  • MVC2 client/server validation of DateTime/Date using DataAnnotations

    - by Thomas
    The following are true: One of my columns (BirthDate) is of type Date in SQL Server. This very same column (BirthDate) is of type DateTime when EF generates the model. I am using JQuery UI Datepicker on the client side to be able to select the BirthDate. I have the following validation logic in my buddy class: [Required(ErrorMessageResourceType = typeof(Project.Web.ValidationMessages), ErrorMessageResourceName = "Required")] [RegularExpression(@"\b(0?[1-9]|1[012])[/](0?[1-9]|[12][0-9]|3[01])[/](19|20)?[0-9]{2}\b", ErrorMessageResourceType = typeof(Project.Web.ValidationMessages), ErrorMessageResourceName = "Invalid")] public virtual DateTime? BirthDate { get; set; } There are two issues with this: This will not pass server side validation (if I enable client side validation it works just fine). I am assuming that this is because the regular expression doesn't take into account hours, minutes, seconds as the value in the text box has already been cast as a DateTime on the server by the time validation occurs. If data already exists in the database and is read into the model and displayed on the page the BirthDate field shows hours, minutes, seconds in my text box (which I don't want). I can always use ToShortDateString() but I am wondering if there is some cleaner approach that I might be missing. Thanks

  • Spring AOP AfterThrowing vs. Around Advice

    - by whiskerz
    Hey there, when trying to implement an Aspect, that is responsible for catching and logging a certain type of error, I initially thought this would be possible using the AfterThrowing advice. However it seems that his advice doesn't catch the exception, but just provides an additional entry point to do something with the exception. The only advice which would also catch the exception in question would then be an AroundAdvice - either that or I did something wrong. Can anyone assert that indeed if I want to catch the exception I have to use an AroundAdvice? The configuration I used follows: @Pointcut("execution(* test.simple.OtherService.print*(..))") public void printOperation() {} @AfterThrowing(pointcut="printOperation()", throwing="exception") public void logException(Throwable exception) { System.out.println(exception.getMessage()); } @Around("printOperation()") public void swallowException(ProceedingJoinPoint pjp) throws Throwable { try { pjp.proceed(); } catch (Throwable exception) { System.out.println(exception.getMessage()); } } Note that in this example I caught all Exceptions, because it just is an example. I know its bad practice to just swallow all exceptions, but for my current use case I want one special type of exception to be just logged while avoiding duplicate logging logic.

  • Rendering a UIWebView in drawRect with loadHTMLString

    - by Nick Weaver
    Hello there, I am having a problem with UIWebView. I'd like to render my own html code in it. When I add a webview as a subview and put in some html code it renders just fine. When it gets down to some optimized drawing of tableview cell with the drawRect method the problem pops up. Drawing UIView descendants works pretty well this way. It's even possible to load a URL with the loadRequest method, setting the delegate, conforming to the UIWebViewDelegate protocol and redrawing the table cell with setNeedsDisplay when webViewDidFinishLoad is called. It does show, but when it comes to loadHTMLString, nothing shows up, only a white rect. Due to performance reasons I have to do the drawing in the drawRect method. Any ideas? Thanks in advance Nick Example snippet code for the html code being loaded by a UIWebView: NSString *html = @"<html><head><title>My fancy webview</title></head><body style='background-color:green;'><p>It somehow seems<h2 style='color:black;'>this does not show up in drawRect</h2>!</p></body></html>"; [webView loadHTMLString:html baseURL:nil]; Snippet for the drawRect method: - (void)drawRect:(CGRect)aRect { CGContextRef context = UIGraphicsGetCurrentContext(); [[webView layer] renderInContext:context]; }

  • Working with XML...

