Installed midlet found in BB 8300

Hey there,

I am trying to install an app that will provide me with all the keys that are pressed (J2ME) key codes. It works fine in the default sun java emulator, but does not work in the BB emulator or the device. Can someone help me find out why this is happening?

This is the Canvas class that I wrote for the app. I think, a mistake, or even not at all, is present in this class:

Code *.

Javax.microedition.lcdui import. *;

SerializableAttribute public class KeyCanvas extends Canvas {}

String st = "";
String [] line = null;

public KeyCanvas() {}
row = new String [1];
line [0] = m;
}

{} public void paint (Graphics g)
g.setColor (0xFFFFFFFF);
g.fillRect (0, 0, getWidth(), getHeight());
g.setColor (0x00000000);
for (int i = 0; i)< line.length;="" i++)="">
g.drawString (line [i], 0, i * (Font.getDefaultFont () .getHeight () + 5), 20);
}

}

{} public void keyPressed (int code)
St += keyCode + ",";
splitStringToLines();
Repaint();
}

public void splitStringToLines() {}
int index = Font.getDefaultFont () .stringWidth (st) / getWidth();
        
If (Font.getDefaultFont () .stringWidth (st) % getWidth() > 0) {}
index ++;
}
        
row = new String [index];
for (int i = 0; i)< index;="" i++)="">
line [i] = "";
}
int i = 0;
pointer to int = 0;
Substring of String = "";
for (int j = 1; j)< st.length();="" j++)="">
            
Substring = st.substring (pointer, j);
System.out.println (SUBSTRING);
If (Font.getDefaultFont () .stringWidth (subString)< getwidth())="">
line [i] = substring;
                
} else {}
i ++ ;
pointer = j-1;
                
}
}
}
}

When you compile your midlet in the of Blackberry Java development environment , and then set the correct application type in the properties for the project.

Open project properties (click - menu "Properties" on the right project node).

Go to the "Application" tab and specify the type of project: MIDlet

and the full name (with the name of the package) to the main MIDlet class.

  • -error 60 on app install, nothing found so far helps. Please notify.

    Hello.

    Recently, I went to the creative cloud. Most of the time things are very good!

    However, whenever I try to install Audition or Flash Builder, I get the error of-60.

    I tried the update of all programs, used the cleanest, trying to turn off check the checksum in disk utility, uninstalled/reinstalled app CC, registered in and out, rebooted several times, with everything else I could find, but the error is still the same. I tried it works for about two days.

    Hearing goes to 8%, then I get the error-60. A new attempt will be go to 15, then 22, 30 and 38%. After this pressing the retry button immediately spits out the error-60. Flash builder goes to 2, 4 and finally stops pretending to download at around 8%, this behavior and these numbers are 100% reproducible.

    Acrobat Pro gave me the same question, but reboot resolved, and now it is functional.

    I'm on OSX 10.9, running a macbook from the retina of mid-2012.

    Any help will be greatly appreciated.

    Thank you in advance.

    According to specification specifications your machine was shipped with preinstalled Win8.1 64-bit so I m wondering what exactly you do.
    Please don't get me wrong you have the machine with the latest version of the OS, but now you have problems with the old version of the OS.

    Somehow, it is not logical for me.

    In any case, I ve tried to check the download page for your machine on http://www.toshibamea.com/en/Download-Files but anyway it doesn't work properly. I assume that there is only a temporary problem so I can't check what kind of stuff is listed for download.

    Hello

    It's funny you say that, because my friend has exactly the same problem as you! (but is not on a laptop, on a standard desktop configuration).

    When the service pack installs it checks for incompatible software during installation. What I would recommend would be to backup your data and install Service Pack 1 _directly_ after recovery of product and then install the 3 rd party software you want to install.

    (Especially the burning of programs/language packs being installed), I found that this has harmed the configuration causing the cancellation of the installation.

    If you give that to try and see what happens and if it doesn't work then come back and we can see what it can be.

  • Computer will not properly install update KB976098 + new software

    I was a lot by browsing this site and saw that many people is facing the same problem. What I did find was a person with software problems.

