  • Emulate terminal services

    - by cloudstrif3
    Hello, I am a seasoned Delphi developer and would like to create something like seamless terminal services where an application is executed on a server but appears on the the desktop of the client. To someone working on the server i don't want them to see the remote application running (except if they looked in at the list of running processes). Im lost as to how to go about this, where to start, how to get an application to render to a surface other than the servers desktop. Any suggestions would be most appreciated.

    - by jfar
    I'm looking for the full list of supported linq extension methods that are compatible with WCF Data Services. By trial and error I've found First() and Single() aren't supported, any others? This gives me a pretty good idea of whats supported, I just don't know whats actually translated via the IQueryProvider.

  • Registration with profile picture using services in Drupal

    - by Fran Ruano
    I've been trying to upload a user profile picture during the user registration using Service 3 and so far I haven't had any luck. I tested passing a hard coded fid in the field "picture" and also tried to pass the fields "filemime", "filename", etc. and it didn't work neither. Any idea about what fields I need to populate? I guess it must be related to this post Using Drupal Services and DIOS SDK for setting user picture in iOS app but it doesn't have and answer neither.

  • Accessing Sharepoint tasks via web services?

    - by scooterhanson
    I've looked at a lot of the previous questions asked about sharepoint and accessing objects via web-services, and I am pretty convinced that tasks can be accessed through the Lists interface. Can anybody please verify this for me? Also, if anyone has any examples of this I would be very grateful. I'm not a Sharepoint guy but I need to connect to an instance just to retrieve task objects.

  • SQL SERVER – Advanced Data Quality Services with Melissa Data – Azure Data Market

    - by pinaldave
    There has been much fanfare over the new SQL Server 2012, and especially around its new companion product Data Quality Services (DQS). Among the many new features is the addition of this integrated knowledge-driven product that enables data stewards everywhere to profile, match, and cleanse data. In addition to the homegrown rules that data stewards can design and implement, there are also connectors to third party providers that are hosted in the Azure Datamarket marketplace.  In this review, I leverage SQL Server 2012 Data Quality Services, and proceed to subscribe to a third party data cleansing product through the Datamarket to showcase this unique capability. Crucial Questions For the purposes of the review, I used a database I had in an Excel spreadsheet with name and address information. Upon a cursory inspection, there are miscellaneous problems with these records; some addresses are missing ZIP codes, others missing a city, and some records are slightly misspelled or have unparsed suites. With DQS, I can easily add a knowledge base to help standardize my values, such as for state abbreviations. But how do I know that my address is correct? And if my address is not correct, what should it be corrected to? The answer lies in a third party knowledge base by the acknowledged USPS certified address accuracy experts at Melissa Data. Reference Data Services Within DQS there is a handy feature to actually add reference data from many different third-party Reference Data Services (RDS) vendors. DQS simplifies the processes of cleansing, standardizing, and enriching data through custom rules and through service providers from the Azure Datamarket. A quick jump over to the Datamarket site shows me that there are a handful of providers that offer data directly through Data Quality Services. Upon subscribing to these services, one can attach a DQS domain or composite domain (fields in a record) to a reference data service provider, and begin using it to cleanse, standardize, and enrich that data. Besides what I am looking for (address correction and enrichment), it is possible to subscribe to a host of other services including geocoding, IP address reference, phone checking and enrichment, as well as name parsing, standardization, and genderization.  These capabilities extend the data quality that DQS has natively by quite a bit. For my current address correction review, I needed to first sign up to a reference data provider on the Azure Data Market site. For this example, I used Melissa Data’s Address Check Service. They offer free one-month trials, so if you wish to follow along, or need to add address quality to your own data, I encourage you to sign up with them. Once I subscribed to the desired Reference Data Provider, I navigated my browser to the Account Keys within My Account to view the generated account key, which I then inserted into the DQS Client – Configuration under the Administration area. Step by Step to Guide That was all it took to hook in the subscribed provider -Melissa Data- directly to my DQS Client. The next step was for me to attach and map in my Reference Data from the newly acquired reference data provider, to a domain in my knowledge base. On the DQS Client home screen, I selected “New Knowledge Base” under Knowledge Base Management on the left-hand side of the home screen. Under New Knowledge Base, I typed a Name and description of my new knowledge base, then proceeded to the Domain Management screen. Here I established a series of domains (fields) and then linked them all together as a composite domain (record set). Using the Create Domain button, I created the following domains according to the fields in my incoming data: Name Address Suite City State Zip I added a Suite column in my domain because Melissa Data has the ability to return missing Suites based on last name or company. And that’s a great benefit of using these third party providers, as they have data that the data steward would not normally have access to. The bottom line is, with these third party data providers, I can actually improve my data. Next, I created a composite domain (fulladdress) and added the (field) domains into the composite domain. This essentially groups our address fields together in a record to facilitate the full address cleansing they perform. I then selected my newly created composite domain and under the Reference Data tab, added my third party reference data provider –Melissa Data’s Address Check- and mapped in each domain that I had to the provider’s Schema. Now that my composite domain has been married to the Reference Data service, I can take the newly published knowledge base and create a project to cleanse and enrich my data. My next task was to create a new Data Quality project, mapping in my data source and matching it to the appropriate domain column, and then kick off the verification process. It took just a few minutes with some progress indicators indicating that it was working. When the process concluded, there was a helpful set of tabs that place the response records into categories: suggested; new; invalid; corrected (automatically); and correct. Accepting the suggestions provided by  Melissa Data allowed me to clean up all the records and flag the invalid ones. It is very apparent that DQS makes address data quality simplistic for any IT professional. Final Note As I have shown, DQS makes data quality very easy. Within minutes I was able to set up a data cleansing and enrichment routine within my data quality project, and ensure that my address data was clean, verified, and standardized against real reference data. As reviewed here, it’s easy to see how both SQL Server 2012 and DQS work to take what used to require a highly skilled developer, and empower an average business or database person to consume external services and clean data.

