Problem with keyboard: some keys return two, not one, characters
I have a MacBook Air 11 '' mid-2012 128 GB SSD model running OS X Yosemite 10.10.5 and my keyboard has developed a strange problem occultation key repeat. Whenever you press the "3" button, the system generates thus simultaneously a '3' and '6 '. This motif is repeated this diagonal of the keyboard down, i.e.
'3' generates a '3' and '6 '.
'e' generates an 'e' and a 'y '.
"d" generates a "d" and an "h".
'c' generates a 'c' and a "n".
The reverse is also true, that is, a '6' generates a '3' and so on. Curiously, the sign '=' generates a character "§" as well, a special character generated by keeping down option and pressing "6".
(This combo generates a ' § ' and a ' £', hidden under the '3'.)
The same problem occurs when you use the Shift or Control keys as modifiers.
I can work around the problem by using either a connection wireless Bluetooth or wired USB keyboard (like using the "Keyboard Viewer" option under "System Preferences"), but that kind of defeats the point of having a laptop as a MacBook Air, Yes? The problem is intermittent, but becomes very annoying. (Try to type a password with such a mess!) It sounds like a mechanical problem requiring a possible replacement of the sale wholesale (and), but I hope someone out there can have a software or another solution. Thank you!

That certainly points to make it a hardware problem. It is difficult to imagine a software problem that would not affect both internal and external keyboards.

Problems with the shortcut keys, suggestions?
I have an Asus computer is a portable computer, N56VM. I have problems with my shortcut keys. I can use is no longer the fn + key that usually let me adjust the back of my bright keyboard commands, or my volume (mute, raise/lower the volume), however, my brightness on the monitor shortcuts keyboard still works, and so did my black screen key. Oh, and also, my toggle mouse shortcut is not no longer works. I was looking at the forums, and I upgraded my bios and also reinstalled my ATKPI files and still nothing. I think the problem might have to do with the mechanics of the system, but I am not sure. Any suggestions?

can perform us two actions with a single button in two clicks, one after the other?
Mr President.
can perform us two actions with a single button in two clicks, one after the other?
I want that when I click on the button Add once it add data to the database and when I click again on this button it clears the form data to the empty fields.
Concerning
TanvirIn the code, it should be easy.
The following code adds that a button called butman with text 'ADD '.
It then registers a listener that will be called if the user clicks the button.This listener then calls the runAddData method if you clicked butman while it contained the text of "ADD" and it calls the runClearData method otherwise.
That's why he will swap the functionality of the button between ADD and CLEAR on each click.final Button butman = new Button("ADD"); butman.setOnAction(new EventHandler
() { @Override public void handle(ActionEvent t) { if (butman.getText().equals("ADD")) { butman.setText("CLEAR"); runAddData(); } else { butman.setText("ADD"); runClearData(); } // END IF-THEN }}); I hope that's what you wanted.
Further reflection.
You might want to run the ADD and CLEAR methods in their own son so that it can run in the background without slowing down your user interface.I also reuse rather a single button for several features instead of to apply with hundreds of nodes used only rarely with masses of code to show and hide as needed.