    - by gsvirdi
    I'm planning to create a news item which uses xml as it's backend and the Display should be like: Date: 08/Mar/2010 Title | News News 4 | Some news News 3 | Some news News 2 | Some news News 1 | Some news Date: 07/Mar/2010 Title | News News 5 | Some news News 4 | Some news News 3 | Some news News 2 | Some news News 1 | Some news Display should be sorted on Date (descending) Then news items should be sorted on time (descending) Today's news item should be on top, then titles should be sorted-decending (timewise), later will come previous day's news items. I'm not able to come up with the logic of xml which should be used in this case. moreover I'm not able to figure out how should I check "Today's date" in xml's "if" statement. ---- Previous Question ------------------------------------------------------------------ How can I export a data from textBox1, textBox2 & textBox3 on my winform (visual studio C#) so that it can automatically create an xml file with proper placing of these data???? Let's say: textBox1 = Name: textBox2 = Age: textBox3 = Roll No It would be great if the exported xml can be appended (add the new data in the EOF) if we export the data again. Any idea plz.....

  • What is best practice as far as using perl-isms (idiomatic expressions) in Perl?

    - by DVK
    A couple of years back I participated in writing the best practices/coding style for our (fairly large and often Perl-using) company. It was done by a committee of "senior" Perl developers. As anything done by consensus, it had parts which everyone disagreed with. Duh. The part that rubbed wrong the most was a strong recommendation to NOT use many Perlisms (loosely defined as code idioms not present in, say C++ or Java), such as "Avoid using '... unless X;' constructs". The main rationale posited for such rules as this one was that non-Perl developers would have much harder time with the Perl code base otherwise. The assumption here I guess is that Perl code jockeys are rarer breed overall - and among new hires to the company - than non-Perlers. I was wondering whether SO has any good arguments to support or reject this logic... it is mostly academic curiosity at this point as the company's Perl coding standard is ossified and will never be revised again as far as I'm aware. P.S. Just to be clear, the question is in the context I noted - the answer for an all-Perl smaller development shop is obviously a resounding "use Perl to its maximum capability".

  • Cannot debug views in MVC2 project, getting "The resource cannot be found" error

    - by schefdev
    I'm running Visual Studio 2008 sp1 on Win7, with MVC2 RTM installed. I created a new MVC2 project using the wizard and am unable to debug specific pages. With webforms and even MVC1, I was able to sit on a View page, hit F5, and then have the integrated web server in VS2008 start on the page I was working on. Very handy for building up app logic. When I try this now I get a "The resource cannot be found" error page. I retried this just now with a stock new MVC2 Web Application project. Here are the steps I took after creating the new project to reproduce: Open up project settings. Under the Web subtab, set the Start Action to "Current Page". Leave all the other settings as is. Open one of the views up (e.g. Account/Register.aspx) Hit F5 to debug the project Note that the browser window which displays shows the error message "The resource cannot be found". The link I saw in my browser for this run was: http://localhost:49471/Views/Account/Register.aspx I did some googling and found suggestions related to ensuring all HTTP server pieces were installed. I double checked and made sure that "HTTP Errors" and "HTTP Redirection" were both installed. If I leave the project setting as it was originally, set to "Specific Page" with nothing in the text box, then routing works and I always get the default home page. I'm hoping this isn't the only option. Thanks!

  • Windows 7 - Enable Network DTC Access

    - by Russ Clark
    I have a Visual Studio 2010 Windows Forms application in which I start a transaction using the TransactionScope class. I then Receive a message from a Sql Server Broker Services message queue, which works fine. I next try to call a stored procedure from the same database with a call to my data access layer which is a Visual Studio dataset (xsd file). When I make this second call to the database I get the following error message: The MSDTC transaction manager was unable to pull the transaction from the source transaction manager due to communication problems. Possible causes are: a firewall is present and it doesn't have an exception for the MSDTC process, the two machines cannot find each other by their NetBIOS names, or the support for network transactions is not enabled for one of the two transaction managers. (Exception from HRESULT: 0x8004D02B). I've seen several posts on the web that talk about Enabling DTC access through dcomcnfg.exe, and allowing DTC to communicate through Windows Firewall. I've done those things, and am still having this problem. I know our remote database server is setup to Enable DTC access, because we are using similar transactions in other projects built with Visual Studio 2008 on Windows XP and Vista. I think there is something specific about Windows 7 and Visual Studio 2010 causing this problem, but haven't been able to find out what it is. Can anyone help with this problem?

