How to check if a cdrom is in the tray remotely (via ssh)?

- by adempewolff

I have a server running Ubuntu 10.04 (it's on the other side of the world and I haven't built up the wherewithal to upgrade it remotely yet) and I have been told that there is a CD in one of it's two CD drives. I want to rip an image of the cd and then download it to my local computer (I don't need help with either of these steps). However, I cannot seem to confirm whether or not there actually is a CD in the drive as I was told. It did not automatically mount anywhere (which I'm thinking might just be a result of it being a headless server not running X, nautilus, or any of the other nice user friendly things). There are two CD drives connected via SCSI: austin@austinvpn:/proc/scsi$ cat /proc/scsi/scsi Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: ATA Model: WDC WD400EB-75CP Rev: 06.0 Type: Direct-Access ANSI SCSI revision: 05 Host: scsi1 Channel: 00 Id: 00 Lun: 00 Vendor: Lite-On Model: LTN486S 48x Max Rev: YDS6 Type: CD-ROM ANSI SCSI revision: 05 Host: scsi1 Channel: 00 Id: 01 Lun: 00 Vendor: SAMSUNG Model: CD-R/RW SW-248F Rev: R602 Type: CD-ROM ANSI SCSI revision: 05 However when I try mounting either of these devices (and every other device that could possibly be the cd-drive), it says no medium found: austin@austinvpn:/proc/scsi$ sudo mount -t iso9660 /dev/scd1 /cdrom mount: no medium found on /dev/sr1 austin@austinvpn:/proc/scsi$ sudo mount -t iso9660 /dev/scd0 /cdrom mount: no medium found on /dev/sr0 austin@austinvpn:/proc/scsi$ sudo mount -t iso9660 /dev/cdrom /cdrom mount: no medium found on /dev/sr1 austin@austinvpn:/proc/scsi$ sudo mount -t iso9660 /dev/cdrom1 /cdrom mount: no medium found on /dev/sr0 austin@austinvpn:/proc/scsi$ sudo mount -t iso9660 /dev/cdrw /cdrom mount: no medium found on /dev/sr1 Here are the contents of my /dev folder: austin@austinvpn:/proc/scsi$ ls /dev agpgart loop6 ram6 tty10 tty38 tty8 austinvpn loop7 ram7 tty11 tty39 tty9 block lp0 ram8 tty12 tty4 ttyS0 bsg mapper ram9 tty13 tty40 ttyS1 btrfs-control mcelog random tty14 tty41 ttyS2 bus mem rfkill tty15 tty42 ttyS3 cdrom net root tty16 tty43 urandom cdrom1 network_latency rtc tty17 tty44 usbmon0 cdrw network_throughput rtc0 tty18 tty45 usbmon1 char null scd0 tty19 tty46 usbmon2 console oldmem scd1 tty2 tty47 usbmon3 core parport0 sda tty20 tty48 usbmon4 cpu_dma_latency pktcdvd sda1 tty21 tty49 vcs disk port sda2 tty22 tty5 vcs1 dri ppp sda5 tty23 tty50 vcs2 ecryptfs psaux sg0 tty24 tty51 vcs3 fb0 ptmx sg1 tty25 tty52 vcs4 fd pts sg2 tty26 tty53 vcs5 full ram0 shm tty27 tty54 vcs6 fuse ram1 snapshot tty28 tty55 vcs7 hpet ram10 snd tty29 tty56 vcsa input ram11 sndstat tty3 tty57 vcsa1 kmsg ram12 sr0 tty30 tty58 vcsa2 log ram13 sr1 tty31 tty59 vcsa3 loop0 ram14 stderr tty32 tty6 vcsa4 loop1 ram15 stdin tty33 tty60 vcsa5 loop2 ram2 stdout tty34 tty61 vcsa6 loop3 ram3 tty tty35 tty62 vcsa7 loop4 ram4 tty0 tty36 tty63 vga_arbiter loop5 ram5 tty1 tty37 tty7 zero And here is my fstab file: austin@austinvpn:/proc/scsi$ cat /etc/fstab # /etc/fstab: static file system information. # # Use 'blkid -o value -s UUID' to print the universally unique identifier # for a device; this may be used with UUID= as a more robust way to name # devices that works even if disks are added and removed.

maintaining a growing, diverse codebase with continuous integration

- by Nate

I am in need of some help with philosophy and design of a continuous integration setup. Our current CI setup uses buildbot. When I started out designing it, I inherited (well, not strictly, as I was involved in its design a year earlier) a bespoke CI builder that was tailored to run the entire build at once, overnight. After a while, we decided that this was insufficient, and started exploring different CI frameworks, eventually choosing buildbot. One of my goals in transitioning to buildbot (besides getting to enjoy all the whiz-bang extras) was to overcome some of the inadequacies of our bespoke nightly builder. Humor me for a moment, and let me explain what I have inherited. The codebase for my company is almost 150 unique c++ Windows applications, each of which has dependencies on one or more of a dozen internal libraries (and many on 3rd party libraries as well). Some of these libraries are interdependent, and have depending applications that (while they have nothing to do with each other) have to be built with the same build of that library. Half of these applications and libraries are considered "legacy" and unportable, and must be built with several distinct configurations of the IBM compiler (for which I have written unique subclasses of Compile), and the other half are built with visual studio. The code for each compiler is stored in two separate Visual SourceSafe repositories (which I am simply handling using a bunch of ShellCommands, as there is no support for VSS). Our original nightly builder simply took down the source for everything, and built stuff in a certain order. There was no way to build only a single application, or pick a revision, or to group things. It would launched virtual machines to build a number of the applications. It wasn't very robust, it wasn't distributable. It wasn't terribly extensible. I wanted to be able to overcame all of these limitations in buildbot. The way I did this originally was to create entries for each of the applications we wanted to build (all 150ish of them), then create triggered schedulers that could build various applications as groups, and then subsume those groups under an overall nightly build scheduler. These could run on dedicated slaves (no more virtual machine chicanery), and if I wanted I could simply add new slaves. Now, if we want to do a full build out of schedule, it's one click, but we can also build just one application should we so desire. There are four weaknesses of this approach, however. One is our source tree's complex web of dependencies. In order to simplify config maintenace, all builders are generated from a large dictionary. The dependencies are retrieved and built in a not-terribly robust fashion (namely, keying off of certain things in my build-target dictionary). The second is that each build has between 15 and 21 build steps, which is hard to browse and look at in the web interface, and since there are around 150 columns, takes forever to load (think from 30 seconds to multiple minutes). Thirdly, we no longer have autodiscovery of build targets (although, as much as one of my coworkers harps on me about this, I don't see what it got us in the first place). Finally, aformentioned coworker likes to constantly bring up the fact that we can no longer perform a full build on our local machine (though I never saw what that got us, either, considering that it took three times as long as the distributed build; I think he is just paranoically phobic of ever breaking the build). Now, moving to new development, we are starting to use g++ and subversion (not porting the old repository, mind you - just for the new stuff). Also, we are starting to do more unit testing ("more" might give the wrong picture... it's more like any), and integration testing (using python). I'm having a hard time figuring out how to fit these into my existing configuration. So, where have I gone wrong philosophically here? How can I best proceed forward (with buildbot - it's the only piece of the puzzle I have license to work on) so that my configuration is actually maintainable? How do I address some of my design's weaknesses? What really works in terms of CI strategies for large, (possibly over-)complex codebases?

