我的任务
分享如何使用Internet Transfer控件获取FTP服务器上某文件的修改时间？
我想使下载到本地的文件与FTP服务器上的文件的修改时间一致，但使用"GET"获取的文件的修改时间为下载时间，请问如何获取FTP服务器上某文件的修改时间？谢谢了！

：rainstormmaster(暴风雨 v2.0)：你好，谢谢你的帮助。我是用Inet API函数来做的，使用FtpFindFirstFile来获取相关信息，其中包含文件的修改时间。

//我用remotehelp看了一下，远程主机不支持modtime命令啊。我用程序时间操作的时候，操作结果一直不能返回。
即使你的远程主机支持modtime命令，得到文件最后修改时间也要费很多事，在写ftp程序的时候，用winsock是最好的，不过对你的要求也是最高的

GetHeader 方法只能用于HTTP协议。

用API函数或者winsock都可以
Internet Transfer Control再试试

用API函数倒是可以实现，我用VB的目的就是为了使用Internet Transfer Control使问题简单一些，要是使用API的话我干脆用VC做算了。

呵呵，对ftp命令不熟吧：
FTP命令是Internet用户使用最频繁的命令之一,不论是在DOS还是UNIX操作
系统下使用FTP,都会遇到大量的FTP内部命令,熟悉并灵活应用FTP的内部命令,可
以大大方便使用者,对于现在拨号上网的用户，如果ISP提供了shell可以使用noh
up，那么ftp将是你最省钱的上download方式，
ftp的命令行格式为:ftp －v －d －i －n －g[主机名]
－v 显示远程服务器的所有响应信息。
－d 使用调试方式。
－n 限制ftp的自动登录,即不使用.netrc文件。
－g 取消全局文件名。
ftp使用的内部命令如下(其中括号表示可选项):
1.![cmd[args]在本地机中执行交互shell、exit回到ftp环境,如!ls＊.zip 。
2.￥ macro－ame[args]执行宏定义macro－name。
3.account[password]提供登录远程系统成功后访问系统资源所需的补充口令 。
4.appendlocal－file[remote－file]将本地文件追加到远程系统主机,若未指定远程系统文件名,则使用本地文件名。
5.ascii 使用ascii类型传输方式。
6.bell每个命令执行完毕后计算机响铃一次。
7.bin使用二进制文件传输方式。
8.bye退出ftp会话过程。
9.case在使用mget时,将远程主机文件名中的大写转为小写字母。
10.cd remote－dir 进入远程主机目录。
11.cdup进入远程主机目录的父目录。
12.chmod modefile－name将远程主机文件file－name的存取方式设置为mode,如chmod 777 a.out。
13.close中断与远程服务器的ftp会话(与open对应)。
14.cr使用asscii方式传输文件时,将回车换行转换为回行。
15.delete remote－file删除远程主机文件。
16.debug[debug－value]设置调试方式,显示发送至远程主机的每条命令,如debup3,若 设为0,表示取消debug。
17.dir[remote－dir][local－file]显示远程主机目录,并将结果存入local－file。
18.disconnection同close。
19.form format将文件传输方式设置为format,缺省为file方式。
20.getremote－file[local－file]将远程主机的文件remote－file传至本地硬盘的local－file。
21.glob设置mdelete、mget、mput的文件名扩展,缺省时不扩展文件名,同命令行的－g参数。
22.hash每传输1024字节,显示一个hash符号(＃)。
23.help[cmd]显示ftp内部命令cmd的帮助信息,如help get。
24.idle[seconds]将远程服务器的休眠计时器设为[seconds]秒。
25.image设置二进制传输方式(同binary)
26.lcd[dir]将本地工作目录切换至dir。
27.ls[remote－dir][local－file]显示远程目录remote－dir,并存入本地local－file。
28.macdef macro－name定义一个宏,遇到macdef下的空行时,宏定义结束。
29.mdelete[remote－file]删除远程主机文件。
30.mdir remote－files local－file与dir类似,但可指定多个远程文件,如mdir＊.o.＊. zipoutfile。
31.mget remote－files传输多个远程文件。
32.mkdir dir－name 在远程主机中建一目录。
33.mls remote－file local－file同nlist,但可指定多个文件名。
34.mode[mode－name]将文件传输方式设置为mode－name,缺省为stream方式。
35.modtime file－name显示远程主机文件的最后修改时间。
36.mput local－file将多个文件传输至远程主机。
37.newerfile－name如果远程机中file－name的修改时间比本地硬盘同名文件的时间更近,则重传该文件。
38.nlist[remote－dir][local－file]显示远程主机目录的文件清单,并存入本地硬盘的local－file。
39.nmap[inpatternoutpattern]设置文件名映射机制,使得文件传输时,文件中的某些字符相互转换,
如nmap￥1.￥2.￥3[￥1,￥2].[￥2,￥3],则传输文件a1 .a2.a3时,文件名变为a1、a2，
该命令特别适用于远程主机为非U－NIX机的情况。
40.ntrans[inchars[outchars]设置文件名字符的翻译机制,如ntrans1R,则文件名LL L将变为RRR。
41.open host[port]建立指定ftp服务器连接,可指定连接端口。
42.passive进入被动传输方式。
43.prompt设置多个文件传输时的交互提示。
44.proxyftp－cmd在次要控制连接中,执行一条ftp命令,该命令允许连接两个ftp服务器,以在两个服务器间传输文件。
第一条ftp命令必须为open,以首先建立两个服务器间的连接。
45.put local－file[remote－file]将本地文件local－file传送至远程主机。
46.pwd显示远程主机的当前工作目录。
47.quit同bye,退出ftp会话。
48.quote arg1,arg2……将参数逐字发至远程ftp服务器,如quote syst。
49.recv remote－file[local－file]同get。
50.regetremote－file[local－file]类似于get,但若local－file存在,则从上次传输中断处续传。
51.rhelp[cmd－name]请求获得远程主机的帮助。
52.rstatus[file－name]若未指定文件名,则显示远程主机的状态,否则显示文件状态。
53.rename[from][to]更改远程主机文件名。
54.reset清除回答队列。
55.restart marker从指定的标志marker处,重新开始get或put,如restart 130。
56.rmdir dir－name删除远程主机目录。
57.runique设置文件名唯一性存储,若文件存在,则在原文件后加后缀。
58.send local－file[remote－file]同put。
59.sendport设置PORT命令的使用。
60.site arg1,arg2……将参数作为SITE命令逐字发送至远程ftp主机。
61.size file－name显示远程主机文件大小,如site idle 7200。
62.status显示当前ftp状态。
63.struct[struct－name]将文件传输结构设置为struct－name,缺省时使用stream结构。
64.sunique将远程主机文件名存储设置为唯一(与runique对应)。
65.system显示远程主机的操作系统类型。
66.tenex将文件传输类型设置为TENEX机所需的类型。
67.tick设置传输时的字节计数器。
68.trace设置包跟踪。
69.type[type－name]设置文件传输类型为type－name,缺省为ascii,如typebinary,设置 二进制传输方式。
70.umask[newmask]将远程服务器的缺省umask设置为newmask,如umask 3。
71.useruser－name[password][account]向远程主机表明自己的身份,需要口令时,必须输入口令,如user anonymous my@email。
72.verbose同命令行的－v参数,即设置详尽报告方式,ftp服务器的所有响应都将显示给用户,缺省为on.
73.?[cmd]同help。
