Question

我有一个工作簿，该工作簿有几千行，需要在其中确定每行的第一个和最后一个出现的“ Y”。（这些字符根据其所属的列与特定的日期相关联）。我必须找到这些字符的开始和停止时间，因为它将给我每个任务的开始和停止日期。到目前为止，我已经尝试过：

Public Sub import_gbs()
Dim wb As Workbook
Dim gbs_wb As Workbook
Dim gbs_bg As Worksheet
Dim gbs_drivers As Worksheet
Dim bg As Worksheet
Dim dict As Scripting.Dictionary
Dim date_array() As String
Dim x As Long
Dim i As Long
Dim switch As Integer
Dim start_position As Integer
Dim stop_position As Integer    

Application.ScreenUpdating = False
Application.DisplayAlerts = False
Application.EnableEvents = False
Application.Calculation = xlCalculationManual
Application.TransitionNavigKeys = False

Set wb = ThisWorkbook
Set bg = wb.Sheets("Current EDGE")
Application.AutomationSecurity = msoAutomationSecurityForceDisable
Set gbs_wb = Workbooks.Open("C:\SOME PATH HERE\")
Application.AutomationSecurity = msoAutomationSecurityByUI
Set gbs_bg = gbs_wb.Sheets("CC Input")
Set gbs_drivers = gbs_wb.Sheets("Drivers")
Set dict = New Scripting.Dictionary '''

dict.Add "SU YN Start", gbs_drivers.Cells(9, 5).Value
dict.Add "SU YN Stop", gbs_drivers.Cells(9, 6).Value
dict.Add "EPMP1 YN Start", gbs_drivers.Cells(10, 5).Value
dict.Add "EPMP1 YN Stop", gbs_drivers.Cells(10, 6).Value
dict.Add "EPMP2 YN Start", gbs_drivers.Cells(11, 5).Value
dict.Add "EPMP2 YN Stop", gbs_drivers.Cells(11, 6).Value
dict.Add "RC YN Start", gbs_drivers.Cells(12, 5).Value
dict.Add "RC YN Stop", gbs_drivers.Cells(12, 6).Value
dict.Add "ON YN Start", gbs_drivers.Cells(13, 5).Value
dict.Add "ON YN Stop", gbs_drivers.Cells(13, 6).Value
dict.Add "FU YN Start", gbs_drivers.Cells(14, 5).Value
dict.Add "FU YN Stop", gbs_drivers.Cells(14, 6).Value
dict.Add "DB Lock YN Start", gbs_drivers.Cells(15, 5).Value
dict.Add "DB Lock YN Stop", gbs_drivers.Cells(15, 6).Value
dict.Add "CO/Reporting YN Start", gbs_drivers.Cells(16, 5).Value
dict.Add "CO/Reporting YN Stop", gbs_drivers.Cells(16, 6).Value

i = 2
For x = 3 To 9543
    If gbs_bg.Cells(x, 25).Value > 0 Then
        start_position = gbs_bg.Range("AI" & x & ":" & "AP" & x).Find(what:="Y", lookat:=xlWhole, searchdirection:=xlNext).Column
        stop_position = gbs_bg.Range("AI" & x & ":" & "AP" & x).Find(what:="Y", lookat:=xlWhole, searchdirection:=xlPrevious).Column

        Select Case start_position
        Case 35
            gbs_bg.Cells(x, 65).Value = dict("SU YN Start")
        Case 36
            gbs_bg.Cells(x, 65).Value = dict("EPMP1 YN Start")
        Case 37
            gbs_bg.Cells(x, 65).Value = dict("EPMP2 YN Start")
        Case 38
            gbs_bg.Cells(x, 65).Value = dict("RC YN Start")
        Case 39
            gbs_bg.Cells(x, 65).Value = dict("ON YN Start")
        Case 40
            gbs_bg.Cells(x, 65).Value = dict("FU YN Start")
        Case 41
            gbs_bg.Cells(x, 65).Value = dict("DB Lock YN Start")
        Case 42
            gbs_bg.Cells(x, 65).Value = dict("CO/Reporting YN Start")
        End Select

        Select Case stop_position
        Case 35
            gbs_bg.Cells(x, 66).Value = dict("SU YN Stop")
        Case 36
            gbs_bg.Cells(x, 66).Value = dict("EPMP1 YN Stop")
        Case 37
            gbs_bg.Cells(x, 66).Value = dict("EPMP2 YN Stop")
        Case 38
            gbs_bg.Cells(x, 66).Value = dict("RC YN Stop")
        Case 39
            gbs_bg.Cells(x, 66).Value = dict("ON YN Stop")
        Case 40
            gbs_bg.Cells(x, 66).Value = dict("FU YN Stop")
        Case 41
            gbs_bg.Cells(x, 66).Value = dict("DB Lock YN Stop")
        Case 42
            gbs_bg.Cells(x, 66).Value = dict("CO/Reporting YN Stop")
        End Select

        i = i + 1
    End If
 Next x

因此，大多数情况下，这对我有用。在少数几行中确实有一些奇怪的实例，在第35列中存在一个“ Y”，但是查找未命中它并在该行中选取了下一个“ Y”实例。在7,000多个行中，这种情况仅发生了几次，并且始终在第35列中出现（但大多数情况下，如果在该行的该列中找到“ Y”，则通常会在该列中找到）。显然，这弄乱了我这些行的日期。我不知道那会是什么。我尝试通过检查缺少“ Y”的单元格的长度和值来尝试调试。但是，该结果将返回1，并且值为“ Y”。我试图在搜索值和公式之间进行切换，但这也不起作用。

因此，我需要找到一种新的方式来查找事件。我在想，因为我知道vba确实可以正确识别每个单元格的值的长度，所以我可以以此为基础。但是我不确定如何开始。任何帮助，将不胜感激。谢谢！

最简单的方法是创建一个小的for循环，以遍历8列数据（从AI到AP）并找到第一个和最后一个出现的“ Y”，并检查这是否非常耗时。但是，通过手动计算和屏幕更新，它应该不会太长。在下面，您可以找到准备测试的简单子程序。

Option Explicit

Sub test()
    Application.ScreenUpdating = False
    Application.Calculation = xlCalculationManual

    Dim t#: t = Timer
    Dim wbs As Worksheet
    Dim x As Long
    Dim col As Integer
    Dim startposition As Integer
    Dim endposition As Integer

    Set wbs = ActiveSheet


    With wbs
        For x = 1 To 7000
            startposition = 0
            For col = 35 To 42
                If .Range(.Cells(x, col), .Cells(x, col)).Value = "Y" And startposition = 0 Then
                    startposition = col
                ElseIf .Range(.Cells(x, col), .Cells(x, col)).Value = "Y" And startposition <> 0 Then
                    endposition = col
                End If
            Next col
        Next x
    End With

    Debug.Print Timer - t

    Application.ScreenUpdating = True
    Application.Calculation = xlCalculationAutomatic
End Sub

我在空白纸上的分数是0.57s。您可以分析该代码，甚至可以实现该循环。对于x循环，仅是对7000行的模拟。

如何找到连续出现的字符串的第一个和最后一个？