  • jQuery autocomplete - update options on dynamically created elements

    - by Ian Robinson
    Background The user enters values into multiple inputs on the page. Think of entering a list of widgets for sale. The user would select the type of a widget from a drop down. Then enter the name of the Widget vendor, and then the actual name of the widget. These UI elements would all appear as one row. The user is able to click an "add another widget" link and a new row is created. The two input elements have autocomplete functionality attached to them using the DevBridge jQuery plugin. It suggests the name of the vendor and the name of the widget. I have recently wired up the logic to filter the name of the widget based on the name of the vendor you entered. This means setting the (custom) vendorName parameter when attaching the autocomplete plugin so it can be passed to the server side to retrieve the widget names for that vendor that match the name the user entered. To achieve this functionality I'm dynamically attaching the autocomplete functionality to the second element (the widget name text box) when it receives focus. Here is an example: $('.autocomplete-widget').live('focus', function () { $(this).autocomplete({ serviceUrl: '/something.ashx', params: { type: 'widget', vendorName: $(this).parent().prev().find('.autocomplete-vendor').val()} }); }); Problem At first glance, this looks to function quite well. However I started noticing some inconsistencies, and upon inspection, I found out that the call to the server is actually happening several times in some cases. Each time the widget name input element receives focus the autocomplete functionality is attached. And what I'm seeing is that the call to the server is made in proportion to how many times the input element has gained focus. I'd like to avoid making the call more than once, but retain the ability to attach (or update) the autocomplete functionality "on focus". I've tried to use the autocomplete 'setOptions' method but have only been able to get it to work with the static elements, not the dynamically created elements. Question Is there a way I can clear out the autocomplete functionality before I attach another one?

  • AndroMDA maven code generation and JPA Annotations

    - by ArsenioM
    I am using the AndroMDA plugin for maven to generate code from an uml diagram made in MagicDraw. When the code is generated, AndroMDA desings the JPA annotation for the persitence layer. I think that at the compilation process AndroMDA uses Naming Strategies to determine the Table and Column names for the DataBase. I want to determine how AndroMDA desings this JPA annotations, because I need to display this DataBase names based on the UML entity and atributtes names. I was regarding if there is an API of AndroMDA that I could use to do this by giving it the uml diagram. Or at least, to know the Naming Strategies used by AndroMDA to achive that. AndroMDA at the compilation process design the JPA annotations for the Entities, Attributes, etc that are written in my java classes under a series of rules that exist within the EJB3 cartridge of AndroMDA. (The further Database is created using those JPA annotations). I want to create a program that returns me the same Table and Attributes names wrote on the JPA annotations, by giving it the .xml file of the uml diagram of a project. I was hoping that I could take advantage of the EJB3 cartridge to generate those Tables and Attribute names with my program. One way could be using an API of AndroMDA that do this(if it exits), or at least, by implementing the same rules used by the EJB3 cartridge for that matter. To be more illustrative, For example: If in my uml model I have an Entity called “CompanyGroup”, AndroMDA would generate the following code for the class definition: @javax.persistence.Entity @javax.persistence.Table(name = "COMPANY_GR") Public class CompanyGroup implements java.io.Serializable, Comparable< CompanyGroup This is just an example (not a real case), but nevertheless, the way how AndroMDA do the translation from “CompanyGroup” to “COMPANY_GR” has to be specified somewhere. Hope this explanation is useful enough. Thanks.

