  • Self host WCF (Windows Communication Foundation) Ajax services

    - by Wayne Lo
    I am having trouble to understand how to expose the WCF services through Javascript. Here are what I found after days of research: Exposing WCF services through Javascript but not self host: http://msdn.microsoft.com/en-us/library/bb472488.aspx In this example, it requires the creation of a .svc file <%@ServiceHost language="c#" Debug="true" Service="Microsoft.Samples.XmlAjaxService.CalculatorService" Factory="System.ServiceModel.Activation.WebServiceHostFactory" %> Self host WCF Ajax services but not exposing the services through Javascript. http://msdn.microsoft.com/en-us/library/bb943471%28v=VS.100%29.aspx Please help.

  • force users to activate account before using service?

    - by fxuser
    i am not sure if this is the correct SE site to post this, but ill go on... So at the moment i force my users to activate their account upon registration if they want to sign in. I see some decent sites let their users sign in and use their features even their account is not activated and just show a message on top of the page letting them know that their account is not yet activated and that you need to activate it. So which practice is best? Should i stick with that i have or change it?

  • Tip: Regularily reset SharePoint Timer Service during development

    - by panjkov
    There is an interesting issue that can occur on development machines during development of SharePoint solutions that contain Site Templates or list templates in certain scenarios when site creation is not done manually, but using some kind of Custom Timer Job. The issue manifests in a way that even after retraction of old WSP and deployment of new WSP, even after performing IISRESET, sites created with new WSP don't have applied latest changes which are part of new WSP, but instead use (contain)...(read more)

  • ISA Web Farm and WCF service hosted in a Windows Service with basicHttpBinding

    - by Ryan Pedersen
    I have created a WCF service that needs to be hosted in a Window Service because it is participating in a P2P mesh (NetPeerTcpBinding). When I tried to host the WCF Service with NetPeerTcpBinding endpoints in the IIS Service container the service wouldn't run because it turns out that the P2P binding doesn't work in IIS. I have exposed a HTTP endpoint from the WCF service hosted in a Windows Service container and I want to know if there is a way to create an ISA Web Farm that will route traffic to http endpoints on two machines each running the same WCF service in a Windows Service container.

    - by ProfessionalAmateur
    Trying to install a fresh install of Sharepoint 2010 (w/ SP1) and SQL Server 2012 PowerPivot for Sharepoint. The prerequisites clearly show that Sharepoint 2010 SP1 is needed, which we have installed. However after when trying to install the SQL Server portion we consistently fail the rule SharePoint version requirement for PowerPivot for SharePoint' validation in theSQL Server` install process. Here is the process we are following: 1. install Sharepoint 2010 2. install Sharepoint 2010 SP1 3. install SQL Server 2012 PowerPivot for SharePoint Here is a screen shot of the error and the log file error. We are completely stuck at this point, anyone run into this before?

  • Android - binding to service

    - by tommy
    Hi: I can't seem to get an activity to bind to a service in the same package. The activity looks like this: public class myApp extends TabActivity { static private String TAG = "myApp"; private myService mService = null; private ServiceConnection mServiceConn = new ServiceConnection(){ public void onServiceConnected(ComponentName name, IBinder service) { Log.v(TAG, "Service: " + name + " connected"); mService = ((myService.myBinder)service).getService(); } public void onServiceDisconnected(ComponentName name) { Log.v(TAG, "Service: " + name + " disconnected"); } }; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); doBind(); Log.i(TAG, "Started (UI Thread)"); // set content setContentView(R.layout.main); Resources res = getResources(); // Resource object to get Drawables TabHost tabHost = getTabHost(); // The activity TabHost ... add some tabs here.... tabHost.setCurrentTab(0); } private void doBind(){ Intent i = new Intent(this,myService.class); if( bindService(i, mServiceConn, 0 )){ Log.i(TAG, "Service bound"); } else { Log.e(TAG, "Service not bound"); } } } Then the service: public class myService extends Service { private String TAG = "myService"; private boolean mRunning = false; @Override public int onStartCommand(Intent intent, int flags, int startid) { Log.i(TAG,"Service start"); mRunning = true; Log.d(TAG,"Finished onStartCommand"); return START_STICKY; } /* * Called on service stop */ @Override public void onDestroy(){ Log.i(TAG,"onDestroy"); mRunning = false; super.onDestroy(); } @Override public IBinder onBind(Intent intent) { return mBinder; } boolean isRunning() { return mRunning; } /* * class for binding */ private final IBinder mBinder = new myBinder(); public class myBinder extends Binder { myService getService() { return myService.this; } } } bindService returns true, but onServiceConnection is never called (mService is always null, so I can't do something like mService.isRunning() ) The manifest entry for the service is just: <service android:name=".myService"></service> I was copying the code direct from the Android developers site, but I must have missed something.

