    - by user195114
    I want the users to type their text in the given textbox and on clicking on createNewFile Button, a SaveAs Dialogbox should popup and the users should browse through the location and save the file as desired. I have tried some thing but (1) the dialog box goes behind the application (2) when run, dialogbox opens 3 times, means it executes 3 times REPLY TO THE POST protected void btnNewFile_Click(object sender, EventArgs e) { StreamWriter sw = null; try { SaveFileDialog sdlg = new SaveFileDialog(); DialogResult result = sdlg.ShowDialog(); sdlg.InitialDirectory = @"C:\"; sdlg.AddExtension = true; sdlg.CheckPathExists = true; sdlg.CreatePrompt = false; sdlg.OverwritePrompt = true; sdlg.ValidateNames = true; sdlg.ShowHelp = true; sdlg.DefaultExt = "txt"; // sdlg.ShowDialog = Form.ActiveForm; string file = sdlg.FileName.ToString(); string data = txtNewFile.Text; if (sdlg.ShowDialog() == DialogResult.OK) { sw.WriteLine(txtNewFile.Text); sw.Close(); } if (sdlg.ShowDialog() == DialogResult.Cancel) { sw.Dispose(); } //Save(file, data); } catch { } finally { if (sw != null) { sw.Close(); } } } private void Save(string file, string data) { StreamWriter writer = new StreamWriter(file); SaveFileDialog sdlg1 = new SaveFileDialog(); try { if (sdlg1.ShowDialog() == DialogResult.OK) { writer.Write(data); writer.Close(); } else writer.Dispose(); } catch (Exception xp) { MessageBox.Show(xp.Message); } finally { if (writer != null) { writer.Close(); } } } I have tried this.

  • Redirecting users on select from autocomplete?

    - by juno-2
    Hi, i'm trying to implement the jquery autocomplete plugin. I've got it up and running, but something is not working properly. Basically i have a autocomplete-list of employees. The list is generated from a table in a sql-database (employee_names and employee_ID), using a VB.NET handler (.ashx file). The data is formatted as: employee_name-employee_ID. So far so good and all employees are listed in autocomplete. The problem is that i don't know how to redirect a user to a certain page (for example employee_profile.aspx) when they've selected an employee from autocomplete. This is my redirect-code, but it ain't working like it should: $('#fname2').result(function(event, data, formatted) { location.href = "employee_profile.aspx?id=" + data }); For example; a user selects It will redirect a user to employee_profile.aspx?id=name of employee-id of employee (for example: employee_profile.aspx?id=John Doe-91210) instead of employee_profile.aspx?id=91210. I know i can strip the employee_ID with: formatResult: function(data, value) { return value.split("-")[1]; } }); But i do not know how to pass that employee_ID to the redirect-page.. Here my whole code: $().ready(function() { $("#fname2").autocomplete("AutocompleteData.ashx", { minChars: 3, selectFirst: false, formatItem: function(data, i, n, value) { return value.split("-")[0]; }, //Not used, just for splitting employee_ID //formatResult: function(data, value) { // return value.split("-")[1]; //} }); $('#fname2').result(function(event, data, formatted) { location.href = "employee_profile.aspx?id=" + data }); }); I know i'm very close and it should be something really simple, but can anyone help me out?

  • Problem Activating Sharepoint Timer Job

    - by Ben Robinson
    I have created a very simple sharepoint timer job. All i want it to do is iterate through a list and update each list item so that it triggers an existing workflow that works fine. In other words all i am trying to do is work around the limitation that workflows cannot be triggered on a scheduled basis. I have written a class that inherits from SPJobDefinition that does the work and i have a class that inherits from SPFeatureReceiver to install and activate it. I have created the feature using SPVisualdev that my coleagues have used in the past for other SP development. My Job class is below: public class DriverSafetyCheckTrigger : SPJobDefinition { private string pi_SiteUrl; public DriverSafetyCheckTrigger(string SiteURL, SPWebApplication WebApp):base("DriverSafetyCheckTrigger",WebApp,null, SPJobLockType.Job) { this.Title = "DriverSafetyCheckTrigger"; pi_SiteUrl = SiteURL; } public override void Execute(Guid targetInstanceId) { using (SPSite siteCollection = new SPSite(pi_SiteUrl)) { using (SPWeb site = siteCollection.RootWeb) { SPList taskList = site.Lists["Driver Safety Check"]; foreach(SPListItem item in taskList.Items) { item.Update(); } } } } } And the only thing in the feature reciever class is that i have overridden the FeatureActivated method below: public override void FeatureActivated(SPFeatureReceiverProperties Properties) { SPSite site = Properties.Feature.Parent as SPSite; // Make sure the job isn't already registered. foreach (SPJobDefinition job in site.WebApplication.JobDefinitions) { if (job.Name == "DriverSafetyCheckTrigger") job.Delete(); } // Install the job. DriverSafetyCheckTrigger oDriverSafetyCheckTrigger = new DriverSafetyCheckTrigger(site.Url, site.WebApplication); SPDailySchedule oSchedule = new SPDailySchedule(); oSchedule.BeginHour = 1; oDriverSafetyCheckTrigger.Schedule = oSchedule; oDriverSafetyCheckTrigger.Update(); } The problem i have is that when i try to activate the feature it throws a NullReferenceException on the line oDriverSafetyCheckTrigger.Update(). I am not sure what is null in this case, the example i have followed for this is this tutorial. I am not sure what I am doing wrong.