  • C# StreamReader.ReadLine() - Need to pick up line terminators

    - by Tony Trozzo
    I wrote a C# program to read an Excel .xls/.xlsx file and output to CSV and Unicode text. I wrote a separate program to remove blank records. This is accomplished by reading each line with StreamReader.ReadLine(), and then going character by character through the string and not writing the line to output if it contains all commas (for the CSV) or all tabs (for the Unicode text). The problem occurs when the Excel file contains embedded newlines (\x0A) inside the cells. I changed my XLS to CSV converter to find these new lines (since it goes cell by cell) and write them as \x0A, and normal lines just use StreamWriter.WriteLine(). The problem occurs in the separate program to remove blank records. When I read in with StreamReader.ReadLine(), by definition it only returns the string with the line, not the terminator. Since the embedded newlines show up as two separate lines, I can't tell which is a full record and which is an embedded newline for when I write them to the final file. I'm not even sure I can read in the \x0A because everything on the input registers as '\n'. I could go character by character, but this destroys my logic to remove blank lines. Any ideas would be greatly appreciated.

  • Add new item to UITableView and Core Data as data source?

    - by David.Chu.ca
    I have trouble to add new item to my table view with core data. Here is the brief logic in my codes. In my ViewController class, I have a button to trigle the edit mode: - (void) toggleEditing { UITableView *tv = (UITableView *)self.view; if (isEdit) // class level flag for editing { self.newEntity = [NSEntityDescription insertNewObjectForEntityName:@"entity1" inManagedObjectContext:managedObjectContext]; NSArray *insertIndexPaths = [NSArray arrayWithObjects: [NSInextPath indexPathForRow:0 inSection:0], nil]; // empty at beginning so hard code numbers here. [tv insertRowsAtIndexPaths:insertIndexPaths withRowAnimation:UITableViewRowAnimationFade]; [self.tableView setEditing:YES animated:YES]; // enable editing mode } else { ...} } In this block of codes, I added a new item to my current managed object context first, and then I added a new row to my tv. I think that both the number of objects in my data source or context and the number of rows in my table view should be 1. However, I got an exception in the event of tabView:numberOfRowsInSection: Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (0) must be equal to the number of rows contained in that section before the update (0), plus or minus the number of rows inserted or deleted from that section (1 inserted, 0 deleted). The exception was raised right after the delegate event: - (NSInteger) tableView:(UITableView *) tableView numberOfRawsInSection:(NSInteger) section { // fetchedResultsController is class member var NSFetchedResultsController id <NSFechedResultsSectionInfo> sectionInfo = [[fetchedResultsController sections] objectAtIndex: section]; NSInteger rows = [sectionInfo numberOfObjects]; return rows; } In debug mode, I found that the rows was still 0 and the event invoked after the the even of toggleEditing. It looks like that sectionInfo obtained from fetchedResultsController did not include the new entity object inserted. Not sure if I miss anything or steps? I am not sure how it works: to get the fetcedResultsController notified or reflect the change when a new entity is inserted into the current managed object context?

  • Is Appcelerator Titanium now banned on the iPhone?

    - by altuzar
    This question has been answered quite clearly for MonoTouch here: http://stackoverflow.com/questions/2604033/is-monotouch-now-banned-on-the-iphone But what about Appcelerator Titanium? The new TOS from Apple and their iPhone 4 OS: 3.3.1 — Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs. Applications must be originally written in Objective-C, C, C++, or JavaScript as executed by the iPhone OS WebKit engine, and only code written in C, C++, and Objective-C may compile and directly link against the Documented APIs (e.g., Applications that link to Documented APIs through an intermediary translation or compatibility layer or tool are prohibited). Titanium uses JavaScript but is not executed be the iPhone OS WebKit engine directly. In their Developer blog, Jeff Haynie says Titanium is on the clear, but I don't know if they are in denial. It’s our belief that we are fully in compliance with iPhone OS 4.0 ToS as we interpret them. I haven't found any official word by Apple, only opinions. And I'm quite confussed. I'm not writing another line of code for my App until... you know.

