5、CompareFileTime
function ulong CompareFileTime( REF s_filetime lpFileTime1, REF s_filetime lpFileTime2) library "kernel32.dll" Alias for "CompareFileTime"
| VB声明 |
| Declare Function CompareFileTime Lib "kernel32" Alias "CompareFileTime" (lpFileTime1 As FILETIME, lpFileTime2 As FILETIME) As Long |
| 说明 |
| 根据FILETIME结构的信息，对比两个文件的时间 |
| 返回值 |
| Long，如两个时间相等，就返回零；如lpFileTime1小于lpFileTime2，返回-1；如lpFileTime2小于lpFileTime1，返回1 |
| 参数表 |
| 参数 |
类型及说明 |
| lpFileTime1 |
FILETIME，参考FILETIME |
| lpFileTime2 |
6、CopyFileA function ulong CopyFileA(string lpExistingFileName, string lpNewFileName, long bFailIfExists) library "kernel32.dll" Alias for "CopyFileA"
| VB声明 |
| Declare Function CopyFile Lib "kernel32" Alias "CopyFileA" (ByVal lpExistingFileName As String, ByVal lpNewFileName As String, ByVal bFailIfExists As Long) As Long |
| 说明 |
| 复制文件。与vb的filecopy命令相似 |
| 返回值 |
| Long，非零表示成功，零表示失败。会设置GetLastError |
| 参数表 |
| 参数 |
类型及说明 |
| lpExistingFileName |
String，源文件名 |
| lpNewFileName |
String，目标文件名 |
| bFailIfExists |
Long，如果设为TRUE（非零），那么一旦目标文件已经存在，则函数调用会失败。否则目标文件被改写 | |
