Thank you Remy

Where the shoe pinches is that the object in the DLL can't be operated 
normally

for example, a abstract class(Base) declared in the DLL and class Derive 
inherited from it, the Derive class is instantiated when the DLL has been 
Loaded and the EXE write can get a Base class pointer point to the Derive 
object via the export function of the DLL, but I can't access the data 
member and some virtual function

i.e.
1. can't access data member
a int variant has been initialized with 0 in the constructor of the Derive, 
but when I access it in a member function, I found the value has changed, so 
I print the address of that variant, it's actually difference in the 
constructor and member function, why?

2. virtual function that add to the Derive can't be invoked
the program show a error message when the virtual function is been invoking.

Any hint?

sorry for my poor English, if you don't understand the question, I'll try to 
descript it again.