  • Linq to SQL and concurrency with Rob Conery repository pattern

    - by David Hall
    I have implemented a DAL using Rob Conery's spin on the repository pattern (from the MVC Storefront project) where I map database objects to domain objects using Linq and use Linq to SQL to actually get the data. This is all working wonderfully giving me the full control over the shape of my domain objects that I want, but I have hit a problem with concurrency that I thought I'd ask about here. I have concurrency working but the solution feels like it might be wrong (just one of those gitchy feelings). The basic pattern is: private MyDataContext _datacontext private Table _tasks; public Repository(MyDataContext datacontext) { _dataContext = datacontext; } public void GetTasks() { _tasks = from t in _dataContext.Tasks; return from t in _tasks select new Domain.Task { Name = t.Name, Id = t.TaskId, Description = t.Description }; } public void SaveTask(Domain.Task task) { Task dbTask = null; // Logic for new tasks omitted... dbTask = (from t in _tasks where t.TaskId == task.Id select t).SingleOrDefault(); dbTask.Description = task.Description, dbTask.Name = task.Name, _dataContext.SubmitChanges(); } So with that implementation I've lost concurrency tracking because of the mapping to the domain task. I get it back by storing the private Table which is my datacontext list of tasks at the time of getting the original task. I then update the tasks from this stored Table and save what I've updated This is working - I get change conflict exceptions raised when there are concurrency violations, just as I want. However, it just screams to me that I've missed a trick. Is there a better way of doing this? I've looked at the .Attach method on the datacontext but that appears to require storing the original version in a similar way to what I'm already doing. I also know that I could avoid all this by doing away with the domain objects and letting the Linq to SQL generated objects all the way up my stack - but I dislike that just as much as I dislike the way I'm handling concurrency.

  • Using RabbitMQ (Java client), is there a way to determine if network connection is closed during con

    - by MItch Branting
    I'm using RabbitMQ on RHEL 5.3 using the Java client. I have 2 nodes (machines). Node1 is consuming messages from a queue on Node2 using the Java helper class QueueingConsumer. QueueingConsumer consumer = new QueueingConsumer(channel); channel.basicConsume("MyQueueOnNode2", noAck, consumer); while (true) { QueueingConsumer.Delivery delivery = consumer.nextDelivery(); ... Process message - delivery.getBody() } If the interface is brought down on Node1 or Node2 (e.g. ifconfig eth1 down), the client (above) never knows the network isn't there anymore. Does RabbitMQ provide some type of configuration on the Java client that can be used to determine if the connection has gone away. Shutting down the RabbitMQ server on Node2 will trigger a ShutdownSignalException, which can be caught and the app can go into a reconnect loop. But bringing down the interface doesn't cause any type of exception to happen, so the code will be waiting forever on consumer.nextDelivery(). I've also tried using the timeout version of this call. e.g. QueueingConsumer consumer = new QueueingConsumer(channel); channel.basicConsume("MyQueueOnNode2", noAck, consumer); int timeout_ms = 30000; while (true) { QueueingConsumer.Delivery delivery = consumer.nextDelivery(timeout_ms); if (delivery == null) { if (channel.isOpen() == false) // Seems to always return true { throw new ShutdownSignalException(); } } else { ... Process message - delivery.getBody() } } but appears that this always returns true (even though the interface is down). I assume registering for the ShutdownListener on the connection will yield the same results, but haven't tried that yet. Is there a way to configure some sort of heartbeat, or do you just have to write custom lease logic (e.g. "I'm here now") in order to get this to work?

  • How to populate Java (web) application with initial data using Spring/JPA/Hibernate

    - by Tuukka Mustonen
    I want to setup my database with initial data programmatically. I want to populate my database for development runs, not for testing runs (it's easy). The product is built on top of Spring and JPA/Hibernate. Developer checks out the project Developer runs command/script to setup database with initial data Developer starts application (server) and begins developing/testing then: Developer runs command/script to flush the database and set it up with new initial data because database structures or the initial data bundle were changed What I want is to setup my environment by required parts in order to call my DAOs and insert new objects into database. I do not want to create initial data sets in raw SQL, XML, take dumps of database or whatever. I want to programmatically create objects and persist them in database as I would in normal application logic. One way to accomplish this would be to start up my application normally and run a special servlet that does the initialization. But is that really the way to go? I would love to execute the initial data setup as Maven task and I don't know how to do that if I take the servlet approach. There is somewhat similar question. I took a quick glance at the suggested DBUnit and Unitils. But they seem to be heavily focused in setting up testing environments, which is not what I want here. DBUnit does initial data population, but only using xml/csv fixtures, which is not what I'm after here. Then, Maven has SQL plugin, but I don't want to handle raw SQL. Maven also has Hibernate plugin, but it seems to help only in Hibernate configuration and table schema creation (not in populating db with data). How to do this?

