I have to create a Mozilla Firefox plugin that will help in taking remote access to other computer. I am actually a newbie to this and know nothing how to get it started. I tried googling it but all articles shows the creation of Firefox extension. Can anyone please guide me to some tutorial where it shows how to create a plugin for video or audio. Thanks in advance and please excuse my silly question.
Thanks

Downloads
All the code I’ve created here is available both as a ZIP file of everything, so you can start experimenting, change stuff and see what happens. It is also available as an XPI file, which you can install in your Firefox just to test the functionality (drag and drop it into Firefox).
Download Link Target Finder code as a ZIP file.

I am creating a MacOS application to take an audio file chosen by the user and display its sound waves in a timeline. Like the one below.
I have searched Google and Stack Overflow for a few hours and only found IOS examples. Every time I tried to take one and convert it to work with MacOS there were conflicting libraries used.
If you could provide me with some code to get started or a source/article that has information that would be great.
Thanks In Advance!
AudioKit can display waveforms using AKTableView. It is cross platform and there's an example of how to load files into one on of the framework's playgrounds, which is also shown online here:
http://audiokit.io/playgrounds/Basics/Tables/
The code is simple so even if you need to add to it, you can pull the necessary parts from AudioKit and place it in your own project, if you don't want to add all of AudioKit to your project just for this one feature.

I am working on VS2008. i have been given the project of Onlline Teachers Evaluation System. I was working in a WEBSITE named as Class. Last time i was working on it I made many changes. I added many new forms integrated them saved the changes and shut down the system. Now when i've opened it those files are simply not there in Class project. I had set the home.aspx as startup page. if i run it on local host it says homme page not found. The same thing happened before and i had to make whole thing again from scratch. Does anybody know what could be the reason??
This is not a Visual Studio issue. The files you had previously saved simply aren't there. So the question is: why did the files disappear? I can think of 4 possible causes:
You're opening the wrong project: the project you worked on last time has the same name, but it's located at a different location on your disk.
Someone has installed version control on your system rolled back your changes.
Someone restored a backup image of your disk.
You have serious hardware problems.
Or maybe it's something else equally strange or unexpected. Hopefully knowing that Visual Studio has nothing to do with this will help you.

I am recently start work in Joomla and I have an error please help me
Fatal error: Class 'JFactory' not found in joomla/helpers/system.php
on line 48 the line show in 48 row is
$this->application = JFactory::getApplication();
Firstly, ensure you have the latest version of the build you're using. So either 1.5.26, 2.5.8, or 3.0.2
Once done, download a fresh copy of Joomla, extract the "includes" and "libraries" folders, and upload these 2 folder (preferably as zip files) via the FTP and extract them.
As a little side note. If you already have, please don't edit any core Joomla files. This can cause all sorts of problems on the security and functionality side of things.
I experienced the same issue and I later discovered that factory.php file was missing from "libraries/joomla" directory. I'm not sure how that happened but I replaced the file from an update zip file and that solved it.

I just tried to upload an *.odt file to my Google Docs. So far, everything worked fine, except that the images do not load. Has anybody got this to work? Or is it a missing feature?
I'm on OSX Lion, and I use the latest version of Google Chrome and NeoOffice (an OSX-version of OpenOffice.org).
Do you include the pictures as links/reference ? (in the dialog box to insert a picture)
You can check image src attribute value. Unzip the odt file, then open/edit content.xml and search for image tag. If the picture is included (no link/reference), you should find it in Pictures folder, next to content.xml
It seems that it has been a temporary problem, it's working now.

Mac-like text rendering on Windows? [closed]

I'm trying to figure out how to render text on Windows with the same display as Mac rendered text, e.g: http://igadgetlife.com/wp-content/uploads/2009/09/11.png (That picture is not perfect, but it showcases the neat anti aliasing that Mac has)
I've looked at GDI++/Freetype, and it seems too unstable and it has a lack of documentation. If anyone has any suggestions, that'd be great.
The reason I am asking is because I am trying to make a writing program where text readability and text display are two important factors.
Thanks
The solution lies in using gdipp to override the default font-rendering engine in Windows. Just download the latest package from their Google project page and double click to install it.
It will automatically get installed as a service. If you don't notice any change in the way fonts render, open Run -> Type services.msc -> Right click gdipp -> Click Start.
You may need to restart your computer once for all programs to start respecting gdipp's rendering engine.
EDIT: Alternatively, look at MacType. It's a user-space application that won't require being run as a service. It works with Chrome as well.
