  • A proposal for #DAX Code Formatting #ssas #powerpivot #tabular

    - by Marco Russo (SQLBI)
    I recently published a set of rules for DAX code formatting. The following is an example of what I obtain: CALCULATE (     SUMX (         Orders,         Orders[Amount]     ),     FILTER (         ALL ( Customers ),         CALCULATE (             COUNTROWS ( Sales ),             ALL ( Calendar[Date] )         ) > 42 + 8 – 25 * ( 3 - 1 )             + 2 – 1 + 2 – 1             + CALCULATE (                   2 + 2 – 2                   + 2 - 2               )             – CALCULATE ( 4 )     ) ) The goal is to improve code readability and I look forward to implement a code formatting feature in DAX Studio. The DAX Editor already supports the rules described in the article. I am also considering whether to add a rule specific for ADDCOLUMNS / SUMMARIZE because I would like to see the “pairs” of arguments to define a column in the same row or with a special indentation rule (DAX expression for a column is indented in the line following the column name). EVALUATE CALCULATETABLE (        CALCULATETABLE (         SUMMARIZE (             Audience,             'Date'[Year],             Individuals[Gender],             Individuals[AgeRange],             "Num of Rows", FORMAT (COUNTROWS (Audience), "#,#"),             "Weighted Mean Age",                 SUMX (Audience, Audience[Weight] * Audience[Age]) / SUM (Audience[Weight])         ),         SUMMARIZE (             BridgeIndividualsTargets,             Individuals[ID_Individual]         ),         Audience[Weight] > 0        ),        Targets[Target] = "Maschi",     'Date'[Year] = 2010,     'Date'[MonthName] = "January" ) I would like to get feedback for that – you can use comments here or comments in original article. Thanks!

  • Library order is important

    - by Darryl Gove
    I've written quite extensively about link ordering issues, but I've not discussed the interaction between archive libraries and shared libraries. So let's take a simple program that calls a maths library function: #include <math.h int main() { for (int i=0; i<10000000; i++) { sin(i); } } We compile and run it to get the following performance: bash-3.2$ cc -g -O fp.c -lm bash-3.2$ timex ./a.out real 6.06 user 6.04 sys 0.01 Now most people will have heard of the optimised maths library which is added by the flag -xlibmopt. This contains optimised versions of key mathematical functions, in this instance, using the library doubles performance: bash-3.2$ cc -g -O -xlibmopt fp.c -lm bash-3.2$ timex ./a.out real 2.70 user 2.69 sys 0.00 The optimised maths library is provided as an archive library (libmopt.a), and the driver adds it to the link line just before the maths library - this causes the linker to pick the definitions provided by the static library in preference to those provided by libm. We can see the processing by asking the compiler to print out the link line: bash-3.2$ cc -### -g -O -xlibmopt fp.c -lm /usr/ccs/bin/ld ... fp.o -lmopt -lm -o a.out... The flag to the linker is -lmopt, and this is placed before the -lm flag. So what happens when the -lm flag is in the wrong place on the command line: bash-3.2$ cc -g -O -xlibmopt -lm fp.c bash-3.2$ timex ./a.out real 6.02 user 6.01 sys 0.01 If the -lm flag is before the source file (or object file for that matter), we get the slower performance from the system maths library. Why's that? If we look at the link line we can see the following ordering: /usr/ccs/bin/ld ... -lmopt -lm fp.o -o a.out So the optimised maths library is still placed before the system maths library, but the object file is placed afterwards. This would be ok if the optimised maths library were a shared library, but it is not - instead it's an archive library, and archive library processing is different - as described in the linker and library guide: "The link-editor searches an archive only to resolve undefined or tentative external references that have previously been encountered." An archive library can only be used resolve symbols that are outstanding at that point in the link processing. When fp.o is placed before the libmopt.a archive library, then the linker has an unresolved symbol defined in fp.o, and it will search the archive library to resolve that symbol. If the archive library is placed before fp.o then there are no unresolved symbols at that point, and so the linker doesn't need to use the archive library. This is why libmopt needs to be placed after the object files on the link line. On the other hand if the linker has observed any shared libraries, then at any point these are checked for any unresolved symbols. The consequence of this is that once the linker "sees" libm it will resolve any symbols it can to that library, and it will not check the archive library to resolve them. This is why libmopt needs to be placed before libm on the link line. This leads to the following order for placing files on the link line: Object files Archive libraries Shared libraries If you use this order, then things will consistently get resolved to the archive libraries rather than to the shared libaries.