Creating a Synchronous BPEL composite using File Adapter

- by [email protected]

By default, the JDeveloper wizard generates asynchronous WSDLs when you use technology adapters. Typically, a user follows these steps when creating an adapter scenario in 11g: 1) Create a SOA Application with either "Composite with BPEL" or an "Empty Composite". Furthermore, if the user chooses "Empty Composite", then he or she is required to drop the "BPEL Process" from the "Service Components" pane onto the SOA Composite Editor. Either way, the user comes to the screen below where he/she fills in the process details. Please note that the user is required to choose "Define Service Later" as the template. 2) Creates the inbound service and outbound references and wires them with the BPEL component: 3) And, finally creates the BPEL process with the initiating <receive> activity to retrieve the payload and an <invoke> activity to write the payload. This is how most BPEL processes that use Adapters are modeled. And, if we scrutinize the generated WSDL, we can clearly see that the generated WSDL is one way and that makes the BPEL process asynchronous (see below) In other words, the inbound FileAdapter would poll for files in the directory and for every file that it finds there, it would translate the content into XML and publish to BPEL. But, since the BPEL process is asynchronous, the adapter would return immediately after the publish and perform the required post processing e.g. deletion/archival and so on. The disadvantage with such asynchronous BPEL processes is that it becomes difficult to throttle the inbound adapter. In otherwords, the inbound adapter would keep sending messages to BPEL without waiting for the downstream business processes to complete. This might lead to several issues including higher memory usage, CPU usage and so on. In order to alleviate these problems, we will manually tweak the WSDL and BPEL artifacts into synchronous processes. Once we have synchronous BPEL processes, the inbound adapter would automatically throttle itself since the adapter would be forced to wait for the downstream process to complete with a <reply> before processing the next file or message and so on. Please see the tweaked WSDL below and please note that we have converted the one-way to a two-way WSDL and thereby making the WSDL synchronous: Add a <reply> activity to the inbound adapter partnerlink at the end of your BPEL process e.g. Finally, your process will look like this: You are done. Please remember that such an excercise is NOT required for Mediator since the Mediator routing rules are sequential by default. In other words, the Mediator uses the caller thread (inbound file adapter thread) for processing the routing rules. This is the case even if the WSDL for mediator is one-way.

How to create (via installer script) a task that will install my bash script so it runs on DE startup?

- by MountainX

I've been reading for the last couple hours about Upstart, .xinitrc, .xsessions, rc.local, /etc/init.d/, /etc/xdg/autostart, @reboot in crontab and so many other things that I'm totally confused! Here is my bash script. It should start/run after the desktop environment is started and it should continue to run at all times until logout/shutdown. It should start again on reboot. Any time the DE is running, it should run. #!/bin/bash while true; do if [[ -s ~/.updateNotification.txt ]]; then read MSG < ~/.updateNotification.txt kdialog --title 'The software has been updated' --msgbox "$MSG" cat /dev/null > ~/.updateNotification.txt fi sleep 3600 done exit 0 I know zero about using Upstart, but I understand that Upstart is one way to handle this. I'll consider other approaches but most of the things I've been reading about are too complex for me. Furthermore, I can't figure out which approach will meet my requirements (which I'll detail below). There are two steps in my question: How to automatically start the script above, as described above. How to "install" that Upstart task via a bash script (i.e., my "installer"). I assume (or hope) that step 2 is almost trivial once I understand step 1. I have to support all flavors of Ubuntu desktops. Therefore, the kdialog call above will be replaced. I'm considering easybashgui for this. (Or I could use zenity on gnome DE's.) My requirements are: The setup process (installation) must be done via a bash script. I cannot use the GUI method described in the Ubuntu doc AddingProgramToSessionStartup, for example. I must be able to script/automate the setup (installing) process using bash. Currently, it is as simple as having the bash installer script copy the above script into /home/$USER/.kde/Autostart/ The setup process must be universal across Ubuntu derivatives including Unity and KDE and gnome desktops. The same setup script (installer) should run on Linux Mint, Kubuntu, Xbuntu (basically any flavor of Ubuntu and major derivatives such as Linux Mint). For example, we cannot continue to put a script file in /home/$USER/.kde/Autostart/ because that exists only on KDE. The above script should work for each of the limited flavors we use. Hence our interest in using easybashgui instead of kdialog or zenity. See below. The installed monitoring script should only be started after the desktop is started since it will display a GUI message to the user if the update is found. The monitoring script (above) should run without root privileges, of course. But the installer (bash script) can be run as root. I'm not a real developer or a sysadmin. This is a part time volunteer thing for me, so it needs to be easy/simple. I can write bash scripts and I can program a little, but I know nothing about Upstart or systemd, for example. And, unfortunately, my job doesn't give me time to become an expert on init systems or much of anything else related to development and sysadmin. So I have to stick with simple solutions. The easybashgui version of the script might look like this: #!/bin/bash source easybashgui while true; do if [[ -s ~/.updateNotification.txt ]]; then read MSG < ~/.updateNotification.txt message "$MSG" cat /dev/null > ~/.updateNotification.txt fi sleep 3600 done exit 0

ATG Live Webcast June 28: Scrambling Sensitive Data in EBS 12 Cloned Environments

- by BillSawyer

Securing the Oracle E-Business Suite includes protecting the underlying E-Business data in production and non-production databases. While steps can be taken to provide a secure configuration to limit EBS access, a better approach to protecting non-production data is simply to scramble (mask) the data in the non-production copy. The Oracle E-Business Suite Template for Data Masking Pack can be used in situations where confidential or regulated data needs to be shared with other non-production users who need access to some of the original data, but not necessarily every table. Examples of non-production users include internal application developers or external business partners such as offshore testing companies, suppliers or customers. The Oracle E-Business Suite Template for Data Masking Pack is applied to a non-production environment with the Enterprise Manager Grid Control Data Masking Pack. When applied, the Oracle E-Business Suite Template for Data Masking Pack will create an irreversibly scrambled version of your production database for development and testing. This ATG Live Webcast is your chance to come learn about the Oracle E-Business Suite Release 12.1.3 Template for Data Masking Pack from the experts. Oracle E-Business Suite Release 12.1.3 Template for Data Masking The agenda for the Oracle E-Business Suite Template for Data Masking Pack webcast includes the following topics: What does data masking do in E-Business Suite environments? De-identify the data Mask sensitive data Maintain data validity How can EBS customers use data masking?

