what is the difference between these two statements
Statement ! : Dim obj as Emp
Statement 2 : Dim obj as New Emp
Emp is a Class with some member variables and member functions.

Dim obj as Emp :
This Statement dosen't allocate memory.It just creates a pointer on stack It osen't have address to work on memory since functions and data r available on stack.

Dim obj as New Emp :
This Statement allocates memory on heap.'obj' works as pointer when it accesses the functions on stack.These functions work on the data available on heap.
