Set wb2 = Workbooks.Open("C:\\Users\\HP\\Desktop\\已处理新增.xlsm")报错为对象未定义

如果在 VBA 中出现“对象未定义”的错误，通常是因为代码中使用了未声明或未赋值的变量。在这段代码中，如果变量 `wb2` 在此之前没有声明或赋值，就会出现该错误。

为了解决这个问题，你可以在使用变量 `wb2` 之前声明它，并且在使用 `Workbooks.Open` 方法之前确保 Excel 应用程序处于活动状态。你可以将代码修改为以下内容：

Dim wb2 As Workbook
Set wb2 = Workbooks.Open("C:\Users\HP\Desktop\已处理新增.xlsm")

在这段修改后的代码中，变量 `wb2` 在使用之前被声明，并且使用了完整的文件路径，而不是使用两个反斜杠来表示一个。此外，你需要确保在使用 `Workbooks.Open` 方法之前使用 `Application.Activate` 方法将 Excel 应用程序激活。

相关问题

Set wb2 = Workbooks.Open("C:\\Users\\HP\\Desktop\\已处理新增.xlsm")

这段代码是 VBA 语言中用于打开一个名为“已处理新增.xlsm”的 Excel 工作簿的命令。具体解释如下：

- `Set wb2 = `：将打开的工作簿赋值给变量 wb2，以便后续代码可以引用该工作簿。
- `Workbooks.Open(`：打开一个 Excel 工作簿。
- `"C:\\Users\\HP\\Desktop\\已处理新增.xlsm"`：指定要打开的工作簿的路径和文件名。需要注意的是，在字符串中使用反斜杠 `\` 时需要使用两个反斜杠 `\\` 来表示一个。
- `)`：表示方法调用结束。

因此，这段代码的作用是将名为“已处理新增.xlsm”的 Excel 工作簿打开，并将其赋值给变量 wb2。

请帮我优化以下代码，使他在对比时如果只有原数据一行的情况就按代码的逻辑复制这一行并粘贴Sub CopySameDay() Dim ws As Worksheet Dim lastRow As Long Dim i As Long Dim copyRange As Range Dim pasteRange As Range Dim wb As Workbook Dim folderPath As String Dim fileName As String Dim asteRange As Range Set ws = ActiveSheet lastRow = ws.Cells(Rows.Count, "D").End(xlUp).Row For i = 2 To lastRow If Format(ws.Range("D" & i).Value, "yyyy-mm-dd") = Format(ws.Range("D" & i - 1).Value, "yyyy-mm-dd") And ws.Range("B" & i).Value = ws.Range("B" & i - 1).Value Then If copyRange Is Nothing Then Set copyRange = ws.Range("A" & i - 1) End If Set pasteRange = ws.Range("A" & i) Else If Not copyRange Is Nothing Then folderPath = Left(ThisWorkbook.FullName, InStrRev(ThisWorkbook.FullName, "\")) Set asteRange = ws.Range("B" & i - 1) fileName = asteRange.Value & ".xlsx" If Dir(folderPath & fileName) = "" Then Set wb = Workbooks.Add wb.SaveAs folderPath & fileName Else Set wb = Workbooks.Open(folderPath & fileName) End If wb.Sheets.Add(After:=wb.Sheets(wb.Sheets.Count)).Name = Format(copyRange.Offset(0, 3).Value, "yyyy-mm-dd") copyRange.Resize(i - copyRange.Row, ws.Columns.Count).Copy wb.Sheets(wb.Sheets.Count).Range("A1").PasteSpecial xlPasteValues wb.Save wb.Close Set copyRange = Nothing End If End If Next i If Not copyRange Is Nothing Then folderPath = Left(ThisWorkbook.FullName, InStrRev(ThisWorkbook.FullName, "\")) Set asteRange = ws.Range("B" & i - 1) fileName = asteRange.Value & ".xlsx" If Dir(folderPath & fileName) = "" Then Set wb = Workbooks.Add wb.SaveAs folderPath & fileName Else Set wb = Workbooks.Open(folderPath & fileName) End If wb.Sheets.Add(After:=wb.Sheets(wb.Sheets.Count)).Name = Format(copyRange.Offset(0, 3).Value, "yyyy-mm-dd") copyRange.Resize(lastRow - copyRange.Row + 1, ws.Columns.Count).Copy wb.Sheets(wb.Sheets.Count).Range("A1").PasteSpecial xlPasteValues wb.Save wb.Close End If End Sub

优化后的代码只在最后一行数据为唯一数据时进行额外的复制操作。在原代码中，在最后一行数据为唯一数据时，会进行两次复制操作。
