  • prgramming a windows service

    - by xarzu
    I have started prgramming a windows service. I have added a notify icon from the toolbox. It has the small notify icon that appears in the systray as a member of those icons. It works so far. So far I have a blank form. I have used the DoubleClick for the notifyIcon to bring up the form (I will use the form for something later). Now I have a list of things I want to accomplish to make this work like a true windows service. First of all, if possible, I owuld like to remove the maximize and cancel button on the form. Most windos service apps that I have seen offer the ability to close the app by right-mouse-button clicking on the notify icon which brings up a menu of options. I see in the properties of the form under Misc there is an CancelButton. But I do not see how do deactivate it. In the Properties of the forum I see under Window Style there is a ControlBox option that, if I turn to false, all three buttons, (minimize, maximize and cancel) go away. These are not what i am looking for. I would not like the option for them to resize, maximize or close the form here. I suspect people will close the box intending to make the box go away while still wanting the app to run. Under the "Focus" caption in Properties, there id "Deactivate". I have created my own event/method/function for this and in debug I noticed that when you click on the x-box in the upper right corner, this function is called. The problem is that after the function is over, the app closes anyway. How do I over-ride this function? Secondly, how do you catch the right button click event on the notify icon in the systray? I can see how to create events for "Click" and "MouseClick" etc. but how so I determine which button was click? Using the right buton click is how such programs know when to pull up a menu. So I would like to know how to do this as well.

  • Posting from JQuery to WCF Service

    - by Villager
    Hello, I have a WCF Service (called "myservice.svc") that takes a message from a user and saves it to the database. It returns a response to the user in the form of a number. This operation looks like this: [OperationContract] [WebGet] public string SubmitMessage(string message) { try { // SAVE TO DATABASE return "1"; } catch (Exception ex) { return "0"; } } I want to call this operation from some JQuery. I'm using the approach shown here: $.getJSON( "/services/myService.svc", {message:"some text"}, function (data) { alert("success"); } ); Oddly, the "success" alert is never displayed. In addition, I have set a breakpoint in my WCF service and it is never being tripped. What am I doing wrong? Thank you

  • Free hosting service for private and public git repositories

    - by Alexander
    Hi, does anyone know a free service for hosting private and public git repositories? There are a lot of services like for example the well known github. Most of them only allow hosting of public repositories. I want to host one or more of my private programming projects using git, but not all of them should be public (at least not for now). I also found the free service GitFarm which is build using the Google App Engine technology, but i couldn't find any information how it works (don't know what "built on Google App Engine technology" means) or if there are any other limitations. Also it seams like there is no web front-end available. An integrated web front-end, bug tracker and stuff like this would also be a big plus!

  • Why is there no music streaming API service?

    - by Chad Johnson
    Apple has decided to kill lala.com. I loved that site. Now, everyone has to go back to paying $0.89+ for songs from Amazon, iTunes, etc. Lame. Rhapsody would be great, except there are no clients for Mac or Linux. They do have a web interface, buy it is nothing compared to lala's web 2.0y interface. What I just don't understand is, why is there no music API streaming service out there? Basically, developers could hook the service into any desktop or web app, and then users of the app could pay $x a month (like with Rhapsody) and play any amount of music, so long as their subscription is active. Why not? Lala streamed music to web browsers, so surely it could be as secure as lala is (was), preventing music theft.

  • Designing Web Service Using Ruby on Rails - Mapping ActiveRecord Models

    - by michaeldelorenzo
    I've put together a RoR application and would now like to publish a RESTful web service for interacting with my application. I'm not sure where to go exactly, I don't want to simply expose my ActiveRecord models since there is some data on each model that isn't needed or shouldn't be exposed via an API like this. I also don't want to create a SOAP solution. My application is built using Rails 2.3.5 and I hope to move to Rails 3.0 soon after its released. I'm basically looking for a way to map my ActiveRecord models to "models" that would be exposed via the web service. Is ActiveResource the correct thing to use? What about ActionWebService?