Data Connection Library in SharePoint Server 2010

- by Wayne

What is a Data Connection Library in SharePoint Server 2010? A Data Connection Library in Microsoft SharePoint Server 2010 is a library that can contain two kinds of data connections: an Office Data Connection (ODC) file or a Universal Data Connection (UDC) file. Microsoft InfoPath 2010 uses data connections that comply with the Universal Data Connection (UDC) file schema and typically have either a *.udcx or *.xml file name extension. Data sources described by these data connections are stored on the server and can be used in standard form templates and browser-enabled form templates. How to create a SharePoint Server Data Connection Library? 1. Browse to a SharePoint Server 2010 site on which you have at least Design permissions. If you are on the root site, create a new site before you continue with the next step. 2. On the Site Actions menu, click More Options. 3. On the Create page, click Library under Filter By, and then click Data Connection Library. 4. On the right side of the Create page, type a name for the library, and then click the Create button. 5. Copy the URL of the new data connection library. How to create a new data connection file in InfoPath? 1. Open InfoPath Designer 2010, click Blank Form, and then click Design Form. 2. On the Data tab, click Data Connections, and then click Add. 3. In the Data Connection Wizard, click Create a new connection to, click Receive data, and then click Next. 4. Click the kind of data source that you are connecting to, such as Database, Web service, or SharePoint library or list, and then click Next. 5. Complete the remaining steps in the Data Connection Wizard to configure your data connection, and then click Finish to return to the Data Connections dialog box. 6. In the Data Connections dialog box, click Convert to Connection File. 7. In the Convert Data Connection dialog box, enter the URL of the data connection library that you previously copied (delete "Forms/AllItems.aspx" and anything following it from the URL), enter a name for the data connection file at the end of the URL, and then click OK. It will take a few moments to convert and save the data connection file to the library. 8. Confirm that the data connection was converted successfully by examining the Details section of the Data Connections dialog box while the name of the converted data connection is selected. 9. Browse to the SharePoint data connection library, click the drop-down next to the name of the data connection, click Approve/Reject, click Approved, and then click OK. Take advantage of SharePoint Data Connection Library and other useful features of SharePoint family of products that include, SharePoint Foundation 2010, MOSS 2007 and free SharePoint templates or web parts.

LINQ to Twitter Queries with LINQPad

- by Joe Mayo

LINQPad is a popular utility for .NET developers who use LINQ a lot. In addition to standard SQL queries, LINQPad also supports other types of LINQ providers, including LINQ to Twitter. The following sections explain how to set up LINQPad for making queries with LINQ to Twitter. LINQPad comes in a couple versions and this example uses LINQPad4, which runs on the .NET Framework 4.0. 1. The first thing you'll need to do is set up a reference to the LinqToTwitter.dll. From the Query menu, select query properties. Click the Browse button and find the LinqToTwitter.dll binary. You should see something similar to the Query Properties window below. 2. While you have the query properties window open, add the namespace for the LINQ to Twitter types. Click the Additional Namespace Imports tab and type in LinqToTwitter. The results are shown below: 3. The default query type, when you first start LINQPad, is C# Expression, but you'll need to change this to support multiple statements. Change the Language dropdown, on the Main window, to C# Statements. 4. To query LINQ to Twitter, instantiate a TwitterContext, by typing the following into the LINQPad Query window: var ctx = new TwitterContext(); Note: If you're getting syntax errors, go back and make sure you did steps #2 and #3 properly. 5. Next, add a query, but don't materialize it, like this: var tweets = from tweet in ctx.Status where tweet.Type == StatusType.Public select new { tweet.Text, tweet.Geo, tweet.User }; 6. Next, you want the output to be displayed in the LINQPad grid, so do a Dump, like this: tweets.Dump(); The following image shows the final results: That was an unauthenticated query, but you can also perform authenticated queries with LINQ to Twitter's support of OAuth. Here's an example that uses the PinAuthorizer (type this into the LINQPad Query window): var auth = new PinAuthorizer { Credentials = new InMemoryCredentials { ConsumerKey = "", ConsumerSecret = "" }, UseCompression = true, GoToTwitterAuthorization = pageLink => Process.Start(pageLink), GetPin = () => { // this executes after user authorizes, which begins with the call to auth.Authorize() below. Console.WriteLine("\nAfter you authorize this application, Twitter will give you a 7-digit PIN Number.\n"); Console.Write("Enter the PIN number here: "); return Console.ReadLine(); } }; // start the authorization process (launches Twitter authorization page). auth.Authorize(); var ctx = new TwitterContext(auth, "https://api.twitter.com/1/", "https://search.twitter.com/"); var tweets = from tweet in ctx.Status where tweet.Type == StatusType.Public select new { tweet.Text, tweet.Geo, tweet.User }; tweets.Dump(); This code is very similar to what you'll find in the LINQ to Twitter downloadable source code solution, in the LinqToTwitterDemo project. For obvious reasons, I changed the value assigned to ConsumerKey and ConsumerSecret, which you'll have to obtain by visiting http://dev.twitter.com and registering your application. One tip, you'll probably want to make this easier on yourself by creating your own DLL that encapsulates all of the OAuth logic and then call a method or property on you custom class that returns a fully functioning TwitterContext. This will help avoid adding all this code every time you want to make a query. Now, you know how to set up LINQPad for LINQ to Twitter, perform unauthenticated queries, and perform queries with OAuth. Joe

