你可以使用Windows自带的任务计划程序（Task Scheduler）来实现任务调度功能，并且可以通过在Visual Basic中调用Windows API来控制任务计划程序。
以下是使用Windows API调用任务计划程序的示例代码：
'导入Windows API Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" _ (ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, _ ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long
'在任务计划程序中创建任务 Public Sub CreateTask(ByVal TaskName As String, ByVal FilePath As String, ByVal StartTime As Date, ByVal Interval As Integer) Dim TaskID As String '在任务计划程序中创建任务 TaskID = ShellExecute(0, "Open", "schtasks.exe", "/Create /TN " & TaskName & " /TR """ & FilePath & """ /SC MINUTE /MO " & CStr(Interval) & " /ST " & Format(StartTime, "hh:mm:ss"), "", 0) End Sub
'查询任务计划程序中的任务状态 Public Function QueryTaskState(ByVal TaskName As String) As String Dim State As String '查询任务状态 State = ShellExecute(0, "Open", "schtasks.exe", "/Query /TN " & TaskName, "", 0) If State Like "运行中" Then QueryTaskState = "运行中" ElseIf State Like "准备中" Or State Like "计划中" Then QueryTaskState = "计划中" ElseIf State Like "未启动" Then QueryTaskState = "未启动" End If End Function
'删除任务计划程序中的任务 Public Sub DeleteTask(ByVal TaskName As String) '删除任务 ShellExecute 0, "Open", "schtasks.exe", "/Delete /TN " & TaskName & " /F", "", 0 End Sub
这是一个简单的示例代码，你可以根据自己的需要进行修改和扩展。希望能够帮助你解决问题。