  • Essbase BSO Data Fragmentation

    - by Ann Donahue
    Essbase BSO Data Fragmentation Data fragmentation naturally occurs in Essbase Block Storage (BSO) databases where there are a lot of end user data updates, incremental data loads, many lock and send, and/or many calculations executed.  If an Essbase database starts to experience performance slow-downs, this is an indication that there may be too much fragmentation.  See Chapter 54 Improving Essbase Performance in the Essbase DBA Guide for more details on measuring and eliminating fragmentation: http://docs.oracle.com/cd/E17236_01/epm.1112/esb_dbag/daprcset.html Fragmentation is likely to occur in the following situations: Read/write databases that users are constantly updating data Databases that execute calculations around the clock Databases that frequently update and recalculate dense members Data loads that are poorly designed Databases that contain a significant number of Dynamic Calc and Store members Databases that use an isolation level of uncommitted access with commit block set to zero There are two types of data block fragmentation Free space tracking, which is measured using the Average Fragmentation Quotient statistic. Block order on disk, which is measured using the Average Cluster Ratio statistic. Average Fragmentation Quotient The Average Fragmentation Quotient ratio measures free space in a given database.  As you update and calculate data, empty spaces occur when a block can no longer fit in its original space and will either append at the end of the file or fit in another empty space that is large enough.  These empty spaces take up space in the .PAG files.  The higher the number the more empty spaces you have, therefore, the bigger the .PAG file and the longer it takes to traverse through the .PAG file to get to a particular record.  An Average Fragmentation Quotient value of 3.174765 means the database is 3% fragmented with free space. Average Cluster Ratio Average Cluster Ratio describes the order the blocks actually exist in the database. An Average Cluster Ratio number of 1 means all the blocks are ordered in the correct sequence in the order of the Outline.  As you load data and calculate data blocks, the sequence can start to be out of order.  This is because when you write to a block it may not be able to place back in the exact same spot in the database that it existed before.  The lower this number the more out of order it becomes and the more it affects performance.  An Average Cluster Ratio value of 1 means no fragmentation.  Any value lower than 1 i.e. 0.01032828 means the data blocks are getting further out of order from the outline order. Eliminating Data Block Fragmentation Both types of data block fragmentation can be removed by doing a dense restructure or export/clear/import of the data.  There are two types of dense restructure: 1. Implicit Restructures Implicit dense restructure happens when outline changes are done using EAS Outline Editor or Dimension Build. Essbase restructures create new .PAG files restructuring the data blocks in the .PAG files. When Essbase restructures the data blocks, it regenerates the index automatically so that index entries point to the new data blocks. Empty blocks are NOT removed with implicit restructures. 2. Explicit Restructures Explicit dense restructure happens when a manual initiation of the database restructure is executed. An explicit dense restructure is a full restructure which comprises of a dense restructure as outlined above plus the removal of empty blocks Empty Blocks vs. Fragmentation The existence of empty blocks is not considered fragmentation.  Empty blocks can be created through calc scripts or formulas.  An empty block will add to an existing database block count and will be included in the block counts of the database properties.  There are no statistics for empty blocks.  The only way to determine if empty blocks exist in an Essbase database is to record your current block count, export the entire database, clear the database then import the exported data.  If the block count decreased, the difference is the number of empty blocks that had existed in the database.

  • Any tips on getting hired as a software project manager straight out of college?

    - by MHarrison
    I graduated with a BS in compsci last September, and I've been trying (unsuccessfully) to find a job as a project manager ever since. I fell in love with software engineering (the formal practice behind it all, not just coding) in school, and I've dedicated the last 3-4 years of my life to learning everything I can about project management and gaining experience. I've managed several projects (with teams around 12 people) while in school, and I worked with my university's software engineering research lab. My résumé is also decent - I worked as a programmer before I went to school (I'm 27 now), and I did Google Summer of Code for 3 summers. I also have general "people management" experience via working as the photo editor for my university's newspaper for 2 years. My first problem with the job hunt is not getting enough interviews. I use careers.stackoverflow.com, which is awesome because I usually get contacted by non-HR people who know what they're talking about, but there's just not enough companies using it for me to get interviews on a regular basis. I've also tried sites like monster.com, and in a fit of desperation, I sent out no less than 60 applications to project management positions. I've gotten 3 automated rejection letters and that's it. At least careers.stackoverflow gets me a phone interview with 8/10 places I apply to. But the main (and extremely frustrating) problem is the matter of experience. I've successfully managed projects from start to finish (in my software engineering classes we had real customers come in with a real software need and we built it for them), but I've never had to deal with budgets and money (I know this is why HR people immediately turn me away). Most of these positions require 5+ years PM experience, and I've seen absurd things like 12+ years required. Interviews are also maddening. I've had so many places who absolutely loved me and I made it to the final round of interviews, and I left thinking things went extremely well and they'd consider me. However, when I check in with them a week later, they tell me "We really liked you and your qualifications are excellent, but we're hoping to find someone with more experience." The bad interviews I can understand - like the PM position that would have had me managing developers both locally and overseas - I had 3 interviews with them and the ENTIRE interview process was them asking me CS brainteasers and having me waste time on things like writing quicksort on paper or writing binary search trees. Even when I tried steering the discussion towards more relevant PM stuff, they gave me some vague generic replies and went back to the "We want to be Google/MS" crap. But when I have a GOOD interview, they say my "qualifications are excellent" but they want "more experience"...that makes me want to tear my hair out. What else can I DO? While I'm aiming for technically-involved PM positions (not just crunching budget numbers), I really don't want a straight development job because I like creating software from the very high-level vs. spending a lot of time debugging memory leaks. In fact, I can't even GET development positions that I'm qualified for because I make the mistake of telling them that my future career goals are as PM (which usually results in them saying something like "Well we already have PMs and this position isn't really set up to get you there." - which I take to mean "No, that's my job, stay away.") My apologies on the long rant, but I'm seriously hellbent on getting hired as a PM since it's both my career goal and the passion that keeps me awake at night. Any suggestions on what the heck else I can do? I'm currently writing a blog where I talk about my philosophies about software engineering, and I'm writing up specs for an iOS app which I will design, code, and show employers, but this takes an awful lot of time that I don't have.