SQL SERVER – What are Actions in SSAS and How to Make a Reporting Action

- by Pinal Dave

Actions are used for customized browsing and drilling of data for the end-user. It’s an event that a user can raise while accessing the cube data. They are used in cube browsers like excel and are triggered when a user in a client tool clicks on a particular member, level, dimension, cells or may be the cube itself. For example a user might be able to see a reporting services report, open a web page or drill through to detailed information related to the cube data. Analysis server supports 3 types of actions :- Report Drill-through Standard Actions In this blog post, I will explain the Reporting action. The objective of this action is to return a report with details of the product where the sales amount is greater than 1000 in cube browser analysis. You need to create a basic cube first with the facts and dimensions you want in the analysis. Following are the steps to create reporting action. Go to SQL server data tools and open the analysis services project. Navigate to actions and click on new reporting action. 2.) Specify the name of the action and choose target type as attribute members since we have to create the action on members for a attribute. 3.) Specify the Target object of your report action. Target object would be the dimension or attribute on which you want the report to appear. In our case it is product name. 4.) Next you have to define the condition on which you want the report link to appear. However, this is an optional feature. In this example we are specifying a condition, which will check if the sales amount is greater than 10,000. So, that the link appears only for those products where the defined condition is met. 5.) Next you have to specify the server name on which the report is present, report path and the report format in which you want the report to appear. 6.) Additionally you can specify the parameters. As with conditional expression, the parameters should be a valid MDX expression. The parameter name should be same as the one defined in the report. 7.) Deploy your solution after you are done with specifying parameters and go to the cube browser. 8.) Click on the analyze in excel button, this will open your cube in excel 9.) Make an analysis which shows product names and their sales amount. 10.) Right click on a product where sales amount is greater than 10000 you will see the reporting action link. Click on that and you will be taken to your reporting services report. 11.) Clicking on the link will take you to the URL of the report. I created this report using report project wizard in SQL server data tools. So, this is how we can launch reports from a cube browser. Similarly you can open web pages, run applications and a number of other tasks. Koenig Solutions offers SSAS training which contains all Analysis Services including Reporting in great detail.

Monitor SQL Server Replication Jobs

- by Yaniv Etrogi

The Replication infrastructure in SQL Server is implemented using SQL Server Agent to execute the various components involved in the form of a job (e.g. LogReader agent job, Distribution agent job, Merge agent job) SQL Server jobs execute a binary executable file which is basically C++ code. You can download all the scripts for this article here SQL Server Job Schedules By default each of job has only one schedule that is set to Start automatically when SQL Server Agent starts. This schedule ensures that when ever the SQL Server Agent service is started all the replication components are also put into action. This is OK and makes sense but there is one problem with this default configuration that needs improvement - if for any reason one of the components fails it remains down in a stopped state. Unless you monitor the status of each component you will typically get to know about such a failure from a customer complaint as a result of missing data or data that is not up to date at the subscriber level. Furthermore, having any of these components in a stopped state can lead to more severe problems if not corrected within a short time. The action required to improve on this default settings is in fact very simple. Adding a second schedule that is set as a Daily Reoccurring schedule which runs every 1 minute does the trick. SQL Server Agent’s scheduler module knows how to handle overlapping schedules so if the job is already being executed by another schedule it will not get executed again at the same time. So, in the event of a failure the failed job remains down for at most 60 seconds. Many DBAs are not aware of this capability and so search for more complex solutions such as having an additional dedicated job running an external code in VBS or another scripting language that detects replication jobs in a stopped state and starts them but there is no need to seek such external solutions when what is needed can be accomplished by T-SQL code. SQL Server Jobs Status In addition to the 1 minute schedule we also want to ensure that key components in the replication are enabled so I can search for those components by their Category, and set their status to enabled in case they are disabled, by executing the stored procedure MonitorEnableReplicationAgents. The jobs that I typically have handled are listed below but you may want to extend this, so below is the query to return all jobs along with their category. SELECT category_id, name FROM msdb.dbo.syscategories ORDER BY category_id; Distribution Cleanup LogReader Agent Distribution Agent Snapshot Agent Jobs By default when a publication is created, a snapshot agent job also gets created with a daily schedule. I see more organizations where the snapshot agent job does not need to be executed automatically by the SQL Server Agent scheduler than organizations who need a new snapshot generated automatically. To assure this setting is in place I created the stored procedure MonitorSnapshotAgentsSchedules which disables snapshot agent jobs and also deletes the job schedule. It is worth mentioning that when the publication property immediate_sync is turned off then the snapshot files are not created when the Snapshot agent is executed by the job. You control this property when the publication is created with a parameter called @immediate_sync passed to sp_addpublication and for an existing publication you can use sp_changepublication. Implementation The scripts assume the existence of a database named PerfDB. Steps: Run the scripts to create the stored procedures in the PerfDB database. Create a job that executes the stored procedures every hour. -- Verify that the 1_Minute schedule exists. EXEC PerfDB.dbo.MonitorReplicationAgentsSchedules @CategoryId = 10; /* Distribution */ EXEC PerfDB.dbo.MonitorReplicationAgentsSchedules @CategoryId = 13; /* LogReader */ -- Verify all replication agents are enabled. EXEC PerfDB.dbo.MonitorEnableReplicationAgents @CategoryId = 10; /* Distribution */ EXEC PerfDB.dbo.MonitorEnableReplicationAgents @CategoryId = 13; /* LogReader */ EXEC PerfDB.dbo.MonitorEnableReplicationAgents @CategoryId = 11; /* Distribution clean up */ -- Verify that Snapshot agents are disabled and have no schedule EXEC PerfDB.dbo.MonitorSnapshotAgentsSchedules; Want to read more of about replication?

Where's My Windows Azure Subscriptions

- by Shaun

Originally posted on: http://geekswithblogs.net/shaunxu/archive/2013/11/03/wheres-my-windows-azure-subscriptions.aspxYesterday when I opened Windows Azure manage portal I found some resources were missed. I checked the website for those missed cloud service and they are still live. Then I checked my billing history but didn't found any problem. When I back to the portal I found that all of those resource are under my MSDN subscription. So I remembered that if this is related with the recently Windows Azure platform update. This feature named "Enterprise Management", which provides the ability to manage your organization in a directory which is hosted entirely in the cloud, or alternatively kept in sync with an on-premises Windows Server Active Directory solution. By default, all existing windows azure account would have a default Windows Azure Active Directory (a.k.a. WAAD) associated. In the address bar I can find the default login WAAD of my account, which is "microsoft.onmicrosoft.com". To change the WAAD we can click "subscriptions" on top of the manage portal, select the active directory from the list of "filter by directory" and select the subscription we want to see, then press "apply". As you can see, the subscription under my MSDN was located in a WAAD named "beijingtelecom.onmicrosoft.com". This is because when Microsoft applied this feature, they will check if you have an existing WAAD in your subscription. If not, it will create a new one, otherwise it will use your WAAD and move your subscription into this directory. Since I created a WAAD for test several months ago, this subscription was moved to this directory. To change the subscription's directory is simple. First we need to create a new WAAD with the name we preferred. As below I created a new directory named "shaunxu". Then select "settings" from the left navigation bar, select the subscription we wanted to change and click "edit directory". You don't have the permission to edit/change directory unless your Microsoft Account is the service administrator of this subscription. Then in the popup window, select the WAAD you want to change and press "next". All done. You need to log off and log in the portal then your subscription will be in the directory you wanted. And after these steps I can view my resources in this subscription. Summary In this post I described how to change subscriptions into a new directory. With this new feature we can manage our Windows Azure subscription more flexible. But there are something we need keep in mind. 1. Only the service administrator could be able to move subscription. 2. Currently there's no way for us to see our Windows Azure services in more than one directory at the same time. Like me, I can see my services under "shaunxu.onmicrosoft.com" and I must change the filter directory from the "subscriptions" menu to see other services under "microsoft.onmicrosoft.com". 3. Currently we cannot delete an existing WAAD. Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind. Copyright © Shaun Ziyan Xu.

