    - by Soham Dasgupta
    As the title suggests I have two models Products And Orders which are actually two table in my database and I have used a LINQ to SQL class to create there models. Now I wan to create a model named "OrderDetails" which will have properties from both the model like product name and id from product and Order number from orders something like this. An then I want to create a view from this custom model and from which I want to add "CRUD" operation. What should be my approach. And in many scenarios I may have to use data from more than 4 models. Please help. I'm wondering helplessly and I have only two days experience in ASP.NET MVC.

  • Can Fluent NHibernate be configured to use an arbitrary prefix on a property backing field?

    - by dommer
    I'm currently using a convention to (auto)map collection properties to backing fields in Fluent NHibernate. So, I map a property "Orders" to a field "_orders". The convention I'm using to do this is: public class HasManyAccessConvention : IHasManyConvention { public void Apply(IOneToManyCollectionInstance instance) { instance.Access.CamelCaseField(CamelCasePrefix.Underscore); } } Can I write a convention that maps a (collection) property to a field with a non-standard prefix (ignoring whether this is good coding practice for the present)? So, the property "Orders" would be mapped to "xyz_orders", for example. If so, how would I go about this?

  • any ways saving user information without db

    - by hguser
    Hi: I have a application which require login,but the number of user who use the application is no more than 40. And In the application,I get some data from the sql server database where I juse have read permission,also I can not create a table in the db for user validate. ALso I do not think it is a good idea to create a user table in other database on another machine.(for example,I can create a user table in the mysql another machine,but is it desireable just for user validating)? Now I just save the user info in a .properties file,any other good idea? BTW,the programe language used in my application is java.

  • .NET BinarySearch() on ArrayList of custom objects

    - by Alex
    Hi. I have an ArrayList of custom objects that have the following properties: FileName FilePath CurrentFolder TopLevelFolder I then need to do a BinarySearch (or some other quick search) on the FileName property on all the objects in the ArrayList in .NET. In other words, I need to find the object in the ArrayList with the same FileName as the one I'm searching on. Syntax for the ArrayList's BinarySearch is this; but how do you do this for an object's property in the arraylist? public static void FindMyObject( ArrayList myList, Object myObject ) { int myIndex=myList.BinarySearch( myObject ); if ( myIndex < 0 ) Console.WriteLine( "The object to search for ({0}) is not found. The next larger object is at index {1}.", myObject, ~myIndex ); else Console.WriteLine( "The object to search for ({0}) is at index {1}.", myObject, myIndex ); }

  • Unable to sign an imported msi.dll assembly using tlbimp

    - by BigMoose
    This seems so trivial, yet I can't get it to work.. I have an msi.dll wrapper (named Interop.WindowsInstaller.dll) which I need to sign. The way to do it is by signing it upon import (this specific case is even documented in MSDN: http://msdn.microsoft.com/en-us/library/zec56a0w.aspx). BUT - no matter how I do it (w/ or w/o a keyfile, w/ or w/o adding "/delaysign"), the generated assemly's size is always 36,864 bytes and when viewing the DLL's properties there is no "Digital Signatures" tab (needless to say - the DLL is NOT signed). What am I missing here?? (... HELP!...)

  • Mask image does not appear on the screen

    - by Ponty
    I have imported to the library two images and have given them the custom class names MaskImage and MaskedImage. Then i write the code: package { import flash.display.*; public class MaskDemo extends Sprite { // Properties private var sprMaskedImage:Sprite; private var sprMaskImage:Sprite; private var bmMaskedImage:Bitmap; private var bmMaskImage:Bitmap; // Constructor public function MaskDemo() { do_magic(); } // Methods private function do_magic():void { bmMaskedImage = new Bitmap(new MaskedImage(0, 0)); bmMaskImage = new Bitmap(new MaskImage(0, 0)); sprMaskedImage = new Sprite(); sprMaskedImage.addChild(bmMaskedImage); sprMaskImage = new Sprite(); sprMaskImage.addChild(bmMaskImage); sprMaskedImage.mask = sprMaskImage; this.addChild(sprMaskImage); } } } But it does not appear anything on the display. Any ideas why is happening that?

  • Is an object still connected to a list after FirstOrDefault?

