  • DotNetOpenAuth OpenID on ISA 2006 Reverse Proxy problem

    - by userb00
    I am trying to host my site that uses DotNetOpenAuth (OpenID) behind ISA 2006 (reverse proxy), and after it authenticated with a provider (such as Google), and it returns with a URL with %253A in the URL. However, ISA HTTP filter rejects the request. What I need to do is, on ISA web publishing rule, right click config HTTP policy properties uncheck "Verify Normalization" and it worked. Is this a problem on ISA 2006 generally? Are other firewalls having similar problems? Or, is it an OpenID or DotNetOpenAuth issue? Is it safe to disable Normalization checking on ISA? According to MSDN, quote "Web servers receive requests that are URL encoded. This means that certain characters may be replaced with a percent sign (%) followed by a particular number. For example, %20 corresponds to a space, so a request for http://myserver/My%20Dir/My%20File.htm is the same as a request for http://myserver/My Dir/My File.htm. Normalization is the process of decoding URL-encoded requests. Because the % can be URL encoded, an attacker can submit a carefully crafted request to a server that is basically double-encoded. If this occurs, Internet Information Services (IIS) may accept a request that it would otherwise reject as not valid. When you select Verify Normalization, the HTTP filter normalizes the URL two times. If the URL after the first normalization is different from the URL after the second normalization, the filter rejects the request. This prevents attacks that rely on double-encoded requests. Note that while we recommend that you use the Verify Normalization function, it may also block legitimate requests that contain a %."

  • How do i use signtool.exe correctly in hudson running as a service?

    - by Tim
    I just purchased a code signing cert (MS authenticode) from THAWTE and have installed it apparently on my build machine. I am logged in as a user and when I open a cmd prompt I can sign EXEs using the cert with signtool.exe. Unfortunately this same command line does not work in the hudson process that is running on the machine. the error message I get is: SignTool Error: No certificates were found that met all the given criteria. I presume this is because the hudson service is running under a different account than the account that I ran signtool.exe from and from the account I used to get the cert from thawte. So, my question is: How do I fix this problem? I thought i was going to download a file from thawte, but instead it just used IE somehow to install the cert in the user's cache magically. I probably want to export (or whatever the correct term is) to a file that I can store/save or use on any other machine. How do i do that and how do I call signtool correctly with either the file or the cert from another user in the system/services account?

  • Programatically send SMS to email using Verizon Motorola Droid on Android

    - by Dave
    Hi, I was wondering if anyone knew the proper way to send an SMS message to an e-mail address using Verizon's CDMA Motorola Droid phone. The internal messaging application appears to automagically do this. While 3rd party applications like SMSPopup don't seem to be able to properly reply to e-mail addresses unless you compose the message inside the messaging application. When the internal messaging application sends a SMS message there's a corresponding 'RIL_REQUEST_CDMA_SEND_SMS' entry in the logcat (adb logcat -b radio). When you send a SMS to an e-mail address it prints the same thing, so behind the scenes it looks as though it is sending an sms. The interesting thing is that if you look at the content provider sent box the messages are addressed to various 1270XX-XXX-XXXX numbers. On other services you can send e-mail addresses by sending a SMS to a predefined short sms number. And then formatting your SMS as emailaddress subject message i.e. http://en.wikipedia.org/wiki/SMS_gateway#Carrier-Provided_SMS_to_E-Mail_Gateways For example, using T-mobile's number (500) you can send a SMS to an e-mail using the following: SmsManager smsMgr = SmsManager.getDefault(); smsMgr.sendTextMessage("500", null, "[email protected] message sent to an e-mail address from a SMS", null, null); Does anyone know if It is possible to programatically send SMS to email messages from a CDMA Android phone? Does Verizon actually send your replies as SMS messages or are they actually sent as MMS or normal http email messages? Any ideas about how to intercept what the raw message being sent to see what's going on? It might be possible that Verizon somehow generates a fake number temporarily tied to an e-mail address (since repeated messages are not sent to the same number). But, that seems pretty heavy handed. Thanks!

