  • Monitor network connectivity in WP7 apps

    - by Daniel Moth
    Most interesting Windows Phone apps rely on some network service for their functionality. So at some point in your app you may need to know programmatically if there is network connection available or not. For example, the Translator by Moth app relies on the Bing Translation service for translations. When a request for translation (text or voice) is made, the network call may fail. The failure reason is not evident from any of the return results, so I check the connection to see if it is present. Dependent on that, a different message is shown to the user. Before the translation phase is even reached, at the app start up time the Bing service is queried for its list of  languages; in that case I don't want to show the user a message and instead want to be notified when the network is available in order to send the query out again. So for those two requirements (which I imagine are common in other apps) I wrote a simple wrapper MyNetwork static class to the framework APIs: Call once MyNetwork.MonitorNetworkAvailability() method so it monitors the network change At any time check the MyNetwork.IsConnected property to check for network presence Subscribe to its MyNetwork.ConnectionEstablished event Optionally, during debugging use its MyNetwork.ChangeStatus method to simulate a change in network status As usual, there may be better ways to achieve this, but this class works perfectly for my scenarios. You can download the code here: MyNetworks.cs. Comments about this post welcome at the original blog.

  • Supporting copy 'n paste in your Windows Phone app

    - by Daniel Moth
    Some Windows Phone 7 owners already have the NoDo update, and others are getting it soon. This update brings, among other things, copy & paste support for text boxes. The user taps on a piece of text (and can drag in either direction to select more/less words), a popup icon appears that when tapped copies the text to the clipboard, and then at any app that shows the soft input panel there is an icon option to paste the copied text into the associated textbox. For more read this 'how to'. Note that there is no programmatic access to the clipboard, only the end user experience I just summarized, so there is nothing you need to do for your app's textboxes to support copy & paste: it just works. The only issue may be if in your app you use static TextBlock controls, for which the copy support will not appear, of course. That was the case with my Translator by Moth app where the translated text appears in a TextBlock. So, I wanted the user to be able to copy directly from the translated text (without offering an editable TextBox for an area where user input does not make sense). Take a look at a screenshot of my app before I made any changes to it. I then made changes to it preserving the look and feel, yet with additional copy support (see screenshot on the right)! So how did I achieve that? Simply by using my co-author's template (thanks Peter!): Copyable TextBlock for Windows Phone.   (aside: in my app even without this change there is a workaround, the user could use the "swap" feature to swap the source and target, so they can copy from the text box) Comments about this post welcome at the original blog.

