  • Application threads vs Service threads

    - by zerayaqob
    What are the advantages/disadvantages in placing a lengthy network access code in a thread in an activity or a thread in a service? How would it affect the application? I am writing a streaming audio player and from what I've read so far putting the code in a service will still end up blocking the application so a new thread is needed, does anyone know if it makes more sense to put this piece of code in a service. Thanks

  • How to Deserialize XMLDocument to object in C#?

    - by Deepfreezed
    I have a .Net webserivce that accepts XML in string format. XML String sent into the webserivce can represent any Object in the system. I need to check the first node to figure out what object to deserialize the XML string. For this I will have to load the XML into an XMLDocument (Don't want to use RegEx or string compare). I am wondering if there is a way to Deserialize the XMLDocument/XMLNode rather that deserializing the string to save some performance? Is there going to be any performance benefit serializing the XMLNode rather that the string? Method to Load XMLDocument public void LoadFromString(String s) { m_XmlDoc = new XmlDocument(); m_XmlDoc.LoadXml(s); } Thanks

  • How to unit test C# Web Service with Visual Studio 2008

    - by Steven Behnke
    How are you supposed to unit test a web service in C# with Visual Studio 2008? When I generate a unit test it adds an actual reference to the web service class instead of a web reference. It sets the attributes specified in: http://msdn.microsoft.com/en-us/library/ms243399(VS.80).aspx#TestingWebServiceLocally Yet, it will complete without executing the test. I attempted to add the call to WebServiceHelper.TryUrlRedirection(...) but the call does not like the target since it inherits from WebService not WebClientProtocol. Thanks, Steven

  • Preserving Language across inline Calculated Members in SSAS

    - by Tullo
    Problem: I need to retrieve the language of a given cell from the cube. The cell is defined by code-generated MDX, which can have an arbitrary level of indirection as far as calculated members and sets go (defined in the WITH clause). SSAS appears to ignore the Language of the specified members when you declare a calculated member inline in the query. Example: The cube's default locale is 1033 (en-US) The cube contains a Calculated Measure called [Net Pounds] which is defined as [Net Amt], language=2057 (en-GB) The query requests this measure alongside an inline calculated measure which is simply an alias to the [Net Pounds] When used directly, the measure is formatted in the en-GB locale, but when aliased, the measure falls back to using the cube default of en-US. Here's what the query looks like: WITH MEMBER [Measures].[Pounds Indirect] AS [Measures].[Net Pounds] SELECT { [Measures].[Pounds Indirect], [Measures].[Net Pounds] } ON AXIS (0) FROM [Cube] CELL PROPERTIES language, value, formatted_value The query returns the expected two cells, but only uses the [Net Pounds] locale when used directly. Is there an option or switch somewhere in SSAS that will allow locale information to be visible in calculated members? I realise that it is possible to declare the inline calculated member in a particular locale, but this would involve extracting the locale from the tuple first, which (since the cube's member is isolated in the application's query schema) is unknown.

  • Problem with openssl_get_privatekey returning false

    - by Joe Corkery
    I am trying to generate a signed url for Amazon's CloudFront service but am running into problems in that the openssl_get_privatekey function appears to be returning false and I can't quite figure out why. Here is the code (PHP) that I am using: $priv_key = file_get_contents(path_to_my_pem_file); $priv_keyid = openssl_get_privatekey($privkey); Unfortunately, everytime I try this openssl_get_privatekey fails silently and I run into errors when I try to sign with openssl_sign later on. I've tried printing out the contents of $priv_key after it has been read in and it appears to be correct. I'm running this on RHEL 5.4 using PHP 5.2.13. I've confirmed that file pem file is readable and I've also run dos2unix on it just in case (didn't work before or after). Any thoughts would be greatly appreciated as I am relatively new to both PHP and openssl.

  • free web service returning city names, city codes and time zone

    - by EugeneP
    Do you know a web service that's able let's say get a full list of cities in the world with names, short names like PAR for Paris and time zones? Or at least query by city name: Paris - timezone=+02:00, abbrev=PAR Also, what I see here: http://www.earthtools.org/webservices.htm#timezone offset The number of hours offset from UTC disregarding any correction for daylight saving time. That's not a desired result. Of course we need this correction!