  • Write-only collections in MongoDB

    - by rcoder
    I'm currently using MongoDB to record application logs, and while I'm quite happy with both the performance and with being able to dump arbitrary structured data into log records, I'm troubled by the mutability of log records once stored. In a traditional database, I would structure the grants for my log tables such that the application user had INSERT and SELECT privileges, but not UPDATE or DELETE. Similarly, in CouchDB, I could write a update validator function that rejected all attempts to modify an existing document. However, I've been unable to find a way to restrict operations on a MongoDB database or collection beyond the three access levels (no access, read-only, "god mode") documented in the security topic on the MongoDB wiki. Has anyone else deployed MongoDB as a document store in a setting where immutability (or at least change tracking) for documents was a requirement? What tricks or techniques did you use to ensure that poorly-written or malicious application code could not modify or destroy existing log records? Do I need to wrap my MongoDB logging in a service layer that enforces the write-only policy, or can I use some combination of configuration, query hacking, and replication to ensure a consistent, audit-able record is maintained?

  • In Asp.Net MVC 2 is there a better way to return 401 status codes without getting an auth redirect

    - by Greg Roberts
    I have a portion of my site that has a lightweight xml/json REST API. Most of my site is behind forms auth but only some of my API actions require authentication. I have a custom AuthorizeAttribute for my API that I use to check for certain permissions and when it fails it results in a 401. All is good, except since I'm using forms auth, Asp.net conveniently converts that into a 302 redirect to my login page. I've seen some previous questions that seem a bit hackish to either return a 403 instead or to put some logic in the global.asax protected void Application_EndRequest() that will essentially convert 302 to 401 where it meets whatever criteria. Previous Question Previous Question 2 What I'm doing now is sort of like one of the questions, but instead of checking the Application_EndRequest() for a 302 I make my authorize attribute return 666 which indicates to me that I need to set this to a 401. Here is my code: protected void Application_EndRequest() { if (Context.Response.StatusCode == MyAuthAttribute.AUTHORIZATION_FAILED_STATUS) { //check for 666 - status code of hidden 401 Context.Response.StatusCode = 401; } } Even though this works, my question is there something in Asp.net MVC 2 that would prevent me from having to do this? Or, in general is there a better way? I would think this would come up a lot for anyone doing REST api's or just people that do ajax requests in their controllers. The last thing you want is to do a request and get the content of a login page instead of json.

  • MVC2 Apps (and others) sharing WCF services and authentication

    - by stupid-phil
    Hi, I've seen several similar scenarios explained here but not my particular one. I wonder if someone could tell me which direction to go in? I am developing two (and more later) MVC2 apps. There will also be another (thicker) client later on (WPF or Silverlight, TBD). These all need to share the same authentication. For the MVC2 apps they (preferably) need to be single log on - ie if a user logs in to one MVC2 app, they should be authorised on the other, as long as the cookie hasn't timed out. Forms authentication is to be used. All the apps need to use common business functionality and perform db access via a common WCF Service App. It would be nice (I think) if the WCF is not publicly accessible (ie blocked behind FW). The thicker client could use an additional service layer to access the Common WCF App. What this should look like is: MVCApp1 - WCFAppCommon MVCApp2 - WCFAppCommon ThickClient - WCFApp2 - WCFAppCommon Is it possible to carry out all the authentication/authorization in the WCFAppCommon? Otherwise I think I'll have to repeat all the security logic in the MVCApps and WCFApp2, whereas, to me, it seems to sit naturally in WCFAppCommon. On the otherhand, it seems if I authenticate/authorize in WCFAppCommon, I wouldn't be able to use Forms Authentication. Where I've seen possible solutions (that I haven't tried yet) they seem much more complex than Forms Authentication and a single DB. Any help appreciated, Phil

  • How to play non buffered .wav with MediaStreamSource implementation in Silverlight 4?

