• Best method to cleanly shut down an application launched via another.

  - by JYelton

  I couldn't find any close answers to this, so I'm consulting the experience of SO users: Scenario: I have two small C# winforms applications where one behaves as a server or host, the other as a client. They share data via SQL Server, in terms of configuration settings. I am currently launching the client application (which only needs to run periodically) from the server application via Process.Start() and terminating it via Process.CloseMainWindow() (after finding it in the process list). While it seems clean enough, I wondered if there's a better way. Question: Which way would be best to instruct the client application to shut down: Continue using Process.CloseMainWindow()? Implement WCF between the applications? (I would need help on how to do this.) Set a variable in SQL that the client application checks for? Some other way?

• Access Rails under /app/, not /app/public/

  - by blinry

  I'm trying to deploy Rails 2.1.2 with Apache 2.2.10 and FastCGI (yeah, bad, ancient, ugly, I know). And I know it's no programming question, but please bear with me. My application can be accessed via example.com/app/public/, but I want to access it via example.com/app/. In my .htaccess-File (in the app/-directory!) I have: RewriteEngine On RewriteBase /app/ RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ public/dispatch.fcgi [QSA,L] How can I forward each request going to app/ to app/public/? Every time I try this (like, with RewriteRule ^.*$ public/$1 [QSA]) I get a routing error: No route matches "/app/" with {:method=>:get} Help?

• ASP.NET MVC, JSON & non JavaScript clients

  - by redsquare

  I need to ensure that an application I am developing is accessable and also works with JavaScript turned off. I just need a pointer to assist with the following. I had 3 'chained' select boxes and I wanted JavaScript enabled clients to have a nice Ajax experience. I can easily write the required functionality to populate the chained boxes on the change event of the preceeding select using jQuery and JSON with a WCF service. However what about the non JavaScript client? Would I wrap a submit next to the select and place these inside their own form to post back with a certain action or different querstring parameter? Can the same controller give me a partial JSON response as well as feeding the full HTML response. Can anyone point me to a good demo that utilises both JSON and normal HTTP posts to produce the same result in ASP.NET MVC. All ASP.NET MVC demo/examples I see forget about the non JavaScript enabled client.

• where is everything in django admin?

  - by FurtiveFelon

  Hi all, I would like to figure out where everything is in django admin. Since i am currently trying to modify the behavior rather heavily right now, so perhaps a reference would be helpful. For example, where is ModelAdmin located, i cannot find it anywhere in C:\Python26\Lib\site-packages\django\contrib\admin. I need that because i would like to look at how it is implemented so that i can override with confidence. I need to do that in part because of this page: http://docs.djangoproject.com/en/dev/ref/contrib/admin/#modeladmin-methods, for example, i would like to override ModelAdmin.add_view, but i can't find the original source for that. As well as i would like to see the url routing file for admin, so i can easily figure out which url corresponding to which template etc. Thanks a lot for any pointers!

• Should we create Virtual Machine environment so a consultant can develop in similiar environment?

  - by ChrisNel52

  This is a large project and currently there are only 3 developers working on it. We have some money in the budget to contract development help from a software consulting firm. However, because the location of our business it would be beneficial if the consultant could do their development off-site. Also, our company policy doesn't allow contract help to VPN into our network, so that is not an option. My question is, would it be a good idea to create a Virtual Machine that copies our internal environment (particularly our database and WCF service) and give the consultant the Virtual Machine image so that they can replicate the environment at their place of work? I haven't worked much with Virtual Machines, so I'm not sure if this is a good idea or if there are huge obstacles that I'm not thinking of. If anyone has ever done anything like this, it would be great to hear the pros/cons. Any help would be appreciated.