  • EPM troubleshooting Utilities

    - by THE
    (in via Maurice) "Are you keeping up-to-date with the latest troubleshooting utilities introduced from EPM 11.1.2.2? These are typically not described in product documentation, so you might miss references to them. The following five utilities may be run from the command line.(1) Deployment Report was introduced with EPM 11.1.2.2 (11 April 2012). It details logical web addresses, web servers, application ports, database connections, user directories, database repositories configured for the EPM system, data directories used by EPM system products, instance directories, FMW homes, deployment distory, et cetera. It also helps to keep you honest about whether you made changes to the system and at what times! Download Shared Services patch 13530721 to get the backported functionality in EPM 11.1.2.1. Run it from /Oracle/Middleware/user_projects/epmsystem1/bin/epmsys_registry.sh report deployment (on Unix/Linux)\Oracle\Middleware\user_projects\epmsystem1\bin\epmsys_registry.bat report deployment (on Microsoft Windows). The output is saved under \Oracle\Middleware\user_projects\epmsystem1\diagnostics\reports\deployment_report.html (2) Log Analysis has received more "press". It was released with EPM 11.1.2.3 and helps the user to slice and dice EPM logs. It has many parameters which are documented when run without parameters, when run with the -h parameter, or in the 'Readme' file. It has also been released as a standalone utility for EPM 11.1.2.3 and earlier versions. (Sign in to  My Oracle Support, click the 'Patches & Updates' tab, enter the patch number 17425397, and click the Search button. Download the appropriate platform-specific zip file, unzip, and read the 'Readme' file. Note that you must provide a proper value to a JAVA_HOME environment variable [pointer to the mother directory of the Java /bin subdirectory] in the loganalysis.bat | .sh file and use the -d parameter when running standalone.) Run it from /Oracle/Middleware/user_projects/epmsystem1/bin/loganalysis.sh -h (on Unix/Linux)\Oracle\Middleware\user_projects\epmsystem1\bin\loganalysis.bat -h (on Microsoft Windows). The output is saved under the \Oracle\Middleware\user_projects\epmsystem1\diagnostics\reports\ subdirectory. (3) The Registry Cleanup command may be used (without fear!) to clean up various corruptions which can  affect the Hyperion (database-based) Repository. Run it from /Oracle/Middleware/user_projects/epmsystem1/bin/registry-cleanup.sh (on Unix/Linux)\Oracle\Middleware\user_projects\epmsystem1\bin\registry-cleanup.bat (on Microsoft Windows). The actions are described on the command line. (4) The Remove Instance Command is only used if there are two or more instances configured on one computer and one of those should be deleted. Run it from /Oracle/Middleware/user_projects/epmsystem1/bin/remove-instance.sh (on Unix/Linux)\Oracle\Middleware\user_projects\epmsystem1\bin\remove-instance.bat (on Microsoft Windows). (5) The Reset Configuration Tool was introduced with EPM 11.1.2.2. It nullifies Shared Services Hyperion Registry settings so that a service may be reconfigured. You may locate the values to substitute for <product> or <task> by scanning registry.html (generated by running epmsys_registry.bat | .sh). Find productNAME in INSTANCE_TASKS_CONFIGURATION and SYSTEM_TASKS_CONFIGURATION nodes and identify tasks by property pairs that have values of 'Configurated' or 'Pending'. Run it from /Oracle/Middleware/user_projects/epmsystem1/bin/resetConfigTask.sh -product <product> -task <task> (on Unix/Linux)\Oracle\Middleware\user_projects\epmsystem1\bin\resetConfigTask.bat -product <product> -task <task> (on Microsoft Windows). "Thanks to Maurice for this collection of utilities.

  • Speaking at AMD Fusion conference

    - by Daniel Moth
    Next Wednesday at 2pm I will be presenting a session at the AMD Fusion developer summit in Bellevue, Washington State. For more on this conference please visit the official website. If you filter the catalog by 'Speaker Last Name' to "Moth", you'll find my talk. For your convenience, below is the title and abstract Blazing-fast code using GPUs and more, with Microsoft Visual C++ To get full performance out of mainstream hardware, high-performance code needs to harness, not only multi-core CPUs, but also GPUs (whether discrete cards or integrated in the processor) and other compute accelerators to achieve orders-of-magnitude speed-up for data parallel algorithms. How can you as a C++ developer fully utilize all that heterogeneous hardware from your Visual Studio environment? How can your code benefit from this tremendous performance boost without sacrificing your developer productivity or the portability of your solution? The answers will be presented in this session that introduces a new technology from Microsoft. Hope to see many of you there! Comments about this post welcome at the original blog.