    - by Cynthia
    Here's my code: Event thisEvent = (from i in list where (i.eventID == eventID) select i).FirstOrDefault(); if (thisEvent != null) { thisEvent.eventResolved = resolved; thisEvent.eventSequence.Add(item); } "list" is a collection of IEnumerable, i.e. IEnumerable<Event> list; What I'm wondering is: after creating thisEvent using FirstOrDefault, is thisEvent still connected to list? In other words, when I change the two properties, eventResolved and eventSequence, is "list" actually changed, or is thisEvent just some totally disconnected copy of an item in "list"?

I tried all the alignment properties, i must be doing something wrong. Any ideas???

  • Azure Blobs - ArgumentNullException when calling UploadFile()

    - by Ariel
    I’m getting the following exception when trying to upload a file with the following code: string encodedUrl = "videos/Sample.mp4" CloudBlockBlob encodedVideoBlob = blobClient.GetBlockBlobReference(encodedUrl); Log(string.Format("Got blob reference for {0}", encodedUrl), EventLogEntryType.Information); encodedVideoBlob.Properties.ContentType = contentType; encodedVideoBlob.Metadata[BlobProperty.Description] = description; encodedVideoBlob.UploadFile(localEncodedBlobPath); I see the "Got blob reference" message, so I assume the reference resolves correctly. Void Run() C:\Inter\Projects\PoC\WorkerRole\WorkerRole.cs (40) System.ArgumentNullException: Value cannot be null. Parameter name: value at Microsoft.WindowsAzure.StorageClient.Tasks.Task`1.get_Result() at Microsoft.WindowsAzure.StorageClient.Tasks.Task`1.ExecuteAndWait() at Microsoft.WindowsAzure.StorageClient.CloudBlob.UploadFromStream(Stream source, BlobRequestOptions options) at Microsoft.WindowsAzure.StorageClient.CloudBlob.UploadFile(String fileName, BlobRequestOptions options) at EncoderWorkerRole.WorkerRole.ProcessJobOutput(IJob job, String videoBlobToEncodeUrl) in C:\Inter\Projects\PoC\WorkerRole\WorkerRole.cs:line 144 at EncoderWorkerRole.WorkerRole.Run() in C:\Inter\Projects\PoC\WorkerRole\WorkerRole.cs:line 40 Interestingly, I'm running that same snippet from an on-premises server i.e., outside of Azure and it works correctly.

  • How to Iterate a Resharper Template ?.

    - by sree
    I have a small Resharper Template I have written for Null check of a function Parameter (C#). Check.IsNotNull($param$, "$param$"); - Suggest Parameter - #1 I can now null check the function paramters one by one. But I want to be able to null check all the paramters at once through a template. Is it Possible in Resharper?. Is there someting like a "$Foreach" using which I can loop through parameter variables and write the code to check them one by one ?. (without writing out the foreach into the code) I see that the "Alt + Ins" does something similar. (Taking all Properties on the class and making them as parameters of a constructor). So hoping that there's a way out.

  • InfoPath Getting SharePoint Group Information

    - by anon
    I have an InfoPath form embedded in an aspx page on a SharePoint site. How do I bind the SharePoint user groups to a drop-down list on my form? What I've tried so far is to create a data connection to a web service (method GetGroupCollectionFromWeb) to pull the data. Next, I open the list box properties, select "Look up values from an external data source", select the data source, assign the entries, and I get the following error: "You must select a repeating group or field." What I don't understand is that since the method I am calling is called GetGroupCollectionFromWeb, isn't the return value a collection? And aren't collections repeating by definition? What am I missing, and is there a workaround? Thank you.

  • Linq to SQl Stored Procedure Problem( it can't figure out the return type)

