• How to check if an element is really visible with javascript.

  - by Macha

  In javascript, how would you check if an object is actually visible. I don't just mean checking the visibility and display attributes. I mean, checking that the element is not visibility:hidden or display:none underneath another element scrolled off the edge of the screen. EDIT: For technical reasons, I can't include any scripts. I can however use prototype as it is on the page already. EDIT 2: This is no longer neccesary, but I'd still find an answer interesting)

• Using CreateOrthographicOffCenter in XNA

  - by Jeffrey Kern

  I'm trying to figure out how to draw graphics in XNA, and someone else suggested this. But before I attempt to use this... If I create and use this camera, and set LEFT,TOP to 0 and WIDTH=256 and HEIGHT=240, anything I render to the screen will use these coordinates? So a box with a width and height of 1, if set to 0,0 will take up space from 0,0 to 1,1?

• GLSL: How to get pixel x,y,z world position?

  - by Rookie

  I want to adjust the colors depending on which xyz position they are in the world. I tried this in my fragment shader: vec4 pos = vec4(gl_FragCoord); // get pixel position but it seems that the z-coord is always towards my camera... how do i make the coords independent from my camera position/angle? Edit: if it matters, heres my vertex shader: gl_Position = ftransform(); Edit2: changed title, so i want world coords, not screen coords!

• fire an intent from the onCreate method in android

  - by Sephy

  Maybe my question might seem a bit weird, but I have an activity in which, in one case , I have to move to another activity before it finishes loading the screen. My condition is in the onCreate method, which means when I encounter it, i get a "startActivity called from outside an activity context" error and the app just crashes... But then, is there an easy way like a flag for the intent to make it work without having the activity context resolved? thanks for any answer

• Why is my web page left-aligned on iPad?

  - by Andrew

  I recently built a site and centered it using margin: 0 auto. I also wrapped elements in a .wrapper class with a width set to 960px and then had the parent element extend across the whole browser. When I view the Brands screen on an iPad though, the site is left-aligned and does not extend across the whole window. Any thoughts to why this might be happening, and how to correct it? See below for a screenshot:

• How can I display the camera view in the main window in real time?

  - by Mongrel Warfare

  I'm trying to make an augmented reality application with a waypoint structure, like Yelp, and I'm wondering how to set up my main view so that it displays the camera view on the whole screen. I've heard of using the UIImagePickerController Class, but I'm unsure how to manipulate the code so that it doesn't actually take a picture, but just stays in the view mode. Any help would be appreciated, thanks!

• running same query in different databases

  - by user316833

  I wrote a query that I want to run in several access databases. I have 1000+ access databases with the same tables (same names, same fields). So far, I have been manually copying this query from a txt file to the sql view in the access query design screen for each database and then run it. I did not need to change the query language - everything is the same for the 1000 databases. Is there a way to automate this?

• Sifr Horizontal Menu with LI

  - by Rosaiani

  Hello, I am designing a very simple horizontal menu with sIFR and CSS list. The thing about it is that it assigns a certain width to it that makes texts of different widths´ spacing look weird on screen. I´ve seen a default width and height of a certain amount, but what I need is to make it so that the flash is exactly the size of the text. Has anyone bumped into this issue before? Thanks!
