• WCF service The maximum array length quota (16384) has been exceeded

  - by dmitry.baranovsky

  I have a wsf service and a client application. While trying to communicate the client and the service I've gotten the following message: "The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://tempuri.org/:blob. The InnerException message was 'There was an error deserializing the object of type FileBlob. The maximum array length quota (16384) has been exceeded while reading XML data. This quota may be increased by changing the MaxArrayLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader. Line 1, position 25931.'. Please see InnerException for more details." I have the customBinding element and it doesn't allow me to insert "readerQuotas" section. In both the client and service configs I have the following binding element: <customBinding> <binding name="LicenseServiceBinding" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"> <security authenticationMode="UserNameOverTransport"> <localClientSettings maxClockSkew="00:07:00" /> <localServiceSettings maxClockSkew="00:07:00" /> </security> <windowsStreamSecurity /> <httpsTransport maxReceivedMessageSize="2147483646"/> </binding> </customBinding> Thanks in advance for any help:)

• iPad popover textfield - resignFirstResponder doesn't dismiss keyboard

  - by mosdev

  I have two text fields email and password. The following code works fine when the fields are presented on a regular view but when they are on a popover, the resignFirstResponder does not work (becomeFirstResponder works). textFieldsShouldReturn was called for both fields. Any idea if I am missing something? Thanks! - (BOOL)textFieldShouldReturn:(UITextField *)theTextField { if (theTextField == email) { [password becomeFirstResponder]; return NO; } [theTextField resignFirstResponder]; return NO; }

• Django-Registration & Django-Profile, using your own custom form

  - by Issy

  Hey All, I am making use of django-registration and django-profile to handle registration and profiles. I would like to create a profile for the user at the time of registration. I have created a custom registration form, and added that to the urls.py using the tutorial on: http://dewful.com/?p=70 The basic idea in the tutorial is to override the default registration form to create the profile at the same time. forms.py - In my profiles app from django import forms from registration.forms import RegistrationForm from django.utils.translation import ugettext_lazy as _ from profiles.models import UserProfile from registration.models import RegistrationProfile attrs_dict = { 'class': 'required' } class UserRegistrationForm(RegistrationForm): city = forms.CharField(widget=forms.TextInput(attrs=attrs_dict)) def save(self, profile_callback=None): new_user = RegistrationProfile.objects.create_inactive_user(username=self.cleaned_data['username'], password=self.cleaned_data['password1'], email=self.cleaned_data['email']) new_profile = UserProfile(user=new_user, city=self.cleaned_data['city']) new_profile.save() return new_user In urls.py from profiles.forms import UserRegistrationForm and url(r'^register/$', register, {'backend': 'registration.backends.default.DefaultBackend', 'form_class' : UserRegistrationForm}, name='registration_register'), The form is displayed, and i can enter in City, however it does not save or create the entry in the DB.

• WCF deadlock when using callback channel

  - by mafutrct

  This is probably a simple mistake, but I could not figure out what was wrong. I basically got a method like this: [ServiceBehavior ( ConcurrencyMode = ConcurrencyMode.Reentrant, InstanceContextMode = InstanceContextMode.PerSession, IncludeExceptionDetailInFaults = true) ] public class Impl : SomeContract { public string Foo() { _CallbackChannel.Blah(); return ""; } } Its interface is decorated: [ServiceContract ( Namespace = "http://MyServiceInterface", SessionMode = SessionMode.Required, CallbackContract = typeof (WcfCallbackContract)) ] public interface SomeContract { [OperationContract] string Foo (); } The service is hosted like this: ServiceHost host = new ServiceHost (typeof (Impl)); var binding = new NetTcpBinding (); var address = new Uri ("net.tcp://localhost:8000/"); host.AddServiceEndpoint ( typeof (SomeContract), binding, address); host.Open (); The client implements the callback interface and calls Foo. Foo runs, calls the callback method and returns. However, the client is still struck in the call to Foo and never returns. The client callback method is never run. I guess I made a design mistake somewhere. If needed, I can post more code. Any help is appreciated.

