  • loading child swf as3

    - by RichW
    Hi, I've been given an fla to make some changes too. Basically its a fairly long timeline animation with sound. So far I've successfully added a few button functions for sound etc.. but one has got me stumped. One of the buttons needs to load a child swf. I'm using the code below but I'm recieving an error - 'Error #1009: Cannot access a property or method of a null object reference'. I believe this may be refferring to an object that isn't set yet but I have no idea which one it is: Code: var mcExt:MovieClip = new MovieClip(); var ldr:Loader = new Loader(); ldr.contentLoaderInfo.addEventListener(Event.COMPLETE, swfLoaded); ldr.load(new URLRequest("Downloads.swf")); function swfLoaded(e:Event):void { mcExt = MovieClip(ldr.contentLoaderInfo.content); ldr.contentLoaderInfo.removeEventListener(Event.COMPLETE, swfLoaded); mcExt.x = 50; mcExt.y = 50; addChild(mcExt); } Any help on what is going wrong would be greatly appreciated! Thanks

  • How does one convert from a Java resultset to ColdFusion query in Railo?

    - by Shawn Grigson
    The following works fine in CFMX 7 and CF8, and I'd assume CF9 as well: <!--- 'conn' is a JDBC connection ---> <cfset stat = conn.createStatement() /> <cfset rs = stat.executeQuery(trim(arguments.sql)) /> <!--- convert this Java resultset to a CF query recordset ---> <cfset queryTable = CreateObject("java", "coldfusion.sql.QueryTable")> <cfset queryTable.init(rs) > <cfset query = queryTable.FirstTable() /> This creates a statement using a JDBC driver, executes a query against it, putting it into a java resultset, and then coldfusion.sql.QueryTable is instantiated, passed the Java resulset object, and then queryTable.FirstTable() is called, which returns an actual coldfusion resultset (for cfloop and the like). The problem comes with a difference in Railo's implementation. Running this code in Railo returns the following error: No matching Constructor for coldfusion.sql.QueryTable(org.sqlite.RS) found. I've dumped the Railo java object, and don't see init() among the methods. Am I missing something simple? I'd love to get this working in Railo as well. Please note: I am doing a DSN-less connection to a SQLite db. I understand how to set up a CF datasource. My only hiccup at this point is doing the translation from a Java result set to a Railo query.

  • C#: Why am I still getting an RCW error when exiting my application?

    - by shifuimam
    To be specific, the error is: An attempt has been made to free an RCW that is in use. The RCW is in use on the active thread or another thread. Attempting to free an in-use RCW can cause corruption or data loss. The application in question is a small applet that displays the current clock speed of the CPU as a system tray icon. I'm using a System.Timers.Timer object to refresh the systray icon at an interval of 2.5 seconds. There's a single context menu item to exit the application, which uses the following function to unload everything: public void ExitApp(object sender, EventArgs e) { //stop and disable the timer theInterval.Stop(); theInterval.Enabled = false; //unload the system tray icon TheIcon.Visible = false; //exit the application Application.Exit(); } If I take out everything but Application.Exit(); I get an RCW error and the systray icon doesn't go away until I mouse over it. Everything was working perfectly until I changed the window style of the hidden form used to initialize the systray icon and the timer. If it helps any, I'm using C# 2010 Express.

