  • Cache of Objects or OutPut in View ? Wich is better ?

    - by Felipe
    Hi everybody, I have an ecommerce working in ASP.Net MVC. i'm using Caching to improve more performace in my pages and it's working fine. I'd link to know what is more performative, for example, I can set OutPutCache in my views and and use this cache for all page OR I could get my List of Products in controller, put it on cache (like the code below) and send it to View to render for the user??? private IEnumerable<Products> GetProductsCache(string key, ProductType type) { if (HttpContext.Cache[key] == null) HttpContext.Cache.Insert(key, ProductRepository.GetProducts(type), null, DateTime.Now.AddMinutes(10), Cache.NoSlidingExpiration); return (IEnumerable<Products>)HttpContext.Cache[key]; } public ActionResult Index() { var home = new HomeViewModel() { Products = GetProductsCache("ProductHomeCache", ProductType.Product) Services = GetProductsCache("ServiceHomeCache", ProductType.Service) }; return View(home); } Both works fine, but I'd like to know what is suggested to improve more performace ? Or is there others way to do it better ? PS: sorry for my english! thanks all... Cheers

  • MSCRM 4 Convert Standard enitity to Custom entity using InitializeFromRequest

    - by user363727
    Hi there, I'm trying to convert an order and orderdetail lines to a custom entity and its child lines using InitializeFromRequest using the code below: public void Convert(Guid FromEntityId, string FromEntityName, string ToEntityName) { try { // Set up the CRM Service. CrmService _service = GetCrmService(); InitializeFromRequest req = new InitializeFromRequest(); req.EntityMoniker = new Moniker(); // this is the very thing that does the job. req.EntityMoniker.Id = FromEntityId; req.EntityMoniker.Name = FromEntityName; req.TargetEntityName = ToEntityName; //contact for our example req. req.TargetFieldType = TargetFieldType.ValidForCreate; InitializeFromResponse rps = (InitializeFromResponse)_service.Execute(req); //now the lead is converted to a contact, and you can see it in contacts. Guid entityId = _service.Create(rps.Entity); lblMsg.Text = "Done ID:" + entityId.ToString(); } catch (System.Web.Services.Protocols.SoapException se) { lblMsg.Text = "soap:" + se.Detail.InnerText; } catch (Exception ex) { lblMsg.Text = ex.Message; } } Now i am able to get a custom entity created but all the attributes are empty despite me setting the mapping fields in the realtionship. Any ideas on what i am missing or doing wrong? Thanks in advance Andrew

  • Is C# slower than VB.NET?

    - by Matt Winckler
    Believe it or not, despite the title, this is not a troll. Running some benchmarks this morning, my colleagues and I have discovered some strange things concerning performance, and I am wondering if we're doing something horribly wrong. We started out comparing C# vs. Delphi Prism calculating prime numbers, and found that Prism was about 30% faster. I figured maybe CodeGear did more optimization when generating IL (the exe was about twice as big as C#'s and had all sorts of different IL in it.) So I decided to write a test in VB.NET as well, assuming that Microsoft's compilers would end up writing essentially the same IL for each language. However, the result there was more shocking: C# was more than three times slower than VB running the same operations. The generated IL was different, but not extremely so, and I'm not good enough at reading it to understand the differences. As a fan of C#, this apparent slowness wounds me horribly, and I am left wondering: what in the world is going on here? Is it time to pack it all in and go write web apps in Ruby? ;-) I've included the code for each below--just copy it into a new VB or C# console app, and run. On my machine, VB finds 348513 primes in about 6.36 seconds. C# finds the same number of primes in 21.76 seconds. (I've got an Intel Core2 Quad Q6600 @2.4Ghz; on another Intel machine in the office the code for both runs much faster but the ratio is about the same; on an AMD machine here the timing is ~10 seconds for VB and ~13 for C#--much less difference, but C# is still always slower.) Both of the console applications were compiled in Release mode, but otherwise no project settings were changed from the defaults generated by Visual Studio 2008. Is it a generally-known fact that C#'s generated IL is worse than VB's? Or is this a strange edge case? Or is my code flawed somehow (most likely)? Any insights are appreciated. VB code Imports System.Diagnostics Module Module1 Private temp As List(Of Int32) Private sw As Stopwatch Private totalSeconds As Double Sub Main() serialCalc() End Sub Private Sub serialCalc() temp = New List(Of Int32)() sw = Stopwatch.StartNew() For i As Int32 = 2 To 5000000 testIfPrimeSerial(i) Next sw.Stop() totalSeconds = sw.Elapsed.TotalSeconds Console.WriteLine(String.Format("{0} seconds elapsed.", totalSeconds)) Console.WriteLine(String.Format("{0} primes found.", temp.Count)) Console.ReadKey() End Sub Private Sub testIfPrimeSerial(ByVal suspectPrime As Int32) For i As Int32 = 2 To Math.Sqrt(suspectPrime) If (suspectPrime Mod i = 0) Then Exit Sub End If Next temp.Add(suspectPrime) End Sub End Module C# Code using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Diagnostics; namespace FindPrimesCSharp { class Program { List<Int32> temp = new List<Int32>(); Stopwatch sw; double totalSeconds; static void Main(string[] args) { new Program().serialCalc(); } private void serialCalc() { temp = new List<Int32>(); sw = Stopwatch.StartNew(); for (Int32 i = 2; i <= 5000000; i++) { testIfPrimeSerial(i); } sw.Stop(); totalSeconds = sw.Elapsed.TotalSeconds; Console.WriteLine(string.Format("{0} seconds elapsed.", totalSeconds)); Console.WriteLine(string.Format("{0} primes found.", temp.Count)); Console.ReadKey(); } private void testIfPrimeSerial(Int32 suspectPrime) { for (Int32 i = 2; i <= Math.Sqrt(suspectPrime); i++) { if (suspectPrime % i == 0) return; } temp.Add(suspectPrime); } } }

