  • Where is my SQLite database?

    - by Brian Ramsay
    I have installed SQLite version 3 into a non-standard location on my dreamhost user account. I compiled it and installed it just fine, and it works with $db=new SQLiteDatabase("db.foont"); I can create tables and insert and read data with the SQLiteDatabase object just fine. However, I want to use PDO. My problem is that PDO requires an absolute path to the database specified in the connection. e.g., 'sqlite:/path/to/db.sq3' a) this is dumb - if the other object can figure out where the db is without an absolute path why can't PDO's sqlite driver - but that's not my question. b) where the heck is my database being stored? I can't find it anywhere in my user filesystem, and I'm pretty sure I don't have access to anything else.

  • Adding existing entity to navigation property of a different entity

    - by Shay Friedman
    I'm using EF4 and I'm running into a problem when I try to do something that looks quite trivial to me. I have two entities, let's call them A and B. These entities have a many-to-many association between them with a navigation property on A that contains a list of related B entities. What I want to do is to add existing B entities to a new A entity. When I try to do that, I get an exception: AcceptChanges cannot continue because the object's key values conflict with another object in the ObjectStateManager. Make sure that the key values are unique before calling AcceptChanges. Has anyone run into such a problem?

  • NHibernate CreateSQLQuery data conversion from bit to boolean error

    - by RemotecUk
    Hi, Im being a bit lazy in NHibernate and using Session.CreateSqlQuery(...) instead of doing the whole thing with Lambda's. Anyway what struct me is that there seems to be a problem converting some of the types returned from (in this case the MySQL) DB into native .Net tyes. The query in question looks like this.... IList<Client> allocatableClients = Session.CreateSQLQuery( "select clients.id as Id, clients.name as Name, clients.customercode as CustomerCode, clients.superclient as SuperClient, clients.clienttypeid as ClientType " + ... ... .SetResultTransformer(new NHibernate.Transform.AliasToBeanResultTransformer(typeof(Client))).List<Client>(); The type in the database of SuperClient is a bit(1) and in the Client object the type is a bool. The error received is: System.ArgumentException: Object of type 'System.UInt64' cannot be converted to type 'System.Boolean'. It seems strange that this conversion cannot be completed. Would be greatful for any ideas. Thanks.

  • Linq guru - filtering related entities...

    - by vdh_ant
    My table structure is as follows: Person 1-M PesonAddress Person 1-M PesonPhone Person 1-M PesonEmail Person 1-M Contract Contract M-M Program Contract M-1 Organization At the end of this query I need a populated object graph where each person has their: PesonAddress's PesonPhone's PesonEmail's PesonPhone's Contract's - and this has its respective Program's Now I had the following query and I thought that it was working great, but it has a couple of problems: from people in ctx.People.Include("PersonAddress") .Include("PersonLandline") .Include("PersonMobile") .Include("PersonEmail") .Include("Contract") .Include("Contract.Program") where people.Contract.Any( contract => (param.OrganizationId == contract.OrganizationId) && contract.Program.Any( contractProgram => (param.ProgramId == contractProgram.ProgramId))) select people; The problem is that it filters the person to the criteria but not the Contracts or the Contract's Programs. It brings back all Contracts that each person has not just the ones that have an OrganizationId of x and the same goes for each of those Contract's Programs respectively. What I want is only the people that have at least one contract with an OrgId of x with and where that contract has a Program with the Id of y... and for the object graph that is returned to have only the contracts that match and programs within that contract that match. I kinda understand why its not working, but I don't know how to change it so it is working... This is my attempt thus far: from people in ctx.People.Include("PersonAddress") .Include("PersonLandline") .Include("PersonMobile") .Include("PersonEmail") .Include("Contract") .Include("Contract.Program") let currentContracts = from contract in people.Contract where (param.OrganizationId == contract.OrganizationId) select contract let currentContractPrograms = from contractProgram in currentContracts let temp = from x in contractProgram.Program where (param.ProgramId == contractProgram.ProgramId) select x where temp.Any() select temp where currentContracts.Any() && currentContractPrograms.Any() select new Person { PersonId = people.PersonId, FirstName = people.FirstName, ..., ...., MiddleName = people.MiddleName, Surname = people.Surname, ..., ...., Gender = people.Gender, DateOfBirth = people.DateOfBirth, ..., ...., Contract = currentContracts, ... }; //This doesn't work But this has several problems (where the Person type is an EF object): I am left to do the mapping by myself, which in this case there is quite a lot to map When ever I try to map a list to a property (i.e. Scholarship = currentScholarships) it says I can't because IEnumerable is trying to be cast to EntityCollection Include doesn't work Hence how do I get this to work. Keeping in mind that I am trying to do this as a compiled query so I think that means anonymous types are out.

