  • Fluent NHibernate CheckProperty and Dates

    - by Chris C
    I setup a NUnit test as such: new PersistenceSpecification<MyTable>(_session) .CheckProperty(c => c.ActionDate, DateTime.Now); When I run the test via NUnit I get the following error: SomeNamespace.MapTest: System.ApplicationException : Expected '2/23/2010 11:08:38 AM' but got '2/23/2010 11:08:38 AM' for Property 'ActionDate' The ActionDate field is a datetime field in a SQL 2008 database. I use Auto Mapping and declare the ActionDate as a DateTime property in C#. If I change the test to use DateTime.Today the tests pass. My question is why is the test failing with DateTime.Now? Is NHibernate losing some precision when saving the date to the database and if so how do prevent the lose? Thank you.

  • Checking for duplicates with nested forms

    - by Cyrus
    I'm making a rails 3.2.9 app that allows users to create pages and they can embed youtube videos through a nested form. I'm trying to figure out how to make it so that I can prevent duplicate video records from being stored in my db. So I have a Video model that takes the youtube url and just parses out the video id and stores that instead of the full user submitted youtube url, which may have extraneous url query parameters. So here's the situation that I'm trying to figure out: There's page1 with video1 - url: 123 and video2 - url: abc Then another user creates page2 and submits video3 - url: def and video4 - url: 123 Currently each page has_many videos. But I think I should change it to a many-to-many relationship. But how would I make it so that the url submitted as video4 in the nested form points to video1? Also I how would I make a nested form that creates objects that are connected through a join table?

  • font-smoothing not applied to buttons

    - by David
    I have used this snippet to prevent webkit from changing antialiasing when using CSS transforms: html{ -webkit-font-smoothing: antialiased; } This works fine for most cases, however I noticed some weirdness in chrome when playing around with Bootstrap using this HTML: <button class="btn btn-inverse">John Doe</button> <a class="btn btn-inverse">John Doe</a>? This is how it looks in OSX/Chrome: Fiddle: http://jsfiddle.net/hY2J7/. In fact, it seems that it is not applied to buttons at all. Is there a safer technique to trigger the same antialiasing in webkit for all elements?

  • Input checkbox name converts period signs into underlines on post

    - by Rakoon
    Hello I am working on an image gallery at the moment. When a user is logged in, an x appears over each image and a checkbox next to it to enable the user to delete that image. Only if the checkbox is checked will the image be deleted. They are both in a (one for each image in the gallery), the small image "x.gif" is an input type="image" that submits the $_POST form. The checkbox inherits the name of the image and is to prevent accidentally pressing the x button and deleting an image. The problem is that the checkbox name, upon posting it gets converted from (for instance) "Image.jpg" to "Image_jpg" When i test it with print_r($_POST); Should I create code for replacing _jpg or _gif into .jpg and .gif after the post or is there a way to make it possible to use period signs in input names? Any help is greatly appreciated.

  • Preventing dictionary attacks on a web application

    - by Kevin Pang
    What's the best way to prevent a dictionary attack? I've thought up several implementations but they all seem to have some flaw in them: Lock out a user after X failed login attempts. Problem: easy to turn into a denial of service attack, locking out many users in a short amount of time. Incrementally increase response time per failed login attempt on a username. Problem: dictionary attacks might use the same password but different usernames. Incrementally increase response time per failed login attempt from an IP address. Problem: easy to get around by spoofing IP address. Incrementally increase response time per failed login attempt within a session. Problem: easy to get around by creating a dictionary attack that fires up a new session on each attempt.

  • cache problem in asp.net

    - by JoelFan
    I'm seeing an issue of some static pages that are using the browser cache, which is not desired. To prevent caching, I'm setting <clientCache cacheControlMode="DisableCache" /> in the relevant <location> tag in web.config If I open the page in Firebug (in the Net tab), I see that the Response headers have Cache-Control: no-cache which is correct, but the status of the Response is 304 Not Modified! Isn't that a contradiction? How can I get it to stop caching (i.e. always send a 200 with content)?