  • Problem with SQLite related nUnit-tests after upgrade to VS2010 and Re#5

    - by stiank81
    After converting to Visual Studio 2010 with ReSharper5 some of my unit tests started failing. More specifically this applies to all unit tests that use NHibernate with SQLite. The problem seem to be related to SQLite somehow. The unit tests that does not involve NHibernate and SQLite are still running fine. The exception is as follows: NHibernate.HibernateException : Could not create the driver from NHibernate.Driver.SQLite20Driver, NHibernate, Version=2.1.2.4000, Culture=neutral, PublicKeyToken=aa95f207798dfdb4. ----> System.Reflection.TargetInvocationException : Exception has been thrown by the target of an invocation. ----> NHibernate.HibernateException : The IDbCommand and IDbConnection implementation in the assembly System.Data.SQLite could not be found. Ensure that the assembly System.Data.SQLite is located in the application directory or in the Global Assembly Cache. If the assembly is in the GAC, use <qualifyAssembly/> element in the application configuration file to specify the full name of the assembly. TearDown : System.NullReferenceException : Object reference not set to an instance of an object. The exception is the NullReferenceException on TearDown when cleaning up NHibernate objects that wasn't successfully created, but the problem seem to be related to SQLite somehow. I run my unit tests through ReSharper, but I get the same exception when running them directly through the NUnit.exe application. However, running them through the x86 variant (NUnit-x86.exe) all tests run fine. Can it be related to some mixing of 64bit and 32bit dlls? It still runs fine through VS2008 + ReSharper4.5. Note that the target framework of my projects still is .NET3.5. Anyone seen this problem before?

  • Web Workers - Transferable Objects for JSON

    - by kclem06
    HTML 5 Web workers are very slow when using worker.postMessage on a large JSON object. I'm trying to figure out how to transfer a JSON Object to a web worker - using the 'Transferable Objects' types in Chrome, in order to increase the speed of this. Here is what I'm referring to and appears it should speed this up quite a bit: http://updates.html5rocks.com/2011/12/Transferable-Objects-Lightning-Fast I'm having trouble finding a good example of this (and I don't believe I want to use an ArrayBuffer). Any help would be appreciated. I'm imagining something like this: worker = new Worker('workers.js'); var large_json = {}; for(var i = 0; i < 20000; ++i){ large_json[i] = i; large_json["test" + i] = "string"; }; //How to make this call to use Transfer Objects? Takes approx 2 seconds to serialize this for me currently. worker.webkitPostMessage(large_json);

  • StringTokenizer split at "<br/>"

    Maybe I am stupid but I don't understand why the behaviour of StringTokenizer here: import static org.apache.commons.lang.StringEscapeUtils.escapeHtml; String object = (String) value; String escaped = escapeHtml(object); StringTokenizer tokenizer = new StringTokenizer(escaped, escapeHtml("<br/>")); If fx. value is Hej<br/>$user.get(0).name Har vundet<br/><table border='1'><tr><th>Name</th><th>Played</th><th>Brewed</th></tr>#foreach( $u in $user )<tr><td>$u.name</td> <td>$u.played</td> <td>$u.brewed</td></tr>#end</table><br/> Then the result is Hej $use . e (0).name Ha vunde a e o de ='1' h Name h h P ayed h h B ewed h #fo each( $u in $use ) d $u.name d d $u.p ayed d d $u. ewed d #end a e It makes no sense to me. How can I make it behave as I expect to.

  • Android Hashtable Serialization

    - by Nsyed
    Hi All, I am having a weird issue with serialization of a Hashtable. I have made a Server, Client app. Where server(PC/MAC) is serializing a Hashtable and sending it to Client(Android) through UDP. The data is sent/read correctly but I get a bunch of these messages below on LogCat. 04-12 11:19:43.059: DEBUG/dalvikvm(407): GetFieldID: unable to find field Ljava/util/Hashtable;.loadFactor:F Occasionally, I would see these 04-12 11:21:19.150: DEBUG/dalvikvm(407): GC freed 10814 objects / 447184 bytes in 97ms The app would run for 2-3 mins and then crash. Interestingly enough I do not see the Loadfactor errors on SDK 1.5. But I do see the GC Free xxxx objects, quiet often. After debugging I have found that the issue is with de-serialization and the error/warning are coming from following code Code: ByteArrayInputStream bis = new ByteArrayInputStream(bytes); ObjectInputStream ois = new ObjectInputStream(bis); object = ois.readObject(); at Code: object = ois.readObject(); on the client. My server is serializing code is the following. Code: ByteArrayOutputStream bos = new ByteArrayOutputStream(); ObjectOutputStream oos = new ObjectOutputStream(bos); oos.writeObject(obj); Any idea what is going on? Thanks for the Help!