  • When creating a new IIS web site, how can I add it to an existing application pool?

    - by Ian Robinson
    I have successfully automated the process of creating a new IIS website, however the code I've written doesn't care about application pools, it just gets added to DefaultAppPool. However I'd like to add this newly created site to an existing application pool. Here is the code I'm using to create the new website. var w3Svc = new DirectoryEntry(string.Format("IIS://{0}/w3svc", webserver)); var newsite = new object[] { serverComment, new object[] { serverBindings }, homeDirectory }; var websiteId = w3Svc.Invoke("CreateNewSite", newsite); site.Invoke("Start", null); site.CommitChanges(); <update Although this is not directly related to the question, here are some sample values being used above. This might help someone understand exactly what the code above is doing more easily. webServer: "localhost" serverComment: "testing.dev" serverBindings: ":80:testing.dev" homeDirectory: "c:\inetpub\wwwroot\testing\" </update If I know the name of the application pool that I'd like this web site to be in, how can I find it and add this site to it?

  • In LINQ-SQL, wrap the DataContext is an using statement - pros cons

    - by hIpPy
    Can someone pitch in their opinion about pros/cons between wrapping the DataContext in an using statement or not in LINQ-SQL in terms of factors as performance, memory usage, ease of coding, right thing to do etc. Update: In one particular application, I experienced that, without wrapping the DataContext in using block, the amount of memory usage kept on increasing as the live objects were not released for GC. As in, in below example, if I hold the reference to List of q object and access entities of q, I create an object graph that is not released for GC. DataContext with using using (DBDataContext db = new DBDataContext()) { var q = from x in db.Tables where x.Id == someId select x; return q.toList(); } DataContext without using and kept alive DBDataContext db = new DBDataContext() var q = from x in db.Tables where x.Id == someId select x; return q.toList(); Thanks.

  • TextView defined in main.xml - how to "name" it to be able to use - setText() method?

    - by Oliver Goossens
    Hi, I am exploring android and developement and I found one problem. My app UI is defined in main.xml I have 2 texts and 2 buttons defined - easy app. I read that I may be able to change TEXT in the ACTIVITY using the setText() method. And thats the problem - how do I POINT the setText() Method? How do I tell it to change a specified text? If I would declare the TextView inside the Activity with NEW TextView NAME Object, I would just need to use NAME.setText(STRING)... But I didnt so i dont have anything like NAME of the object? How can this be done? I read something about r.IDs but I truly dont have a idea how to use them, where to find them and how to implement it .... Please advise Thank you Oliver

  • IDataServiceMetadataProvider / ResourceType.... what for dynamic types with no CLR type?

    - by TomTom
    Hello, I try to expose a database via ADO RIA for which we have only an ODBC based interface. The "database" is a server and new elements are developped all the time, so I would like the server to check metadata at start (using the odbc schema methods) and then expose what he finds via RIA services.... clients can the nregenerate when they need access to new elements. As such, I dont ahve any CLR types for all the tabled developped. ResourceType tableType = new ResourceType( typeof(object), ResourceTypeKind.EntityType, null, "Martini", table_name, false ); tableType.CanReflectOnInstanceType = false; I can somehow not put in NULl as CLR element type, and entering typeof(object) seems to result in reflection errors when trying to access the properties. Any documentation on how to do that? I dont really want to get into having types... though if I have to, I probably will dynamically generate some via bytecode emit.

    I define two XML type (base and derived types). <xs:complexType name="ParentType"> ... </xs:complexType> <xs:complexType name="ChildType"> <xs:complexContent> <xs:extension base="ParentType"> ... </xs:complexContent> </xs:complexType> Now, I have an XML instance of ChildType. The question, If I once unmarshall the XML into ParentType java object, can I downcast the java object to its subclass of ChildType? Is that possible to that? thanks

  • Basic XStream Annotations

    - by jmcmahon
    Hello, I just started using XStream Annotations, and I am trying to figure out how to associate the annotations with the XStream object. From the documentation, it seems like this is the accepted method: XStream xstream = new XStream(new DomDriver()); xstream.processAnnotations(AnnotatedClass.class); My problem with this is that Eclipse isn't recognizing this as a valid method. Everything seems to be configured correctly in Eclipse because it shows me the rest of the methods that are in the XStream object. It's almost like Eclipse thinks it's an older version of xstream. I've tried running a Project Clean inside of Eclipse but that didn't fix anything. I've also tried downloading the XStream jar again which didn't help either. Versions: XStream 1.3.1, Eclipse 3.4, Java 6 Has anybody seen this strange behavior before, or have any ideas on how to fix it?