  • Should the entity framework + self tracking entities be saving me time

    - by sipwiz
    I've been using the entity framework in combination with the self tracking entity code generation templates for my latest silverlight to WCF application. It's the first time I've used the entity framework in a real project and my hope was that I would save myself a lot of time and effort by being able to automatically update the whole data access layer of my project when my database schema changed. Happily I've found that to be the case, updating my database schema by adding a new table, changing column names, adding new columns etc. etc. can be propagated to my business object classes by using the update from database option on the entity framework model. Where I'm hurting is the CRUD operations within my WCF service in response to actions on my Silverlight client. I use the same self tracking entity framework business objects in my Silverlight app but I find I'm continually having to fight against problems such as foreign key associations not being handled correctly when updating an object or the change tracker getting confused about the state of an object at the Silverlight end and the data access operation within the WCF layer throwing a wobbly. It's got to a point where I have now spent more time dealing with this quirks than I have on my previous project where I used Linq-to-SQL as the starting point for rolling my own business objects. Is it just me being hopeless or is the self tracking entities approach something that should be avoided until it's more mature?

  • asp.Net 2005 "Could not load type"

    - by Melody Friedenthal
    Although I have seen dozens of forum questions relating to "Could not load type", none of the advice in them seemed to apply to my situation. I wrote a new web application using aspx.net VB 2005. It is tiny, with just 2 pages, 1 of which has no code-behind. It runs aok in the IDE but when I installed it on my pc (and also when installed on the production server), and tried to run it this error came up: Parser Error Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. Parser Error Message: Could not load type 'EMTTrainingDatabase.pageMain'.

