  • Row Count Plus Transformation

    As the name suggests we have taken the current Row Count Transform that is provided by Microsoft in the Integration Services toolbox and we have recreated the functionality and extended upon it. There are two things about the current version that we thought could do with cleaning up Lack of a custom UI You have to type the variable name yourself In the Row Count Plus Transformation we solve these issues for you. Another thing we thought was missing is the ability to calculate the time taken between components in the pipeline. An example usage would be that you want to know how many rows flowed between Component A and Component B and how long it took. Again we have solved this issue. Credit must go to Erik Veerman of Solid Quality Learning for the idea behind noting the duration. We were looking at one of his packages and saw that he was doing something very similar but he was using a Script Component as a transformation. Our philosophy is that if you have to write or Copy and Paste the same piece of code more than once then you should be thinking about a custom component and here it is. The Row Count Plus Transformation populates variables with the values returned from; Counting the rows that have flowed through the path Returning the time in seconds between when it first saw a row come down this path and when it saw the final row. It is possible to leave both these boxes blank and the component will still work.   All input columns are passed through the transformation unaltered, you are not permitted to change or add to the inputs or outputs of this component. Optionally you can set the component to fire an event, which happens during the PostExecute phase of the execution. This can be useful to improve visibility of this information, such that it is captured in package logging, or can be used to drive workflow in the case of an error event. Properties Property Data Type Description OutputRowCountVariable String The name of the variable into which the amount of row read will be passed (Optional). OutputDurationVariable String The name of the variable into which the duration in seconds will be passed. (Optional). EventType RowCountPlusTransform.EventType The type of event to fire during post execute, included in which are the row count and duration values. RowCountPlusTransform.EventType Enumeration Name Value Description None 0 Do not fire any event. Information 1 Fire an Information event. Warning 2 Fire a Warning event. Error 3 Fire an Error event. Installation The component is provided as an MSI file which you can download and run to install it. This simply places the files on disk in the correct locations and also installs the assemblies in the Global Assembly Cache as per Microsoft’s recommendations. You may need to restart the SQL Server Integration Services service, as this caches information about what components are installed, as well as restarting any open instances of Business Intelligence Development Studio (BIDS) / Visual Studio that you may be using to build your SSIS packages. For 2005/2008 Only - Finally you will have to add the transformation to the Visual Studio toolbox manually. Right-click the toolbox, and select Choose Items.... Select the SSIS Data Flow Items tab, and then check the Row Count Plus Transformation in the Choose Toolbox Items window. This process has been described in detail in the related FAQ entry for How do I install a task or transform component? We recommend you follow best practice and apply the current Microsoft SQL Server Service pack to your SQL Server servers and workstations, and this component requires a minimum of SQL Server 2005 Service Pack 1. Downloads The Row Number Transformation is available for SQL Server 2005, SQL Server 2008 (includes R2) and SQL Server 2012. Please choose the version to match your SQL Server version, or you can install multiple versions and use them side by side if you have more than one version of SQL Server installed. Row Count Plus Transformation for SQL Server 2005 Row Count Plus Transformation for SQL Server 2008 Row Count Plus Transformation for SQL Server 2012 Version History SQL Server 2012 Version 3.0.0.6 - SQL Server 2012 release. Includes upgrade support for both 2005 and 2008 packages to 2012. (5 Jun 2012) SQL Server 2008 Version 2.0.0.5 - SQL Server 2008 release. (15 Oct 2008) SQL Server 2005 Version 1.1.0.43 - Bug fix for duration. For long running processes the duration second count may have been incorrect. (8 Sep 2006) Version 1.1.0.42 - SP1 Compatibility Testing. Added the ability to raise an event with the count and duration data for easier logging or workflow. (18 Jun 2006) Version 1.0.0.1 - SQL Server 2005 RTM. Made available as general public release. (20 Mar 2006) Screenshot Troubleshooting Make sure you have downloaded the version that matches your version of SQL Server. We offer separate downloads for SQL Server 2005, SQL Server 2008 and SQL Server 2012. If you get an error when you try and use the component along the lines of The component could not be added to the Data Flow task. Please verify that this component is properly installed.  ... The data flow object "Konesans ..." is not installed correctly on this computer, this usually indicates that the internal cache of SSIS components needs to be updated. This is held by the SSIS service, so you need restart the the SQL Server Integration Services service. You can do this from the Services applet in Control Panel or Administrative Tools in Windows. You can also restart the computer if you prefer. You may also need to restart any current instances of Business Intelligence Development Studio (BIDS) / Visual Studio that you may be using to build your SSIS packages. Once installation is complete you need to manually add the task to the toolbox before you will see it and to be able add it to packages - How do I install a task or transform component?

