EXCEL VBA编程的一些小结
首先创建 Excel 对象,使用ComObj:
Dim ExcelID as Excel.Application
Set ExcelID as new Excel.Application
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 Microsoft Excel';
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;
14) 进行页面设置:
a.页眉:
ExcelID.ActiveSheet.PageSetup.CenterHeader := '报表演示';
b.页脚:
ExcelID.ActiveSheet.PageSetup.CenterFooter := '第&P页';
c.页眉到顶端边距2cm:
ExcelID.ActiveSheet.PageSetup.HeaderMargin := 2/0.035;
d.页脚到底端边距3cm:
ExcelID.ActiveSheet.PageSetup.HeaderMargin := 3/0.035;
e.顶边距2cm:
ExcelID.ActiveSheet.PageSetup.TopMargin := 2/0.035;
f.底边距2cm:
ExcelID.ActiveSheet.PageSetup.BottomMargin := 2/0.035;
g.左边距2cm:
ExcelID.ActiveSheet.PageSetup.LeftMargin := 2/0.035;
h.右边距2cm:
ExcelID.ActiveSheet.PageSetup.RightMargin := 2/0.035;
i.页面水平居中:
ExcelID.ActiveSheet.PageSetup.CenterHorizontally := 2/0.035;
j.页面垂直居中:
ExcelID.ActiveSheet.PageSetup.CenterVertically := 2/0.035;
k.打印单元格网线:
ExcelID.ActiveSheet.PageSetup.PrintGridLines := True;
15) 拷贝操作:
a.拷贝整个工作表:
ExcelID.ActiveSheet.Used.Range.Copy;
b.拷贝指定区域:
ExcelID.ActiveSheet.Range[ 'A1:E2' ].Copy;
c.从A1位置开始粘贴:
ExcelID.ActiveSheet.Range.[ 'A1' ].PasteSpecial;
d.从文件尾部开始粘贴:
ExcelID.ActiveSheet.Range.PasteSpecial;
16) 插入一行或一列:
a. ExcelID.ActiveSheet.Rows[2].Insert;
b. ExcelID.ActiveSheet.Columns[1].Insert;
17) 删除一行或一列:
a. ExcelID.ActiveSheet.Rows[2].Delete;
b. ExcelID.ActiveSheet.Columns[1].Delete;
18) 打印预览工作表:
ExcelID.ActiveSheet.PrintPreview;
19) 打印输出工作表:
ExcelID.ActiveSheet.PrintOut;
20) 工作表保存:
If not ExcelID.ActiveWorkBook.Saved then
ExcelID.ActiveSheet.PrintPreview
End if
21) 工作表另存为:
ExcelID.SaveAs( 'C:\Excel\Demo1.xls' );
22) 放弃存盘:
ExcelID.ActiveWorkBook.Saved := True;
23) 关闭工作簿:
ExcelID.WorkBooks.Close;
24) 退出 Excel:
ExcelID.Quit;
25) 设置工作表密码:
ExcelID.ActiveSheet.Protect "123", DrawingObjects:=True, Contents:=True, Scenarios:=True
26) EXCEL的显示方式为最大化
ExcelID.Application.WindowState = xlMaximized
27) 工作薄显示方式为最大化
ExcelID.ActiveWindow.WindowState = xlMaximized
28) 设置打开默认工作薄数量
ExcelID.SheetsInNewWorkbook = 3
29) '关闭时是否提示保存(true 保存;false 不保存)
ExcelID.DisplayAlerts = False
30) 设置拆分窗口,及固定行位置
ExcelID.ActiveWindow.SplitRow = 1
ExcelID.ActiveWindow.FreezePanes = True
31) 设置打印时固定打印内容
ExcelID.ActiveSheet.PageSetup.PrintTitleRows = "$1:$1"
32) 设置打印标题
ExcelID.ActiveSheet.PageSetup.PrintTitleColumns = ""
33) 设置显示方式(分页方式显示)
ExcelID.ActiveWindow.View = xlPageBreakPreview
34) 设置显示比例
ExcelID.ActiveWindow.Zoom = 100
35) 让Excel 响应 DDE 请求
Ex.Application.IgnoreRemoteRequests = False
用VB操作EXCEL
Private Sub Command3_Click()
On Error GoTo err1
Dim i As Long
Dim j As Long
Dim objExl As Excel.Application '声明对象变量
Me.MousePointer = 11 '改变鼠标样式

Exit Sub
err1:

End Sub一般在搞透视表时,是先用录制宏的方法来实现的,当然可以再看下代码
