  • Attach to Process in Visual Studio

    - by Daniel Moth
    One option for achieving step 1 in the Live Debugging process is attaching to an already running instance of the process that hosts your code, and this is a good place for me to talk about debug engines. You can attach to a process by selecting the "Debug" menu and then the "Attach To Process…" menu in Visual Studio 11 (Ctrl+Alt+P with my keyboard bindings), and you should see something like this screenshot: I am not going to explain this UI, besides being fairly intuitive, there is good documentation on MSDN for the Attach dialog. I do want to focus on the row of controls that starts with the "Attach to:" label and ends with the "Select..." button. Between them is the readonly textbox that indicates the debug engine that will be used for the selected process if you click the "Attach" button. If you haven't encountered that term before, read on MSDN about debug engines. Notice that the "Type" column shows the Code Type(s) that can be detected for the process. Typically each debug engine knows how to debug a specific code type (the two terms tend to be used interchangeably). If you click on a different process in the list with a different code type, the debug engine used will be different. However note that this is the automatic behavior. If you believe you know best, or more typically you want to choose the debug engine for a process using more than one code type, you can do so by clicking the "Select..." button, which should yield a "Select Code Type" dialog like this one: In this dialog you can switch to the debug engine you want to use by checking the box in front of your desired one, then hit "OK", then hit "Attach" to use it. Notice that the dialog suggests that you can select more than one. Not all combinations work (you'll get an error if you select two incompatible debug engines), but some do. Also notice in the list of debug engines one of the new players in Visual Studio 11, the GPU debug engine - I will be covering that on the C++ AMP team blog (and no, it cannot be combined with any others in this release). Comments about this post by Daniel Moth welcome at the original blog.

  • Slides and code for MPI Cluster Debugger

    I've blogged before about the MPI Cluster Debugger in VS2010 that facilitates launching the application on the cluster and attaching the debugger (btw, a shorter version of the screencast I link to there, is here).There have been requests for the code I use in the screencast, so please find a ZIP with that code.There have also been requests for a PowerPoint deck to use when showing this feature to others. Feel free to download some slides I threw together the other day. Comments about this post welcome at the original blog.

  • Deploying Socket.IO App to Windows Azure Web Site with Azure CLI

    - by shiju
    In this blog post, I will demonstrate how to deploy Socket.IO app to Windows Azure Website using Windows Azure Cross-Platform Command-Line Interface, which leverages the Windows Azure Website’s new support for Web Sockets. Recently Windows Azure has announced lot of enhancements including the support for Web Sockets in Windows Azure Websites, which lets the Node.js developers deploy Socket.IO apps to Windows Azure Websites. In this blog post, I am using  Windows Azure CLI for create and deploy Windows Azure Website. Install  Windows Azure CLI The Windows Azure CLI available as a NPM module so that you can install Windows Azure CLI using  NPM as shown in the below command. After installing the azure-cli, just enter the command “azure” which will show the useful commands provided by Azure CLI. Import Windows Azure Subscription Account In order to import our Azure subscription account, we need to download the Windows Azure subscription profile. The Azure CLI command “account download” lets you download the  Windows Azure subscription profile as shown in the below command. The command redirect you login to Windows Azure portal and allow you to download the Windows Azure publish settings file. The account import command lets you import the downloaded publish settings file so that you can create and manage Websites, Cloud Services, Virtual Machines and Mobile Services in Windows Azure. Create Windows Azure Website and Enable Web Sockets In this post, we are going to deploy Socket.IO app to Windows Azure Website by using the Web Socket support provided by Windows Azure. Let’s create a Website named “socketiochatapp” using the Azure CLI. The above command will create a Windows Azure Website that will also initialize a Git repository with a remote named Azure. We can see the newly created Website from Azure portal. By default, the Web Sockets will be disabled. So let’s enable it by navigating to the Configure tab of the Website, and select “ON” in Web Sockets option and save the configuration changes. Deploy a Node.js Socket.IO App to Windows Azure Now, our Windows Azure Website supports Web Sockets so that we can easily deploy Socket.IO app to Windows Azure Website. Let’s add Node.js chat app which leverages Socket.IO module. Please note that you have to add npm module dependencies in the package.json file so that Windows Azure can install the dependencies when deploying the app. Let’s add the Node.js app and add the files to git repository. Let’s commit the changes to git repository. We have committed the changes to git local repository. Let’s push the changes to Windows Azure production environment. The successful deployment can see from the Windows Azure portal by navigating to the deployments tab of the selected Windows Azure Website. The screen shot below shows that our chat app is running successfully.   You can follow me on Twitter @shijucv

