  • Editing XML Literals Embedded Expressions in Visual Basic 2010 (Avner Aharoni)

    The implicit line continuation feature in Visual Basic 2010 provided an opportunity to improve the code editing experience in XML literals embedded expressions. In Visual Studio 2008, pressing Enter inside an embedded expression would result in the cursor being positioned to the left of the end embedded expression tag. In Visual Studio 2010, pressing Enter inserts a newline for the cursor, and the end embedded expression tag moves to the line below. This minimizes the number of key strokes needed...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Enhance GIMP’s Image Editing Power with Gimp Paint Studio

    - by Asian Angel
    Does your GIMP installation need a little super-charging? Using Gimp Paint Studio you can add a wonderful set of brushes, tools, and more to GIMP and take your work up to the next level. For our example we chose to install the beta version of Gimp Paint Studio on Ubuntu 10.10. Once you download the .zip file and unzip it, all that you need to do is manually transfer the contents shown here to the appropriate GIMP folders on your system. You can see the location of the destination folders here on our system… Note: Make certain to make a back-up copy of the “sessionrc and toolrc files” before you transfer Gimp Paint Studio into your installation (in case you would like to or need to revert back to the originals later). When you finish transferring the files start GIMP up and get ready to have fun. And if your experience is like ours then you should see a noticeable difference in window size and arrangement from the default settings. Here are some samples of the exceptional artwork done by Ramon Miranda and Mozart Couto using Gimp Paint Studio. Really impressive! Artwork by Ramon Miranda & Mozart Couto. Watch the introduction video and see Gimp Paint Studio in action.

  • SharePoint Content and Site Editing Tips

    - by Bil Simser
    A few content management and site editing tips for power users on this bacon flavoured unicorn morning. The theme here is keep it clean!Write "friendly" email addressesRemember it's human beings reading your content. So seeing something like "If you have questions please send an email to [email protected]" breaks up the readiblity. Instead just do the simple steps of writing the content in plain English and going back, highlighting the name and insert a link (note: you might have to prefix the link with mailto:[email protected]). It makes for a friendlier looking page and hides the ugliness that are sometimes in email addresses.Use friendly column and list namesThis is a big pet peeve of mine. When you first create a column or list with spaces the internal name is changed. The display name might be "My Amazing List of Animals with Large Testicles" but the internal (and link) name becomes "My_x00x20_Amazing_x00x20_List_x00x20_of_x00x20_Animals_x00x20_with_x00x20_Large_x00x20_Testicles". What's worse is if you create a publishing page named "This Website is Fueled By a Dolphin's Spleen". Not only is it incorrect grammar, but the apostrophe wreaks havoc on both the internal name for the list (with lots of crazy hex codes) as well as the hyperlink (where everything is uuencoded). Instead create the list with a distinct and compact name then go back and change it to whatever you want. The end result is a better formed name that you can both script and access in code easier.Keep your Views CleanWhen you add a column to a list or create a new list the default is to add it to the default view. Do everyone a favour and don't check this box! The default view of a list should be something similar to the Title field and nothing else. Keep it clean. If you want to set a defalt view that's different, go back and create one with all the fields and filtering and sorting columns you want and set it as default. It's a good idea to keep the original AllItems.aspx (note the lack of space in the filename!) easy and unfiltered. It's also a good idea to keep your column count down in views. Don't let every column be added by default and don't add every column just because you can. Create separate views for distinct responsibilities and try to keep the number of columns down to a single screen to prevent horizontal scrolling.Simple NavigationThe Quick Launch is a great tool for navigating around your site but don't use the default of adding all lists to it. Uncheck that box and keep navigation simple. Create custom groupings that make sense so if you don't have a site with "Documents and Lists" but "Reports and Notices" makes more sense then do it. Also hide internal lists from the Quick Launch. For example, if most users don't need to see all the lookup tables you might have on a site don't show them. You can use audience filtering on the Quick Launch if you want to hide admin items from non-admin users so consider that as an option.Enjoy!

  • 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.

