用于创建计划任务的VBScript

Question

我正在尝试创建一个创建批处理文件的VBScript,然后创建一个计划任务来运行批处理文件.到目前为止,我尝试的所有内容都创建了批处理文件,但是没有创建计划任务,我没有收到任何错误.这是我到目前为止:

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"",并得到了相同的结果.但是当我在命令提示符下运行以下命令时:

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

任务成功创建.

我尝试这种方法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,以及一个用于创建计划任务的批处理文件.然后我结束了最后运行task.bat文件.这就是我对此的看法:

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,但最后才打开cmd,之后什么也没做.

我的猜测是问题在于wShell.Run部分,但我没有足够的经验知道问题所在.

我不知道从哪里去,所以任何建议都会很棒.

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

这来自显示如何创建任务的文档.

时间触发示例(脚本)

此脚本示例显示如何创建在特定时间运行记事本的任务.该任务包含一个基于时间的触发器,它指定激活任务的起始边界,一个运行记事本的可执行操作,以及一个停用该任务的结束边界.

以下过程描述如何安排任务在特定时间启动可执行文件.

安排记事本在特定时间开始

1. 创建一个TaskService对象.此对象允许您在指定的文件夹中创建任务.

2. 获取任务文件夹并创建任务.使用该TaskService.GetFolder方法获取存储任务的文件夹以及TaskService.NewTask创建表示任务的TaskDefinition对象的方法.

3. 使用TaskDefinition对象定义有关任务的信息.使用该TaskDefinition.Settings属性可以定义用于确定Task Scheduler服务如何执行任务的设置,以及TaskDefinition.RegistrationInfo用于定义描述任务的信息的属性.
4. 使用TaskDefinition.Triggers属性创建基于时间的触发器.此属性提供对TriggerCollection对象的访问.使用该TriggerCollection.Create方法(指定要创建的触发器类型)来创建基于时间的触发器.在创建触发器时,设置触发器的起始边界和结束边界以激活和取消激活触发器.起始边界指定何时执行任务的操作.
5. 使用该TaskDefinition.Actions属性为要执行的任务创建操作.此属性提供对ActionCollection对象的访问.使用此ActionCollection.Create方法指定要创建的操作类型.此示例使用一个ExecAction对象,该对象表示执行命令行操作的操作.
6. 使用该TaskFolder.RegisterTaskDefinition方法注册任务.对于此示例,任务将在当前时间加30秒启动记事本.

以下VBScript示例显示如何在注册任务30秒后安排任务执行记事本.

' This sample schedules a task to start notepad.exe 30 seconds
' from the time the task is registered.
'------------------------------------------------------------------

' A constant that specifies a time-based trigger.
const TriggerTypeTime = 1

Answer 2

不需要cmd。Schtasks是其自己的可执行文件，而不是中的命令cmd。对于引用的参数，只需使用两个引号即可。

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