  • How will ASP.NET AJAX be licensed?

    - by hbb
    It would be very useful if somebody could indicate what the plans are for releasing and licensing the AJAX extensions. The EULA for Beta 2 states that the software may be used for development and for web site deployment only. Redistribution is explicitly forbidden. Does that imply that it is going to be released under terms different from the .NET framework and ASP.NET or is it just a precaution to prevent developers shipping the Beta? It seems too risky to include AJAX in new products before there is some indication what the model is going to be....

  • How to hide and disable cursor globally?

    - by trudger
    I have two questions: How to hide cursor for all programs? I tried to hide the cursor by using ShowCursor, but it only works in my program. The cursor still appears when moving cursor outside of my program. How to disable mouse operations for all programs? I use SetWindowsHookEx to hook mouse and prevent other programs to processing the mouse operations. I can hook the clicks, but the problem is that I can't hook the "move". When I move the mouse to menu or system buttons ("minimize/restore/close"), they are highlighted. This means they can still "see" the mouse. Can anyone help me please?

  • php class basic question

    - by Ross
    hi <?php class myClass { var $input; var $output; function myClass($input) { $output = 'You entered: ' . $input; return $output; } } $test = new myClass; echo $test->myClass(123); ?> this works, but returns this warning: Warning: Missing argument 1 for myClass::myClass() I read in to this, and seems that the constructor is expecting a value, so by adding: function myClass($input='') the warning is removed, but this seems so unnecessary? could someone enlighten me as to why it's required to define a value to prevent that warning? thanks for any pointers

  • SQL Server 2008 Stored Procedure

    - by user238319
    I cannot store the date data type variables using stored procedure. My code is: ALTER PROCEDURE [dbo].[Access1Register] -- Add the parameters for the stored procedure here @MobileNumber int, @CitizenName varchar(50), @Dob char(8), @VerificationCode int AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; -- Insert statements for procedure here select CAST(@dob As DATE) Insert Into Access1 (MobileNo,CitizenName,Dob,VerificationCode) values(@MobileNumber,@CitizenName,@Dob,@VerificationCode) go If I exec this procedure it is executing, but there is an error occured in the date type variable. It's raising the error as invalid item '-'.

  • is unicode( codecs.BOM_UTF8, "utf8" ) necessary in Python 2.7/3?

    - by Brian M. Hunt
    In a code review I came across the following code that contains the following: # Python bug that renders the unicode identifier (0xEF 0xBB 0xBF) # as a character. # If untreated, it can prevent the page from validating or rendering # properly. bom = unicode( codecs.BOM_UTF8, "utf8" ) r = r.replace(bom, '') This is in a function that passes a string to Response object (Django or Flask). Is this still a bug that needs this fix in Python 2.7 or 3? Something tells me it isn't, but I thought I'd ask because I don't know this problem very well. Thanks for reading.

  • CDateTimeCtrl - preventing 'focus' change when setting date

    - by WalderFrey
    I'd like to use a CDateTimeCtrl to allow the user to select a non-weekend date. So, if the user increments the day (via a keypress) - and the resulting day is found to fall on a weekend - then the control should skip forward to the following Monday (don't let issues about month changes distract you, it's not relevant). Usually it's not a problem: when I handle the DTN_DATETIMECHANGE notification I can check the new date/time and if it's found to be a weekend then I can call SetTime on the control to update the date. However, if I set the style to DTS_SHOWNONE, this call to SetTime causes the control to shift the input 'focus' (term used loosely) to the 'none' checkbox, e.g. away from the day field. This prevents the user from using keyboard input to continue incrementing the date unless they subsequently use the right arrow key to reset the 'focus', which is just nasty. I would dearly like to prevent this focus shift from occurring. Is it even possible?