  • Editing Routes in ASP.NET MVC

    - by imran_ku07
    Introduction :        Phil Haack's had written two great articles about Editable Routes, Editable Routes or Editable Routes Using App_Code.These Article are great. But if you not need to unit test your Routes and don't care about restart Application Domian during editing your Routes then global.asax file is the fastest and easiest to achieve the same. In this Article I will use Global.asax file instead of Global.asax.cs file for defining Routes and you will also see how this whole process will works.   Description :          You just need to Cut (or Copy) the code inside Global.asax.cs and paste it in Global.asax inside runat server tag.          You can simply do this by cutting the code of Global.asax.cs,          and paste it inside Global.asax,               Easy and quick ,Now you can change Global.asax without compiling the application. How this works :        I think it is worth here to see what is happening here.        Actually, ASP.NET will use Global.asax file to create a class named global_asax within ASP namespace and place all the code in Global.asax inside the class global_asax class which is created at runtime,                namespace ASP               {                    public class global_asax: NerdDinner.MvcApplication                    {                         //Any definitions defined in Global.asax like Application_Start method                                     }               }         Which inherits from class defined in Application tag,      <%@ Application Codebehind="Global.asax.cs" Inherits="NerdDinner.MvcApplication" Language="C#" %>          Actually ASP.NET creates a pool of application objects of this class, which varies from 1 to 100. Every request take one of these application objects to a serve incoming requests. After receiving an application object then it will call application specific events, like Application_Start(for only firstRequest), Application_BeginRequest(for every request), and so on. Therefore if these methods are defined in global_asax class then ASP.NET will call these method from global_asax, if not then it will use base class methods may be defined in Global.asax.cs(the concept known as shadowing or hiding). Summary :        In this article, I showed how easily and quickly you can make your Routes Editable. But also note that any change in global.asax results in Application Domain restart and this technique also makes your Route Unit Test difficult.

  • Best/Preferred software for photography.

    - by chills42
    I am just getting into photography as a hobby, and am looking for some good tools for image uploading/browsing/editing. I am currently using the Canon EOS utility that came with the camera for uploading, Picasa for browsing, and GIMP for editing. Pros: The files are stored using the standard file system (no proprietary library like iPhoto) Great photo editing possibilities Free (except the Canon Utility, but that was bundled) Cons: Multiple programs Hard to view the Exif Data (I like the way that iPhoto displays the data) Over-simplified editing tools in Picasa What other tools should I look into? Also, I occasionally shoot in RAW, and would prefer Mac support (better monitor), but I also have windows and linux machines.

  • Emacs protection against simultaneous editing by same user

    - by Peter Eisentraut
    Emacs has elaborate protection against simultaneous editing by two different users. If there a way to have that same facility for protecting against simultaneous editing by the same user? With lots of windows and workspaces open, it's easy to reopen a file that you already have open somewhere else. But because it does not detect a lock conflict when you open the file, you will only learn about the collision when you save.

  • Making the popup toolbar menus on Windows XP's taskbar stay put during editing

    - by NT
    Hello, I'm looking for a way to make the popup toolbar menus on Windows XP's taskbar stay in place while you edit it, and only close when you tell it to--by clicking outside it, for example. Right now it disappears after each editing action--such as renaming a file or changing its position on the menu, and you have to click the again to pop the menu back up to do more editing. Any suggestions on this issue would be greatly appreciated. Thanks, NT

  • How can I make vim show the current class and method I'm editing

    - by dcrosta
    Does anyone know if it's possible (or know of an existing vim script or plugin) that can create a "status bar" that shows the name of the current class and method (or function) I'm editing? I'm imagining that it would plug into the syntax parser for the filetype of the current buffer, and display a breadcrumb trail to show you what you're currently editing. I don't know vimscript well enough to suggest any more than that, but if there aren't any good solutions already, I may begin to hack on one, so suggestions as to where to start are welcome, too!

