使用任务计划程序运行Access宏，但希望在运行时隐藏Access。看不到Access打开和关闭

要在任务计划程序中运行Access宏而不显示Access窗口，可以通过创建一个VBA脚本并使用Windows API函数来实现。以下是详细步骤和示例代码：

基础概念

任务计划程序是Windows操作系统中的一个组件，允许用户安排任务在特定时间或事件触发时自动执行。Access宏是一种自动化工具，用于执行一系列预定义的操作。通过结合这两者，可以实现自动化任务处理。

类型

简单任务：一次性执行的操作。
复杂任务：包含多个步骤和条件判断的任务。

应用场景

数据处理：定期导入、导出和分析数据。
报告生成：定时生成和发送报告。
系统维护：执行数据库备份和清理操作。

示例代码

以下是一个VBA脚本示例，用于在后台运行Access宏而不显示Access窗口：

Private Declare PtrSafe Function CreateProcess Lib "kernel32" Alias "CreateProcessA" ( _
    ByVal lpApplicationName As String, _
    ByVal lpCommandLine As String, _
    ByVal lpProcessAttributes As LongPtr, _
    ByVal lpThreadAttributes As LongPtr, _
    ByVal bInheritHandles As Long, _
    ByVal dwCreationFlags As Long, _
    ByVal lpEnvironment As LongPtr, _
    ByVal lpCurrentDirectory As String, _
    ByRef lpStartupInfo As STARTUPINFO, _
    ByRef lpProcessInformation As PROCESS_INFORMATION) As Long

Private Declare PtrSafe Function CloseHandle Lib "kernel32" ( _
    ByVal hObject As LongPtr) As Long

Private Type STARTUPINFO
    cb As Long
    lpReserved As String
    lpDesktop As String
    lpTitle As String
    dwX As Long
    dwY As Long
    dwXSize As Long
    dwYSize As Long
    dwXCountChars As Long
    dwYCountChars As Long
    dwFillAttribute As Long
    dwFlags As Long
    wShowWindow As Integer
    cbReserved2 As Integer
    lpReserved2 As LongPtr
End Type

Private Type PROCESS_INFORMATION
    hProcess As LongPtr
    hThread As LongPtr
    dwProcessId As Long
    dwThreadId As Long
End Type

Const SW_HIDE = 0
Const CREATE_NO_WINDOW = &H8000000

Sub RunAccessMacroHidden()
    Dim strPathToAccess As String
    Dim strPathToDatabase As String
    Dim strMacroName As String
    Dim strCommandLine As String
    Dim si As STARTUPINFO
    Dim pi As PROCESS_INFORMATION
    Dim lngResult As Long

    ' 设置Access可执行文件路径、数据库路径和宏名称
    strPathToAccess = "C:\Path\To\MSACCESS.EXE"
    strPathToDatabase = "C:\Path\To\YourDatabase.accdb"
    strMacroName = "YourMacroName"

    ' 构建命令行字符串
    strCommandLine = strPathToAccess & " " & strPathToDatabase & " /x " & strMacroName

    ' 初始化STARTUPINFO结构
    With si
        .cb = Len(si)
        .wShowWindow = SW_HIDE
    End With

    ' 创建进程
    lngResult = CreateProcess( _
        ByVal 0&, _
        ByVal strCommandLine, _
        ByVal 0&, _
        ByVal 0&, _
        False, _
        CREATE_NO_WINDOW, _
        ByVal 0&, _
        ByVal 0&, _
        si, _
        pi)

    ' 关闭句柄
    If lngResult <> 0 Then
        CloseHandle pi.hThread
        CloseHandle pi.hProcess
    End If
End Sub