• jquery datatables add checkbox with ajax server side response

  - by dotneter

  I am using C# ASP .NET MVC and ajax calls. I am able to get the display of the table along with all features. But, I don't understand how do I add a checkbox and button.

• Crazy idea: Connect .NET and SAP with SAP JCo using IKVM.NET

  - by Kottan

  Because the SAP Connector for .NET is no longer maintained by SAP, I am now looking for an alternative to connect the Microsoft world with the SAP world. I know there a third party products like ERPConnect, but I want to do this with tools from SAP. Therefore there arised the crazy idea to use the SAP Java Connector in combination with the tool IKVM.NET (www.ikvm.net/devguide/net2java.html). IKVM.NET provides The IKVMC tool, which converts Java bytecode to .NET dll's and exe's. "No sooner said than done!" I converted the SAP JCo to .NET dlls and created a new Visual Studio solution. I put all the JCO files into a subdirectory of my solution. I set 2 references to the generated IKVM.OpenJDK.Core.dll and sapjco.dll. Great, all JCO classes where now available as .NET classes. Full of optimism I wrote some little code to connect to a SAP system. JCO.Client client = null; client = JCO.createClient(...) The compiliation of my testcode had no errors. "Wonderful !" I thought. Then I started my tetstapplication. Unfortunately I got an exception calling JCO.createClient: Could not load middleware layer 'com.sap.mw.jco.rfc.MiddlewareRFC'\r\nno sapjcorfc in java.library.path I have 2 questions on this topic. 1) Do you think my idea using SAP Java Connector to connect .NET with SAP is a good idea or is it nonsens ? Perhaps someone had already the same idea ;-) 2) How can the above exception be solved ?

• Webclient using download file to grab file from server - handling exceptions

  - by baron

  Hello everyone, I have a web service in which I am manipulating POST and GET methods to facilitate upload / download functionality for some files in a client/server style architecture. Basically the user is able to click a button to download a specific file, make some changes in the app, then click upload button to send it back. Problem I am having is with the download. Say the user expects 3 files 1.txt, 2.txt and 3.txt. Except 2.txt does not exist on the server. So I have code like (on server side): public class HttpHandler : IHttpHandler { public void ProcessRequest { if (context.Request.HttpMethod == "GET") { GoGetIt(context) } } private static void GoGetIt(HttpContext context) { var fileInfoOfWhereTheFileShouldBe = new FileInfo(......); if (!fileInfoOfWhereTheFileShouldBe.RefreshExists()) { throw new Exception("Oh dear the file doesn't exist"); } ... So the problem I have is that when I run the application, and I use a WebClient on client side to use DownloadFile method which then uses the code I have above, I get: WebException was unhandled: The remote server returned an error: (500) Internal Server Error. (While debugging) If I attach to the browser and use http://localhost:xxx/1.txt I can step through server side code and throw the exception as intended. So I guess I'm wondering how I can handle the internal server error on the client side properly so I can return something meaningful like "File doesn't exist". One thought was to use a try catch around the WebClient.DownloadFile(address, filename) method but i'm not sure thats the only error that will occur i.e. the file doesn't exist.

• Check username and password in LINQ query

  - by b0x0rz

  this linq query var users = from u in context.Users where u.UserEMailAdresses.Any(e1 => e1.EMailAddress == userEMail) && u.UserPasswords.Any(e2 => e2.PasswordSaltedHash == passwordSaltedHash) select u; return users.Count(); returns: 1 even when there is nothing in password table. how come? what i am trying to do is get the values of email and passwordHash from two separate tables (UserEMailAddresses and UserPasswords) linked via foreign keys to the third table (Users). it should be simple - checking if email and password mach from form to database. but it is not working for me. i get 1 (for count) even when there are NO entries in the UserPasswords table. is the linq query above completely wrong, or...?

