  • Data validation between SQL replicated tables

    - by Vikram
    Hi All, I am trying to figure out a way to validate the data in my publisher and subscriber in SQL 2005 replication. I thought of using sp_publication_validation, but it needs db_owner permission and we are not allowed to have it in our company. So I did bit more reading and found out about two other SPs that I think work for me. First one is sp_article_validation, which I plan to run on the publisher. For each article that I call this SP, its gonna give the row count and a checksum. With that info, I intend to call sp_table_validation on the subscriber, passing the row count and checksum from the previous SP, there by validating both tables. What do you guys think? Is this a proven way to validate data in replication? There is very little documentation on these SPs. Here is the link: sp_table_validation - http://msdn.microsoft.com/en-us/library/aa239370(v=sql.80).aspx sp_article_validation - http://msdn.microsoft.com/en-us/library/ms177511(v=SQL.90).aspx Thanks for

  • using jQuery .live with .bind

    - by Aninemity
    okay, I understand the basics of jQuery, and I know that in some instances I've had to use .live('click',function(){...}); instead of .click(function(){...}); to get the method to fire correctly. the method I'm currently looking at is: $('#title').bind('keyup', function(){...}); This works great, except because it's in a bit of code that isn't called until another action is preformed, I'd need to use .live() as described above. Problem is, I don't know how to format this one to work using the .live() method instead of .bind() as shown above. Can someone please help? Thanks in advance!

  • how to make a simple database app in android?

    - by Iakovl
    i am not an android developer, prefer C# but i want to play with andorid a bit since i have a android device, apologize in advance for it. i want to make a simple app in android with the basic CRUD functions (create, read, update and delete) while the basic option is to use SQLiteOpenHelper i've seen DAO generators (like greenDAO) that make life more simple as i see it. so the first question is what DAOgenerator to use (if it all)? next is how to properly show it, while i know i need listview i still don't figure out exactly how to bind the database to it and to the querys i'll make for proper display each time i make a new query from a "search" screen, to the main "list display" screen

  • USB device Set Attribute in C#

    - by p19lord
    I have this bit of code: DriveInfo[] myDrives = DriveInfo.GetDrives(); foreach (DriveInfo myDrive in myDrives) { if (myDrive.DriveType == DriveType.Removable) { string path = Convert.ToString(myDrive.RootDirectory); DirectoryInfo mydir = new DirectoryInfo(path); String[] dirs = new string[] {Convert.ToString(mydir.GetDirectories())}; String[] files = new string[] {Convert.ToString(mydir.GetFiles())}; foreach (var file in files) { File.SetAttributes(file, ~FileAttributes.Hidden); File.SetAttributes(file, ~FileAttributes.ReadOnly); } foreach (var dir in dirs) { File.SetAttributes(dir, ~FileAttributes.Hidden); File.SetAttributes(dir, ~FileAttributes.ReadOnly); } } } I have a problem. It is trying the code for Floppy Disk drive first which and because no Floppy disk in it, it threw the error The device is not ready. How can I prevent that?

  • Are there any standard one-click install/lauch mechanisms for the web?

    - by Niklas Bäckman
    The reason I ask is mostly due to how Google Chrome installation works once you click the "Accept and install" button from Firefox. After you click the installation is started directly and when it's completed Chrome itself starts up. Firefox does not show any "Save" or "Confirm" dialogs after you click the Install button (on Chrome install web page). Now, is this standard behaviour? Or might it be due to having an old version of Chrome already on the computer (Note: The new version was still installed from Firefox). Seems a bit risky to me, all you have to do is fool the user to click something and then you can do whatever you want on his machine, or? Personally I thought things like this only worked with IE/ActiveX.

  • Store data in Ruby on Rails without Database

    - by snowmaninthesun
    I have a few data values that I need to store on my rails app and wanted to know if there are any alternatives to creating a database table just to do this simple task. Background: I'm writing some analytics and dashboard tools for my ruby on rails app and i'm hoping to speed up the dashboard by caching results that will never change. Right now I pull all users for the last 30 days, and re arange them so I can see the number of new users per day. It works great but takes quite a long time, in reality I should only need to calculate the most recent day and just store the rest of the array somewhere else. Where is the best way to store this array? Creating a database table seems a bit overkill, and i'm not sure that global variables are the correct answer. Is there a best practice for persisting data like this? If anyone has done anything like this before let me know what you did and how it turned out.

  • Array-size macro that rejects pointers

    - by nneonneo
    The standard array-size macro that is often taught is #define ARRAYSIZE(arr) (sizeof(arr) / sizeof(arr[0])) or some equivalent formation. However, this kind of thing silently succeeds when a pointer is passed in, and gives results that can seem plausible at runtime until things mysteriously fall apart. It's all-too-easy to make this mistake: a function that has a local array variable is refactored, moving a bit of array manipulation into a new function called with the array as a parameter. So, the question is: is there a "sanitary" macro to detect misuse of the ARRAYSIZE macro in C, preferably at compile-time? In C++ we'd just use a template specialized for array arguments only; in C, it seems we'll need some way to distinguish arrays and pointers. (If I wanted to reject arrays, for instance, I'd just do e.g. (arr=arr, ...) because array assignment is illegal).