  • method returning wrong variable

    - by cocoanewbie
    This class I'm working with has three instance variables I'm interested in, NSmutablearrays xArray yArray and zArray, there are also other NSmutablearrays, a, bArray and c. I just added accessors - (NSMutableArray *) xArray { return xArray; } ditto for y and z. However, it's returning yArray, zArray and bArray for some reason. Why is that happening? Okay, I just changed the names of the methods to GetXArray and everything seems to be returning the right variables. Now I'm really confused. How the heck did this happen and how do I prevent this from happening in the future?

  • jQuery UI .widgets resetting scroll positions of elements contained within

    - by Derek Adair
    I am making heavy use of jQuery UI with my latest project. Unfortunately I've hit a major wall due to some really whacky behavior exhibited by the jQuery UI widgets when they contain elements with scrollbars for overflow. Check out this demo Scroll down in one of the .scroll-container elements Click an accordion header Click on old header - note the element was auto-scrolled to the top. Is there anyway to prevent this from happening? It's screwing with a major plugin of mine that utilizes jQuery scrolling. I'm flat-out lost as to what to do here! Perhaps this is a bug worth mentioning in the jQuery UI dev forums... EDIT I am using Chrome - 8.0.552.231 and OSX 10.6.5

  • Using Dom Objects in PHP, the default namespace is redeclared in some nodes.

    - by TomcatExodus
    I'm working on a template engine, having migrated from regex driven to DOM driven. It appears though, that whenever I create a DomDocumentFragment to encapsulate some portion of a document temporarily, the namespace attribute is added to each node in the fragment. Since my default namespace for a given document will 99% of the time be XHTML, it's adding the XHTML namespace declaration. Being the default namespace, this seems fruitless, and ultimately nodes in any other namespace will be stripped out at render time anyways. Aside from iteratively removing namespace attributes, is there some way I can prevent this from occurring to begin with? Its quite problematic, as this will likely increase render time filesize considerably, as large portions of a given document may be stored in a fragment. I've tried $doc->normalizeDocument(), but as I assumed, it did nothing.

  • .htaccess stupid issue

    - by justnoone
    I have a server where I can only configure httpd using .htaccess, a cannot access global configuration. I want to rewrite almost every non-existing path to index.php, so I did something like: RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?path=$1 [L,QSA] And that is ok. But another thing I want to do is to prevent access to path where I keep PHP files (I cannot store them somewhere else) which is for example /php. I would like that anything starting with /php rewrites to index.php?path=php... so I did something like: RewriteCond %{REQUEST_URI} ^/php.* RewriteRule ^(.*)$ /index.php?path=$1 [L,QSA] And that also would work ok if I had access to global configuration. In case of per-directory configuration, when I access /php it rewrites it to index.php?path=php and than puts directory name before that: /php/index.php?path=php. I read documentation and I realize that it uses internal redirects when per-directory confoguration is used. How can I avoid this behavior?

  • gevent, sockets and syncronisation

    - by schlamar
    I have multiple greenlets sending on a common socket. Is it guaranteed that each package sent via socket.sendall is well separated or do I have to acquire a lock before each call to sendall. So I want to prevent the following scenario: g1 sends ABCD g2 sends 1234 received data is mixed up, for example AB1234CD expected is either ABCD1234 or 1234ABCD Update After a look at the sourcecode I think this scenario cannot happen. But I have to use a lock because g1 or g2 can crash on the sendall. Can someone confirm this?