• C# code to GZip and upload a string to Amazon S3

  - by BigJoe714

  Hello. I currently use the following code to retrieve and decompress string data from Amazon C#: GetObjectRequest getObjectRequest = new GetObjectRequest().WithBucketName(bucketName).WithKey(key); using (S3Response getObjectResponse = client.GetObject(getObjectRequest)) { using (Stream s = getObjectResponse.ResponseStream) { using (GZipStream gzipStream = new GZipStream(s, CompressionMode.Decompress)) { StreamReader Reader = new StreamReader(gzipStream, Encoding.Default); string Html = Reader.ReadToEnd(); parseFile(Html); } } } I want to reverse this code so that I can compress and upload string data to S3 without being written to disk. I tried the following, but I am getting an Exception: using (AmazonS3 client = Amazon.AWSClientFactory.CreateAmazonS3Client(AWSAccessKeyID, AWSSecretAccessKeyID)) { string awsPath = AWSS3PrefixPath + "/" + keyName+ ".htm.gz"; byte[] buffer = Encoding.UTF8.GetBytes(content); using (MemoryStream ms = new MemoryStream()) { using (GZipStream zip = new GZipStream(ms, CompressionMode.Compress)) { zip.Write(buffer, 0, buffer.Length); PutObjectRequest request = new PutObjectRequest(); request.InputStream = ms; request.Key = awsPath; request.BucketName = AWSS3BuckenName; using (S3Response putResponse = client.PutObject(request)) { //process response } } } } The exception I am getting is: Cannot access a closed Stream. What am I doing wrong?

• XMPP and Android interaction

  - by Ameya Phadke

  I am currently finding about how to build a XMPP client application on android 2.0.I came across this link which somewhat talks about the same problem.I am a newbie to android dev and thus found the solution given there to be difficult to digest. The system currently has Active MQ as a JMS provider.My job is to fed the messages coming from JMS to the XMPP server and then develope XMPP client on android 2.0 which will listen and show notification to the events pushed by the server. I have following concerns(which might sound foolish) 1.How do I push the events from JMS to the XMPP server which will in turn push them on android? 2.Which XMPP server implementation I should use?I have 3 options * Openfire: Very mature (was a commercial product), but sounds like it's heavyweight, written in Java * Prosody: Lightweight and easy to use, written in Lua. Doesn't have PubSub module yet * Tigase: Also lightweight, written in Java, supports PubSub How do I test and setup these servers.Do I need PubSub funcationality for my app? 3.For XMPP client I came across Smack API given here which is updated like 2 years back.Can anyone please tell me how do I make use of it for Android 2.0.If possible can anyone please mail me latest working Smack jar files. Thanks, Ameya

• BlackBerry Simulator & BIS Push Service

  - by Submerged

  I am hoping that someone knows if you can use RIMM's push service with BIS WITHOUT a hand held device. I have registered for the push evaluation and I want to program a push server that will send out notifications to BB clients. I got my email this morning containing: Server: Application: XXXXXXXXXXXXXXXXXXX Pwd: xxxXXXXX CPID (Content Provider ID):xxx Start Date (MM/DD/YYYY): X/X/XXXX Expiry Date (MM/DD/YYYY):X/X/XXXX First Name:XXXXXXX Last Name:XXXXX Email:[email protected] Account Type:Plus Source IP:xxx.xxx.xxx.xxx Usage:BIS AND Client: Application Credentials (for use in your client application): Application ID:XXX-xxxxxxxxxxxxxxx Push Port:xxxxx I am hoping someone can tell me where to get started - as an iPhone developer, I have to say, there is much more information. Lastly, if I DO need a device, does that device have to have a dataplan? I wanted to be able to serve my clients from WiFi as well, does the BB push system work only on Cell networks? Thank you