  • Editing sqlcmdvariable nodes in SSDT Publish Profile files using msbuild

    - by jamiet
    Publish profile files are a new feature of SSDT database projects that enable you to package up all environment-specific properties into a single file for use at publish time; I have written about them before at Publish Profile Files in SQL Server Data Tools (SSDT) and if it wasn’t obvious from that blog post, I’m a big fan! As I have used Publish Profile files more and more I have realised that there may be times when you need to edit those Publish profile files during your build process, you may think of such an operation as a kind of pre-processor step. In my case I have a sqlcmd variable called DeployTag, it holds a value representing the current build number that later gets inserted into a table using a Post-Deployment script (that’s a technique that I wrote about in Implementing SQL Server solutions using Visual Studio 2010 Database Projects – a compendium of project experiences – search for “Putting a build number into the DB”). Here are the contents of my Publish Profile file (simplified for demo purposes) : Notice that DeployTag defaults to “UNKNOWN”. On my current project we are using msbuild scripts to control what gets built and what I want to do is take the build number from our build engine and edit the Publish profile files accordingly. Here is the pertinent portion of the the msbuild script I came up with to do that:   <ItemGroup>     <Namespaces Include="myns">       <Prefix>myns</Prefix>       <Uri>http://schemas.microsoft.com/developer/msbuild/2003</Uri>     </Namespaces>   </ItemGroup>   <Target Name="UpdateBuildNumber">     <ItemGroup>       <SSDTPublishFiles Include="$(DESTINATION)\**\$(CONFIGURATION)\**\*.publish.xml" />     </ItemGroup>     <MSBuild.ExtensionPack.Xml.XmlFile Condition="%(SSDTPublishFiles.Identity) != ''"                                        TaskAction="UpdateElement"                                        File="%(SSDTPublishFiles.Identity)"                                        Namespaces="@(Namespaces)"                                         XPath="//myns:SqlCmdVariable[@Include='DeployTag']/myns:Value"                                         InnerText="$(BuildNumber)"/>   </Target> The important bits here are the definition of the namespace http://schemas.microsoft.com/developer/msbuild/2003: and the XPath expression //myns:SqlCmdVariable[@Include='DeployTag']/myns:Value: Some extra info: I use a fantastic tool called XMLPad to discover/test XPath expressions, read more at XMLPad – a new tool in my developer utility belt MSBuild.ExtensionPack.Xml.XmlFile is a msbuild task used to edit XML files and is available from Mike Fourie’s MSBuild Extension Pack I’m using a property called $(BuildNumber) to hold the value to substitute into the file and also $(DESTINATION)\**\$(CONFIGURATION)\**\*.publish.xml to define an ItemGroup all of my Publish Profile files. Populating those properties is basic msbuild stuff and is therefore outside the scope of this blog post however if you want to learn more check out MSBuild properties & How To: Use Wildcards to Build All Files in a Directory. Hope this is useful! @Jamiet

  • Interactive manifest editing with the Automated Installer Manifest Wizard

    - by Glynn Foster
    Oracle Solaris 11.2 adds a new Automated Installer (AI) Manifest Wizard to allow administrators to more easily create AI manifests for use in provisioning new client systems in the data center. The AI Manifest Wizard is a web web based interface that steps administrators through the basics of the AI manifest - target disks and layout selection, additional ZFS pools and datasets, IPS publisher and package selection, and the creation of any Oracle Solaris Zone virtual environments. The end result is an AI manifest without having to directly edit XML, and this can then be associated with an appropriate AI service. To get started, check out How To Create an Automated Installer Manifest with an Interactive Wizard

  • Cannot see boot options after editing grub background

    - by cipricus
    After solving this problem I managed to get myself into truble again out of nothing by trying to change the display of the dual boot option page in Boot Customizer. I have changed the background, the fonts size (I have increased them) and font style (I have chosen UnDotum). But Boot Customizer gave me an error (I mean a message that the application was closed unexpectedly or smth). I have restarted BootCustomizer and the settings were there. When I rebooted, instead of the normal boot options list, just the background image that I had selected and nothing else. I used Boot Repair to repair grub, it says it did it successfully, but I still get the background image when I try to boot. Any ideas? (Could it be the matter that I chose UnDotum font style? That was installed in Lubuntu - but how could it be accessible in displaying boot options?) The contents of etc/default/grub are: # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1" I have tried to modify etc/default/grub: GRUB_HIDDEN_TIMEOUT=0 to 10 GRUB_HIDDEN_TIMEOUT_QUIET=true to false and GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to "" but it doesn't help Also, using Shift doesn't make the list visible.