  • WCF Service Client Lifetime

    - by Burt
    I have a WPF appliction that uses WCF services to make calls to the server. I use this property in my code to access the service private static IProjectWcfService ProjectService { get { _projectServiceFactory = new ProjectWcfServiceFactory(); return _projectServiceFactory.Create(); } } The Create on the factory looks like this public IProjectWcfService Create() { _serviceClient = new ProjectWcfServiceClient(); //ToDo: Need some way of saving username and password _serviceClient.ClientCredentials.UserName.UserName = "Brendan"; _serviceClient.ClientCredentials.UserName.Password = "password"; return _serviceClient; } To access the service methods I use somethingn like the following. ProjectService.Save(dto); Is this a good approach for what I am trying to do? I am getting an errorthat I can't track down that I think may be realted to having too many service client connections open (is this possible?) notice I never close the service client or reuse it. What would the best practice for WCF service client's be for WPF calling? Thanks in advance...

  • Moq and accessing called parameters

    - by lozzar
    I've just started to implement unit tests (using xUnit and Moq) on an already established project of mine. The project extensively uses dependency injection via the unity container. I have two services A and B. Service A is the one being tested in this case. Service A calls B and gives it a delegate to an internal function. This 'callback' is used to notify A when a message has been received that it must handle. Hence A calls (where b is an instance of service B): b.RegisterHandler(Guid id, Action<byte[]> messageHandler); In order to test service A, I need to be able to call messageHandler, as this is the only way it currently accepts messages. Can this be done using Moq? ie. Can I mock service B, such that when RegisterHandler is called, the value of messageHandler is passed out to my test? Or do I need to redesign this? Are there any design patterns I should be using in this case? Does anyone know of any good resources on this kind of design?

  • Apache2: mod_wsgi or mod_python, which one is better?

    - by Algorist
    Hi, I am planning to write web service in python. But, I found wsgi also does the similar thing. Which one can be preferred? Thank you Bala Update I am still confused. Please help. Better in my sense means: 1. Bug will be fixed periodically. 2. Chosen by most developers. 3. Additional features like authentication tokens like AWS, can be supported out of the box. 4. No strong dependency on version.( I see that wsgi requires python 2.6) 5. All python libraries will work out of the box. 6. Scalable in the future. 7. Future upgrade don't cause any issues. With my limited experience, I want these features. There might be some I might be missing. Thanks Bala Update I am sorry for all the confusion caused. I just want to expose a restful web services in python language. Is there a good framework?

  • ACL architechture for a Software As a service in Spring 3.0

    - by geoaxis
    I am making a software as a service using Spring 3.0 (Spring MVC, Spring Security, Spring Roo, Hibernate) I have to come up with a flexible access control list mechanism.I have three different kinds of users System (who can do any thing to the system, includes admin and internal daemons) Operations (who can add and delete users, organizations, and do maintenance work on behalf of users and organizations) End Users (they belong to one or more organization, for each organization, the user can have one or more roles, like being organization admin, or organization read-only member) (role like orgadmin can also add users for that organization) Now my question is, how should i model the entity of User? If I just take the End User, it can belong to one or more organizations, so each user can contain a set of references to its organizations. But how do we model the users role for each organization, So for example User UX belongs to organizations og1, og2 and og3, and for og1 he is both orgadmin, and org-read-only-user, where as for og2 he is only orgadmin and for og3 he is only org-read-only-user I have the possibility of making each user belong to one organization alone, but that's making the system bounded and I don't like that idea (although i would still satisfy the requirement) If you have a better extensible ACL architecture, please suggest it. Since its a software as a service, one would expect that alot of different organizations would be part if the same system. I had one concern that it is not a good idea to keep og1 and og2 data on the same DB (if og1 decides to spawn a 100 reports on the system, og2 should not suffer) But that is some thing advanced for now and is not directly related to ACL but to the physical distribution of data and setup of services based on those ACLs This is a community Wiki question, please correct any thing which you wish to do so. Thanks

  • Using YQL multi-query & XPath to parse HTML, how to escape nested quotes?

