机房收费系统中,好多查询的窗体都包含同一个功能:将数据库中查询到的数据显示在MSHFlexGrid控件中,然后再把MSHFlexGrid控件中的数据导出到Excel表格中。
虽然之前做过学生信息管理系统,不过并没有涉及到这个功能,因此记录于此,于己,回顾反思,于大家,分享学习。
方法一:在根目录中事先建立空的Excel表格
1、在与VB工程同一根目录中建立将要导入数据的Excel表格;
2、在VB事件中写代码:
Private Sub cmdExport_Click() Dim i As Integer Dim j As Integer myFlexGrid.Redraw = False '关闭表格重画,加快运行速度 Set xlApp = CreateObject("Excel.Application") '创建EXCEL对象 '打开已经存在的EXCEL工件簿文件 Set xlBook = xlApp.Workbooks.Open(App.Path & "\学生上机记录.xls") xlApp.Visible = True '设置EXCEL对象可见 Set xlSheet = xlBook.Worksheets("Sheet1") '设置活动工作表 For i = 0 To myFlexGrid.Rows - 1 '行循环 For j = 0 To myFlexGrid.Cols - 1 '列循环 myFlexGrid.Row = i myFlexGrid.Col = j '保存到EXCEL xlBook.Worksheets("Sheet1").Cells(i + 1, j + 1) = myFlexGrid.Text Next j Next i myFlexGrid.Redraw = True End Sub
方法二:直接引用VB中自带的Microsoft Excel 14.0 Object Library
1、在VB设计器中,工程→引用,引用Microsoft Excel 14.0 Object Library;
2、编写代码:
Private Sub cmdExport_Click() Dim i As Integer Dim j As Integer Dim xlApp As Excel.Application Dim xlBook As Excel.Workbook Dim xlSheet As Excel.Worksheet Set xlApp = CreateObject("Excel.Application") '实例化对象xlApp xlApp.Visible = True Set xlBook = xlApp.Workbooks.Add Set xlSheet = xlBook.Worksheets(1) For i = 0 To myFlexGrid.Rows - 1 For j = 0 To myFlexGrid.Cols - 1 myFlexGrid.Row = i myFlexGrid.Col = j xlSheet.Cells(i + 1, j + 1) = Trim(myFlexGrid.Text) Next Next End Sub
第一种方法不用引用Microsoft Excel 14.0 Object Library,但必须得在根目录下建立相应的Excel表格,第二种方法不用建立表格,直接引用Microsoft Excel 14.0 Object Library可以直接实例化,比较方便。