  • SQL SERVER – Find Referenced or Referencing Object in SQL Server using sys.sql_expression_dependencies

    - by pinaldave
    A very common question which I often receive are: How do I find all the tables used in a particular stored procedure? How do I know which stored procedures are using a particular table? Both are valid question but before we see the answer of this question – let us understand two small concepts – Referenced and Referencing. Here is the sample stored procedure. CREATE PROCEDURE mySP AS SELECT * FROM Sales.Customer GO Reference: The table Sales.Customer is the reference object as it is being referenced in the stored procedure mySP. Referencing: The stored procedure mySP is the referencing object as it is referencing Sales.Customer table. Now we know what is referencing and referenced object. Let us run following queries. I am using AdventureWorks2012 as a sample database. If you do not have SQL Server 2012 here is the way to get SQL Server 2012 AdventureWorks database. Find Referecing Objects of a particular object Here we are finding all the objects which are using table Customer in their object definitions (regardless of the schema). USE AdventureWorks GO SELECT referencing_schema_name = SCHEMA_NAME(o.SCHEMA_ID), referencing_object_name = o.name, referencing_object_type_desc = o.type_desc, referenced_schema_name, referenced_object_name = referenced_entity_name, referenced_object_type_desc = o1.type_desc, referenced_server_name, referenced_database_name --,sed.* -- Uncomment for all the columns FROM sys.sql_expression_dependencies sed INNER JOIN sys.objects o ON sed.referencing_id = o.[object_id] LEFT OUTER JOIN sys.objects o1 ON sed.referenced_id = o1.[object_id] WHERE referenced_entity_name = 'Customer' The above query will return all the objects which are referencing the table Customer. Find Referenced Objects of a particular object Here we are finding all the objects which are used in the view table vIndividualCustomer. USE AdventureWorks GO SELECT referencing_schema_name = SCHEMA_NAME(o.SCHEMA_ID), referencing_object_name = o.name, referencing_object_type_desc = o.type_desc, referenced_schema_name, referenced_object_name = referenced_entity_name, referenced_object_type_desc = o1.type_desc, referenced_server_name, referenced_database_name --,sed.* -- Uncomment for all the columns FROM sys.sql_expression_dependencies sed INNER JOIN sys.objects o ON sed.referencing_id = o.[object_id] LEFT OUTER JOIN sys.objects o1 ON sed.referenced_id = o1.[object_id] WHERE o.name = 'vIndividualCustomer' The above query will return all the objects which are referencing the table Customer. I am just glad to write above query. There are more to write to this subject. In future blog post I will write more in depth about other DMV which also aids in finding referenced data.