  • How to transfer objects through the header in WCF

    - by Michael
    I'm trying to transfer some user information in the header of the message through message inspectors. I have created a behavior which adds the inspector to the service (both client and server). But when I try to communicate with the service I get the following error: XmlException: Name cannot begin with the '<' character, hexadecimal value 0x3C. I have also get exception telling me that DataContracts where unexpected. Type 'System.DelegateSerializationHolder+DelegateEntry' with data contract name 'DelegateSerializationHolder.DelegateEntry:http://schemas.datacontract.org/2004/07/System' is not expected. Consider using a DataContractResolver or add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list of known types passed to DataContractSerializer. The thing is that my object contains other objects which are marked as DataContract and I'm not interested adding the KnownType attribute for those types. Another problem might be that my object to serialize is very restricted in form of internal class and internal properties etc. Can anyone guide me in the right direction. What I'm I doing wrong? Some code: public virtual object BeforeSendRequest(ref Message request, IClientChannel channel) { var header = MessageHeader.CreateHeader("<name>", "<namespace>", object); request.Headers.Add(header); return Guid.NewGuid(); }

  • @OneToMany and composite primary keys?

    - by Kris Pruden
    Hi, I'm using Hibernate with annotations (in spring), and I have an object which has an ordered, many-to-one relationship which a child object which has a composite primary key, one component of which is a foreign key back to the id of the parent object. The structure looks something like this: +=============+ +================+ | ParentObj | | ObjectChild | +-------------+ 1 0..* +----------------+ | id (pk) |-----------------| parentId | | ... | | name | +=============+ | pos | | ... | +================+ I've tried a variety of combinations of annotations, none of which seem to work. This is the closest I've been able to come up with: @Entity public class ParentObject { @Column(nullable=false, updatable=false) private String id; @OneToMany(mappedBy="object", fetch=FetchType.EAGER) @IndexColumn(name = "pos", base=0) private List<ObjectChild> attrs; ... } @Entity public class ChildObject { @Embeddable public static class Pk implements Serializable { @Column(nullable=false, updatable=false) private String objectId; @Column(nullable=false, updatable=false) private String name; @Column(nullable=false, updatable=false) private int pos; ... } @EmbeddedId private Pk pk; @ManyToOne @JoinColumn(name="parentId") private ParentObject parent; ... } I arrived at this after a long bout of experimentation in which most of my other attempts yielded entities which hibernate couldn't even load for various reasons. The error I get when I try to read one of these objects (they seem to save OK), I get an error of this form: org.hibernate.exception.SQLGrammarException: could not initialize a collection: ... And the root cause is this: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'attrs0_.id' in 'field list' I'm sure I'm missing something simple, but the documentation is not clear on this matter, and I haven't been able to find any examples of this anywhere else. Thanks!

  • How to effectively use WorkbookBeforeClose event correctly?

