由于我之前找的文档让我以为在创建表里面走了很大的误区,所以当时我直接就在学生管理系统的文件夹里建了张表,运行时候直接打开这样表就行了。但是这里面还是存在着很大的误区。

后来我看了周坤的博客感觉他比我的代码优化了好多。我代码里面的好多问题都在他这里面得到解决。(ORZ!!!我做了一下午,忽然有种白做的感觉。)

“导出为excel”这个按钮大体就是点击按钮便创建一张表,然后把myflexgrid写到表格里面。

先看一下我的代码的问题:

 

Set xlApp = CreateObject("Excel.Application") '创建EXCEL应用类

 

xlApp.Visible = True '设置EXCEL可见

1.

Set xlBook = xlApp.Workbooks.Open(App.Path & "\新建 Microsoft Excel 工作表.xls") '打开EXCEL工作簿

 

Set xlSheet = xlBook.Worksheets(1) '打开EXCEL工作表

 

xlSheet.Activate '激活工作表

2.

xlSheet.Cells(1, 1) = myflexgrid.TextMatrix(0, 0)……'给单元格1行驶列赋值…………

 

xlBook.RunAutoMacros (xlAutoOpen) '运行EXCEL中的启动宏

  1. 之前我已经定义了,而我这行代码是打开已有的工作簿,但是,add这个方法就是创建一个新工作簿。新工作簿将成为当前表的活动工作簿。(我之前一直以为add是添加内容的意思)
  2. 这行代码我只能控制表的第一行第一列,如果显示几十行怎么办?通过看系统里面代码可以用循环来完成。

    下面看一下我今天看到的代码:

    Dim xlsAppAs Excel.Application '定义Excel程序

    DimxlsBook As Excel.Workbook '定义工作簿

    DimxlsSheet As Excel.Worksheet '定义工作表

     

    Dim i As Long

     

    Dim j As Long

    SetxlsApp = CreateObject("Excel.Application") '创建应用程序

    Set xlsBook = xlsApp.Workbooks.Add

    创建一个新工作簿。新工作簿将成为当前表的活动工作簿。

    SetxlsSheet = xlsBook.Worksheets(1) '设置应用表

    With xlsApp

    .Rows(1).Font.Bold = True

    如何在设置excel中的字体进行设置

    End With

    '把myflexgrid.Rows的内容写入到电子表格中

    For i = 0 To myflexgrid.Rows - 1

    很好的利用了循环语句

    For j = 0 To myflexgrid.Rows - 1

     

    xlsSheet.Cells(i + 1, j + 1) = "'" & myflexgrid.Rows.TextMatrix(i, j)

    ’通过我上面写的可以明显的总结出这个规律

    Next j

    Next i

    xlsApp.Visible = True '显示电子表格

    'xlsSheet.PrintOut preview:=True '进入打印预览页面

    ' xlsBook.SaveAs App.Path & "\Test.xls" '保存路径和文件名称

    要是点一下就出现一张表这样也太麻烦了,而且文件名字还是一样的。所以我觉得这段代码有点多余。

    SetxlsApp = Nothing '释放控制权

    这样做出来的效果比我做的好得多。

    拓展:(excel更多操作)

    1)显示当前窗口:

     

    ExcelID.Visible:=True;

    2)更改Excel标题栏:

    ExcelID.Caption:='

    应用程序调用MicrosoftExcel';

    3)添加新工作簿:

     

    ExcelID.WorkBooks.Add;

    4)打开已存在的工作簿:

     

    ExcelID.WorkBooks.Open('C:\Excel\Demo.xls');

    5)设置第2个工作表为活动工作表:

    ExcelID.WorkSheets[2].Activate;

    或ExcelID.WorkSheets['Sheet2'].Activate;

    6)给单元格赋值:

     

    ExcelID.Cells[1,4].Value:='第一行第四列';

    7)设置指定列的宽度(单位:字符个数),以第一列为5例:

     

    ExcelID.ActiveSheet.Columns[1].ColumnsWidth:=5;

    8)设置指定行的高度(单位:磅)(1磅=0.035厘米),以第二行为例:

     

    ExcelID.ActiveSheet.Rows[2].RowHeight:=1/0.035;//1厘米

    9)在第8行之前插入分页符:

     

    ExcelID.WorkSheets[1].Rows[8].PageBreak:=1;

    10)在第8列之前删除分页符:

     

    ExcelID.ActiveSheet.Columns[4].PageBreak:=0;

    11)指定边框线宽度:

     

    ExcelID.ActiveSheet.Range['B3:D4'].Borders[2].Weight:=3; 1-左 2-右 3-顶4-底 5-斜(\) 6-斜(/)

    12)清除第一行第四列单元格公式:

     

    ExcelID.ActiveSheet.Cells[1,4].ClearContents;

    13)设置第一行字体属性:

     

    ExcelID.ActiveSheet.Rows[1].Font.Name:='隶书';

     

    ExcelID.ActiveSheet.Rows[1].Font.Color =clBlue;

     

    ExcelID.ActiveSheet.Rows[1].Font.Bold :=True;

     

    ExcelID.ActiveSheet.Rows[1].Font.UnderLine:=True;