  • UDDI - find service which name matches exactly name specified in request

    - by empi
    Hi. I'm asking UDDI to find a service with a name specified in request. The code looks like this: UddiConnection uddiConnection = new UddiConnection(uddiAddress); FindService findService = new FindService(); findService.Names.Add(uddiServiceName); ServiceList foundServices = findService.Send(uddiConnection); However, when I ask for SomeService and UDDI has two services SomeService and SomeServiceSecond I get both in found services. How can I ask for service that name exactly matches the name specified? I know I can check the result in my class and limit found services collection but I would like to specify my needs in UDDI inquire. Thanks in advance for help.

  • Allow run-time configuration of web service url using ATL soap and sproxy-generated proxy class

    - by Odrade
    I have a Visual C++ application that communicates with an ASP.NET web service via ATL Soap. The client application uses an sproxy-generated proxy class for the communication. Looking at the generated proxy class, I noticed that the url for the web service is hard-coded in numerous places. It would be preferable for the url to be configurable at run-time (e.g. stored in a config file). Could anyone recommend a method for doing this? It doesn't look like the class generated by sproxy is amenable to hand-editing.

  • Error processing response in .net web service with WSE3 mutualCertificate10Security Assertion

    - by Maeloc
    I am securing a .net web service (framework 2.0) with WSE3 mutualCertificate10Security Assertion. When request are valid all is fine and the response is wellformed, but when the request is invalid (cause a invalid signature, failed check, or soapexception thrown), the web server isn't able to process the response to send to the client. The error in application event log is: An error occured processing an outgoing fault response. Details of the error causing the processing failure: System.InvalidOperationException: Send security filter on the server could not retrieve the operation protection requirements from the operation state. en Microsoft.Web.Services3.Security.SecureConversationServiceSendSecurityFilter.SecureMessage(SoapEnvelope envelope, Security security) en Microsoft.Web.Services3.Security.SendSecurityFilter.ProcessMessage(SoapEnvelope envelope) en Microsoft.Web.Services3.Pipeline.ProcessOutputMessage(SoapEnvelope envelope) en Microsoft.Web.Services3.WseProtocol.GetFilteredResponseEnvelope(SoapEnvelope outputEnvelope) All certificate permissions are OK (when request is OK the web service is able to sign the response). Error occurs only if a soapFault must be returned in the response. Any ideas?

  • Client Web Service call over SSL using Apache Axis

    - by java_pill
    I'm using Apache Axis 1.5.1 to code a web service client connecting to a service over SSL. My application is running in Tomcat with SSL configuration setup in JKS. However, when I connect to the server, the connection is failing because the cert from our client is not being sent to the server. Is this something that has to be set in the client through code? Also note that the server does not need any user name or password authentication. With SSL turned off, everything works fine. Thanks,

  • Service Call very slow if going through HttpHandler

    - by JohnIdol
    I have a WCF client pointing to a WebSphere service. All is good in normal situation except when my calls to the service originate from an HttpHandler - in this case the calls are extremely slow (it takes up to 10 times longer). If I send the exact same envelopes through Soap-UI or without an HttpHandler it's all good. If the envelope is the same the only thing left is the HttpHeader. Would the fact that I am going through an HttpHandler cause changes HttpHeaders compared to normal scenarios? What should I be looking for and is there some config setting that might do the trick? Any help appreciated!

  • Dotnetopenauth oAuth Service provider explanation

    - by ria
    I am a total newbie in the oAuth area and have set up DotNetOpenAuth to set up an oAuth Service provider. The sample provided in the DotNetOpenAuth download is quite confusing for me...maybe cos i am new to this stuff. There is one default page that creates a database and populates the database. Now I browse to the login.aspx and it asks me to put an openid, actually I want to use DNN (which implements DotNetOpenAuth) and i want to use those credentials on another site which will be the oAuth consumer. Can someone explain how to test the oAuth Service provider in the samples of DotNetOpenAuth?

