Question

我正在尝试创建允许用户打开它并自动安装加载项的自动安装程序，但是在此期间我遇到了一些问题。

一个问题与文件扩展名有关，由于某种原因它允许.xla但不允许.xlam，如果我将其保留为.xla，则表示文件是每当尝试打开.xlam时打开工作簿的第二个问题，它就会损坏，它不允许我安装它，错误1004无法从Addins class获得添加属性。

任何帮助将不胜感激。

Answer 1

我认为问题是AddinTitle = Left(.Name, Len(.Name) - 4)，因为硬编码4必须在.xls和.xlsx扩展范围之间进行调整，否则您可能会留双倍的时间，即..

Answer 2

最终找到了我的问题的答案，所以它确实与save方法失败有关。

因此而不是下面的行：

(450-50)/(300+300)=0.666

对此进行了更改，并且很明显，我根据您的建议更改了代码的某些部分。

.SaveAs Application.UserLibraryPath & AddinName

Answer 3

在保存文件的同时，还需要提及FileFormat选项。

所以不是

.SaveAs Application.UserLibraryPath & AddinName

您可以将文件格式称为

.SaveAs Application.UserLibraryPath & AddinTitle FileFormat:=xlAddin

另一个问题

您不能Kill运行当前代码的文件。

基本上，代码中的所有Kill ...语句都会产生权限错误，因为正在运行的代码会在文件上加锁，而vba Kill不是同步函数。
