下面给出一个实例: 首先建立一个窗体(FORM1)在窗体中加入一个DATA控件和一按钮, 引用Microsoft Excel类型库: 从"工程"菜单中选择"引用"栏; 选择Microsoft Excel 9.0 Object Library; 选择"确定"。 然后在FORM的LOAD事件中加入: Private Sub Form_Load() '数据库及表可以另选,本文以Nwind.mdb为例 Data1.DatabaseName = "C:\Program Files\Microsoft Visual Studio\VB98\Nwind.mdb" Data1.RecordSource = "Customers" Data1.Refresh End Sub 在按钮的CLICK事件中加入 Private Sub Command1_Click() Dim Irow, Icol As Integer Dim Irowcount, Icolcount As Integer Dim Fieldlen() '存字段长度值 Dim xlApp As Excel.Application Dim xlBook As Excel.Workbook Dim xlSheet As Excel.Worksheet Set xlApp = CreateObject("Excel.Application") Set xlBook = xlApp.Workbooks.Add Set xlSheet = xlBook.Worksheets(1) With Data1.Recordset .MoveLast If .RecordCount < 1 Then MsgBox ("Error 没有记录!") Exit Sub End If Irowcount = .RecordCount '记录总数 Icolcount = .Fields.Count '字段总数 ReDim Fieldlen(Icolcount) .MoveFirst For Irow = 1 To Irowcount + 1 For Icol = 1 To Icolcount Select Case Irow Case 1 '在Excel中的第一行加标题 xlSheet.Cells(Irow, Icol).Value = .Fields(Icol - 1).Name Case 2 '将数组FIELDLEN()存为第一条记录的字段长 If IsNull(.Fields(Icol - 1)) = True Then Fieldlen(Icol) = LenB(.Fields(Icol - 1).Name) '如果字段值为NULL,则将数组Filelen(Icol)的值设为标题名的宽度 Else Fieldlen(Icol) = LenB(.Fields(Icol - 1)) End If xlSheet.Columns(Icol).ColumnWidth = Fieldlen(Icol) 'Excel列宽等于字段长 xlSheet.Cells(Irow, Icol).Value = .Fields(Icol - 1) '向Excel的CellS中写入字段值 Case Else Fieldlen1 = LenB(.Fields(Icol - 1)) If Fieldlen(Icol) < Fieldlen1 Then xlSheet.Columns(Icol).ColumnWidth = Fieldlen1 '表格列宽等于较长字段长 Fieldlen(Icol) = Fieldlen1 '数组Fieldlen(Icol)中存放最大字段长度值 Else xlSheet.Columns(Icol).ColumnWidth = Fieldlen(Icol) End If xlSheet.Cells(Irow, Icol).Value = .Fields(Icol - 1) End Select Next If Irow <> 1 Then If Not .EOF Then .MoveNext End If Next With xlSheet .Range(.Cells(1, 1), .Cells(1, Icol - 1)).Font.Name = "黑体" '设标题为黑体字 .Range(.Cells(1, 1), .Cells(1, Icol - 1)).Font.Bold = True '标题字体加粗 .Range(.Cells(1, 1), .Cells(Irow, Icol - 1)).Borders.LineStyle = xlContinuous '设表格边框样式 End With xlApp.Visible = True '显示表格 xlBook.Save '保存 Set xlApp = Nothing '交还控制给Excel End With End Sub
你在进行完操作的时候,添加语句
xlApp.Quit
Set xlApp = Nothing其中xlApp是你声明的Excel.Application对象
execl文件,就出现这样的问题
用xlApp.Quit
无法在程序结束是退出EXCEL
