  • How to map an IDictionary<String, CustomCollectionType> in NHibernate

    - by devonlazarus
    Very close to what I'm trying to do but not quite the answer I think I'm looking for: How to map IDictionary<string, Entity> in Fluent NHibernate I'm trying to implement an IDictionary<String, IList<MyEntity>>and map this collection to the database using NHibernate. I do understand that you cannot map collections of collections directly in NHibernate, but I do need the functionality of accessing an ordered list of elements by key. I've implemented IUserCollectionType for my IList<MyEntity> so that I can use IDictionary<String, MyCustomCollectionType> but am struggling with how to get the map to work as I'd like. Details This is the database I'm trying to model: ------------------------ -------------------- | EntityAttributes | | Entities | ------------------------ ------------------ -------------------- | EntityAttributeId PK | | Attributes | | EntityId PK | <- | EntityId FK | ------------------ | DateCreated | | AttributeId FK | -> | AttributeId PK | -------------------- | AttributeValue | | AttributeName | ------------------------ ------------------ Here are my domain classes: public class Entity { public virtual Int32 Id { get; private set; } public virtual DateTime DateCreated { get; private set; } ... } public class EavEntity : Entity { public virtual IDictionary<String, EavEntityAttributeList> Attributes { get; protected set; } ... } public class EavAttribute : Entity { public virtual String Name { get; set; } ... } public class EavEntityAttribute : Entity { public virtual EavEntity EavEntity { get; private set; } public virtual EavAttribute EavAttribute { get; private set; } public virtual Object AttributeValue { get; set; } ... } public class EavEntityAttributeList : List<EavEntityAttribute> { } I've also implemented the NH-specific custom collection classes IUserCollectionType and PersistentList And here is my mapping so far: <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" ...> <class xmlns="urn:nhibernate-mapping-2.2" name="EavEntity" table="Entities"> <id name="Id" type="System.Int32"> <column name="EntityId" /> <generator class="identity" /> </id> ... <map cascade="all-delete-orphan" collection-type="EavEntityAttributeListType" name="EntityAttributes"> <key> <column name="EntityId" /> </key> <index type="System.String"> <column name="Name" /> </index> <one-to-many class="EavEntityAttributeList" /> </map> </class> </hibernate-mapping> I know the <map> tag is partially correct, but I'm not sure how to get NH to utilize my IUserCollectionType to persist the model to the database. What I'd like to see (and this isn't right, I know) is something like: <map cascade="all-delete-orphan" collection-type="EavEntityAttributeListType" name="EntityAttributes"> <key> <column name="EntityId" /> </key> <index type="System.String"> <column name="Name" /> </index> <list> <index column="DisplayOrder"> <one-to-many class="EntityAttributes"> </list> </map> Does anyone have any suggestions on how to properly map that IDictionary<String, EavEntityAttributeList> collection? I am using Fluent NH so I'll take examples using that library, but I'm hand mappings are just as helpful here.

  • CPU friendly infinite loop

    - by Adi
    Writing an infinite loop is simple: while(true){ //add whatever break condition here } But this will trash the CPU performance. This execution thread will take as much as possible from CPU's power. What is the best way to lower the impact on CPU? Adding some Thread.Sleep(n) should do the trick, but setting a high timeout value for Sleep() method may indicate an unresponsive application to the operating system. Let's say I need to perform a task each minute or so in a console app. I need to keep Main() running in an "infinite loop" while a timer will fire the event that will do the job. I would like to keep Main() with the lowest impact on CPU. What methods do you suggest. Sleep() can be ok, but as I already mentioned, this might indicate an unresponsive thread to the operating system. LATER EDIT: I want to explain better what I am looking for: I need a console app not Windows service. Console apps can simulate the Windows services on Windows Mobile 6.x systems with Compact Framework. I need a way to keep the app alive as long as the Windows Mobile device is running. We all know that the console app runs as long as its static Main() function runs, so I need a way to prevent Main() function exit. In special situations (like: updating the app), I need to request the app to stop, so I need to infinitely loop and test for some exit condition. For example, this is why Console.ReadLine() is no use for me. There is no exit condition check. Regarding the above, I still want Main() function as resource friendly as possible. Let asside the fingerprint of the function that checks for the exit condition.