    - by Ahmad
    On a daily basis, a person needs to check that specific workbooks have been correctly updated with Bloomberg and Reuters market data ie. all data has pulled through and that the 'numbers look correct'. In the past, people were not checking the 'numbers' which led to inaccurate uploads to other systems etc. The idea is that 'something' needs to be developed to prevent the use from closing/saving the workbook unless he/she has checked that the updates are correct/accurate. The numbers look correct action is purely an intuitive exercise, thus will not be coded in any way. The simple solution was to prompt users prior to closing the specific workbook to verify that the data has been checked. Using VSTO SE for Excel 2007, an Add-in was created which hooks into the WorkbookBeforeClose event which is initialised in the add-in ThisAddIn_Startup private void wb_BeforeClose(Xl.Workbook wb, ref bool cancel) { //.... snip ... if (list.Contains(wb.Name)) { DailogResult result = MessageBox.Show("some message", "sometitle", MessageBoxButtons.YesNo); if (result != DialogResult.Yes) { cancel = true; // i think this prevents the whole application from closing } } } I have found the following ThisApplication.WorkbookBeforeSave vs ThisWorkbook.Application.WorkbookBeforeSave which recommends that one should use the ThisApplication.WorkbookBeforeClose event which I think is what I am doing since will span all files opened. The issue I have with the approach is that assuming that I have several files open, some of which are in my list, the event prevents Excel from closing all files sequentially. It now requires each file to be closed individually. Am I using the event correctly and is this effective & efficient use of the event? Should I use the Application level event or document level event? Is there a way to prevent the above behaviour? Any other suggestions are welcomed VS 2005 with VSTO SE

In table1 i have columns as AddressID(Primary Key),Address1,Address2,City In table2 i have columns as ContactID(Primary Key),AddressID(Foriegn Key),Last Name,First Name. By using join operation i can retrive data from both the tables. I created a Model in my MVC Application.I can see both the tables in enitity editor.

  • "User Friendly" .net compatible Regex/Text matching tools?

    - by Binary Worrier
    Currently in our software we provide a hook where we call a DLL built by our clients to parse information out of documents we are processing (the DLL takes in some text (or a file) and returns a list of name/value pairs). e.g. We're given a Word doc or Text file to Archive. We do various things to the file, and call a DLL that will return "pertinent" information about the file. Among other things we store that "pertinent" data for posterity. What is considered "pertinent" depends on the client and the type of the document, we don't care, we get it and store it. I've been asked to develop a user friendly "something" that will allow a non-programmer user to "configure" how to get this data from a plain text document (<humor>The user story ends with the helpful suggestion/query "We could use regex for this?"</humor>) It's safe to assume that a list of regex's isn't going to cut this, I've written some of these parsers for customers, the regex's to do these would be hedious and some of them can't be done by regex's. Also one of the requirements above is "user friendly" which negates anything that has users seeing or editing regex expressions. As you can guess, I don't have a fortune of time to do this, and am wondering is there anything out there that I can plug in to our app that has a nice front end and does exactly what I need? :) No? Whadda mean no! . . . sigh Ok then failing that, anything out there that "visually" builds regex's and/or other pattern matching expressions, and then allows one to run those expressions against some text? The MS BRE will do what I want, but I need something prettier that looks less like code. Thanks guys,

  • SharpPcap issue

  • Best practice when using WebMethods and session

    - by Abdel Olakara
    Hi all, I want to reduce postback in one of my application page and use ajax instead. I used the WebMethod to do so.. I have a static WebMethod that needs to access the session variables and modify. and on the client side, i am calling this method using jQuery. I tried accessing the session as follows: [WebMethod] public static void TestWebMethod() { if (HttpContext.Current.Session["pitems"] != null) { log.Debug("Using the existing list"); Product prod = (Product)HttpContext.Current.Session["pitems"]; List<Configs> confs = cart.GetConfigs(); foreach (Configs citem in confis) { log.Info(citem.Description); } } log.Info("Inside the method!"); } The values are displayed correctly and seems to work.. but i would like to know if this practice is allowed as the method is a static methods and would like to know how it will behave if multiple people access the application. I would also like to know how developers do these kind of tasks in ASP if this is not the right method. Thanks in advance for your suggestions and ideas, Abdel Olakara

  • Python Pre-testing for exceptions when coverage fails

    - by Tal Weiss
    I recently came across a simple but nasty bug. I had a list and I wanted to find the smallest member in it. I used Python's built-in min(). Everything worked great until in some strange scenario the list was empty (due to strange user input I could not have anticipated). My application crashed with a ValueError (BTW - not documented in the official docs). I have very extensive unit tests and I regularly check coverage to avoid surprises like this. I also use Pylint (everything is integrated in PyDev) and I never ignore warnings, yet I failed to catch this bug before my users did. Is there anything I can change in my methodology to avoid these kind of runtime errors? (which would have been caught at compile time in Java / C#?). I'm looking for something more than wrapping my code with a big try-except. What else can I do? How many other build in Python functions are hiding nasty surprises like this???

  • What are the most interesting equivalences arising from the Curry-Howard Isomorphism?