Upgrading from MVC 1.0 to MVC2 in Visual Studio 2010 and VS2008.

- by Sam Abraham

With MVC2 officially released, I was involved in a few conversations regarding the feasibility of upgrading existing MVC 1.0 projects to quickly leverage the newly introduced MVC features. Luckily, Microsoft has proactively addressed this question for both Visual Studio 2008 and 2010 and many online resources discussing the upgrade process are a "Bing/Google Search" away. As I will happen to be speaking about MVC2 and Visual Studio 2010 at the Ft Lauderdale ArcSig .Net User Group Meeting on April 20th 2010 (Check http://www.fladotnet.com for more info.), I decided to include a quick demo on upgrading the NerdDinner project (which I consider the "Hello MVC World" project) from MVC 1.0 to MVC2 using Visual studio 2010 to demonstrate how simple the upgrade process is. In the next few lines, I will be briefly touching on upgrading to MVC2 for Visual Studio 2008 then discussing, in more detail, the upgrade process using Visual Studio 2010 while highlighting the advantage of its multi-targeting support. Using Visual Studio 2008 SP1 For upgrading to MVC2 Using VS2008 SP1, a Microsoft White Paper [1] presents two approaches: 1- Using a provided automated upgrade tool, 2-Manually upgrading the project. I personally prefer using the automated tool although it comes with an "AS IS" disclaimer. For those brave souls, or those who end up with no luck using the tool, detailed manual upgrade steps are also provided as a second option. Backing up the project in question is a must regardless of which route one would take to upgrade. Using Visual Studio 2010 Life is much easier for developers who already adopted Visual Studio 2010. Simply opening the MVC 1.0 solution file brings up the upgrade wizard as shown in figures 1, 2, 3 and 4. As we proceed with the upgrade process, the wizard requests confirmation on whether we choose to upgrade our target framework version to .Net 4.0 or keep the existing .Net 3.5 (Figure 5). VS2010 does a good job with multi-targeting where we can still develop .Net 3.5 applications while leveraging all the new bells and whistles that VS2010 brings to the table (Multi-targeting enables us to develop with as early as .Net 2.0 in VS2010) Figure 1 - Open Solution File Using VS2010 Figure 2 - VS2010 Conversion Wizard Figure 3- Ready To Convert To VS2010 Confirmation Screen Figure 4 - VS2010 Solution Conversion Progress Figure 5 - Confirm Target Framework Upgrade In an attempt to make my demonstration realistic, I decided to opt to keep the project targeted to the .Net 3.5 Framework. After the successful completion of the conversion process, a quick sanity check revealed that the NerdDinner project is still targeted to the .Net 3.5 framework as shown in figure 6. Inspecting the Web.Config revealed that the MVC DLL version our code compiles against has been successfully upgraded to 2.0 (Figure 7) and hence we should now be able to leverage the newly introduced features in MVC2 and VS2010 with no effort or time invested on modifying existing code. Figure 6- Confirm Target Framework Remained .Net 3.5 Figure 7 - Confirm MVC DLL Version Has Been Upgraded In Conclusion, Microsoft has empowered developers with the tools necessary to quickly and seamlessly upgrade their MVC solutions to the newly released MVC2. The multi-targeting feature in Visual Studio 2010 enables us to adopt this latest and greatest development tool while supporting development in as early as .Net 2.0. References 1.

How to Get Windows 7 Theme Wallpapers Without Installing Them

- by Mysticgeek

Are you using an older version of Windows but like the Windows 7 theme wallpapers? What if you have Windows 7 but you don’t want to install the themes just to get the wallpapers? Here is how to get them without having to install themes. This guest article was written by Ryan Dozier from the Doztech tech blog. Getting the Wallpaper on XP, Vista, or Windows 7 First download and install 7-zip on your machine (link below). After you’ve installed 7-zip, download a Windows 7 theme (link below) and right-click on the theme, select 7-Zip, and Extract to “Theme Name”… A new folder will appear with the theme name on it. When you open it, there will be a folder called DesktopBackground or something similar. Open the folder to get the wallpapers to view the wallpapers for the theme. You can delete the extra files and just keep the wallpapers! Getting the Wallpaper on Ubuntu Extracting the wallpaper on Ubuntu can be a little tricky. Just follow these steps and you will be able to do it. First go to the Ubuntu Software Center under the Applications menu. Search for 7zip and click on the arrow to go to the applications menu. Find the Install button and click it. It will take a couple of minutes for 7zip to install. After 7zip installs, close the Ubuntu Software Center and download a Windows 7 theme. Store it somewhere you can access it quickly. Right-click on the theme and select Rename and get rid of the themepack extension and replace it with zip. The file should be “Theme Name.zip” after you rename it. Right-click on the theme and click Extract Here. After the extracting you will have a new folder with the theme name. Open it and go into the DesktopBackground folder to get the wallpapers. You can delete the extra files and just keep the wallpapers. If you want to get the new Windows 7 Themes Wallpapers, but don’t want to search and install them separately, this is a nice workaround.