  • Need some help/advice on WCF Per-Call Service and NServiceBus interop.

    - by Alexey
    I have WCF Per-Call service wich provides data for clients and at the same time is integrated with NServiceBus. All statefull objects are stored in UnityContainer wich is integrated into custom service host. NServiceBus is configured in service host and uses same container as service instances. Every client has its own instance context(described by Juval Lowy in his book in chapter about Durable Services). If i need to send request over bus I just use some kind of dispatcher and wait response using Thread.Sleep().Since services are per-call this is ok afaik. But I am confused a bit about messages from bus, that service must handle and provide them to clients. For some data like stock quotes I just update some kind of statefull object and and then, when clients invoke GetQuotesData() just provide data from this object. But there are numerous service messages like new quote added and etc. At this moment I have an idea to implement something like "Postman daemon" =)) and store this type of messages in instance context. Then client will invoke "GetMail()",recieve those messages and parse them. Problem is that NServiceBus messages are "Interface based" and I cant pass them over WCF, so I need to convert them to types derieved from some abstract class. Dunno what is best way to handle this situation. Will be very gratefull for any advice on this. Thanks in advance.

  • Getting the first result from a LINQ query - why does ElementAt<T>(0) fails when First<T>() succeeds

    - by Mr Roys
    I have a method AddStudent() which looks for a student with the same name and returns an existing student from the database if there is a student with the same name, otherwise it creates a new student and adds it to the database. I'm curious why se = students.First<StudentEntity>(); succeeds when se = students.ElementAt<StudentEntity>(0); fails when I try to get the first result from the LINQ query. Aren't the two methods the same? The full code for the method is shown below. public Student AddStudent(string name) { using (SchoolEntities db = new SchoolEntities()) { // find student with same name via LINQ var students = from s in db.StudentEntitySet where s.name == name select s; StudentEntity se = default(StudentEntity); // if student with the same name is already present, return // that student if (students.Count<StudentEntity>() > 0) { // if i use ElementAt, if fails with a "LINQ to Entities does not // recognize the method 'StudentEntity ElementAt[StudentEntity] // (System.Linq.IQueryable`1[StudentEntity], Int32)' method, // and this method cannot be translated into a store expression.", // but not when I use First. Why? // se = students.ElementAt<StudentEntity>(0); se = students.First<StudentEntity>(); } else { // passing 0 for first parameter (id) since it's represented by // a BigInt IDENTITY field in the database so any value // doesn't matter. se = StudentEntity.CreateStudentEntity(0, name); db.AddToStudentEntitySet(se); db.SaveChanges(); } // create a Student object from the Entity object return new Student(se); } } Thanks!

  • How to make a Global Array?

    - by Wayfarer
    So, I read this post, and it's pretty much exactly what I was looking for. However... it doesn't work. I guess I'm not going to go with the singleton object, but rather making the array in either a Global.h file, or insert it into the _Prefix file. Both times I do that though, I get the error: Expected specifier-qualifier-list before 'static' and it doesn't work. So... I'm not sure how to get it to work, I can remove extern and it works, but I feel like I need that to make it a constant. The end goal is to have this Mutable Array be accessible from any object or any file in my project. Help would be appreciated! This is the code for my Globals.h file: #import <Foundation/Foundation.h> @interface Globals : NSObject { static extern NSMutableArray * myGlobalArray; } @end I don't think I need anything in the implementation file. If I were to put that in the prefix file, the error was the same.

