Notes Client - sending crazy key combinations to interact with Windows
In my earlier blog entry I showed how to refresh the Notes Client UI with F5 sending key presses from code.
Using the same technic you can do some wild stuff, since you can almost simulate any keypress on the keyboard.
In an Action button you could for example:
- create email (CNTL + M)
- log out of Notes (CNTL +F5)
- lock Windows Windows key + L)
- show emoji bar (Windows key +.)
- show previews of open applications (Windows key + tab)
- print screen (ALT + PrnScr)
Also you could play back longer sequences of keypresses:
Robot robot = new Robot();
robot.setAutoDelay(500);
//WinKey + Q search
robot.keyPress(KeyEvent.VK_WINDOWS);
robot.keyPress(KeyEvent.VK_Q);
robot.keyRelease(KeyEvent.VK_WINDOWS);
robot.keyRelease(KeyEvent.VK_Q);
//C
robot.keyPress(KeyEvent.VK_C);
robot.keyRelease(KeyEvent.VK_C);
//m
robot.keyPress(KeyEvent.VK_M);
robot.keyRelease(KeyEvent.VK_M);
//d
robot.keyPress(KeyEvent.VK_D);
robot.keyRelease(KeyEvent.VK_D);
//enter
robot.keyPress(KeyEvent.VK_ENTER);
robot.keyRelease(KeyEvent.VK_ENTER);
//D
robot.keyPress(KeyEvent.VK_D);
robot.keyRelease(KeyEvent.VK_D);
//I
robot.keyPress(KeyEvent.VK_I);
robot.keyRelease(KeyEvent.VK_I);
//R
robot.keyPress(KeyEvent.VK_R);
robot.keyRelease(KeyEvent.VK_R);
//enter
robot.keyPress(KeyEvent.VK_ENTER);
robot.keyRelease(KeyEvent.VK_ENTER);
try it ! :-)
This will go to Windows Search, and search for CMD, open the Command Prompt, and enter the DIR command.
So you are probably wondering ...can I also open it in Administrator mode and do "bad stuff"? :-)
No..., it seems the keyboard buffer is ignored .... fortunately :-)
(you do need to have a pause in between commands, 0,5 second is maybe a little long but you can better see what is going on then)
What about a scheduled agent in Domino?.....
