Hi Wayne, George, Craig, Denis, Eric and Vlad,
>OK. I got it's stable.
>Now another question that comes to my mind :
>WinNT supports more API's than Win9x. When I have to write an API especially including net related work, how would I be sure the same routine would work on Win9x ? Of course I'd choose the API functions that are documented as supported both in Win9x and WinNT. Do you folks think it's enough ? Currently I do the reverse and have a feeling, "if that works under Win9x than works under WinNT". It has been a week W2000 RC2 reached my hands and I'm trying to make up my mind :) You great API experts should have a clearer idea :) TIA.

Hi Cetin,

I think it's probably enough. Your MSDN library can tell you the platform under requirements. Personally, however, I always install the latest Win SDK (Disc 6 of the Development Platform discs). The information is much easier to find.
