【VB声明】
Private Declare Function GetFileTime Lib "kernel32" Alias "GetFileTime" (ByVal hFile As Long, lpCreationTime As FILETIME, lpLastAccessTime As FILETIME, lpLastWriteTime As FILETIME) As Long
【说明】
取得指定文件的时间信息
【返回值】
Long,非零表示成功,零表示失败。会设置GetLastError
【备注】
如果不需要特定的信息,那么lpCreationTime,lpLastAccessTime,lpLastWriteTime都可以设置为零(用ByVal
As Long)。这个函数返回的文件时间采用UTC格式
【参数表】
hFile ---------- Long,文件的句柄
lpCreationTime - FILETIME,用于装载文件的创建时间
lpLastAccessTime - FILETIME,用于装载文件上一次访问的时间(FAT文件系统不支持这一特性)
lpLastWriteTime - FILETIME,用于装载文件上一次修改的时间