  • ASP.NET Web Service - how to handle special characters in strings?

    - by Vlorg
    To show this fundamental issue in .NET and the reason for this question, I have written a simple test web service with one method (EditString), and a consumer console app that calls it. They are both standard web service/console applications created via File/New Project, etc., so I won't list the whole code - just the methods in question: Web method: [WebMethod] public string EditString(string s, bool useSpecial) { return s + (useSpecial ? ((char)19).ToString() : ""); } [You can see it simply returns the string s if useSpecial is false. If useSpecial is true, it returns s + char 19.] Console app: TestService.Service1 service = new SCTestConsumer.TestService.Service1(); string response1 = service.EditString("hello", false); Console.WriteLine(response1); string response2 = service.EditString("hello", true); // fails! Console.WriteLine(response2); [The second response fails, because the method returns hello + a special character (ascii code 19 for argument's sake).] The error is: There is an error in XML document (1, 287) Inner exception: "'', hexadecimal value 0x13, is an invalid character. Line 1, position 287." A few points worth mentioning: The web method itself WORKS FINE when browsing directly to the ASMX file (e.g. http://localhost:2065/service1.asmx), and running the method through this (with the same parameters as in the console application) - i.e. displays XML with the string hello + char 19. Checking the serialized XML in other ways shows the special character is being encoded properly (the SERVER SIDE seems to be ok which is GOOD) So it seems the CLIENT SIDE has the issue - i.e. the .NET generated proxy class code doesn't handle special characters This is part of a bigger project where objects are passed in and out of the web methods - that contain string attributes - these are what need to work properly. i.e. we're de/serializing classes. Any suggestions for a workaround and how to implement it? Or have I completely missed something really obvious!!? Thanks in advance... PS. I've not had much luck with getting it to use CDATA tags (does .NET support these out of the box?).

  • How do i refactor this code by using Action<t> or Func<t> delegates

    - by user330612
    I have a sample program, which needs to execute 3 methods in a particular order. And after executing each method, should do error handling. Now i did this in a normal fashion, w/o using delegates like this. class Program { public static void Main() { MyTest(); } private static bool MyTest() { bool result = true; int m = 2; int temp = 0; try { temp = Function1(m); } catch (Exception e) { Console.WriteLine("Caught exception for function1" + e.Message); result = false; } try { Function2(temp); } catch (Exception e) { Console.WriteLine("Caught exception for function2" + e.Message); result = false; } try { Function3(temp); } catch (Exception e) { Console.WriteLine("Caught exception for function3" + e.Message); result = false; } return result; } public static int Function1(int x) { Console.WriteLine("Sum is calculated"); return x + x; } public static int Function2(int x) { Console.WriteLine("Difference is calculated "); return (x - x); } public static int Function3(int x) { return x * x; } } As you can see, this code looks ugly w/ so many try catch loops, which are all doing the same thing...so i decided that i can use delegates to refactor this code so that Try Catch can be all shoved into one method so that it looks neat. I was looking at some examples online and couldnt figure our if i shud use Action or Func delegates for this. Both look similar but im unable to get a clear idea how to implement this. Any help is gr8ly appreciated. I'm using .NET 4.0, so im allowed to use anonymous methods n lambda expressions also for this Thanks