  • How to return a complex object from an axis web service

    - by jani
    Hi all, I am writing a simple web service to return an object with 2 properties. I am embedding the service into an existing web application. My wsdd looks like this. <globalConfiguration> <parameter name="adminPassword" value="admin"/> <parameter name="sendXsiTypes" value="true"/> <parameter name="sendMultiRefs" value="true"/> <parameter name="sendXMLDeclaration" value="true"/> <parameter name="axis.sendMinimizedElements" value="true"/> <requestFlow> <handler type="java:org.apache.axis.handlers.JWSHandler"> <parameter name="scope" value="session"/> </handler> <handler type="java:org.apache.axis.handlers.JWSHandler"> <parameter name="scope" value="request"/> <parameter name="extension" value=".jwr"/> </handler> </requestFlow> </globalConfiguration> <handler name="LocalResponder" type="java:org.apache.axis.transport.local.LocalResponder"/> <handler name="URLMapper" type="java:org.apache.axis.handlers.http.URLMapper"/> <handler name="Authenticate" type="java:org.apache.axis.handlers.SimpleAuthenticationHandler"/> <transport name="http"> <requestFlow> <handler type="URLMapper"/> <handler type="java:org.apache.axis.handlers.http.HTTPAuthHandler"/> </requestFlow> </transport> <transport name="local"> <responseFlow> <handler type="LocalResponder"/> </responseFlow> </transport> <service name="helloService" provider="java:RPC" style="document" use="literal"> <parameter name="className" value="ws.example.HelloService"/> <parameter name="allowedMethods" value="*"/> <parameter name="scope" value="application"/> </service> I am able to deploy it successfully.

  • RDLC - Adding a Data Source in VS2010

    - by Kezzer
    Greetings. I have an RDLC file and am wanting to add a data source to it, although without any luck so far. The data source is a custom class written by myself (just to add, we do this all the time). We recently converted over to the VS2010 RDLC format which caused some problems, but we've made some changes to our implementation that workaround the more major issues. So, back to the issue at hand, when I attempt to add my data source to the DummyDataSource list in the RDLC view in VS2010 it just does nothing, however it does add the data source to the list of data sources, but you can't select it from the drop-down list in the RDLC view which means I can't add the data source at all. Has anyone come across this problem? Is there anything I need to check? I've searched with fervour and had no luck.

  • C# Process Exited event not firing from within webservice

    - by davidpizon
    I am attempting to wrap a 3rd party command line application within a web service. If I run the following code from within a console application: Process process= new System.Diagnostics.Process(); process.StartInfo.FileName = "some_executable.exe"; // Do not spawn a window for this process process.StartInfo.CreateNoWindow = true; process.StartInfo.ErrorDialog = false; // Redirect input, output, and error streams process.StartInfo.UseShellExecute = false; process.StartInfo.RedirectStandardOutput = true; process.StartInfo.RedirectStandardError = true; process.StartInfo.RedirectStandardInput = true; process.EnableRaisingEvents = true; process.ErrorDataReceived += (sendingProcess, eventArgs) => { // Make note of the error message if (!String.IsNullOrEmpty(eventArgs.Data)) if (this.WarningMessageEvent != null) this.WarningMessageEvent(this, new MessageEventArgs(eventArgs.Data)); }; process.OutputDataReceived += (sendingProcess, eventArgs) => { // Make note of the message if (!String.IsNullOrEmpty(eventArgs.Data)) if (this.DebugMessageEvent != null) this.DebugMessageEvent(this, new MessageEventArgs(eventArgs.Data)); }; process.Exited += (object sender, EventArgs e) => { // Make note of the exit event if (this.DebugMessageEvent != null) this.DebugMessageEvent(this, new MessageEventArgs("The command exited")); }; process.Start(); process.StandardInput.Close(); process.BeginOutputReadLine(); process.BeginErrorReadLine(); process.WaitForExit(); int exitCode = process.ExitCode; process.Close(); process.Dispose(); if (this.DebugMessageEvent != null) this.DebugMessageEvent(this, new MessageEventArgs("The command exited with code: " + exitCode)); All events, including the "process.Exited" event fires as expected. However, when this code is invoked from within a web service method, all events EXCEPT the "process.Exited" event fire. The execution appears to hang at the line: process.WaitForExit(); Would anyone be able to shed some light as to what I might be missing?

  • Where is the displaytag of scheduled reporting?

    - by Nathan Feger
    So I have been making some reports and using displaytag to output these reports in html, csv, excel, pdf, etc. They are paginated, and take a simple object graph... and output excellent results everytime, with very little code. However, I need to use displaytag or its equivalent outside of a jsp. So that a user can schedule a report to run, and that report is stored in a db, or emailed for later viewing. I have looked at jasper-based reporting solutions, but making a jasper jrxml file is just a nightmare. I know there are gui tools to help, but I'm content with the simple output of displaytable, so I'm happy to give up that control for ease of implementation. Really, if I could take the display:table config out of the jsp I would, so please keep that in mind when proposing a solution. btw, java solutions would be my cup of tea.