  • Running Powershell from within SharePoint

    - by Norgean
    Just because something is a daft idea, doesn't mean it can't be done. We sometimes need to do some housekeeping - like delete old files or list items or… yes, well, whatever you use Powershell for in a SharePoint world. Or it could be that your solution has "issues" for which you have Powershell solutions, but not the budget to transform into proper bug fixes. So you create a "how to" for the ITPro guys. Idea: What if we keep the scripts in a list, and have SharePoint execute the scripts on demand? An announcements list (because of the multiline body field). Warning! Let us be clear. This list needs to be locked down; if somebody creates a malicious script and you run it, I cannot help you. First; we need to figure out how to start Powershell scripts from C#. Hit teh interwebs and the Googlie, and you may find jpmik's post: http://www.codeproject.com/Articles/18229/How-to-run-PowerShell-scripts-from-C. (Or MS' official answer at http://msdn.microsoft.com/en-us/library/ee706563(v=vs.85).aspx) public string RunPowershell(string powershellText, SPWeb web, string param1, string param2) { // Powershell ~= RunspaceFactory - i.e. Create a powershell context var runspace = RunspaceFactory.CreateRunspace(); var resultString = new StringBuilder(); try { // load the SharePoint snapin - Note: you cannot do this in the script itself (i.e. add-pssnapin etc does not work) PSSnapInException snapInError; runspace.RunspaceConfiguration.AddPSSnapIn("Microsoft.SharePoint.PowerShell", out snapInError); runspace.Open(); // set a web variable. runspace.SessionStateProxy.SetVariable("webContext", web); // and some user defined parameters runspace.SessionStateProxy.SetVariable("param1", param1); runspace.SessionStateProxy.SetVariable("param2", param2); var pipeline = runspace.CreatePipeline(); pipeline.Commands.AddScript(powershellText); // add a "return" variable pipeline.Commands.Add("Out-String"); // execute! var results = pipeline.Invoke(); // convert the script result into a single string foreach (PSObject obj in results) { resultString.AppendLine(obj.ToString()); } } finally { // close the runspace runspace.Close(); } // consider logging the result. Or something. return resultString.ToString(); } Ok. We've written some code. Let us test it. var runner = new PowershellRunner(); runner.RunPowershellScript(@" $web = Get-SPWeb 'http://server/web' # or $webContext $web.Title = $param1 $web.Update() $web.Dispose() ", null, "New title", "not used"); Next step: Connect the code to the list, or more specifically, have the code execute on one (or several) list items. As there are more options than readers, I'll leave this as an exercise for the reader. Some alternatives: Create a ribbon button that calls RunPowershell with the body of the selected itemsAdd a layout pageSpecify list item from query string (possibly coupled with content editor webpart with html that links directly to this page with querystring)WebpartListing with an "execute" columnList with multiselect and an execute button Etc!Now that you have the code for executing powershell scripts, you can easily expand this into a timer job, which executes scripts at regular intervals. But if the previous solution was dangerous, this is even worse - the scripts will usually be run with one of the admin accounts, and can do pretty much anything...One more thing... Note that as this is running "consoleless" calls to Write-Host will fail. Two solutions; remove all output, or check if the script is run in a console-window or not.  if ($host.Name -eq "ConsoleHost") { Write-Host 'If I agreed with you we'd both be wrong' }

However, device formats are so varied that delivering a mobile web experience that will engage site visitors and enhance your brand can be a daunting task. Solutions that empower organizations to easily extend their web presence to the mobile channel, while saving significant time and effort in managing mobile sites, are now essential in our ever connected mobile world. So what are some of the things organizations should look for in such a solution? Mobile device form factors, networks, protocols, and browsers vary widely, and reformatting web content for thousands of different device and software combinations is a prohibitive task. An effective mobile solution can make this process seamless by automatically formatting designated web content for mobile delivery.  By automatically detecting a site visitor’s device configuration, the selected web content can be sized and formatted for optimal display on that particular device. This can save tremendous time involved in building, formatting, and maintaining individual websites or mobile applications for different mobile devices. It’s not enough to simply support the thousands of different mobile device types that are out there. It’s also critical to make it easy for marketers and other business users to manage mobile sites and mobile content. Those responsible for maintaining an organization’s web and mobile experiences need the ability to edit content using rich text editor tools and then preview that content directly in the context of the mobile website and the traditional website, ideally from the same business user interface. Powerful capabilities such as these make managing the web experience for mobile devices easy, even with frequently changing content, across a multitude of different devices. This saves tremendous time involved in building, formatting, and maintaining individual websites or mobile applications for different mobile devices. When content or business needs change, the business user needs only to change site content once, and it is seamlessly deployed to the web and all mobile channels.Geo-location is another critical input to making the online experience engaging and relevant for web visitors who are increasingly mobile. A mobile solution should enable use of device GPS data to deliver location-based content and services to mobile website visitors. Organizations can provide mobile site visitors with location-sensitive search results, location-based offers and recommendations, integration of maps and directions into site content, and much more – all critical for meeting the needs of those on the go.To hear more about how mobile is changing the game, check out our recent webcast with Ted Schadler, Vice President, Principal Analyst, Forrester, where he discussed why mobile is the new face of engagement, or learn more about how to extend your web presence to the mobile channel with Oracle WebCenter Sites and Oracle WebCenter Sites Mobility Server.

  • Looking into CSS3 Multiple backgrounds

    - by nikolaosk
    In this post I will be looking into a great feature in CSS3 called multiple backgrounds.With CSS3 ourselves as web designers we can specify multiple background images for box elements, using nothing more than a simple comma-separated list. This is a very nice feature that can be useful in many websites.In this hands-on example I will be using Expression Web 4.0.This application is not a free application. You can use any HTML editor you like.You can use Visual Studio 2012 Express edition. You can download it here.Before I go on with the actual demo I will use the (http://www.caniuse.com) to see the support for CSS 3 Multiple backgrounds from the latest versions of modern browsers.Please have a look in this link All modern browsers support this feature. I am typing this very simple HTML 5 markup with an internal CSS style.<!DOCTYPE html><html lang="en">  <head>    <title>Sold items</title>        <style>                #box{        border:1px solid #afafaf;        width:260px;        height:290px;        background-image:url(shirt.png), url(sold.jpg);        background-position: center bottom, right top;        background-repeat: no-repeat, no-repeat;    </style>    </head>  <body>    <header>                <h1>CSS3 Multiple backgrounds</h1>    </header>           <div id="box">              </div>        <footer>        <p>All Rights Reserved</p>      </footer>     </body>  </html>  Let me explain what I do here, multiple background images are specified using a comma-separated list of values for the background-image property.A comma separated list is also used for the other background properties such as background-repeat, background-position .So in the next three lines of CSS code         background-image:url(shirt.png), url(sold.jpg);        background-position: center bottom, right top;        background-repeat: no-repeat, no-repeat; we have 2 images placed in the div element. The first is placed center bottom in the div element and the second is placed at right top position inside the div element.Both images do not get repeated.I view the page in IE 10 and all the latest versions of Opera,Chrome and Firefox.Have a look at the picture below. Hope it helps!!!!