  • Mono-LibreOffice System.TypeLoadException

    - by Marco
    In the past I wrote a C# library to work with OpenOffice and this worked fine both in Windows than under Ubuntu with Mono. Part of this library is published here as accepted answer. In these days I discovered that Ubuntu decided to move to LibreOffice, so I tried my library with LibreOffice latest stable release. While under Windows it's working perfectly, under Linux I receive this error: Unhandled Exception: System.TypeLoadException: A type load exception has occurred. [ERROR] FATAL UNHANDLED EXCEPTION: System.TypeLoadException: A type load exception has occurred. Usually Mono tells us which library can't load, so I can install correct package and everything is OK, but in this case I really don't know what's going bad. I'm using Ubuntu oneiric and my library is compiled with Framework 4.0. Under Windows I had to write this into app.config: <?xml version="1.0"?> <configuration> <startup useLegacyV2RuntimeActivationPolicy="true"> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0,Profile=Client"/> </startup> </configuration> because LibreOffice assemblies uses Framework 2.0 (I think). How can I find the reason of this error to solve it? Thanks UPDATE: Even compiling with Framework 2.0 problem (as expected) is the same. Problem (I think) is that Mono is not finding cli-uno-bridge package (installable on previous Ubuntu releases and now marked as superseded), but I cannot be sure. UPDATE 2: I created a test console application referencing cli-uno dlls on Windows (they are registered in GAC_32 and GAC_MSIL). CONSOLE app static void Main(string[] args) { Console.WriteLine("Starting"); string dir = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location); string doc = Path.Combine(dir, "Liberatoria siti web.docx"); using (QOpenOffice.OpenOffice oo = new QOpenOffice.OpenOffice()) { if (!oo.Init()) return; oo.Load(doc, true); oo.ExportToPdf(Path.ChangeExtension(doc, ".pdf")); } } LIBRARY: using unoidl.com.sun.star.lang; using unoidl.com.sun.star.uno; using unoidl.com.sun.star.container; using unoidl.com.sun.star.frame; using unoidl.com.sun.star.beans; using unoidl.com.sun.star.view; using unoidl.com.sun.star.document; using System.Collections.Generic; using System.IO; using System; namespace QOpenOffice { class OpenOffice : IDisposable { private XComponentContext context; private XMultiServiceFactory service; private XComponentLoader component; private XComponent doc; public bool Init() { Console.WriteLine("Entering Init()"); try { context = uno.util.Bootstrap.bootstrap(); service = (XMultiServiceFactory)context.getServiceManager(); component = (XComponentLoader)service.createInstance("com.sun.star.frame.Desktop"); XNameContainer filters = (XNameContainer)service.createInstance("com.sun.star.document.FilterFactory"); return true; } catch (System.Exception ex) { Console.WriteLine(ex.Message); if (ex.InnerException != null) Console.WriteLine(ex.InnerException.Message); return false; } } } } but I'm not able to see "Starting" !!! If I comment using(...) on application, I see line on console... so I think it's something wrong in DLL. There I'm not able to see "Entering Init()" message on Init(). Behaviour is the same when LibreOffice is not installed and when it is !!! try..catch block is not executed...

  • Raphael Scope Drag n drop multiple paper instances

    - by donald
    I have two Raphael paper instances. In both I want to drag and drop an element (circle). It is important for me to assign both these circles the same id. I expected no problem, as both are in different paper instances and therefore in different scope. What happens is, that somehow both elements react, when I have clicked both elements at least once. If I however give these elements different IDs everything works fine (each element only calls its "start", "drag" and "up" function if draged around). Is this intended behaviour of Raphael and do I have to assign different IDs to the elements in the different paper instances? Hopefully not and you can point me to the right direction :-) Thanks a lot for your Help in advance, Here comes the code: <!doctype html> <html> <head> <meta charset="utf-8" /> <title>DragNDrop</title> <script src="raphael-min.js"></script> </head> <body> <h1>Paper1</h1> <div id="divPaper1" style ="height: 150px; width: 300px; border:thin solid red"></div> <h1>Paper2</h1> <div id="divPaper2" style ="height: 150px; width: 300px; border:thin solid red"></div> <script> start1 = function () { console.log("start1"); } drag1 = function () { console.log("move1"); } up1 = function () { console.log("up1"); } start2 = function () { console.log("start2"); } drag2 = function () { console.log("move2"); } up2 = function () { console.log("up2"); } var paper1 = Raphael("divPaper1", "100%", "100%"); var circle1 = paper1.circle(40, 40, 30); circle1.attr("fill", "yellow"); circle1.id = "circle"; //both circles get the same id circle1.drag(drag1, start1, up1); paper2 = Raphael("divPaper2", "100%", "100%"); var circle2 = paper2.circle(40, 40, 30); circle2.attr("fill", "red"); circle2.id = "circle"; //both circles get the same id circle2.drag(drag2, start2, up2); </script> </body>

