  • How to create a Task Scheduler App.

    - by Mike
    I have been task with (ha) creating an application that will allow the users to schedule a command line app we have with a parameter. So the command line app takes an xml and "runs it" So bottom line I either need to create a windows service or learn how to interact with the Task Scheduler service already running on the box (version 1 Xp /2003) At first I though it would be easy have a service run and when a job is submitted, calculate the time between now and run and set up a timer to wait that amount of time. This is better then checking every minute if it's time to run. Were I hit a wall is I relized I do not know how to communicate with a running windows service. Except maybe create a file with details and have the service with a file watcher to load the file and modify the schedule. So the underlying questions are how can I execute this psedo code from client serviceThatIsRunning.Add(Job) Or ineracting with the task schedule or creating .job files using c# 3.5

  • Silverlight 4 RIA does not return anything using DomainContext

    - by Savvas Sopiadis
    Hi everybody! Just learning Silverlight 4/RIA and i 'm stuck in a weird problem: setup an ASP.NET MVC project as the project hosting the Domain service. In this i tried to get data from the Domain Service which worked fine (i'm using a repository in it). Now i tried to setup a SL4 project. I though i do it the MVVM-way, so i decided to setup a ViewModel Class with the following code: public class ViewModel { OrganizationDomainContext dsCtxt = new OrganizationDomainContext(); public ViewModel() { EntityQuery<Culture> query = from cu in dsCtxt.GetAllCulturesQuery() select cu; LoadOperation<Culture> lo = dsCtxt.Load(query); } } The crazy thing about this is .. it doesn't return anything!!! What am i missing here? Thanks in advance

  • Amazon EC2 EBS automatic backup one-liner works manually but not from cron

    - by dan
    I am trying to implement an automatic backup system for my EBS on Amazon AWS. When I run this command as ec2-user: /opt/aws/bin/ec2-create-snapshot --region us-east-1 -K /home/ec2-user/pk.pem -C /home/ec2-user/cert.pem -d "vol-******** snapshot" vol-******** everything works fine. But if I add this line into /etc/crontab and restart the crond service: 15 12 * * * ec2-user /opt/aws/bin/ec2-create-snapshot --region us-east-1 -K /home/ec2-user/pk.pem -C /home/ec2-user/cert.pem -d "vol-******** snapshot" vol-******** that doesn't work. I checked var/log/cron and there is this line, therefore the command gets executed: Dec 13 12:15:01 ip-10-204-111-94 CROND[4201]: (ec2-user) CMD (/opt/aws/bin/ec2-create-snapshot --region us-east-1 -K /home/ec2-user/pk.pem -C /home/ec2-user/cert.pem -d "vol-******** snapshot" vol-******** ) Can you please help me to troubleshoot the problem? I guess is some environment problem - maybe the lack of some variable. If that's the case I don't know what to do about it. Thanks.

  • Issues with Rails, Amazon S3, and protected URLs

    - by Shpigford
    So I followed this little tutorial about protecting downloads of files that are uploaded to Amazon S3 with Paperclip. When I've developed locally, it's worked fine, but since pushing the exact same code to a production server...I now get this error from Amazon when I try to access the files: <Error> <Code>InvalidArgument</Code> <Message>Either the Signature query string parameter or the Authorization header should be specified, not both</Message> <ArgumentValue>Basic dGVjaHVrdWxlbGU6ZWxlbHVrdWhjZXQ=</ArgumentValue> <ArgumentName>Authorization</ArgumentName> <RequestId>F6E455857C54F95A</RequestId> <HostId>X4QA2pw9wpHtJtJ2T8qxCyINjq4PLHQVF4VrlYjpX7Ayh694BgQprh5p8H7NRCAt</HostId> </Error> Example URL: http://s3.amazonaws.com/media.example.com/assets/videos/1/original.mov?AWSAccessKeyId=MY_ACCESS_KEY&Expires=1271972624&Signature=7wWH2WYHPO0o9szwPJbimUMqAig%3D That URL is generated using AWS::S3::S3Object.url_for using the aws-s3 gem. So...not even sure where to start. The fact that it works fine when the app is running locally but not when in production really doesn't make sense. The production server is running Ubuntu 8.04.4 LTS (Hardy).

