A memory leak is caused when an area of memory no longer has any pointers pointing to it, but it has not been freed. For example:
int *ptr = new int[10];
ptr = new int[5]; The second allocation causes a memory leak, because the memory allocated in the first line cannot be reference, but has not been freed. There is no way you can go back and reference the first memory block, so it has been "leaked".

What is the best way to communicate between Threads?

threads share the same memory amounts, so there no need to build communication between them (such as pipe, locked tmp files, etc...).

PostThreadMessage or SendMessageTimeout according to your ease.

What's the best way to build a house? 
There are many ways, ranging from thread messages (PostThreadMessage etc...) through shared memory, mailslots, pipes and shared variables (with appropriate mutexes/critical sections). Read up on them all and pick the one most suited to your application.

i am using a dialog based mfc win app. how can i retrive the value of the edit box in the cpp of another dialog box.

You can use GetParent() and from the pointer returned from this function access the edit box contents in another dialog.
Somethings seem HARD to do, until we know how to do them.

Still you can move on with the same procedure.
Another method is that say you have two classes CFirst and CSecond associated to the two dialogs. Then you can declare a pointer of the CFirst class in the CSecond class and then access the variable in the CSecond class.
Ex: When you are calling the second dialog
CSecond* mySecond=new CSecond();
mySecond->myFirst=this;
mySecond->DoModal(); // ShowWindow with Create if modeless dialog.
In the header file of CSecond dialog declare
CFirst *myFirst;
// DO not forget to include header files for both dialogs respectively.
Somethings seem HARD to do, until we know how to do them.

mySecond->myFirst=this;
in this line it is showing type conversion error.

I think that you are creating the pointer in Second.h for the class CSecond itself.Check this out.
// Include Second.h in the file where you are calling this code.
CSecond *mySecond=new CSecond ();
mySecond->myFirst =this;
mySecond->DoModal ();
Open the Second.h file and in the public section declare a pointer as
// Include the header file for First.h
CFirst* myFirst;
// Delete the memory occupied to prevent memory leeks.
Somethings seem HARD to do, until we know how to do them.
