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
My.Computer.Network.UploadFile
比如上传到FTP
My.Computer.Network.UploadFile("d:\1.txt", "“, "FTP账号", "FTP密码", True, 100)
新手路过。
Dim OpenFileDialog As New OpenFileDialog
OpenFileDialog.InitialDirectory = My.Computer.FileSystem.SpecialDirectories.MyDocuments
OpenFileDialog.Filter = "文本文件(*.jpg)|*.jpg|所有文件(*.*)|*.*"
If (OpenFileDialog.ShowDialog(Me) = System.Windows.Forms.DialogResult.OK) Then
Dim FileName As String = OpenFileDialog.FileName
' TODO: 在此处添加打开文件的代码。
textbox1.Text = FileName
End If
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)
第二个按钮
用script脚本 直接调用 FTP 命令实现上传文件到FTP服务器。
代码如下：

Print #1, upin
Print #1, "pwd"

pHnd = OpenProcess(SYNCHRONIZE, 0, pId)
If pHnd 0 Then
Call WaitForSingleObject(pHnd, INFINITE)

1、实现上传按钮方法代码。
2、判断图片对象是否为空代码。
3、取得数据库字段 dt.Rows(0)("Pic")方法代码。
4、字节数组转换为Image类型方法代码。
5、处理SQL中操作Image类型方法代码。
6、实现的上传结果。