  • Hadoop or Hadoop Streaming for MapReduce on AWS

    - by aeolist
    I'm about to start a mapreduce project which will run on AWS and I am presented with a choice, to either use Java or C++. I understand that writing the project in Java would make more functionality available to me, however C++ could pull it off too, through Hadoop Streaming. Mind you, I have little background in either language. A similar project has been done in C++ and the code is available to me. So my question: is this extra functionality available through AWS or is it only relevant if you have more control over the cloud? Is there anything else I should bear in mind in order to make a decision, like availability of plugins for hadoop that work better with one language or the other? Thanks in advance

  • WCF Security in a Windows Service

    - by Alphonso
    I have a WCF service which can run as Console App and a Windows Service. I have recently copied the console app up to a W2K3 server with the following security settings: <wsHttpBinding> <binding name="ServiceBinding_Security" transactionFlow="true" > <security mode="TransportWithMessageCredential" > <message clientCredentialType="UserName" /> </security> </binding> </wsHttpBinding> <serviceCredentials> <userNameAuthentication userNamePasswordValidationMode="Custom" customUserNamePasswordValidatorType="Common.CustomUserNameValidator, Common" /> </serviceCredentials> Security works fine with no problems. I have exactly the same code, but running in a windows service and I get the following error when I try to call any of the methods from a client: System.ServiceModel.Security.MessageSecurityException was unhandled Message="An unsecured or incorrectly secured fault was received from the other party. See the inner FaultException for the fault code and detail." Source="mscorlib" StackTrace: Server stack trace: at System.ServiceModel.Channels.SecurityChannelFactory`1.SecurityRequestChannel.ProcessReply(Message reply, SecurityProtocolCorrelationState correlationState, TimeSpan timeout) ...... (lots of stacktrace info - not very useful) InnerException: System.ServiceModel.FaultException Message="An error occurred when verifying security for the message." The exception tells me nothing. I'm assuming that it has something to do with acces to system resources from the Windows Service. I've tried running it under the same account as the console app, but no luck. Does anyone have any ideas?

  • What happens to the output to a log4net console appender in a Windows service?

    - by uriDium
    I have a console project that I have been working on. I added log4net to handle all my logging. In some places I have made use of the console appender. When I turn this application into a Windows Service should I just remove the console appender or what happens to that output? Does it just get lost? I would like to keep it if all possible because if I run it straight from the command prompt I would like to see the console output to help debug things.

  • Is it possible to deploy a SOAP server with Axis without using WSDD?

    - by Alceu Costa
    In the project I am working I have deployed a SOAP server using Deployment Descriptors (WSDD) files. To do that a webserver (e.g tomcat, jetty) is started and then the following command is executed: java -cp %AXISCLASSPATH% org.apache.axis.client.AdminClient deploy.wsdd What I need is to skip the above command to avoid a call to the Axis AdminClient. Is it possible to deploy my webservice as war file? Note: A solution with JWS can't be used due to its limitations.

  • Knowing the selections made on a 'multichooser' box in a mechanical turk hit (using Command Line Too

    - by gveda
    Hi All, I am new to Amazon Mechanical Turk, and wanted to create a hit with a qualification task. I am using the command line tools interface. One of the questions in my qualification task involves users selecting a number of options. I use a 'multichooser' selection type. Now I want to grade the responses based on the selections, where each selection has a different score. So for example, s1 has a score of 5, s2 of 10, s3 of 6, and so on. If the user selects s1 and s3, he/she gets a score of 11. Unfortunately, doing something like the following does not work: <AnswerOption> <SelectionIdentifier>s1</SelectionIdentifier> <AnswerScore>5</AnswerScore> </AnswerOption> <AnswerOption> <SelectionIdentifier>s2</SelectionIdentifier> <AnswerScore>10</AnswerScore> </AnswerOption> <AnswerOption> <SelectionIdentifier>s3</SelectionIdentifier> <AnswerScore>6</AnswerScore> </AnswerOption> If I do this, when I select multiple things, I get a score of 0. If I select only one option, say s1, then I get the appropriate score. Can you please help me on how to go about this? I could ask the same question 5 times with the same options, but then users might choose the same answer multiple times - something I wish to avoid. Thanks! Gaurav

  • How to add an image to an SSRS report with a dynamic url?

