  • How do you determine with CLLocationManager when a user denies access to location services?

    - by Brennan
    With CLLocationManager I can use the following code to determine if I can access location services on the device. This is the master setting for all apps and can be turned on and off. if (self.locationManager.locationServicesEnabled) { [self.locationManager startUpdatingLocation]; } But a user can deny access to an individual app and in order to not execute the code to use the location manager I need to know if the user approved access to location services for this specific app. I saw that at one point there was a property called locationServicesApproved which appears it would indicate if the user approved access to location services in this app. But it was removed in 2008. Source: http://trailsinthesand.com/apple-removes-notifications-from-iphone-sdk-beta-4/ It appears that there is no way to determine if the user approved access to location services but that seems to be a big hole in the SDK. Is this feature in the SDK elsewhere? What can I do to determine if the user has approved access to location services for the current app?

  • How do you search between two columns using a parameter and a case when statement? SQL Server

    - by Kip Birgen
    I would like to search between to columns in a s query or a table depending on the variable on a paramenter e.g Declare @SelectAll as interger Set @SelectAll = 1 Declare @Column as interger Select mt.Column1, mtColumn2 From MyTable as mt Where Case When @SelectAll = 1 Then mt.Column1 IN(@Column) and mt.Column2 (' Selecting all") When @SelectAll = 1 Then mt.Column2 IN(@Column) and mt.Column1 (' Selecting all") End The purpose of this query is to allow the user to search between the column they choose. Further more the use of parameter is for the purposes of writing reporting services reports.

  • should I ever put a major version number into a C#/Java namespace?

    - by Andrew Patterson
    I am designing a set of 'service' layer objects (data objects and interface definitions) for a WCF web service (that will be consumed by third party clients i.e. not in-house, so outside my direct control). I know that I am not going to get the interface definition exactly right - and am wanting to prepare for the time when I know that I will have to introduce a breaking set of new data objects. However, the reality of the world I am in is that I will also need to run my first version simultaneously for quite a while. The first version of my service will have URL of http://host/app/v1service.svc and when the times comes by new version will live at http://host/app/v2service.svc However, when it comes to the data objects and interfaces, I am toying with putting the 'major' version of the interface number into the actual namespace of the classes. namespace Company.Product.V1 { [DataContract(Namespace = "company-product-v1")] public class Widget { [DataMember] string widgetName; } public interface IFunction { Widget GetWidgetData(int code); } } When the time comes for a fundamental change to the service, I will introduce some classes like namespace Company.Product.V2 { [DataContract(Namespace = "company-product-v2")] public class Widget { [DataMember] int widgetCode; [DataMember] int widgetExpiry; } public interface IFunction { Widget GetWidgetData(int code); } } The advantages as I see it are that I will be able to have a single set of code serving both interface versions, sharing functionality where possible. This is because I will be able to reference both interface versions as a distinct set of C# objects. Similarly, clients may use both interface versions simultaneously, perhaps using V1.Widget in some legacy code whilst new bits move on to V2.Widget. Can anyone tell why this is a stupid idea? I have a nagging feeling that this is a bit smelly.. notes: I am obviously not proposing every single new version of the service would be in a new namespace. Presumably I will do as many non-breaking interface changes as possible, but I know that I will hit a point where all the data modelling will probably need a significant rewrite. I understand assembly versioning etc but I think this question is tangential to that type of versioning. But I could be wrong.

  • WSE 3.0 cookies support?

    - by aloneguid
    Hi, I'm trying to call a web service with WSE 3.0 which uses cookies for authentication. With standard SoapHttpClientProtocol, I could assign my CookieContainer to a request. However, WSE 3.0 web services does not directly or indirectly inherit from it. How can I set cookies to WSE 3.0 request?