  • The Open Data Protocol

    - by Bobby Diaz
    Well, day 2 of the MIX10 conference did not disappoint.  The keynote speakers introduced the preview release of IE9, which looks really cool and quick, and Visual Studio 2010 RC that is scheduled to RTM on April 12th.  It seemed to have a lot of improvements aimed at making developers more productive.  Here are the current links to these two offerings: Internet Explorer 9 – Platform Preview Visual Studio 2010 and .NET 4 – Release Candidate While both of these were interesting, the demos that really blew me away today centered around the work being done with The Open Data Protocol, or OData for short!  OData is a recommended standard being pushed by Microsoft that uses a REST based interface to interact with various types of data in a uniform manner.  Data producers then provide the data to consumer in either ATOM or JSON formats as requested by the client application. The OData SDK contains client and server libraries for many of the popular languages in use today, including .NET, Java, PHP, Objective C and JavaScript, so you consume or even produce your own OData services.  More information can be found using the following links: OData.org How to navigate an OData compliant service Query Functions (WCF Data Services) Netflix has made available one of the first live OData services by exposing their entire movie catalog.  You can browse and query using URLs similar to the following: http://odata.netflix.com/ http://odata.netflix.com/Catalog/Genres('Horror')/CatalogTitles http://odata.netflix.com/Catalog/CatalogTitles?$filter=startswith(Title/Regular,%20'Star%20Wars')&$orderby=Title/Regular So now I just need to find an excuse reason to start using OData in a real project! Enjoy!

  • When you add a new node to a cluster, what do you do to the default services?

    - by Tom
    Everytime I acquire a new server or reload an existing server (CentOS 6.X) I have to decide what services to leave running in chkconfig. It seems the datacenter staff aren't using a single edition of CentOS and sometimes the default services running are different. I'm always inclined to turn off every service I've never heard of but then I think, if it's not broken don't fix it. How do you deal with the default services in a new installation?

