[Huang Guan]

Dear All,

Roger, thanks for your patch, I have settled the fourth question
successfully.

Thanks Tim Roberts,Michel Clveau and Richard Bell gave much good
suggestions, which elicitation to resolve this question better.

Mhammond, thank you for leading to subscribe to python mail list, which is a
very good space for discussion.

I have to give my high honor to everyone of pywin32 team, it's you who
create the excellent win32 extend.

I hope would have more communion and direction in python mail list in the
future.

Thanks and best regards!
