前几天在我瑞星升级后,C盘里就老出现这个文件,里面的具体内容为:

  Attribute VB_Name = “GetLogicalDriveStringsEx“

  Option Explicit

  Private Declare Function GetLogicalDriveStrings Lib “kernel32“ Alias “GetLogicalDriveStringsA“ _

   (ByVal nBufferLength As Long, _

   ByVal lpBuffer As String) As Long

  Sub Get_Logical_Drive_String

  Attribute Get_Logical_Drive_String.VB_ProcData.VB_Invoke_Func = “ \n14“

   Dim DrvString As String

   Dim TotDrvs As Long

   Dim Counter As Integer

   ’TotDrvs returns the total number of characters in return string

   TotDrvs = GetLogicalDriveStrings(0, DrvString)

   ’DrvString is the buffer created to hold the string

   DrvString = String(TotDrvs - 1, “ “)

   ’Calling GetLogicalDriveStrings a second time fills the string with valid data

   ’example “a:\c:\d:\e:\“

   TotDrvs = GetLogicalDriveStrings(TotDrvs, DrvString)

   ’Parse through the return string displaying each in a msgbox

   For Counter = 1 To TotDrvs Step 4

   MsgBox Mid(DrvString, Counter, 3)

   Next Counter

  End Sub

   请教各位大虾这里面写的是什么东西啊?