  • C++ Accelerated Massive Parallelism

    - by Daniel Moth
    At AMD's Fusion conference Herb Sutter announced in his keynote session a technology that our team has been working on that we call C++ Accelerated Massive Parallelism (C++ AMP) and during the keynote I showed a brief demo of an app built with our technology. After the keynote, I go deeper into the technology in my breakout session. If you read both those abstracts, you'll get some information about what C++ AMP is, without being too explicit since we published the abstracts before the technology was announced. You can find the official online announcement at Soma's blog post. Here, I just wanted to capture the key points about C++ AMP that can serve as an introduction and an FAQ. So, in no particular order… C++ AMP lowers the barrier to entry for heterogeneous hardware programmability and brings performance to the mainstream, without sacrificing developer productivity or solution portability. is designed not only to help you address today's massively parallel hardware (i.e. GPUs and APUs), but it also future proofs your code investments with a forward looking design. is part of Visual C++. You don't need to use a different compiler or learn different syntax. is modern C++. Not C or some other derivative. is integrated and supported fully in Visual Studio vNext. Editing, building, debugging, profiling and all the other goodness of Visual Studio work well with C++ AMP. provides an STL-like library as part of the existing concurrency namespace and delivered in the new amp.h header file. makes it extremely easy to work with large multi-dimensional data on heterogeneous hardware; in a manner that exposes parallelization. introduces only one core C++ language extension. builds on DirectX (and DirectCompute in particular) which offers a great hardware abstraction layer that is ubiquitous and reliable. The architecture is such, that this point can be thought of as an implementation detail that does not surface to the API layer. Stay tuned on my blog for more over the coming months where I will switch from just talking about C++ AMP to showing you how to use the API with code examples… Comments about this post welcome at the original blog.

  • Heading to GTC 2010

    - by Daniel Moth
    Next week the GPU Technology Conference (GTC) 2010 takes place in San Jose, CA and I am lucky enough to be attending the entire week. It has been an extremely long time (in fact, I can't remember the last time) where I am registered as an attendee at a conference (full pass/access) without being a speaker *and* without having any booth duty! Having said that, we (our team at Microsoft) will be running GPU debugging UX studies throughout the entire week (similar to what I had previously advertised). If you are attending GTC 2010 and you are interested, look for the related flyer in your conference bag. The conference is an excellent opportunity to connect in-person with various individuals that I have only met virtually. From an educational perspective there is a very long and interesting session list, with multiple concurrent slots, making it very hard to choose between them, but I have managed to create my (packed) schedule. I am most looking forward to sessions on the programming languages and tools, both from Microsoft and MS partners. For full conference details, visit the GTC 2010 official page.

  • Join our team at Microsoft

    - by Daniel Moth
    If you are looking for a SDE or SDET job at Microsoft, keep on reading. Back in January I posted a Dev Lead opening on our team, which was quickly filled internally (by Maria Blees). Our team is part of the recently announced Microsoft Technical Computing group. Specifically, we are working on new debugger functionality, integrated with Visual Studio (we are starting work on the next version), aimed to address HPC and GPGPU scenarios (and continuing the Parallel Debugging scenarios we started addressing with VS2010). We now have many more openings on our debugger team. We posted three of those on the careers website: Software Development Engineer Software Development Engineer II Software Development Engineer in Test II (don't let the word "Test" fool you: An SDET on our team is no different than a developer in any way, including the skills required) Please do read the contents of the links above. Specifically, note that for both positions you need to be as proficient in writing C++ code as you are with managed code (WPF experience is a plus). If you think you have what it takes, you wish to join a quality and schedule driven project, and want to contribute features to a product that has global impact, then send me your resume and I'll pass it on to the hiring managers.

  • User eXperience

    - by Daniel Moth
    The last few months I have been spending a lot of time designing (and help design) the developer experience for the areas I contribute to (in future versions of Visual Studio). As a technical person who defines feature sets, it is easy to get engulfed in the pure technical side of things and ignore the details that ultimately make users "love" using the product to achieve their goal, instead of just "having to use" it. Engaging in UX design helps me escape that trap. In case you are also interested in the UX side of development, I thought I'd share an interesting site I came across: UX myths. In particular, I recommend reading myths 9, 10, 12, 13, 14, 15 and 21. Let me know if there are other UX resources you recommend… Comments about this post welcome at the original blog.

  • Please Help Me Install Firestorm?