  • The Reason of Service Termination

    - by Mariusz
    I use a service application I created in Delphi. My problem is that it is sometimes terminated by the operating system and I don't know why this happens. When I go the the system events, I can find a piece of information like this one: Event ID: 7034, The [...] service terminated unexpectedly. It has done this [...] time(s). I know you can't give me an answer why this happens, but could you please give me a clue what to pay attention to to find the reason of that behaviour? For instance what kind of exceptions could make the OS close an application. Thank you in advance.

  • Timer in windows service

    - by Markus
    Hi. I have an issue with System.Threading.Timer. I am scheduling some actions using a time in a windows service. The timer starts executing the callback after a specified dueTime period. The windows service starts up after reboot automatically. However, I have observed a strange thing after a system reboot- the callback method starts executing itself 3 or 4 minutes before the specified period. What might be the reason for such behavior? Here is the sample code: TimeSpan timeToWait = this.StartTime - DateTime.Now; Int64 msToSleep = (Int64)Math.Round(timeToWait.TotalMilliseconds); _timer = new Timer(callback_method, null, msToSleep, MinutesScheduledInterval * 60000); where _timer is a member variable, StartTime - the time when the timer should first fire.

  • OCR Web Service

    - by sdfx
    I am searching for an OCR web service (eventually open source, preferably free) that simply receives an image and returns the text of the image in writing. I've looked at tesseract, OCRopus and GOCR but the only open server I could find is WeOCR. Unfortunately the detection rates (at least during my tests) are sub-par and the speed is not much better. Does anyone have any experience with OCR web services? I guess the license of tesseract allows the operation of such a service, are there any out there?

  • List service and services status under Win-7

    - by Ronaldo Junior
    I have a service monitor app that monitors the status of three other servers app - you know those kind of green, red status stuff, start, stop, etc. The problem is that it shows the wrong state in Windows 7 even if the user is the administrator. The start, stop buttons are disabled and the install button enabled, the status color is grey which is also wrong. The start button should be enabled with the service status showing green - the apps are running. If the application is run with the setting "run as administrator" then it behaves normally. The application is written in Delphi 7 and works perfectly in other versions of Windows. This line of code: OpenSCManager(PChar(sMachine),Nil,SC_MANAGER_ALL_ACCESS) always return 0 under Win7, causing the problem. Any ideas and if possible, any workaround apart from "run as administrator". Regards Ronaldo

  • how to deploy wcf-service on iis 6.0

    - by Walter
    I have IIS 6.0 on Windows Server 2003. I installed .Net 3.5 and 4 beta 2. "Normal" asp things are working (perfect). But when I try to navigate to my service (/myServer/MyService.svc) I got a 404. Page not found. To be exact, I got a 404 2 "Web service extension lockdown policy prevents this request." I used ServiceModelReg.exe /ia to make sure that the extension I known and I checked the configuration using: admin-Tools, iis, home-tab, configuration, executable-box, and there: extension: .svc, path: c:\windows\microsoft.net\framework\v4.0.210... verbs: all verbs So everything seems ok. But I still get a 404-2

  • Would a Centralized Blogging Service Work?