  • Specifying routes by subdomain in Express using vhost middleware

    - by user730569
    I'm using the vhost express/connect middleware and I'm a bit confused as to how it should be used. I want to have one set of routes apply to hosts with subdomains, and another set to apply for hosts without subdomains. In my app.js file, I have var app = express.createServer(); app.use...(middlware)... app.use(express.vhost('*.host', require('./domain_routing')("yes")); app.use(express.vhost('host', require('./domain_routing')("no")); app.use...(middlware)... app.listen(8000); and then in domain_routing.js: module.exports = function(subdomain){ var app = express.createServer(); require('./routes')(app, subdomain); return app; } and then in routes.js I plan to run sets of routes, dependent on the subdomain variable passed in is "yes" or "no". Am I on the right track or is this not how you use this middleware?

  • Libxml2: undefined reference to xmlTextReaderConstName

    - by Dmitry
    I have installed the latest libxml2-2.8.0, as usual: $ ./configure, $ make, $ make install. The $ xml2-config --cflags --libs gives this output: -I/usr/local/include/libxml2 -L/usr/local/lib -lxml2 -lm But trying to compile any example... $ gcc `xml2-config --cflags --libs` xmltest.c The linker says: /tmp/cc8ezrPl.o: In function `processNode': xmltest.c:(.text+0x19): undefined reference to `xmlTextReaderConstName' xmltest.c:(.text+0x38): undefined reference to `xmlTextReaderConstValue' ...etc. Anything I've googled can be solved by xml2-config --cflags --libs flags, or upgrading to the latest version of libxml2, or something. Unfortunately, neither works for me. What can be the steps to identify the problem? Using Ubuntu 12.04 64-bit.

  • update portlet without refreshing portal page

    - by mike
    I'm trying to create a simple agena portlet. Now I've developed a basic one using spring-portlet-mvc, it allows you to navigate to the next and previous month with thusly named links that invoke a previousMonth or nextMonth function in my controller. Now the problem I'm having is that this navigation causes my whole page to refresh. Now I was wondering what the best way to fix this was. I've been looking around a bit and it looks like jquery/ajax will do the trick, but since I don't have any experience yet with that technology I was wondering if anyone had any pointers/better ideas to solve my problem.

  • Storyboard changing controller (modal) not working

    - by BrandNew
    I have problem with navigation between ViewControllers: here is my storyboard: http://postimg.org/image/dar9pkuvl/ The navigation between controllers in green rectangle works fine, I add to controller number 1 controller number 2 (by addtosubview) and then controllers number 3,4,5 to UIScrollView in controller number 2 ( controller number 2 contain scrollview). Everything work fine but if I click Send buttn on controller 4 nothing happens (It is strange because I was added connection between button and controller in the same way like between controllers 7 and 8). I know it is little bit confusing described, but I hope that someone tell me where is problem. Thanks

  • Creating a System.Windows.Controls.Image throws an exception - how do I use the dispatcher to instan

    - by Scott Whitlock
    I'm running my unit tests on a piece of code that does the following in the test: Assert.IsNotNull(target.Icon); Inside the getter for the Icon property, I'm doing this: System.Windows.Controls.Image img = new System.Windows.Controls.Image(); That's throwing this exception: System.InvalidOperationException : The calling thread must be STA, because many UI components require this. I understand what that means, and I understand that I need to use the Dispatcher, but I'm a bit confused about how or why... this is a property of my ViewModel and I don't get any of these exceptions when running the application. Other info: this only started failing when I upgraded to .NET 4.

  • Deploying locally compiled binaries on server

    - by nano
    Hi, I have a Zen based VPS server that runs on a dual-core AMD Opteron 64-bit machine. I have some locally developed C++ based daemons that I would want to deploy in that machine. My local machine is an Intel core 2 duo laptop. Can I execute binaries compiled from source code on my machine directly on the above mentioned server? I am a newbie in this area. Would be great if someone could throw light on the standard practices in this kind of situation. Thanks in advance

  • Is pthread_spin_trylock safe inside of sigsegv handler of multithreaded application?

    - by TWMouton
    I am trying to implement a handler that on SIGSEGV will collect some information such as process-id, thread-id and a backtrace and write this information to a file/pipe/socket. The problem lies in that there is the (probably pretty high) possibility that if one thread experienced a SIGSEGV that the others will shortly follow. If two threads happen to make it to the bit of code where they're writing their report out at the same time then they'll interleave their writing (to the same file). I know that I should only be using async-signal-safe functions as detailed in signal(7) I also have seen at least two cases here and video linked in top answer here where others have used pthread_spin_trylock to get around this problem. Is this a safe way to prevent the above problem?

  • How do customize the g:sortableColumn?

    - by kakaotalk
    Well, I have one column in my list that I need to customize, the thing is grails' own g:sortable doesn't work. For instance, my first column shows employee ids, then my second column, shows the employees full name where full name is a combination of first name and last name. I got it to work, sorting and all, but when I try to place it in a table with g:sortable, the g:sortable just wouldn't work. I'm thinking about passing params around but it's a bit tricky. Any suggestions? I've looked around the internet, and seems like nothing. :\

  • In Drupal, can you control block display according to e.g. number of URL parts?