  • Google play game services and Facebook integration in one game

    - by Ineentho
    We are creating a cross platform game for iOS and Android. We have thought about how and with which services we should integrate achievements and scoreboards with. For the iOS part, we are pretty sure that this how we want to do, in order from when the user opens the app for the first time: Connect with Game Center (Should be automatic, the user shouldn't even notice?) We will also get the players nickname for public scoreboards here. Ask if the user wants to connect with Facebook so that we can compare the players highscores with their friends. We could add Google play game services there as well, but I don't feel like that adds anything to the experience for the end user. Now comes the tricky part: Android We thought that we could do just like for iOS, except that we replace Game Center with Google Play Game Services. However, unlike Game Center, Game Services will ask the user to log in to their Google+ account and allow us to access their account. So now, what we have is a double login, first with Google+ and then with Facebook. What will users think about that? Should we scrap Play Services entirely and just ask the user for a nickname within our app and user Facebook for achievements?

  • Common Areas For Securing Web Services

    The only way to truly keep a web service secure is to host it on a web server and then turn off the server. In real life no web service is 100% secure but there are methodologies for increasing the security around web services. In order for consumers of a web service they must adhere to the service’s Service-Level Agreement (SLA).  An SLA is a digital contract between a web service and its consumer. This contract defines what methods and protocols must be used to access the web service along with the defined data formats for sending and receiving data through the service. If either part does not abide by the contract then the service will not be accessible for consumption. Common areas for securing web services: Universal Discovery Description Integration  (UDDI) Web Service Description Language  (WSDL) Application Level Network Level “UDDI is a specification for maintaining standardized directories of information about web services, recording their capabilities, location and requirements in a universally recognized format.” (UDDI, 2010) WSDL on the other hand is a standardized format for defining a web service. A WSDL describes the allowable methods for accessing the web service along with what operations it performs. Web services in the Application Level can control access to what data is available by implementing its own security through various methodologies but the most common method is to have a consumer pass in a token along with a system identifier so that they system can validate the users access to any data or actions that they may be requesting. Security restrictions can also be applied to the host web server of the service by restricting access to the site by IP address or login credentials. Furthermore, companies can also block access to a service by using firewall rules and only allowing access to specific services on certain ports coming from specific IP addresses. This last methodology may require consumers to obtain a static IP address and then register it with the web service host so that they will be provide access to the information they wish to obtain. It is important to note that these areas can be secured in any combination based on the security level tolerance dictated by the publisher of the web service. This being said, the bare minimum security implantation must be in the Application Level within the web service itself. Typically I create a security layer within a web services exposed Internet that requires a consumer identifier and a consumer token. This information is then used to authenticate the requesting consumer before the actual request is performed. Refernece:UDDI. (2010).

  • Beginners Guide to Client Application Services

    - by mbcrump
    What is it? Client application services make it easy for you to create Windows-based applications that use the ASP.NET AJAX login, roles, and profile application services included in the Microsoft ASP.NET 2.0 AJAX Extensions. These services enable multiple Web and Windows-based applications to share user information and user-management functionality from a single server.   What can you do with it? Authenticate a user. You can use the authentication service to verify a user's identity. Determine the role or roles of an authenticated user. You can use the roles service to change the user interface of your application depending on the user's role. For example, you can provide additional features for users who are in an administrator role. Store and access per-user application settings located on the server. You can use the Web settings service (also known as the profile service) to share settings across multiple applications and locations. Client application services take advantage of the Web services extensibility model through client service providers that you can specify in your application configuration files. These service providers include offline functionality that uses a local cache for authentication, roles, and settings data when a network connection is unavailable. Give me an example of where I would use this! Sharing login and user role information between a Windows Form application and a ASP.NET application. How do I configure it? Click Here