  • Quartz.Net Windows Service Configure Logging

    - by Tarun Arora
    In this blog post I’ll be covering, Logging for Quartz.Net Windows Service 01 – Why doesn’t Quartz.Net Windows Service log by default 02 – Configuring Quartz.Net windows service for logging to eventlog, file, console, etc 03 – Results: Logging in action If you are new to Quartz.Net I would recommend going through, A brief Introduction to Quartz.net Walkthrough of Installing & Testing Quartz.Net as a Windows Service Writing & Scheduling your First HelloWorld job with Quartz.Net   01 – Why doesn’t Quartz.Net Windows Service log by default If you are trying to figure out why… The Quartz.Net windows service isn’t logging The Quartz.Net windows service isn’t writing anything to the event log The Quartz.Net windows service isn’t writing anything to a file How do I configure Quartz.Net windows service to use log4Net How do I change the level of logging for Quartz.Net Look no further, This blog post should help you answer these questions. Quartz.NET uses the Common.Logging framework for all of its logging needs. If you navigate to the directory where Quartz.Net Windows Service is installed (I have the service installed in C:\Program Files (x86)\Quartz.net, you can find out the location by looking at the properties of the service) and open ‘Quartz.Server.exe.config’ you’ll see that the Quartz.Net is already set up for logging to ConsoleAppender and EventLogAppender, but only ‘ConsoleAppender’ is set up as active. So, unless you have the console associated to the Quartz.Net service you won’t be able to see any logging. <log4net> <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender"> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%d [%t] %-5p %l - %m%n" /> </layout> </appender> <appender name="EventLogAppender" type="log4net.Appender.EventLogAppender"> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%d [%t] %-5p %l - %m%n" /> </layout> </appender> <root> <level value="INFO" /> <appender-ref ref="ConsoleAppender" /> <!-- uncomment to enable event log appending --> <!-- <appender-ref ref="EventLogAppender" /> --> </root> </log4net> Problem: In the configuration above Quartz.Net Windows Service only has ConsoleAppender active. So, no logging will be done to EventLog. More over the RollingFileAppender isn’t setup at all. So, Quartz.Net will not log to an application trace log file. 02 – Configuring Quartz.Net windows service for logging to eventlog, file, console, etc Let’s change this behaviour by changing the config file… In the below config file, I have added the RollingFileAppender. This will configure Quartz.Net service to write to a log file. (<appender name="GeneralLog" type="log4net.Appender.RollingFileAppender">) I have specified the location for the log file (<arg key="configFile" value="Trace/application.log.txt"/>) I have enabled the EventLogAppender and RollingFileAppender to be written to by Quartz. Net windows service Changed the default level of logging from ‘Info’ to ‘All’. This means all activity performed by Quartz.Net Windows service will be logged. You might want to tune this back to ‘Debug’ or ‘Info’ later as logging ‘All’ will produce too much data to the logs. (<level value="ALL"/>) Since I have changed the logging level to ‘All’, I have added applicationSetting to remove logging log4Net internal debugging. (<add key="log4net.Internal.Debug" value="false"/>) <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="quartz" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0,Culture=neutral, PublicKeyToken=b77a5c561934e089" /> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" /> <sectionGroup name="common"> <section name="logging" type="Common.Logging.ConfigurationSectionHandler, Common.Logging" /> </sectionGroup> </configSections> <common> <logging> <factoryAdapter type="Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4net"> <arg key="configType" value="INLINE" /> <arg key="configFile" value="Trace/application.log.txt"/> <arg key="level" value="ALL" /> </factoryAdapter> </logging> </common> <appSettings> <add key="log4net.Internal.Debug" value="false"/> </appSettings> <log4net> <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender"> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%d [%t] %-5p %l - %m%n" /> </layout> </appender> <appender name="EventLogAppender" type="log4net.Appender.EventLogAppender"> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%d [%t] %-5p %l - %m%n" /> </layout> </appender> <appender name="GeneralLog" type="log4net.Appender.RollingFileAppender"> <file value="Trace/application.log.txt"/> <appendToFile value="true"/> <maximumFileSize value="1024KB"/> <rollingStyle value="Size"/> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%d{HH:mm:ss} [%t] %-5p %c - %m%n"/> </layout> </appender> <root> <level value="ALL" /> <appender-ref ref="ConsoleAppender" /> <appender-ref ref="EventLogAppender" /> <appender-ref ref="GeneralLog"/> </root> </log4net> </configuration>   Note – Please ensure you restart the Quartz.Net Windows service for the config changes to be picked up by the service   03 – Results: Logging in action Once you start the Quartz.Net Windows Service up, the logging should be initiated to write all activities in the Console, EventLog and File… See screen shots below… Figure – Quartz.Net Windows Service logging all activity to the event log Figure – Quartz.Net Windows Service logging all activity to the application log file Where is the output from log4Net ConsoleAppender? As a default behaviour, the console isn't available in windows services, web services, windows forms. The output will simply be dismissed. Unless you are running the process interactively. Which you can do by firing up Quartz.Server.exe –i to see the output   This was fourth in the series of posts on enterprise scheduling using Quartz.net, in the next post I’ll be covering troubleshooting why a scheduled task hasn’t fired on Quartz.net windows service. All Quartz.Net specific blog posts can listed here. Thank you for taking the time out and reading this blog post.

