  • Access Control Service: Walkthrough Videos of Web Application, SOAP, REST and Silverlight Integration

    - by Your DisplayName here!
    Over the weekend I worked a little more on my ACS2 sample. Instead of writing it all down, I decided to quickly record four short videos that cover the relevant features and code. Have fun ;) Part 1 – Overview This video does a quick walkthrough of the solution and shows the web application part. This includes driving the sign in UI via JavaScript (thanks Matias) as well as the registration logic I wrote about here. watch Part 2 – SOAP Service and Client The sample app also exposes a WCF SOAP service. This video shows how to wire up the service to ACS and hows how to create a client that first requests a token from an IdP and then sends this token to ACS. watch Part 3 – REST Service and Client This part shows how to set up a WCF REST service that consumes SWT tokens from ACS. Unfortunately there is currently no standard WIF plumbing for REST. For the service integration I had to combine a lot of code from different sources (kzu, zulfiq) as well as the WIF SDK and OAuth CTPs together. But it is working. watch Part 4 – Silverlight and Web Identity Integration This part took by far the most time to write. The Silverlight Client shows ho to sign in to the application using a registered identity provider (including web identities) and using the resulting SWT token to call our REST service. This is designed to be a desktop (OOB) client application (thanks to Jörg for the UI magic). watch code download

  • Set and Verify the Retention Value for Change Data Capture

    - by AllenMWhite
    Last summer I set up Change Data Capture for a client to track changes to their application database to apply those changes to their data warehouse. The client had some issues a short while back and felt they needed to increase the retention period from the default 3 days to 5 days. I ran this query to make that change: sp_cdc_change_job @job_type='cleanup', @retention=7200 The value 7200 represents the number of minutes in a period of 5 days. All was well, but they recently asked how they can verify...(read more)

  • Detecting right-click on XAML GridView control item

    - by mbrit
    Leaving aside why you would ever want to do this in a touch-centric world, here's how you tell if the right-mouse button has been clicked on a GridView in XAML/WinRT/Metro-style. You have to retrieve a point relative to the UI element you're in, and then query its properties. void itemGridView_PointerPressed(object sender, PointerRoutedEventArgs e) { if (e.GetCurrentPoint(this).Properties.IsRightButtonPressed) { this.BottomAppBar.IsOpen = true; } } (The reason why you might want to do this can be explained by looking at any of the built-in Win8 apps. You can right-click any of the items on any list to bring up a context-sensitive AppBar.)

  • Allow non-sudo group to control Upstart job

    - by Angle O'Saxon
    I'm trying to set up an Upstart job to run on system startup, and that can also be started/stopped by members of a group other than sudo. With a previous version, I usedupdate-rc.d and scripts stored in /etc/init.d/ to get this working by adding %Group ALL = NOPASSWD: /etc/init.d/scriptname to my sudoers file, but I can't seem to get an equivalent working for Upstart. I tried adding %Group ALL = NOPASSWD: /sbin/initctl start jobname to the sudoers file, but trying to run the command start jobname produces this error: start: Rejected send message, 1 matched rules; type="method_call", sender=":1.21" (uid=1000 pid=5148 comm="start jobname " interface="com.ubuntu.Upstart0_6.Job" member="Start" error name="(unset)" requested_reply="0" destination="com.ubuntu.Upstart" (uid=0 pid=1 comm="/sbin/init") As near as I can tell, that's a complaint about how my user account isn't given the power to send 'Start' messages in the D-Bus config file for Upstart. I haven't been able to actually find any information on how to edit that file to give a group permission to access a specific service--does such an option exist? Is there a way to edit the Sudoers file so I can run the job without editing the config file? Am I better off just sticking with the previous version?

  • Structuring Access Control In Hierarchical Object Graph

    - by SB2055
    I have a Folder entity that can be Moderated by users. Folders can contain other folders. So I may have a structure like this: Folder 1 Folder 2 Folder 3 Folder 4 I have to decide how to implement Moderation for this entity. I've come up with two options: Option 1 When the user is given moderation privileges to Folder 1, define a moderator relationship between Folder 1 and User 1. No other relationships are added to the db. To determine if the user can moderate Folder 3, I check and see if User 1 is the moderator of any parent folders. This seems to alleviate some of the complexity of handling updates / moved entities / additions under Folder 1 after the relationship has been defined, and reverting the relationship means I only have to deal with one entity. Option 2 When the user is given moderation privileges to Folder 1, define a new relationship between User 1 and Folder 1, and all child entities down to the grandest of grandchildren when the relationship is created, and if it's ever removed, iterate back down the graph to remove the relationship. If I add something under Folder 2 after this relationship has been made, I just copy all Moderators into the new Entity. But when I need to show only the top-level Folders that a user is Moderating, I need to query all folders that have a parent folder that the user does not moderate, as opposed to option 1, where I just query any items that the user is moderating. Thoughts I think it comes down to determining if users will be querying for all parent items more than they'll be querying child items... if so, then option 1 seems better. But I'm not sure. Is either approach better than the other? Why? Or is there another approach that's better than both? I'm using Entity Framework in case it matters.

  • Best practice? - Array/Dictionary as a Core Data Entity Attribute

    - by Run Loop
    I am new to Core Data. I have noticed that collection types are not available as attribute types and would like to know what the most efficient way is of storing array/dictionary type data as an attribute (e.g. the elements that make up an address like street, city, etc. does not require a separate entity and is more conveniently stored as a dictionary/array than separate attributes/fields). Thank you.