  • How do you write a recursive stored procedure

    - by Grayson Mitchell
    I simply want a stored procedure that calculates a unique id and inserts it. If it fails it just calls itself to regenerate said id. I have been looking for an example, but cant find one, and am not sure how I should get the sp to call itself, and set the appropriate output parameter. I would also appreciate someone pointing out how to test this sp also. ALTER PROCEDURE [dbo].[DataContainer_Insert] @SomeData varchar(max), @DataContainerId int out AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; BEGIN TRY SELECT @UserId = MAX(UserId) From DataContainer INSERT INTO DataContainer (UserId, SomeData) VALUES (@UserId, SomeData) SELECT @DataContainerId = scope_identity() END TRY BEGIN CATCH --try again exec DataContainer_Insert @DataContainerId, @SomeData END CATCH END

  • How to enforce lazy loading of entities on certain conditions

    - by Samuel
    We have an JPA @Entity class (say User) which has a @ManyToOne reference (say Address) loaded using the EAGER option which in turn loads it's own @ManyToOne fields (say Country) in a EAGER fashion. We use the EntityQuery interface to count the list of User's based on a search criteria, during such a load all the @ManyToOne fields which have been marked as EAGER get loaded. But in order to perform a EntityQuery.resultCount(), I actually don't need to load the @ManyToOne fields. Is there a way to prevent loading of the EAGER fields in such cases so that we can avoid the unnecessary joins?

  • How do you stop a dynamically loaded form from submitting with jquery?

    - by Zak
    I'm working on an AJAX login system. Right now, when the user clicks on a link, the login form is dynamically loaded when the person clicks on a "log in" link. Since I'm using AJAX for this, I want to prevent the form from actually submitting when the submit button is clicked. I tried the following code as part of my load function, and the form loads correctely, but the form still submits normally. $('#loginBox').load('loginform.php'); $('#loginBox form').submit(function(event) { event.preventDefault(); }); How can I fix this?

  • I'm having a hard time wrapping my head around handling the Activity Lifecycle...

    - by kefs
    So it seems i've created a fatal flaw and coded an app before understanding/handling rotation/lifecycle events.. Currently, all of my code is in onCreate of each activity. I've read a lot of lifecycle tutorials online, including the official dev guide info, but i'm still having an almost unbelievably hard time trying to wrap my head around the rotation/lifecycle events/methods and when to use them correctly. For example, my app currently has an activity that opens the db, inserts a record, then closes the db.. if i rotate my screen on this activity, the data is re-entered into the db. Using the available lifecycle events (onPause(), onResume(), etc..), how would I prevent this db call from happening again? Would I have to pass a variable through the state saying that the db call has been done, and not to do it again? Thanks in advance..

  • Should every class have its own namespace?

    - by thehouse
    Something that has been troubling me for a while: The current wisdom is that types should be kept in a namespace that only contains functions which are part of the type's non-member interface (see C++ Coding Standards Sutter and Alexandrescu or here) to prevent ADL pulling in unrelated definitions. Does this imply that all classes must have a namespace of their own? If we assume that a class may be augmented in the future by the addition of non-member functions, then it can never be safe to put two types in the same namespace as either one of them may introduce non-member functions that could interfere with the other. The reason I ask is that namespaces are becoming cumbersome for me. I'm writing a header-only library and I find myself using classes names such as project::component::class_name::class_name. Their implementations call helper functions but as these can't be in the same namespace they also have to be fully qualified!

  • style sheet issue

    - by dotnetrocks
    When I add text to my web page using my text editor it display styles correctly inside the text editor which basically is a iframe. After this data is saved it's displayed on another page where the issue occurs. I wanted the description section on my web page to use its own style without getting overwritten by the page styles. Do i need to use a iframe to display this data? Is there a way I can prevent a block from using the page style. Please advise. Appreciate all your help.

  • HTML/JS: open other website without associated coockies

    - by Tim
    I have a web shop which sends my customers to a pretty popular website to redeem their just purchased product (at my site). However, I keep getting complaints that the product has been redeemed at the wrong account. Because the other website is that popular, it often appears that when the customers computer is shared by others the wrong account was logged in (automatically by a coockie). Now I'm wondering which steps I can take to prevent this from happening, since I don't have control over the other website (which does not make clear enough who's logged in). Is there some way to open another website without its coockies?