• Detect whether certain IIS features are present from InstallScript

  - by Christian Hayter

  I have an InstallScript project written in InstallShield 2010, which, amongst other things, shells out to several .NET MSI installers that install web apps. If any of these web apps are selected for installation by the end user, I need to check for the following optional IIS features from InstallScript code before allowing the install to proceed: ASP.NET (IIS 6+) WCF HTTP Activation (IIS 7+) IIS Metabase and IIS 6 configuration compatibility (IIS 7+) Can anyone point me in the right direction please? Ideally I'm looking for registry values that I can check directly from InstallScript code, but I guess some kind of WMI or COM check would be OK as well. PS: In case it's relevant, we need to support all versions of IIS from 5.1 onwards at this time. If 5.1 support is a problem, we may consider dropping it if we have to.

• Accepting bank account information in a form

  - by jeffthink

  What security concerns are there when accepting a user's bank account information (account number and routing number) via a form on a page that is using SSL, and posting it back to the server where I then curl off a HTTPS request to send that information to an ACH service like First ACH or ACH Direct via their API? We wouldn't be saving the bank account information in our database. I know another option is to use Paypal's Mass Pay API, but they think it's unprofessional (at least for their business) to require customers to have a paypal account to get paid. Thoughts?

• Is there a way in CXF to disable the SoapCompressed header for debugging purposes?

  - by Don Branson

  I'm watching CXF service traffic using DonsProxy, and the CXF client sends an HTTP header "SoapCompressed": HttpHeadSubscriber starting... Sender is CLIENT at 127.0.0.1:2680 Packet ID:0-1 POST /yada/yada HTTP/1.1 Content-Type: text/xml; charset=UTF-8 SoapCompressed: true Accept-Encoding: gzip,gzip;q=1.0, identity; q=0.5, *;q=0 SOAPAction: "" Accept: */* User-Agent: Apache CXF 2.2 Cache-Control: no-cache Pragma: no-cache Host: localhost:9090 Connection: keep-alive Transfer-Encoding: chunked I'd like to turn SoapCompressed off in my dev environment so that I can see the SOAP on the wire. I've searched Google and grepped the CXF source code, but don't see anything in the docs or code that reference this. Any idea how to make the client send "SoapCompressed: off" instead, without routing it through Apache HTTPD or the like? Is there a way to configure it at the CXF client, in other words?

• Cannot resolve view when view is in subdirectory

  - by devzero

  We have a MVC 2.0 / c# 4.0 application that we develop visual studio. We have a part of the site (admin) that we have put in it's own sub directory and with its own routing rules: routes.Add("DomainRoute", new DomainRoute( ConfigurationManager.AppSettings["adminDomain"], // Domain with parameters "{controller}/{action}/{id}", // URL with parameters new { controller = "AdminPage", action = "Admin", id = "", isAdmin = true } We have all the views for the admin site inside an admin sub folder so that you get paths like: \views\admin\auth\login.aspx In the \controllers\admin\authController.aspx file I have a function called login: public ActionResult Login() { return View(); } This works just as it should, ie if i go admin.localhost\auth\login I go to the login page. But if I do a right click in visual studio and "go to view" i get an error "unable to go to matching view". Is there anyway to solve this?

• Determining a location's side of the road position with MapKit

  - by idStar

  Is there a way to use MapKit in iOS7 to not only get geocoding for an address, but determine what side of the road it is on? I'm not trying to build a full function navigation app, but similar to navigation apps that tell you things like "Your destination is in 100 feet on the right", I'd like to be able to obtain this information. Does MapKit give one a way to do this? Do I need to adopt routing privileges to access such, or is this just not available in the SDK period? If not available in the iOS7 SDK, knowing what options exist as services, would be a helpful pointer.

• My C# program running as Windows Service is blocking Windows XP from hibernation

  - by sherpa

  I have Windows Service written in C#. It starts two threads, one is pooling a Web Service, second is waiting on a Monitor object for a new job to arrive. Besides that, the main thread acts as a WCF service host using NetNamedPipeBinding. It lets the client application to register a callback and then sends notifications back. The problem I have is that when this Windows Service is running, I cannot hibernate or Standby my computer which is running on Windows XP, SP3. When I set Windows to hibernate or standby, nothing happens. Then, at the moment when I go to Service Manager and stop the service, the system hibernation starts immediately. The service class extending the ServiceBase has properties like CanHandlePowerEvent, CanPauseAndContinue, etc. set to true... That didn't make any difference. The question is: what can be blocking the Hibernation/Standby from proceeding? What should I take care about to avoid it?

