mlCounter=Application("giCounter")
maChats=Application("gaChats")
如果写入的行数超过10,则重新开始记数.
if mlCoundter＞9 then
mlCoundter=0
end if
增加用户的输入,计数器加1
maChat(mlChounter)=Session("ssWho")&":"&Request("txtCents")
mlCounter=mlCounter+1
把局部变量设置为在应用范围内有效.
Applicati "giCounter")=mlCounter
Application("gaChats")=maChat
消除Application对象的封锁
Application.Unlock
end if
