[waylex]

New component for Prado: Virtual Keyboard to protect against keyloggers.

Features:
- AutoIvoke="True" makes keyboard pop up automatically when page loads.
- Lightweight: 10 kb only. Doesn't require prado core js library.
- RelativeAlign="False" positions keyboard relatively to the whole page.
- Automatically pops up when ForControl gets focus.
- Automatically hides when ForControl loses focus.
- Supports inserts, backspaces and deletes at cursor position.
- May be invoked from script by using: "$F('my_text_box').keyboard.invoke();".
- Crossbrowser: IE, FF, MZ, OP, SM.


Test code:

Code:

            <com:TTextBox ID="Input" TextMode="Password" />
            <com:TKeyboard ForControl="Input" OffsetLeft="3px" OffsetTop="35px" />

P.S. See also pure CSS menu component.

Any comments and suggestions are welcome!

that is very cool and interesting concept , thanks for sharing! May be a different prefix other than 'T'?

If there is a keylogger present, it is probably a trojan, it may also have screen capture capability... still very cool I think.

Also, may be have the comments in English? my editor couldn't figure out which encoding the file was in.

Are there any way to make it impossible for the user type into the password box using the physical keyboard, letting the TKeyboard be the only input method for the password box? Because if the user click in the password box he is still able to use the physical keyboard.
Thanks!