• Proxy object references in MVC code

  - by krystan honour

  Hi there, I am just figuring out best practice with MVC now I have a project where we have chosen to use it in anger. My question is. If creating a list view which is bound to an IEnumerable is this bad practise? Would it be better to seperate the code generated by the WCF Service reference into a datastructure which essentially holds the same data but abstracts further from the service, meaning that the UI is totally unaware of the service implementation beneath. or do people just bind to the proxy object types and have done with it ? My personal feeling is to create an abstraction but this seems to violate the DRY principle.

• Best Technologies for AJAX Web Development

  - by floatingfrisbee

  Hey Everyone, I have some experience in AJAX development, mostly on .NET and MooTools. However, I want to learn more and see what others out there thought about the various other options available. I am looking more for advise about the front end. The back end, I will most probably be coding up in .NET using c# and WCF services. Please feel free to provide me as much information as you can. Also I would appreciate any links to resources. List of Options (feel free to add) Write my own Javascript Use a frame work like MooTools, JQuery etc. Which one is better? Use Google Web Toolkit. Am I tying myself to limitations of GWT? Or are there not limitations? ASP.NET AJAX WPF (Will this run on non IE browsers?) Flash (it'll be a pain to learn action script) Thanks Jaspreet

• MVC 2 Beta DefaultControllerFactory with Areas

  - by stoto

  Why default factory WON'T return full name of the controllers (with namespaces)? I'm using Service Locator and autofac. using System.Web.Mvc; using Microsoft.Practices.ServiceLocation; namespace Application.Core.MVC { public override IController CreateController(System.Web.Routing.RequestContext requestContext, string **controllerName**) { return ServiceLocator.Current.GetInstance<IController>(controllerName); } } I had two home controllers (one under area Blog) http://localhost/Home http://localhost/Blog/Home controllerName return only "Home" without full qualified name for both in above code. This creates a problem when I try to regiser controllers' names for dependency injection. Here is how I register controllers right now according to this situation. Even this brings up the pages without exception. But When I access http://localhost/Home, both controllers invoked regardlessly. foreach (var tp in currentAssemblyControllersTypes) builder.Register(tp).FactoryScoped().Named(tp.Name.Replace("Controller", "")); Anyone can help?Thanks.

• Calling a web service from a windows service

  - by Arun

  I'm sure there's an elegant solution to the problem but I just can't get my head around it. I am trying to call a web service from within a Windows service. The web service is secured (using Windows authentication). The account that the windows service runs under does have the rights to call the web service but I can't figure out how to get those credentials and send them off to the web service. The web service is WCF and is hosted on the same machine (in IIS) as the windows service.

• .NET Deployment of Interface/Classes for Command Pattern Question

  - by Jonno

  In theory I would like to produce 2 projects: 1) Asp.net (Sever A) 2) DAL running (Server B) I would like to utilise command objects to comunicate with the DAL. ASP.net instantiates a command class e.g. CmdGetAllUsers which impliments IMyCommand interface and sends it to the DAL (using ASMX or WCF). My question is: Would the class definition of CmdGetAllUsers need to exist on the DAL server? Or would having the interface definition be enough? My goal is to reduce the need to redeploy the DAL code, and have it as a fairly simple pass-through layer. Many thanks for your time.

  Hi I get the following data back from my WCF Data Service (I cut out the metadata) { "d" : [ {"CodeId": 6, "Title": "A Child Sub Item", "Parent":}, {"CodeId": 5, "Title": "Another Root Item", "Parent": -1}, {"CodeId": 4, "Title": "Child Item", "Parent": 2}, {"CodeId": 2, "Title": "Root Item", "Parent": -1} ] } I am trying to get this into a <ul> style tree with Parent = -1 as root and then the rest as sub items of their parent id's. Can anyone help me please, preferably in jQuery? I will use this in jstree if someone knows of a better way to do this. Thanks

• How to integrate access control with my ORM in a .net windows form application?

