Question

我有一个正在处理的宏，并且假设如果单元格的值等于IN，则循环遍历并将单元格的值存储到数组中。由于某种原因，数组为空。我是VBA的新手，并且怀疑我可能无法正确检索单元格值。以下是我的代码，感谢您的任何帮助，谢谢。

请注意，正在运行宏的Excel工作表实际上在那些单元格中包含内容，并且其中一些具有值IN。

    Option Explicit

Dim newbook As Boolean 'Flag if new book was created correctly

'Get size of Worksheet
Function size() As Long
    size = Cells(Rows.Count, "A").End(xlUp).Row
End Function

    End With

'pull data
Sub pull(size)
    Dim code() As Variant
    ReDim code(size - 1)
    For i = 1 To size
    'Check code column fo IN and Doctype column for 810
        If Cells(i, 17).Value = "IN" Then
            code(i) = Cells(i, 17).Value 'store in array
        End If
    Next i
     Call push(code)
End Sub

'push data to new workbook
Sub push(ByRef code() As Variant)
    activeBook = "TempEDX.xlsm"
    Workbooks(activeBook).Activate 'set new workbook as active book
    Dim txt As String
    For i = 1 To UBound(code)
        txt = txt & code(i) & vbCrLf
        'Cells(i + 1, 1).Value = code(i)
    Next i
    MsgBox txt
End Sub

Answer 1

您应该完全限定对Cells属性的调用。否则Cells使用活动的工作簿和工作表。就您而言，您已经在扫描pull方法之前创建了工作簿。因此，您实质上是在看一个空的工作表。

在拉动之后创建新工作簿，或者创建一个新的工作表变量并将其设置在开头，例如：

dim currentWorksheet as Worksheet
set currentWorksheet = Activesheet

然后，您应该将currentWorksheet传递到pull函数和size函数中。

我会做这样的事情：

    Option Explicit

'Variable Definitions ***********************************************************
Dim WorkbookSize As Long 'Var to hold number of rows in worksheet, used primarily to control loops
Dim newbook As Boolean 'Flag if new book was created correctly
Dim wb As Workbook 'var to hold workbook object
Dim TempPath As String 'var to hold local temp path to store newly created workbook
Dim i As Integer 'var used as counter for loops
Dim activeBook As String 'var to hold new workbook name


'Main Driver
Sub Main()
    Dim currentWorksheet As Worksheet
    Set currentWorksheet = ActiveSheet

    WorkbookSize = size(currentWorksheet) 'Run function to get workbook size
    newbook = False
    Dim values()
    values = pull(currentWorksheet, WorkbookSize)               'Run sub to pull data
    push create(), values
End Sub

'Get size of Worksheet
Function size(sh As Worksheet) As Long
    size = sh.Cells(Rows.COUNT, "A").End(xlUp).row
End Function

'Create workbook
Function create() As Workbook
    Set wb = Workbooks.Add
    TempPath = Environ("temp") 'Get Users local temp folder
    With wb
        .SaveAs Filename:=TempPath & "EDX.xlsm" _
        , FileFormat:=xlOpenXMLWorkbookMacroEnabled, CreateBackup:=False
        .ChangeFileAccess Mode:=xlReadOnly, WritePassword:="admin"
    End With

    Set create = wb
End Function

'pull data
Function pull(pullFromSheet As Worksheet, size) As Variant
    Dim code() As Variant
    ReDim code(size - 1)
    For i = 1 To size
    'Check code column fo IN and Doctype column for 810
        If pullFromSheet.Cells(i, 17).Value = "IN" Then
            code(i-1) = pullFromSheet.Cells(i, 17).Value 'store in array
        End If
    Next i
    pull = code
End Function

'push data to new workbook
Sub push(toWorkbook As Workbook, ByRef code() As Variant)
    'activeBook = "TempEDX.xlsm"

    'Workbooks(activeBook).Activate 'set new workbook as active book
    Dim newSheet As Worksheet
    Set newSheet = toWorkbook.Sheets(1)
    Dim txt As String
    For i = 0 To UBound(code)
        txt = txt & code(i) & vbCrLf
        newSheet.Cells(i + 1, 1).Value = code(i)
    Next i
    MsgBox txt
    newSheet.Activate 'just to make your new sheet active for the user
End Sub

我将Push代码移到了pull代码之外，还创建了函数而不是subs，因此您可以很好地处理要创建的新对象。

Answer 2

我认为您没有选择正确的工作表。

放一个

Sheets("NAME_OF_SHEET").Select

之前，例如

Sub push(ByRef code() As Variant)
  activeBook = "TempEDX.xlsm"
  Workbooks(activeBook).Activate 'set new workbook as active book
  Dim txt As String

  Sheets("NAME_OF_SHEET").Select
  For i = 1 To UBound(code)
      txt = txt & code(i) & vbCrLf
      'Cells(i + 1, 1).Value = code(i)
  Next i
  MsgBox txt
End Sub

谢谢

循环并将单元格值放入其中后，VBA数组为空