  • How to avoid serializing zero values with Simple Xml

    - by Bram Vandenbussche
    I'm trying to serialise an object using simple xml (http://simple.sourceforge.net/). The object setup is pretty simple: @Root(name = "order_history") public class OrderHistory { @Element(name = "id", required = false) public int ID; @Element(name = "id_order_state") public int StateID; @Element(name = "id_order") public int OrderID; } The problem is when I create a new instance of this class without an ID: OrderHistory newhistory = new OrderHistory(); newhistory.OrderID = _orderid; newhistory.StateID = _stateid; and I serialize it via simple xml: StringWriter xml = new StringWriter(); Serializer serializer = new Persister(); serializer.write(newhistory, xml); it still reads 0 in the resulting xml: <?xml version='1.0' encoding='UTF-8'?> <order_history> <id>0</id> <id_order>2</id_order> <id_order_state>8</id_order_state> </order_history> I'm guessing the reason for this is that the ID property is not null, since integers can't be null. But I really need to get rid of this node, and I'd rather not remove it manually. Any clues anyone?

  • How to solve concurrency problems in ASP.NET Windows-Workflow and ActiveRecord/NHibernate?

    - by Famous Nerd
    I have found that ActiveRecord uses the Session-Scope object within the ASP.NET application and that if the web-site is read-write we can have a tug-o-war between the Workflow's own Data-Access SessionScope and that of the ASP.NET site. I would really like to have the WindowsWorkflow Runtime use the same object session as the web-site however, they have different lifetimes. Sometimes, a web-request may save a very simple piece of data which would execute quickly however, if the web-site kicks off a workflow process.. how can that workflow make data-modifications while still allowing the Appliaction_EndRequest to dispose the ASP.NET SessionScope ... it's like ownership of the SessionScope should be shared between the workflow runtime and the ASP.NET website. Manual Workflow Scheduler may be the Savior... if a workflow is synchronous and merely uses CallExternalMethod to interact with the Host then we could constrain all the data-access to the host.. then the sessionScope can exist once. This however, won't solve the problem of a delay activity... if this delay fires, we could need to update data... in this case we'd need an isolated Session Scope and concurrency may arise. This however, differs from SharePoint workflows where it seems that the SharePoint workflow can save data from the web and the workflow and that concurrency is handled through other means. Can anyone offer any suggestions on how to allow the workflow to manage data and play nice with ASP.NET web sites?

  • JAXB does not call setter when unmarshalling objects

    - by Yaneeve
    Hi all, I am using JAXB 2.0 JDK 6 in order to unmarshall an XML instance into POJOs. In order to add some custom validation I have inserted a validation call into the setter of a property, yet despite it being private, it seems that the unmarshaller does not call the setter but directly modifies the private field. It is crucial to me that the custom validation occurs for this specific field every unmarshall call. What should I do? Code: @XmlAccessorType(XmlAccessType.FIELD) @XmlType(name = "LegalParams", propOrder = { "value" }) public class LegalParams { private static final Logger LOG = Logger.getLogger(LegalParams.class); @XmlTransient private LegalParamsValidator legalParamValidator; public LegalParams() { try { WebApplicationContext webApplicationContext = ContextLoader.getCurrentWebApplicationContext(); LegalParamsFactory legalParamsFactory = (LegalParamsFactory) webApplicationContext.getBean("legalParamsFactory"); HttpSession httpSession = SessionHolder.getInstance().get(); legalParamValidator = legalParamsFactory.newLegalParamsValidator(httpSession); } catch (LegalParamsException lpe) { LOG.warn("Validator related error occurred while attempting to construct a new instance of LegalParams"); throw new IllegalStateException("LegalParams creation failure", lpe); } catch (Exception e) { LOG.warn("Spring related error occurred while attempting to construct a new instance of LegalParams"); throw new IllegalStateException("LegalParams creation failure", e); } } @XmlValue private String value; /** * Gets the value of the value property. * * @return * possible object is * {@link String } * */ public String getValue() { return value; } /** * Sets the value of the value property. * * @param value * allowed object is * {@link String } * @throws TestCaseValidationException * */ public void setValue(String value) throws TestCaseValidationException { legalParamValidator.assertValid(value); this.value = value; } }

