java - problem in moving data's from one page to the other in android -

-

I have three activities named as A, B and C, as in the activity, there is some data like name I

Date of B. in activity and activity. Now in Activity C, I want to display those names and date of birth. I tried to use the steps given in the following link

I am able to move from activity B to C, but data stored in Activity A is not visible

The following is the code that I have placed in Activity A 

  myIntent = new intent (getBaseContext (), UserInformation.class); MyIntent.putExtra ("i1", name); MyIntent.putExtra ("i2", add); StartActivityForResult (myIntent, 0);   
 The following is the activity that I have used in Activity B  
  myIntent = new intent (getBaseContext (), UserManual.class); MyIntent.putExtra ("i3", regno); MyIntent.putExtra ("i4", dob); StartActivityForResult (myIntent, 0);   
 The following is the activity that I have used in Activity C  
  @Orride Create a public void form (bundle saved instenstate) {super.onCreate (savedInstanceState ); `Bundle Extras = Milentant (). GetExtras (); String i1 = extras.getString ("i1"); String i2 = extras.getString ("i2"); String i3 = extras .getString ("i3"); String I4 = extras.getString ("i4"); If ((i1! = Null) & amp; (i2! = Null)) {s = i1 + i2; Extras.Puncerequence ("S", S); } If ((i3! = Null) & amp; (i4! = Null)) {b = i3 + i4; Extra.Power Sequence ("B", B); }}   
 I have separate text views for both.  
 Pls explain to me what is my error ...   
 
 
 OK, We think that the matter is being looked at: A-> B-> C Now Code: Activity B:  
  Bundles Extra = getIntent (). GetExtras (); String i1 = extras.getString ("i1"); String i2 = extras.getString ("i2"); MyIntent = new intent (getBaseContext (), UserManual.class); MyIntent.putExtra ("i1", i1); MyIntent.putExtra ("i2", i2); MyIntent.putExtra ("i3", regno); MyIntent.putExtra ("i4", dob); StartActivityForResult (myIntent, 0); Therefore, a passing value for activity activity B and then Activity B will pass all values ​​to activity C: :)

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow?
