Question

如果已创建一个VBS脚本，该脚本会监视新创建的进程，如notepad.exe或calc.exe。当发现新的记事本或计算过程时，我喜欢使用找到的进程名在powershell中执行某些操作。

当我手动编辑VBS文件中的进程名时，我创建的VBS脚本工作正常，但是当我尝试使用/传递进程名形式vbs（strName）到powershell时，我希望看到进程名（notepad.exe），但是，PowerShell窗口显示＆＃34; strName＆＃34;。

我已经在互联网上找到了一个没有结果的解决方案。

任何想法？

Answer 1

变化：

WshShell.Run("Powershell.exe -file .\GetParamFromVBS.ps1 ""strName"" ")

要：

WshShell.Run("Powershell.exe -file .\GetParamFromVBS.ps1 '" & strName & "'")

Answer 2

变量不是字符串文字。

这样的事情

a = "a string literal" & aVariableContainingAString