• Improving long-polling Ajax performance

  - by Bears will eat you

  I'm writing a webapp (Firefox-compatible only) which uses long polling (via jQuery's ajax abilities) to send more-or-less constant updates from the server to the client. I'm concerned about the effects of leaving this running for long periods of time, say, all day or overnight. The basic code skeleton is this: function processResults(xml) { // do stuff with the xml from the server } function fetch() { setTimeout(function () { $.ajax({ type: 'GET', url: 'foo/bar/baz', dataType: 'xml', success: function (xml) { processResults(xml); fetch(); }, error: function (xhr, type, exception) { if (xhr.status === 0) { console.log('XMLHttpRequest cancelled'); } else { console.debug(xhr); fetch(); } } }); }, 500); } (The half-second "sleep" is so that the client doesn't hammer the server if the updates are coming back to the client quickly - which they usually are.) After leaving this running overnight, it tends to make Firefox crawl. I'd been thinking that this could be partially caused by a large stack depth since I've basically written an infinitely recursive function. However, if I use Firebug and throw a breakpoint into fetch, it looks like this is not the case. The stack that Firebug shows me is only about 4 or 5 frames deep, even after an hour. One of the solutions I'm considering is changing my recursive function to an iterative one, but I can't figure out how I would insert the delay in between Ajax requests without spinning. I've looked at the JS 1.7 "yield" keyword but I can't quite wrap my head around it, to figure out if it's what I need here. Is the best solution just to do a hard refresh on the page periodically, say, once every hour? Is there a better/leaner long-polling design pattern that won't put a hurt on the browser even after running for 8 or 12 hours? Or should I just skip the long polling altogether and use a different "constant update" pattern since I usually know how frequently the server will have a response for me?

• validating an XML schema with empty attributes

  - by AdRock

  I am having trouble validating my xml schema. I get these errors on the schema 113: 18 s4s-elt-invalid-content.1: The content of '#AnonType_user' is invalid. 164: 17 s4s-elt-invalid-content.1: The content of '#AnonType_festival' is invalid. Element 'sequence' is invalid, misplaced, or occurs too often. and becuase of those 2 errors, i am getting loads of the same error.

  I am attempting to insert a custom behavior into my service client, following the example here. I appear to be following all of the steps, but I am getting a ConfigurationErrorsException.

• WCF/MSMQ Transport Security with Certificates

  - by user104295

  Hi there, my goal is to secure the communication between MSMQ Queue Managers – I don’t want unknown clients sending messages to my MSMQ server. I have spent many hours now trying to get Transport security working for the net.msmq binding in WCF, where MSMQ is in Workgroup mode and the client and server do not have Active Directory… so I’m using certificates. I have created a new X.509 certificate, called Kristan and put it into the “Trusted people” store on the server and into the My store of Current User of the client. The error I’m getting is: An error occurred while sending to the queue: Unrecognized error -1072824272 (0xc00e0030).Ensure that MSMQ is installed and running. If you are sending to a local queue, ensure the queue exists with the required access mode and authorization. Using smartsniff, I see that there’s no attempted connection with the remote MSMQ, however, it’s an error probably coming from the local queue manager. The stack trace is: at System.ServiceModel.Channels.MsmqOutputChannel.OnSend(Message message, TimeSpan timeout) at System.ServiceModel.Channels.OutputChannel.Send(Message message, TimeSpan timeout) at System.ServiceModel.Dispatcher.OutputChannelBinder.Send(Message message, TimeSpan timeout) at System.ServiceModel.Channels.ServiceChannel.Call(String action, Boolean oneway, ProxyOperationRuntime operation, Object[] ins, Object[] outs, TimeSpan timeout) at System.ServiceModel.Channels.ServiceChannelProxy.InvokeService(IMethodCallMessage methodCall, ProxyOperationRuntime operation) at System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage message) The code:- EndpointAddress endpointAddress = new EndpointAddress(new Uri(endPointAddress)); NetMsmqBinding clientBinding = new NetMsmqBinding(); clientBinding.Security.Mode = NetMsmqSecurityMode.Transport; clientBinding.Security.Transport.MsmqAuthenticationMode = MsmqAuthenticationMode.Certificate; clientBinding.Security.Transport.MsmqProtectionLevel = System.Net.Security.ProtectionLevel.Sign; clientBinding.ExactlyOnce = false; clientBinding.UseActiveDirectory = false; // start new var channelFactory = new ChannelFactory<IAsyncImportApi>(clientBinding, endpointAddress); channelFactory.Credentials.ClientCertificate.SetCertificate("CN=Kristan", StoreLocation.CurrentUser, StoreName.My); The queue is flagged as ‘Authenticated’ on the server. I have checked the effect of this and if I turn off all security in the client send, then I get ‘Signature is invalid’ – which is understandable and shows that it’s definitely looking for a sig. Are there are special ports that I need to check are open for cert-based msmq auth? thanks Kris