  • Persistence classes in Qt

    - by zarzych
    Hi, I'm porting a medium-sized CRUD application from .Net to Qt and I'm looking for a pattern for creating persistence classes. In .Net I usually created abstract persistence class with basic methods (insert, update, delete, select) for example: public class DAOBase<T> { public T GetByPrimaryKey(object primaryKey) {...} public void DeleteByPrimaryKey(object primaryKey) {...} public List<T> GetByField(string fieldName, object value) {...} public void Insert(T dto) {...} public void Update(T dto) {...} } Then, I subclassed it for specific tables/DTOs and added attributes for DB table layout: [DBTable("note", "note_id", NpgsqlTypes.NpgsqlDbType.Integer)] [DbField("note_id", NpgsqlTypes.NpgsqlDbType.Integer, "NoteId")] [DbField("client_id", NpgsqlTypes.NpgsqlDbType.Integer, "ClientId")] [DbField("title", NpgsqlTypes.NpgsqlDbType.Text, "Title", "")] [DbField("body", NpgsqlTypes.NpgsqlDbType.Text, "Body", "")] [DbField("date_added", NpgsqlTypes.NpgsqlDbType.Date, "DateAdded")] class NoteDAO : DAOBase<NoteDTO> { } Thanks to .Net reflection system I was able to achieve heavy code reuse and easy creation of new ORMs. The simplest way to do this kind of stuff in Qt seems to be using model classes from QtSql module. Unfortunately, in my case they provide too abstract an interface. I need at least transactions support and control over individual commits which QSqlTableModel doesn't provide. Could you give me some hints about solving this problem using Qt or point me to some reference materials? Update: Based on Harald's clues I've implemented a solution that is quite similar to the .Net classes above. Now I have two classes. UniversalDAO that inherits QObject and deals with QObject DTOs using metatype system: class UniversalDAO : public QObject { Q_OBJECT public: UniversalDAO(QSqlDatabase dataBase, QObject *parent = 0); virtual ~UniversalDAO(); void insert(const QObject &dto); void update(const QObject &dto); void remove(const QObject &dto); void getByPrimaryKey(QObject &dto, const QVariant &key); }; And a generic SpecializedDAO that casts data obtained from UniversalDAO to appropriate type: template<class DTO> class SpecializedDAO { public: SpecializedDAO(UniversalDAO *universalDao) virtual ~SpecializedDAO() {} DTO defaultDto() const { return DTO; } void insert(DTO dto) { dao->insert(dto); } void update(DTO dto) { dao->update(dto); } void remove(DTO dto) { dao->remove(dto); } DTO getByPrimaryKey(const QVariant &key); }; Using the above, I declare the concrete DAO class as following: class ClientDAO : public QObject, public SpecializedDAO<ClientDTO> { Q_OBJECT public: ClientDAO(UniversalDAO *dao, QObject *parent = 0) : QObject(parent), SpecializedDAO<ClientDTO>(dao) {} }; From within ClientDAO I have to set some database information for UniversalDAO. That's where my implementation gets ugly because I do it like this: QMap<QString, QString> fieldMapper; fieldMapper["client_id"] = "clientId"; fieldMapper["name"] = "firstName"; /* ...all column <-> field pairs in here... */ dao->setFieldMapper(fieldMapper); dao->setTable("client"); dao->setPrimaryKey("client_id"); I do it in constructor so it's not visible at a first glance for someone browsing through the header. In .Net version it was easy to spot and understand. Do you have some ideas how I could make it better?

  • SQL Agent Logon - What is going on?

    - by James Wiseman
    I have a DTSX package that is called from a SQL Agent Job. The DTSX package references a file at a fixed location (e.g. e:\mssql\myfile.txt). On most machines, this location exists, but on some I have to manually map this (which is not a problem - I know a better solution would be to use package conifgurations to dynamically pull the file location, but this is not an option here - and anyway I'd like to understand what is going on) I have set up the agent service to run as a specific user (e.g. myuser) When I log on as this user and map the directory, then run the dtsx package directly, then all goes well. When I run the package through a SQL Agent Job, the file cannot be found. If I add a command line job step to the agent job to map the drive: net use e: \\svr\location Then all works file also. So what is going on in the backgound? How come the SQL Agent user requries the drive mapping even when I am logged in as this user.

  • LinqToSQL Double Insert issue

    - by Vaccano
    I have a WCF service with an object structure similar to this: public class MyClass { public List<MySubItem> SubItems { get; set; } } public class MySubItem { public List<MySubSubItem> SubSubItems { get; set; } } public class MySubSubItem { public string DataValue { get; set; } } public class MyClassDAL { public void InsertMyClass(MyClass myClass) { ctx.MyClasses.InsertOnSubmit(myClass); ctx.SubmitChanges(); } } Sometimes my client will call in with a MyClass that submits only half of the values that it has in the list SubSubItems. Later it calls the insert with the rest of the list. The problem is that when it does this I get a Primary Key violation. The reason is that it is trying to insert the MySubItem again (because there are more items in the SubSubItems owned by the same MySubItem object). How do I deal with this? Do I just call an Update? Do I have to try to separate them out (updates from inserts)? SQL Server 2008 has a really cool Merge functionally. Is there some way to access that from LinqToSQL?