    - by chobo2
    Hi I have this SP USE [Test] GO SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE PROCEDURE [dbo].[UsersInsert](@UpdatedProdData XML) AS INSERT INTO dbo.UserTable(UserId,UserName,LicenseId,Password,PasswordSalt,Email,IsApproved,IsLockedOut,CreateDate, LastLoginDate,LastLockOutDate,FailedPasswordAttempts,RoleId) SELECT @UpdatedProdData.value('(/ArrayOfUsers/Users/UserId)[1]', 'uniqueidentifier'), @UpdatedProdData.value('(/ArrayOfUsers/Users/UserName)[1]', 'varchar(20)'), @UpdatedProdData.value('(/ArrayOfUsers/Users/LicenseId)[1]', 'varchar(50)'), @UpdatedProdData.value('(/ArrayOfUsers/Users/Password)[1]', 'varchar(128)'), @UpdatedProdData.value('(/ArrayOfUsers/Users/PasswordSalt)[1]', 'varchar(128)'), @UpdatedProdData.value('(/ArrayOfUsers/Users/Email)[1]', 'varchar(50)'), @UpdatedProdData.value('(/ArrayOfUsers/Users/IsApproved)[1]', 'bit'), @UpdatedProdData.value('(/ArrayOfUsers/Users/IsLockedOut)[1]', 'bit'), @UpdatedProdData.value('(/ArrayOfUsers/Users/CreateDate)[1]', 'datetime'), @UpdatedProdData.value('(/ArrayOfUsers/Users/LastLoginDate)[1]', 'datetime'), @UpdatedProdData.value('(/ArrayOfUsers/Users/LastLockOutDate)[1]', 'datetime'), @UpdatedProdData.value('(/ArrayOfUsers/Users/FailedPasswordAttempts)[1]', 'int'), @UpdatedProdData.value('(/ArrayOfUsers/Users/RoleId)[1]', 'int') Now this SP creates just fine. It's when I go to VS2010 and try to drag this SP in my method panel of my linq to sql file in design view. It tells me that it can't figure out the return type. I try to go to the properties but it does not have "none" as a choice and I can't type it in. It should be "none" so how do I set it to "none"?

  • iPhone memory management: a release after setting self.someProperty = nil

    - by ddawber
    I am reading the LazyTableImages code that Apple have released and they do something to this effect (in an NSOperation subclass): - (void)dealloc { [myProperty release]; [myProperty2 release]; } - (void)main { // // Parse operation undertaken here // self.myProperty = nil; self.myProperty2 = nil; } My thinking is that they do this in case dealloc is called before setting properties to nil. Is my thinking correct here? Are the releases unnecessary, as self.myProperty = nil effectively releases myProperty? One thing I have noticed in this code is that they don't release all retained objects in dealloc, only some of them, which is really the cause for my confusion. Cheers

  • Finding Windows printer driver name using API

    - by Scott Bussinger
    I can't seem to find an API call that returns the driver name for a Windows printer. Note that I'm not talking about the friendly name of the printer in the printer folder, I'm talking about the name of actual driver being used as shown on the "Advanced" tab when you look at the printer properties: I'm trying to detect when I'm printing to the "Generic / Text Only" driver regardless of what name the user chooses for the printer. It doesn't seem like this should be hard, but I can't find it in the DEVMODE structure or anyplace else I've thought to look for it. Thanks for the help!

  • How do you resolve the common collsision between type name and object name?

    - by Catskul
    Since the convention is to capitalize the first letter of public properties, the old c++ convention of initial capital for type names, and initial lowercase for non-type names does not prevent the classic name collision class FooManager { public BarManager BarManager { get; set; } // Feels very wrong. // Recommended naming convention? public int DoIt() { return Foo.Blarb + Foo.StaticBlarb; // 1st and 2nd Foo are two // different symbols } } class BarManager { public int Blarb { get; set; } public static int StaticBlarb { get; set; } } It seems to compile, but feels so wrong. Is there a recommend naming convention to avoid this?

  • MSMQ empty object on message body

    - by Owen
    Ok, so I'm very VERY new to MSMQ and I'm already confused. I have created a private queue and added a few messages to it, all good so far. BUT when I retrieve the messages back from the queue the message body contains a empty object of the type I added. By this I don't mean that the body is null, it does have a reference to a type of the object that I added, but it's not instantiated so all the properties are in their null or default state. This is the code I use to add to the queue: using (var mQueue = new MessageQueue(QueueName)) { var msg = new Message(observation) { Priority = MessagePriority.Normal, UseJournalQueue = true, AcknowledgeType = AcknowledgeTypes.FullReceive, }; mQueue.Send(msg); } And this is the code that dequeues the messages: using (var mQueue = new MessageQueue(QueueName)) { mQueue.MessageReadPropertyFilter.SetAll(); ((XmlMessageFormatter)mQueue.Formatter).TargetTypes = new[] { typeof(Observation) }; var msg = mQueue.Receive(new TimeSpan(0, 0, 5)); var observation = (Observation)msg.Body; return observation; }

  • Basic Hibernate question using and sql query

    - by Aerosteak
    Hello Sorry if this is basic but I cannot find the solution anywhere. I have an java Object ‘Person’ with 3 properties firstname,lastname and username. I have an Oracle Store procedure returning a Resultset with the 3 column. All works fine for that. Now I have another StoreProcedure that will only return firstname and lastname but not username. I get the following error : « could not read column value from result set username. » Hibernate tries to fetch the username property from the resultset. If I remove the property username, then it works. Do I have to Create a Special Pojo for Each type of resultset or can I tell Hibernate what to map for each result set? Please help.