    - by Elle Caszatt
    I have been trying for hours just to install one program. In this time, I've tried my best to follow directions and not screw everything up but I have. I'm new to Linux. I tried to install Firestorm and this is what happened: parent@ubuntu:~$ sudo '/home/parent/Downloads/Phoenix_Firestorm-Release_i686_4.2.1.29803/install.sh' [sudo] password for parent: Enter the desired installation directory [/opt/firestorm-install]: /home/parent/downloads - Installing to /home/parent/downloads /home/parent/Downloads/Phoenix_Firestorm-Release_i686_4.2.1.29803/install.sh: line 80: /home/parent/downloads/etc/refresh_desktop_app_entry.sh: Permission denied parent@ubuntu:~$ sudo opt/firestorm-install sudo: opt/firestorm-install: command not found parent@ubuntu:~$ ./etc/refresh_desktop_app_entry.sh bash: ./etc/refresh_desktop_app_entry.sh: No such file or directory parent@ubuntu:~$ sudo '/home/parent/Downloads/Phoenix_Firestorm-Release_i686_4.2.1.29803/install.sh' Enter the desired installation directory [/opt/firestorm-install]: /home/parent - Backing up previous installation to /home/parent.backup-2012-08-27 - Installing to /home/parent cp: cannot stat `/home/parent/Downloads/Phoenix_Firestorm-Release_i686_4.2.1.29803/*': No such file or directory Failed parent@ubuntu:~$ Now whenever I go into my files it says it can't find anything. Like Cannot find home/parent/Downloads. Now, I KNOW there are downloads. I don't know why it's doing this all of a sudden. I'm so frustrated that I'm ready to just go back to Windows. I've already had to uninstall/reinstall Ubuntu once today. It's looking like I"m going to have to do it again. How can I fix my file problem that I'm now having and can someone please, please tell me how to install Firestorm? I mean they don't even have their repository listed. It's ridiculous to have to go through this over a program. Spotify wasn't hard at all to install so why is this? Someone please help, and I'm sorry if I sound like a total idiot. I'm pretty tech savvy but I'm honestly pretty upset after struggling with this for hours. Edit Okay, I see the problem with the directory files (showing the error I mentioned above when I try to click on them). I can only access my downloads, desktop, ect, through the backup that was created when I tried to install Firestorm. It's like that's the real home now. How can I get it back to the way it was? Edit Ubuntu has stopped working for me on reboot now. It doesn't go past the login screen. This is exactly what happened when I had to uninstall it before after trying to install Firestorm. Maybe I'm giving up too easily but I think I'm just going to go back to Windows. If this is what's going to happen every time I innocently try to install a program then it's just not worth it. I installed it specifically to run Firestorm because Windows sucks up a lot of CPU and causes lag. I still appreciate any input but this is just too much hassle for something that shouldn't be hard.

  • "Hello World" in C++ AMP

    - by Daniel Moth
    Some say that the equivalent of "hello world" code in the data parallel world is matrix multiplication :) Below is the before C++ AMP and after C++ AMP code. For more on what it all means, watch the recording of my C++ AMP introduction (the example below is part of the session). void MatrixMultiply(vector<float>& vC, const vector<float>& vA, const vector<float>& vB, int M, int N, int W ) { for (int y = 0; y < M; y++) { for (int x = 0; x < N; x++) { float sum = 0; for(int i = 0; i < W; i++) { sum += vA[y * W + i] * vB[i * N + x]; } vC[y * N + x] = sum; } } } Change the function to use C++ AMP and hence offload the computation to the GPU, and now the calling code (which I am not showing) needs no changes and the overall operation gives you really nice speed up for large datasets…  #include <amp.h> using namespace concurrency; void MatrixMultiply(vector<float>& vC, const vector<float>& vA, const vector<float>& vB, int M, int N, int W ) { array_view<const float,2> a(M, W, vA); array_view<const float,2> b(W, N, vB); array_view<writeonly<float>,2> c(M, N, vC); parallel_for_each( c.grid, [=](index<2> idx) mutable restrict(direct3d) { float sum = 0; for(int i = 0; i < a.x; i++) { sum += a(idx.y, i) * b(i, idx.x); } c[idx] = sum; } ); } Again, you can understand the elements above, by using my C++ AMP presentation slides and recording… Stay tuned for more… Comments about this post welcome at the original blog.