    - by Tivac
    The title is more complicated than it has to be, here's the problem query. SELECT * FROM query.multi WHERE queries=" SELECT * FROM html WHERE url='http://www.stumbleupon.com/url/http://www.guildwars2.com' AND xpath='//li[@class=\"listLi\"]/div[@class=\"views\"]/a/span'; SELECT * FROM xml WHERE url='http://services.digg.com/1.0/endpoint?method=story.getAll&link=http://www.guildwars2.com'; SELECT * FROM json WHERE url='http://api.tweetmeme.com/url_info.json?url=http://www.guildwars2.com'; SELECT * FROM xml WHERE url='http://api.facebook.com/restserver.php?method=links.getStats&urls=http://www.guildwars2.com'; SELECT * FROM json WHERE url='http://www.reddit.com/button_info.json?url=http://www.guildwars2.com'" Specifically this line, xpath='//li[@class=\"listLi\"]/div[@class=\"views\"]/a/span' It's problematic because of the quoting, I have to nest them three levels deep and I've run out of quote characters to use. I've tried the following variations without success: //no attribute quoting xpath='//li[@class=listLi]/div[@class=views]/a/span' //try to quote attribute w/ backslash & single quote xpath='//li[@class=\'listLi\']/div[@class=\'views\']/a/span' //try to quote attribute w/ backslash & double quote xpath='//li[@class=\"listLi\"]/div[@class=\"views\"]/a/span' //try to quote attribute with double single quotes, like SQL xpath='//li[@class=''listLi'']/div[@class=''views'']/a/span' //try to quote attribute with double double quotes, like SQL xpath='//li[@class=""listLi""]/div[@class=""views""]/a/span' //try to quote attribute with quote entities xpath='//li[@class=&quot;listLi&quot;]/div[@class=&quot;views&quot;]/a/span' //try to surround XPath with backslash & double quote xpath=\"//li[@class='listLi']/div[@class='views']/a/span\" //try to surround XPath with double double quote xpath=""//li[@class='listLi']/div[@class='views']/a/span"" All without success. I don't see much out there about escaping XPath strings but everything I've found seems to be variations on using concat (which won't help because neither ' nor " are available) or html entities. Not using quotes for the attributes doesn't throw an error but fails because it's not the actual XPath string I need. I don't see anything in the YQL docs about how to handle escaping. I'm aware of how edge-casey this is but was hoping they'd have some sort of escaping guide.

  • scripsharp reference web service / strongly type to results model

    - by user175528
    With scriptsharp (script#) is it possible to get strong typing when calling a service defined in my web app? The only way I can see is to: 1 - use linked / shared files to shadow copy my results classes / domain models across into my script# lib 2 - replicate my model across in the script# lib and use automapper to validate? 3 - use some .tt to code gen? also, even if I can do this, how do I get around the auto camel-casing script# does, when my service result (asmx) wont do this? (so my JSON response will comback as UserMessage, script# will have changed that to userMessage) basically, what I am looking to use script# to achieve is better compile time support against our domain model when calling and processing services in javascript, so something like this: Scriptlet public static class MyScriptlet { public static void Main() { MyService.Service1("hello", ProcessResponse);} public static void ProcessResponse(MyService.Service1ResponseData resp) { jQuery.Select('#Message').Text(resp.UserMessage); jQuery.Select('#Detail').Text(resp.UserDetail); } Service (in our web app) public class MyService { public class Service1ResponseData { public string UserMessage {get;set;} public string UserDetail {get;set;} } public Service1ResponseData Service1(string user) { return new Service1ResponseData() { UserMessage:"hi",UserDetail:"some text"}; } }