  • Dual monitor not working completely in 12.10 after upgrade

    - by Mark Baldridge
    At 12.04, dual monitors worked perfectly. After upgrading to 12.10, the primary monitor works, the second monitor only partly works. I am sure there is some difference between the releases that I have missed setting properly. System settings - Displays show both correctly as Acer 22" monitors at 1680x1050 (16:10). An icon on monitor 2 is present, but elongated; almost an artifact, since other icons on the primary screen are absent, but this one icon is there on th second monitor. Selecting the icons on both screens exist. Painting is weird on monitor 2. Launcher exists and works on both screens, but even with sticky edges off, the cursor stops at the left edge of monitor 2. Clicking on text editor on screen 2 launcer will launch gedit there. If I drag it, it leaves a trail of after images like repaint is failing. If I drive the cursor on the launcher, the help tags like "LibreOffice Writer" appear, but stay on screen unless I drag the active gedit window over them. Then part of the help bubbles are overwritten, leaving behind after images of the gedit window on screen. What is really fascinating is that the System settings - Displays is now ignoring monitor selection, after allowing it earlier. Just before this, the help popup which said "Select a monitor to change its properties; drag to rearrange its placement" actually let me do that. Maybe a trick of where I grab the edge of the monitor in the Displays setting. I just found a working handle. When I drag monitor 1 to the right of monitor 2, "Apply" and confirm, both monitors work normally (although the right monitor lets the cursor slide off the right edge onto the left edge of monitor 1 - which sounds correct). Painting of windows does not leave an after image. However, success is only temporary. The setting survives the reboot, but painting on the left monitor, now monitor 2, now replicates the issues from before. The after image of the gedit window and the small window for "Are you sure you want to close all programs and restart the computer?" are still on monitor 2 (on the left now), even though they are not real windows, nor do they have processes behind them. Curiously, in Displays, the "green" monitor on the left in the display window is matched by the right monitor color in the monitor upper left corner. Probably makes sense as the one on the right is now monitor 1. If I repeat the "drag the left monitor to the right of the right monitor on the "Displays" window, things are oriented properly, with no display artifacts as I drag windows around either screen. Also the description bubbles that pop up are overwritten on both screens, so none of those artifacts either. This goodness does not survive a reboot, however. Have not tried logging out and back in. All of this after positing that the motherboard VGA and HDMI ports could have been the issue. So, I installed an e-GeForce 7600 GT Dual DVI (I know the web thinks it is not DVI, but VGA, but the connectors are DVI). No change to the weird behavior. The good parts continue to work, the weirdness also works, and swapping monitor positions seems to cure the issue. So, is there a setting I have missed? Given "swapping" monitor 1 and 2 on the System Settings... - Displays makes it work, just not across boot, I suspect so.

  • MySQL Connector/Net 6.6.2 has been released

    - by fernando
    MySQL Connector/Net 6.6.2, a new version of the all-managed .NET driver for MySQL has been released.  This is the first of two beta releases intended to introduce users to the new features in the release.  This release is feature complete it should be stable enough for users to understand the new features and how we expect them to work.  As is the case with all non-GA releases, it should not be used in any production environment.  It is appropriate for use with MySQL server versions 5.0-5.6 It is now available in source and binary form from http://dev.mysql.com/downloads/connector/net/#downloads and mirror sites (note that not all mirror sites may be up to date at this point-if you can't find this version on some mirror, please try again later or choose another download site.) The 6.6 version of MySQL Connector/Net brings the following new features:   * Stored routine debugging   * Entity Framework 4.3 Code First support   * Pluggable authentication (now third parties can plug new authentications mechanisms into the driver).   * Full Visual Studio 2012 support: everything from Server Explorer to Intellisense & the Stored Routine debugger. Stored Procedure Debugging ------------------------------------------- We are very excited to introduce stored procedure debugging into our Visual Studio integration.  It works in a very intuitive manner by simply clicking 'Debug Routine' from Server Explorer. You can debug stored routines, functions & triggers. Some of the new features in this release include:   * Besides normal breakpoints, you can define conditional & pass count breakpoints.   * Now the debugger editor shows colorizing.   * Now you can change the values of locals in a function scope (previously caused deadlock due to functions executing within their own transaction).   * Now you can also debug triggers for 'replace' sql statements.   * In general anything related to locals, watches, breakpoints, stepping & call stack should work in a similar way to the C#'s Visual Studio debugger. Some limitations remains, due to the current debugger architecture:   * Some MySQL functions cannot be debugged currently (get_lock, release_lock, begin, commit, rollback, set transaction level)..   * Only one debug session may be active on a given server. The Debugger is feature complete at this point. We look forward to your feedback. Documentation ------------------------------------- The documentation is still being developed and will be readily available soon (before Beta 2).  You can view current Connector/Net documentation at http://dev.mysql.com/doc/refman/5.5/en/connector-net.html You can find our team blog at http://blogs.oracle.com/MySQLOnWindows. You can also post questions on our forums at http://forums.mysql.com/. Enjoy and thanks for the support!