  • C++ AMP recording and slides

    - by Daniel Moth
    Yesterday we announced C++ Accelerated Massive Parallelism. Many of you want to know more about the API instead of just meta information. I will trickle more code over the coming months leading up to the date when we will share actual bits. Until you have bits in your hand, it is only your curiosity that is blocked, so I ask you to be patient with that and allow me to release this on our own schedule ;-) You can now watch my 45-minute session introducing C++ AMP on channel9. You will also want to download the slides (pdf), because they are not readable in the recording. Comments about this post welcome at the original blog.

  • How to Install WebLogic 12c ZIP on Linux

    - by Bruno.Borges
    I knew that WebLogic had this small ZIP distribution, of only 184M, but what I didn't know was that it is so easy to install it on Linux machines, specially for development purposes, that I thought I had to blog about it. You may want to check this blog, where I found the missing part on this how to, but I'm blogging this again because I wanted to put it in a simpler way, straight to the point. And if you are looking for a how to for Mac, check Arun Gupta's post.  So, here's the step-by-step: 1 - Download the ZIP distribution (don't worry if your system is x86_64)Don't forget to accept the OTN Free Developer License Agreement! 2 - Choose where to install your WebLogic server and your domain, and set as your MW_HOME environment variableI will use /opt/middleware/weblogic for this how to export MW_HOME=/opt/middleware/weblogicMake sure this path exists in your system. 'mydomains' will be used to keep your WebLogic domain. mkdir -p $MW_HOME/mydomain 3 - If you don't have your JAVA_HOME environment variable still configured, do it. Point it to where your JDK is installed. export JAVA_HOME=/usr/lib/jvm/default-java 4 - Unzip the downloaded file into MW_HOME unzip wls1211_dev.zip -d $MW_HOME 5 - Go to that directory and run configure.sh cd $MW_HOME ./configure.sh 6 - Call the setEnvs.sh script . $MW_HOME/wlserver/server/bin/setWLSEnv.sh7 - Create your development domain. It will ask you for username and password. I like to use weblogic / welcome1cd $MW_HOME/mydomain $JAVA_HOME/bin/java $JAVA_OPTIONS -Xmx1024m \ -Dweblogic.management.allowPasswordEcho=true weblogic.Server8 - Start WebLogic and access its web console(sh startWebLogic.sh &); sleep 10; firefox http://localhost:7001/consoleUsually, it takes only 10 seconds to start a domain, and 5 more to deploy the Administration Console (on my laptop). :-)Enjoy!

  • could not save the file /usr/... permission denied (13.04)

    - by plaguedoctor
    I am running Ubuntu 13.04 and am trying to create an .sh file for conky in /usr/bin using gedit. When trying to save I get the error dialogue: Could not save the file /usr/bin/conky-start.sh You do not have the permissions necessary to save the file. Please check that you typed the location correctly and try again." From searching, I think I have to run a command in terminal to allow permission, but I couldn't find out what that is. Edit: I'm trying to create the file conky-start.sh, not change or run it. Thus far, I've opened gedit, copied and pasted some required info from the net, and I'm trying to save-as /usr/bin/conky-start.sh Perhaps I need to create the file first in terminal, then edit it? How would I do that?

