我是在网上找到一个将数据存到Excel表格中的类，然后经过自己修改使用的。
我把这个类存成Excel.inc文件。
Excel.inc

If iColOff > 0 then
iColOffset = iColOff
Else
iColOffset = 2
End If
End Property
Public Property Let RowOffset(iRowOff)
If iRowOff > 0 then
iRowOffset = iRowOff
Else
iRowOffset = 2
End If
End Property

s_Str = "VIP模式（无延时）"
Else

下面是调用这个类文件的过程：

我的注释写的不是特别的清楚，如有不懂的可以跟贴。