  • SqlLite/Fluent NHibernate integration test harness initialization not repeatable after large data se

    - by Mark Rogers
    In one of my main data integration test harnesses I create and use Fluent NHibernate's SingleConnectionSessionSourceForSQLiteInMemoryTesting, to get a fresh session for each test. After each test, I close the connection, session, and session factory, and throw out the nested StructureMap container they came from. This works for almost any simple data integration test I can think, including ones that utilize Fluent NHib's PersistenceSpecification object. When I test the application's lengthy database bootstrapping process, which creates and saves thousands of domain objects, I start seeing issues. It's not that the setup and tear down fails, in fact, the test successfully bootstraps the in-memory database as the application would bootstrap the real database in the production environment. The problem occurs when the database bootstrapping occurs a second time on a new in-memory database, with a new session and session factory. The error is: NHibernate.StaleStateException : Unexpected row count: 0; expected: 1 The row count is indeed Unexpected, the row that the application under test is looking for should be in the session. You see, it's not that any data from the last integration test is sticking around, it's that for some reason the session just stops working mid-database-boostrap. And I've looked everywhere for a place I might be holding on to an old session and I can't find one. I've searched through the code for static singleton objects, but there are none anywhere near the code in question. I have a couple StructureMap InstanceScope singleton's but they are getting thrown out with each nested container that is lost after every test teardown. I've tried every possible variation on disposing and closing every object involved with each test teardown and it still fails on this lengthy database bootstrap. But non-bootstrap related database tests appear to work fine. I'm starting to run out of options and may have to surrender lengthy database integration tests in favor of WatiN-based acceptance tests. Can anyone give me any clue about how I can figure out why some of my SingleConnectionSessionSourceForSQLiteInMemoryTesting aren't repeatable? Any advice at all, about how to make an NHibernate SqlLite database integration test harness repeatable?

  • Invert linear linked list

    - by ArtWorkAD
    Hi, a linear linked list is a set of nodes. This is how a node is defined (to keep it easy we do not distinguish between node an list): class Node{ Object data; Node link; public Node(Object pData, Node pLink){ this.data = pData; this.link = pLink; } public String toString(){ if(this.link != null){ return this.data.toString() + this.link.toString(); }else{ return this.data.toString() ; } } public void inc(){ this.data = new Integer((Integer)this.data + 1); } public void lappend(Node list){ Node child = this.link; while(child != null){ child = child.link; } child.link = list; } public Node copy(){ if(this.link != null){ return new Node(new Integer((Integer)this.data), this.link.copy()); }else{ return new Node(new Integer((Integer)this.data), null); } } public Node invert(){ Node child = this.link; while(child != null){ child = child.link; } child.link = this;.... } } I am able to make a deep copy of the list. Now I want to invert the list so that the first node is the last and the last the first. The inverted list has to be a deep copy. I started developing the invert function but I am not sure. Any Ideas? Update: Maybe there is a recursive way since the linear linked list is a recursive data structure. I would take the first element, iterate through the list until I get to a node that has no child and append the first element, I would repeat this for the second, third....

  • iPhone: contentInset isn't animating

    - by Cuzog
    In my app, I have a table view. When the user clicks a button, a UIView overlays part of that table view. It's essentially a partial modal. That table view is intentionally still scrollable while that modal is active. To allow the user to scroll to the bottom of the table view, I change the contentInset and scrollIndicatorInsets values to adjust for the smaller area above the modal. When the modal is taken away, I reset those inset values. The problem is that when the user has scrolled to the bottom of the newly adjusted inset and then dismisses the modal, the table view jumps abruptly to a new scroll position because the inset is changed instantly. I would like to animate it so there is a transition, but the beginAnimation/commitAnimations methods aren't affecting it for some reason. Any ideas as to why the values aren't getting animated? Any help is greatly appreciated! The relevant code from the table view controller is here: - (void)viewDidLoad { [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(modalOpened) name:@"ModalStartedOpening" object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(modalDismissed) name:@"ModalStartedClosing" object:nil]; [super viewDidLoad]; } - (void)modalOpened { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.5]; [UIView setAnimationDelegate:self]; self.tableView.contentInset = UIEdgeInsetsMake(0, 0, 201, 0); self.tableView.scrollIndicatorInsets = UIEdgeInsetsMake(0, 0, 201, 0); [UIView commitAnimations]; } - (void)modalDismissed { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.5]; [UIView setAnimationDelegate:self]; self.tableView.contentInset = UIEdgeInsetsMake(0, 0, 0, 0); self.tableView.scrollIndicatorInsets = UIEdgeInsetsMake(0, 0, 0, 0); [UIView commitAnimations]; }

