How to display the Image on the screen.

I was New in aid of BB.Plz.

I am facing the problem is, I go get web Image.

But how do I show on the extraction of Screen.For that I write code like this,

If there's a problem with this code, then how may - I, please Hepl me out.

import java. IO;
Javax.microedition.io import. *;
Net.rim.device.api.ui.component import. *;
Net.rim.device.api.ui.container import. *;
Net.rim.device.api.ui import. *;
Javax.microedition.lcdui import. *;
Javax.microedition.midlet import. *;

showImage class extends FieldChangeListener implements screen
{
ButtonField down;
Image img;
ImageItem IM/it;
public showImage()
{
LabelField title = new LabelField ("Image Download Example", LabelField.ELLIPSIS |) LabelField.USE_ALL_WIDTH);
setTitle (title);
down = new ButtonField ("Download");
down.setChangeListener (this);
Add (Down);
       
}
    
Public Image startImage()
{
String url = "http://media1.santabanta.com/full4/bikes/triumph/triumph-20d.jpg";
HttpConnection hc = null;
DataInputStream tell = null;
Try
{
HC = (HttpConnection) Connector.Open (URL);
hc.setRequestMethod (HttpConnection.GET);
int st = hc.getResponseCode ();
if(St==HttpConnection.HTTP_OK)
{
int len = (int) hc.getLength ();
System.out.println ("==> Code" + hc.getResponseCode ());
System.out.println ("Message ==>" + hc.getResponseMessage ());
BTS Byte = new byte [len];
tell = new DataInputStream (hc.openInputStream ());
dis.readFully (bts);
IMG = image.createImage (BTS, 0, Len);
tell. Close();
HC. Close();

}

} catch (Exception e) {}
return img;
}
' Public Sub fieldChanged (field f, int c)
{
if(f==Down)
{
Image image = startImage ();
Add (image);
}
}
}

Take a look at these classes:

import net.rim.device.api.system.Bitmap;
import net.rim.device.api.system.EncodedImage;
import net.rim.device.api.ui.image.Image;
import net.rim.device.api.ui.component.BitmapField;

This code should do you need:

        EncodedImage image = EncodedImage.createEncodedImage(data, offset, length);
        BitmapField bitmapField = new BitmapField();
        bitmapField.setImage(image);
        add(bitmapField);

    There may be a solution on how to split the screen into two (halves) for independent display

    through the use of third-party software options. I haven't tried everything, but have read of some who can work.

    Such a "solution party' appears in the Mac App Store; See the second link to the manufacturer.

    The ability to rotate the screen image is a characteristic of your video
    card, to help work with instructors who turn to the portrait
    orientation. Almost certainly you accidentally pressed Ctrl-Alt, and
    an arrow key.
    Rotate using these keys.

  • How to display the date on the taskbar (toolbar)

    Please tell me how to display the date at the bottom of the screen.  Currently, everything is displayed is the time.

    Hello

    You said in addition to the clock so I initially think not that you need it however, others said it would be a good idea to show this method of date display. Also if you move the taskbar vertically the date is also displayed.

    Always see the day, date and time in the taskbar
    http://freewindowsvistatutorials.com/meetWindowsVista/taskbarAndSystemTray/showDayDateAndTimeInTheClock.php

    You can lift the taskbar is higher - make a right click on it - uncheck box lock the taskbar then take the upper part of it and lift it higher and the date will be under the clock.

    --------------------------------------------------------------------

    I found a utility that does on one level of the bar tasks if it does not have to be raised-

    Hi there @antonio55,

    That the Forums are with you!  I understand that you are looking for advice on how to clean your screen.  I'm happy to give you a helping hand with this.

    Please see: HP monitors - Safety and Maintenance Guidelines, under the heading "Cleaning the monitor" for details of cleaning, but be sure to read both safety related information.  Depending on what you mean by "halos" try following the instructions for the materials to be used. If you have in the past used something on the list of cleaning products do not turn out to serve, you may have already damaged a part of the screen.

    Please let me know if it works for you and if it does not solve your problem, please mark this message as a solution. Bravo would be appreciated as well.

  • How to replace the screen & HDD in Tecra S1

    2. bad drive c. message is 992 KB bad clusters. How to replace or repair the C drive?
    Thank you

    Hello

    Well, the replacement of HARD disk drive is very easy on the Tecra S1.
    At the bottom of the unit, you will find a cover that protects the HARD drive Bay.
    A screw covers. Remove it.
    Then, it should be possible to remove the HARD drive.

    The replacement of the screen is another matter. It is not easy to remove it. In this case I recommend to contact Toshiba service in your country for details.

    Hello

    I need help to change the screen on a Satellite L30 - 11 d. I accidentally pressed the screen that has a large black spot on him.

    Everything can show me how to change the screen with a new one please?

    Hello

    Unfortunately, you won't find manuals or on the pages of Toshiba disassembly instructions.
    I think that these instructions are made for service technicians only and are not for public use

    In any case, I think there is a lot of information on the internet and I think if you really need this info, then you should google a bit.
    But once again; It s always best to ask a technician for aid of the disassembly procedure is complicated and there is a high risk of damage this part.
    In the worst cases, damage another essential element which would be too expensive.

  • How to display the list of components in ultiboard 10?

    The DRC report the errors where the components that are no longer in the design have been removed. How to display the list component and then remove them from the netlist to stop this?

    Ultiboard reported missing errors of component (part 'X' is not about design) because the part is always referenced by a net. To fix this, you must remove the part of the net. Following the steps below to remove the part form the net.

    1 tools > Netlist Editor

    2. for each network that the part has been connected to, select the Net (upper-left).

    3. Select the tab of pine trees, select the part and it is the PIN in the dialog box, then click on remove

    The problem is when the part is removed, I see no easy way to determine the threads you need to remove the part of. I entered this as a feature request to make this easier, but as a workaround, you can put part and say Ultiboard what the missing part, then search the net names on the pins and remove the part of these pins

    1 place a piece with a lot of pine trees (for example the part that was removed, or for example through Hole technology > Connectors > SIL & headers > HEADER2X9). When you place the part, make sure that the RefDes matches the RefDes of the part which has been removed.

    2. once the room is placed, you should see rats nest lines that connect the part to the nets.

    3 Zoom on the pins. You should now see the net name on each of the axes. For each of the pins connected, remove it from the net as described above.

    4. remove the part that you placed.
