1.我想问问,rnd函数
如 :a=10
b=int (a*rnd+1)
c=int (a*rnd+1)
msgbox b & "*****" & c
为什么b,c第一次总取b=8,c=62.如何copy几个文件到一个地方,(copyfile 如何列出几个文件)
如 :a=10
b=int (a*rnd+1)
c=int (a*rnd+1)
msgbox b & "*****" & c

c=int (a*rnd+1)
b = Int(a * Rnd(a) + 1)
c = Int(a * Rnd(a) + 1)
MsgBox b & "*****" & c
不是呀,我想 f:\aa.txt,bb.txt,cc.txt copy 到 d:\aa.txt
how to ???