• Setting freemarker template from classpath

  - by wuntee

  I have a web application that I need to manually obtain a Freemarker template - the template is obtained via a class in a library project, but the actual tpl file is contained in the web application classpath. So, there are 2 projects, one 'taac-backend-api' and another 'taac-web'; taac-backend-api has the code to grab the template, and process it, but taac-web is where the template is stores (specifically in: WEB-INF/classes/email/vendor.tpl) - I have tried everything from using springs classpath resource to using Freemarkers setClassForTemplateLoading method. I assume this would work: freemarkerConfiguration = new Configuration(); freemarkerConfiguration.setClassForTemplateLoading(this.getClass(), ""); Template freemarkerTemplate = freemarkerConfiguration.getTemplate("/email/vendor.tpl"); yet, I always get a FileNotFoundException. Can someone explain the best way to obtain a template from the classpath? Thanks.

• jsf datatable lazy load filter and sorting

  - by darko petreski

  Hi, I have worked on several projects with a lot of data tables. The tables had sorting, filtering and paging of course on server side and with help of the db (all databases has implemented sording, filtering -where and limit the returned results). When workig on real application there are a thousands of even a millions rows. But I have seen several JSF dagatable components. They implement pagination, sorting and filtering on client side!! According to me this is very silly. This technology is called enterprise and they sort the data on the client side with java script! I have not seen any good JSF data grid that has build in features for sorting, filtering and lazy loading on the server side. Why is that? Am I looking in wrong direction or really there in no build support for this. Lately I am testing primefaces and lazy loading datatable. It really works fine, but the table i can only lazy load. If you add sort and filter then the problems begin. Conclusion: Is there any datatable JSF component than can perform lazy load pagination, and filtering and sorting on server side. If I need to implement my own solution thanks to the teams that made client side sorting and filtering, they are useless. Regards

• SharePoint custom web service consumption problems - HTTP 401: Unauthorized

  - by alekz

  I have a custom web service deployed into WSS 3. It has two web methods. The first one returns the version of the loaded assembly without any invocation of the SharePoint objects. The second returns some basic info about the library, something like: var spLibrary = [find library logic]; return spLibrary.Name+"@"+spLibrary.Url; In the client app I have something like the following: var service = new WebService1(); service.Url = [url]; service.Credentials = System.Net.CredentialCache.DefaultCredentials; service.Method1(); service.Method2(); When the client app runs on the machine where SharePoint is deployed, everything works just fine. When the client app runs on the remote machine (but under the same user) the first method still works, but the second one throws System.Net.WebException: HTTP 401: Unauthorized. I have tried to set credentials manualy (service.Credentials = new System.Net.NetworkCredential(login, password, domain);) but this doesnt help. I've tried to invoke the built in SharePoint web services using a similar scenario, and they work just fine: Sorry for the mistake... Some methods were not working fine without the appropriate privileges. var service = new GroupsService(); service.Url = [url]; service.Credentials = System.Net.CredentialCache.DefaultCredentials; service.SomeMethod();