  • Using Private Extension Galleries in Visual Studio 2012

    - by Jakob Ehn
    Note: The installer and the complete source code is available over at CodePlex at the following location: http://inmetavsgallery.codeplex.com   Extensions and addins are everywhere in the Visual Studio ALM ecosystem! Microsoft releases new cool features in the form of extensions and the list of 3rd party extensions that plug into Visual Studio just keeps growing. One of the nice things about the VSIX extensions is how they are deployed. Microsoft hosts a public Visual Studio Gallery where you can upload extensions and make them available to the rest of the community. Visual Studio checks for updates to the installed extensions when you start Visual Studio, and installing/updating the extensions is fast since it is only a matter of extracting the files within the VSIX package to the local extension folder. But for custom, enterprise-specific extensions, you don’t want to publish them online to the whole world, but you still want an easy way to distribute them to your developers and partners. This is where Private Extension Galleries come into play. In Visual Studio 2012, it is now possible to add custom extensions galleries that can point to any URL, as long as that URL returns the expected content of course (see below).Registering a new gallery in Visual Studio is easy, but there is very little documentation on how to actually host the gallery. Visual Studio galleries uses Atom Feed XML as the protocol for delivering new and updated versions of the extensions. This MSDN page describes how to create a static XML file that returns the information about your extensions. This approach works, but require manual updates of that file every time you want to deploy an update of the extension. Wouldn’t it be nice with a web service that takes care of this for you, that just lets you drop a new version of your VSIX file and have it automatically detect the new version and produce the correct Atom Feed XML? Well search no more, this is exactly what the Inmeta Visual Studio Gallery Service does for you :-) Here you can see that in addition to the standard Online galleries there is an Inmeta Gallery that contains two extensions (our WIX templates and our custom TFS Checkin Policies). These can be installed/updated i the same way as extensions from the public Visual Studio Gallery. Installing the Service Download the installler (Inmeta.VSGalleryService.Install.msi) for the service and run it. The installation is straight forward, just select web site, application pool and (optional) a virtual directory where you want to install the service.   Note: If you want to run it in the web site root, just leave the application name blank Press Next and finish the installer. Open web.config in a text editor and locate the the <applicationSettings> element Edit the following setting values: FeedTitle This is the name that is shown if you browse to the service using a browser. Not used by Visual Studio BaseURI When Visual Studio downloads the extension, it will be given this URI + the name of the extension that you selected. This value should be on the following format: http://SERVER/[VDIR]/gallery/extension/ VSIXAbsolutePath This is the path where you will deploy your extensions. This can be a local folder or a remote share. You just need to make sure that the application pool identity account has read permissions in this folder Save web.config to finish the installation Open a browser and enter the URL to the service. It should show an empty Feed page:   Adding the Private Gallery in Visual Studio 2012 Now you need to add the gallery in Visual Studio. This is very easy and is done as follows: Go to Tools –> Options and select Environment –> Extensions and Updates Press Add to add a new gallery Enter a descriptive name, and add the URL that points to the web site/virtual directory where you installed the service in the previous step   Press OK to save the settings. Deploying an Extension This one is easy: Just drop the file in the designated folder! :-)  If it is a new version of an existing extension, the developers will be notified in the same way as for extensions from the public Visual Studio gallery: I hope that you will find this sever useful, please contact me if you have questions or suggestions for improvements!

  • Criminals and Other Illegal Characters

    - by Most Valuable Yak (Rob Volk)
    SQLTeam's favorite Slovenian blogger Mladen (b | t) had an interesting question on Twitter: http://www.twitter.com/MladenPrajdic/status/347057950470307841 I liked Kendal Van Dyke's (b | t) reply: http://twitter.com/SQLDBA/status/347058908801667072 And he was right!  This is one of those pretty-useless-but-sounds-interesting propositions that I've based all my presentations on, and most of my blog posts. If you read all the replies you'll see a lot of good suggestions.  I particularly like Aaron Bertrand's (b | t) idea of going into the Unicode character set, since there are over 65,000 characters available.  But how to find an illegal character?  Detective work? I'm working on the premise that if SQL Server will reject it as a name it would throw an error.  So all we have to do is generate all Unicode characters, rename a database with that character, and catch any errors. It turns out that dynamic SQL can lend a hand here: IF DB_ID(N'a') IS NULL CREATE DATABASE [a]; DECLARE @c INT=1, @sql NVARCHAR(MAX)=N'', @err NVARCHAR(MAX)=N''; WHILE @c<65536 BEGIN BEGIN TRY SET @sql=N'alter database ' + QUOTENAME(CASE WHEN @c=1 THEN N'a' ELSE NCHAR(@c-1) END) + N' modify name=' + QUOTENAME(NCHAR(@c)); RAISERROR(N'*** Trying %d',10,1,@c) WITH NOWAIT; EXEC(@sql); SET @c+=1; END TRY BEGIN CATCH SET @err=ERROR_MESSAGE(); RAISERROR(N'Ooops - %d - %s',10,1,@c,@err) WITH NOWAIT; BREAK; END CATCH END SET @sql=N'alter database ' + QUOTENAME(NCHAR(@c-1)) + N' modify name=[a]'; EXEC(@sql); The script creates a dummy database "a" if it doesn't already exist, and only tests single characters as a database name.  If you have databases with single character names then you shouldn't run this on that server. It takes a few minutes to run, but if you do you'll see that no errors are thrown for any of the characters.  It seems that SQL Server will accept any character, no matter where they're from.  (Well, there's one, but I won't tell you which. Actually there's 2, but one of them requires some deep existential thinking.) The output is also interesting, as quite a few codes do some weird things there.  I'm pretty sure it's due to the font used in SSMS for the messages output window, not all characters are available.  If you run it using the SQLCMD utility, and use the -o switch to output to a file, and -u for Unicode output, you can open the file in Notepad or another text editor and see the whole thing. I'm not sure what character I'd recommend to answer Mladen's question.  I think the standard tab (ASCII 9) is fine.  There's also several specific separator characters in the original ASCII character set (decimal 28-31). But of all the choices available in Unicode whitespace, I think my favorite would be the Mongolian Vowel Separator.  Or maybe the zero-width space. (that'll be fun to print!)  And since this is Mladen we're talking about, here's a good selection of "intriguing" characters he could use.

  • Editing files without race conditions?