    - by kyrisu
    Background I'm trying to stream a wave file in Silverlight 4 using MediaStreamSource implementation found here. The problem is I want to play the file while it's still buffering, or at least give user some visual feedback while it's buffering. For now my code looks like that: private void button1_Click(object sender, RoutedEventArgs e) { HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(new Uri(App.Current.Host.Source, "../test.wav")); //request.ContentType = "audio/x-wav"; request.AllowReadStreamBuffering = false; request.BeginGetResponse(new AsyncCallback(RequestCallback), request); } private void RequestCallback(IAsyncResult ar) { this.Dispatcher.BeginInvoke(delegate() { HttpWebRequest request = (HttpWebRequest)ar.AsyncState; HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(ar); WaveMediaStreamSource wavMss = new WaveMediaStreamSource(response.GetResponseStream()); try { me.SetSource(wavMss); } catch (InvalidOperationException) { // This file is not valid } me.Play(); }); } The problem is that after settings request.AllowREadStreamBuffer to false the stream does not support seeking and the above mentioned implementation throws an exception (keep in mind I've put some of the position setting logic into if(stream.CanSeek) block): Read is not supported on the main thread when buffering is disabled Question Is there a way to play wav stream without buffering it in advance?

  • Synchronizing Asynchronous request handlers in Silverlight environment

    - by Eric Lifka
    For our senior design project my group is making a Silverlight application that utilizes graph theory concepts and stores the data in a database on the back end. We have a situation where we add a link between two nodes in the graph and upon doing so we run analysis to re-categorize our clusters of nodes. The problem is that this re-categorization is quite complex and involves multiple queries and updates to the database so if multiple instances of it run at once it quickly garbles data and breaks (by trying to re-insert already used primary keys). Essentially it's not thread safe, and we're trying to make it safe, and that's where we're failing and need help :). The create link function looks like this: private Semaphore dblock = new Semaphore(1, 1); // This function is on our service reference and gets called // by the client code. public int addNeed(int nodeOne, int nodeTwo) { dblock.WaitOne(); submitNewNeed(createNewNeed(nodeOne, nodeTwo)); verifyClusters(nodeOne, nodeTwo); dblock.Release(); return 0; } private void verifyClusters(int nodeOne, int nodeTwo) { // Run analysis of nodeOne and nodeTwo in graph } All copies of addNeed should wait for the first one that comes in to finish before another can execute. But instead they all seem to be running and conflicting with each other in the verifyClusters method. One solution would be to force our front end calls to be made synchronously. And in fact, when we do that everything works fine, so the code logic isn't broken. But when it's launched our application will be deployed within a business setting and used by internal IT staff (or at least that's the plan) so we'll have the same problem. We can't force all clients to submit data at different times, so we really need to get it synchronized on the back end. Thanks for any help you can give, I'd be glad to supply any additional information that you could need!

  • WiX: Prevent 32-bit installer from running on 64-bit Windows

    - by Tom the Junglist
    Hi everyone, Due to user confusion, our app requires separate installers for 32-bit and 64-bit versions of Windows. While the 32-bit installer runs fine on win64, it has the potential to create support headaches and we would like to prevent this from happening. I want to prevent the 32-bit MSI installer from running on 64-bit Windows machines. To that end I have the following condition: <Condition Message="You are attempting to run the 32-bit installer on a 64-bit version of Windows."> <![CDATA[Msix64 AND (NOT Win64)]]> </Condition> With the Win64 defined like this: <?if $(var.Platform) = "x64"?> <?define PlatformString = "64-bit"?> <?define Win64 ?> <?else?> <?define PlatformString = "32-bit"?> <?endif?> Thing is, I can't get this check to work right. Either it fires all the time, or none of the time. The goal is to check presence of the run-time msix64 variable against the compile-time Win64 variable and throw an error if these don't line up, but the logic is not working how I intend it to. Has anyone come up with a better solution? Thanks! Tom
