If (o1 == null | o2 == null)
throw new IllegalArgumentException ("can't compare countries null");
Return o1.toString () .compareTo (o2.toString ());

Thanks in advance...

Oky I solved the problem...

using the...

{if (g.isDrawingStyleSet (Graphics.DRAWSTYLE_FOCUS))}

change the accent color
g.setBackgroundColor (0xDCDCDC);
g.Clear ();
draw text
g.setFont (Resize.getSecondFont ());
g.setColor (Color.BLACK);
g.drawText (item.toString (), 20, y, DrawStyle.ELLIPSIS |) DrawStyle.HCENTER);

inside the drawListRow...

Thank you all...

    Please help me and I will be grateful


    Of course, you can change the operating system and install another I wonder what OS you prefer?  :|

    I think that you can not install the new OS because the HARD drive is not visible. Am I wrong?
    Fact is that the G20 series supports RAID functionality. You must install the RAID driver before you continue the OS installation procedure

    The RAID driver can be downloaded from the European pilot of Toshiba page and should be included in the operating system using an external USB FDD drive.


  • Satellite A210-128: I want to change the 320 GB HARD drive 7200 RPM

    Hallo all

    Can someoane help me with this little problem?
    I have a portable satellite A210-128 with a hard drive of 250 G 4200 RPM (* slowest *)... I want to change the hard drive with a hdd 2.5 "Western Digital 320 G 7200 RPM (* speed *).

    1. If I buy a disk sata2 hard can I put on my laptop because my A210-128 has a disk sata hard?

    2 can I I install vista on this new hard drive on my vista dvd, im asking this because I want to be shor that my recovery dvd * RECOGNIZES THE NEW HARD drive * and I can install a new copy of windows or installing dvd can * only works with disk drives hard toshiba *... ???

    Thank you.

    As to the question;

    (1) I think a SATA2 HARD drive would go because the standard SATA2 is compatible to the bottom. But I assume that the system will operate as a good HDD SATA.

    (2) Yes, you can install vista using the Toshiba Recovery DVD. It shouldn't be a problem with a fresh install
