Excel / VBA在執行打開/關閉工作簿的循環期間凍結

Question

我的vba程序必須打開/關閉約150個工作簿。 它曾經做得很好，但是突然間在打開和關閉工作簿的循環執行過程中凍結。 它適用於較小的設備。

我嘗試解決的問題：

-在安全模式下運行Excel。

-減小了我最大模塊的尺寸

-修復的Excel。

我認為這只是超級慢，添加一個application.screenupdating = false並與enableevents = false相同

避免使用公共變量（磁盤，網絡）

可以使用Long而不是Integer（速度更快，超過65k不會令人驚訝）

如果工作簿每次都粘貼為函數的參數，為什么還要激活它呢？

打開許多工作簿時，您可能希望擁有更快的磁盤（SSD）

我知道您使用一個名為sheet的變量作為temp，為什么不在函數結束前設置sheet = nothing？
