  • Unable to use opacity animation w/ position:relative on children

    - by chovy
    Consider the following (applies to all IE6+ browsers -- including IE8): <div id="picture"> <div class="thumb" style="position: relative;"><img .. /></div> <p>Some description</p> </div> When I animate the opacity down to 0 it only works if I change the .thumb class to position: static. This has bigger problems because I use that to constrain absolutely positioned children to that container. I've tried all the hacks I have discovered, none work (bg-color, zoom, etc). You can see an example here: http://chovy.dyndns.org/test/opacity3.html I need to use position: relative on the real world case throughout the container that is getting the animation.

  • Page zoom slows down page rendering

    - by Alex
    I'm building a map viewer much like Google maps and i've run into an interesting performance problem when a page is zoomed (i.e ctrl + OR ctrl -). It seems to affect all major browsers but Firefox has the worst problems as far as I can tell. The problem is that when the page is zoomed panning by dragging the mouse seems really sluggish. This can even be seen on Google maps. Pan the map left and right and note how smooth it is. Now press ctrl+ (3 or 4 times). Now pan the map left and right in the same way. Notice the difference? Does anyone know how I can minimize this problem?

  • xval get message from resource file

    - by Rob
    I'm working on a CMS system which uses a resource file to get information and errormessages from. The client side validation is working without problems, only it's not getting the errormessage from the resource file. While debugging i figured out xval seems to get the errormessages from a javascript file where the messages are set hard-coded. Is there some way to override this? Below the code which should make the relation to the resourcefile en specify the error when the field is left empty. [Property] [Required(ErrorMessageResourceType = typeof(CMSMessages), ErrorMessageResourceName = "EnterValidMoney")] public virtual Double ShippingCost { get; set; }

  • Has anyone noticed that a WPF file dialog will pass a click through to the UI when double clicking t

    - by Ben
    I have some buttons on my WPF UI and I also need to choose files from time to time. I kept noticing strange problems where when I double-click an item in the file dialog, a button on the main UI would also get clicked. After experimenting, it seems that if you line up an item in the file dialog with a button behind it on the main UI and double click to select the file, it will single-click the button behind it as well. Has anyone else noticed this, or is it just a freak bug with the way I have my UI laid out?

  • Flatten (an irregular) list of lists in Python

    - by telliott99
    Yes, I know this subject has been covered before (here, here, here, here), but AFAIK, all solutions save one choke on a list like this: L = [[[1, 2, 3], [4, 5]], 6] where the desired output is [1, 2, 3, 4, 5, 6] or perhaps even better, an iterator. The only solution I saw that works for an arbitrary nesting is from @Alabaster Codify here: def flatten(x): result = [] for el in x: if hasattr(el, "__iter__") and not isinstance(el, basestring): result.extend(flatten(el)) else: result.append(el) return result flatten(L) So to my question: is this the best model? Did I overlook something? Any problems?

  • const TypedeffedIntPointer not equal to const int *

    - by dirk
    I have the following C++ code: typedef int* IntPtr; const int* cip = new int; const IntPtr ctip4 = cip; I compile this with Visual Studio 2008 and get the following error: error C2440: 'initializing' : cannot convert from 'const int *' to 'const IntPtr' Clearly my understanding of typedefs is not what is should be. The reason I'm asking, I'm storing a pointer type in a STL map. I have a function that returns a const pointer which I would like to use to search in the map (using map::find(const key_type&). Since const MyType* and const map<MyType*, somedata>::key_type is incompatible, I'm having problems. Regards Dirk

  • MySQL: updating a row and deleting the original in case it becomes a duplicate

    - by Silvio Donnini
    I have a simple table made up of two columns: col_A and col_B. The primary key is defined over both. I need to update some rows and assign to col_A values that may generate duplicates, for example: UPDATE `table` SET `col_A` = 66 WHERE `col_B` = 70 This statement sometimes yields a duplicate key error. I don't want to simply ignore the error with UPDATE IGNORE, because then the rows that generate the error would remain unchanged. Instead, I want them to be deleted when they would conflict with another row after they have been updated I'd like to write something like: UPDATE `table` SET `col_A` = 66 WHERE `col_B` = 70 ON DUPLICATE KEY REPLACE which unfortunately isn't legal in SQL, so I need help finding another way around. Also, I'm using PHP and could consider a hybrid solution (i.e. part query part php code), but keep in mind that I have to perform this updating operation many millions of times. thanks for your attention, Silvio Reminder: UPDATE's syntax has problems with joins with the same table that is being updated

  • What is the best jQuery based window plug-in you have ever used?