  • Cron won't execute if am not logged in

    - by JonaMX
    I have a cron that makes a backup of MySql, if I execute on shell it works pretty well even if I'm logged when cron supposed to execute works fine, but if I'm not logged just won't execute, I don't know what could happened, any suggestion ? Crontab 00 04 * * * /home/administrador/scripts/respaldo.sh respaldo.sh #!/bin/sh mysql -uroot -p[PASS] ccs < /home/administrador/scripts/limpia.sql mysqldump -uroot -p[PASS] --routines ccs > /home/administrador/backups/backup_$(date +%Y%m%d).sql mysqlcheck -uroot -p[PASS] --auto-repair --optimize ccs cd /home/administrador/backups/ tar -zcf backup_$(date +%Y%m%d).tgz backup_$(date +%Y%m%d).sql rm backup_$(date +%Y%m%d).sql find -name '*.tgz' -type f -mtime +90 -exec rm -f {} \; respaldo.sh has execute permission SOLUTION The problema was that the /home/adminsitrador directory was an encrypted folder so when the user is logged in the folder it's decrypted and everything works but when the user it's logged off the folder it's encrypted and the cron can't access to that path, so I've changed the cron script and backup to another unencrypted folder and to root user and now everything it's working pretty well, thanks to all for your help !

  • Specific cron at time point [closed]

    - by ARTI
    I have a very specific task, but can't handle it. I am not a programmer and totally n00b on bash scritps. So the question is, how to create a cron job like this: Script A.sh could be called at any time by hands, and it should create cron job to run script B.sh once at the nearest time point. For example I will have 4 time points: 10.00pm, 10.15pm, 10.30pm, 10.45pm. So if trigger a script A.sh at 10.07pm it should creat cron job to run ONCE script B.sh at 10.15h, because 10.15h is the nearest time point in future. Is it possible? How can I write such script A.sh? I use Centos 6 It is very important and urgent for me. Thank you very much.

  • Depth Map resolution shifting

    - by user3669538
    the problem is with shadow mapping as you can see, actually it works fine but in a certain condition that the Depth Map size must be equal to the size of rendering buffer, I use an infinite directional light so if the window is 800x600 the depth map must be 800x600, and when i change the size of the shadow map to be 900x600 it starts to be shifted and when it's size be 1024x1024 it also shifts till it disappears the GLSL shadow function float calcShadow(sampler2D Dmap, vec4 coor){ vec4 sh = vec4((coor.xyz/coor.w),1); sh.z *= 0.9; return step(sh.z,texture2D(Dmap,sh.xy).r); } here's the result when it's the same size as the window Colored result & Depth Map and here's the shifted result, as you can notice the depth map is exactly as the previous one with the addition of white space to the right.

  • Running JBoss 6 with Runit / daemontools or other process supervision framework

    - by Alex Recarey
    I'm tying to use runit to daemonize JBoss. I use the /opt/jboss-6.1.0.Final/bin/run.sh script to start the server. When I do so from the comandline, JBoss does not detach (which is what we want), and will also shut down when CTRL+C is pressed. In theory a perfect candidate to use runit on. Everything works fine except when I try to get runit to shut down JBoss. When I issue the command sv stop jboss nothing happens. Runit thinks the process is stopped but jboss continues to run normally. I'm not doing anything special with the run script. This is my runit run script: #!/bin/sh exec 2>&1 exec /opt/jboss-6.1.0.Final/bin/run.sh -c standard -b 0.0.0.0 Looking at the jboss_init_redhat.sh script, the start section does mention ./bin/run.sh but the stop section has the following text: JBOSS_CMD_STOP=${JBOSS_CMD_STOP:-"java -classpath $JBOSSCP org.jboss.Shutdown --shutdown"} Any ideas of what I could try?

  • Does query plan optimizer works well with joined/filtered table-valued functions?