  • How can I display an ASP.NET MVC html part from one application in another

    - by Frank Sessions
    We have several asp.net MVC apps in the following setup SecurityApp (root application - handles forms auth for SSO and has a profile edit page) Application1 (virtual directory) Application2 (virtual directory) Application3 (virtual directory) so that domain.com points to SecurityApp and domain.com/Application1 etc point to their associated virtual directories. All of our Single Sign On (SSO) is working properly using forms authentication. Based on the users permissions when logging in a menu that lists their available applications and a logout link will be generated and saved in the cache - this menu displays fine whenever the user is in the SecurityApp (editing their profile) but we cannot figure out how to get the Applications in the virtual directories to display the same application menu. We have tried: 1) Using JSONP to do an request that will return the html for the menu. The ajax call returns the HTML with the html; however, because User.IsAuthenticated is false the menu comes back empty. 2) We created a user control and include it along with the dll's for the SecurityApp project and this works; however, we dont want to have to include all the dlls for the SecurityApp project in every application that we create (along with all the app settings in the web.config) We would like this to be as simple as possible to implement so that anyone creating a new app can add the menu to their application in as few steps as possible... Any ideas? To Clarify - we are using ASP.NET MVC 1.0 since these apps are in production and we do not have the okay to go to ASP.NET MVC 2.0 (unfortunately)

  • weird problem with load () or live () !!

    - by silversky
    I load a page with load () and then I create dinamically a tag. Then I use live() to bind a click event and fires a function. At the end a call unload (). The problem is that when I load the same page again ( without refresh ) when on click the function will be fired twice. If I exit again (again with unload ()) and load the page again on click will fire 3 times and so on .... A sample of my code is: $('#tab').click(function() { $('#formWrap').load('newPage.php'); }); $('div').after('<p class="ctr" ></p>'); $('p.ctr').live('click', function(e) { if($(e.target).is('[k=lf]')) { console.log ('one'); delete ($this); } else if .... }); function delete () { $.post( 'update.php', data); } I have other $.post inside on this page and also on the above live fnc and all work well. The above one also works but like I said on the second load will fire twice and the 3 times and so on ... The weird part for me is that if replece the console with console.log ('two'); save the page and load the page without refresh it will fire on a different rows - one two - if I unload the page replace the console with console.log ('three'); and load again will fire one two and three. I try to use: $.ajax({ url: 'updateDB.php', data: data, type: 'POST', cache:false }); $.ajaxSetup ({ cache: false }); header("Cache-Control: no-cache"); none of this it's working. And I have this problem only on this fnc. What do you think, it could be the reason, it remembers it remembers the previous action and it fires again?

This works fine in IE6 and FF3, but not in Chrome: var log; if(console){ log = console.log; }else{ log = function(){ return; } } I get an "Uncaught TypeError: Illegal Invocation" in Chrome =/ I read about the issue here, where you have to apply a context, which is kind of new to me... and I can't seem to figure how to accomplish the above in all browsers...

  • How to order a HasMany collection by a child property with Fluent NHibernate mapping

    - by Geoff Hardy
    I am using Fluent NHibernate to map the following classes: public abstract class DomainObject { public virtual int Id { get; protected internal set; } } public class Attribute { public virtual string Name { get; set; } } public class AttributeRule { public virtual Attribute Attribute { get; set; } public virtual Station Station { get; set; } public virtual RuleTypeId RuleTypeId { get; set; } } public class Station : DomainObject { public virtual IList<AttributeRule> AttributeRules { get; set; } public Station() { AttributeRules = new List<AttributeRule>(); } } My Fluent NHibernate mappings look like this: public class AttributeMap : ClassMap<Attribute> { public AttributeMap() { Id(o => o.Id); Map(o => o.Name); } } public class AttributeRuleMap : ClassMap<AttributeRule> { public AttributeRuleMap() { Id(o => o.Id); Map(o => o.RuleTypeId); References(o => o.Attribute).Fetch.Join(); References(o => o.Station); } } public class StationMap : ClassMap<Station> { public StationMap() { Id(o => o.Id); HasMany(o => o.AttributeRules).Inverse(); } } I would like to order the AttributeRules list on Station by the Attribute.Name property, but doing the following does not work: HasMany(o => o.AttributeRules).Inverse().OrderBy("Attribute.Name"); I have not found a way to do this yet in the mappings. I could create a IQuery or ICriteria to do this for me, but ideally I would just like to have the AttributeRules list sorted when I ask for it. Any advice on how to do this mapping?

