UNLOCK PASSWORD PROTECTED MEMORY CARD

Well its quite simple but most of the people do not know it.

Please note the fact that it only works if the password to the MMC Card was set in ur own mobile,where u want it to be unlocked.

This method works well for nokia cells with symbian operating system.Never tried on other cells.use any software like FXplorer that can browse files in ur cell.

1. Open one of above software you have.
2. Browse through the directory, C:system
3. Rename the file mmcstore to mmcstore.txt
4. Open the file – The file will open in Notes.
5. You will find your password in that file. That file would also contain much more data which you do not understand,so you need to go through the file to get the password!

When ur cell is connected to pc by means of data cable or bluetooth,u can see the password by simply opening the file mmcstore with notepad.

Call ajax after completion of another ajax ,Wait for ajax to return.

Lets suppose you are trying to set loggedIn username to the header of your web page and you have 2 ajax which get fired

1st Ajax : Which is decorating the header

2nd Ajax : Which gets the username

So if 2nd AJAX become first in the race then username is not visible to you as 1st ajax is responsible for decorating the header and if there is no header there is no place where you can set header.

so to be very sure that our username is visible on the screen, we should wait for the header(1st ajax)to complete


document ready function:

$(document).ready(function () {

 //calling this method to get the fetch logged in user

 fetchloggeInUser();

});




1st Ajax request : run in parallel with 2nd ajax 

this is building our header part
(function ($) {
  $.pageDecorate = {
  //declare a global variable so that it can be used.
  decorateDeferred : null,
  //set response of the ajax in a variable
  var decoratorDeferred = $.ajax({
    url : 'setHeader',
    type : 'get',
    data : decorateHeaderData,
    dataType : 'json',
    success : function (data) {
     //response of testAjax sets in decorateDeferred
     decorateDeferred = $.pageDecorate.testAjax();
    }
   });


Global declaration :

  //set value of global variable decorateDeferred so
  // that it can be use as a reference

  $.pageDecorate.decorateDeferred = decorateDeferred;


  },


Method to call :
 testAjax : function () {

  var navHtml = '<ul>';
  navHtml += '<div class="divHeader" title="login">';
  navHtml += '<div class="role">';
  navHtml += '</div>';
  navHtml += '</div>';
  navHtml += '</ul>';
  //append this to header of your page
  $('.header').append(navHtml);
 }
});


2nd Ajax:

fetchloggeInUser : function () {

 $.ajax({

  url : "loggedInUser",

  type : "POST",

  success : function (data) {

   //although this success block call when ajax get 
   //fired but this code runs when it get response
   //after the success response of $.pageDecorate.decorateDeferred 
   this below success get called

   $.pageDecorate.decorateDeferred.success(function () {

    $('.divHeader').find('.role').text(userName);

   });

  }

 });

}



 That ‘s it you are done.