    - by smoothdeveloper
    In SQLSERVER 2005, I'm using table-valued function as a convenient way to perform arbitrary aggregation on subset data from large table (passing date range or such parameters). I'm using theses inside larger queries as joined computations and I'm wondering if the query plan optimizer work well with them in every condition or if I'm better to unnest such computation in my larger queries. Does query plan optimizer unnest table-valued functions if it make sense? If it doesn't, what do you recommend to avoid code duplication that would occur by manually unnesting them? If it does, how do you identify that from the execution plan? code sample: create table dbo.customers ( [key] uniqueidentifier , constraint pk_dbo_customers primary key ([key]) ) go /* assume large amount of data */ create table dbo.point_of_sales ( [key] uniqueidentifier , customer_key uniqueidentifier , constraint pk_dbo_point_of_sales primary key ([key]) ) go create table dbo.product_ranges ( [key] uniqueidentifier , constraint pk_dbo_product_ranges primary key ([key]) ) go create table dbo.products ( [key] uniqueidentifier , product_range_key uniqueidentifier , release_date datetime , constraint pk_dbo_products primary key ([key]) , constraint fk_dbo_products_product_range_key foreign key (product_range_key) references dbo.product_ranges ([key]) ) go . /* assume large amount of data */ create table dbo.sales_history ( [key] uniqueidentifier , product_key uniqueidentifier , point_of_sale_key uniqueidentifier , accounting_date datetime , amount money , quantity int , constraint pk_dbo_sales_history primary key ([key]) , constraint fk_dbo_sales_history_product_key foreign key (product_key) references dbo.products ([key]) , constraint fk_dbo_sales_history_point_of_sale_key foreign key (point_of_sale_key) references dbo.point_of_sales ([key]) ) go create function dbo.f_sales_history_..snip.._date_range ( @accountingdatelowerbound datetime, @accountingdateupperbound datetime ) returns table as return ( select pos.customer_key , sh.product_key , sum(sh.amount) amount , sum(sh.quantity) quantity from dbo.point_of_sales pos inner join dbo.sales_history sh on sh.point_of_sale_key = pos.[key] where sh.accounting_date between @accountingdatelowerbound and @accountingdateupperbound group by pos.customer_key , sh.product_key ) go -- TODO: insert some data -- this is a table containing a selection of product ranges declare @selectedproductranges table([key] uniqueidentifier) -- this is a table containing a selection of customers declare @selectedcustomers table([key] uniqueidentifier) declare @low datetime , @up datetime -- TODO: set top query parameters . select saleshistory.customer_key , saleshistory.product_key , saleshistory.amount , saleshistory.quantity from dbo.products p inner join @selectedproductranges productrangeselection on p.product_range_key = productrangeselection.[key] inner join @selectedcustomers customerselection on 1 = 1 inner join dbo.f_sales_history_..snip.._date_range(@low, @up) saleshistory on saleshistory.product_key = p.[key] and saleshistory.customer_key = customerselection.[key] I hope the sample makes sense. Much thanks for your help!

  • How to hide items under the options from one select box upon selection of an item in another select

    - by jl
    Hi, I am new to jQuery and would like to know how is it possible for me to hide an option in a selection box based on the selection of another selection box. I have 5 selection boxes, this is for the administrator to select the users of a limited criteria. The <options> are create dynamically from the results of a database query and php, and they all have the same <options>. e.g. this is an example of the selection boxes with their option values. userbox1 - Amy, Bosh, Cathy, Daniel, Ethan userbox2 - Amy, Bosh, Cathy, Daniel, Ethan userbox3 - Amy, Bosh, Cathy, Daniel, Ethan userbox4 - Amy, Bosh, Cathy, Daniel, Ethan userbox5 - Amy, Bosh, Cathy, Daniel, Ethan So if the administrator selects Cathy in userbox1, Cathy will be automatically be hidden from the selection on the rest of the userbox. And if the administrator changes his/her mind and reselect another user call Ethan. The userboxes should be able to show the availability of Cathy in the selection. I am not sure is hide/show the correct status to be used in such cases. May I know how is it possible to write the function as stated above? If I am missing some current references, kindly point me to it. Thanks in advance.