  • NHibernate: Mapping multiple classes from a single table row

    - by Michael Kurtz
    I couldn't find an answer to this specific question. I am trying to keep my domain model object-oriented and re-use objects where possible. I am having an issue determining how to provide a mapping to multiple classes from a single row. Let me explain with an example: I have a single table, call it Customer. A customer has several attributes; but, for brevity, assume it has Id, Name, Address, City, State, ZipCode. I would like to create a Customer and Address class that look like this: public class Customer { public virtual long Id {get;set;} public virtual string Name {get;set;} public virtual Address Address {get;set;} } public class Address { public virtual string Address {get;set;} public virtual string City {get;set;} public virtual string State {get;set;} public virtual string ZipCode {get;set;} } What I am having trouble with is determining what the mapping would be for the Address class within the Customer class. There is no Address table and there isn't a "set" of addresses associated with a Customer. I just want a more object-oriented view of the Customer table in code. There are several other tables that have address information in them and it would be nice to have a reusable Address class to deal with them. Addresses are not shared so breaking all addresses into a separate table with foreign keys seems to be overkill and, actually, more painful since I would need foreign keys to multiple tables. Can someone enlighten me on this type of mapping? Please provide an example if you can. Thanks for any insights! -Mike

  • log4js ConsoleAppender initialization

    - by perrierism
    I'm wondering if anyone happens to have some experience using Log4js? It seems its normal ConsoleAppender isn't always ready to use immediately after it's added to a logger object... If I have two sequential script tags in a document like: //Initialize logger <script type="text/javascript"> var logger = new Log4js.getLogger("JSLOG"); logger.addAppender(new Log4js.ConsoleAppender(logger, false)); logger.setLevel(Log4js.Level.INFO); </script> //Use logger <script type="text/javascript"> logger.info('Test test'); </script> ... It causes the console pop-up (pop-up window) to appear with an error message on page load: 12:58:23 PM WARN Log4js - Could not run the listener function () { return fn.apply(object, arguments); }. TypeError: this.outputElement is null The console is still initialised, it's there afterward, but for just that first logger call it doesn't seem to be there fully. If I make the first logger call setTimeout("logger.info('test test')", 1000), it doesn't have the error. So it's like it's not ready immediately. Anyone see this before or know what a workaround might be? Cheers

  • Save QList<int> to QSettings

    - by Tobias
    Hello, I want to save a QList<int> to my QSettings without looping through it. I know that I could use writeArray() and a loop to save all items or to write the QList to a QByteArray and save this but then it is not human readable in my INI file.. Currently I am using the following to transform my QList<int> to QList<QVariant>: QList<QVariant> variantList; //Temp is the QList<int> for (int i = 0; i < temp.size(); i++) variantList.append(temp.at(i)); And to save this QList<Variant> to my Settings I use the following code: QVariant list; list.setValue(variantList); //saveSession is my QSettings object saveSession.setValue("MyList", list); The QList is correctly saved to my INI file as I can see (comma seperated list of my ints) But the function crashes on exit. I already tried to use a pointer to my QSettings object instead but then it crashes on deleting the pointer ..

