Download a file and then execute it
提问by user1970090
I'm creating an application that downloads some applications (like FireFox, WinRar, RealPlayer) and then install them silently using Shell command. This is the code:
我正在创建一个应用程序，用于下载一些应用程序（如 FireFox、WinRar、RealPlayer），然后使用 Shell 命令静默安装它们。这是代码：
My.Computer.Network.DownloadFile("URL", "path\file.exe")
Shell("path\file.exe /s")
The problem is that the shell command starts before Download Is completed, so I get a "file not found" error. So my questions are:
问题是 shell 命令在下载完成之前启动，所以我收到“找不到文件”错误。所以我的问题是：
- How can I execute Shell command after the download is completed?
- Can I use process.start with
Sparameter instead of Shell command?
- 下载完成后如何执行Shell命令？
- 我可以使用带有
S参数的process.start而不是 Shell 命令吗？

This should do the trick to download the file and wait until its over:
这应该可以下载文件并等待它结束：
Dim wc As WebClient = New WebClient()
wc.DownloadFile(sURL, sFile)