    - by user2569445
    I have a CSV file that needs to be edited by multiple processes at the same time. My question is, how can I do this without introducing race conditions? It's easy to write to the end of the file without race conditions by open(2)ing it in "a" (O_APPEND) mode and simply write to it. Things get more difficult when removing lines from the file. The easiest solution is to read the file into memory, make changes to it, and overwrite it back to the file. If another process writes to it after it is in memory, however, that new data will be lost upon overwriting. To further complicate matters, my platform does not support POSIX record locks, checking for file existence is a race condition waiting to happen, rename(2) replaces the destination file if it exists instead of failing, and editing files in-place leaves empty bytes in it unless the remaining bytes are shifted towards the beginning of the file. My idea for removing a line is this (in pseudocode): filename = "/home/user/somefile"; file = open(filename, "r"); tmp = open(filename+".tmp", "ax") || die("could not create tmp file"); //"a" is O_APPEND, "x" is O_EXCL|O_CREAT while(write(tmp, read(file)); //copy the $file to $file+".new" close(file); //edit tmp file unlink(filename) || die("could not unlink file"); file = open(filename, "wx") || die("another process must have written to the file after we copied it."); //"w" is overwrite, "x" is force file creation while(write(file, read(tmp))); //copy ".tmp" back to the original file unlink(filename+".tmp") || die("could not unlink tmp file"); Or would I be better off with a simple lock file? Appender process: lock = open(filename+".lock", "wx") || die("could not lock file"); file = open(filename, "a"); write(file, "stuff"); close(file); close(lock); unlink(filename+".lock"); Editor process: lock = open(filename+".lock", "wx") || die("could not lock file"); file = open(filename, "rw"); while(contents += read(file)); //edit "contents" write(file, contents); close(file); close(lock); unlink(filename+".lock"); Both of these rely on an additional file that will be left over if a process terminates before unlinking it, causing other processes to refuse to write to the original file. In my opinion, these problems are brought on by the fact that the OS allows multiple writable file descriptors to be opened on the same file at the same time, instead of failing if a writable file descriptor is already open. It seems that O_CREAT|O_EXCL is the closest thing to a real solution for preventing filesystem race conditions, aside from POSIX record locks. Another possible solution is to separate the file into multiple files and directories, so that more granular control can be gained over components (lines, fields) of the file using O_CREAT|O_EXCL. For example, "file/$id/$field" would contain the value of column $field of the line $id. It wouldn't be a CSV file anymore, but it might just work. Yes, I know I should be using a database for this as databases are built to handle these types of problems, but the program is relatively simple and I was hoping to avoid the overhead. So, would any of these patterns work? Is there a better way? Any insight into these kinds of problems would be appreciated.

  • Disabling the right-click sub menu using JQuery

    - by nikolaosk
    Recently I needed to disable the right-click contextual menu in an HTML page for a very simple HTML application I was creating for a friend.This is going to be a short post where I will demonstrate how to disable the right-click contextual menu.I will use the very popular JQuery Library. Please download the library (minified version) from http://jquery.com/downloadPlease find here all my posts regarding JQuery.In this hands-on example I will be using Expression Web 4.0.This application is not a free application. You can use any HTML editor you like.You can use Visual Studio 2012 Express edition. You can download it here. I am going to create a very simple HTML 5 page with some text and an image. The HTML markup for the page follows. <!DOCTYPE html><html lang="en">  <head>    <title>HTML 5, CSS3 and JQuery</title>        <meta http-equiv="Content-Type" content="text/html;charset=utf-8" >    <link rel="stylesheet" type="text/css" href="style.css">     <script type="text/javascript" src="jquery-1.8.2.min.js">        </script><script type="text/javascript"> (function ($) { $(document).bind('contextmenu', function () { return false;}); })(jQuery); </script>       </head>  <body>      <div id="header">      <h1>Learn cutting edge technologies</h1>      <h2>HTML 5, JQuery, CSS3</h2>    </div>      <figure>  <img src="html5.png" alt="HTML 5"></figure>        <div id="main">          <h2>HTML 5</h2>                        <article>          <p>            HTML5 is the latest version of HTML and XHTML. The HTML standard defines a single language that can be written in HTML and XML. It attempts to solve issues found in previous iterations of HTML and addresses the needs of Web Applications, an area previously not adequately covered by HTML.          </p>          </article>      </div>             </body>  </html> This is the JQuery code, I use (function ($) { $(document).bind('contextmenu', function () { return false;}); })(jQuery); I simply disable/cancel the contextmenu event.When I load the simple page on the browser and I right-click the context menu does not appear.Hope it helps!!!

  • Avoid richfaces to send back javascript libraries in the ajax responses

    - by pakore
    I'm using JSF 1.2 with Richfaces, and for every ajax request, the server is sending back the response, whichi is good, but it also contains all the links to the javascript files. I want to improve the performance so I just want the <body> to be returned, because all the javascript files are already loaded in the browser when the user logs in (my app is not restful). How can i do that?

  • EXT-js PropertyGrid best practices to achieve an update ?

    - by Tom
    Hello, I am using EXT-js for a project, usually everything is pretty straight forward with EXT-js, but with the propertyGrid, I am not sure. I'd like some advice about this piece of code. First the store to populate the property grid, on the load event: var configStore = new Ext.data.JsonStore({ // store config autoLoad:true, url: url.remote, baseParams : {xaction : 'read'}, storeId: 'configStore', // reader config idProperty: 'id_config', root: 'config', totalProperty: 'totalcount', fields: [{ name: 'id_config' }, { name: 'email_admin' } , { name: 'default_from_addr' } , { name: 'default_from_name' } , { name: 'default_smtp' } ],listeners: { load: { fn: function(store, records, options){ // get the property grid component var propGrid = Ext.getCmp('propGrid'); // make sure the property grid exists if (propGrid) { // populate the property grid with store data propGrid.setSource(store.getAt(0).data); } } } } }); here is the propertyGrid: var propsGrid = new Ext.grid.PropertyGrid({ renderTo: 'prop-grid', id: 'propGrid', width: 462, autoHeight: true, propertyNames: { tested: 'QA', borderWidth: 'Border Width' }, viewConfig : { forceFit: true, scrollOffset: 2 // the grid will never have scrollbars } }); So far so good, but with the next button, I'll trigger an old school update, and my question : Is that the proper way to update this component ? Or is it better to user an editor ? or something else... for regular grid I use the store methods to do the update, delete,etc... The examples are really scarce on this one! Even in books about ext-js! new Ext.Button({ renderTo: 'button-container', text: 'Update', handler: function(){ var grid = Ext.getCmp("propGrid"); var source = grid.getSource(); var jsonDataStr = null; jsonDataStr = Ext.encode(source); var requestCg = { url : url.update, method : 'post', params : { config : jsonDataStr , xaction : 'update' }, timeout : 120000, callback : function(options, success, response) { alert(success + "\t" + response); } }; Ext.Ajax.request(requestCg); } }); and thanks for reading.

