Excel VBA从单元格中更改

为了解释我的标题，基本上我有一个宏代码，它将以秒的形式显示，请求从我们的共享邮箱导出它的天数。现在每天我都要改变我们需要出口的天数，这真的让人沮丧。下面这一行有问题：

If VBA.DateValue(VBA.Now) - VBA.DateValue(vItem.ReceivedTime) <= 10 Then

---

如果VBA.DateValue（VBA.Now）-VBA.DateValue（vItem.ReceivedTime）只是为了与excel和宏保持一致，工作簿是一个完整的xlsm文件，其中包含一组工作表（您将数据放在其中的各个选项卡）。通过一个单独的电子表格，我假设一个不同的工作簿

是一些从电子表格中获取数据的有用代码

主函数GetData位于底部，而不是将数据存储在本地单元格中，您只需将其放在变量中，并在“抱歉，它设置为同一工作簿但不同的工作表，以及您认为如何将其作为变量分发为最佳方式”中使用它。