  • Which has a faster data transfer rate? WIFI (tablet or cell phone, not LTE) or MicroSD (Class 10)?

    - by techaddict
    Which of the two methods of dta transfer trasfers data at a faster rate for smartphones and tablets? Standard WIFI, or MicroSD Cards? I wonder if it would be actually faster to access data on external storage then it would be to have the MicroSD card in my smartphone or tablet. Currently I have a class 10 32GB MicroSD card in my cell phone. I am looking to get the new Google Nexus tablet but it does not offer expandable internal storage. I wonder if that's really a detriment; because if WIFI is faster than MicroSD, then it would matter almost none at all that you couldn't expand the storage internally. If the case is that WIFI is faster, and people caught onto this, then people could save a lot of money on lower memory ipads/iphones/ipods, tablets, and smartphones!

  • Control Parameters and DropDownList Text

    - by Bunch
    This is something that I rarely need to do, grab a DropDownList’s selected item’s text for use in a datasource’s ControlParameter. To allow for this use SelectedItem.Text instead of the more common SelectedValue for the PropertyName. <asp:ControlParameter ControlID="ddlStuff" Name="stuffName" Type="String" PropertyName="SelectedItem.Text" /> The reason for using this is for text comparison. On rare occasions you may need to check the text against a list where the SelectedValue just does not help. Technorati Tags: ASP.Net

  • No event is firing when placing a custom data bound control in DataRepeater control in Windows forms

    - by Remo
    Hi, Custom events in a custom data bound control are not firing in DataRepeater control. When I debug it I found that the DataRepeater Control recreates the control using Activator.CreateInstance and Copies the Properties and Events. In my case copying events doesn't copy the custom events that I hooked in. For example public class MyClass : Control { public event EventHandler MyEvent; protected virtual void OnMyEvent() { if(this.MyEvent != null) { this.MyEvent(this,EventArgs.Empty); } } private int selectedIndex= -1; public int SelectedIndex { get { return this.selectedIndex; } set { if(this.selectedIndex != value) { this.selectedIndex = value; this.OnMyEvent(); } } } // // DataBinding stuff goes here // } public Form1() { InitialiseComponent(); ArrayList list = new ArrayList(); list.Add("one"); this.dataRepeater1.DataSource = list; // One Repeater MyClass test = new Myclass(); test.DataSource = GetDataTable(); this.dataRepeater1.ItemTemplate.Controls.Add(test); test.MyEvent +=new EventHandler(test_MyEvent); } // This Event should fire when selected index of Datatable is changed and is firing when placed directly in the form and not firing when place in DataRepeater control/////////////////////// private void test_MyEvent(object sender, EventArgss e) { // This event is not fired/////////////////////// } private DataTable GetDataTable() { ..// Create a data Table and return } Any help Appreciated. Thanks,

  • Let&rsquo;s keep informed with &ldquo;Data Explorer&rdquo;

    - by Luca Zavarella
    At Pass Summit 2011 a new project was announced. It’s a Microsoft SQL Azure Lab and its codename is Microsoft “Data Explorer”. According to the official blog (http://blogs.msdn.com/b/dataexplorer/), this new tool provides an innovative way to acquire new knowledge from the data that interest you. In a nutshell, Data Explorer allows you to combine data from multiple sources, to publish and share the result. In addition, you can generate data streams in the RESTful open format (Open Data Protocol), and they can then be used by other applications. Nonetheless we can still use Excel or PowerPivot to analyze the results. Sources can be varied: Excel spreadsheets, text files, databases, Windows Azure Marketplace, etc.. For those who are not familiar with this resource, I strongly suggest you to keep an eye on the data services available to the Marketplace: https://datamarket.azure.com/browse/Data To tell the truth, as I read the above blog post, I was tempted to think of the Data Explorer as a "SSIS on Azure" addressed to the Power User. In fact, reading the response from Tim Mallalieu (Group Program Manager of Data Explorer) to the comment made to his post, I had a positive response to my first impression: “…we originally thinking of ourselves as Self-Service ETL. As we talked to more folks and started partnering with other teams we realized that would be an area that we can add value but that there were more opportunities emerging.” The typical operations of the ETL phase ( processing and organization of data in different formats) can be obtained thanks to Data Explorer Mashup. This is an image of the tool: The flexibility in the manipulation of information is given by Data Explorer Formula Language. This is a formula-based Excel-style specific language: Anyone wishing to know more can check the project page in addition to aforementioned blog: http://www.microsoft.com/en-us/sqlazurelabs/labs/dataexplorer.aspx In light of this new project, there is no doubt about the intention of Microsoft to get closer and closer to the Power User, providing him flexible and very easy to use tools for data analysis. The prime example of this is PowerPivot. The question that remains is always the same: having in a company more Power User will implicitly mean having different data models representing the same reality. But this would inevitably lead to anarchical data management... What do you think about that?

  • How do i get the data from a surveillance camera to a storage i can stream from?

    - by radbyx
    Hi my sisters house was robbed chrismas evening :( I talked with her about making a surveillance system for her. The idea is to have a system that detects intruders and then send a SMS to you while streaming it to a private website. The hard part: How and where do I storage the data from the camera so it's streamable? I think i can manage to do the streaming, website and SMS server, but i need the data (fundamentation).