  • Problem with RVM and gem that has an executable

    - by djhworld
    Hi there, I've recently made the plunge to use RVM on Ubuntu. Everything seems to have gone swimmingly...except for one thing. I'm in the process of developing a gem of mine that has a script placed within its own bin/ directory, all of the gemspec and things were generated by Jeweler. The bin/mygem file contains the following code: - #!/usr/bin/env ruby begin require 'mygem' rescue LoadError require 'rubygems' require 'mygem' end app = MyGem::Application.new app.run That was working fine on the system version of Ruby. Now...recently I've moved to RVM to manage my ruby versions a bit better, except now my gem doesn't appear to be working. Firstly I do this: - rvm 1.9.2 Then I do this: - rvm 1.9.2 gem install mygem Which installs fine, except...when I try to run the command for mygem mygem I just get the following exception: - daniel@daniel-VirtualBox:~$ mygem <internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- mygem (LoadError) from <internal:lib/rubygems/custom_require>:29:in `require' from /home/daniel/.rvm/gems/ruby-1.9.2-p136/gems/mygem-0.1.4/bin/mygem:2:in `<top (required)>' from /home/daniel/.rvm/gems/ruby-1.9.2-p136/bin/mygem:19:in `load' from /home/daniel/.rvm/gems/ruby-1.9.2-p136/bin/mygem:19:in `<main>'mygem NOTE: I have a similar RVM setup on MAC OSX and my gem works fine there so I think this might be something to do with Ubuntu?

  • Git on Windows 7 expecting Linux? /dev/null not found error

    - by Klikini
    I have installed git (not GitHub) on Windows 7 x64 Home Premium, and I cannot get it to work. Opening Git Bash outputs the following: Welcome to Git (version 1.9.4-preview20140815) Run 'git help git' to display the help index. Run 'get help <command>' to display help for specific commands. sh.exe": /dev/null: No such file or directory sh.exe": /dev/null: No such file or directory sh.exe": /dev/null: No such file or directory sh.exe": /dev/null: No such file or directory sh.exe": /dev/null: No such file or directory sh.exe": /dev/null: No such file or directory Andy@ANDY-DELL ~ $ If I open the Git GUI, I get a this box: Title: git-gui: fatal error Content: fatal: open /dev/null or dup failed: No such file or directory Git Gui requires Git 1.5.0 or later. I also tried GitHub for Windows, but I got an internet connection error when attempting to clone a repo, even though my connection is fine. Is this possibly related? I have learned so far that /dev/null is the Linux version of the Windows NUL, but why is it trying to do this on Windows? Thanks in advance.

  • How to use cyg-wrapper to fork a new tab in win32 gvim

    - by Peter Nore
    I would like to set up an alias in my cygwin .bashrc that translates pathnames unix-to-dos and passes them to windows gvim in a new tab of an existing instance. I am trying to use Luc Hermitte's cyg-wrapper script for running native win32 applications from Cygwin as per this vim tip. Luc's example of how to use his script is: alias vi= 'cyg-wrapper.sh "C:/Progra~1/Edition/vim/vim63/gvim.exe" --binary-opt=-c,--cmd,-T,-t,--servername,--remote-send,--remote-expr' I do not understand this example because most of these vim parameters (-c,--cmd,--servername,--remote-send,--remote-expr, etc) require more information, and I have not found any example of how to supply the additional information to cyg-wrapper.sh. For example, calling C:/Progra~1/Edition/vim/vim63/gvim.exe --servername=GVIM --remote-tab-silent file1 & will open file1 in a new tab of existing (or non existing) instance GVIM, but calling gvim --servername accomplishes nothing on its own. Unfortunately, though, the corresponding cyg-wrapper phrase does not work: cyg-wrapper.sh "C:/Progra~1/Edition/vim/vim63/gvim.exe" --binary-opt=--servername=GVIM,--remote-tab-silent --fork=2 file1 If ran twice, this actually opens up two instances of gvim; it is as if the servername 'GVIM' is being stripped and ignored. How do you supply a servername to gvim --servername or a .vimrc to gvim -u using cyg-wrapper.sh? Furthermore, why is it that programs must be passed to cyg-wrapper.sh in the relatively obscure "mixed form?" For example, if I try cyg-wrapper.sh "/cygdrive/c/path/to/GVimPortable.exe" --binary-opt=--servername=GVIM,--remote-tab-silent --fork=2 I get "Invalid switch - "/cygdrive"."
