Hi every one!
i am making a small application to on the camera Flash light for desire time.
but it is not working on my BB 8900.
i am new to develop so, please help me.
if any error and wrong way is in my code?

public class Screen_1 extends MainScreen{

HorizontalFieldManager Hrm;
Player p;
FlashControl flashControl;
CameraControl cameracontrol;
SnapshotControl snapcontrol;

public Screen_1() {


super();
LabelField mylabel=new LabelField("MY TOURCH",Field.USE_ALL_WIDTH);
setTitle(mylabel);
add(new RichTextField("Do you want, Flash light ON?"));





/* initializing the player */
try{
p= Manager.createPlayer("capture://video");
(Manager.MIDI_DEVICE_LOCATOR);
p.realize();
p.start();
}
catch(IOException me){Dialog.alert("IOException in NO:" + me);}
catch (MediaException me){Dialog.alert(" MediaException in NO: " + me);}


FieldChangeListener yesButton= new FieldChangeListener()
{
public void fieldChanged(Field field, int context)
{

flashControl= (FlashControl)p.getControl("javax.microedition.amm s.control.camera.FlashControl");


if(flashControl!=null)
{
try{
int test_mode =flashControl.getMode();
int test_support_mode[] = flashControl.getSupportedModes();
flashControl.setMode(FlashControl.FORCE);
int now_test_mode= flashControl.getMode();
Dialog.alert("yes button");
}
catch (IllegalArgumentException e){Dialog.alert("Illeglexception in yes:" + e);}
}

snapcontrol = (SnapshotControl)
p.getControl("javax.microedition.amms.control.came ra.SnapshotControl");


//for(;;)
snapcontrol.start(1);





}
};


ButtonField yesButtonField = new ButtonField("Yes");
ButtonField noButtonField = new ButtonField("No");
yesButtonField.setChangeListener(yesButton);
noButtonField.setChangeListener(noButton);
//add(yesButtonField);
//add(noButtonField);
add(new SeparatorField());
Hrm= new HorizontalFieldManager();
Hrm.add(yesButtonField);
Hrm.add(noButtonField);
add(Hrm);


}


}

hi
i am getting every thing is fine as i think,
but when it is executing the line
snapcontrol = (SnapshotControl)
p.getControl("javax.microedition.amms.control.came ra.SnapshotControl");
snapcontrol.start(1); // giving exception here??
i also tried with this
snapcontrol.start(Integer.MAX_VALUE);
but still exception.
can any one health how to over come this.
because i think when snapcontrol will start flash will give light.
Thanks and regards
