How to make a bootable usb disk for windows?

This is the best solution I could find in the net for making a DOS bootable disk. Thanks VistaX64!

Once you are done with the steps, don't get upset if you see no files in the USB. It happens to me in my Windows XP but still the disk has the required files to boot. You can copy any additional files you need into the disk and use them once it is booted.

Error #2130: Unable to flush SharedObject. at Error$/throwError()

Check your application url for some extra /. For me something like http://<ip>/<context>//index.html caused the error.

Invalid Embed directive in stylesheet - can't resolve source 'Embed(source = "my_resource.swf", symbol = "my_skin")'

If you are getting just one or two errors in your css, check the path of those resources.

Are you getting hundreds of such errors in your css, for all the resources? Then your css might be good ;-) Just comment out the css file in your source and take a look, you might have some broken embed resource path in your code (mxml or as). Fix it, you will be good.

How to access internal variables in Flex/Action Script 3?

Import the namespace mx_internal

//your existing imports
import mx.core.mx_internal;

Tell Actionscript that is a namespace
use namespace mx_internal;

Prefix the property name with mx_internal::
<instance>.mx_internal::<internal var/method>

HTTP Basic Authentication - GET - passing headers in ActionScript 3

Unfortunately I couldn't figure out anyways to handle this. Player discards the headers you set in a GET request. My SSO was okay for a POST, and in POST headers will be included if you pass some dummy parameters along with the request.

If it appears as a bug, check your dataProvider. You might have data points outside the range of Y-Axis.

If you have to live with the faulty data, then disable the filterData property of the series.
