如何实现遍历文件夹中的所有文件 

　　办法如下：
　
　　把下面放到模块中


Option Explicit 

Public Declare Function FindFirstFile Lib "kernel32" Alias "FindFirstFileA" _
(ByVal lpFileName As String, lpFindFileData As WIN32_FIND_DATA) As Long
Public Declare Function FindNextFile Lib "kernel32" Alias "FindNextFileA" _
(ByVal hFindFile As Long, lpFindFileData As WIN32_FIND_DATA) As Long
Public Declare Function FindClose Lib "kernel32" (ByVal hFindFile As Long) As Long

Public Const MAX_PATH = 260
Public Const FILE_ATTRIBUTE_ARCHIVE = &H20
Public Const FILE_ATTRIBUTE_COMPRESSED = &H800
Public Const FILE_ATTRIBUTE_DIRECTORY = &H10
Public Const FILE_ATTRIBUTE_HIDDEN = &H2
Public Const FILE_ATTRIBUTE_NORMAL = &H80
Public Const FILE_ATTRIBUTE_READONLY = &H1
Public Const FILE_ATTRIBUTE_SYSTEM = &H4
Public Const FILE_ATTRIBUTE_TEMPORARY = &H100

＇自定义数据类型FILETIME和WIN32_FIND_DATA的定义
Public Type FILETIME
　dwLowDateTime As Long
　dwHighDateTime As Long
End Type

Public Type WIN32_FIND_DATA
　dwFileAttributes As Long
　ftCreationTime As FILETIME
　ftLastAccessTime As FILETIME
　ftLastWriteTime As FILETIME
　nFileSizeHigh As Long
　nFileSizeLow As Long
　dwReserved0 As Long
　dwReserved1 As Long
　cFileName As String * MAX_PATH
　cAlternate As String * 14
End Type