  • How can a string timestamp with hours 0 to 24 be parsed

    - by user897052
    I am trying to parse a string timestamp of format "yyyyMMddHHmmss" with DateTime.ParseExact(). The catch is I must allow for an hour value of "24" (i.e. hours can be from 0 to 24; Note: I can't control the input values.) and, of course, that results in an exception. Are there any settings/properties I can set instead of manually parsing/using regex's? If not, any efficient parsing ideas? ex. DateTime.ParseExact("20120911240000", "yyyyMMddHHmmss", System.Globalization.CultureInfo.InvariantCulture); hour 24 means hour 0 of next day (so day + 1, hour = 0)

  • Weird exception with OLEDB Parameter Insert

    - by Seamus MacKenzie
    Getting a strange error when trying to insert data into an Access database using parameters. the line where I am getting a problem is :- thisCommand.CommandText = "INSERT INTO Events (Venue_ID, Date_Start, Date_End, Time_Start, Time_End, Name, Description, Event_Type, Buy_Tickets_URL) VALUES (@VenID, @DStart, @DEnd, @evTime, @evTime, @Name, @Des, @EvType, @SysUrl);"; string desc = GetDesc(rec.EvName); thisCommand.Parameters.AddWithValue("@Des", desc); thisCommand.ExecuteNonQuery(); None of the other parameters cause a problem but when trying to insert data to the description field I get a database exception saying the field is too small to accept the amount of data. The problem is my program is only trying to insert 3 characters when it throws the error and the Description field is a memo so should be able to hold up to 65000+ characters. When inserting a value manually in the CommandText everything works fine so it must be something to do with the parameter properties.

  • Modifying object in AfterInsert / AfterUpdate

    - by Jean Barmash
    I have a domain object that holds results of a calculation based on parameters that are properties of the same domain object. I'd like to make sure that any time parameters get changed by the user, it recalculates and gets saved properly into the database. I am trying to do that with afterInsert (to make sure calculation is correct in the first place), and afterUpdate. However, since my calculation is trying to modify the object itself, it's not working - throwing various hibernate exceptions. I tried to put the afterUpdate code into a transaction, but that didn't help. I am afraid I am getting into a circular dependency issues here. The exception I am getting right now is: org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [esc.scorecard.PropertyScorecard#27] Are the GORM events designed for simpler use cases? I am tempted to conclude that modifying the object you are in the middle of saving is not the way to go.

  • Getting unique items from NSMutableArray

    - by Gidogeek
    Hi Guys, I have a question about Objective-C today involving NSMutableArray. Coming from a .net/c# background I'm having some trouble working with these things. Let's say I have an object called "Song" My song has 3 properties: Title Artist Genre I have a NSMutableArray or NSArray wich holds all my Song objects. How would I go about trying to 'query' my array to get a new array with only (Unique) Artists or Genre's. Where as in .net you would write a simple LINQ query with a DISTINCT clause, how would one solve this in Objective-C ? I'm guessing with predicates but am struggling to find a solution. Thanks in advance.

  • What's the fastest way to compare two objects in PHP?

    - by johnnietheblack
    Let's say I have an object - a User object in this case - and I'd like to be able to track changes to with a separate class. The User object should not have to change it's behavior in any way for this to happen. Therefore, my separate class creates a "clean" copy of it, stores it somewhere locally, and then later can compare the User object to the original version to see if anything changed during its lifespan. Is there a function, a pattern, or anything that can quickly compare the two versions of the User object? Option 1 Maybe I could serialize each version, and directly compare, or hash them and compare? Option 2 Maybe I should simply create a ReflectionClass, run through each of the properties of the class and see if the two versions have the same property values? Option 3 Maybe there is a simple native function like objects_are_equal($object1,$object2);? What's the fastest way to do this?

  • Question regrarding declaring a property

    - by Simon
    Hi. We declare properties using the @property keyword and synthesize it in the implementation file. My question is, What if I declare a property using the @property keyword and also declare a variable in the interface block with the same name? For example, consider the following code, Interface: @interface myClass : NSObject { NSString *myClass_name; // LINE 1 } @property(nonatomic, retain) NSString *myClass_name; // LINE 2 @end Implementation: @implementation myClass @synthesize myClass_name @end Declaring myClass_name in LINE 1 will make any problem? Like any reference problem or any unnecessary memory consumption problem?