    - by Emre Sevinç
    I tried a couple of jQuery based window plug-ins but unfortunately was not satisfied with any of them. Here's what I tried: http://hernan.amiune.com/labs/jQuery-Windows-Engine-Plugin/jQuery-Windows-Engine-Plugin.html http://fstoke.me/jquery/window/ http://www.soyos.net/aerowindow-jquery.html I need following features without any compromises: Maximize, minimize (to a reasonable location such as bottom-left corner, not in the middle of the screen), drag, resize, etc. Highly and easily configurable Actively developed (this can be relaxed a little bit) Comes with good documentation (and examples) works cross-browser (I had problems in IE when I tried to use fstoke.me's implementation). The three plug-ins I have tried failed in one or more respects. I'm not looking for very fancy, animated effects, just very basic but yet adequate functionality. Any suggestions?

  • macdeployqt and third party libraries

    - by user338170
    I've got an application project that depends on a couple of shared libraries that I have created myself. According to the Qt 4.6 documentation "Deploying an Application on Mac OSX": Note: If you want a 3rd party library to be included in your application bundle, then you must add an excplicit lib entry for that library to your application's .pro file. Otherwise, the macdeployqt tool will not copy the 3rd party .dylib into the bundle. I have added lib entries to my application's .pro file but the libraries that I have written do not get copied into the bundle when I execute macdeployqt. I have the following in my .pro file: LIBS += -L../Libraries -lMyLib Everything builds okay, its just when I try to run from the bundle that I run into problems i.e. "image not found" errors. Is there a bug in macdeployqt or do I have to something more to my .pro file?

  • ERD-CLASS design

    - by Mahesh
    Hello guyz,i am new to daatbase and class diagram.I just get scenarios from internet and try to develop ERD and Class Diagram for them.But the following scenario has caused me some problems, and i am not sure about my design. "Whenever an employee fills leave application form, the leave application should be appeared for approval to his/her team leader. Team Leader has the option to change the date of requested leave and to approve or reject the leave. Employee also has the option to change date of previously unapproved leaves or to cancel any of unapproved leave. In case of team leader, he can approve his own leaves. Management should be able to create categories of leaves like (Casual, Sick, Planned work, etc) and should be able to adjust the days allocated to each type of leave". I have identified these as entities for ERD 1) Employee(I think i dont need to make entity for Technical lead,since he is an employee) 2) LeaveHistory 3) LeaveCategory Plz correct me if the system need more classes or entities

  • iPhone: fast hash function for storing web images (url) as files (hashed filenames)

    - by Stefan Klumpp
    What is a fast hash function available for the iPhone to hash web urls (images)? I'd like to store the cached web image as a file with a hash as the filename, because I suppose the raw web url could contain strange characters that could cause problems on the file system. The hash function doesn't need to be cryptographic, but it definitely needs to be fast. Example: Input: http://www.calumetphoto.com/files/iccprofiles/icc-test-image.jpg Output: 3573ed9c4d3a5b093355b2d8a1468509 This was done by using MD5(), but since I don't know much about that topic I don't know if it is overkill (- slow).

  • https://www.googleapis.com/drive/v2/files/<fileid>/comments?alt=json returned "Not Found" on a file that can't be opened

    - by Kartik Ayyar
    More details as below: https://www.googleapis.com/drive/v2/files/1iNMGIAFXuhS_CO_hnEO0_EJ9PAgT-hXYqWYv0MPGUTI/comments?alt=json returned "Not Found The file is present in drive and shows in drive.changes.list, but can't be opened in Google Drive either. There are two problems here a) the file is somehow corrupt ( it was a document imported into drive, so that failed, but that isn't something I care about for the purposes of this question ) b) The file shows up as existing in some API calls, but calls to read comments with the Drive SDK comments API fail. Here are results from an API call showing how the file does indeed exist: "file": { "kind": "drive#file", "id": "1iNMGIAFXuhS_CO_hnEO0_EJ9PAgT-hXYqWYv0MPGUTI", "etag": "\"o35FABD0TC3H-Up3OL3UA9kEB2w/MTM3MTc2NzU5NzEyNA\"", .... ....