  • WCF, ASMX Basic HTTP binding and IIS

    - by Brennan Mann
    Hello, I have been doing a lot of work with WCF "self" hosted applications. I recently was requested to write a web service where the calling client was a Linux based program named "WGET". I would like to use WCF instead of a traditional ASMX web service. The web service is returning a standard XML response. I am not sure of the underlining details between the two technologies but I know WCF is the proper route. I created a WCF service to be hosted in IIS ( using basicHttpBinding). 1.) Did classic ASMX web services ( standard HTTP POST/GET) use SOAP to return responses? I created an class from XSD for the web service response. What is really going on behind the scenes? Is there just special XML HTTP headers that know how to handle to response? Is the response not wrapped in SOAP? The traditional ASMX web service worked perfectly with the class I generated using the .Net "XSD" program. 2.) I want to use WCF for this service. Will using basicHttpBinding work? As I have read, that is the correct binding to use for ASMX clients. Does this use SOAP, standard HTTP headers, or something else? 3.) This is a dumb question because I have not done a lot of web service programming. I noticed on the ASMX default landing page there were examples for responses and code to invoke the functionality. When I create the same service using WCF, I had to create a client application to perform these tasks. Is there a way to expose the WCF endpoint like a classic ASMX service or is the WSDL the only route? As always, I really appreciate the feedback. Thanks, Brennan

  • IIS8 Asp.net State service remote connection failure

    - by maxisam
    Recently we upgrade our web server to windows server 2012 with IIS8. We have this issue when users try to connect the asp.net state service to this web server remotely. It always popup Unable to make the session state request to the session state server. Please ensure that the ASP.NET State service is started and that the client and server ports are the same. If the server is on a remote machine, please ensure that it accepts remote requests by checking the value of HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\aspnet_state\Parameters\AllowRemoteConnection. If the server is on the local machine, and if the before mentioned registry value does not exist or is set to 0, then the state server connection string must use either 'localhost' or '127.0.0.1' as the server name. In IIS7 / 7.5 we use the same way and it works fine. As long as the state service is running and firewall is set properly, we don't have any problem. However, in IIS8 it doesn't work. (We even turn off firewall to test it) Thanks for helping.

  • JAXB, BigDecimal or double?

    - by Alex
    I working on different web-services, and I always use WSDL First. JAXB generates for a Type like: <xsd:simpleType name="CurrencyFormatTyp"> <xsd:restriction base="xsd:decimal"> <xsd:totalDigits value="13"/> <xsd:fractionDigits value="2"/> <xsd:minInclusive value="0.01"/> </xsd:restriction> </xsd:simpleType> a Java binding type BigDecimal (as it's mentioned in JAXB specification). When I then do some simple arithmetic operation with values of the type double (which are stored in a database and mapped via hibernate to the type double) I run into trouble. <ns5:charge>0.200000000000000011102230246251565404236316680908203125</ns5:charge> <ns5:addcharge>0.0360000000000000042188474935755948536098003387451171875</ns5:addcharge> <ns5:tax>0.047199999999999998900879205621095024980604648590087890625</ns5:tax> <ns5:totalextax>0.2360000000000000153210777398271602578461170196533203125</ns5:totalextax> What would be the right way? Convert all my values into double (JAXB binding from BigDecimal to double) Hibernate mapping double to Bigdecimal and do all my arithmetic operations in one object type.

  • Is it possible to handle User Defined Exception using JAX WS Dispatch API ?