  • How to use reflection to call a method and pass parameters whose types are unknown at compile time?

    - by MandoMando
    I'd like to call methods of a class dynamically with parameter values that are "parsed" from a string input. For example: I'd like to call the following program with these commands: c:myprog.exe MethodA System.Int32 777 c:myprog.exe MethodA System.float 23.17 c:myprog.exe MethodB System.Int32& 777 c:myprog.exe MethodC System.Int32 777 System.String ThisCanBeDone static void Main(string[] args) { ClassA aa = new ClassA(); System.Type[] types = new Type[args.Length / 2]; object[] ParamArray = new object[types.Length]; for (int i=0; i < types.Length; i++) { types[i] = System.Type.GetType(args[i*2 + 1]); // LINE_X: this will obviously cause runtime error invalid type/casting ParamArray[i] = args[i*2 + 2]; MethodInfo callInfo = aa.GetType().GetMethod(args[0],types); callInfo.Invoke(aa, ParamArray); } // In a non-changeable classlib: public class ClassA { public void MethodA(int i) { Console.Write(i.ToString()); } public void MethodA(float f) { Console.Write(f.ToString()); } public void MethodB(ref int i) { Console.Write(i.ToString()); i++; } public void MethodC(int i, string s) { Console.Write(s + i.ToString()); } public void MethodA(object o) { Console.Write("Argg! Type Trapped!"); } } "LINE_X" in the above code is the sticky part. For one, I have no idea how to assign value to a int or a ref int parameter even after I create it using Activator.CreatInstance or something else. The typeConverter does come to mind, but then that requires an explicit compile type casting as well. Am I looking at CLR with JavaScript glasses or there is way to do this?

  • how can we use AsynCallback method of web service in asp.net

    - by sameer
    Hi All, I was going through the proxy class which is generated using wsdl.exe found the asyncmethod like BeginAsynXXX() and EndAsyncXXX(). i understood how to utilize them on Windows application but i was wondering how can we use them in Web Application built using asp.net here is the code for web service client build as windows application.can any tell me how we can do this with web application. using System; using System.Runtime.Remoting.Messaging; using MyFactorize; class TestCallback { public static void Main(){ long factorizableNum = 12345; PrimeFactorizer pf = new PrimeFactorizer(); //Instantiate an AsyncCallback delegate to use as a parameter //in the BeginFactorize method. AsyncCallback cb = new AsyncCallback(TestCallback.FactorizeCallback); // Begin the Async call to Factorize, passing in our // AsyncCalback delegate and a reference // to our instance of PrimeFactorizer. IAsyncResult ar = pf.BeginFactorize(factorizableNum, cb, pf); // Keep track of the time it takes to complete the async call // as the call proceeds. int start = DateTime.Now.Second; int currentSecond = start; while (ar.IsCompleted == false){ if (currentSecond < DateTime.Now.Second) { currentSecond = DateTime.Now.Second; Console.WriteLine("Seconds Elapsed..." + (currentSecond - start).ToString() ); } } // Once the call has completed, you need a method to ensure the // thread executing this Main function // doesn't complete prior to the call-back function completing. Console.Write("Press Enter to quit"); int quitchar = Console.Read(); } // Set up a call-back function that is invoked by the proxy class // when the asynchronous operation completes. public static void FactorizeCallback(IAsyncResult ar) { // You passed in our instance of PrimeFactorizer in the third // parameter to BeginFactorize, which is accessible in the // AsyncState property. PrimeFactorizer pf = (PrimeFactorizer) ar.AsyncState; long[] results; // Get the completed results. results = pf.EndFactorize(ar); //Output the results. Console.Write("12345 factors into: "); int j; for (j = 0; j<results.Length;j++){ if (j == results.Length - 1) Console.WriteLine(results[j]); else Console.Write(results[j] + ", "); } } }

  • InApp Purchase supported content types

    - by Chandan Shetty SP
    In InApp purchase guide i saw these are the supported content types - Digital Books,Virtual poker chips current games, In-game tool or accessory, etc... And non-supported - Physical books, Virtual poker chips for other games, In-game credits for virtual goods, etc... I didn't understand "In-game credits for virtual goods" what is this? In my game i am using some credits to skip certain levels, if credits are not available user can buy credits through inApp purchase then he can skip level... Is it valid supported content type for In-App purchase?