  • Help me create a Firefox extension (Javascript XPCOM Component)

    - by Johnny Grass
    I've been looking at different tutorials and I know I'm close but I'm getting lost in implementation details because some of them are a little bit dated and a few things have changed since Firefox 3. I have already written the javascript for the firefox extension, now I need to make it into an XPCOM component. This is the functionality that I need: My Javascript file is simple, I have two functions startServer() and stopServer. I need to run startServer() when the browser starts and stopServer() when firefox quits. Edit: I've updated my code with a working solution (thanks to Neil). The following is in MyExtension/components/myextension.js. Components.utils.import("resource://gre/modules/XPCOMUtils.jsm"); const CI = Components.interfaces, CC = Components.classes, CR = Components.results; // class declaration function MyExtension() {} MyExtension.prototype = { classDescription: "My Firefox Extension", classID: Components.ID("{xxxx-xxxx-xxx-xxxxx}"), contractID: "@example.com/MyExtension;1", QueryInterface: XPCOMUtils.generateQI([CI.nsIObserver]), // add to category manager _xpcom_categories: [{ category: "profile-after-change" }], // start socket server startServer: function () { /* socket initialization code */ }, // stop socket server stopServer: function () { /* stop server */ }, observe: function(aSubject, aTopic, aData) { var obs = CC["@mozilla.org/observer-service;1"].getService(CI.nsIObserverService); switch (aTopic) { case "quit-application": this.stopServer(); obs.removeObserver(this, "quit-application"); break; case "profile-after-change": this.startServer(); obs.addObserver(this, "quit-application", false); break; default: throw Components.Exception("Unknown topic: " + aTopic); } } }; var components = [MyExtension]; function NSGetModule(compMgr, fileSpec) { return XPCOMUtils.generateModule(components); }

  • WCF Certificates without Certificate Store

    - by Kane
    My team is developing a number of WPF plug-ins for a 3rd party thick client application. The WPF plug-ins use WCF to consume web services published by a number of TIBCO services. The thick client application maintains a separate central data store and uses a proprietary API to access the data store. The thick client and WPF plug-ins are due to be deployed onto 10,000 workstations. Our customer wants to keep the certificate used by the thick client in the central data store so that they don't need to worry about re-issuing the certificate (current re-issue cycle takes about 3 months) and also have the opportunity to authorise the use of the certificate. The proposed architecture offers a form of shared secret / authentication between the central data store and the TIBCO services. Whilst I don’t necessarily agree with the proposed architecture our team is not able to change it and must work with what’s been provided. Basically our client wants us to build into our WPF plug-ins a mechanism which retrieves the certificate from the central data store (which will be allowed or denied based on roles in that data store) into memory then use the certificate for creating the SSL connection to the TIBCO services. No use of the local machine's certificate store is allowed and the in memory version is to be discarded at the end of each session. So the question is does anyone know if it is possible to pass an in-memory certificate to a WCF (.NET 3.5) service for SSL transport level encryption? Note: I had asked a similar question (here) but have since deleted it and re-asked it with more information.

  • Finding Common Phrases in SQL Server TEXT Column

    - by regex
    Short Desc: I'm curious to see if I can use SQL Analysis services or some other SQL Server service to mine some data for me that will show commonalities between SQL TEXT fields in a dataset. Long Desc I am looking at a subset of data that consists of about 10,000 rows of TEXT blobs which are used as a notes column in a issue tracking (ticketing) software. I would like to use something out of the box (without having to build something) that might be able to parse through all of the rows and find commonly used byte sequences in the "Notes" column. In other words, I want to find commonly used phrases (two to three word phrases, so 9 - 20 character sections of the TEXT blob). This will help me better determine if associate's notes contain similar phrases (troubleshooting techniques) that we could standardize in our troubleshooting process flow. Closing Note I'd really rather not build an application to do this as my method will probably not be the most efficient way to do it. Hopefully all this makes sense. Please let me know in the comments if anything needs clarification.