    - by viatropos
    If there's a better place to ask this, please let me know. Every time I build a new website/blog/shopping-cart/etc., I keep trying to do the following: Extract out common functionality into reusable code (Rubygems and jQuery plugins mostly) If possible, convert that gem into a small service so I never have to deal with a database for the objects involved (by service, I mean something lean and mean, usually built with the Sinatra Web Framework with a few core models. My assumption is, if I can remove dependencies on local databases, that will make it easier and more scalable in the long run (scalable in terms of reusability and manageability, not necessarily database/performance). I'm not sure if that's a good or bad assumption yet. What do you think? I've made this assumption because of the following reason: Most serious database/model functionality has been built on the internet somewhere. Just to name a few: Social Network API: Facebook Messaging API: Twitter Mailing API: Google Event API: Eventbrite Shopping API: Shopify Comment API: Disqus Form API: Wufoo Image API: Picasa Video API: Youtube ... Each of those things are fairly complicated to build from scratch and to make as optimized, simple, and easy to use as those companies have. So if I build an app that shows pictures (picasa) on an Event page (eventbrite), and you can see who joined the event (facebook events), and send them emails (google apps api), and have them fill out monthly surveys (wufoo), and watch a video when they're done (youtube), all integrated into a custom, easy to use website, and I can do that without ever creating a local database, is that a good thing? I ask because there's two things missing from the puzzle that keep forcing me to create that local database: Post API RESTful/Pretty Url API While there's plenty of Blogging systems and APIs for them, there is no one place where you can just write content and have it part of some massive thing. For every app, I have to use code for creating pretty/restful urls, and that saves posts. But it seems like that should be a service! Question is, is that the main point of a website? Will everyone always need "their own blog"? Why not just have a profile and write lots of content on an established platform like StackOverflow or Facebook?

  • WCF Service Memory Leaks

    - by Mubashar Ahmad
    Dear Devs I have a very small wcf service hosted in a console app. [ServiceContract] public interface IService1 { [OperationContract] void DoService(); } [ServiceBehavior(InstanceContextMode=InstanceContextMode.PerCall)] public class Service1 : IService1 { public void DoService() { } } and its being called as using (ServiceReference1.Service1Client client = new ServiceReference1.Service1Client()) { client.DoService(new DoServiceRequest()); client.Close(); } Please remember that service is published on basicHttpBindings. Problem Now when i performed above client code in a loop of 1000 i found big difference between "All Heap bytes" and "Private Bytes" performance counters (i used .net memory profiler). After investigation i found some of the objects are not properly disposed following are the list of those objects (1000 undisposed instance were found -- equals to the client calls) (namespace for all of them is System.ServiceModel.Channels) HttpOutput.ListenerResponseHttpOutput.ListenerResponseOutputStream BodyWriterMessage BufferedMessage HttpRequestContext.ListenerHttpContext.ListenerContextHttpInput.ListenerContextInputStream HttpRequestContext.ListenerHttpContext Questions Why do we have lot of undisposed objects and how to control them. Please Help

  • A SelfHosted WCF Service over Basic HTTP Binding doesn't support more than 1000 concurrent requests

    - by Krishnan
    I have self hosted a WCF Service over BasicHttpBinding consumed by an ASMX Client. I'm simulating a concurrent user load of 1200 users. The service method takes a string parameter and returns a string. The data exchanged is less than 10KB. The processing time for a request is fixed at 2 seconds by having a Thread.Sleep(2000) statement. Nothing additional. I have removed all the DB Hits / business logic. The same piece of code runs fine for 1000 concurrent users. I get the following error when I bump up the number to 1200 users. System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host at System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags) at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) --- End of inner exception stack trace --- at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.PooledStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.Connection.SyncRead(HttpWebRequest request, Boolean userRetrievedStream, Boolean probeRead) --- End of inner exception stack trace --- at System.Web.Services.Protocols.WebClientProtocol.GetWebResponse(WebRequest request) at System.Web.Services.Protocols.HttpWebClientProtocol.GetWebResponse(WebRequest request) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) at WCF.Throttling.Client.Service.Function2(String param) This exception is often reported on DataContract mismatch and large data exchange. But never when doing a load test. I have browsed enough and have tried most of the options which include, Enabled Trace & Message log on server side. But no errors logged. To overcome Port Exhaustion MaxUserPort is set to 65535, and TcpTimedWaitDelay 30 secs. MaxConcurrent Calls is set to 600, and MaxConcurrentInstances is set to 1200. The Open, Close, Send and Receive Timeouts are set to 10 Minutes. The HTTPWebRequest KeepAlive set to false. I have not been able to nail down the issue for the past two days. Any help would be appreciated. Thank you.
