让 Excel VBA 等待 Power Query 数据刷新继续

Question

我的方案：我有一些通过 PowerQuery 提取的数据表，我希望它们自动刷新数据、保存并关闭。我每天凌晨 1 点都有一个任务调度程序运行。问题是 Excel VBA 在进入下一步（保存）之前不等待 PowerQuery 更新。

有很多关于此的博客，我没有找到任何答案 - 但它让我找到了对我有用的东西！我对代码并不感到自豪，但它是：

     Public Sub DataRefresh()

DisplayAlerts = False

For Each objConnection In ThisWorkbook.Connections
    'Get current background-refresh value
    bBackground = objConnection.OLEDBConnection.BackgroundQuery

    'Temporarily disable background-refresh
    objConnection.OLEDBConnection.BackgroundQuery = False

    'Refresh this connection
    objConnection.Refresh

    'Set background-refresh value back to original value
    objConnection.OLEDBConnection.BackgroundQuery = bBackground
Next

Workbooks("DA List.xlsm").Model.Refresh
DoEvents

For i = 1 To 100000
Worksheets("DA List").Range("G1") = i
Next i
DoEvents

ActiveWorkbook.Save
Application.Quit

End Sub

我认为这是可行的，因为我给了 excel 除了数据刷新之外的事情要做，而且 DoEvents 和我的下一步之间的额外行似乎让 VBA 终于弄清楚我是什么打算。

希望对您有所帮助！！

'Set background-refresh value back to original value
objConnection.OLEDBConnection.BackgroundQuery = bBackground
Next
