        db=new databse(this);
        
        db.database();
        bt.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View arg0) {
				db.open();
				byte[] p=db.getpic(Integer.parseInt(et.getText().toString()));
				if(p!=null){
				Bitmap bm=BitmapFactory.decodeByteArray(p, 0, p.length);
				ie.setImageBitmap(bm);
				
				}else{
					
				}
