• Enclosing service execution in try-catch

  - by Sorin Comanescu

  Hi, Below is the usual Program.cs content for a windows service program: static class Program { /// <summary> /// The main entry point for the application. /// </summary> static void Main() { ServiceBase[] ServicesToRun; ServicesToRun = new ServiceBase[] { new MyService() }; ServiceBase.Run(ServicesToRun); } } Is it a bad practice to enclose the ServiceBase.Run(...) in a try-catch block? Thanks.

• What data/service is where?

  - by MrTelly

  What management tools (open source or otherwise) are there to track the location of data, the services that deliver/use that data and the services themselves. If you believe the snake oil a combination of DB, ESB and SOA will deliver anything anywhere, but how do you know what's where. BTW I'm not interested at the WSDL level, I'm thinking of a tool that the users/BA community would populate and use. A combination of SOA and Database is now the bedrock of most applications, however what used to be called Data Dictionaries, and would now be Service Catalogues? or MetaData repositories still seem to live in purely DataCentric world.

• Creating a simple wcf service publishing it to my webhotel, and get it to work

  - by H4mm3rHead

  Hi, This seems to be a recurring problem to me. I want to get started doing wcf services. I create a new Wcf Service Library, compile it, and publish it using FTP to my providers webhotel. But its not working. I somehow cant get access. I dont want some fancy security model - i just want to get a hole through to my simple webservice. Seems that its the part when i publish it to my webhotel (in a subdomain) that breaks the webservice - its working perfectly when starting it locally. How to proceed anyone?

• Service for converting SWFs with ActionScript to Video (MPEG, AVI, or MOV)

  - by pcooley

  The SWF files generated by our application are a basic template that reference external resources (images, and textual data) that actionscript uses to fuel the display. Thus the SWF is responsible for the creative layout of the screen the flash player. It is the results of this actions script, images, and textual data that need to be converted to a video format. Is anyone familiar with an online service that would be able to convert such .swf files that our site generates to a video format (say .avi, .mpeg, .mov). Or an application? Note: A more common case might be the conversion of an embedded FLV to a video, but this is not our need

• Tridion Core Service - Transaction roll back isnt working

  - by Tamir Lahav

  We are using the core service in ASP.NET custom page in order to create pages and components and sevenral updates (checkout,save and chekin). we want those operations to work in transaction, we tried to implement it acording to some examples over the net. However we didn't succeded operating the rollback. It seems that the operation are immediately performed without waiting for the comit . The code we used for simple check out - roll back operation for example is TransactionOptions txOptions = new TransactionOptions { IsolationLevel = IsolationLevel.ReadCommitted }; using (TransactionScope scope = new TransactionScope( TransactionScopeOption.Required, txOptions)) { using (CoreService2010Client m_client = new CoreService2010Client()) { PageData pp = m_client.CheckOut("tcm:309-36311-64", false, new ReadOptions()) as PageData; } scope.Dispose(); } We also added this recomended configuration to the web config bindings section What are we missing ?

• .NET Web Service Proxy is adding special characters in XML

  - by xkingpin

  My web service proxy seems to be adding special characters like "*" and "#" etc. within the xml nodes. My proxy created lists using arrays of objects. I am trying to create a generic list and then doing list.ToArray() to set the proxy MyProxyObject[] object. Is this the cause of the problem I am having? I plan on running fiddler on the request later but it is over SSL and I do not have access to the URL at the moment. Here is an example of the XML that is generated: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> * <soap:Body> o I'm a little concerned because the special characters are even occuring before the array nodes

• Service-Based Authentication Using Tokens

  - by jerhinesmith

  I'm having a tough time trying to find clear and concise examples of how one would implement a service-based authentication scheme using tokens. As far as I can tell, the basic steps are as follows: Client requests username/password from user Client passes username/password to identity provider Provider checks username/password and sends back a token if the user is valid Client does something with the token? The third and fourth step are where I'm getting stuck. I assume the "token" in this case just has to be either an encrypted string that the client can decrypt or some random string that gets stored somewhere (i.e. a database) that the client can then verify against, but I'm not really sure what the client is then supposed to do with the token or why you even need a token at all -- couldn't a simple user ID also suffice?

• 2 way communication over http between a .Net service and Windows Forms Client

  - by user1802969

  I am looking to accomplish 2 way communication over http between a .Net service (WCF SOAP or REST, both options are open) hosted on IIS 7 and Windows Forms Client running on Windows 7. WebSockets are not supported with IIS 7 and all other Comet techniques allow only the web server to push data to client and not the other way around. The client will be very chatty, and there are thousands of clients, so I want to avoid creating a new HTTP request for each message to the server, though that is the last option. Is there any way to do this ?