  • postgresql service corrupt, how can i re-create service?

    - by pstanton
    Hi all, I recently was tricked into running one of those registry cleaner programs (RegistryBooster). It seemed to work fine until I tried to start my postgres service. For some reason, the 'path to executable' was no longer set on the service properties page, and obviously would not start without a path. How can I either fix the existing service or uninstall/ re-install just the service without re-installing postgres altogether? postgres 8.4 windows xp sp3

  • Windows Service Limit Crashes Services on Startup

    - by Paul Williams
    We have developed a custom Windows service in C# as part of a large Enterprise application. Our QA department tests multiple versions of this service. The QA lab has several (over 20) copies of this service installed on one Windows 2003 test box. Each copy is in its own folder and has a unique service name, though each executable file is named the same (OurWindowsService.exe, for example). Each service uses the same Windows credentials (a domain user). The purpose of this service is to handle MSMQ messages. The queued messages do all sorts of important stuff. For some reason, they can run only 5 of these services at a time. When we start a 6th, the service crashes on startup. For example, I can start #1, #2, #3, #4, and #5. When I start #6, it crashes. However, if I stop #1 and start #6, #6 runs fine, and now #1 fails to start. When the services crash, the following error appears in the Windows event log: Faulting application OurWindowsService.exe, version 5.40.1.1, faulting module kernel32.dll, version 5.2.3790.4480, fault address 0x0000bef7. I was able to use WinDbg to generate a postmortem dump file. The dump file revealed that the crash occurs trying to delay load SHLWAPI.dll: 0:000> kb100 ChildEBP RetAddr Args to Child 0012ece4 79037966 c06d007e 00000000 00000001 KERNEL32!RaiseException+0x53 0012ed4c 790099ba 00000008 0012ed08 7c82860c mscoree!__delayLoadHelper2+0x139 0012ed98 790075b1 001550c8 0012edac 0012fb34 mscoree!_tailMerge_**SHLWAPI_dll**+0xd 0012edb0 79007623 001550c8 0012edf8 0012edf4 mscoree!XMLGetVersionWithSupported+0x22 0012ee00 790069a4 aa06f1b0 00000000 000001fe mscoree!RuntimeRequest::GetRuntimeVersion+0x56 0012f478 790077aa 00000001 7903fb4c 0012fb34 mscoree!RuntimeRequest::ComputeVersionString+0x5bd 0012f89c 79007802 00000001 0012f8b4 7903fb4c mscoree!RuntimeRequest::FindVersionedRuntime+0x11c 0012f8b8 79007b19 00000001 00000000 aa06fa6c mscoree!RuntimeRequest::RequestRuntimeDll+0x2c 0012ffa4 79007c02 00000001 0012ffbc 00000000 mscoree!GetInstallation+0x72 0012ffc0 77e6f23b 00000000 00000000 7ffdf000 mscoree!_CorExeMain+0x12 0012fff0 00000000 79007bf0 00000000 78746341 KERNEL32!BaseProcessStart+0x23 I believe the error code handed to Kernel32.RaiseException, c06d007e, means Module Not Found, but I'm not certain. Does this sound familiar to anyone? Are we hitting some limit on the number of service instances on some file name? Does MSMQ dislike more than 5 listening services?