  • Android using ksoap calling PHP SOAP webservice fails: 'procedure 'CheckLogin' not found

    - by AmazingDreams
    I'm trying to call a PHP SOAP webservice. I know my webservice functions correctly because I use it in a WPF project succesfully. I'm also building an app in android, using the same webservice. The WSDL file can be found here: http://www.wegotcha.nl/servicehandler/service.wsdl This is my code in the android app: String SOAP_ACTION = "http://www.wegotcha.nl/servicehandler/CheckLogin"; String NAMESPACE = "http://www.wegotcha.nl/servicehandler"; String METHOD_NAME = "CheckLogin"; String URL = "http://www.wegotcha.nl/servicehandler/servicehandler.php"; String resultData = ""; SoapSerializationEnvelope soapEnv = new SoapSerializationEnvelope(SoapEnvelope.VER11); SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); SoapObject UserCredentials = new SoapObject("Types", "UserCredentials6"); UserCredentials.addProperty("mail", params[0]); UserCredentials.addProperty("password", md5(params[1])); request.addSoapObject(UserCredentials); soapEnv.setOutputSoapObject(request); HttpTransportSE http = new HttpTransportSE(URL); http.setXmlVersionTag("<?xml version=\"1.0\" encoding=\"utf-8\"?>"); http.debug = true; try { http.call(SOAP_ACTION, soapEnv); } catch (IOException e) { e.printStackTrace(); } catch (XmlPullParserException e) { e.printStackTrace(); } SoapObject results = null; results = (SoapObject)soapEnv.bodyOut; if(results != null) resultData = results.getProperty(0).toString(); return resultData; Using fiddler I got the following: Android request: <?xml version="1.0" encoding="utf-8"?> <v:Envelope xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns:d="http://www.w3.org/2001/XMLSchema" xmlns:c="http://schemas.xmlsoap.org/soap/encoding/" xmlns:v="http://schemas.xmlsoap.org/soap/envelope/"><v:Header /> <v:Body> <n0:CheckLogin id="o0" c:root="1" xmlns:n0="http://www.wegotcha.nl/servicehandler"> <n1:UserCredentials6 i:type="n1:UserCredentials6" xmlns:n1="Types"> <mail i:type="d:string">myemail</mail> <password i:type="d:string">myhashedpass</password> </n1:UserCredentials6> </n0:CheckLogin> </v:Body> </v:Envelope> Getting the following response: Procedure 'CheckLogin' not present My request produced by my WPF app looks completely different: <s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"> <s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <UserCredentials6 xmlns="Types"> <mail>mymail</mail> <password>mypassword</password> </UserCredentials6> </s:Body> </s:Envelope> After googling my ass off I was not able to solve this problem by myself. It may be possible there are some weird things in my Java code because I changed a lot since. I hope you guys will be able to help me, thanks. EDIT: My webservice is of document/literal encoding style, after doing some research I found I should be able to use SoepEnvelope Instead of SoapSerializationEnvelope Though when I replace this I get an error before the try cache block, causing my app to crash. Error: 11-04 16:23:26.786: E/AndroidRuntime(26447): Caused by: java.lang.ClassCastException: org.ksoap2.serialization.SoapObject cannot be cast to org.kxml2.kdom.Node Which is caused by these lines: request.addSoapObject(UserCredentials); soapEnv.setOutputSoapObject(request); This may be a solution though, how do I go about this? I found nothing about using a SoapEnvelope instead of a SoapSerializationEnvelope except for this awesome tutorial: http://ksoap.objectweb.org/project/mailingLists/ksoap/msg00849.html

  • C# WMI, Performance Counters, & SNMP Oh My!

    - by Keith
    I have a C# windows service which listens to a MSMQ and sends each message out as an email. Since there's no UI, I'd like to offer an ability to monitor this service to see things such as # messages in queue, # emails sent (by message type perhaps), # of errors, etc. What is the best/recommended way to accomplish this? Is it WMI or performance counters? Is this data viewed using PerfMon or WMI CIM Studio? Does any approach allow one to monitor the service real-time as well as providing historical analysis? I can dig into the details myself but would appreciate some broad guidance to help demystify this subject.

  • Max TCP Connections to a machine

    - by A9S6
    I am creating a Windows Service in .NET to which N number of client can connect. The service starts a TCP listener and accepts the client connections. The problem I am facing is that I can only open 10 connections to this service. The listener::AcceptTcpClient() method accepts only 10 connection and throws an exception for 11th one. The client application uses the System.Net.Sockets.TcpClient class and the service is using System.Net.Sockets.TcpListener class. This is the exception that I am getting when I try to make a number of connections in a for loop to this service (after the 10th connection is made): "Unable to read data from Transport connection: An exsting connection was forcibly closed by remote host"

  • Visual Studio 2010: adding a service reference to a 2008 generated wsdl

    - by Snake
    Doesn't produce a app.config . In my team there is a guy who has Visual Studio 2008, he created a webservice. Then there is me, adding this webservice to a console project. Adding the service reference goes without problems but no valid app.config is generated. It's just empty <configuration> </configuration> When I disable 'reuse types' in my service reference it works but then I get an ambiguous error. Is this a bug? I found http://stackoverflow.com/questions/2159107/visual-studio-does-not-generate-app-config-content-when-add-service-reference this one, but there is no solution there, so I thought I bump the problem up again. Thanks
