Dir[(pathname[,attributes])]
Dir 函数的语法具有以下几个部分:
以 vbDirectory 属性来调用 Dir 不能连续地返回子目录。!!!
以下是VB帮助自带查目录的例子,明确的指出目录必须要用GetAttr!!!
' 显示 C:\ 目录下的名称。
MyPath = "c:\" ' 指定路径。
MyName = Dir(MyPath,vbDirectory) ' 找寻第一项。
Do While MyName <> "" ' 开始循环。
' 跳过当前的目录及上层目录。
If MyName <> "." And MyName <> ".." Then
' 使用位比较来确定 MyName 代表一目录。
If (GetAttr(MyPath & MyName) And vbDirectory) = vbDirectory Then
Debug.Print MyName ' 如果它是一个目录,将其名称显示出来。
End If
End If
MyName = Dir ' 查找下一个目录。
Loop