  • Attributes of attributevalue element in SAML 2 Attribute Statement

    - by AJ
    I am building a web service that receives a SAML attribute query and responds with an attribute statement. I know I can return one or multiple values of a SAML attribute. I have some values that are dependent on the other attribute values. I need to show that relationship. Let us say, the query is for the Subject Dave and the return values are his company and job title. Dave can work at multiple companies with job title at each company. I have two options of sending this data back: Send this as a complextype by defining an attribute organization and return xml within that attribute. <saml:Attribute name="company"> <saml:AttributeValue> <company name="company1" jobtitle="CIO"/> <company name="company2" jobtitle="VP"/> </saml:AttributeValue> Try to send multiple values of attributes somehow sending a reference in attributevalue element. <saml:Attribute name="company"> <attributeValue>company1</attributeValue> <attributeValue>company2</attributeValue> </saml:Attribute> <saml:Attribute name="jobTitle> <attributeValue company="company1">CIO</attributeValue> <attributeValue company="company2">VP</attributeValue> </saml:Attribute> Which approach will you prefer? Why? I am biased towards second approach as it does not require client to know about any schema. It does require them to know about non-standard attribute company in the attribute value.

  • Testing background audio in the simulator

    - by Cactuar
    I'm experimenting with the new background audio service in iPhone OS 4.0 but I can't get it to work in the simulator. According to this page: iPhone Application Programming Guide: Executing Code in the Background it seems that all I have to do is add the a UIBackgroundModes key with an array containing audio to my Info.plist file and the audio my application plays should automatically continue when I switch to another app. I have done this but the audio still pauses as I switch to another app, when I switch back it continues where it left off. This is the code I'm using to play the sound: NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/audio.mp3", [[NSBundle mainBundle] resourcePath]]]; NSError *error; audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error]; audioPlayer.numberOfLoops = -1; if (audioPlayer == nil) NSLog(@"%@", [error userInfo]); else [audioPlayer play]; Has anyone gotten this to work? Could it be that it would work on an actual device and it's just a problem with the simulator? I'm a bit hesitant to install 4.0 on my phone since I've heard it's still very buggy. Wish I had another device to use only for development.

  • UIActivityIndicator on UITableViewCell not displaying while calling a webService

    - by Yoyi Cheika
    Hi coders, I guess my problem is very simple to solve but I haven been able to do so. Here is my problem: I have a custom table view cell that contains a UIActivityIndicator. When a cell is selected I push another view but this second view makes a call to a web service to bring data. Here is my code // Override to support row selection in the table view. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // Navigation logic may go here -- for example, create and push another view controller. // AnotherViewController *anotherViewController = [[AnotherViewController alloc] initWithNibName:@"AnotherView" bundle:nil]; // [self.navigationController pushViewController:anotherViewController animated:YES]; // [anotherViewController release]; Models *models = [[Models alloc] initWithNibName:@"Models" bundle:nil]; models.make = ((MakeCell *)[tableView cellForRowAtIndexPath:indexPath]).make.text; models.year = (int)[self.yearLabel.text doubleValue]; models.logo = [makeLogosName objectAtIndex:indexPath.row]; [((MakeCell *)[tableView cellForRowAtIndexPath:indexPath]).activityIndicator startAnimating]; [self.navigationController pushViewController:models animated:YES]; [((MakeCell *)[tableView cellForRowAtIndexPath:indexPath]).activityIndicator stopAnimating]; [models release]; } Where MakeCell is my custom cell. If I comment this line [((MakeCell *)[tableView cellForRowAtIndexPath:indexPath]).activityIndicator stopAnimating]; then the indicator appears as expected when going back to the previous view. I feel like the indicator is not being visually updated until the didSelectRowAtIndexPath returns. Does is works ascyncronically. What can be my problem here. Thank you very much Cheika

  • MSMQ on Win2008 R2 won’t receive messages from older clients

    - by Graffen
    Hi all I'm battling a really weird problem here. I have a Windows 2008 R2 server with Message Queueing installed. On another machine, running Windows 2003 is a service that is set up to send messages to a public queue on the 2008 server. However, messages never show up on the server. I've written a small console app that just sends a "Hello World" message to a test queue on the 2008 machine. Running this app on XP or 2003 results in absolutely nothing. However, when I try running the app on my Windows 7 machine, a message is delivered just fine. I've been through all sorts of security settings, disabled firewalls on all machines etc. The event log shows nothing of interest, and no exceptions are being thrown on the clients. Running a packet sniffer (WireShark) on the server reveals only a little. When trying to send a message from XP or 2003 I only see an ICMP error "Port Unreachable" on port 3527 (which I gather is an MQPing packet?). After that, silence. Wireshark shows a nice little stream of packets when I try from my Win7 client (as expected - messages get delivered just fine from Win7). I've enabled MSMQ End2End logging on the server, but only entries from the messages sent from my Win7 machine are appearing in the log. So somehow it seems that messages are being dropped silently somewhere along the route from XP or 2003 to my 2008 server. Does anyone have any clues as to what might be causing this mysterious behaviour? -- Jesper

