Question

我有一个宏通过目录进行计算并编译结果。我也参与其中跳过腐败或不可读的＆＃39; Excel文件，工作正常。

现在的问题是，它大部分时间都有效，但某些文件会给我一个溢出错误。我的代码有问题吗？还是工作簿？

我的代码的这一部分突出显示：

 lrw = ws.Columns("A:Y").Find("*", , xlValues, , xlRows, xlPrevious).Row

这是我的完整代码：

'added function to skip corrupt files and add the skipped to worksheet( works)

Answer 1

VBA Integer保持2字节，范围是-32,768到32,767。 VBA long是完整整数，持有4字节，范围是-2,147,483,648到2,147,486,647