    - by Tom
    I came upon the Curry-Howard Isomorphism relatively late in my programming life, and perhaps this contributes to my being utterly fascinated by it. It implies that for every programming concept there exists a precise analogue in formal logic, and vice versa. Here's an "obvious" list of such analogies, off the top of my head: program/definition | proof type/declaration | proposition inhabited type | theorem function | implication function argument | hypothesis/antecedent function result | conclusion/consequent function application | modus ponens recursion | induction identity function | tautology non-terminating function | absurdity tuple | conjunction (and) disjoint union | exclusive disjunction (xor) parametric polymorphism | universal quantification So, to my question: what are some of the more interesting/obscure implications of this isomorphism? I'm no logician so I'm sure I've only scratched the surface with this list. For example, here are some programming notions for which I'm unaware of pithy names in logic: currying | "((a & b) => c) iff (a => (b => c))" scope | "known theory + hypotheses" And here are some logical concepts which I haven't quite pinned down in programming terms: primitive type? | axiom set of valid programs? | theory ? | disjunction (or)

  • Formatting inline many-to-many related models presented in django admin

    - by Jonathan
    I've got two django models (simplified): class Product(models.Model): name = models.TextField() price = models.IntegerField() class Invoice(models.Model): company = models.TextField() customer = models.TextField() products = models.ManyToManyField(Product) I would like to see the relevant products as a nice table (of product fields) in an Invoice page in admin and be able to link to the individual respective Product pages. My first thought was using the admin's inline - but django used a select box widget per related Product. This isn't linked to the Product pages, and also as I have thousands of products, and each select box independently downloads all the product names, it quickly becomes unreasonably slow. So I turned to using ModelAdmin.filter_horizontal as suggested here, which used a single instance of a different widget, where you have a list of all Products and another list of related Products and you can add\remove products in the later from the former. This solved the slowness, but it still doesn't show the relevant Product fields, and it ain't linkable. So, what should I do? tweak views? override ModelForms? I Googled around and couldn't find any example of such code...

  • Aliasing Resources (WPF)

    - by Noldorin
    I am trying to alias a resource in XAML, as follows: <UserControl.Resources> <StaticResourceExtension x:Key="newName" ResourceKey="oldName"/> </UserControl.Resources> oldName simply refers to a resource of type Image, defined in App.xaml. As far as I understand, this is the correct way to do this, and should work fine. However, the XAML code gives me the superbly unhelpful error: "The application XAML file failed to load. Fix errors in the application XAML before opening other XAML files." This appears when I hover over the StaticResourceExtension line in the code (which has a squiggly underline). Several other errors are generated in the actual Error List, but seem to be fairly irrelevant and nonsenical (such messages as "The name 'InitializeComponent' does not exist in the current context"), as they all disappear when the line is removed. I'm completely stumped here. Why is WPF complaining about this code? Any ideas as to a resolution please? Note: I'm using WPF in .NET 3.5 SP1. Update 1: I should clairfy that I do receive compiler errors (the aforementioned messages in the Error List), so it's not just a designer problem. Update 2: Here's the relevant code in full... In App.xaml (under Application.Resource): <Image x:Key="bulletArrowUp" Source="Images/Icons/bullet_arrow_up.png" Stretch="None"/> <Image x:Key="bulletArrowDown" Source="Images/Icons/bullet_arrow_down.png" Stretch="None"/> And in MyUserControl.xaml (under UserControl.Resources): <StaticResourceExtension x:Key="columnHeaderSortUpImage" ResourceKey="bulletArrowUp"/> <StaticResourceExtension x:Key="columnHeaderSortDownImage" ResourceKey="bulletArrowDown"/> These are the lines that generate the errors, of course.

  • IntelliJ IDEA plugin development: Get classes VirtualFile (or paths) for a specific source VirtualFi

    - by Ran Biron
    Hi all. This is a cross-post from http://www.jetbrains.net/devnet/message/5264436#5264436 - I failed to get any answer on that forum for two weeks now, so I'm re-asking it here (please don't flame). This question refers to plugin development for the IntelliJ IDEA IDE, specifically targeting java development: Is there any API to get the list of .class files for given source file? I'm trying to write a plugin that creates a binary patch jar based on a changelist. I've managed to get the changelist and, from it, a list of source files (VirtualFile). Now I'm trying to get the compiled class files for these source files (I don't mind preforming a "make" or relying on the previous compile output). I've played a bit with ProjectFileIndex but could only find the classes root. I'd hate to do a "dumb" path-based search because inner classes (and inner anonymous classes) would make it difficult to get correctly. Is there such an API? Or am I doomed to parse the paths? Thanks, Ran.