  - by Ying

  I am developing a general database query tools, a .Net 3.5 Windows Form application. In order to make the presentation layer is independent of the database layer. I use an ORM framework, XPO from DevExpress. But, I have no access control function built in. I surfed Internet and I found in WCF Data Services, there is an interesting concept, Interceptor, which is following AOP(Aspect Oriented Programming). I am wondering who has such an experience to build access control in ORM. My basic requirement is : It should be a general method and controlled by users in runtime. So any hard coding is not acceptable. It could be based on attribute, database table, or even an external assembly. I am willing to buy a ready solution. According to the idea of AOP, an access control function can be integrated with existing functions easily and nearly not knowingly to the previous developer;) Any suggestions are welcome.

• .NET WebService IPC - Should it be done to minimise some expensive operations?

  - by Kyle

  I'm looking at a few different approaches to a problem: Client requests work, some stuff gets done, and a result (ok/error) is returned. A .NET web service definitely seems like the way to go, my only issue is that the "stuff" will involve building up and tearing down a session for each request. Does abstracting the "stuff" out to an app (which would keep a single session active, and process the request from the web service) seem like the right way to go? (and if so, what communication method) The work time is negligible, my concern is the hammering the transaction servers in question will probably get if I create/drop a session for each job. Is some form of IPC or socket based communication a feasible solution here? Thoughts/comments/experiences much appreciated. Edit: After a bit more research, it seems like hosting a WCF service in a Windows Service is probably a better way to go...

• Dependency Injection -Colloquial explanation

  - by nettguy

  Recently I was asked to express the DI in colloquial explanation. I answered : 1) I am going to a hotel.I ordered food.The hotel management asks me to clean the plates and clean the tables.So here i am a client,I am responsible for managing the service (Instantiating,executing,disposing).But DI decouples such tasks so the service consumer no need not worry about controlling the life cycle of the service. 2) He also asked is there any microsoft API follows DI ?.I answered (This was my guess) In WCF you can create a Proxy using ChannelFactory that controls the life time of your factory. for item (1) he said only 10% is correct for item(2) he said that is factory pattern not dependency injection. Actually what went wrong in my explanation (apart from my bad English) ? What is the real answers for those? I am waiting for your valuable suggestions.

• Why can't I expose an interface in a .NET asmx web service?

  - by mcliedtk

  I have a .NET web service (using asmx...have not upgraded to WCF yet) that exposes the following: public class WidgetVersion1 : IWidget {} public class WidgetVersion2 : IWidget {} When I attempt to bind to the web service, I get the following serialization error: Cannot serialize member WidgetVersion1 of type IWidget because it is an interface. I have tried adding various attributes to the IWidget interface (XmlIgnore, SoapIgnore, NonSerialized), but they are not valid on an interface. Does anyone know why I am unable to expose the interface? I assume WSDL does not support interfaces, but couldn't .NET get around this by simply not serializing the interface? Are there any ways around this apart from removing the IWidget interface from the WidgetVersion1 and WidgetVersion2 class definitions?

• Why do I get HTTP Code 414 on one network but not another?

  - by Stephen Darlington

  I have an otherwise working iPhone program. A recent change means that it generates some very long URLs (over 4000 characters sometimes) which I know isn't a great idea and I know how to fix -- that's not what I'm asking here. The curious thing is that when I make the connection using a 3G network (Vodafone UK) I get this HTTP "414 Request-URI Too Long" error but when I connect using my local WiFi connection it works just fine. Why would I get different results using different types of network? Could they be routing requests to different servers depending on where the connection originates? Or is there something else at stake here? The corollary questions relate to how common this is. Is it likely to happen whenever I use a cell network or just some networks?
