When EXE & DLL have different memory managments, if you malloc memory at DLL 
and free it at EXE, the heaps get mixed and you get an exception. I can 
understand that. when i read GlobalAlloc/GlobalFree documentation, it says 
that those functions are using default heap (means GetProcessHeap()). So, 
when i create memory with GloballAlloc in DLL and GlobalFree it in EXE, it 
does not give an exception ? GetProcessHeap()  returns the same value in DLL 
& EXE. is that mean the heaps are same ? if the heaps are same, why 
malloc/free giving an error ? does not malloc/free using GlobalAlloc or 
HeapAlloc ? thanks for helping...

P.S. : GMEM_FIXED param. used to create memory with GlobalAlloc.
