find一切不是
我们的一个客户给我发送了这个巨大的 excel文件，我的任务之一就是构build一个能清理less量数据的macros。 现在，我find了一个excellent example ，其中一个用户build议使用Excel查找方法来加快这个过程… BTW是完美的工作。
但是 ，在我的情况下，我想保持匹配的行，并删除其余的。 我如何在VBA中做到这一点？ 例如，他们在说什么
Set rFound = .Columns(1).Find(What:="Cat", After:=.Cells(1, 1), LookIn:=xlValues, LookAt:=...)
我怎样才能将“什么”的值设置为“不”？ 我尝试了几个不同的东西，如：
- 昏暗的猫作为string|| 猫=“猫”|| 设置notCat <>猫…..什么：= notCat
- DIM notCat <>“猫”…..什么：= notCat
- 什么：<> “猫”
- 什么：=“<>”＆猫 … { 我不知道他们为什么这样build议，它只是将string从'猫'改为'<>猫'…我认为是错误的 }
这可能是一个非常愚蠢的问题…但我只是无法find正确的答案，并感到非常沮丧:(任何帮助将不胜感激！
With ActiveSheet.Range(Range("A1"), Cells(Rows.Count, 1).End(xlUp)) .AutoFilter Field:=1, Criteria1:="<>cat" .Offset(1, 0).SpecialCells(xlCellTypeVisible).EntireRow.Delete .AutoFilter End With
根据我上面的评论，还有@TimWilliams的回答，我认为AutoFilter可能是这样做的方式。
我一直忘记Excel没有范围Difference方法（与Intersect相反，但这并不意味着你不能用一些UDF创造性的类似逻辑。
看看Chip Pearson出色的FindAll方法 。 通常，Excel的.Find方法只返回一个单元格区域（或Nothing ）。 这对于你的问题并不是特别有用，因为它需要你做一个笨重的迭代和FindNext直到你用尽了这个范围。
使用FindAll方法返回所有匹配单元格的范围。 然后，我们可以遍历列中的单元格，并testing它们是否与FindAll方法返回的范围相交。 如果它们不相交，那么就没有匹配，所以我们可以删除这一行。
