thanks for any help,

can you create a small sample to reproduce the error?
the only problem i know of is wchar_t related - you cannot use /zc:wchar_t+ with dd (due to vc8 compiler bug).
but i didn't checked if it is true for vc8 sp1, perhapt they fixed it.

thanks for the reply but i have figured out a solution. i must do my includes before "using namespace system;". i do not know exactly why that helps, but it does. also, i can confirm that the /zc:wchar_t+ bug is still in sp1.
