打开多个Word文档

标签: excel vba excel-vba

对于初学者来说,我的VBA体验有限,而且我主要是修改我在网上发布的内容。我有一个Excel宏,从Word表中的表(或表)中获取数据。我的问题是我有一千个Word文档,所以我想帮助一个解决方案,复制用户选择的文件夹中所有Word文档的数据。

这是我目前的代码:

Sub ImportWordTables()

'Imports cells from Word document Tables in multiple documents

   Dim wdDoc         As Object
   Dim TableNo       As Integer  'number of tables in Word doc
   Dim iTable        As Integer  'table number index
   Dim iRow          As Long     'row index in Excel
   Dim iCol          As Integer  'column index in Excel
   Dim ix  As Long
   ix = ActiveSheet.UsedRange.Row - 1 + ActiveSheet.UsedRange.Rows.Count
LastRow = ix

   wdFileName = Application.GetOpenFilename("Word files (*.doc*),*.doc*", MultiSelect = True, _
         "Browse for files containing table to be imported")


   If wdFileName = False Then Exit Sub '(user cancelled import file browser)

   Set wdDoc = GetObject(wdFileName)   'open Word file

   With wdDoc
      TableNo = 1
      If TableNo = 0 Then
         MsgBox "This document contains no tables", _
               vbExclamation, "Import Word Table"

      End If

      For iTable = 1 To TableNo
         With .tables(iTable)
            'copy cell contents from Word table cells to Excel cells in column A and B
            Cells(ix + 1, "A") = WorksheetFunction.Clean(.Cell(1, 2))
            Cells(ix + 1, "B") = WorksheetFunction.Clean(.Cell(2, 2))
            Cells(ix + 1, "C") = WorksheetFunction.Clean(.Cell(3, 2))
            Cells(ix + 1, "D") = WorksheetFunction.Clean(.Cell(4, 2))
            Cells(ix + 1, "E") = WorksheetFunction.Clean(.Cell(5, 2))
            Cells(ix + 1, "F") = WorksheetFunction.Clean(.Cell(6, 2))
            Cells(ix + 1, "G") = WorksheetFunction.Clean(.Cell(6, 3))
            Cells(ix + 1, "H") = WorksheetFunction.Clean(.Cell(7, 2))
            Cells(ix + 1, "I") = WorksheetFunction.Clean(.Cell(8, 2))
            Cells(ix + 1, "J") = WorksheetFunction.Clean(.Cell(9, 2))
            Cells(ix + 1, "K") = WorksheetFunction.Clean(.Cell(10, 2))
Cells(ix + 1, "L") = WorksheetFunction.Clean(.Cell(13, 2))
         End With
         Next iTable
   End With


   Set wdDoc = Nothing
       End Sub

我知道我需要创建一个循环,但我无法改变在类似问题中找到的任何循环示例。

虽然我很可能不会考虑使用Excel从“数千”Word文档中的表中收集数据,但我确实发现这是一个有趣的练习,所以这里是一些代码,我把它们放在一起做(我认为)你是问。我在这里列出了一些你可能想要调查的东西,不可否认,它超出了你所要求的范围,但我试图评论代码,以便你能弄清楚我想要完成的事情。

另外。 。 。关于Office Automation的一个非常重要的注意事项由于Office应用程序基于COM规范(至少是早期版本,不确定新版本),因此在创建和销毁对象时必须非常小心。 COM强制执行一条规则,该规则说明如果有一个对象持有对另一个对象的引用,则该另一个对象不能被销毁。这对Office自动化具有严重影响,因为大多数对象在各种方向上都相互引用。例如在Excel中; Excel应用程序不仅保存对工作簿的引用,而且工作簿还包含对工作表的引用。工作表包含对工作簿的引用(通过它的父属性),依此类推。因此,如果您创建一个Excel实例,然后获取对工作簿的引用,然后获取该工作簿中的工作表的引用,您可以尝试整天销毁该工作簿对象,它将永远不会消失,因为工作表正在引用它。对于Excel应用程序对象也是如此。在Office中创建对象的引用时,最好按照与创建对象相反的顺序销毁对象。创建:Excel =>工作簿=>工作表。销毁:设置工作表= Nothing => Workbook.Close,Set Workbook = Nothing => Excel.Quit,设置Excel =无。

不按照这个一般规则导致无数机器崩溃,因为三个或四个Excel实例(它占用大量内存)在机器上保持打开状态,因为该进程已经运行了几次并且对象还没有被删除破坏。

好的。 。 。我现在要离开我的肥皂盒了。这是我创建的代码。享受!
