用VB控制EXCEL生成报表 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。
