我在很久以前就实现了这个方法了。它没有采用任何的控件形式,也没有调用系统API函数FindFirst,FindNext进行递归调用,和别人有点不同的就是我用的是VB中的Dir()函数。事实上,直接采用Dir()函数是不能进行自身的递归的调用的,但我们可以采用一种办法把Dir将当前搜索目录的子目录给保存下来,然后在自身的search(strPathName)递归函数中依次进行递归的调用,这样就可以把指定的目录搜索完毕。 具体代码如下: ''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' '函数GetExtName '功能:得到文件后缀名(扩展名) '输入:文件名 '输出:文件后缀名(扩展名) ''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' Public Function GetExtName(strFileName As String) As String Dim strTmp As String Dim strByte As String Dim i As Long For i = Len(strFileName) To 1 Step -1 strByte = Mid(strFileName, i, 1) If strByte <> "." Then strTmp = strByte + strTmp Else Exit For End If Next i GetExtName = strTmp End Function Public Function search(ByVal strPath As String, Optional strSearch As String = "") As Boolean Dim strFileDir() As String Dim strFile As String Dim i As Long Dim lDirCount As Long On Error GoTo MyErr If Right(strPath, 1) <> "\" Then strPath = strPath + "\" strFile = Dir(strPath, vbDirectory Or vbHidden Or vbNormal Or vbReadOnly) While strFile <> "" '搜索当前目录 DoEvents If (GetAttr(strPath + strFile) And vbDirectory) = vbDirectory Then '如果找到的是目录 If strFile <> "." And strFile <> ".." Then '排除掉父目录(..)和当前目录(.) lDirCount = lDirCount + 1 '将目录数增1 ReDim Preserve strFileDir(lDirCount) As String strFileDir(lDirCount - 1) = strFile '用动态数组保存当前目录名 End If Else If strSearch = "" Then Form1.List1.AddItem strPath + strFile ElseIf LCase(GetExtName(strPath + strFile)) = LCase(GetExtName(strSearch)) Then '满足搜索条件,则处理该文件 Form1.List1.AddItem strPath + strFile '将文件全名保存至列表框List1中 |