    - by jrummell
    I'm trying to add an image to a report. The image src url is an IHttpHandler that takes a few query string parameters. Here's an example: <img src="Image.ashx?item=1234567890&lot=asdf&width=50" alt=""/> I added an Image to a cell and then set Source to External and Value to the following expression: ="Image.ashx?item="+Fields!ItemID.Value+"&lot="+Fields!LotID.Value+"&width=50" But when I view the report, it renders the image html as: <IMG SRC="" /> What am I missing? Update Even if I set Value to "image.jpg" it still renders an empty src attribute. I'm not sure if it makes a difference, but I'm using this with a VS 2008 ReportViewer control in Remote processing mode. Update I was able to get the images to display in the Report Designer (VS 2005) with an absolute path (http://server/path/to/http/handler). But they didn't display on the Report Manager website. I even set up an Unattended Execution Account that has access to the external URLs.

    Hi, for creating a columns I worked on this code . and for creating document library Lists listService = new Lists(); listService.PreAuthenticate = true; listService.Credentials = new NetworkCredential(username,password,domain; String url = "http://YourServer/SiteName/"; listService.Url = url @ + /_vti_bin/lists.asmx"; XmlNode ndList = listService.AddList(NewListName, "Description", 101); Both are working successfully. But Problem i am facing is: New Columns and document library are not visible. I tried with comparing Field Value of Both Visible and No-Visible types. Difference i found is : Visible (Created Manually) doesn't contain Version value. were as i am creating have it. Can you help me out in this? EDIT: I checked contents of ndList node, List is created and it is visible on my UI. but on sharepoint it should be listed in 'Document' tab where default 'Shared Documents' library is shown. If i click on 'Documents' then we can also see all lib created by this code. Visible means library displayed under 'Documents' tab

  • JAX-WS client with AXIS server; namespace problem?

    - by Jarno
    I'm having a problem related to JAX-WS and AXIS. JAX-WS (2.1.7) as a client, Axis (1.4.x) as server. Everything works OK, but the response can't be read to Java. Response: <?xml version="1.0" encoding="UTF-8"?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <soapenv:Body> <ns1:myserviceResponse soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:ns1="http://my/service"> <ns1:myserviceReturn xsi:type="xsd:string">responsestring</ns1:myserviceReturn> </ns1:myserviceResponse> </soapenv:Body> </soapenv:Envelope> The problem is that if "ns1:"-namespace declaration is removed from myserviceReturn, JAX-WS is able to return else than null. Does anyone have a clue how to force JAX-WS to ignore namespaces, how to modify SOAP response manually to exclude "ns1", or other ideas for this kind of problem? Any help is appreciated!!!

  • Should I allow sending complete structures when using PUT for updates in a REST API or not?

    - by dafmetal
    I am designing a REST API and I wonder what the recommended way to handle updates to resources would be. More specifically, I would allow updates through a PUT on the resource, but what should I allow in the body of the PUT request? Always the complete structure of the resource? Always the subpart (that changed) of the structure of the resource? A combination of both? For example, take the resource http://example.org/api/v1/dogs/packs/p1. A GET on this resource would give the following: Request: GET http://example.org/api/v1/dogs/packs/p1 Accept: application/xml Response: <pack> <owner>David</owner> <dogs> <dog> <name>Woofer</name> <breed>Basset Hound</breed> </dog> <dog> <name>Mr. Bones</name> <breed>Basset Hound</breed> </dog> </dogs> </pack> Suppose I want to add a dog (Sniffers the Basset Hound) to the pack, would I support either: Request: PUT http://example.org/api/v1/dogs/packs/p1 <dog> <name>Sniffers</name> <breed>Basset Hound</breed> </dog> Response: HTTP/1.1 200 OK or Request: PUT http://example.org/api/v1/dogs/packs/p1 <pack> <owner>David</owner> <dogs> <dog> <name>Woofer</name> <breed>Basset Hound</breed> </dog> <dog> <name>Mr. Bones</name> <breed>Basset Hound</breed> </dog> <dog> <name>Sniffers</name> <breed>Basset Hound</breed> </dog> </dogs> </pack> Response: HTTP/1.1 200 OK or both? If supporting updates through subsections of the structure is recommended, how would I handle deletes (such as when a dog dies)? Through query parameters?