  • Ajax model binding of a complex type

    - by David G
    I am trying to do something along the lines of the following where I have a Controller with an method similar to: public ActionResult Insert(Author author) { //do something... } Where the Author type looks like: public class Author { public string FirstName { get; set; } public string LastName { get; set; } public Book[] Books { get; set; } public Author() { Books = new Book[0]; } } public class Book { public string Title { get; set; } public int NumberOfPages { get; set; } } From a page I want to submit data using JQuery and Ajax something like function addAuthor() { var auth = { 'FirstName': 'Roald', 'LastName': 'Dahl', 'Books': [ { 'Title': 'Charlie and the Chocolate Factory', 'NumberOfPages': 264 }, { 'Title': 'The Twits', 'NumberOfPages': 316 } ] }; $.ajax({ type: "GET", url: "/Insert", data: auth }); } MVC binds the Author object (FirstName and LastName are set) but doesn't bind the Books property. Why is that and how can I submit an object containing an Array (or a Collection) as a property through AJAX?

  • Is there any way to combine transparency and "ajax usability" with HTML templates

    - by Sam
    I'm using HTML_Template_Flexy in PHP but the question should apply to any language or template library. I am outputting a list of relatively complex objects. In the beginning I just iterated over a list of the objects and called a toHtml method on them. When I was about to have my layout designer look over the template I noticed that it was too opaque and that he would have ended up looking through and/or editing many additional php source files to see what really gets generated by the toHtml method. So I extracted most of the HTML strings in the php classes up to the template which made for one clear file where you can see the whole page structure at once. However this causes problems when you want to add an object to the list using javascript. Then I have to keep the old toHtml method and maintain both the main template and the html strings at the same time, so I can output just the HTML for a new object that should be added to the page. So I'm back to the idea of using smaller templates for the objects that make up the page, but I was wondering if there was some easy way of having my cake and eating it too by having one template that shows the whole page but also the mini-templates for smaller objects on the page. Edit: Yes, updating the page is not a problem at all. My concern is with having both maintainability and transparency of the template files. If I have one single template for the whole page, then I must maintain mini-templates of the objects that are shown on the page. If I just have the mini-templates and include them from the higher-level template it becomes more difficult to look at the top-level html and imagine what the end result will look like.

  • VB .Net - Reflection: Reflected Method from a loaded Assembly executes before calling method. Why?

    - by pu.griffin
    When I am loading an Assembly dynamically, then calling a method from it, I appear to be getting the method from Assembly executing before the code in the method that is calling it. It does not appear to be executing in a Serial manner as I would expect. Can anyone shine some light on why this might be happening. Below is some code to illustrate what I am seeing, the code from the some.dll assembly calls a method named PerformLookup. For testing I put a similar MessageBox type output with "PerformLookup Time: " as the text. What I end up seeing is: First: "PerformLookup Time: 40:842" Second: "initIndex Time: 45:873" Imports System Imports System.Data Imports System.IO Imports Microsoft.VisualBasic.Strings Imports System.Reflection Public Class Class1 Public Function initIndex(indexTable as System.Collections.Hashtable) As System.Data.DataSet Dim writeCode As String MessageBox.Show("initIndex Time: " & Date.Now.Second.ToString() & ":" & Date.Now.Millisecond.ToString()) System.Threading.Thread.Sleep(5000) writeCode = RefreshList() End Function Public Function RefreshList() As String Dim asm As System.Reflection.Assembly Dim t As Type() Dim ty As Type Dim m As MethodInfo() Dim mm As MethodInfo Dim retString as String retString = "" Try asm = System.Reflection.Assembly.LoadFrom("C:\Program Files\some.dll") t = asm.GetTypes() ty = asm.GetType(t(28).FullName) 'known class location m = ty.GetMethods() mm = ty.GetMethod("PerformLookup") Dim o as Object o = Activator.CreateInstance(ty) Dim oo as Object() retString = mm.Invoke(o,Nothing).ToString() Catch Ex As Exception End Try return retString End Function End Class