How to move complete SharePoint Server 2007 from one box to another

- by DipeshBhanani

It was time of my first onsite client assignment on SharePoint. Client had one server production environment. They wanted to upgrade the topology with completely new SharePoint Farm of three servers. So, the task was to move whole MOSS 2007 stuff to the new server environment without impacting data. The last three scary words “… without impacting data…” were actually putting pressure on my head. Moreover SSP was required to move because additional information has been added for users apart from AD import. I thought I had to do only backup and restore. It appeared pretty easy at first thought. Just because of these damn scary words, I thought to check out on internet for guidance related to this scenario. I couldn’t get anything except general guidance of moving server on Microsoft TechNet site. I promised myself for starting blogs with this post if I would be successful in this task. Well, I took long time to write this but finally made it. I hope it will be useful to all guys looking for SharePoint server movement. Before beginning restoration, make sure that, there is no difference in versions of SharePoint at source and destination server. Also check whether the state of SharePoint Installation at the time of backup and restore is same or not. (E.g. SharePoint related service packs and patches if any) The main tasks of the server movement are as follow: Backup all the databases Install and configure SharePoint on new environment Deploy all solution (WSP Files) globally to destination server- for installing features attached to the solutions Install all the custom features Deploy/Copy custom pages/files which are added to the “12Hive” folder later Restore SSP Restore My Site Restore other web application Tasks 3 to 5 are for making sure that we have configured the environment well enough for the web application to be restored successfully. The main and complex task was restoring SSP. I have started restoring SSP through Central Admin. After a while, the restoration status was updated to “unsuccessful”. “Damn it, what went wrong?” I thought looking at the error detail down the page. I couldn’t remember the error message but I had corrected and restored it again. Actually once you fail restoring SSP, until and unless you don’t clean all related stuff well, your restoration will be failed again and again. I wanted to find the actual reason. So cleaned, restored, cleaned, restored… I had tried almost 5-6 times and finally, I succeeded. I had realized how pleasant it is, to see the word “Successful” on the screen. Without wasting your much time to read, let me write all the detailed steps of restoring SSP: Delete the SSP through following STSADM command. stsadm -o deletessp -title <SSP name> -deletedatabases -force e.g.: stsadm -o deletessp -title SharedServices1 -deletedatabases –force Check and delete the web application associated with SSP if it exists. Remove Link from Check and remove “Alternate Access Mapping” associated with SSP if it exists. Check and delete IIS site as well as application pool associated with SSP if it exists. Stop following services: · Office SharePoint Server Search · Windows SharePoint Services Search · Windows SharePoint Services Help Search Delete all the databases associated/related to SSP from SQL Server. Reset IIS. Start again following services: · Office SharePoint Server Search · Windows SharePoint Services Search · Windows SharePoint Services Help Search Restore the new SSP. After the SSP restoration, all other stuffs had completed very smoothly without any more issues. I did few modifications to sites for change of server name and finally, the new environment was ready.

Attachments in Oracle BPM 11g – Create a BPM Process Instance by passing an Attachment

- by Venugopal Mangipudi

Problem Statement: On a recent engagement I had a requirement where we needed to create BPM instances using a message start event. The challenge was that the instance needed to be created after polling a file location and attaching the picked up file (pdf) as an attachment to the instance. Proposed Solution: I was contemplating using process API to accomplish this,but came up with a solution which involves a BPEL process to pickup the file and send a notification to the BPM process by passing the attachment as a payload. The following are some of the brief steps that were used to build the solution: BPM Process to receive an attachment as part of the payload: The BPM Process is a very simple process which has a Message Start event that accepts the attachment as an argument and a Simple User Task that the user can use to view the attachment (as part of the OOTB attachment panel). The Input payload is based on AttachmentPayload.xsd. The 3 key elements of the the payload are: <xsd:element name="filename" type="xsd:string"/> <xsd:element name="mimetype" type="xsd:string"/> <xsd:element name="content" type="xsd:base64Binary"/> A screenshot of the Human task data assignment that need to performed to attach the file is provided here. Once the process and the UI project (default generated UI) are deployed to the SOA server, copy the wsdl location of the process service (from EM). This WSDL would be used in the BPEL project to create the Instances in the BPM process after a file is polled. BPEL Process to Poll for File and create instances in the BPM process: For the BPEL process a File adapter was configured as a Read service (File Streaming option and keeping the Schema as Opaque). Once a location and the file pattern to poll are provided the Readservice Partner Link was wired to Invoke the BPEL Process. Also, using the BPM Process WSDL, we can create the Webservice reference and can invoke the start operation. Before we do the assignment for the Invoke operation, a global variable should be created to hold the value of the fileName of the file. The mapping to the global variable can be done on the Receive activity properties (jca.file.FileName). So for the assign operation before we invoke the BPM process service, we can get the content of the file from the receive input variable and the fileName from the jca.file.FileName property. The mimetype needs to be hard coded to the mime-type of the file: application/pdf (I am still researching ways to derive the mime type as it is not available as part of the jca.file properties). The screenshot of the BPEL process can be found here and the Assign activity can be found here. The project source can be found at the following location. A sample pdf file to test the project and a screenshot of the BPM Human task screen after the successful creation of the instance can be found here.

ORA-4031 Troubleshooting

- by [email protected]

QUICKLINK: Note 396940.1 Troubleshooting and Diagnosing ORA-4031 Error Note 1087773.1 : ORA-4031 Diagnostics Tools [Video] Have you observed an ORA-04031 error reported in your alert log? An ORA-4031 error is raised when memory is unavailable for use or reuse in the System Global Area (SGA). The error message will indicate the memory pool getting errors and high level information about what kind of allocation failed and how much memory was unavailable. The challenge with ORA-4031 analysis is that the error and associated trace is for a "victim" of the problem. The failing code ran into the memory limitation, but in almost all cases it was not part of the root problem. Looking for the best way to diagnose? When an ORA-4031 error occurs, a trace file is raised and noted in the alert log if the process experiencing the error is a background process. User processes may experience errors without reports in the alert log or traces generated. The V$SHARED_POOL_RESERVED view will show reports of misses for memory over the life of the database. Diagnostics scripts are available in Note 430473.1 to help in analysis of the problem. There is also a training video on using and interpreting the script data Note 1087773.1. 11g DiagnosabilityStarting with Oracle Database 11g Release 1, the Diagnosability infrastructure was introduced which places traces and core files into a location controlled by the DIAGNOSTIC_DEST initialization parameter when an incident, such as an ORA-4031 occurs. For earlier versions, the trace file will be written to either USER_DUMP_DEST (if the error was caught in a user process) or BACKGROUND_DUMP_DEST (if the error was caught in a background process like PMON or SMON). The trace file contains vital information about what led to the error condition. Note 443529.1 11g Quick Steps to Package and Send Critical Error Diagnostic Information to Support[Video]Oracle Configuration Manager (OCM)Oracle Configuration Manager (OCM) works with My Oracle Support to enable proactive support capability that helps you organize, collect and manage your Oracle configurations.Oracle Configuration Manager Quick Start GuideNote 548815.1: My Oracle Support Configuration Management FAQ Note 250434.1: BULLETIN: Learn More About My Oracle Support Configuration Manager Common Causes/Solutions The ORA-4031 can occur for many different reasons. Some possible causes are: SGA components too small for workload Auto-tuning issues Fragmentation due to application design Bug/leaks in memory allocationsFor more on the 4031 and how this affects the SGA, see Note 396940.1 Troubleshooting and Diagnosing ORA-4031 Error Because of the multiple potential causes, it is important to gather enough diagnostics so that an appropriate solution can be identified. However, most commonly the cause is associated with configuration tuning. Ensuring that MEMORY_TARGET or SGA_TARGET are large enough to accommodate workload can get around many scenarios. The default trace associated with the error provides very high level information about the memory problem and the "victim" that ran into the issue. The data in the default trace is not going to point to the root cause of the problem. When migrating from 9i to 10g and higher, it is necessary to increase the size of the Shared Pool due to changes in the basic design of the shared memory area. Note 270935.1 Shared pool sizing in 10gNOTE: Diagnostics on the errors should be investigated as close to the time of the error(s) as possible. If you must restart a database, it is not feasible to diagnose the problem until the database has matured and/or started seeing the problems again.

