用于大型数据集的堆栈空间VBA
我正在尝试为列中每个具有相同值的行集合创build一个新工作表。 我的列'line_name'具有像第1行，第2行，第3行，第12行的条目
我想为line_name = Line 1的所有行创build一个新工作表，为line_name = Line 2 …的所有行创build一个新工作表
我不断收到堆栈空间错误。 我的代码有问题还是我的表（40K行）太大？

我相信你的代码是recursion的：
Sub Copy_To_Worksheets() ... Set My_Range = Range("A1:S" & LastRow(ActiveSheet)) ... End Sub Function LastRow(sh As Worksheet) ... Application.Run "file_name.xlsx!Copy_To_Worksheets" ... End Function
所以它会很快耗尽内存。
对于“LastRow”函数来说，调用macros来调用数据到另一个工作表是非常奇怪的，所以我不认为你真的打算拥有这个“Application.Run”（实际上有两个）在那个function。
猜猜你试图将代码分成两部分，感到困惑。
这是你的LastRow（）应该做的：
Function LastRow(sh As Worksheet) Dim oRng as Range Set oRng = sh.Cells.Find(What:="*", _ After:=sh.Range("A1"), _ Lookat:=xlPart, _ LookIn:=xlValues, _ SearchOrder:=xlByRows, _ SearchDirection:=xlPrevious, _ MatchCase:=False) If oRng Is Nothing Then Debug.Print "NO BOTTOM FREE CELL FOUND!" LastRow = 0 Else LastRow = oRng.Row End If End Function
