我知道有很多与此主题相关的线程，例如不要使用“选择”或“激活”，或者如果需要使用它，请将其设置为 false。我每次使用“select”或“activate”时都将其设置为False，但仍然不起作用，请帮忙！！

我也有类似的问题。使用
Application.ScreenUpdating = False使用消息框和
Debug.PrintDim rowCounter As Integer
For rowCounter = 1 To numberOfEmployees
'Do some work
If (someCondition) Then
startCell.offset(rowCounter).Value = ""
Else
startCell.offset(rowCounter).Value = "something else"
End If
Next rowCounter
如果我替换了以下行
startCell.offset(rowCounter).Value = ""
与任一
startCell.offset(rowCounter).Value = "anything except empty"
或
startCell.offset(rowCounter).ClearContents
然后闪烁停止，执行循环的时间从几秒缩短到远小于 1 秒。
我不知道为什么这会起作用。
因此，如果循环中的任何单元格返回空字符串，您可以尝试使用这两行之一。
不要将禁用和启用放在同一个程序/模块/功能中。 根据需要保留 Application.ScreenUpdating = False 并将 Application.ScreenUpdating = true 放置在此过程/模块/函数之外。对我来说，这是唯一真正有效的方法。
我也有同样的问题。 感谢这次讨论，我通过在 Application.Run "ATPVBAEN.XLAM!Regress" 等语句之前和之后放置 Application.ScreenUpdating = False 解决了问题：
Application.ScreenUpdating = False
Application.Run "ATPVBAEN.XLAM!Regress", sht.Range("$B$1", "$B" & LastRecordRow), _
sht.Range("$C$1", "$C" & LastRecordRow), False, True, , sht.Range("$I$1") _
, False, False, False, False, , False
Application.ScreenUpdating = False
必须是那个程序，在我使用那个程序之前我的应用程序运行良好。
我发现，如果代码中较早的某个位置存在应用程序级命令，例如将计算从自动更改为手动，或者如果您正在处理多个文件，则 ScreenUpdating=False 不会启动同时。这个想法是，如果您可以尽早将 ScreenUpdating=False 放在任何其他应用程序级命令之前，那么它就越有可能起作用。