  • MS Sql Full-text search vs. LIKE expression

    - by Marks
    Hi. I'm currently looking for a way to search a big database (500MB - 10GB or more on 10 tables) with a lot of different fields(nvarchars and bigints). Many of the fields, that should be searched are not in the same table. An example: A search for '5124 Peter' should return all items, that ... have an ID with 5124 in it, have 'Peter' in the title or description have item type id with 5124 in it created by a user named 'peter' or a user whose id has 5124 in it created by a user with '5124' or 'peter' in his street address. How should i do the search? I read that the full-text search of MS-Sql is a lot more performant than a query with the LIKE keyword and i think the syntax is more clear, but i think it cant search on bigint(id) values and i read it has performance problems with indexing and therefore slows down inserts to the DB. In my project there will be more inserting than reading, so this could be a matter. Thanks in advance, Marks

  • ASP MVC: Custom Validation Attribute

    - by user323395
    I'm trying to write my own Custom Validation attribute but i'm having some problems. The attribute i'm trying to write is that when a user logs in, the password will be compared against the confirmation password. namespace EventCompanion.Data.Attributes { public class ComparePassword : ValidationAttribute { public string PasswordToCompareWith { get; set; } public override bool IsValid(object value) { if (PasswordToCompareWith == (string)value) { return true; } return false; } } Now my problem is when i'm trying to set the attribute like this in the model file: [Required] [ComparePassword(PasswordToCompareWith=ConfirmPassword)] public string Password { get; set; } [Required] public string ConfirmPassword { get; set; } } I get the following error: Error 1 An object reference is required for the non-static field, method, or property 'Project.Data.Models.GebruikerRegistreerModel.ConfirmPassword.get' It seems that VS is not accepting the confirmpassword in the "PasswordToCompareWith=ConfirmPassword" part Now my question: What am i doing wrong? Thanks in advance!!!

  • CKEditor adds html entities to inline CSS. Is the CSS still valid?

    - by Mihai Secasiu
    I have this piece of code: <table style="background-image: url(path/to_image.png)"> And when I load it in CKEditor it's transformed in: <table style="background-image: url(&quot;path/to_image.png&quot;)"> Is this still still valid CSS? Actually I'm not so interested if it's valid but if there would be any problems with any web browser or email client ( the editor is used for composing a html email ). Firefox and Thunderbird seem to be fine with it.

  • pro*C in oracle XE

    - by srandpersonia
    I downloaded the free express edition of oracle, Oracle XE. I couldn't find the pro*c compiler in this edition. I read somewhere that oracle 9i client has pro*C, So I presumed that oracle client for 10g XE should have it too and downloaded it. But to my disappointment, I can't find it there too. :(. Is there a way to download the older oracle 9i and use it connect to 10g XE without any compatibility problems?. Or is it possible to download the pro*C compiler alone?. I don't want to download the standard editions as they are too large(2 GB). Thanks.

  • Avoiding problem of overwriting files which are in use

    - by zaf
    For example on a high traffic web server. To reduce problems when switching a file I usually rename the old file out and then rename in the new file. I was told some time ago that renaming a file does not change the 'inode data' so that processes reading the file can keep doing so without glitches. And, of course, rather than copying in the new file it is faster and safer to rename a temp copy. Is this still best practice and if not what do you do?

  • How to inject dependencies into a custom UserNamePasswordValidator in WCF?

    - by Dannerbo
    I'm using a UserNamePasswordValidator in WCF along with Unity for my dependency injection, but since WCF creates the instance of the UserNamePasswordValidator, I cannot inject my container into the class. So how would one go about this? The simplest solution I can think of is to create a static proxy/wrapper class around a static instance of a UnityContainer, which exposes all the same methods... This way, any class can access the container, and I don't need to inject it everywhere. So I could just do UnityContainerWrapper.Resolve() anywhere in code. So basically this solution solves 2 problems for me, I can use it in classes that I'm not creating an instance of, and I can use it anywhere without having to inject the container into a bunch of classes. The only downside I can think of is that I'm now potentially exposing my container to a bunch of classes that wouldn't of had access to the container before. Not really sure if this is even a problem though?