  • Sharepoint - Passing parameters in URL to NewForm.aspx

    - by kevin
    Any suggestions would be great. I've inherited a system and have been requested to add a context menu item to allow the ability to add a new item. I've set up the context menu with the new option and the newform.aspx to accept and pull parameters from the url for populating some fields. The context menu was created with the content editor web part and the follow JavaScript. function Custom_AddDocLibMenuItems(m, ctx) { var strAction = "window.location='http://address?para1=....'"; var strDisplayText = "Taxonomy"; var strImagePath = ""; // Add our new menu item CAMOpt(m, strDisplayText, strAction, strImagePath); // add a separator to the menu CAMSep(m); // false means that the standard menu items should also be rendered return false; } I'm having difficulties getting the proper values in order to concatenate them to the strAction string (which would be the full url of the newform.aspx. Any suggestions on how I retrieve the values of the columns for the item that the user right click to get context menu.

  • ExtJS: Combobox in EditorGridPanel not selecting the desired item (with test case)

    - by TomH
    I'm using ExtJS to create an EditorGridPanel with a combobox for an editor in a cell. The combobox in my EditorGridPanel that is not working as I'd expect it to. When the user types the first letter of an item in the drop down list, the combobox seems to ignore it and select the first item in the list. I can reproduce the error consistently and have put together a test case here: http://cluebucket.com/dev/testcase/testcase.html Load the page and reproduce the behavior by the following -- note that this is all done using the keyboard, no mouse clicks: Click 'Add Record' (A new row is added to the grid) enter text in the text field. TAB to the Priority field without selecting anything (None will remain selected) TAB out of the Priority field. (A new row is added to the grid) enter text and TAB to the Priority field TYPE v (Very High is selected) TAB out of the priority field (A new row is added to the grid) enter text and TAB to the Priority field Type v (None is selected, but Very High should have been) TAB out of the priority field Enter text and TAB to the priority field Type l ('el') (Low is selected) TAB out, enter text, TAB to priority Type l (None is selected) It appears that whenever the user attempts to select the same value that was selected in the previous row, the combobox selects None. Any ideas? The code is available at cluebucket.com/dev/testcase/js/testcase.js Thoughts/Pointers/Corrections are appreciated!! thanks tom

  • Hidden Features of C#?

    This came to my mind after I learned the following from this question: where T : struct We, C# developers, all know the basics of C#. I mean declarations, conditionals, loops, operators, etc. Some of us even mastered the stuff like Generics, anonymous types, lambdas, linq, ...

  • Using QTDesigner with PyQT and Python 2.6

    - by PyNewbie27
    Hi. I'm fairly new to Python and trying to work with the latest versions of QTDesigner, PyQT 4.7 and QT4.7 (I downloaded the whole package from PyQT4.7 website). I can't figure out how to make QTDesigner integrate closely with Python: ie. If I select "Form" View Code in QTDesigners menu, it errors saying "Unable to launch C:/Python26/Lib/site-packages/PyQT4/bin\uic." If I look in that directory there is a pyuic.py but not "uic". From searching online it seems this doesn't exist because it's expecting a C++ install instead of the python version. Is there anyway to make QTDesigner use/call pyuic.py to generate the code, then open an IDE or text editor of my choice to show me the PYTHON code generated by the QTDesigner-PyUIC chain? I'd like Designer to integrate closely with python, so I can make custom slots/signals in Designer while designing, then tweak the python code directly in my IDE later. If it is not possible to code directly inside QTDesigner using python, does that mean I have to hand code my programs entire UI directly in my PythonIDE? Using Designer directly would seemingly be nearly very very nice for a newbie such as myself, since I can see what properties each widget has and visually edit them while still learning the QT syntax without constantly having to use web resources to see what properties each widget should have and helps with boilerplate code generation, and what their defaults are, etc. I've googled and nobody seems to be using QTDesigner and Python in this manner together. It seems most are either handcoding all the QT code in their Python IDE of choice, or have found an obvious/easy method of doing what I want, therefore not really producing up to date tutorials on making this work together. Please enlighten me if you can. Thanks in advance for your time. Please include any suggestions you might have to a newbie trying to use Python with QT and QTDesigner. Thank you.

  • Calling Matlab's MLApp.MLAppClass.FEval from F#

    - by Matthew
    Matlab provides a COM interface that supports remote execution of arbitrary functions (and code snippets). In particular, it has an Feval method that calls a given Matlab function. The third parameter to this method, pvarArgOut, has COM type VARIANT*, and appears in the Visual Studio F# editor as an argument of type: pvarArgOut: byref<obj> The following code calls interp1, which in Matlab returns a matrix (i.e. 2D double array) result, as is normal for most Matlab functions. let matlab = new MLApp.MLAppClass() let vector_to_array2d (v : vector) = Array2D.init v.Length 1 (fun i j -> v.[i]) let interp1 (xs : vector) (ys : vector) (xi : vector) = let yi : obj = new obj() matlab.Feval("interp1", 1, ref yi, vector_to_array2d xs, vector_to_array2d ys, vector_to_array2d xi) yi :?> float[,] This code compiles fine, but when calling interp1, I get a COM exception: A first chance exception of type 'System.Reflection.TargetInvocationException' occurred in mscorlib.dll A first chance exception of type 'System.Runtime.InteropServices.COMException' occurred in mscorlib.dll An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in mscorlib.dll Additional information: Invalid callee. (Exception from HRESULT: 0x80020010 (DISP_E_BADCALLEE)) I get the same error whether initialize yi with a new obj, a new Array2D, or null. How does F# translate VARIANT output arguments?

  • How far did DevExpress get with Javascript refactoring?

    - by MattX
    Over a year ago, I remember watching one of DevExpress evangelists previewing or at least promoting rich Javascript refactoring (beyond just limited intellisense) within the Visual Studio shell, I recall part of CodeRush/DevExpress product line. I was excited. On checking today (lmgtfy) I can find only very very limited reference to it, just one small italtic line about beta in product description, no videos, no blog posts, no community buzz. Was it dropped? Vapourware? Poor implementation that they dont even promote it? With Javascript arguably the most popular programming language ever and with a VM for it on practically every machine in last 10 years, why is editor support so poor? (Compared with those for Java and C#)? You see the likes of ScottGu bragging we now have jQuery intellisense but compare this to richness of C# support in the IDE it is a joke. Someone once said since there are many style of writing Javascript a rich IDE (beyond intellisense) with refactoring support is difficult, but if several engines can interpret/compile JS with same result surely it should be hard to analysis it to support stuff like rename variable, extract method, move to another namespace (or JS minic of it), etc.. Am I wrong?