JDeveloper 11g R1 (11.1.1.4.0) - New Features on ADF Desktop Integration Explained

- by juan.ruiz

One of the areas that introduced many new features on the latest release (11.1.1.4.0) of JDeveloper 11g R1 is ADF Desktop integration - in this article I’ll provide an overview of these new features. New ADF Desktop Integration Ribbon in Excel - After installing the ADF desktop integration add-in and depending on the mode in which you open the desktop integration workbook, the ADF Desktop integration ribbon for design time and runtime are displayed as a separate tab within Excel. In previous version the ADF Desktop integration environment used to be placed inside the add-ins tab. Above you can see both, design time ribbon as well as runtime ribbon. On the design time ribbon you can manage the workbook and worksheet properties, worksheet component properties, diagnostics, execution and publication of the workbook. The runtime version of the ribbon is totally customizable and represents what it used to be the runtime menu on the spreadsheet, in this ribbon you can include all the operations and actions that could be executed by the end user while working with the spreadsheet data. Diagnostics - A very important aspect for developers is how to debug or verify the interactions of the client with the server, for that ADF desktop integration has provided since day one a series of diagnostics tools. In this release the diagnostics tools are more visible and are really easy to configure. You can access the client console while testing the workbook, or you can simple dump all the messages to a log file – having the ability of setting the output level for both. Security - There are a number of enhancements on security but the one with more impact for developers is tha security now is optional when using ADF Desktop Integration. Until this version every time that you wanted to work with ADFdi it was a must that the application was previously secured. In this release security is optional which means that if you have previously defined security on your application, then you must secure the ADFdi servlet as explained in one of my previous (ADD LINK) posts. In the other hand, if but the time that you start working with ADFdi you have not defined security, you can test and publish your workbooks without adding security. Support for Continuous Integration - In this release we have added tooling for continuous integration building. in the ADF desktop integration space, the concept translates to adding functionality that developers can use to publish ADFdi workbooks as part of their entire application build. For that purpose, we have a publish tool that can be easily invoke from an ANT task such that all the design time workbooks are re-published into the latest version of the application building process. Key Column - At runtime, on any worksheet containing editable tables you will notice a new additional column called the key column. The purpose of this column is to make the end user aware that all rows on the table need to be selected at the time of sorting. The users cannot alter the value of this column. From the developers points of view there are no steps required in order to have the key column included into the worksheets. Installation and Creation of New Workbooks - Both use cases can be executed now directly from JDeveloper. As part of the Tools menu options the developer can install the ADF desktop integration designer. Also, creating new workbooks that previously was done through that convert tool shipped with JDeveloper is now automatic done from the New Gallery. Creating a new ADFdi workbook adds metadata information information to the Excel workbook so you can work in design time. Other Enhancements Support for Excel 2010 and the ADF components ready-only enabled don’t allow to change its value – the cell in Excel is automatically protected, this could cause confusion among customers of previous releases.

So I installed npm and node with these commands. sudo apt-get install npm sudo apt-get install node and I tried to install autosave here is the output: sudo npm install -g autosave npm http GET https://registry.npmjs.org/autosave npm http 304 https://registry.npmjs.org/autosave npm http GET https://registry.npmjs.org/commander npm http 304 https://registry.npmjs.org/commander /usr/local/bin/autosave -> /usr/local/lib/node_modules/autosave/bin/autosave > [email protected] install /usr/local/lib/node_modules/autosave > node ./scripts/install.js npm ERR! error installing [email protected] npm WARN This failure might be due to the use of legacy binary "node" npm WARN For further explanations, please read npm WARN /usr/share/doc/nodejs/README.Debian npm WARN npm ERR!

Node does not look for modules in /usr/local/lib/node_modules, where npm put them. Please read npm-link(1) of npm package, to understand how to properly use npm-installed modules in a project. Note that require.paths is not supported in future node versions. See also node(1) for more information about NODE_PATH. nodejs command -------------- The upstream name for the Node.js interpreter command is "node". In Debian the interpreter command has been changed to "nodejs". This was done to prevent a namespace collision: other commands use the same name in their upstreams, such as ax25-node from the "node" package. Scripts calling Node.js as a shell command must be changed to instead use the "nodejs" command.

Free RAM disappears - Memory leak?

- by Izzy

On a fresh started system, free reports about 1.5G used RAM (8G RAM alltogether, Ubuntu 12.04 with lightdm and plasma desktop, one konsole window started). Having the apps running I use, it still consumes not more than 2G. However, having the system running for a couple of days, more and more of my free RAM disappears -- without showing up in the list of used apps: while smem --pie=name reports less than 20% used (and 80% being available), everything else says differently. free -m for example reports on about day 7: total used free shared buffers cached Mem: 7459 7013 446 0 178 997 -/+ buffers/cache: 5836 1623 Swap: 9536 296 9240 (so you can see, it's not the buffers or the cache). Today this finally ended with the system crashing completely: the windows manager being gone, apps "hanging in the air" (frameless) -- and a popup notifying me about "too many open files". Syslog reports: kernel: [856738.020829] VFS: file-max limit 752838 reached So I closed those applications I was able to close, and killed X using Ctrl-Alt-backspace. X tried to come up again after that with failsafeX, but was unable to do so as it could no longer detect its configuration. So I switched to a console using Ctrl-Alt-F2, captured all information I could think of (vmstat, free, smem, proc/meminfo, lsof, ps aux), and finally rebooted. X again came up with failsafeX; this time I told it to "recover from my backed-up configuration", then switched to a console and successfully used startx to bring up the graphical environment. I have no real clue to what is causing this issue -- though it must have to do either with X itself, or with some user processes running on X -- as after killing X, free -m output looked like this: total used free shared buffers cached Mem: 7459 2677 4781 0 62 419 -/+ buffers/cache: 2195 5263 Swap: 9536 59 9477 (~3.5GB being freed) -- to compare with the output after a fresh start: total used free shared buffers cached Mem: 7459 1483 5975 0 63 730 -/+ buffers/cache: 689 6769 Swap: 9536 0 9536 Two more helpful outputs are provided by memstat -u. Shortly before the crash: User Count Swap USS PSS RSS mail 1 0 200 207 616 whoopsie 1 764 740 817 2300 colord 1 3200 836 894 2156 root 62 70404 352996 382260 569920 izzy 80 177508 1465416 1519266 1851840 After having X killed: User Count Swap USS PSS RSS mail 1 0 184 188 356 izzy 1 1400 708 739 1080 whoopsie 1 848 668 826 1772 colord 1 3204 804 888 1728 root 62 54876 131708 149950 267860 And after a restart, back in X: User Count Swap USS PSS RSS mail 1 0 212 217 628 whoopsie 1 0 1536 1880 5096 colord 1 0 3740 4217 7936 root 54 0 148668 180911 345132 izzy 47 0 370928 437562 915056 Edit: Just added two graphs from my monitoring system. Interesting to see: everytime when there's a "jump" in memory consumption, CPU peaks as well. Just found this right now -- and it reminds me of another indicator pointing to X itself: Often when returning to my machine and unlocking the screen, I found something doing heavvy work on my CPU. Checking with top, it always turned out to be /usr/bin/X :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch -background none. So after this long explanation, finally my questions: What could be the possible causes? How can I better identify involved processes/applications? What steps could be taken to avoid this behaviour -- short from rebooting the machine all X days? I was running 8.04 (Hardy) for about 5 years on my old machine, never having experienced the like (always more than 100 days uptime, before rebooting for e.g. kernel updates). This now is a complete new machine with a fresh install of 8.04. In case it matters, some specs: AMD A4-3400 APU with Radeon(tm) HD Graphics, using the open-source ati/radeon driver (so no fglrx installed), 8GB RAM, WDC WD1002FAEX-0 hdd (1TB), Asus F1A75-V Evo mainboard. Ubuntu 12.04 64-bit with KDE4/Plasma. Apps usually open more or less permanently include Evolution, Firefox, konsole (with Midnight Commander running inside, about 4 tabs), and LibreOffice -- plus occasionally Calibre, Gimp and Moneyplex (banking software I'm already using for almost 20 years now, in a version which did fine on Hardy).