    My computer was purchased 26/11 this year with Windows 7 pro + Microsoft office home and student . One day Windows were 27 updates to install and therefore has been left overnight. In the morning update no. 27 was still install and never finished. Had to restart the computer to exit the update screen. days later there were 4 updates to install. Still once, the last update was never completed.

    Now, there's only 1 update important remaining, KB976098 , the fix for the time zones that I presume.

    Not only the update will not install, now the new software may not be installed properly:

    I tried some actions (such as downloading stuff, install software, games) while windows tried to install the
    Update:

    • During the installation (for example.) Adobe Reader, Comodo FireWall took more than a minute to display its notice of default on an attempt to install software on the computer and therefore compromised the initial installation.
    • Turn off Comodo Firewall does not solve the problem. Delay of the computer respond when an action of the instalation was performed is the same.
    • The installation of update process could not be stopped once he was "installation."
    • The icon of 'disable' had no notification "update", but once to close the office and displays the message "loging off", the computer is never extinguished.
    • While playing an online game, nothing unusual has happened, no delay on start-up or exit.
    • When you save things like a packadge power point (for conferences of 2007 to display on older versions) the application would freeze and the package has never been created
    • Presentations PowerPoint would have graphics errors, such as the black and white rectangles containing all movable objects.

    After Force-reboot of the computer, cancel the auto-update feature and remove it from the list self-install, I retested evevrything:

    • Adobe Reader has been installed successfully, even with Comodo Firewall active
    • Comodo Firewall has reacted instantly to any attempt installation
    • More online games the same
    • PowerPoint correctly displays images and created packages without error
    • Turn the computer off was possible without forcing the stoppage.

    Now, I'm checking the updates installed and found out there are only installed 23 (in the Control Panel installed updates ). The history of the update displays more than 74 update. As mentioned previously, the first batch of update contained 27 updates, No 23 or 24. I checked some of these updates to the story:

    • There are a few updates, eg. update of security for microsoft office system who have 10 diferent KBs (being the first of its kind, his last KB974234 KB936514). Five of them have been installed twice: KB936514; KB951944; KB954326; KB956828; KB960003

    I guess in these 74 updates, replacents occurred in 23 updates, and some are not microsoft partners to be included in the Panel of installed updates . I really don't know, that's why I am asking :D

    I tried the more possible ways to install the update, downloading it mannualy, disabling the firewall, close all other applications, etc. etc...

    I would like to know the following:

    1. Why is not install update KB976098?
    2. Why other users have the same problem with recent updates?
    3. How to prevent the installation of update if the stop command does not work?
    4. How can I turn off the computer without having to install the downloaded update?
    5. Are double downloaded updates a problem?

    I wrote this for so long now. If I forgot anything, the question might be already in the text.

    Thank you for your time and patience! :)

    Read the "Updates since the previous cumulative Windows time zone update" section of http://support.microsoft.com/kb/976098. If you do not reside in one of these 14 zones, really useless this not (IMHO) security-related update, so you can just "hide":

    1. stop the automatic updates service:

    Start > Right click on run , and then select run as administrator > services.msc (type) > [OK]

    2 remove the contents of the download folder:

    Start > Right click on run , and then select run as administrator >
    (type or copy/paste) %windir%\SoftwareDistribution > [OK]
    Open the download folder and delete its content
    Close the window.

    3 start | Control Panel | System maintenance and (if you use Classic view, skip this step). Windows Update: Select the installed updates: right click on the Update for Windows 7 (KB976098) | Click hide update | Confirm the prompt UAC (User Account Control), if any, & OK your way out.

    4. start the automatic updates service:

    Start > Right click on run , and then select run as administrator > services.msc (type) > [OK]
    Double-click automatic updates > click Start
    (Stopping the service will take a moment)

    =====================================
    To restore/show updates in Win7: Start | Control Panel | System maintenance and (if you use Classic view, skip this step) | Windows Update | Restore hidden updates: Find and select the update you want to install. Click restore. You can now select once again it and install through the normal process.