• How to programmatically generate WSDL from WCF service (Integration Testing)

  - by David Christiansen

  Hi All, I am looking to write some integration tests to compare the WSDL generated by WCF services against previous (and published) versions. This is to ensure the service contracts don't differ from time of release. I would like my tests to be self contained and not rely on any external resources such as hosting on IIS. I am thinking that I could recreate my IIS hosting environment within the test with something like... using (ServiceHost host = new ServiceHost(typeof(NSTest.HelloNS), new Uri("http://localhost:8000/Omega"))) { host.AddServiceEndpoint(typeof(NSTest.IMy_NS), new BasicHttpBinding(), "Primary"); ServiceMetadataBehavior behavior = new ServiceMetadataBehavior(); behavior.HttpGetEnabled = true; host.Description.Behaviors.Add(behavior); host.AddServiceEndpoint(typeof(IMetadataExchange), MetadataExchangeBindings.CreateMexHttpBinding(), "mex"); host.Open(); } Does anyone else have any better ideas?

• Err Web Service?

  - by j-t-s

  Hi All I am trying to implement a feature. But I've never had anything to do with "Web Services" before, other than using them. I have a desktop application, and I want that application to be able to sort of "post" some information (i.e. email address, username, user-selected options (just plain text) etc) to an application or "web service" on my ASP.NET web server. Can somebody please guide me in the right direction? How would I accomplish this? Thank you :) Jason

• C# Windows Service Intermittent Method Call

  - by Goober

  Scenario I have a C# Windows Service that essentially subscribes to some events and if anything is triggered by the events, it carries out a few tasks. The Thing... ....is that these events are monitoring processes, which I need to restart at certain times of the day. Question What's the best way I can go about performing this task at an exact time? Thoughts so far are: 1)To use a timer that checks what time it is every few minutes. 2)Something that isn't a timer and doesn't suck as an implementation. Help greatly appreciated.

• Set existing Web Service Extension to "Allow" using WiX

  - by Friend Of George

  In IIS Manager under Web Service Extensions, ASP.NET v2.0.50727 is set to "Prohibited" by default. I would like to set this to Allow during the install. I am currently using WiX Version 2. I have tried using: <Component Id="Allow_WebServiceExtension_ASP.NET_2.0" DiskId="1" Guid="02247363-E423-41E1-AC15-BEF589B65A4D"> <WebServiceExtension Id="WebServiceExtension_ASP.NET_2.0" Allow="yes" File="%SystemRoot%\Microsoft.NET\Framework\[DOTNETFRAMEWORKVER]\aspnet_isapi.dll" Description="ASP.NET v2.0.50727" UIDeletable="no" /> </Component> This adds a second ASP.NET 2.0.50727 entry and does not enable the first.

• Async data loading with WCF service with UI capabilities

  - by Jojo

  I'm working on complex user control(with Telerik components). I'm trying to implement following functionality: Typing some text in RadTextBox(let say: "Hello.txt"). Clicking on Button "Check". onClientClick for button "Check" will call WCF method with parameters. Let say that this request/response will take more that 10 seconds, meanwhile I'll see loading image near TextBox AND the most important, I can continue to work on other fields. When WCF service responses UI will be updated with the result. Thanks in advance

• Custom changeable handler when a Service finishes downloading a file

  - by jax

  I have a Service that downloads a file from the internet. What I want is for the response (an InputStream in this case) to be handled by a custom handler that can be switched (like a strategy pattern) but I can't figure out how to do this. So basically the User of the API would be able to plug in different handlers for the response, some would parse XML, others might save files etc. I realise I could pass through the activity context and execute the method from this (given some interface) but I don't want to do this obviously, in case the Activity is closed in the meantime while the file is still downloaded. How might I do this?

• I changed the web service declaration and then wsimport says that I have a repeated message

  - by Oso

  I had a Web service method working fine on Tomcat as deployed by Netbeans 6.8. Then I had to add a new parameter for the same method so I erased the method and then added a new one with the same name but different parameters. After that, ws-import keeps on telling me that I have duplicated messages for such method, and if I remove the new one, the WSDL will still show me the old one with the old parameter list. How do I get rid of the old one? thanks in advance.

• Free service that allows storing game data online?

  - by StackedCrooked

  I have created a small game in Java and I would like to add the ability for a player to publish his highscores online. I'm willing to write the server software myself (it's easy these days with Ruby Mongrel, or even C++). All I just need to have some sort hosting. One solution that immediately comes to mind is Amazon EC2. But that's kind of expensive for my needs. Since the requirements are very minimal (I don't even need a website, just a web service) I think there may be a cheaper solution out there. Does anyone know of a free or cheap provider for this kind of thing?
