Example of key side does not

I cut and pasted the following code on the forum which is supposed to work.

protected boolean keyDown (int keyCode, int time) {}

If (Keypad.key (keycode) == Keypad.KEY_CONVENIENCE_1) {}

takeSnapShot();

Returns true;

}

Return super.keyDown (keycode, time);

}

Thet "great return" generates the following error during the build

D:\James's Documents\Work\Blackberry Development\RadicalFlashlightStorm\com\RadicalPhotography\RadicalFlashlightStorm\RadicalFlashlightStorm.java:265: cannot find symbol
symbol: keyDown (int, int) method
location: net.rim.device.api.ui.UiApplication of the class
Return super.keyDown (keycode, time);

I watched KeyDown and it seems OK to me.

If I change the "super return" to "return false", he makes it through the construction, but does not work.  And the strange thing is that I can not put a breakpoint anywhere in the code above.  Says something invalid code.

Thanks in advance for the help!

keyDown() is not a UiApplication method - which is exactly what the compiler is trying to say.

You think that you override keyDown() in UiApplication, but you only declare a method called keyDown().

This explains why it does not compile with super.keyDown () since there is no such method in UiApplication, and (b) why it compiles well with ' return true', still does absolutely nothing because it is never called by the UI infrastructure.»

keyDown is a handler method, so you replace it on a screen or a Manager, most likley.

    Hello @pxj,

    I understand that your laptop keyboard does not work, and that your alternative keyboard does not work as well. I'd be happy to help you in this case!

    As your drivers available of the system does not contain the keyboard for Windows 7 drivers, I recommend you to get a drive recovery to re - install Windows Vista on your system. This can be done by following this document on getting a HP recovery disks or USB HP recovery disc.

    Please re-post with the results of your troubleshooting, and I look forward to your response!

    Of my knowledge Support Flash Card utility is not related to a specific model laptop.
    On my Satellite a series of laptop I installed Support utility of the Flash card that I found in the section L500 and it worked.

    Please note that we had bought a laptop Lenovo S 405 of Croma store located at Silver Bow Ludhiana.

    Thanking you,

    Yogesh clavreul,

    Hi yogesh,

    This problem could be due to the fact that the product key provided does not match the press which is used to install Windows. The product key that is provided can be a file without assistance, in a. EI. CFG file, in the PID.txt file or in the BIOS firmware. Windows OEM 8 machines ship with the product key in the firmware, and if this product key does not match the press, then you will see the above error message.

    You are able to start after receiving the error message on the screen?

    I suggest you to change the product key to the correct for the media you are trying to install. If the system has a product key in the motherboard (o. a. 3.0 [Activation OEM] provides an OEM product key in the firmware), you use an Unattend file, file (EI.cfg) edition Configuration or the product ID file (PID.txt).

    You can check the link:

  • Satellite M40X-286: energy saving and the E - key utility does not work on Vista

    First of all, sorry for my bad English.

    I managed to install Windows Vista Ultimate 32-bit on my Satellite M40X-286. Everything works, except for the energy saving and the E - key utility. I tried the added value of packages of other TOSHIBA models, but they all give an error message during the installation. Is there a solution for this problem?

    Now I can't change the speed of the processor and the brightness of my screen, and I can't even adjust these settings in a power mode. The only way to change the brightness is manually using the FN + F6 and F7 keys.

    Kind regards
    Stijn.

    Please don t be crazy about me, but there is no problem at all. The situation is quite clear.

    First: tools and utilities are similar, but in most cases have to be adapted for each laptop model. It may happen that some tools work on the different model of laptop, but this does not mean that he has to work on each model.

    Second important fact is that Toshiba does not Satellite M40X support for Vista operating system and I guess you won't be able to use this tool. In my opinion, it is not so important, because all the energy-saving settings you can find in Vista power options.

    For utility E - key, I don't see a solution. If you use OS not supported, you must live with it.

  • Qosmio G30-223: keyboard key '2' does not work in console/konsole/xterm in Debian

    Hello

    I installed debian on a qosmio g30-223, it works correctly except the key of a keyboard in console/konsole/xterm.
    Under KDE, all the keys work but when I'm under a console (without xorg), konsole or an xterm, the '2' key (shift + a) does not work.

    It is a french keyboard layout and a card keyboard fr-latin9. Before connecting, the key also works.

    Any ideas?

    Hi face,.

    I have gentoo with 2.6.17 kernel and windowmaker as office. I know this problem. Maybe it s an idea to check the file xorg.conf to map keyboard under X then to change the keymap under console as X replaces the console overview.
    If the worst comes to the worst, try "dpkg - reconfigure console - data ' to choose a new layout for your page layout.
    I think that there are more keymaps under the hull for french available key-layouts, just to play with it. :)
