - by Alberto
    Hi! I see there are a lot of questions about this, but nothing helped me to get this work. I have a nib with a NSTableView with three columns (with the right identifiers set) and a class named ShortcutsTableController. In the nib I have a NSObject with class value ShortcutsTableController. I also connected the NSTableView to my controller as I usually do. This is header ShortcutsTableController.h. #import <Cocoa/Cocoa.h> @interface ShortcutsTableController : NSObject <NSTableViewDataSource> { IBOutlet NSTableView *shortcutsTable; NSMutableArray *shortcutsList; } - (int) numberOfRowsInTableView: (NSTableView*) tableView; - (id)tableView:(NSTableView *)tableView objectValueForTableColumn:(NSTableColumn *)tableColumn row:(int)row; @property (assign) IBOutlet NSTableView *shortcutsTable; - (void)setUpTable; @end And this is the implementation file ShortcutsTableController.m. #import "ShortcutsTableController.h" @implementation ShortcutsTableController @synthesize shortcutsTable; - (void)setUpTable { shortcutsList = [[NSMutableArray alloc] init]; NSDictionary *dict1 = [NSDictionary dictionaryWithObjectsAndKeys: @"blabla", @"nameColumn", @"Bla bla bla", @"shortcutColumn", @"Ribla", @"actionColumn", nil]; [shortcutsList addObject:dict1]; [shortcutsTable setDataSource:self]; [shortcutsTable reloadData]; } -(int) numberOfRowsInTableView: (NSTableView *) tableView { return [shortcutsList count]; } - (id)tableView:(NSTableView *)tableView objectValueForTableColumn:(NSTableColumn *)tableColumn row:(int)row { if (row != -1) return [[shortcutsList objectAtIndex:row] objectForKey:[tableColumn identifier]]; return nil; } @end But when i try to build nothing appears in the NSTableView. No errors, no warnings. Note that I call setUpTable from within the Delegate Class Method awakeFromNib. Is there something I am doing wrong? Thank you for you help. —Albé UPDATE. Added lines @property (assign) IBOutlet NSTableView *shortcutsTable; in header and @synthesize shortcutsTable; in implementation. Nothing changes. :(

  • Styling hyperlink button inside a data template in Silverlight

    - by cmaduro
    How do I change the visual state of a hyperlinkbutton inside a datatemplate? In short, what I'm doing is basically I'm trying to iterate of the hyperlinkbuttons and set their visual state to active or inactive according to the url. The hyperlink buttons are located inside the datatemplate of an itemscontrols itemsource that is bound to a List where link is my custom class for links. Is there a best practice for styling the active hyperlink in a silverlight nav app? What I am using is the approach of the boilerplate code.

  • Using constructor to load data in subsonic3?

    - by Dennis
    I'm getting an error while trying to load an record through the constructor. The constructor is: public Document(Expression<Func<Document,bool>> expression); and i try to load a single item in like this var x = new Document(f=>f.publicationnumber=="xxx"); publicationnumber isn't a key but tried making an it an unique key and still no go.. Am i totally wrong regarding the use of the constructor? and can someone please tell me how to use that constructor? The error i'm getting is: Test method TestProject1.UnitTest1.ParseFileNameTwoProductSingleLanguage threw exception: System.NullReferenceException: with the following stacktrace: SubSonic.Query.SqlQuery.Where[T](Expression1` expression) Load`[T]`(T item, Expression1expression) db.Document..ctor(Expression``1 expression) in C:\@Projects\DocumentsSearchAndAdmin\DocumentsSearchAndAdmin\Generated\ActiveRecord.cs: line 5613 rest removed for simplicity Regards Dennis

  • Insert some data at later point once serialization(binary serialization) is done for a class

    - by coolcake
    My application is written in C# and I am a newbie to C#. I am facing with a problem during serialization. The problem is as follows. There are many classes in my project and when serialization is called on one of the main class object it serializes itself and during this process many of the member objects are also get serialized. This whole serialization is done in to a file with extension say ".bin". This bin file size should be of size max 20MB. In this process of serialization one of my other class also gets serialized to a stream, this class is having a big array. The size of this array or list can be of 80 MB or more. So during serialization i have serialize all the objects other than this array and depending upon the size left in the 20MB I need to add in between the serialization the number of array elements which can fit in the remaining memory. For the other array elements left out I have to create a similar kind of .bin file with all the objects serialized and in between need to insert the number of array elements that can fit there. The main problem here is the array elements get inserted at runtime and this list keeps on increasing. So i should be creating .bin files continuously until my application runs. Any ideas how can i implement a solution for this problem? Thanks in Advance.