  • Manually listing objects in Django (problem with field ordering)

    - by Chris
    I'm having some trouble figuring out the best/Djangoic way to do this. I'm creating something like an interactive textbook. It has modules, which are more or less like chapters. Each module page needs to list the topics in that module, grouped into sections. My question is how I can ensure that they list in the correct order in the template? Specifically: 1) How to ensure the sections appear in the correct order? 2) How to ensure the topics appear in the correct order in the section? I imagine I could add a field to each model purely for the sake of ordering, but the problem with that is that a topic might appear in different modules, and in whatever section they are in there they would again have to be ordered somehow. I would probably give up and do it all manually were it not for the fact that I need to have the Topic as object in the template (or view) so I can mark it up according to how the user has labeled it. So I suppose my question is really to do with whether I should create the contents pages manually, or whether there is a way of ordering the query results in a way I haven't thought of. Thanks for your help!

  • Silverlight WCF service consuming inherited types in datacontract

    - by RemotecUk
    Hi, Im trying to consume a WCF service in silverlight... What I have done is to create two seperate assemblies for my datacontracts... Assembly that contains all of my types marked with data contracts build against .Net 3.5 A Silverlight assembly which links to files in the 1st assembly. This means my .Net app can reference assembly 1 and my silverlight app assembly 2. This works fine and I can communicate across the service. The problems occur when I try to transfer inherited classed. I have the following class stucture... IFlight - an interface for all types of flights. BaseFlight : IFlight - a baseflight flight implements IFlight AdhocFlight : BaseFlight, IFlight - an adhoc flight inherits from baseflight and also implements IFlight. I can successfully transfer base flights across the service. However I really need to be able to transfer objects of IFlight across the interface as I want one operation contract that can transfer many types of flight... public IFlight GetFlightBooking() { AdhocFlight af = new AdhocFlight(); return af; } ... should work I think? However I get the error: "The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error." Any ideas would be appreciated.

  • How to use references, avoid header bloat, and delay initialization?

    - by Kyle
    I was browsing for an alternative to using so many shared_ptrs, and found an excellent reply in a comment section: Do you really need shared ownership? If you stop and think for a few minutes, I'm sure you can pinpoint one owner of the object, and a number of users of it, that will only ever use it during the owner's lifetime. So simply make it a local/member object of the owners, and pass references to those who need to use it. I would love to do this, but the problem becomes that the definition of the owning object now needs the owned object to be fully defined first. For example, say I have the following in FooManager.h: class Foo; class FooManager { shared_ptr<Foo> foo; shared_ptr<Foo> getFoo() { return foo; } }; Now, taking the advice above, FooManager.h becomes: #include "Foo.h" class FooManager { Foo foo; Foo& getFoo() { return foo; } }; I have two issues with this. First, FooManager.h is no longer lightweight. Every cpp file that includes it now needs to compile Foo.h as well. Second, I no longer get to choose when foo is initialized. It must be initialized simultaneously with FooManager. How do I get around these issues?

  • OpenGL - drawing 2D polygons shapes with texture

    - by plonkplonk
    I am trying to make a few effects in a C+GL game. So far I draw all my sprites as a quad, and it works. However, I am trying to make a large ring appear at times, with a texture following that ring, as it takes less memory than a quad with the ring texture inside. The type of ring I want to make is not a round-shaped GL mesh ring (the "tube" type) but a "paper" 2D ring. That way I can modify the "width" of the ring, getting more of the effect than a simple quad+ring texture. So far all my attempts have been...kind of ridiculous, as I don't understand GL's coordinates too well (and I can't really understand the available documentation...I am just a designer with no coder help or background. A n00b, basically). glBegin(GL_POLYGON); for(i = 0;i < 360; i += 10){ glTexCoord2f(0, 0); glVertex2f(Cos(i)*(H-10),Sin(i)H); glTexCoord2f(0, HP); glVertex2f(Sin(i)(H-10),Cos(i)*(H-10)); glTexCoord2f(WP, HP); glVertex2f(Cos(i)H,Sin(i)(H-10)); glTexCoord2f(WP, 0); glVertex2f(Sin(i)*H,Cos(i)*H); } glEnd(); This is my last attempt, and it seems to generate a "sunburst" from the right edge of the circle instead of a ring. It's an amusing effect but definitely not what I want. Other results included the circle looking exactly the same as the quad textured (aka drawing a sprite literally) or something that looked like a pop-art filter, by working on this train of thought. Seems like my logic here is entirely flawed, so, what would be the easiest way to obtain such a ring? No need to reply in code, just some guidance for a non-math-skilled user...