  • iPad: Detecting External Keyboard

    - by StuartW
    My app uses a UIAccessoryView to provide additional keyboard functionality (such as forward/backward tabs and arrows keys) for the virtual keyboard, but that causes UIKeyboardDidShowNotification to fire even when a physical keyboard is present (the accessory appears at the bottom of the screen). I'd like to check if a physical keyboard is attached when handling UIKeyboardWillShowNotification, to prevent the accessory view from appearing and to prevent my custom view from scrolling up (to make room for the non-existent virtual keyboard). I've tried examining the UIKeyboardFrameEndUserInfoKey key, but it returns a real size for the virtual keyboard, in spite of nothing being displayed. Is there any way to detect the presence of a physical keyboard to prevent this unwanted behaviour? Hmm, the plot thickens. I tried disabling the input accessory by returning nil from the inputAccessoryView property of the Responder object which triggers the keyboard. That suppresses UIKeyboardWillShowNotification and UIKeyboardDidShowNotification when there is a physical keyboard present, but keeps these notifications when there is no such keyboard. All good so far. Then I tried re-enabling inputAccessoryView only after UIKeyboardWillShowNotification had been received. This only fires when a virtual keyboard is needed, so it should allow me to reintroduce the accessory view in those circumstances. Or so I thought. Unfortunately, it seems the OS doesn't check inputAccessoryView after UIKeyboardWillShowNotification, so it fails to show the accessory view when it is needed :o( That leaves me with two options: Include the input accessory view, giving extra functionality for virtual keyboard users, but lose the ability to detect a physical keyboard and hence not supporting physical devices; or Exclude the input accessory altogether, preventing most users from accessing the extra keys, but allowing the app to work with a physical keyboard. Not a great choice, so I'm still keen to see if anyone else has addressed this problem!

  • FluentNHibernate Many-To-One References where Foreign Key is not to Primary Key and column names are

    - by Todd Langdon
    I've been sitting here for an hour trying to figure this out... I've got 2 tables (abbreviated): CREATE TABLE TRUST ( TRUSTID NUMBER NOT NULL, ACCTNBR VARCHAR(25) NOT NULL ) CONSTRAINT TRUST_PK PRIMARY KEY (TRUSTID) CREATE TABLE ACCOUNTHISTORY ( ID NUMBER NOT NULL, ACCOUNTNUMBER VARCHAR(25) NOT NULL, TRANSAMT NUMBER(38,2) NOT NULL POSTINGDATE DATE NOT NULL ) CONSTRAINT ACCOUNTHISTORY_PK PRIMARY KEY (ID) I have 2 classes that essentially mirror these: public class Trust { public virtual int Id {get; set;} public virtual string AccountNumber { get; set; } } public class AccountHistory { public virtual int Id { get; set; } public virtual Trust Trust {get; set;} public virtual DateTime PostingDate { get; set; } public virtual decimal IncomeAmount { get; set; } } How do I do the many-to-one mapping in FluentNHibernate to get the AccountHistory to have a Trust? Specifically, since it is related on a different column than the Trust primary key of TRUSTID and the column it is referencing is also named differently (ACCTNBR vs. ACCOUNTNUMBER)???? Here's what I have so far - how do I do the References on the AccountHistoryMap to Trust??? public class TrustMap : ClassMap<Trust> { public TrustMap() { Table("TRUST"); Id(x => x.Id).Column("TRUSTID"); Map(x => x.AccountNumber).Column("ACCTNBR"); } } public class AccountHistoryMap : ClassMap<AccountHistory> { public AccountHistoryMap() { Table("TRUSTACCTGHISTORY"); Id (x=>x.Id).Column("ID"); References<Trust>(x => x.Trust).Column("ACCOUNTNUMBER").ForeignKey("ACCTNBR").Fetch.Join(); Map(x => x.PostingDate).Column("POSTINGDATE"); ); I've tried a few different variations of the above line but can't get anything to work - it pulls back AccountHistory data and a proxy for the Trust; however it says no Trust row with given identifier. This has to be something simple. Anyone? Thanks in advance.
