Menghilangkan Service UI0Detect atau Internet Service Detection

UI0Detect merupakan service atau program yang ada di Windows 7, untuk apanya saya juga kurang tahu, yang pasti program ini sangan mengganggu saya pada saat itu. Entah apa yang sudah saya lakukan sama laptop saya, tiba2 program ini muncul terus menerus setiap menitnya. Dan pada akhirnya program ini berhasil saya ambil gambarnya saat dia muncul. Berikut gambarnya:

Program ini muncul setiap menit, dan sangat mengganggu, kenapa, karena dia mengalihkan fokus kursos pada proses yang sedang saya lakukan. Misalnya, saat saya sedang maen game Football Manager 2011 yang menggunakan layar full, maka aplikasi ini akan me-minimize-nya.

Setelah beberapa hari yang cukup lama saya belum menemukan apa sebenarnya program ini, akhirnya saya mendapatkan juga. Ya, program ini merupakan Internet Service Detection atau UI0Detect.

Dari beberapa sumber yang saya baca program ini bukan merupakan virus atau malware, programm ini merupakan sudah ada dalam instalan Windows 7. Dan ketika ingin menhapusnya, maka tidak akan ada masalah dengan proses windows 7.

Berikut adalah cara untuk menhilangkan aplikasinya:
1. Buka 'Control Panel'
2. Double click "Administrative Services"
3. Double-click "services"
4. Cari 'Internet Service Detection' pada kolom 'Name'
5. Pilih 'Stop'
6. Pilih lagi 'Internet Service Detection'  lalu klik kanan -> Properties
7. Pada 'Startup type', pilih ‘Disable’
8. Click “OK”
Selesai.

Validasi Email di Blackberry

Berikut adalah method untuk mengecek apakah email tersebut valid atau tidak, jika nilainya true maka valid dan sebaliknya.

public boolean isValidEmailAddress(String email) {

Custom EditField di Blackberry

EditField di Blackberry secara default di tampilkan dalam bentuk yang sangat kaku (mungkin ini pendapat pribadi saya), ia akan memakai semua width dari resolusi. Sehingga jika kita ingin menambah button di samping EditField maka button tersebut tidak akan tampil. Agar bisa tampil maka perlu untuk melakukan custom terhadap EditField tersebut.
Berikut code Custom EditField.

import net.rim.device.api.system.Characters;
import net.rim.device.api.system.Display;
import net.rim.device.api.ui.Color;
import net.rim.device.api.ui.Field;

        if(headingFont!=null){
            setFont(headingFont);
            graphics.drawText(label, 2, 10);
        }else{
            graphics.drawText(label, 2, 7);

        EditField ef = (EditField)getField(0);
        String entireText = ef.getText();
        
        boolean longText = false;
        String textToDraw = "";
        Font font = headingFont;
        int availableWidth = width - totalHorizontalEmptySpace;
        if (font.getAdvance(entireText) <= availableWidth)
        {
            textToDraw = entireText;
        }
        else
        {
            int endIndex = entireText.length();
            for (int beginIndex = 1; beginIndex < endIndex; beginIndex++)
            {
                textToDraw = entireText.substring(beginIndex);
                if (font.getAdvance(textToDraw) <= availableWidth)
                {
                    longText = true;
                    break;
                }
            }
        }
        
        if (longText == true)
        {        
            ef.setText(textToDraw);          
            super.paint(graphics); 
            ef.setText(entireText);
        }
        else
        {
            super.paint(graphics);
        }
         
    }
     
    public int getPreferredWidth(){
        return width;
    }
     
    public int getPreferredHeight(){
        return height;
    }
     
    protected boolean keyChar(char ch, int status, int time){        
       if (ch == Characters.ENTER)
       {
            return true;
       }     
       else
       {
            return super.keyChar(ch, status, time);
       }
    } 
   
    protected void onUnfocus() {
       super.onUnfocus();
    }
   
    protected void onFocus(int direction) {
       super.onFocus(direction);
    }
  
    protected void drawFocus(Graphics graphics, boolean on) {
       super.drawFocus(graphics, on);
    }

    public String getText(){
       return ((EditField) getField(0)).getText();
    }
         
    public void setText(final String text){
       ((EditField)getField(0)).setText(text);
    }  
}

Sekarang Tambahkan Code berikut di MainScreen untuk menampilkan TextFieldCustom.

   LabelField nama = new LabelField("Nama: ");        
   TextFieldCustom textField = new TextFieldCustom();
   ButtonField namaBtn = new ButtonField("OK");
        
   HorizontalFieldManager hfm = new HorizontalFieldManager();
   hfm.add(nama);
   hfm.add(textField);
   hfm.add(namaBtn);
   add(hfm);