  • Stringtemplate: is it ok to Apply Templates, in which HashMap uses, To Multi-Valued Attributes

    - by user1071830
    There is two template in my .stg file, and both of them apply on multi-value a HashMap. The HashMap is employed as an injected object. And I need those instance of HashMap can be injected for many times. My trouble is, when I switch to another template, ANTLR seems to consider the second HashMap as a List -- multipul objects and null value. Part of my .stg file shows as follows: tpl_hash(BAR, FOO) ::= << <FOO:foo(); separator="\n"> <BAR:bar(); separator="\n"> >> foo(nn) ::= << foo: <nn.name; null="NULL"> . <nn.national; null="NULL"> >> bar(mm) ::= << bar: <mm.name> @ <mm.national> >> Part of my .g file shows: HashMap hm = new HashMap(); hm.put("name", $name.text); hm.put("national", "German"); tpl_hash.add("FOO",new HashMap(hm)); HashMap hm2 = new HashMap(); hm2.put("name", $name.text); hm2.put("national", "German"); tpl_hash.add("BAR",new HashMap(hm2)); The result I expect is : bar: Kant @ German foo: Russell @ England But, I got: foo: NULL . NULL foo: NULL . NULL bar: @ bar: @ If we replace BAR with FOO, as is, keeping FOO and BAR with identical template, the output is right, like the following. bar: Russell @ German bar: Russell @ German In docs, "synchronized ST add (String name, Object value) in org.stringtemplate.v4.ST" said: "If you send in a List and then inject a single value element, add() copies original list and adds the new value." What about a HashMap? Does ANTLR consider the HashMap, key/value pair access, an object purposely, as a List and as multi-value injected by mistake? Thanks a lot in advance.

  • Change Sprite Anchorpoint without moving it?

    - by Oscar Gomez
    I am trying to change my Sprite anchor point so that I can rotate over a 0.0f,0.0f anchorpoint. At first my object is rotation at the default anchor point (0.5f,0.5f). However later on I need it to rotate over a 0.0,0.0 AnchorPoint. The problem is I cannot change the anchor point and change the position accordingly, so it stays on the same position, without the object appearing to quickly move and reposition to its original point. Is there a way I can set the anchor point and the position of my Sprite at once, without it moving at all?. Thank you. -Oscar

  • C# - setting a property by reflection with a string value

    - by David Hodgson
    Hi, I'd like to set a property of an object through reflection, with a value of type string. So, for instance, suppose I have a Ship class, with a property of Latitude, which is a double. Here's what I'd like to do: Ship ship = new Ship(); string value = "5.5"; PropertyInfo propertyInfo = ship.GetType().GetProperty("Latitude"); propertyInfo.SetValue(ship, value, null); As is, this throws an Argument exception (Object of type 'System.String' cannot be converted to type 'System.Double'). How can I convert value to the proper type, based on propertyInfo?

  • LINQ to SQL: To Attach or Not To Attach

    - by bradhe
    So I'm have a really hard time figuring out when I should be attaching to an object and when I shouldn't be attaching to an object. First thing's first, here is a small diagram of my (very simplified) object model. Edit: Okay, apparently I'm not allowed to post images...here you go: http://i.imgur.com/2ROFI.png In my DAL I create a new DataContext every time I do a data-related operation. Say, for instance, I want to save a new user. In my business layer I create a new user. var user = new User(); user.FirstName = "Bob"; user.LastName = "Smith"; user.Username = "bob.smith"; user.Password = StringUtilities.EncodePassword("MyPassword123"); user.Organization = someOrganization; // Assume that someOrganization was loaded and it's data context has been garbage collected. Now I want to go save this user. var userRepository = new RepositoryFactory.GetRepository<UserRepository>(); userRepository.Save(user); Neato! Here is my save logic: public void Save(User user) { if (!DataContext.Users.Contains(user)) { user.Id = Guid.NewGuid(); user.CreatedDate = DateTime.Now; user.Disabled = false; //DataContext.Organizations.Attach(user.Organization); DataContext.Users.InsertOnSubmit(user); } else { DataContext.Users.Attach(user); } DataContext.SubmitChanges(); // Finished here as well. user.Detach(); } So, here we are. You'll notice that I comment out the bit where the DataContext attachs to the organization. If I attach to the organization I get the following exception: NotSupportedException: An attempt has been made to Attach or Add an entity that is not new, perhaps having been loaded from another DataContext. This is not supported. Hmm, that doesn't work. Let me try it without attaching (i.e. comment out that line about attaching to the organization). DuplicateKeyException: Cannot add an entity with a key that is already in use. WHAAAAT? I can only assume this is trying to insert a new organization which is obviously false. So, what's the deal guys? What should I do? What is the proper approach? It seems like L2S makes this quite a bit harder than it should be...