  • Finally, I have my HP 6910p laptop running with 8Gb RAM

    - by Liam Westley
    Today, I received two Corsair Value Select 4Gb DDR SO-DIMMs (from overclock.co.uk) for my aging HP 6910p to give it the extra lease of life to keep it going until the end of 2010.  And here is the proof that Windows 7 64-bit happily sees all 8Gb, There are no 4Gb modules are officially supported for the HP 6910p (they didn’t exist when it was first build).  I was taking a bit of a gamble, and relying on the UK distance selling regulations which meant that even if they didn’t work I’d be able to send them back, getting a full refund and only paying for the return postage. I’d read Keith Comb’s blog back in 2008, (http://blogs.technet.com/b/keithcombs/archive/2008/07/05/loading-a-hp-6910p-with-8gb-of-ram.aspx) where he mentioned ‘trying’ out 4Gb samples of SO-DIMMs in a HP 6910p laptop, but there still appears to be no mentions of running this configuration in any other blog. Seeing how the 8Gb of memory is used is made easier with the new Resource Monitor available in Windows 7.  With two copies of Visual Studio 2008, Outlook, Firefox (with 30+ tabs), TweetDeck (an infamous memory hog) and VMWare workstation running a virtual machine allocated with 2Gb of memory, you might have no ‘free’ memory remaining, but the standby memory is an awesome 2.4Gb, and once the VM is up and running the Hard Faults/sec hovers around zero,   It’s the page fault figure which really counts, because reducing that value means that you are preventing the Windows 7 system drive from being used for virtual memory paging operations.  Even after only a few hours of use it’s noticeable that disc access has been reduced and applications feel more responsive and ‘snappy’.  I did consider the option of purchasing an SSD to replace the main drive, rather than go for 8Gb of RAM, but I think I’ve probably made the correct decision. Given my hobby topic of virtualisation, I take the view that you can never have too much memory.   It was also a decision made easier by the price differential between 8Gb of RAM compared to a decent size SSD.  In the 18 months since Keith Comb tested the first 4Gb SO-DIMMS they have plummeted in price, at just under £100 per 4Gb, they are around a fifth of the price when launched. So if you ever wondered if a HP 6910p can handle 8Gb, now you know.

  • Some of my favourite Visual Studio 2012 things&ndash;Teams

    - by Aaron Kowall
    Getting the balance right for when and how many team projects to create has always been a bit of a balance.  On large initiatives, there are often teams who work toward a common system.  These teams often have quite a bit of autonomy, but need to roll up to some higher level initiative.  In TFS 2010, people were often tempted to create separate Team Projects for each of the sub-teams and then do some magic with reporting and cross-team queries to get the consolidated view.  My recommendation was always to use Areas as a means of separating work across the team, but that always resulted in a large number of queries that need to be maintained and just seemed confusing.  When doing anything you had to remember to filter the query or view by Area in order to get correct results. Along with the awesome web access portal that comes in TFS 2012 (which I will cover details of in another post) the product group has introduced the concept of Teams.  A team is a sub-group within a TFS 2012 Team Project which allows us to more easily divide work along team boundaries. Technically, a Team is defined by an Area Path and a TFS Group, both of which could be done in TFS 2012.  However, by allowing for creation of a ‘Team’ in TFS 2012, the web portal is able to do a bunch of ‘magic’ for us.  We can view the project site (backlog, taskboard, etc) for the the team, we can assign items to the team and we can view the burndown for the team.  Basically, all the stuff that we had to prepare manually we now get created and managed for us with a nice UI. When you create a Team Project in TFS 2012, a ‘Default’ team is created with the same name as the Team Project.  So, if you only have 1 team working on the project, you are set.  If you want to divide the work into additional teams, you can create teams by using the Team Web Client. Teams are created using the ‘Administer Server’ icon in the top right of the web site.   You can select the team site by using the team chooser: Once you have selected a team, the Product Backlog, TaskBoard, Burndown Charts, etc. are all filtered to that team. NOTE: You always have the ability to choose the ‘Default’ team to see items for the entire project. PS: It’s been a long while since I shared on this blog.  To help with that I’m in a blogging challenge with some other developer and agilist friends.  Please check out their blogs as well: Steve Rogalsky: http://winnipegagilist.blogspot.ca Dylan Smith: http://www.geekswithblogs.net/optikal Tyler Doerkson: http://blog.tylerdoerksen.com David Alpert: http://www.spinthemoose.com Dave White: http://www.agileramblings.com   Technorati Tags: TFS 2012,Agile,Team

