mxml - What does {variable} do in flex -

-

I'm using {} around the variable in MXML, in fact to understand what they are. I need to know now that I should use it around a variable .. What happens like this?

In this case, this means that The label will display the contents of "variable", if you change the value of "variable" then it will also change the text displayed by the label.

The virtualbox will not recognize USB as a hard drive when installing an ISO In virtualbox, you have to create a virtual hard disk. Make a USB drive and tell the virtual box to install a virtual hard drive that you just created.