  • Considerations when architecting an extensible application using MEF

    - by Dan Bryant
    I've begun experimenting with dependency injection (in particular, MEF) for one of my projects, which has a number of different extensibility points. I'm starting to get a feel for what I can do with MEF, but I'd like to hear from others who have more experience with the technology. A few specific cases: My main use case at the moment is exposing various singleton-like services that my extensions make use of. My Framework assembly exposes service interfaces and my Engine assembly contains concrete implementations. This works well, but I may not want to allow all of my extensions to have access to all of my services. Is there a good way within MEF to limit which particular imports I allow a newly instantiated extension to resolve? This particular application has extension objects that I repeatedly instantiate. I can import multiple types of Controllers and Machines, which are instantiated in different combinations for a Project. I couldn't find a good way to do this with MEF, so I'm doing my own type discovery and instantiation. Is there a good way to do this within MEF or other DI frameworks? I welcome input on any other things to watch out for or surprising capabilities you've discovered that have changed the way you architect.

  • Uncatchable AccesViolationException

    - by Roy
    Hi all, I'm getting close to desperate.. I am developing a field service application for Windows Mobile 6.1 using C# and quite some p/Invoking. (I think I'm referencing about 50 native functions) On normal circumstances this goes without any problem, but when i start stressing the GC i'm getting a nasty 0xC0000005 error witch seems uncatchable. In my test i'm rapidly closing and opening a dialog form (the form did make use of native functions, but for testing i commented these out) and after a while the Windows Mobile error reporter comes around to tell me that there was an fatal error in my application. My code uses a try-catch around the Application.Run(masterForm); and hooks into the CurrentDomain.UnhandledException event, but the application still crashes. Even when i attach the debugger, visual studio just tells me "The remote connection to the device has been lost" when the exception occurs.. Since I didn't succeed to catch the exception in the managed environment, I tried to make sense out of the Error Reporter log file. But this doesn't make any sense, the only consistent this about the error is the application where it occurs in. The thread where the application occurs in is unknown to me, the module where the error occurs differs from time to time (I've seen my application.exe, WS2.dll, netcfagl3_5.dll and mscoree3_5.dll), even the error code is not always the same. (most of the time it's 0xC0000005, but i've also seen an 0X80000002 error, which is a warning accounting the first byte?) I tried debugging through bugtrap, but strangely enough this crashes with the same error code (0xC0000005). I tried to open the kdmp file with visual studio, but i can't seem to make any sense out of this because it only shows me disassembler code when i step into the error (unless i have the right .pbb files, which i don't). Same goes for WinDbg. To make a long story short: I frankly don't have a single clue where to look for this error, and I'm hoping some bright soul on stackoverflow does. I'm happy to provide some code but at this moment I don't know which piece to provide.. Any help is greatly appreciated!

  • c# webbrowser | pushed realtime quotes

    - by Eric
    Hi, I am programmer and share trader. Before I have written a day trading application. Until last week it was possible to fetch realtime quotes from http://aktien.boerse.de/aktien_startseite.php?view=2&order=name%20asc&liste=prime&page=0 . Every time the site was surfed the quotes had changed. The HTML contents could then be decoded with regular expressions (regex). Problem They have stopped this service by today. Now the quotes are not realtime when surfing on the page. The only way to get stock quotes now is to use pushed quotes "Push starten"-Button. However I do not know how to basically fetch them in C#. When I create a webbrowser element the only way which I know to get the push quotes out of it is to give the webbrowser element the focus send key ctrl+A and ctrl+C and insert the data some where for decoding. This is not desired since the control is moved away from the user and in case some other control is clicked during the process this may result in unexpected behaviour. Question So is there a proper way to decode push stock quotes in C#? Thanks a lot in advance, --eric