    - by snowflake
    Hello, I'm performing dynamic webservices call using following code snippet: JAXBContext jc = getJAXBContext(requestClass, responseClass, jaxbContextExtraClasses); Dispatch<Object> dispatch = service.createDispatch(portQName, jc, Service.Mode.PAYLOAD); Object requestValue = getRequestValue(requestClass, pOrderedParameters); JAXBElement<?> request = new JAXBElement(new QName(serviceQNameStr, pOperationName), requestValue.getClass(), null, requestValue); Object tmpResponse = dispatch.invoke(request); Invocation works perfectly, except if I add a user defined exception on the service (a basic UserException extends java.lang.Exception). First I get: javax.xml.bind.UnmarshalException: unexpected element (uri:"http://schemas.xmlsoap.org/soap/envelope/", local:"Fault"). Expected elements are <{http://my.namespace/}myMethod,<{http://my.namespace/}myResponse Then I added the UserException_Exception JAX-WS generated type to my JAXB Context, and then get: Caused by: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions java.lang.StackTraceElement does not have a no-arg default constructor. this problem is related to the following location: at java.lang.StackTraceElement at public java.lang.StackTraceElement[] java.lang.Throwable.getStackTrace() at java.lang.Throwable at java.lang.Exception Only solution available I found are: dispatch directly a Soap message and handle Soap fault directly (this is the way Jboss JAX-WS implementation performs a standard JAX-WS call using services interfaces). This is not an available solution for me, I want to use a high level implementation (the more I get close to Soap message the less dynamic my code can be) usage of JAXBRIContext.ANNOTATION_READER, which is implementation specific and not an available solution for me, in order to annotate annotates java.lang.Exception as @XmlTransient The service with a user defined exception performs well using the JAX-WS generated standard client stubs and using a tool such Soap UI. Problem occurs in deserialization of the message when I have no user defined exception artifact in the JAXB context, and during invocation when I add those non JAXB compatible artifacts in the JAXB context. I'm usign Jboss WS webservice stack within Jboss 4.2.3.GA Any elegant solution to this problem is welcomed !

  • Debugging SQL Server Slowness: Same Database, Different Servers

    - by Craig Walker
    For a while now we've been having anecdotal slowness on our newly-minted (VMWare-based) SQL Server 2005 database servers. Recently the problem has come to a head and I've started looking for the root cause of the issue. Here's the weird part: on the stored procedure that I'm using as a performance test case, I get a 30x difference in the execution speed depending on which DB server I run it on. This is using the same database (mdf) and log (ldf) files, detached, copied, and reattached from the slow server to the fast one. This doesn't appear to be a (virtualized) hardware issue: he slow server has 4x the CPU capacity and 2x the memory as the fast one. As best as I can tell, the problem lies in the environment/configuration of the servers (either operating system or SQL Server installation). However, I've checked a bunch of variables (SQL Server config options, running services, disk fragmentation) and found nothing that has made a difference in testing. What things should I be looking at? What tools can I use to investigate why this is happening?

  • Error when instantiating .NET/COM interop class via classic ASP

    - by Lee D
    Hi all, I am having a problem when trying to instantiate a C# .NET class that's been exposed to COM in a classic ASP application. I've used tlbexp to generate a typelib and registered it in Component Services; now when trying to create the object as such: Server.CreateObject("The.Class.Name") I am getting the error: Server object error 'ASP 0177 : 80131534' Server.CreateObject Failed I've searched around online for information on this error, and found numerous discussions but no solution. The error code 0x80131534 apparently means "COR_E_TYPEINITIALIZATION, a type failed to initialize", which would suggest the problem would be in the constructor. The constructor of the class in question sets a private field to an instance of another class from the same assembly, and then reads some configuration settings from an XML file. This behaviour is unit tested and I've checked that the file exists; I can't see anything else that could be breaking in there. A few other points which may or may not be of use: A test .NET project referencing the DLL can instantiate the class just fine; however a test VB6 project referencing the TLB blows up with the same error. Both the DLL and the TLB are in the same location. This application is running locally, on Windows XP Professional SP3 and IIS 5.1. The .NET assembly is built with .NET Framework 2.0, although 3.5 is installed on the machine. I know other people who don't get this error on their builds, so I believe it may be something environmental. Any suggestions are welcome as I've been struggling to fix this for some time. Thanks in advance.