  • trouble setting up TreeViews in pygtk

    - by Chris H
    I've got some code in a class that extends gtk.TreeView, and this is the init method. I want to create a tree view that has 3 columns. A toggle button, a label, and a drop down box that the user can type stuff into. The code below works, except that the toggle button doesn't react to mouse clicks and the label and the ComboEntry aren't drawn. (So I guess you can say it doesn't work). I can add rows just fine however. #make storage enable/disable label user entry self.tv_store = gtk.TreeStore(gtk.ToggleButton, str, gtk.ComboBoxEntry) #make widget gtk.TreeView.__init__(self, self.tv_store) #make renderers self.buttonRenderer = gtk.CellRendererToggle() self.labelRenderer = gtk.CellRendererText() self.entryRenderer = gtk.CellRendererCombo() #make columns self.columnButton = gtk.TreeViewColumn('Enabled') self.columnButton.pack_start(self.buttonRenderer, False) self.columnLabel = gtk.TreeViewColumn('Label') self.columnLabel.pack_start(self.labelRenderer, False) self.columnEntry = gtk.TreeViewColumn('Data') self.columnEntry.pack_start(self.entryRenderer, True) self.append_column(self.columnButton) self.append_column(self.columnLabel) self.append_column(self.columnEntry) self.tmpButton = gtk.ToggleButton('example') self.tmpCombo = gtk.ComboBoxEntry(None) self.tv_store.insert(None, 0, [self.tmpButton, 'example label', self.tmpCombo]) thanks.

  • Calling webservice from WCF service

    - by Balaji
    I am having an issue consuming a webservice (c#.net) from a WCF service. The error i am getting is EndPointNotFoundException "TCP error code 10061: No connection could be made because the target machine actively refused it" I wrote a unit test to check if i could send a request to the web service and it worked fine [The unit test is using the same binding configuration as my WCF service] The web service and WCF service (client) have basichttp binding. Did anyone had similar kind of issue calling a webservice from a WCF service? The service Model section is as follows <system.serviceModel> <bindings> <basicHttpBinding> <binding name="DataService" closeTimeout="00:05:00" openTimeout="00:05:00" receiveTimeout="00:10:00" sendTimeout="00:05:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384"/> <security mode="None"> <transport clientCredentialType="None" proxyCredentialType="None" realm=""/> <message clientCredentialType="UserName" algorithmSuite="Default"/> </security> </binding> </basicHttpBinding> </bindings> <client> <endpoint address="http://10.22.33.67/Service/DataService.asmx" binding="basicHttpBinding" bindingConfiguration="DataService" contract="Service.DataService" name="DataService"/> </client> <services> <service name="TestToConsumeDataService.WCFHost.Service1" behaviorConfiguration="TestToConsumeDataService.WCFHost.Service1Behavior"> <!-- Service Endpoints --> <endpoint address="" binding="basicHttpBinding" contract="TestToConsumeDataService.WCFHost.IService1"> <!-- Upon deployment, the following identity element should be removed or replaced to reflect the identity under which the deployed service runs.

    Hey. I am trying to load an image for a custom tableViewCell. The code gets run from the CustomCell-class (CustomCell.h) from [cell performSelectorInBackground:@selector(loadImageFromURL:) withObject:[NSURL URLWithString:urlString]]; in the cellForRowAtIndexPath:-function.

  • Using Constraints on Hierarchical Data in a Self-Referential Table

    - by pbarney
    Suppose you have the following table, intended to represent hierarchical data: +--------+-------------+ | Field | Type | +--------+-------------+ | id | int(10) | | parent | int(10) | | name | varchar(45) | +--------+-------------+ The table is self-referential in that the parent_id refers to id. So you might have the following data: +----+--------+---------------+ | id | parent | name | +----+--------+---------------+ | 1 | 0 | fruit | | 2 | 0 | vegetable | | 3 | 1 | apple | | 4 | 1 | orange | | 5 | 3 | red delicious | | 6 | 3 | granny smith | | 7 | 3 | gala | +----+--------+---------------+ Using MySQL, I am trying to impose a (self-referential) foreign key constraint upon the data to update on cascades and prevent deletion of fruit if they have "children." So I used the following: CREATE TABLE `idtlp_main`.`fruit` ( `id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT, `parent` INT(10) UNSIGNED, `name` VARCHAR(45) NOT NULL, PRIMARY KEY (`id`), CONSTRAINT `fk_parent` FOREIGN KEY (`parent`) REFERENCES `fruit` (`id`) ON UPDATE CASCADE ON DELETE RESTRICT ) ENGINE = InnoDB; From what I understand, this should fit my requirements. (And parent must default to null to allow insertions, correct?) The problem is, if I change the id of a record, it will not cascade: Cannot delete or update a parent row: a foreign key constraint fails (`iddoc_main`.`fruit`, CONSTRAINT `fk_parent` FOREIGN KEY (`parent`) REFERENCES `fruit` (`id`) ON UPDATE CASCADE) What am I missing? Feel free to correct me if my terminology is screwed up... I'm new to constraints.

  • 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.