  • JAX-WS MarshalException with custom JAX-B bindings: Unable to marshal type "java.lang.String" as an

    - by MoneyMark
    I seem to be having an issue with Jax-WS and Jax-b playing nicely together. I need to consume a web-service, which has a predefined WSDL. When executing the generated client I am receiving the following error: javax.xml.ws.WebServiceException: javax.xml.bind.MarshalException - with linked exception: [com.sun.istack.SAXException2: unable to marshal type "java.lang.String" as an element because it is missing an @XmlRootElement annotation] This started occurring when I used an external custom binding file to map needlessly complex types to java.lang.string. Here is an excerpt from my binding file: <?xml version="1.0" encoding="UTF-8"?> <bindings xmlns="http://java.sun.com/xml/ns/jaxb" version="2.0" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"> <bindings schemaLocation="http://localhost:7777/GESOR/services/RegistryUpdatePort?wsdl#types?schema1" node="/xs:schema"> <bindings node="//xs:element[@name='StwrdCompany']//xs:complexType//xs:sequence//xs:element[@name='company_name']"> <property> <baseType name="java.lang.String" /> </property> </bindings> <bindings node="//xs:element[@name='StwrdCompany']//xs:complexType//xs:sequence//xs:element[@name='address1']"> <property> <baseType name="java.lang.String" /> </property> </bindings> <bindings node="//xs:element[@name='StwrdCompany']//xs:complexType//xs:sequence//xs:element[@name='address2']"> <property> <baseType name="java.lang.String" /> </property> </bindings> ...more fields </bindings> </bindings> When executing wsimport against the provided WSDL, StwrdCompany is generated with the following variables declared: @XmlRootElement(name = "StwrdCompany") public class StwrdCompany { @XmlElementRef(name = "company_name", type = JAXBElement.class) protected String companyName; @XmlElementRef(name = "address1", type = JAXBElement.class) protected String address1; @XmlElementRef(name = "address2", type = JAXBElement.class) ... more fields ... getters/setters @XmlAccessorType(XmlAccessType.FIELD) @XmlType(name = "", propOrder = { "value" }) public static class CompanyName { @XmlValue protected String value; @XmlAttribute protected Boolean updateToNULL; /** * Gets the value of the value property. * * @return * possible object is * {@link String } * */ public String getValue() { return value; } /** * Sets the value of the value property. * * @param value * allowed object is * {@link String } * */ public void setValue(String value) { this.value = value; } /** * Gets the value of the updateToNULL property. * * @return * possible object is * {@link Boolean } * */ public boolean isUpdateToNULL() { if (updateToNULL == null) { return false; } else { return updateToNULL; } } /** * Sets the value of the updateToNULL property. * * @param value * allowed object is * {@link Boolean } * */ public void setUpdateToNULL(Boolean value) { this.updateToNULL = value; } ... more inner classes } } Finally, here is the associated snippet from the WSDL that seems to be causing such grief. <xs:element name="StwrdCompany"> <xs:complexType> <xs:sequence> <xs:element maxOccurs="1" minOccurs="0" name="company_name" nillable="true"> <xs:complexType> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute default="false" name="updateToNULL" type="xs:boolean"/> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:element> <xs:element maxOccurs="1" minOccurs="0" name="address1" nillable="true"> <xs:complexType> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute default="false" name="updateToNULL" type="xs:boolean"/> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:element> ... more fields in the same format <xs:element maxOccurs="1" minOccurs="0" name="p_source_timestamp" nillable="false" type="xs:string"/> </xs:sequence> <xs:attribute name="company_xid" type="xs:string"/> </xs:complexType> </xs:element> The reason for the custom binding is so I can map user input from a pojo into the StwrdCompany object more easily, whether it be direct instantiation or through the use of Dozer for bean mapping. I was unable to successfully map between the objects without the custom binding. Finally, one other thing I tried was setting a globalBinding definition: <globalBindings generateValueClass="false"></globalBindings> This caused the server to through an argument mismatch exception since the Soap Message was using xs:string xml types instead of passing the defined complex types, so I abandoned that idea. Any insight into what is causing the MarshalException or how to go about solving the issue of calling the webservice and mapping these objects more easily, is greatly appreciated. I've been searching for days and I sadly think I am stumped.

  • Finding duplicate rows in SQL Server

    - by xtine
    I have a SQL Server database of organizations, and there are many duplicate rows. I want to run a select statement to grab all of these and the amount of dupes, but also return the ids that are associated with each organization. A statement like: SELECT orgName, COUNT(*) AS dupes FROM organizations GROUP BY orgName HAVING (COUNT(*) > 1) Will return something like orgName | dupes ABC Corp | 7 Foo Federation | 5 Widget Company | 2 But I'd also like to grab the IDs of them. Is there any way to do this? Maybe like a orgName | dupeCount | id ABC Corp | 1 | 34 ABC Corp | 2 | 5 ... Widget Company | 1 | 10 Widget Company | 2 | 2 The reason being that there is also a separate table of users that link to these organizations, and I would like to unify them (therefore remove dupes so the users link to the same organization instead of dupe orgs). But I would like part manually so I don't screw anything up, but I would still need a statement returning the IDs of all the dupe orgs so I can go through the list of users. Any help would be greatly appreciated. Thanks :)

