用于创建计划任务的 VBScript

Question

我正在尝试创建一个 VBScript，它创建一个批处理文件，然后为运行该批处理文件创建一个计划任务。到目前为止，我尝试过的所有操作都会创建批处理文件，但不会创建计划任务，而且我还没有收到任何错误。这是我目前所拥有的：

Option Explicit

Dim objFSO, outFile, wShell
Set objFSO = CreateObject("Scripting.FileSystemObject")

Set outFile = objFSO.CreateTextFile("C:\test.bat", True)
outFile.WriteLine "Start www.google.com"
outFile.Close

Set wShell = CreateObject ("Wscript.Shell") 
wShell.Run "cmd SchTasks /Create /SC WEEKLY /D MON,TUE,WED,THU,FRI /TN 'Test Task' /TR 'C:\test.bat' /ST 16:30", 0

我试过 ""Test Task"" 和 ""C:\test.bat""，得到了相同的结果。但是当我运行在命令提示符下执行以下命令时：

SchTasks /Create /SC WEEKLY /D MON,TUE,WED,THU,FRI /TN "Test Task" /TR "C:\test.bat" /ST 16:30

任务创建成功。

我尝试的另一种方法是创建 2 个批处理文件：一个用于打开网页的批处理文件，一个用于创建计划任务的批处理文件。然后我在最后运行宁 task.bat 文件结束。这是我为此准备的：

Option Explicit

Dim objFSO, outFile, wShell
Set objFSO = CreateObject("Scripting.FileSystemObject")

Set outFile = objFSO.CreateTextFile("C:\test.bat", True)
outFile.WriteLine "Start www.google.com"
outFile.Close

Set outFile = objFSO.CreateTextFile("C:\task.bat", True)
outFile.WriteLine "SchTasks /Create /SC WEEKLY /D MON,TUE,WED,THU,FRI /TN ""Test Task"" /TR ""C:\test.bat"" /ST 16:30"

Set wShell = CreateObject ("Wscript.Shell") 
wShell.Run "cmd start ""C:\task.bat"""

这创建了批处理文件，但最后只是打开了 cmd，此后什么也没做。

我的猜测是问题出在wShell.Run部分，但我经验不足，不知道问题出在哪里。

我不确定从这里到哪里去，所以任何建议都很好。

Answer 1

不需要cmd。 Schtasks 是它自己的可执行文件，而不是 cmd 中的命令。对于您引用的参数，只需使用两个引号。

例如：

wShell.Run "SchTasks /Create /SC WEEKLY /D MON,TUE,WED,THU,FRI /TN ""Test Task"" /TR ""C:\test.bat"" /ST 16:30", 0

Answer 2

在脚本中，您在命令中使用了单引号，而在您的 CMD 测试中，您使用了双引号。如果你运行 .. 它仍然有效吗？:

SchTasks /Create /SC WEEKLY /D MON,TUE,WED,THU,FRI /TN 'Test Task' /TR 'C:\test.bat' /ST 16:30

如果不是，请尝试使用双引号并将它们加倍转义：

wShell.Run "SchTasks /Create /SC WEEKLY /D MON,TUE,WED,THU,FRI /TN ""Test Task"" /TR ""C:\test.bat"" /ST 16:30", 0

Answer 3

作为 VBScript，您可以执行命令可以执行的任何操作。

以下是在根文件夹中列出计划任务的方法。

Set TS = CreateObject("Schedule.Service")
TS.Connect("Serenity")

Set rootFolder = TS.GetFolder("\")

Set tasks = rootFolder.GetTasks(0)

If tasks.Count = 0 Then 
    Wscript.Echo "No tasks are registered."
Else
    WScript.Echo "Number of tasks registered: " & tasks.Count

    For Each Task In Tasks
    A=Task.Name
    A = A & " " & Task.NextRunTime
    A = A & " " & Task.LastTaskResult
    wscript.echo A
    Next
End If

Time Trigger Example (Scripting)

This scripting example shows how to create a task that runs Notepad at a specific time. The task contains a time-based trigger that specifies a start boundary to activate the task, an executable action that runs Notepad, and an end boundary that deactivates the task.

The following procedure describes how to schedule a task to start an executable at a specific time.

To Schedule Notepad to start at a Specific Time

Create a TaskService object. This object allows you to create the task in a specified folder.

Get a task folder and create a task. Use the TaskService.GetFolder method to get the folder where the task is stored and the TaskService.NewTask method to create the TaskDefinition object that represents the task.

Define information about the task using the TaskDefinition object. Use the TaskDefinition.Settings property to define the settings that determine how the Task Scheduler service performs the task and the TaskDefinition.RegistrationInfo property to define the information that describes the task.

Create a time-based trigger using the TaskDefinition.Triggers property. This property provides access to the TriggerCollection object. Use the TriggerCollection.Create method (specifying the type of trigger you want to create) to create a time-based trigger. As you create the trigger, set the start boundary and end boundary of the trigger to activate and deactivate the trigger. The start boundary specifies when the task's action will be performed.

Create an action for the task to execute by using the TaskDefinition.Actions property. This property provides access to the ActionCollection object. Use the ActionCollection.Create method to specify the type of action you want to create. This example uses an ExecAction object, which represents an action that executes a command-line operation.

Register the task using the TaskFolder.RegisterTaskDefinition method. For this example the task will start Notepad at the current time plus 30 seconds.

The following VBScript example shows how to schedule a task to execute Notepad 30 seconds after the task is registered.
' This sample schedules a task to start notepad.exe 30 seconds
' from the time the task is registered.
