flash - Flex canvas with many UIComponents, if one moved are others redrawn/reprocessed? -

July 15, 2012

I have a host named Canvas in the form of several UICmans, sometimes up to 1000 or 3000 items. It's okay for now, because they are not interactive.

But, according to the mouse movement I added a 'marker line' (a pixel wide UI component with colored background) in the canvas. When this UICM sponsorship is added to the host canvas and moves, then everything goes down under the crawl. i.

Do you think this might be why? Or how to avoid?

Each time you move the mouse, you're probably working < How to call / code> and updateDisplayList all those UIComponent s You can create those thousands of components with their neighbors to interact with their status and dimensions again.

  Without looking at my code, I can not be very specific in recommending a solution, but you canvas with a transparent background on the  which divides thousands of components, its Matches the dimension and location, and uses the marker to move the line.

Short URL Outbound Link Tracking in PHP and MySQL -



    I have a site that reduces the link based on this topic. I decided that it would be great if users click on a small URL, like HootSuite users can track their links. I currently have a database in which the short URL is placed with the actual URL and this click count will ideally update the click count column when that small URL is accessed by an external user.   In short, I am looking for a PHP / MySQL solution so that many small URLs can be clicked. . Any additional information gathered from the clicks will also be highly appreciated.

In section round line 11 where it determines the position of 301, you can redirect with the database update. Something like    $ query = mysql_query ("update`" $ database. "` .```_AL_DIRED`Set count = count + 1 where` small '=' ".mysql_escape_string ($ short) , $ Db); $ Line = ...

However, what I need to do is here something like gallery here Only completes without javascript and ajax:     I want a selection number to show below the main image as soon as the user clicks the thumbnail, the page Selected new Highlight the image and the series of thumbnails on boto goes forward one by one if its not the last image.   How do I do this? Do I need a quick and dirty way to do this? I am using php and mysql for the database here - just need code to show 'paged' images below the main image. I know how to install everything i.e. Thumbnail size etc ...      I do not know the number of your rows in MySQL for T-SQL As there is a ROWNUMBER () function, but to do this, it is a smart way to sequential numbering of your images in the database. From there, you ask something ...
