用VB控制EXCEL生成报表 做为一种简捷、系统的 Windows应用程序开发工具,Visual Basic 5 具有强大的数据处理功能,提供了多种数据访问方法,可以方便地存取Microsoft SQL Server、Oracle、XBase等多种数据库,被广泛应用于建立各种信息管理系统。但是,VB缺乏足够的、符合中文习惯的数据表格输出功能,虽然使用Crystal Report控件及 Crystal Reports程序可以输出报表,但操作起来很麻烦,中文处理能力也不理想。Excel作为Micorsoft公司的表格处理软件在表格方面有着强大的功能,我们可用VB5编写直接控制Excel操作的程序,方法是用VB的OLE自动化技术获取Excel 97 的控制句柄,从而直接控制Excel 97的一系列操作。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 8.0 Object Library;选择"确定"。在FORM的LOAD事件中加入: Data1.DatabaseName = 数据库名称 Data1.RecordSource = 表名 Data1.Refresh在按钮的CLICK事件中加入 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) .MoveFirst8 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本程序在中文Windows98、中文VB5下通过。 ------------------------------------------------------------------ 个人专栏:http://www.csdn.net/develop/author/netauthor/lihonggen0/ ------------------------------------------------------------------