  • How to update a game off a database

    - by James Clifton
    I am currently writing a sports strategy management game (cricket) in PHP, with a MYSQL database, and I have come across one stumbling block - how do I update games where neither player is online? Cricket is a game played between two players, and when they (or one of them) is online then everything is fine; but what if neither player is online? This occurs when championship games are played, and these games need to happen at certain times for game reasons. At the moment I have a private web page that updates every 5 seconds, and each time it loads all games are updated; but then I have the problem that when my private web page stops (for example my computer crashes or my web browser plays up) the game stops updating! Any suggestions?

  • How can I send audio input as chunked HTTP?

    - by Noli
    I am trying to create an interface with an external server, and don't know where to start. I would need to take audio as input to my computer, and send it to the remote server as a chunked HTTP request. The api that i'm trying to connect to is described here p1-5 http://dragonmobile.nuancemobiledeveloper.com/public/Help/HttpInterface/HTTP_Services_for_NDEV_v1.2_Silver_Version.pdf I have never worked with audio programmatically, so don't know what would be the most straighforward way to go about this? Are there solutions that exist out there that already do this? I've come across references to Shoutcast, VLC, Icecast, FFMPeg, Darkice, but I don't know if those are appropriate for what I'm trying to accomplish or not. Would appreciate any guidance, Thanks

  • Only recognizes one partition from multi partitions SD card

    - by Jay Ngo
    Hello everybody, I split my sd card into 2 partitions. When i use usb-card-reader to read my sd card, only the one partition shows up on the screen, the other doesn't. I have run the command "sudo fdisk -l" and the result is the same, only one partition is recognized. But i do believe both partitions of my sd card work fine, because i still can boot my single-board computer with that sd card and run some programms, which are inside that unreadable partition. How can i access both partitions of my sd card? Does anyone know how to solve this kind of problem? I really appreciate your help.

  • Automatically select headphones when plugged in

    - by Joachim Pileborg
    When I plug headphones into my desktop computer, they are not automatically selected for output, instead all sound still goes through my S/PDIF output to the stereo. The headphones alternative is added in the sound settings, and I have to manually select it as output device. $ cat /proc/asound/pcm 00-00: ALC898 Analog : ALC898 Analog : playback 1 : capture 1 00-01: ALC898 Digital : ALC898 Digital : playback 1 00-02: ALC898 Analog : ALC898 Analog : capture 2 I have done a Google search, as well as search askubuntu.com, but none of the answers in the hits I found seems to help. Also, after listening with the headphones and then unplug them, the previous output is not automatically selected, so I have no sound at all then. I have to manually select the correct output in the settings.

  • How do I resolve "No JSON object could be decoded" on mythbuntu live CD?

    - by Neil
    I have been running a MythTV frontend on my laptop for some time against a MythTV backend installed in Linux Mint 12 on another computer, and everything works fine. Now, I'm trying out the Mythbuntu Live CD (12.04.1 32-bit) on the laptop, to turn it into a dedicated front end. It's connecting to the network just fine, and I can see my server. When I click on the frontend icon on the desktop, it asks me for the security code, which I've verified against mythtv-setup on the server. However, when I test that code, it shows the error message "No JSON object could be decoded". I've looked in the control center to see if there's something else I should be setting up. The message above implies to me that it can't find the server, but I can find no place in the control center to tell it where to find my myth backend, which I find a little odd. Does the live CD not work against a backend server on another machine?

  • Formatted Ubuntu partition & now grub says "error: no such partition" - can't enter windows

    - by qwBJ
    I had installed Ubuntu (current version: 11.xx) alongside Windows Vista. Now I formatted the Ubuntu partition & merged it with another partition (without thinking, obviously). Now, when I restart the computer, GRUB probably tries to find the old partition (which does no longer exist) and says: error: no such partition. grub rescue> Now I dont know what to do (I'm a total beginner). I tried to re-install Ubuntu on the newly formatted partition but this won't work, because after removing the install-usb (which I am said to do during installation) I find the above error-message again. I guess I need some way to reconfigure grub OR to reinstall grub/ubuntu (on the newly formatted partition) OR to reinstall the windows boot manager (without reinstall. Windows), but I have no idea how to do either of these things.

  • Is there an algorithm for a pool game?

    - by Dmitri
    Hello! I am looking for algorithm to calculate direction and speed of balls in a pool game. I am sure there has to be some type of open source code for this since pool games are some of the oldest computer games I can remember. I mean, when one ball hits another, I need a algorithm to calculate direction of both of them. It will depend of exact angle of where they hit each other and on speed. I want to practice Java coding, so I am looking for java code or package that has this type of code.

  • Learning Python is good?