    - by james6848
    I'm having a little trouble controlling page-specific block display in Drupal... My URL's will be of this typical structure: http://www.mysite.co.uk/section-name/sub-page/sub-sub-page The 'section-name' will effectively be fixed, but there will be many sub-pages (far too many to explicitly reference). I need to somehow control block display as follows: One block will show on all pages where URL contains 'section-name/sub-page' but not on pages 'section-name/sub-page/sub-sub-page' Conversely, another block will show on all pages where URL contains 'section-name/sub-page/sub-sub-page' but not on pages 'section-name/sub-page' My only idea is to do a bit of PHP that looks for the string 'section-name' and then also counts URL parts (or even the number of slashes). Not sure how to implement that though :) Your help would be appreciated!

Please help me out.

  • Are there viable alternatives for Web 2.0 apps besides lots of Javascript?

    - by djembe
    If you say find C-style syntax to be in the axis of evil are you just hopelessly condemned to suck it up and deal with it if you want to provide your users with cool web 2.0 applications - for example stuff that's generally done using JQuery and Ajax etc? Are there no other choices out there? We're currently building intranet apps using pylons and a bunch of JavaScript along with a bit of Evoque. So obviously for us the world would be a better place if instead something equivalent existed written in like PythonScript. But I've yet to seen anything approaching that aside from the Android system's ASE - but obviously that's something rather unrelated. Still - if browsers could support other scripting languages....

  • Confusion between JPA and Hibernate cascading

    - by Jay
    I'm using Hibernate 3.6 and have my code annotated (versus using hibernate mapping files). I ran into the known "problem" of using JPA cascading options that are not compatible with Hibernate's CascadeType (see this link for more info http://www.mkyong.com/hibernate/cascade-jpa-hibernate-annotation-common-mistake/). I was hoping to get a bit more clarification on the problem. I have some particular questions: 1) So @Cascade({CascadeType.SAVE_UPDATE}) works for saveOrUpdate(), but does it apply also if I use merge() or persist()? or do I have to use all three Hibernate CascadeTypes? 2) How do I decide whether to use JPA cascade options or the Hibernate @Cascade annotation instead? 2) There is a "bug" filed against this in Hibernate, but the developers apparently see this as a documentation issue, (I'm completely disagree with them), and I'm not seeing that it was addressed in said documentation. Anyone know why this is "working as designed" and not a bug in Hibernate's JPA implementation? Many thanks in advance.

  • Applying transformations to NSBitmapImageRep

    - by Adam
    So ... I have an image loaded into an NSBitmapImageRep object, so I am able to examine the contents of specific pixels via a two dimensional array. Now I want to apply a couple of "transformations" to the image, in preparation for some additional processing. If I was manipulating the image manually, in Photoshop, I would: Rotate the image Crop a portion of it and discard the rest Apply a "threshold" transformation (which essentially converts the image to black and white, based on the threshold value I provide) Resample the image to shrink it down a bit (which, although losing some image quality, will speed up the subsequent processing) (not necessarily in that order) Are there objective C methods available to facilitate these specific image manipulations, with the data in the NSBitmapImageRep object? If so, can someone point me to some good examples?

  • Jquery: Setting permanent height to an specific tab & resize plugin

    - by charlieCodex
    I am working with jquery sliding tabs. I have found a resize plugin that helps the tabs adjust to expanding content. The only thing is that i want to set a permanent height to tab 1(st_content_1). The code i have below works but it is a bit faulty. Should place in the function if statements? Check for the height of the first tab and then set it? Or a any better solution? You can check my EXAMPLE. Jquery $('.st_tab_view').resize(function() { var height = 250 $('div#st_content_1').css('height', height+'px'); var $this = $(this); $this.closest('.st_view').css('height', $this.height()); });

  • Strange type in c++

    - by Cemre
    I have a method with the prototype: bool getAssignment(const Query& query, Assignment *&result); I am a bit confused about the type of the second param (Assignment *&result) since I don't think I have seen something like that before. It is used like: Assignment *a; if (!getAssignment(query, a)) return false; Is it a reference to a pointer or the other way around ? or neither ? Any explanation is appreciated. Thanks.

  • What to do when using Contract.Assert(true) and the method must return something?

    - by devoured elysium
    I have a bit of code with the following logic: //pseudo-code foreach (element in elementList) { if (element is whatever) return element; } } In theory, there is always one element that is whatever, so this method should pose no problems. In any case, I've put an assertion on the end of the method just to be sure: //pseudo-code foreach (element in elementList) { if (element is whatever) return element; } } Contract.Assert(true, "Invalid state!"); The problem is that as this method has to return something, and the compiler doesn't understand that the assertion will break the program execution. Before using Contracts, in these kind of situations, I used to throw an Exception, which solved the problem. How would you handle this with Contract.Assert()? Returning null or default(element_type) after the Contract.Assert() call knowing it will never be called and shutting up the compiler? Or is there any other more elegant way of doing this? Thanks