  • SQL SERVER – Inviting Ideas for SQL in Sixty Seconds – 12/12/12

    - by pinaldave
    Today is 12/12/12 – I am not sure when will I write this kind of date again – maybe never. This opportunity comes once in a lifetime when we have the same date, month and year all have same digit. December 12th is one of the most fantastic day in my personal life. Four years ago, this day I got married to my wife – Nupur Dave.  Here are photos of our wedding (Dec 12, 2008). Here is a very interesting photo of myself earlier this year. It is not photoshoped or modified photo. The only modification I have done here is to add arrow and speech bubble. Every Wednesday I tried to put one SQL in Sixty Seconds Video. The journey has been fantastic and so far I have put a total of 35 SQL in Sixty Seconds Video. The goal of the video is to learn something in 1 minute. In our daily life we are all very busy and hardly have time for anything. No matter how much we are busy – we all have one minute of time. Sometime we wait for a minute in elevators, at the escalator, at a coffee shop, or just waiting for our phone reboot. Today is a fantastic day – 12/12/12. Let me invite all of you submits SQL in Sixty Seconds idea. If I like your idea and create a sixty second video over it – you will win surprise learning material from me. There are two very simple rules of the contest: - I should have not have already recorded the tip. The tip should be descriptive. Do not just suggest to cover “Performance Tuning” or “How to Create Index” or “More of reporting services”. The tip should have around 100 words of description explaining SQL Tip. The contest is open forever. The winner will be announced whenever I use the tip to convert to video. If I use your tip, I will for sure mention in the blog post that it is inspired from your suggestion. Meanwhile, do not forget to subscribe YouTube Channel. Here are my latest three videos from SQL in Sixty Seconds.

  • Is MVVM in WPF outdated?

    - by Benjol
    I'm currently trying to get my head round MVVM for WPF - I don't mean get my head round the concept, but around the actual nuts and bolts of doing anything that is further off the beaten track than dumb CRUD. What I've noticed is that lots of the frameworks, and most/all blog posts are from 'ages' ago. Is this because it is now old hat and the bloggers have moved onto the Next Big Thing, or just because they've said everything there is to say? In other words, is there something I'm missing here?

  • A* navigational mesh path finding

    - by theguywholikeslinux
    So I've been making this top down 2D java game in this framework called Greenfoot [1] and I've been working on the AI for the guys you are gonna fight. I want them to be able to move around the world realistically so I soon realized, amongst a couple of other things, I would need some kind of pathfinding. I have made two A* prototypes. One is grid based and then I made one that works with waypoints so now I need to work out a way to get from a 2d "map" of the obstacles/buildings to a graph of nodes that I can make a path from. The actual pathfinding seems fine, just my open and closed lists could use a more efficient data structure, but I'll get to that if and when I need to. I intend to use a navigational mesh for all the reasons out lined in this post on ai-blog.net [2]. However, the problem I have faced is that what A* thinks is the shortest path from the polygon centres/edges is not necessarily the shortest path if you travel through any part of the node. To get a better idea you can see the question I asked on stackoverflow [3]. I got a good answer concerning a visibility graph. I have since purchased the book (Computational Geometry: Algorithms and Applications [4]) and read further into the topic, however I am still in favour of a navigational mesh (See "Managing Complexity" [5] from Amit’s Notes about Path-Finding [6]). (As a side note, maybe I could possibly use Theta* to convert multiple waypoints into one straight line if the first and last are not obscured. Or each time I move back check to the waypoint before last to see if I can go straight from that to this) So basically what I want is a navigational mesh where once I have put it through a funnel algorithm (e.g. this one from Digesting Duck [7]) I will get the true shortest path, rather than get one that is the shortest path following node to node only, but not the actual shortest given that you can go through some polygons and skip nodes/edges. Oh and I also want to know how you suggest storing the information concerning the polygons. For the waypoint prototype example I made I just had each node as an object and stored a list of all the other nodes you could travel to from that node, I'm guessing that won't work with polygons? and how to I tell if a polygon is open/traversable or if it is a solid object? How do I store which nodes make up the polygon? Finally, for the record: I do want to programme this by myself from scratch even though there are already other solutions available and I don't intend to be (re) using this code in anything other than this game so it does not matter that it will inevitably be poor quality. http://greenfoot.org http://www.ai-blog.net/archives/000152.html http://stackoverflow.com/q/7585515/ http://www.cs.uu.nl/geobook/ http://theory.stanford.edu/~amitp/GameProgramming/MapRepresentations.html http://theory.stanford.edu/~amitp/GameProgramming/ http://digestingduck.blogspot.com/2010/03/simple-stupid-funnel-algorithm.html