  • Stopping the service and the babysited application before uninstalling

    - by Viv Coco
    Hi all, I have a service MyService.exe that is babysitting my application MyApp.exe, meaning it starts the application when this one crashes or whatever. Basically when the service is stopped the application is stopped (by the service) and when the service is started the application is started by the service. In order to stop my service and by that my application when uninstalling I'm doing: <ServiceControl Id='MyServiceControl' Name='MyServiceForTest' Start='install' Stop='uninstall' Remove='uninstall'/> But when I want to uninstall everything I get the error message: "The setup must update files or services that cannot be updated while the system is running. If you choose to continue, a reboot will be required to complete the setup.". If I manually stop the service before running the uninstaller I don't get this msg as both my service and my application aren't then running anymore. In the log file I noticed that this happens in InstallValidate and I get this message b/c of MyApp.exe being running. I think what happens is: the uninstallers checks the running applications, it notices that the MyService.exe and MyApp.exe are both running, detects probably that the MyService.exe will be stopped by the uninstaller itself as instructed, but doesn't know about the MyApp.exe that this one will also be terminated once the service will be stopped so it will show the reboot-message. I can't just close MyApp.exe from uninstaller b/c the service will restart it again. How could I solve this problem so that the user won't need to reboot or to manually stop the service before doing an uninstall/upgrade? Also, I can't change MyService and MyApp code anymore so I will have to do this from the (un)installer only. TIA, Viv

  • Alternatives to decompiling MS Access MDE files

    - by booyaa
    I've been tasked with finding a suitable tool to decompile MDE files. The MDEs were created by staff who have since left (familar story eh?) and we do not have access to the originally MDB files. The reason we need access to the original code is that the data source is changing (the backend as well as some of the table and queries) and we need a way to update queries. An example of a change, in a SELECT statement where is the WHERE clause looks for zero as a string ("0") rather than an integer. I'm aware that unless you use the services of people like EverythingAccess.com its unlikely you will ever get the source code back. My main query is to ask for alternative methods to decompiling code. An example of the kinds of methods I'm thinking about is to spy on the traffic between the app the the ODBC DSN using tcpdump. I might then be able to write code to translate the data source queries between the old and new systems. Ideally I'd prefer a solution that is application centric rather than one that analyses all network traffic. I should add one caveat, no doubt most of you are thinking the best solution is to rewrite the code, based on its perceived functionality. This is the option we're not considering (at the moment).

  • Can't submit new object to WCF DataService because of Primary Key constraint

    - by Rob
    I've got a SQL database that uses Guid's for PK's and upon insert, it generates a NewId(). I have an EF data context setup pointing to that database with the primary keys setup with the Entity key:true, Setter:private and StoreGeneratedPattern:Identity because I want the DB to manage the keys and not have code set the PK property. I have an OData (System.Web.Data.Services.DataService) endpoint to access this data (just like: Hanselman did. I have another app that has a service reference to this service. Upon trying to create a new object from this reference (i.e. Product), the ProductId Primary Key is being defaulted to Guid.Empty when doing var serviceEntities = new ServiceEntities(serviceUri); //OData endpoint var product = new Product(); product.Name = "New Product"; serviceEntities.AddToProducts(product); serviceEntities.SaveChanges(); // error happens here When debugging, I look at the Product.ProductId property and it's set to Guid.Empty. When called SaveChanges, I do not want the ProductId field to be sent to the service. The response I get is: Error processing request stream. Property 'ProductId' is a read-only property and cannot be updated. Please make sure that this property is not present in the request payload. Is there a way to do this or what can I do to get this setup correctly and still have the DB generated the keys. Here is the same setup as the Product example above.

  • WCF InProcFactory error

    - by Terence Lewis
    I'm using IDesign's ServiceModelEx assembly to provide additional functionality over and above what's available in standard WCF. In particular I'm making use of InProcFactory to host some WCF services within my process using Named Pipes. However, my process also declares a TCP endpoint in its configuration file, which I host and open when the process starts. At some later point, when I try to host a second instance of this service using the InProcFactory through the named pipe (from a different service in the same process), for some reason it picks up the TCP endpoint in the configuration file and tries to re-host this endpoint, which throws an exception as the TCP port is already in use from the first hosting. Here is the relevant code from InProcFactory.cs in ServiceModelEx: static HostRecord GetHostRecord<S,I>() where I : class where S : class,I { HostRecord hostRecord; if(m_Hosts.ContainsKey(typeof(S))) { hostRecord = m_Hosts[typeof(S)]; } else { ServiceHost<S> host; if(m_Singletons.ContainsKey(typeof(S))) { S singleton = m_Singletons[typeof(S)] as S; Debug.Assert(singleton != null); host = new ServiceHost<S>(singleton,BaseAddress); } else { host = new ServiceHost<S>(BaseAddress); } string address = BaseAddress.ToString() + Guid.NewGuid().ToString(); hostRecord = new HostRecord(host,address); m_Hosts.Add(typeof(S),hostRecord); host.AddServiceEndpoint(typeof(I),Binding,address); if(m_Throttles.ContainsKey(typeof(S))) { host.SetThrottle(m_Throttles[typeof(S)]); } // This line fails because it tries to open two endpoints, instead of just the named-pipe one host.Open(); } return hostRecord; }