  • How to handle editing a large file for a non-technical user

    - by Luke
    I have a client who is given a tab delimited .txt file containing hundreds of thousands of rows. I have a user story as follows: As a user I want to take the text file and add a new value at the end of each line which contains the concatenated value of two of the columns. for example if the file read text_one text_two I need to output the following (preferably to a .txt file) text_one text_two text_onetext_two My first approach was to ask the vendor supplying the file to do the concatenation before providing the file, the easiest way to solve a problem is to eliminate it right? however they are very uncooperative and have point blank refused. I've looked at building a simple javascript application that does this client side so a non-technical user could select the file using a file selector. This approach has a few problems The file could be over a GB in size and so can't be loaded straight into memory, I've tried and the browser crashes There is no means to write a file in javascript so I'd need to output the content to the screen and have the user save it (somehow) I was thinking if I could get around the filesize limitations I could just output the edited content to the page and have the user save the page as a .txt file, however I think there is a better way than using javascript that will still accommodate the users lack of technical know-how. Please consider this question to be stack agnostic, but bear in mind that a nice little shell script or python script would be deemed unsuitable for a non technical user unless there is a way of "packaging" it nicely for a non-technical user. Updates The file is too large to open in excel. The process needs to be run weekly, but it doesn't require scheduling or automation...(yet)

  • Editing /.config/dconf/user

    - by user86322
    I am having a problem with Gnome3 (actually, I have it set to fallback mode, or Gnome 2). I have two displays and I need an X screen (I used nvidia-xconfig and nvidia-settings to do this) for each screen. However, every time I either restart X or log in, Gnome seems to be adding the objects values under /gnome/gnome-panel/layouts (ex. first time I set the two separate X screens I had clock, then log out/in, there was clock and clock1 under objects, and then log out/in there were three, clock, clock1, clock2,.......log out/in, ............30 times....clock, clock1, clock2, ......clock 42.....!! The same thing goes for top-panels, menu-bars, etc.) After a while, I found out I could remove all those using the dconf-editor, going to /gnome/gnome-panel/layouts, removing all the repetitions under fields objects-id-list and top-id-list and leaving one value of each object. This is not a solution but at least allow me to keep using Linux without so much problem. However, the problem persists every time I restart X or log in. I now finally learned about "dconf" and where the user profile settings are located (~/.config/dconf/user) and one can use "dconf" to see the keys. In my case, I need to change/remove many keys (all those clocksX, workspace-X, menu-bar-X, etc., where goes from 1 to 42 and still counting) so it's really tedious and boring to be changing one by one using "dconf write". So I found "dconf dump", which actually allow me to dump everything into a .txt file and edit the file really quick (i.e, "dconf dump / >> dump_user.txt"). The problems? Two of them: How do I "load" back "dump_user.txt" I edited into the user profile? (I read somewhere there was a "dconf reload" but reload doesn't exist as a command under "dconf") How do I stop Gnome from keep adding more objects to my desktop environment every time I log in/restart X? NOTE: The problem doesn't occur when I set the displays to use TwinView feature (i.e., the desktop is extended/shared by both displays). However, for my case I need two separate X's. Any help/suggestion would be greatly appreciated. Thanks

  • GUI for editing Menu in Xubuntu

    - by Borsook
    I see that Xubuntu has package Gnome-menus, but I cannot find the command to run the editor it should contain. I found a small editor but it does not allow new entries and alacarte tries to install whole Gnome... So I'm looking for a menu editor that will allow me to: Add new launchers, Edit existing ones Move existing ones to different categories Create new categories Won't install bazillion dependencies :)
