如果你觉得可以，把100分给我吧
我的方法很另类，给你说说过程
为了不重复文件名，我取时间为文件名filename
生成filename.script脚本，传输FTP用
生成filename.txt保存了combo1和text1的文字
调用ftp命令传输，不需要inet或winsock控件
API是SHELL WAIT功能，因为script脚本保存了帐号和密码，当传输完成后删除filename.script脚本
觉得如何，如果用inet不如这个简单，毕竟FTP不是自己写的，不管PASV与否都正常使用，唯一就是密码保存要等传输完成
你想的第一个方案是不可能的，FTP是文本传输协议，与HTTP不一样，不能写POST，实在想那样，VB做不了，需要手动创建数据包欺骗服务器

第一个按钮 上传
Dim filelast As String = fileaddbefore.Text.Substring(fileaddbefore.Text.LastIndexOf("."), fileaddbefore.Text.Length - fileaddbefore.Text.LastIndexOf("."))
MessageBox.Show(filelast)
My.Computer.Network.UploadFile(textbox1.Text, "" 文件名.Text filelast, "登录名1", "登录密码", True, 100)