  • Asp.NET MVC ActionFilter cannot get Form Submit data

    - by Goden
    I want to use custom action filter to manipulate parameters to one action. User inputs: 2 names in a form ; Action: actually needs to take 2 ids; Action Filter (onExecuting, will verify the input names and if valid, convert them into 2 ids and replace in the routedata) because i don't want to put validation logic in Action Controller. here's part of the code: Routing Info routes.MapRoute( "Default", // Route name "{controller}/{action}", // URL with parameters new { controller = "Home", action = "Index"} // Parameter defaults ); routes.MapRoute( "RelationshipResults", // Route Name "Relationship/{initPersonID}/{targetPersonID}", // URL with parameters new { controller = "Relationship", action = "Results" }); Form to submit (Create 2 input box and submit via jquery) <% using (Html.BeginForm("Results", "Relationship", FormMethod.Post, new { id = "formSearch" })) {% ... <td align="left"><%: MvcWeibookWeb.Properties.Resource.Home_InitPersonName%></td> <td align="right"> <%= Html.TextBox("initPersonName")%></td> <td rowspan="3" valign="top"> <div id="sinaIntro"> <%: MvcWeibookWeb.Properties.Resource.Home_SinaIntro %> <br /> <%: MvcWeibookWeb.Properties.Resource.Genearl_PromotionSina %> </div> </td> </tr> <tr> <td align="left" width="90px"><%: MvcWeibookWeb.Properties.Resource.Home_TargetPersonName%></td> <td align="right"><%= Html.TextBox("targetPersonName")%></td> </tr> <tr> <td colspan="2" align="right"> <a href="#" class="btn-HomeSearch" onclick="$('#formSearch').submit();"><%: MvcWeibookWeb.Properties.Resource.Home_Search%></a> </td> Action Filter public override void OnActionExecuting(ActionExecutingContext filterContext) { Sina.Searcher searcher = new Sina.Searcher(Sina.Processor.UserNetwork); String initPersonName, targetPersonName; // form submit names, we need to process them and convert them to IDs before it enters the real controller. initPersonName = filterContext.RouteData.Values["initPersonName"] as String; targetPersonName = filterContext.RouteData.Values["targetPersonName"] as String; // do sth to convert it to ids and replace Action/Controller [ValidationActionFilter] [HandleError] public ActionResult Results( Int64 initPersonName, Int64 targetPersonName) { ... My problem is: in the actionFilter, it never gets the 2 parameter "initPersonName" and "targetPersonName", the RouteData.Values don't contain these 2 keys... :(

  • WPF - Dynamic tooltip

    - by Al Mackenzie
    I have a class ToolTipProvider which has a method string GetToolTip(UIElement element) which will return a specific tooltip for the UIElement specified, based on various factors including properties of the UIElement itself and also looking up into documentation which can be changed dynamically. It will also probably run in a thread so when the form first fires up the tooltips will be something like the visual studio 'Document cache is still being constructed', then populated in the background. I want to allow this to be used in any wpf form with the minimum effort for the developer. Essentially I want to insert an ObjectDataProvider resource into the Window.Resources to wrap my ToolTipProvider object, then I think I need to create a tooltip (called e.g. MyToolTipProvider) in the resources which references that ObjectDataProvider, then on any element which requires this tooltip functionality it would just be a case of ToolTip="{StaticResource MyToolTipProvider}" however I can't work out a) how to bind the actual elemnt itself to the MethodParameters of the objectdataprovider, or b) how to force it to call the method each time the tooltip is opened. Any ideas/pointers on the general pattern I need? Not looking for complete solution, just any ideas from those more experienced

See schema for details: For getting all instance of EntityA which depend from EntityB.name I use the predicate like this: NSPredicate *predicate = [NSPredicate predicateWithFormat:@"ANY EntityB.name like 'SomeName'"]; What should be predicate for getting all instance of EntityA which depend from EntityC.name? I tried query like @"ANY EntityB.entitiesC.name like 'SomeName'" but get exception "multiple to-many keys not allowed here". Best regards, Victor

  • One to many too much data returned - MySQL

    - by Evan McPeters
    I have 2 related MySQL tables in a one to many relationship. Customers: cust_id, cust_name, cust_notes Orders: order_id, cust_id, order_comments So, if I do a standard join to get all customers and their orders via PHP, I return something like: Jack Black, jack's notes, comments about jack's 1st order Jack Black, jack's notes, comments about jack's 2nd order Simon Smith, simon's notes, comments about simon's 1st order Simon Smith, simon's notes, comments about simon's 2nd order The problem is that *cust_notes* is a text field and can be quite large (a couple of thousand words). So, it seems like returning that field for every order is inneficient. I could use *GROUP_CONCAT* and JOINS to return all *order_comments* on a single row BUT order_comments is a large text field too, so it seems like that could create a problem. Should I just use two separate queries, one for the customers table and one for the orders table? Is there a better way?