  • iOS iPad UIActionSheet Issue

    - by hart1994
    I am currently developing an application which needs an option to 'share' using multiple services; such as email, twitter. To to this, I have a UIBarButtonItem coded in and when touched, it triggers this: UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:@"" delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil]; [sheet addButtonWithTitle:@"Email"]; [sheet addButtonWithTitle:@"Tweet"]; [sheet addButtonWithTitle:@"Cancel"]; sheet.cancelButtonIndex = sheet.numberOfButtons-1; [sheet showFromRect:self.view.bounds inView:self.view animated:YES]; [sheet release]; In conjunction with this to detect which button is selected: clickedButtonAtIndex:(NSInteger)buttonIndex { if (buttonIndex == actionSheet.cancelButtonIndex) { return; } switch (buttonIndex) { case 0: { [self emailThis]; break; } case 1: { [self tweetThis]; break; } } This works a treat on the iPhone. But unfortunately it displays incorrectly on the iPad. It looks like it is trying to display the UIPopoverController, but it is positioned center of the navbar with practically no height. I have looked into using the UIPopoverController, but I cannot seem to find out how to use it with buttons. Is there anyway I can adapt the code above to properly display the buttons, as it's trying to already. Many thanks, Ryan PS: I'm new to objective-c/iOS coding, so please be specific. Thank you :)

  • Spell checker software

    - by Naren
    Hello Guys, I have been assigned a task to find a decent spell checker (UK English) preferably the free one for a project that we are doing. I have looked at Google AJAX API for this. The project contains some young person's (kids less than 18 years old) data which shouldn't allow exposing or storing outside the application boundaries. Google logs the data for research purpose that means Google owns the data whatever we send over the wire through Google API. Is this right? I fired an email to Google regarding the privacy of data and storage but they haven't come back. If you have some knowledge regarding this please share with me. At this point our servers might not have access to external entities that means we might not be able to use Web API for this over the wire. But it may change in the future. That means I have to find out some spell checker alternatives that can sit in our environment and do the job or an external APIs. Would you mind share your findings and knowledge in this regard. I would prefer free services but never know if you have some cracking spell checker for a few quid’s then I don't mind recommending to the project board. Technology using ASP.NET 3.5/4.0, MVC, jQuery, SQL Sever 2008 etc Cheers, Naren

  • Limit the number of service calls in a RESTful application

    - by Slavo
    Imagine some kind of a banking application, with a screen to create accounts. Each Account has a Currency and a Bank as a property, Currency being a separate class, as well as Bank. The code might look something like this: public class Account { public Currency Currency { get; set; } public Bank Bank { get; set; } } public class Currency { public string Code { get; set; } public string Name { get; set; } } public class Bank { public string Name { get; set; } public string Country { get; set; } } According to the REST design principles, each resource in the application should have its own service, and each service should have methods that map nicely to the HTTP verbs. So in our case, we have an AccountService, CurrencyService and BankService. In the screen for creating an account, we have some UI to select the bank from a list of banks, and to select a currency from a list of currencies. Imagine it is a web application, and those lists are dropdowns. This means that one dropdown is populated from the CurrencyService and one from the BankService. What this means is that when we open the screen for creating an account, we need to make two service calls to two different services. If that screen is not by itself on a page, there might be more service calls from the same page, impacting the performance. Is this normal in such an application? If not, how can it be avoided? How can the design be modified without going away from REST?
