  • cakephp datetime insertion behaviour

    - by littlechad
    hi everyone this is a cakePHP question about datetime database insertion mismatch, i jumped in to this project while the whole thing is already built around 70%. here's what happen, every time i insert a data that contain a datetime, the inserted time doesn't match the inputted date, and the mismatch has no pattern or what ever, in some table the differences is 5 hours, while in others it could be 12 hours, 7 hours, or even 15 hours. i have traced this by investigating the controller, the model, the app_controller, everything but i don't find anything that indicate a datetime insertion rules. if the view : echo $form->input('start_date', array('label' => __l('start date')); i can't even find in the controller anything like: $this->data['current_controller']['start_date'] = $this->data['current_controller']['start_date']; when i use pr($this-data); to print the posted data, this is shown: [start_date] => Array ( [month] => 02 [day] => 16 [year] => 2011 [hour] => [min] => [meridian] => ) so i figured doing something like: $yearMonDay = $this->data['current_controller']['start_date']['year']."-"; $yearMonDay .= $this->data['current_controller']['start_date']['month']."-"; $yearMonDay .= $this->data['current_controller']['start_date']['day']; if(!empty($this->data['current_controller']['start_date']['hour'])){ $hourMinSec = $this->data['current_controller']['start_date']['hour'].":"; $hourMinSec .= $this->data['current_controller']['start_date']['min'].":"; $hourMinSec .= $this->data['current_controller']['start_date']['meridian']; }else{ $hourMinSec = "00:00:00"; } $this->data['Deal']['start_date'] = $yearMonDay." ".$hourMinSec; just to make sure the funny thing is that those posted datetime is inserted into the database with the mismatch value anyway. it's getting pretty frustrating, is there any suggestion on where else should i find the codes that define how the datetime should be inserted? or probably give me a clue on how to override those mismatched insertion rules? thanks

  • Is there any standalone application which would export WF4 designer functionality?

    - by Sergej Andrejev
    I read that it is possible to host WF4 designer in standalone application outside Visual Studio 2010, in fact I tried it too. But main problem with it is missing intelisence. Therefore the question: Does anyone know about whether there are open source (or not OS) projects which add this missing functionality to standalone WF4 designer? Even better if it's a universal ready-to-use application

  • Jquery/Ajax file uploader

    - by Ihavenoidea
    Hey Guys Im looking for a jquery or ajax file uploader, Im currently using the FancyUploader which worked great until Flash brought out their update making all flash progress bars absolete, now whenever I try to upload large files... it will fill the progress bar to 100% in a matter of seconds even though the actual upload finished minutes after. So im now looking for a new uploading script that DOESNT require flash but can still display the progress. Any suggestions?

  • I need to know inside of "while(fscanf != EOF){blah}" if the next fscanf is going to return EOF-- be

    - by Rancur3p1c
    I've got some code executing in a while(fscanf != EOF) loop. However, even when fscanf has finished executing, I need to keep running that code until some conditions are met. I mean I guess I could copy/paste the code to outside the while(fscanf) loop, and only use global variables, but that seems messy. Surely someone has encountered something like this before and has a cleaner solution.

  • How to use Multiple Variables for a lock Scope in C#

    - by Gunner
    I have a situation where a block of code should be executed only if two locker objects are free. I was hoping there would be something like: lock(a,b) { // this scope is in critical region } However, there seems to be nothing like that. So does it mean the only way for doing this is: lock(a) { lock(b) { // this scope is in critical region } } Will this even work as expected? Although the code compiles, but I am not sure whether it would achieve what I am expecting it to.

  • Livevalidation clientside validation - can you control the position of the validation messages?

    - by JK
    I'm using LiveValidaion for my clientside validation http://livevalidation.com/ and DataAnnotations for my validation rules. This all works fine except that the clientside error messages are only ever displayed to the right of the element being validated. Is it possible to move this validation message below the element being validated? Or even better, group all messages in a div at the top/bottom of the page? I dont see anything in their docs or examples

  • SSAS error when deploying cube in BIDs

    - by user282382
    I am getting the following error when deploying. This is in a cube which was working fine, all that has changed is a key column in one of the dimensions. Internal error: Failed to generate a hash string I have no idea what is causing this but even if I change the dimension back to how it was and try to deploy I get the same error. If anyone has seen this or knows how to fix it please respond.

  • Ad-hoc retreival of data from SQL Server varbinary column

    - by Daniel Fortunov
    I would like to retreive some binary data from a varbinary(max) column in a SQL Server database for debugging purposes. What is the easiest way to get this data into a local binary file, preferably without having to write a throw-away console application? I have tried using SQL Server Management Studio but this returns a hex encoded binary string, rather than raw binary data (even with the "results to file" option).

  • mouse wheel operates on scrollbar

    - by basicblock
    If a SWF file or even a component within it has scrollbars, wouldn't it make sense that if the user is hovered over that area (it's in focus) and uses the mouse wheel, that this movement would automatically translate to the scrollbar moving. Any ideas how this is done, the events or classes used for this? I'm open to outside components or classes too. I haven't started yet, but I'll do an item renderer because it's easy to give it scrollbar.

  • m2eclipse sets JDK compliance to 1.4

    - by jihedamine
    Using eclipse 3.5, when I create a new maven project, m2eclipse automatically adds J2SE1.4 to libraries and Compiler Compliance Level to 1.4 (Project properties Java Compiler). My JRE system library is 1.6 and my default compiler compliance level is 1.6. I don't even have 1.4 installed. Can I make m2eclipse use my default settings and prevent it from modifying project settings?

  • Query.fetch(limit=2000) only moves cursor forward by 1000 entities?

    - by Liron
    Let's say I have 2500 MyModel entities in my datastore, and I run this code: query = MyModel.all() first_batch = query.fetch(2000) len(first_batch) # 2000 next_query = MyModel.all().with_cursor(query.cursor()) next_batch = next_query.fetch(2000) What do you think len(next_batch) is? 500, right? Nope - it's 1500. Apparently the query cursor never moves forward by more than 1000, even when the query itself returns more than 1000 entities. Should I do something different or is it just an App Engine bug?

  • Is there a way to clear all JavaScript timers at once?

    - by Jens
    Im building an automatic refreshing comment section for my website using jQuery .load. So I am using a javascript 'setTimeout' timer to check for new comments. But after doing some stuff like changing comment pages or deleting (all using ajax), a few old timers keep running, even though I used clearTimeout before loading new ajax content. Is there some way to clear ALL javascript timers when I load new ajax content?