  • Dictionary is returning false on ContainsKey after item is added

    - by Karel Frajtak
    I have a dictionary declared as follows IDictionary<string, object> _objectIds = new Dictionary<string, object>(); I was experiencing some problems with it and it discovered that the instance returned false as a result of ContainsKey method and from the watch window I was sure that the item was there. So I created helper method private bool IdsContainsKey(string key) { lock (syncObject) { lock (_objectIds) { if (_objectIds.ContainsKey(key)) return true; // A if (_objectIds.ContainsKey(key)) return true; // B return _objectIds.ContainsKey(key); // C } } } During my debugging session I run into situation when the method exited in place B and sometimes I made to C returning true. Can anybody help me? Thanks.

  • Is this valid EJB-QL?

    - by Yishai
    I have the following construct in EJB-QL several EJB 2.1 finder methods: SELECT distinct OBJECT(rd) FROM RequestDetail rd, DetailResponse dr WHERE dr.updateReqResponseParentID is not null and dr.updateReqResponseParentID = ?1 and rd.requestDetailID = dr.requestDetailID and rd.deleted is null and dr.deleted is null IDEA's EJB-QL inspection flags the use of the two object FROM RequestDetail rd, DetailResponse dr with an inspection which says: Several ranged variable declarations are not supported, use collection member declarations instead (e.g. IN(o.lineItems)) The queries themselves function fine (as in return the expected results) on JBoss 4.2. Is IDEA all wet here, or is there a valid issue with the query? And what is the actual preferred alternative syntax for such a query?

  • How do I create interface methods using .tlb types in VS C++?

    - by Steven
    Background: The .TLB file contains interfaces written in language 'X'. I don't have .h, .idl, .tlh, or any other header files - just the .TLB file. Language 'X' does not export compatible .h, .idl, etc. I use the VS wizard to add an ATL simple object to my ATL project. I want to add a method to the interface of my simple ATL object that uses one of the .TLB defined types for a parameter. // Something like the following in the .idl file: interface ISomeInterface : IUnknown { HRESULT SomeMethod([in] ITypeFromTLB* aVal); // ITypeFromTLB declared in .TLB file. }; How can I do this? I'm hoping for a wizard, or a line in the .idl interface declaration that would bring in the .tlb information. midl's include (no .tlb), import (no tlb), and importlib (library only) don't seem to provide a solution (I need proxy/stub to be working, so I cannot put this inside the library declaration with the importlib command). Thanks.

  • When should you NOT use the asterisk (*) when declaring a variable in Objective C

    - by Jason
    I have just started learning objective c and the asterisk is giving me some trouble. As I look through sample code, sometime it is used when declaring a variable and sometimes it is not. What are the "rules" for when it should be used. I thought it had something to do with the data type of the variable. (asterisk needed for object data types, not needed for simple data types like int) However, I have seen object data types such as CGPoint declared without the asterisk as well? Is there a definitive answer or does it have to do with how and what you use the variable for?

  • Silverlight 4 accessing WCF Data Services: BeginInvoke frustrations.

    - by Gatmando
    Hi, I'm attempting to follow a pattern for performing WCF data service queries using the Silverlight 4 beta. The following is my code: public CodeTables() { CodeCountries = new ObservableCollection<dsRealHomes.CodeCountries>(); dsRealHomes.RealHomesEntities myClient = null; myClient = staticGlobals.RealHomesContext(); object userState = null; myClient.BeginExecute<dsRealHomes.CodeCountries>(new Uri("CodeCountries"), (IAsyncResult asyncResult) => { Dispatcher.BeginInvoke( () => { var test = myClient.EndExecute<dsRealHomes.CodeCountries>asyncResult).ToList(); } ); }, userState); } This is derived from a number of examples I've come across for WCF data services with silverlight. Unfortunately no matter how I try to implement the code i end up with the following error on 'Dispatcher.BeginInvoke': 'An object reference is required for the non-static field, method, or property (System.Windows.Threading.Dispatcher.BeginInvoke(System.Action)' Thanks

  • iPhone generalPasteboard loses contents if application is closed by an -openURL: call

    - by Kojiro
    I have a method, that puts something on the pasteboard. This method is called one of two ways, one, as an IBAction from a button, the other from another method which afterwards closes the application by doing: [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"sms:"]]; The problem arises only when the application is not closed using the home button, but is closed using the line above. When that happens, the pasteboard contents are lost. I assume this problem has something to do with the object being cleaned up improperly when it closes this way, but have no idea why it is doing that. I have even tried to intentionally leak the object that gets put on the pasteboard, but it still gets lost on the way out. Here is the method: - (IBAction) copyLink { NSString *stringForPasteboard = @"here is the string"; [[UIPasteboard generalPasteboard] setURL:stringForPasteboard]; [stringForPasteboard release]; }
