Question

我一直在努力寻找解决这个问题的方法。我有一些python脚本需要定期更新，并希望能够使用宏来完成此任务。现在我双击文件，它们通过Shell执行没有问题。

Sub RunPyScript()

Dim Ret_Val As Variant
Dim command As String

command = Chr(34) & "C:\Users\Jon Doe\python.exe" & Chr(34) & " " & Chr(34) & "C:\Users\Jon Doe\" & "\Roto.py" & Chr(34)
Ret_Val = Shell(command, vbNormalFocus)

End Sub

当我尝试运行上面的宏时，看起来它的运行方式与双击时相同，但Shell在执行脚本之前退出（我认为这是问题，而不是正面）。如果有人能帮助我，我真的很感激。

Dim objShell
Dim command as String       'use this declaration type for VBA (Access/Excel)
'Dim command                 'use this declaration type for VBS (Script), instead of the direct declaration like as "As String"

command = Chr(34) & "C:\Users\John Doe\python.exe" & Chr(34) & " " & Chr(34) & "C:\Users\John Doe\" & "\roto.py" & Chr(34)
Set objShell = CreateObject("WScript.Shell")

objShell.Run command, 1, True

'Settings for WindowStyle:
'     0 Hide the window (and activate another window.)
'     1 Activate and display the window. (restore size and position) Specify this flag when displaying a window for the first time.
'     2 Activate & minimize.
'     3 Activate & maximize.
'     4 Restore. The active window remains active.
'     5 Activate & Restore.
'     6 Minimize & activate the next top-level window in the Z order.
' *** 7 Minimize. The active window remains active.
'     8 Display the window in its current state. The active window remains active.
'     9 Restore & Activate. Specify this flag when restoring a minimized window.
'    10 Sets the show-state based on the state of the program that started the application.

顺便说一下，您可以简单地使用2x引号将引号插入到字符串变量中，就像我在之前的源代码中使用它们一样。例如StrVariable=""""给出结果"。那么命令行的字符串将是：

command = """%USERPROFILE%\python.exe"" ""%USERPROFILE%\roto.py"""

结果是：

"C:\Users\John Doe\python.exe" "C:\Users\John Doe\roto.py"