  • How can I extract similarities/patterns from a collection of binary strings?

    - by JohnIdol
    I have a collection of binary strings of given size encoding effective solutions to a given problem. By looking at them, I can spot obvious similarities and intuitively see patterns of symmetry and periodicity. Are there mathematical/algorithmic tools I can "feed" this set of strings to and get results that might give me an idea of what this set of strings have in common? By doing so I would be able to impose a structure (or at least favor some features over others) on candidate solutions in order to greatly reduce the search space, maximizing chances to find optimal solutions for my problem (I am using genetic algorithms as the search tool - but this is not pivotal to the question). Any pointers/approaches appreciated.

  • VSTO outlook data issue through exchange sync

    I wrote an addin for outlook, It will popup appointment's LastModificationTime while I click button the button eventhandler like this Outlook.ApplicationClass outlook = new Outlook.ApplicationClass(); Outlook.NameSpace ns = outlook.GetNamespace("MAPI"); Outlook.MAPIFolder folder = ns.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderCalendar); Outlook.Items FolderItems = folder.Items; DateTime MyDate = DateTime.Now; List<Outlook.AppointmentItem> Appts = ( from Outlook.AppointmentItem i in folder.Items where i.Start.Month == MyDate.Month && i.Start.Year == MyDate.Year select i).ToList(); foreach (Outlook.AppointmentItem Appt in Appts) { System.Windows.Forms.MessageBox.Show(Appt.LastModificationTime.ToString()); } the issue is happened while I changed appointment in my mobile phone, then sync it to the outlook through exchange server steps which makes issue: click button, get LastModificationTime as "time1" change start date as "start1" in my mobile phone, sync to outlook through exchange server click button, get LastModificationTime, still "time1" change start date as "start2" in outlook, but the appointment is still in "start1" date. restart outlook click button, get new LastModificationTime as "time2", and appointment is in "start1" date, "start2" is gone. steps without issue click button, get LastModificationTime as "time1" 1.1. restart outlook change start date as "start1" in my mobile phone, sync to outlook through exchange server click button, get LastModificationTime, "time2" It looks like List Appts is never been refreshed to latest value if the appointment is changed through exchange server. Is there any solution for this issue? or other reason to make it happened?

  • Odd Infragistics UltraComboEditor data binding non-bug

    - by Richard Dunlap
    Within an Infragistics 8.2 UltraComboEditor, we had the following properties set via C#: DataSource = dataSource; ValueMember = "Measure"; DisplayMember = "Name"; DataBindings.Add("Value", repository, "Measure"); DataBindings["Value"].DataSourceUpdateMode = DataSourceUpdateMode.OnPropertyChanged; where dataSource was an array of objects, each with a property Measure, and repository was an object with a property Measure. (Those strings are actually constructor parameters -- just using explicit strings to simplify the example.) In the course of some refactoring, the name of the property on the objects in the array was changed to BaseEnum (the objects are actually wrapped enumerations, for the curious), but the name of ValueMember above was not changed. And yet, the combo box binding continued to work through initial testing, beta testing, and even after release... until two customers emailed in noting that the combo box was no longer changing the underlying parameter. We were able to dig out the problem by careful study of the source code repository... despite being in the awkward position of not being able to replicate the buggy behavior internally. Two part question: What's happening under the hood that allowed the binding to continue to function, and/or what might be unique about those two users that caused the binding to (correctly) fail? (O/S version isn't alone the answer, and we get the unexpectedly functioning binding on machines that have never had a version of the software before, so we're not looking at rogue binaries). Are there tools that might have been able to warn us about the misbind, even if something was cleaning up behind?

  • Return extra data besides tree data from ExtJS TreeLoader dataUrl?

    - by Chad Johnson
    I asked this question in the Ext JS forums, but I received no responses, so I am asking here. I have a TreePanel (code below) that uses a TreeLoader and an AsyncTreeNode. In my API method specified by the TreeLoader's dataUrl, I return a JSON array to populate the tree. This works great, of course. However, I need to return an additional item--an integer--in addition to the array, and I need to display that value somewhere else in my UI. Is this possible? If not, what else would be a good solution? Here's the code I have currently: tree = new Ext.tree.TreePanel({ enableDD: true, rootVisible: false, useArrows: true, loader: new Ext.tree.TreeLoader({ dataUrl: '/api/method' }), root: new Ext.tree.AsyncTreeNode() });