  • SQL SERVER – Introduction to PERCENTILE_DISC() – Analytic Functions Introduced in SQL Server 2012

    - by pinaldave
    SQL Server 2012 introduces new analytical function PERCENTILE_DISC(). The book online gives following definition of this function: Computes a specific percentile for sorted values in an entire rowset or within distinct partitions of a rowset in Microsoft SQL Server 2012 Release Candidate 0 (RC 0). For a given percentile value P, PERCENTILE_DISC sorts the values of the expression in the ORDER BY clause and returns the value with the smallest CUME_DIST value (with respect to the same sort specification) that is greater than or equal to P. If you are clear with understanding of the function – no need to read further. If you got lost here is the same in simple words – find value of the column which is equal or more than CUME_DIST. Before you continue reading this blog I strongly suggest you read about CUME_DIST function over here Introduction to CUME_DIST – Analytic Functions Introduced in SQL Server 2012. Now let’s have fun following query: USE AdventureWorks GO SELECT SalesOrderID, OrderQty, ProductID, CUME_DIST() OVER(PARTITION BY SalesOrderID ORDER BY ProductID ) AS CDist, PERCENTILE_DISC(0.5) WITHIN GROUP (ORDER BY ProductID) OVER (PARTITION BY SalesOrderID) AS PercentileDisc FROM Sales.SalesOrderDetail WHERE SalesOrderID IN (43670, 43669, 43667, 43663) ORDER BY SalesOrderID DESC GO The above query will give us the following result: You can see that I have used PERCENTILE_DISC(0.5) in query, which is similar to finding median but not exactly. PERCENTILE_DISC() function takes a percentile as a passing parameters. It returns the value as answer which value is equal or great to the percentile value which is passed into the example. For example in above example we are passing 0.5 into the PERCENTILE_DISC() function. It will go through the resultset and identify which rows has values which are equal to or great than 0.5. In first example it found two rows which are equal to 0.5 and the value of ProductID of that row is the answer of PERCENTILE_DISC(). In some third windowed resultset there is only single row with the CUME_DIST() value as 1 and that is for sure higher than 0.5 making it as a answer. To make sure that we are clear with this example properly. Here is one more example where I am passing 0.6 as a percentile. Now let’s have fun following query: USE AdventureWorks GO SELECT SalesOrderID, OrderQty, ProductID, CUME_DIST() OVER(PARTITION BY SalesOrderID ORDER BY ProductID ) AS CDist, PERCENTILE_DISC(0.6) WITHIN GROUP (ORDER BY ProductID) OVER (PARTITION BY SalesOrderID) AS PercentileDisc FROM Sales.SalesOrderDetail WHERE SalesOrderID IN (43670, 43669, 43667, 43663) ORDER BY SalesOrderID DESC GO The above query will give us the following result: The result of the PERCENTILE_DISC(0.6) is ProductID of which CUME_DIST() is more than 0.6. This means for SalesOrderID 43670 has row with CUME_DIST() 0.75 is the qualified row, resulting answer 773 for ProductID. I hope this explanation makes it further clear.