Creating a new naming context in OUD

- by Sylvain Duloutre

A naming context (also known as a directory suffix) is a DN that identifies the top entry in a locally held directory hierarchy. A new naming context can be created using ODSM, the OUD gui admin console, as described in http://docs.oracle.com/cd/E29407_01/admin.111200/e22648/server_config.htm#CBDGCJGF It can also be created using the dsconfig command lione as described below: Creation of a new naming context consists in 3 steps: First create a Local Backend Workflow element (myNewDb in this exemple) , responsible for the naming context base dn, e.g o=example. dsconfig create-workflow-element \ --set base-dn:o=example \ --set enabled:true \ --type db-local-backend \ --element-name myNewDb \ --hostname <your host> \ --port <admin port> \ --bindDN cn=Directory\ Manager \ --bindPasswordFile ****** \ --no-prompt Second, create a Workflow element (workFlowForMyNewDb in this exemple) associated with the Local Backend Workflow element. WorkFlow elements are used to route LDAP requests to the appropriate database, based on the target base dn. dsconfig create-workflow \ --set base-dn:o=example \ --set enabled:true \ --set workflow-element:myNewDb \ --type generic \ --workflow-name workFlowForMyNewDb \ --hostname <your host name> \ --port <admin port>\ --bindDN cn=Directory\ Manager \ --bindPasswordFile ****** \ --no-prompt Then, the workflow element must be made visible outside of the directory, i.e added to the internal "routing table". This is done by adding the Workflow to the appropriate Network Group. A Network group is used to classify incoming client connections and route requests to workflows. dsconfig set-network-group-prop \ --group-name network-group \ --add workflow:workFlowForMyNewDb \ --hostname <your hostname> \ --port <admin port>\ --bindDN cn=Directory\ Manager \ --bindPasswordFile ****** \ --no-prompt At that stage, it is possible to import entries to the new naming context o=example.

Handling null values and missing object properties in Silverlight 4

- by PeterTweed

Before Silverlight 4 to bind a data object to the UI and display a message associated with either a null value or if the binding path was wrong, you would need to write a Converter. In Silverlight 4 we find the addition of the markup extensions TargetNullValue and FallbackValue that allows us to display a value when a null value is found in the bound to property and display a value when the property being bound to is not found. This post will show you how to use both markup extensions. Steps: 1. Create a new Silverlight 4 application 2. In the body of the MainPage.xaml.cs file replace the MainPage class with the following code: public partial class MainPage : UserControl { public MainPage() { InitializeComponent(); this.Loaded += new RoutedEventHandler(MainPage_Loaded); } void MainPage_Loaded(object sender, RoutedEventArgs e) { person p = new person() { NameValue = "Peter Tweed" }; this.DataContext = p; } } public class person { public string NameValue { get; set; } public string TitleValue { get; set; } } This code defines a class called person with two properties. A new instance of the class is created, only defining the value for one of the properties and bound to the DataContext of the page. 3. In the MainPage.xaml file copy the following XAML into the LayoutRoot grid: <Grid.RowDefinitions> <RowDefinition Height="60*" /> <RowDefinition Height="28*" /> <RowDefinition Height="28*" /> <RowDefinition Height="30*" /> <RowDefinition Height="154*" /> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="86*" /> <ColumnDefinition Width="314*" /> </Grid.ColumnDefinitions> <TextBlock Grid.Row="1" Height="23" HorizontalAlignment="Left" Margin="32,0,0,0" Name="textBlock1" Text="Name Value:" VerticalAlignment="Top" /> <TextBlock Grid.Row="2" Height="23" HorizontalAlignment="Left" Margin="32,0,0,0" Name="textBlock2" Text="Title Value:" VerticalAlignment="Top" /> <TextBlock Grid.Row="3" Height="23" HorizontalAlignment="Left" Margin="32,0,0,0" Name="textBlock3" Text="Non Existant Value:" VerticalAlignment="Top" /> <TextBlock Grid.Column="1" Grid.Row="1" Height="23" HorizontalAlignment="Left" Name="textBlock4" Text="{Binding NameValue, TargetNullValue='No Name!!!!!!!'}" VerticalAlignment="Top" Margin="6,0,0,0" /> <TextBlock Grid.Column="1" Grid.Row="2" Height="23" HorizontalAlignment="Left" Name="textBlock5" Text="{Binding TitleValue, TargetNullValue='No Title!!!!!!!'}" VerticalAlignment="Top" Margin="6,0,0,0" /> <TextBlock Grid.Column="1" Grid.Row="3" Height="23" HorizontalAlignment="Left" Margin="6,0,0,0" Name="textBlock6" Text="{Binding AgeValue, FallbackValue='No such property!'}" VerticalAlignment="Top" /> This XAML defines three textblocks – two of which use the TargetNull and one that uses the FallbackValue markup extensions. 4. Run the application and see the person name displayed as defined for the person object, the expected string displayed for the TargetNullValue when no value exists for the boudn property and the expected string displayed for the FallbackValue when the property bound to is not found on the bound object. It's that easy!
