What dosn't work? Does the compiler/linker complain? Is an exception thrown? Do any replacements happen?

What does memory leak mean?

It's unnecessarily using memory when it is no longer needed and we didn't free it or the program doesn't free it.
Somethings seem HARD to do, until we know how to do them.

Basically its a bug in a program where memory cant be freed up (in my experience, it happend mostly with dynamically allocated memory cells). The program will continue taking up more and more memory until it eventually crashes:
a)Your computer
b)Your program
c)Your computer (You'll crash your computer into a wall once you realize that a program crashed windows and destroyed the 100 page thesis you were writing and didnt save :P)
Hope that helps

How does one know that a memory leak is happening? Or how does one find out where the memory keak is taking place?

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.

thnx for reply but both the dialog box are child dialo box.

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.

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