  • HP QTP 10: Web-app testing - SomeObj.FireEvent("OnCLick") works, SomeObj.Object.FireEvent("OnCLick") doesn't

    - by Vitaliy
    Hi all! I have rich web app btuil with ExtJS. It has multi-select list control (created with JS+CSS). I want to click on some item in that list using HP QuickTest Pro 10 with Internet Explorer 6. I added that item into Object repository and found that following code works - selects some item: Browser("blah").Page("blah").WebElement("SomeElem").Click next code also works: Browser("blah").Page("blah").WebElement("SomeElem").FireEvent("onMouseDown") Browser("blah").Page("blah").WebElement("SomeElem").FireEvent("onMouseUp") Browser("blah").Page("blah").WebElement("SomeElem").FireEvent("onClick") But I want to select several items using shift+click method. I don't know to do that :( So I have a few questions: How can perform click with mouse on several web elements with Shift key pressed? I tried to do that using CreateEventObject + shiftKey set to true, but the method (perform fireEvent on DOM object, not object from Object repository) doesn't work: Browser("blah").Page("blah").WebElement("SomeElem").Object.FireEvent("onClick") What the difference between WebElement("Element").FireEvent("OnClick") and WebElement("Element").Object.FireEvent("OnClick") ? Plsease, help someone, because I fought with that problem a lot, but had no result. Thanks!

  • Fulltext search on many tables

    - by Rob
    I have three tables, all of which have a column with a fulltext index. The user will enter search terms into a single text box, and then all three tables will be searched. This is better explained with an example: documents doc_id name FULLTEXT table2 id doc_id a_field FULLTEXT table3 id doc_id another_field FULLTEXT (I realise this looks stupid but that's because I've removed all the other fields and tables to simplify it). So basically I want to do a fulltext search on name, a_field and another_field, and then show the results as a list of documents, preferably with what caused that document to be found, e.g. if another_field matched, I would display what another_field is. I began working on a system whereby three fulltext search queries are performed and the results inserted into a table with a structure like: search_results table_name row_id score (This could later be made to cache results for a few days with e.g. a hash of the search terms). This idea has two problems. The first is that the same document can be in the search results up to three times with different scores. Instead of that, if the search term is matched in two tables, it should have one result, but a higher score. The second is that parsing the results is difficult. I want to display a list of documents, but I don't immediately know the doc_id without a join of some kind; however the table to join to is dependant on the table_name column, and I'm not sure how to accomplish that. Wanting to search multiple related tables like this must be a common thing, so I guess what I'm asking is am I approaching this in the right way? Can someone tell me the best way of doing it please.

  • Maintain denormalized data with NHibernate EventListener

    - by Michael Valenty
    I have one bit of denormalized data used for performance reasons and I'm trying to maintain the data with an NHibernate event listener rather than a trigger. I'm not convinced this is the best approach, but I'm neck deep into it and I want to figure this out before moving on. I'm getting following error: System.InvalidOperationException : Collection was modified; enumeration operation may not execute. System.ThrowHelper.ThrowInvalidOperationException(ExceptionResource resource) System.Collections.Generic.List`1.Enumerator.MoveNextRare() System.Collections.Generic.List`1.Enumerator.MoveNext() NHibernate.Engine.ActionQueue.ExecuteActions(IList list) NHibernate.Engine.ActionQueue.ExecuteActions() NHibernate.Event.Default.AbstractFlushingEventListener.PerformExecutions (IEventSource session) NHibernate.Event.Default.DefaultFlushEventListener.OnFlush(FlushEvent event) NHibernate.Impl.SessionImpl.Flush() NHibernate.Transaction.AdoTransaction.Commit() Here's the code to make happen: using (var tx = session.BeginTransaction()) { var business = session .Get<Business>(1234) .ChangeZipCodeTo("92011"); session.Update(business); tx.Commit(); // error happens here } and the event listener: public void OnPostUpdate(PostUpdateEvent @event) { var business = @event.Entity as Business; if (business != null) { var links = @event.Session .CreateQuery("select l from BusinessCategoryLink as l where l.Business.BusinessId = :businessId") .SetParameter("businessId", business.BusinessId) .List<BusinessCategoryLink>(); foreach (var link in links) { link.Location = business.Location; @event.Session.Update(link); } } }