  • C# WPF DataBind boolean

    - by jtdangelo
    I have been using this website to learn a lot about C# for a while, but this is my first time posting a question. I look forward to hearing back from some of the seasoned C# veterans! I have been working on a C# 4.0 WPF project and need to figure out how to databind a boolean value. I have a reference to my Application.Current object in a window. My "App" object contains a boolean field called "Downloaded" that is true if the user has downloaded information from a web service. I need to databind a textbox's IsEnabled field to this Downloaded value. Any tips? Here is what I have come up with so far. (Any useful links to better learn WPF XAML are greatly appreciated!) C# Code: class MainWindow : Window { ... private App MyApp = App.Current as App; ... } XAML: <TextBox ... IsEnabled="{Binding Source=MyApp, Path=Downloaded}" /> James

  • Red5 Unable to Start Distribution.

    - by Iscariot
    I have installed subclipse, Ant, IvyDE, Red5 Plugin for eclipse, All of the Environmental variables are set and the necessary elements have been added to the path. I am attempting to create a Red5 Distribution by using eclipse, opening Build.xml right clicking dist [default] in the outline window and running as and selecting Ant Builder. Eclipse says that the build is Successful. I first stop the Red5 Service, and then I attempt to run the build I create in eclipse it fails, below are the errors that display in the command prompt. I was hoping someone else might have run into a similar issue before.

  • https google urlshortener request missing body

    - by Peter
    Hi, Just trying to get the new API for the goo.gl URL shortening service working on my iPhone, following the instructions on http://code.google.com/apis/urlshortener/v1/getting_started.html I'm set up and the API is enabled etc., but when I send a request in the recommended format: POST https://www.googleapis.com/urlshortener/v1/url Content-Type: application/json {"longUrl": "http://www.google.com/"} I get an error returned. The error is exactly the one listed on that page in the errors section for if you haven't passed in a longURL param. This makes me think that I'm not setting up the body of the POST request properly. Here's the code if you have any pointers... NSString *longURLString=@"http://www.stackoverflow.com"; NSString *googlRequestString=@"https://www.googleapis.com/urlshortener/v1/url"; NSMutableURLRequest *request=[NSMutableURLRequest requestWithURL:[NSURL URLWithString:googlRequestString]]; [request setHTTPMethod:@"POST"]; [request addValue:@"application/json" forHTTPHeaderField:@"Content-Type:"]; NSString *bodyString=[NSString stringWithFormat:@"{\"longUrl\": \"%@\"}",longURLString]; [request setHTTPBody:[bodyString dataUsingEncoding:NSUTF8StringEncoding]]; NSURLResponse *theResponse; NSError *error=nil; NSData *receivedData=[NSURLConnection sendSynchronousRequest:request returningResponse:&theResponse error:&error]; NSString *receivedString=[[NSString alloc] initWithData:receivedData encoding:NSUTF8StringEncoding]; NSLog(@"Received data: %@",receivedString); [receivedString release]; The NSLog returns: Received data: { "error": { "errors": [ { "domain": "global", "reason": "required", "message": "Required", "locationType": "parameter", "location": "resource.longUrl" } ], "code": 400, "message": "Required" } } which is exactly what Google says you get if you have not passed a longUrl parameter.... My guess is I'm missing something very obvious here :-) P

  • check status application pool iis7 with csharp (access-denied)

    - by jack
    I need to monitor the status of an application in the applications pool of IIS 7 from an other machine on the same domain. My monitoring application must be in C# and running as a Windows service. On my server, I create a user with administration rights and I execute the command aspnet_regiis -ga machine\username wich worked succesfully. My problem is when I try to access the application pool i still get COMExcepttion "Access denied". What did i do wrong or wich step did i miss? I used code from http://patelshailesh.com/index.php/create-a-website-application-pool-programmatically-using-csharp as example. int status = 0; string ipAddress = "10.20.2.13"; string username = "username"; string password = "password"; try { DirectoryEntry de = new DirectoryEntry(string.Format("IIS://{0}/W3SVC/AppPools/MyAppPoolName", ipAddress), username, password); //the exception is thron here. status = (int)de.InvokeGet("AppPoolState"); switch (status) { case 2: //Runnig break; case 4: //Stopped break; default: break; } } catch (Exception ex) { }