  • How to store or share live data between PHP Requests?

    - by Devyn
    Hi, I want to start a project for facebook and the application will be like real-time multiplayer chess game. The problem I'm having is I have no idea how to store the data when a player moves one piece and update the new position in player2 browser. I'm gonna use PHP, MySQL for server side and jQuery for Client Rendering. The simplest idea is to store the data in XML or MySQL and re-generate the result to player2 browser. But I know that when thousand of players are playing, it will not be an efficient way. Since I don't have time to study new language for this project, I'm gonna have to stick with PHP. I'm not going to use flash either because I want my client side light-weight and flash-free. So is there any way that will solve my problems?

  • user model password field default password field in django

    - by imran-glt
    Hi, I've created a custom user model in my application. This user model is working fine, but there are a couple of problems I have with it. 1) The change password link in the my register.html page doesn't work? 2) The default password box on the add/edit page for a user is a little unfriendly. Ideally, what I'd like is the two password fields from the change password form on the add/edit user form in the admin, which will automatically turn convert the entered password into a valid encrypted password in Django. This would make the admin system MUCH friendlier and much more suited to my needs, as a fair number of user accounts will be created and maintained manually in this app, and the person responsible for doing so will likely be scared off at the sight of that admin field, or just type a clear text password and wonder why it doesn't work. Is this possible / How do I do this?

  • jQuery Validate - can I re-validate a group of fields after changing one?

    - by Nathan Long
    I'm using jQuery Validate and would like to re-validate a group of fields whenever one of them is changed (or possibly, whenever one of them validates successfully). My attempts so far just create infinite loops. Is this possible, or does the plugin design preclude it? (Specifically, I've got a method that requires at least X of group Y to be filled out, and as soon as that's true, I'd like all those fields to re-validate. Currently I'm clearing out their error messages with my own code, but that's a hack - it also hides unrelated validation problems until the form is re-submitted.)

  • parsing raw email in php

    - by Uberfuzzy
    i'm looking for good/working/simple to use php code for parsing raw email into parts. i've written a couple of brute force solutions, but everytime, one small change/header/space/something comes along and my whole parser fails and the project falls apart. and before i get pointed at PEAR/PECL, i need actual code. my host has some screwy config or something, i can never seem to get the .so's to build right. if i do get the .so made, some difference in path/environment/php.ini doesnt always make it available (apache vs cron vs cli) oh, and one last thing, i'm parsing the raw email text, NOT pop3, and NOT imap. its being piped into the php script via a .qmail email redirect. i'm not expecting SOF to write it for me, i'm looking for some tips/starting points on doing it "right". this is one of those "wheel" problems that i know has already been solved.

  • cmake and visual studio

    - by robUK
    Hello, gcc 4.4.2 / Visual Studio C++ 2008 I have been using cmake on linux, without any problems. Now I have ported by application to run on windows. I generated the solution files using cmake -G "Visual Studio 9 2008 ../src" However, I know that cmake only creates a Makefile that is used by the compiler to build your application. I open my solution in Visual Studio, I press the F7 key to compile. I am wondering does it actually use the Makefile that was generated by cmake? Or it is just compiling the application like any normal visual studio program? Many thanks for any advice,

  • Sessionstate not being saved between pages

    - by Grant
    Hi, i am having problems with an asp.net c# site whereby i am setting a session state object to true and then redirecting to another page that needs to check the value of the session state object and it is null. Sometimes it is set correctly and other times is is simply null. When i debug on my local machine it works perfectly every time. Only when i upload to my web server does this temperamental behaviour happen. As it is based around the security of the site it is obviously important that the session data be valid and accurate every time. Is session state data unreliable? AFAIK its set to inproc, cookieless, 30 min timeout, vanilla installation of IIS. Does anyone have any suggestions? Perhaps i need to thread.sleep inbetween the storing of the session data and the reading? NB: the time between the write and the read is about 70ms.. ample time for the data to be written to RAM.....
