  • C#: Deal with xml, treeview datagridview and datatables

    - by renulren
    Hi all, I am working on a project that pulls data out of an xml files and also uses a tree-grid combination in order to display the data. For example depending on the selected treeview node, the datagridview will display only the records related to that node. What do you think it would be the appropriate approach in dealing with this? Thanks!

  • Visual Studio Stop Debugging on IE Close - WebSite?

    - by Mark
    Hi all, Would like to know if there is a setting anywhere which causes debugging to automatically stop when IE closes, and also if there is a way for this to work the other way around and IE to close if debugging stops. I know that this works when the project type I'm working on is a 'Web Application', I'd like to know if the same functionality exists when working on a 'Web Site' Thanks all.

  • What can you do and not do with java annotations?

    - by swampsjohn
    The typical use-case is for simple things like @Override, but clearly you can do a lot more with them. If you push the limits of them, you get things like Project Lombok, though my understanding is that that's a huge abuse of annotations. What exactly can you do? What sort of things can you do at compile-time and run-time with annotations? What can you not do?

  • Does knowing a Natural Language well help with Programming?

    - by Earlz
    We all hear that math at least helps a little bit with programming. My question though, does English or other natural language skills help with programming? I know it has to help with technical documentation, but what about actual programming? Are certain constructs in a programming language also there in natural languages? Does knowing how to write a 20 page research paper help with writing a 20k loc programming project?

  • Is it possible to create a patch using a set of changelists?

    - by webXL
    Problem: 2 projects shared trunk and were updating some of the same files. Now one project needs to be released, so a new branch was created from a checkpoint before the projects started. I have a list of just my changelist numbers from the mainline. Using that I can generate a list changed files and diff output using a script with a series of 'p4 describe #' commands. Can I reformat that output and apply it to the new branch somehow?

  • Authentication mechanism comparison

    - by Heavy Bytes
    I have to start a new project where user authentication/management will be required. A lot of websites use existing authentication mechanisms like facebook/twitter/openID/google/etc (even SO). While I might understand that they are used to simplify some parts of this workflow can someone enumerate the pluses and minuses of using one of these authentication mechanisms vs. an usual user creation and what should I look for when I do this? Thanks in advance!

  • No IO exception reported for socket operation when the interface is removed

    - by user352536
    The wifi network is connected, the application setup a socket connection and exchange data with the remote server. But when turn off the wifi, the inteface is removed, while socket operation read/write on this socket is still like normal, no any IO exception reported. The application has to do some extra checking to avoid waiting for the data forever. Is this the normal case for Android design? Is there any plan to fix it?

  • Drupal menu permissions question

    - by Luke
    I'm creating an admin module for my client that gives then access to some administration functionality concerning their content. I'm starting off my adding some permissions in my module by implementing hook_perm: function mymodule_perm() { return array( 'manage projects', ); } I can then create my menu by adding to the admin section that already exists: function mymodule_menu() { $items['admin/projects'] = array( 'title' => 'Projects', 'description' => 'Manage your projects.', 'page callback' => 'manage_projects_overview', 'access callback' => 'user_access', 'access arguments' => array('manage projects'), 'type' => MENU_NORMAL_ITEM, 'weight' => -100, ); $items['admin/projects/add'] = array( 'title' => 'Add project', 'access arguments' => array('manage projects'), 'page callback' => 'mymodule_projects_add', 'type' => MENU_NORMAL_ITEM, 'weight' => 1, ); return $items; } This will add a Projects section to the Administration area with an Add project sub section. All good. The behavior I want is that my client can only see the Projects section when they log in. I've accomplished this by ticking the "manage projects" permission for authenticated users. Now to give my client actual access to the Administration area I also need to tick "access administration pages" under the "system module" in the users permissions section. This works great, when I log in as my client I can only see the Projects section in the Administration area. There is one thing though, I my Navigation menu shown in the left column I can see the following items: - Administer - Projects - Content management - Site building - Site configuration - User management I was expecting only the see Administer and Projects, not the other ones. When I click e.g. Content Management I get a Content Management titled page with no options. Same for Site Building, Site Configuration and User Management. What's really odd is that Reports is not being shown which is also a top level Administration section. Why are these other items, besides my Projects section, being shown and how can I make them stop from appearing if I'm not logged in as administrator?

  • How do I get the cursor back in VS2010rc winforms designer after drawing controlls?

    - by Allen
    Not sure if this is a bug or if i'm just missing something but I cannot for the life of me figure out how to get my cursor back in the winforms designer in visual studio 2010. I opened up an existing project and added a group box, now my cursor is stuck drawing group boxes. I just want the simple pointer cursor back but nothing I do seems to bring it back. I almost expected it to be on the toolbox under "Cursor" but its not.

  • I wrote a new X11 keyboard layout file, how do I get my system to recognize it?

    - by grimborg
    I like to configure my keys my way, so I wrote a keyboard symbols file and I put it in /usr/share/X11/xkb/symbols/cat I use it by running setxkbmap cat -variant dvorak (and it works), but it doesn't show up in the console configuration (dpkg-reconfigure console-setup) nor in the Gnome keyboard settings... nor anywhere else, so I have to run setxkbmap every time. I suppose that I have to register it somewhere, but where? Any hints? Thanks!

  • Change encoding to UTF-8 recursively on Windows?

    - by Pekka
    Does anybody know a tool, preferably for the Explorer context menu, to recursively change the encoding of files in a project from / to UTF-8 and other encodings? Freeware or not too expensive would be great. Edit: Thanks for the answers, +1 for all of them as they are all fine but I am a lazy bastard sometimes, and would really like to be able to just right click a folder and say "convert all .php files to UTF-8". :) Further suggestions are appreciated.

  • Hibernate Distributed Cache

    - by DD
    Hi, I'm looking to setup Hibernate with distributed cache where I have one application writing to the DB and another one reading from the DB. Is there an easy way to notify the reading application when the writing one has written through Hibernate? The distributed cache will invalidate the cache but I need the reading application to know a change has been made to refresh its data immediately. Thanks, D

  • Good Software development courses?

    - by user296970
    I'm a software developer with a BS in Computer Science. I've been working in the field for 5 years, and I'm looking to develop my project leadership skills (I'm currently not a lead). Does anyone have any suggestions as to which schools / programs I can do? A masters is probably out of the question, due to the time required (and my not so good verbal score on my GRE). A shorter course would be preferable.