• How to use an out-of-process COM server without its tlb file

  - by Dbger

  It is about Window COM component. Server.exe: an 32bit out-of-process COM server CLSID_Application: The GUID of a COM object in Server.exe Client.exe: a 64bit client application which use Server.exe in a registry-free way. As we know, an exe can't be used as a registry-free COM component, to mimic such behavior, I start the Server.exe process myself by providing the exact path: CreateProcess("Server.exe") IClassFactory* pFactory = CoGetClassObject(CLSID_Application) pFactory-CreateInstance(ppAppObject); It works if I have the Server.tlb registred, but after unregister Server.tlb, it just failed to create the ppAppObject, even though I embed manifest into both Server.exe and Client.exe: <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <file name="Server.tlb"> <typelib tlbid="{DAC4A4C9-F84C-4F05-A7DC-E152869499F5}" version="1.0" helpdir=""></typelib> </file> <comInterfaceExternalProxyStub name="IApplication" iid="{D74208EA-71C2-471D-8681-9760B8ECE599}" tlbid="{DAC4A4C9-F84C-4F05-A7DC-E152869499F5}" proxyStubClsid32="{00020424-0000-0000-C000-000000000046}"></comInterfaceExternalProxyStub> </assembly> Do you have any idea on this? Edit: It turns out that it really works if I specify tlbid for interfaces, and embed the manifest to both exe

• Creating settings like the Mail settings in the Settings app

  I want to create some settings much like the Mail settings within the Settings app. These allow you to add mail accounts to the end of the table First screen --------------- + | add account | --------------- When they click on the cell, they are pushed onto a new screen where they fill in a few textfields Second screen ----------------- |(cancel) (save)| - the toolbar ----------------- ---------------- | email | ---------------- |another field | ---------------- Then when they go back, they can see the new record as well as the 'add account' cell. First screen --------------- | email 1 | --------------- + | add account | --------------- It need to be in-app rather than within the Settings app. What's the best way to do this?

• Three ways to upload/post/convert iMovie to YouTube

  - by user351686

  For Mac users, iMovie is probably a convenient tool for making, editing their own home movies so as to upload to YouTube for sharing with more people. However, uploading iMovie files to YouTube can't be always a smooth run, I did notice many people complaining about it. This article is delivered for guiding those who are haunted by the nightmare by providing three common ways to upload iMovie files to YouTube. YouTube and iMovie YouTube is the most popular video sharing website for users to upload, share and view videos. It empowers anyone with an Internet connection the ability to upload video clips and share them with friends, family and the world. Users are invited to leave comments, pick favourites, send messages to each other and watch videos sorted into subjects and channels. YouTube accepts videos uploaded in most container formats, including WMV (Windows Media Video), 3GP (Cell Phones), AVI (Windows), MOV (Mac), MP4 (iPod/PSP), FLV (Adobe Flash), MKV (H.264). These include video codecs such as MP4, MPEG and WMV. iMovie is a common video editing software application comes with every Mac for users to edit their own home movies. It imports video footage to the Mac using either the Firewire interface on most MiniDV format digital video cameras, the USB port, or by importing the files from a hard drive where users can edit the video clips, add titles, and add music. Since 1999, eight versions of iMovie have been released by Apple, each with its own functions and characteristic, and each of them deal with videos in a way more or less different. But the most common formats handled with iMovie if specialty discarded as far as to my research are MOV, DV, HDV, MPEG-4. Three ways for successful upload iMovie files to YouTube Solution one and solution two suitable for those who are 100 certainty with their iMovie files which are fully compatible with YouTube. For smooth uploading, you are required to get a YouTube account first. Solution 1: Directly upload iMovie to YouTube Step 1: Launch iMovie, select the project you want to upload in YouTube. Step 2: Go to the file menu, click Share, select Export Movie Step 3: Specify the output file name and directory and then type the video type and video size. Solution 2: Post iMovie to YouTube straightly Step 1: Launch iMovie, choose the project you want to post in YouTube Step 2: From the Share menu, choose YouTube Step 3: In the pop-up YouTube windows, specify the name of your YouTube account, the password, choose the Category and fill in the description and tags of the project. Tick Make this movie more private on the bottom of the window, if possible, to limit those who can view the project. Click Next, and then click Publish. iMovie will automatically export and upload the movie to YouTube. Step 4: Click Tell a Friend to email friends and your family about your film. You are also allowed to copy the URL from Tell a Friend window and paste it into an email you created in your favourite email application if you like. Anyone you send to email to will be able to follow the URL directly to your movie. Note: Videos uploaded to YouTube are limited to ten minutes in length and a file size of 2GB. Solution 3: Upload to iMovie after conversion If neither of the above mentioned method works, there is still a third way to turn to. Sometimes, your iMovie files may not be recognized by YouTube due to the versions of iMovie (settings and functions may varies among versions), video itself (video format difference because of file extension, resolution, video size and length), compatibility (videos that are completely incompatible with YouTube). In this circumstance, the best and reliable method is to convert your iMovie files to YouTube accepted files, iMovie to YouTube converter will be inevitably the ideal choice. iMovie to YouTube converter is an elaborately designed tool for convert iMovie files to YouTube workable WMV, 3GP, AVI, MOV, MP4, FLV, MKV for smooth uploading with hard-to-believe conversion speed and second to none output quality. It can also convert between almost all popular popular file formats like AVI, WMV, MPG, MOV, VOB, DV, MP4, FLV, 3GP, RM, ASF, SWF, MP3, AAC, AC3, AIFF, AMR, WAV, WMA etc so as to put on various portable devices, import to video editing software or play on vast amount video players. iMovie to YouTube converter can also served as an excellent video editing tool to meet your specific program requirements. For example, you can cut your video files to a certain length, or split your video files to smaller ones and select the proper resolution suitable for demands of YouTube by Clip or Settings separately. Crop allows you to cut off unwanted black edges from your videos. Besides, you can also have a good command of the whole process or snapshot your favourite pictures from the preview window. More can be expected if you have a try.

