I'm trying to load images from a relative folder /media/one.jpg but it never loads, I use the same script to load from my local folder and it does.
The absolute path e.g c:/mydir/one.jpg does not work either. Earlier I used to throw things at my server and get jpegs from there. But for testing purposes I need these images locally available.
Any Idea?
Just solved it Use loadImage("media\ears.jpg"); double slash instead to single and it works :)
For security reasons flash files can access only web or only local files, with can be set in the project properties. If you want to build a web application like a webpage or just a part of a webpage, than you should choose network only, but this way you can test your work only on a webserver (that can be localhost too ). If you want to build a desktop application, witch has no relation to web, then select the "local only" option in your project properties.

I'd like to have an html file that organizes certain files scattered throughout my hard drive. For example, I have two files that I would link to:
C:\Programs\sort.mw
C:\Videos\lecture.mp4
The problem is that I'd like the links to function as a shortcut to the file. I've tried the following:
Link 1
Link 2
... but the first link does nothing and the second link opens the file in Chrome, not VLC.
My questions are:
Is there a way to adjust my HTML to treat the links as shortcuts to the files?
If there isn't a way to adjust the HTML, are there any other ways to neatly link to files scattered throughout the hard drive?
My computer runs Windows 7 and my web browser is Chrome.
You need to use the file:/// protocol (yes, that's three slashes) if you want to link to local files.
Link 1
Link 2
These will never open the file in your local applications automatically. That's for security reasons which I'll cover in the last section. If it opens, it will only ever open in the browser. If your browser can display the file, it will, otherwise it will probably ask you if you want to download the file.
You cannot cross from http(s) to the file protocol
Modern versions of many browsers (e.g. Firefox and Chrome) will refuse to cross from the http(s) protocol to the file protocol to prevent malicious behaviour.
This means a webpage hosted on a website somewhere will never be able to link to files on your hard drive. You'll need to open your webpage locally using the file protocol if you want to do this stuff at all.
Why does it get stuck without file:///?
The first part of a URL is the protocol. A protocol is a few letters, then a colon and two slashes. HTTP:// and FTP:// are valid protocols; C:/ isn't and I'm pretty sure it doesn't even properly resemble one.
C:/ also isn't a valid web address. The browser could assume it's meant to be http://c/ with a blank port specified, but that's going to fail.
Your browser may not assume it's referring to a local file. It has little reason to make that assumption because webpages generally don't try to link to peoples' local files.
So if you want to access local files: tell it to use the file protocol.
Why three slashes?
Because it's part of the File URI scheme. You have the option of specifying a host after the first two slashes. If you skip specifying a host it will just assume you're referring to a file on your own PC. This means file:///C:/etc is a shortcut for file://localhost/C:/etc.
These files will still open in your browser and that is good
Your browser will respond to these files the same way they'd respond to the same file anywhere on the internet. These files will not open in your default file handler (e.g. MS Word or VLC Media Player), and you will not be able to do anything like ask File Explorer to open the file's location.
This is an extremely good thing for your security.
Sites in your browser cannot interact with your operating system very well. If a good site could tell your machine to open lecture.mp4 in VLC.exe, a malicious site could tell it to open virus.bat in CMD.exe. Or it could just tell your machine to run a few Uninstall.exe files or open File Explorer a million times.
This may not be convenient for you, but HTML and browser security weren't really designed for what you're doing. If you want to be able to open lecture.mp4 in VLC.exe consider writing a desktop application instead.
If you are running IIS on your PC you can add the directory that you are trying to reach as a Virtual Directory.
To do this you right-click on your Site in ISS and press "Add Virtual Directory".
Name the virtual folder. Point the virtual folder to your folder location on your local PC.
You also have to supply credentials that has privileges to access the specific folder eg. HOSTNAME\username and password.
After that you can access the file in the virtual folder as any other file on your site.

By the way, this also works with Chrome that otherwise does not accept the file-protocol file://
Hope this helps someone :)

I have a webserver running on a storage server and I am looking to access some of the media on it (ie. use an image from the nas as a background on the page). I have tried this with no luck:
background-image:url("file://SERVER01/Media/Family/5102.jpg");
as well as other variations, such as:
background-image:url("file:///SERVER01/Media/Family/5102.jpg");
background-image:url("file://../Media/Family/5102.jpg");
background-image:url("file:///../Media/Family/5102.jpg");
When I access the page from my laptop, the background image is broken, but if I look at the source and copy the link (Only the ones with SERVER01 in them) directly in, the image pops up fine.
What is the best way of troubleshooting this? What is the safest way of using these images without compromising the security of my server?
In order to access files on your remote server you will need to use a public facing hostname & URI, you cannot use local file paths outside of the doc root because it will not be visible to the client / website user.

Sometimes I need to write a small program just to represent some data in a chart, or similar stuff. I have been wanting to do this kind of things through the browser, with HTML5. I think it would be nice to use its canvas to create a nice UI for simple apps.
I have read some articles related to offline applications with HTML5, but they focus on downloading all the data you need and save it to the cache to use it offline later. You even need to set up an Apache server (or similar) to create your app.
I don't need my app to be online, just in my computer. I just want to create a simple application, nothing to do with internet at all.
How can I do this? Is it even possible or worthy? Is there any "Hello world!" tutorial about this around there?
Something like Mozilla Prism would be good for displaying the content as an application.
There's no need to have a web server like Apache for just displaying HTML5/Javascript in a browser. You can just have it all in a folder on your desktop and then load it in the browser with the file:// protocol.
For example file://C:/Documents and Settings/YourUser/Desktop/YourApp/index.html would open an HTML file in a folder called YourApp on your user's desktop.
If you ever find you need to read static HTML+Javascript files locally then I'd recommend using this python command in the console:
python -m SimpleHTTPServer
It launches a simple HTTP server (who'd of guessed) that serves files from the current working directory. Effectively, it's the same as launching an apache webserver, putting some static assets in /var/www/... etc. etc.
You could also just browse to the assets at file:///some/folder; however, most browsers will prevent javascript from using AJAX when files are loaded in that way, which will manifest as a bunch of bugs when you go to load it.