    - by user15220
    Recently I have seen some videos from MIT on computer programming topics. I found it's really worth watching. Especially the concepts of algorithms and fundamental stuffs. The programs were written and explained in Python. I never had looked into this language before as I learned and doing stuffs with C/C++ programming. But the cleanliness and better readability of syntax attracted me. Of course as a C++ programmer for long time it's the most readable language for me. Also I heard Python library contains solid algorithms and data-structures implementations. Can you share your experience in this language?

  • How to use MythBuntu to send TV signal to a 2nd frontend

    - by Mark Preston
    I guess the a MythTV or MythBuntu backend acts as a "server" for the frontends. I have MythBuntu installed. It runs fine, I can tune live TV, hear the sound, etc. To get this to work, I had to config the Wired Network IP4V settings to Method: Link-Local Only. The Local Backend IP address is: 127.0.0.1 and the info (bottom of screen) says that if there is another frontend, that this IP add. must be changed. 1 - Does this mean changed to the IP address of the 2nd frontend? 2 - What "Method" do I use to make 2 or more frontends? 3 - I have an ethernet switch which currently "sees" the tv signal, sends it to the computer's ethernet port where Mythbuntu makes use of it. 4 - How do I set up the Myth to send it's output (the tv shows) to both televisions? If you know of a How-To, or website, please give the URL or identifying keywords.

  • What is the *correct* term for a program that makes use of multiple hardware processor cores?

    - by Ryan Thompson
    I want to say that my program is capable of splitting some work across multiple CPU cores on a single system. What is the simple term for this? It's not multi-threaded, because that doesn't automatically imply that the threads run in parallel. It's not multi-process, because multiprocessing seems to be a property of a computer system, not a program. "capable of parallel operation" seems too wordy, and with all the confusion of terminology, I'm not even sure if it's accurate. So is there a simple term for this?

    Possible Duplicate: My computer boots to a black screen, what options do I have to fix it? From my Windows XP SP3 machine, I downloaded the live image file for Ubuntu 12.04 LTS. I then burned a bootable CD. Then I went into the BIOS and set installation settings to (first) CD drive and (second) disabled. However, when I boot I only get a black screen with a blinking cursor.

  • Compute if a function is pure

    - by Oni
    As per Wikipedia: In computer programming, a function may be described as pure if both these statements about the function hold: The function always evaluates the same result value given the same argument value(s). The function result value cannot depend on any hidden information or state that may change as program execution proceeds or between different executions of the program, nor can it depend on any external input from I/O devices. Evaluation of the result does not cause any semantically observable side effect or output, such as mutation of mutable objects or output to I/O devices. I am wondering if it is possible to write a function that compute if a function is pure or not. Example code in Javascript: function sum(a,b) { return a+b; } function say(x){ console.log(x); } isPure(sum) // True isPure(say) // False

  • Changing permissions on serial port

    - by Terrik
    I'm using the Arduino IDE in Ubuntu, and am having issues with the serial port. It has worked in the past, but for reasons that may be unnecesary, I felt the need to change the ownership of some of the files from root ownership to my users ownership. This made the IDE work correctly, but I lost the ability to use the correct serial port. In the dev folder, the port I need is listed as permission 166. Someone (who is no longer in the area to help me) swapped the permissions to 666, which made it all work gloriously. However, it reverted back as soon as I restarted my computer, and if I now try to use the command: sudo chmod 666 ttyACM0 nothing happens. No error messages, but no permission change either. How can I change it, and how can I get it to change permanently. I apologize if this question is overly simplistic or unclear, I'm an ubuntu noob, and I wouldn't begrudge feedback!

  • 3D engine for an online city/country simulation game (SimCity, Civilization)

    - by Dmitri
    I want to create a browser game, in which the user can control the development of a certain region (like SimCity or Civilization). One part of the task is rendering of the virtual world in a browser (3D or pseudo-3D). The rendering engine should a) work in a browser and b) ideally - be compatible with mobile devices (i. e. the representation of the virtual world should be visible both on desktop computer and mobile devices with the same codebase). Question: Which rendering engines (for SimCity-style games) fulfill aforementioned requirements (open and closed source) ?

  • LaTeX-like display programming environment

    - by Gage
    I used to be a hobbyist programmer, but now I'm also a fairly experienced physicist and find myself programming to solve certain problems quite a lot. In physics, we use variables with superscripts, subscripts, italics, underlines, etc etc. To bridge this gap to the computer we usually use LaTeX. Now, I generally use MATLAB for handling any data and such, and find it very irritating that I can't basically use LaTeX for variable names. Something as simple as sy has to be named either sigma_y or some descriptive name like peak_height_error. I don't necessarily want full on workable LaTeX in my code, but I do want to be able to use greek letters and super/sub-scripts at the very least. Does this exist?
