I am puzzled by this problem for a long time:
.NET EXE and DLL files both have address space. I know that they both have code space and global variable space. But I want to know whether DLLs have their own heap and stack space.

DLLs cannot have stack space, as they do not have threads. Code executed from a DLL is run within the context of the calling process, and on that process's thread, thus localizing the memory allocation to your application, not the DLL. – Cody Gray - on strike Apr 17 '11 at 09:34

@cody of course a DLL could create a thread – David Heffernan Apr 17 '11 at 09:38

The process owns the heap. Each thread owns its own stack. When an EXE calls a function in a DLL the same stack is used because the function call is within the same thread.
The other point to make is that the process has the address space into which the EXE and DLL are loaded.

AFAIK,
EXE:
- Its a executable file.
- When a system launches new exe, a new process is created
DLL
- Its a Dynamic Link Library.