• Sync Vs. Async Sockets Performance in C#

  - by Michael Covelli

  Everything that I read about sockets in .NET says that the asynchronous pattern gives better performance (especially with the new SocketAsyncEventArgs which saves on the allocation). I think this makes sense if we're talking about a server with many client connections where its not possible to allocate one thread per connection. Then I can see the advantage of using the ThreadPool threads and getting async callbacks on them. But in my app, I'm the client and I just need to listen to one server sending market tick data over one tcp connection. Right now, I create a single thread, set the priority to Highest, and call Socket.Receive() with it. My thread blocks on this call and wakes up once new data arrives. If I were to switch this to an async pattern so that I get a callback when there's new data, I see two issues The threadpool threads will have default priority so it seems they will be strictly worse than my own thread which has Highest priority. I'll still have to send everything through a single thread at some point. Say that I get N callbacks at almost the same time on N different threadpool threads notifying me that there's new data. The N byte arrays that they deliver can't be processed on the threadpool threads because there's no guarantee that they represent N unique market data messages because TCP is stream based. I'll have to lock and put the bytes into an array anyway and signal some other thread that can process what's in the array. So I'm not sure what having N threadpool threads is buying me. Am I thinking about this wrong? Is there a reason to use the Async patter in my specific case of one client connected to one server?

• How to update model?

  - by Alexander Efimov

  Hi, guys. I have an ASP.NET MVC page where the model is being edited. On each action executing I have a new controller, so I don't get an updated model. I'm saving a model instance into Session["MyModelKey"]. But every time an action is executed, I have unmodified instance there even if I have changed values in textboxes which were created like this: @Html.LabelFor(model = model.EMail) @Html.TextBoxFor(model = model.EMail) @Html.LabelFor(model = model.Country) @Html.TextBoxFor(model = model.Country) @Html.ActionLink("MyAction", "MyController") Controller: public class MyController : Controller { public ActionResult MyAction() { //Every time this action is executed - I have a new controller instance //So I have null in View.Model //I get Session["MyModelKey"] here, //But the model instance properties are not updated //even though I have updated E-mail and Country properties of the model in the UI } } So, how can I get an updated model? Thanks in advance.