  • OS X, Mercurial and MediaTemple problem

    - by bschaeffer
    I've installed Mercurial per MT's knowledge base file here. Working with it server side using ssh from my Mac works fine. I can initialize repositories and the like, but pulling from the server or pushing from my Mac produces an error I don't understand. Here's what I get when call hg push from my local installation (hash marks represent my server number): remote: Traceback (most recent call last): remote: File "/home/#####/users/.home/data/mercurial-1.5/hg", line 27, in ? remote: mercurial.dispatch.run() remote: File "/nfs/c05/h01/mnt/#####/data/mercurial-1.5/mercurial/dispatch.py", line 16, in run remote: sys.exit(dispatch(sys.argv[1:])) remote: File "/nfs/c05/h01/mnt/#####/data/mercurial-1.5/mercurial/dispatch.py", line 21, in dispatch remote: u = _ui.ui() remote: File "/nfs/c05/h01/mnt/#####/data/mercurial-1.5/mercurial/ui.py", line 38, in __init__ remote: for f in util.rcpath(): remote: File "/nfs/c05/h01/mnt/#####/data/mercurial-1.5/mercurial/util.py", line 1200, in rcpath remote: _rcpath = os_rcpath() remote: File "/nfs/c05/h01/mnt/#####/data/mercurial-1.5/mercurial/util.py", line 1174, in os_rcpath remote: path = system_rcpath() remote: File "/nfs/c05/h01/mnt/#####/data/mercurial-1.5/mercurial/posix.py", line 41, in system_rcpath remote: path.extend(rcfiles(os.path.dirname(sys.argv[0]) + remote: File "/nfs/c05/h01/mnt/#####/data/mercurial-1.5/mercurial/posix.py", line 30, in rcfiles remote: rcs.extend([os.path.join(rcdir, f) remote: File "/nfs/c05/h01/mnt/#####/data/mercurial-1.5/mercurial/demandimport.py", line 75, in __getattribute__ remote: self._load() remote: File "/nfs/c05/h01/mnt/#####/data/mercurial-1.5/mercurial/demandimport.py", line 47, in _load remote: mod = _origimport(head, globals, locals) remote: ImportError: No module named osutil abort: no suitable response from remote hg!

I would really appreciate any assitance on this problem. Thanks in advance!

  • Model validation with enumerable properties in Asp.net MVC2 RTM

    - by Robert Koritnik
    I'm using DataAnnotations attributes to validate my model objects. My model class looks similar to this: public class MyModel { [Required] public string Title { get; set; } [Required] public List<User> Editors { get; set; } } public class User { public int Id { get; set; } [Required] public string FullName { get; set; } [Required] [DataType(DataType.Email)] public string Email { get; set; } } My controller action looks like: public ActionResult NewItem(MyModel data) { //... } User is presented with a view that has a form with: a text box with dummy name where users enter user's names. For each user they enter, there's a client script coupled with ajax that creates an <input type="hidden" name="data.Editors[0].Id" value="userId" /> for each user entered (enumeration index is therefore not always 0 as written here), so default model binder is able to consume and bind the form without any problems. a text box where users enter the title Since I'm using Asp.net MVC 2 RTM which does model validation instead of input validation I don't know how to avoid validation errors. The thing is I have to use BindAttribute on my controller action. I would have to either provide a white or a black list of properties. It's always a better practice to provide a white list. It's also more future proof. The problem My form works fine, but I get validation errors about user's FullName and Email properties since they are not provided. I also shouldn't feed them to the client (via ajax when user enters user data), because email is personal contact data and is not shared between users. If there was just a single user reference on MyModel I would write [Bind(Include = "Title, Editor.Id")] But I have an enumeration of them. How do I provide Bind white list to work with my model?

  • jquery load and tinymce gives me a "g.win.document is null" on subsequent loads

    - by Patrice Peyre
    So... very excited as first post on stackoverflow I have this page, clicking a button will call editIEPProgram(). editIEPProgram counts how many specific divs exists, adds another div, loads it with html from '/content/mentoring/iep_program.php' and then calls $("textarea.tinymce").tinymce to add a rich text editor to the newly added text boxes. It finally adds a tab which handles the new stuff and bob is your uncle. It ALMOST works. Clicking the button the first adds everything and everything woks, on the second and subsequent click, everything is added but the tinymce fails to initiate (I guess) and gives me "g.win.document is null". I have been on it for some time now and losing all my sanity. please, help.me. function editIEPProgram(){ var index = $("div[id^=iep_program]").size(); var target_div = "iep_program_"+index; $("#program_container") .append( $("<div></div>") .attr("id", target_div) .addClass("no_overflow_control") ); $("#"+target_div).load ( "/content/mentoring/iep_program.php", {index:index}, function() { $("textarea.tinymce").tinymce({ script_url: "/scripts/tiny_mce.js",height:"60", theme:"advanced",skin:"o2k7",skin_variant : "silver", plugins : "spellchecker,advlist,preview,pagebreak,style,layer,save,advhr,advimage,advlink,searchreplace,paste,noneditable,visualchars,nonbreaking,xhtmlxtras", theme_advanced_buttons1 : "spellchecker,|,bold,italic,underline,strikethrough,|,formatselect,|,forecolor,backcolor,|,bullist,numlist,|,outdent,indent,|,undo,redo,|,link,unlink,image,cleanup,preview", theme_advanced_buttons2 : "", theme_advanced_buttons3 : "", theme_advanced_toolbar_location : "top", theme_advanced_toolbar_align : "left", content_css : "/css/main.css" }); }); $("#tab_container") .tabs("add", "#"+target_div,"New program") .tabs("select", $("#tab_container").tabs("length")-1); }