  • A Python Wrapper for Shutterfly. Uploading an Image

    - by iJames
    I'm working on a Django app in which I want to order prints through Shutterfly's Open API: http://www.shutterfly.com/documentation/start.sfly So far I've been able to build the appropriate POSTs and GETs using the modules and suggested code snippets including httplib, httplib2, urllib, urllib2, mimetype, etc. But I'm stuck on the image uploading when placing an order (the ordering process is not the same process as uploading images to albums which I haven't tried.) From what I can tell, I'm supposed to basically create the multipart form data by concatenating the HTTP request body together with the binary data of the image. I take the strings: --myuniqueboundary1273149960.175.1 Content-Disposition: form-data; name="AuthenticationID" auniqueauthenticationid --myuniqueboundary1273149960.175.1 Content-Disposition: file; name="Image.Data"; filename="1_41_orig.jpg" Content-Type: image/jpeg and I put this data into it and end with the final boundary: ...\xb5|\xf88\x1dj\t@\xd9\'\x1f\xc6j\x88{\x8a\xc0\x18\x8eGaJG\x03\xe9J-\xd8\x96[\x91T\xc3\x0eTu\xf4\xaa\xa5Ty\x80\x01\x8c\x9f\xe9Z\xad\x8cg\xba# g\x18\xe2\xaa:\x829\x02\xb4["\x17Q\xe7\x801\xea?\xad7j\xfd\xa2\xdf\x81\xd2\x84D\xb6)\xa8\xcb\xc8O\\\x9a\xaf(\x1cqM\x98\x8d*\xb8\'h\xc8+\x8e:u\xaa\xf3*\x9b\x95\x05F8\xedN%\xcb\xe1B2\xa9~Tw\xedF\xc4\xfe\xe8\xfc\xa9\x983\xff\xd9... That ends up making it look like this (when I use print to debug): ... --myuniqueboundary1273149960.175.1 Content-Disposition: file; name="Image.Data"; filename="1_41_orig.jpg" Content-Type: image/jpeg ????q?ExifMM* ? ??(1?2?<??i?b?NIKON CORPORATIONNIKON D40HHQuickTime 7.62009:02:17 13:05:25Mac OS X 10.5.6%??????"?'??0220?????? ???? ? ?|_???,b???50??5 ... --myuniqueboundary1273149960.175.1-- My code for grabbing the binary data is pretty much this: filedata = open('myjpegfile.jpeg','rb').read() Which I then add to the rest of the body. I've see something like this code everywhere. I'm then using this to post the full request (with the headers too): response = urllib2.urlopen(request).read() This seems to me to be the standard way that form POSTS with files happens. Am I missing something here? At some point I might be able to make this into a library worth posting up on github, but this problem has stopped me cold in my tracks. Thanks for any insight!

  • Hosting a WCF Service Lib through a Windows service get a System.InvalidOperationException: attempti

    - by JohnL
    I have a WCF Service Library containing five service contracts. The library is hosted through a Windows Service. Most if not all my configuration for the WCF Library is declaritive. The only thing I am doing in code for configuration is to pass the type of the class implementing the service contracts into ServiceHost. I then call Open on each of the services during the Windows Service OnStart event. Here is the error message I get: Service cannot be started. System.InvalidOperationException: Service '[Fubu.Conversion.Service1' has zero application (non-infrastructure) endpoints. This might be because no configuration file was found for your application, or because no service element matching the service name could be found in the configuration file, or because no endpoints were defined in the service element. at System.ServiceModel.Description.DispatcherBuilder.EnsureThereAreNonMexEndpoints(ServiceDescription description) at System.ServiceModel.Description.DispatcherBuilder.InitializeServiceHost(ServiceDescription description, ServiceHostBase serviceHost) at System.ServiceModel.ServiceHostBase.InitializeRuntime() at System.ServiceModel.ServiceHostBase.OnBeginOpen() at System.ServiceModel.ServiceHostBase.OnOpen(TimeSpan timeout) at System.ServiceModel.Channels.CommunicationObject.Open(TimeSpan timeout) at System.ServiceModel.Channels.CommunicationObject.Open() at Fubu.RemotingHost.RemotingHost.StartServ... protected override void OnStart(string[] args) { // Uncomment to debug this properly //System.Diagnostics.Debugger.Break(); StartService1(); StartService2(); StartService3(); StartService4(); StartService5(); } Each of the above simply do the following: private void StartSecurityService() { host = new ServiceHost(typeof(Service1)); host.Open(); } Service Lib app.congfig summary <services> <service behaviorConfiguration="DefaultServiceBehavior" name="Fubu.Conversion.Service1"> <endpoint address="" binding="netTcpBinding" bindingConfiguration="TCPBindingConfig" name="Service1" bindingName="TCPEndPoint" contract="Fubu.Conversion.IService1"> <identity> <dns value="localhost" /> </identity> </endpoint> <endpoint address="mex" binding="mexTcpBinding" bindingConfiguration="" name="mexSecurity" bindingName="TcpMetaData" contract="IMetadataExchange" /> <host> <baseAddresses> <add baseAddress="net.tcp://localhost:8025/Fubu/Conversion/Service1/" /> </baseAddresses> </host> </service> ... Contract is set up as follows: namespace Fubu.Conversion.Service1 { [ServiceContract(Namespace = "net.tcp://localhost:8025/Fubu")] public interface IService1 { I have looked "high and low" for a solution without any luck. Is the answer obvious? The solution to this does not appear to be. Thanks

  • Choosing between JSON and XML

    - by Midhat
    Previously I used XML soap for data exchange in my web services, But switched to json for another project. Now I cant seem to find a reason to go back to XML, primarily because of the response size difference for large objects. In what case would you need to use XML over json for web service response

