Functions within a Dll

Hi
Inorder to use functions of a dll you must know the parameters, if you do not have the function proto in some header file then you should find out the parameters by debugging and/or disassembling the dll, reading the code will help to find the number of parameters and what they should be while passing to the function. a useful hint is to look at the return point of the function, there should be some ADD esp,n where n maybe the number of bytes pushed into stack before calling the function, and n is a multiple of 4.

Thanks

light shadow is perfectly right, the dll exposes a decryption (encryption too?) routine for the sql server password.
So I think this is not what you were looking for.
I would go a bit OffTopic if I suggested you some other sources for enc/dec routines, so I stop here, but if you need something about this topic, just call me back
