我目前正在使用以下代码dos从VBA.
Set objShell = CreateObject("WScript.Shell")
dos_command="\\\10.xx.xx.xx\test\7z.exe a -r " etc etc etc
result = objShell.Run(dos_command, 0, True)
Set objShell =nothing
一切运行良好，唯一的问题是我收到一个烦人的警告 Windows 框，建议程序试图在我的计算机上运行，按 OK 或 Cancel
我必须使用"objshell"，因为我需要VBA等到DOS命令完成。
有没有办法避免警告框从 VBA 中出现或向 DOS 命令添加一些附加参数？
7z.exe 文件在服务器（不是本地 PC）中运行，所以我认为这就是问题所在。
我无法在每台机器上使用或安装 7z.exe。
以下是三个选项，按从最快/最脏到最强大的顺序排列：
创建一个文本文件作为命令行的一部分并等待它的存在：将您的命令行修改为类似的内容并使用Shell（不是您的objShell）运行它：
dos_command = "\\\10.xx.xx.xx\test\7z.exe a -r " etc etc etc
dos_command = dos_command & " && echo > " & TempFileName
这将创建一个以您的 7-zip 编码完成TempFileName 命名的文本文件。您只需要在运行 shell 命令之前确保TempFileName不存在，然后运行命令并等待TempFileName文件存在。
使用OpenProcess和GetExitCodeProcessAPI ：使用OpenProcess API 调用启动命令行，该调用提供对新进程的访问（请注意，该Shell函数返回已启动进程的 ProcessID）。然后使用 ProcessID 进入循环并通过GetExitCodeProcess轮询进程。相关声明：

' Procedure : ShellWait
' DateTime : 2/15/2008 10:59
' Author : Mike
' Purpose : Executes a shell command and waits for it to complete.
' Notes : Runs the shell as a batch file, allowing the user to pass a string with
' line breaks to execute a multi-line command.
'
' : Provides two means to break out of the loop.
' 1) Provide a timeout in seconds.
' The code breaks out once it reaches the timeout.
' 2) Provide a flag to tell the procedure to stop running.
' To use this option, you would need to pass the procedure a global flag
' that the user has the ability to change through the interface.
' Update (5/23/2008):
' - Uses a progressive sleep timer to allow fast processes to run quickly
' and long processes to get increasing clock cycles to work with.
' - Changed default window mode to hidden.

使用 CreateProcess 和 WaitForSingleObject API ：请参阅CreateProcess帮助页面上的“Super Shell”示例
调用Microsoft® Windows® Script Host会导致窗口显示消息。而是试试这个
Public Sub test()
Dim dos_command$, lRet&
dos_command = """\\xxx.xxx.xxx.xxx\xxx\xxx\7z.exe"" a test.zip ""\\xxx.xxx.xxx.xxx\xxx\xxx\*.log"" -r"
lRet = Shell(dos_command, vbMaximizedFocus)