  • how to use a tree data structure in C#

    - by matti
    I found an implementation for a tree at this SO question. Unfortunately I don't know how to use it. Also I made a change to it since LinkedList does not have Add method: delegate void TreeVisitor<T>(T nodeData); class NTree<T> { T data; List<NTree<T>> children; public NTree(T data) { this.data = data; children = new List<NTree<T>>(); } public void AddChild(T data) { children.Add(new NTree<T>(data)); } public NTree<T> GetChild(int i) { return children[i]; } public void Traverse(NTree<T> node, TreeVisitor<T> visitor) { visitor(node.data); foreach (NTree<T> kid in node.children) Traverse(kid, visitor); } } I have class named tTable and I want to store it's children and their grandchildren (...) in this tree. My need is to find immediate children and not traverse entire tree. I also might need to find children with some criteria. Let's say tTable has only name and I want to find children with names matching some criteria. tTables constructor gives name a value according to int-value (somehow). How do I use Traverse (write delegate) if I have code like this; int i = 0; Dictionary<string, NTree<tTable>> tableTreeByRootTableName = new Dictionary<string, NTree<tTable>>(); tTable aTable = new tTable(i++); tableTreeByRootTableName[aTable.Name] = new NTree(aTable); tableTreeByRootTableName[aTable.Name].AddChild(new tTable(i++)); tableTreeByRootTableName[aTable.Name].AddChild(new tTable(i++)); tableTreeByRootTableName[aTable.Name].GetChild(1).AddChild(new tTable(i++));

  • Commission Detail Service (REST)

    - by Mike
    Hi, Can someone who uses CJ's Commission Detail Service (REST) tell me what a sample XML response is for this query. None of CJ's Web Services documentation indicates exactly how the XML is formatted and as I don't have any commission payments yet I can only guess the result.

  • Performance of a proposed JEE architecture

    - by kineas
    I have concerns about the performance of the following architecture: j2ee application in an appserver, ejb session bean and DAOs remote (rich) client, a swing app. A classic, form-based client only one stateless ejb, the ejb is accessed via web services, not rmi, through a homegrown framework each web service request will get authenticated against an LDAP no state stored on the server, only client-side sessions I guess working on the rich GUI will involve a remote call in every 2-10 seconds, or more, per user. What do you think?

  • Cannot execute "LOAD DATA LOCAL INFILE" Mysql query in Rails after a connection reconnection

    - by Ngan
    On Rails 2.3.8 (but I think Rails 3 might have this issue as well, not sure): I get an error when trying to execute a LOAD DATA LOCAL INFILE query after reconnecting to a database. I have a process that parses a file that can potentially take a bit of time. During the parsing, Mysql closes the connection due to timeout. This is fine, I do a ActiveRecord::Base.verify_active_connections! and I get the connection back (I do this in several places through my app). However, running a LOAD DATA LOCAL INFILE statement, I get this error: Mysql::Error: The used command is not allowed with this MySQL version It's not a permission issue, I know that for sure. Check out my test in console: ActiveRecord::Base.connection.execute("LOAD DATA LOCAL INFILE '/tmp/test.infile' INTO TABLE users") [Sat Jan 08 00:09:29 2011] (9990) SQL (1.7ms) LOAD DATA LOCAL INFILE '/tmp/test.infile' INTO TABLE users => nil > ActiveRecord::Base.connection.disconnect! => #<Mysql:0x104c6f890> > ActiveRecord::Base.verify_active_connections! [Sat Jan 08 00:09:58 2011] (9990) SQL (0.2ms) SET SQL_AUTO_IS_NULL=0 => {...connection stuff...} > ActiveRecord::Base.connection.execute("LOAD DATA LOCAL INFILE '/tmp/test.infile' INTO TABLE users") [Sat Jan 08 00:10:00 2011] (9990) SQL (0.0ms) Mysql::Error: The used command is not allowed with this MySQL version: LOAD DATA LOCAL INFILE '/tmp/test.infile' INTO TABLE users ActiveRecord::StatementInvalid: Mysql::Error: The used command is not allowed with this MySQL version: LOAD DATA LOCAL INFILE '/tmp/test.infile' INTO TABLE users from ~/gems/activerecord-2.3.8/lib/active_record/connection_adapters/abstract_adapter.rb:221:in `log' from ~/gems/activerecord-2.3.8/lib/active_record/connection_adapters/mysql_adapter.rb:323:in `execute' from (irb):6 I am able to do other queries like SELECT and whatnot, and I will get the correct result. It's just this one that giving me the error. I even tested this with a fresh rails app. You'll notice that I am able to do the exact same query before the disconnect. Thanks for the help!

  • service repository.

    - by SteveCav
    hundreds of our clients around the country have a vb6/MS Access app. The boss needs them to talk to each other, eg client A creates a new task in client B's database, and status updates go back to A. I'm trying to design a WCF system that can accomplish this using a centralized service talking to a service of some kind installed on each client. What I'm wondering is, how the central system knows the address of the clients, ie determine and consume services on the fly? What's a good architecture to fit these requirements?
