在VB中如何提取EXCEL表中的數據?
VB操作EXCEL
全面控制 Excel
首先創建 Excel 對象,使用ComObj:
Dim ExcelID as Excel.Application
Set ExcelID as new Excel.Application
1) 顯示當前窗口:
ExcelID.Visible := True;
2) 更改 Excel 標題欄:
ExcelID.Caption := \'應用程序調用 Microsoft Excel\';
3) 添加新工作簿:
ExcelID.WorkBooks.Add;
4) 打開已存在的工作簿:
ExcelID.WorkBooks.Open( \'C:\\Excel\\Demo.xls\' );
5) 設置第2個工作表為活動工作表:
ExcelID.WorkSheets[2].Activate;
或 ExcelID.WorkSheets[ \'Sheet2\' ].Activate;
6) 給單元格賦值:
ExcelID.Cells[1,4].Value := \'第一行第四列\';
7) 設置指定列的寬度(單位:字符個數),以第一列為例:
ExcelID.ActiveSheet.Columns[1].ColumnsWidth := 5;
8) 設置指定行的高度(單位:磅)(1磅=0.035厘米),以第二行為例:
ExcelID.ActiveSheet.Rows[2].RowHeight := 1/0.035; // 1厘米
9) 在第8行之前插入分頁符:
ExcelID.WorkSheets[1].Rows[8].PageBreak := 1;
參考代碼:ActiveSheet.HPageBreaks(1).Location = Range("A22")
10) 在第8列之前刪除分頁符:
ExcelID.ActiveSheet.Columns[4].PageBreak := 0;
11) 指定邊框線寬度:
ExcelID.ActiveSheet.Range[ \'B3:D4\' ].Borders[2].Weight := 3;
1-左 2-右 3-頂 4-底 5-斜( \\ ) 6-斜( / )
12) 清除第一行第四列單元格公式:
ExcelID.ActiveSheet.Cells[1,4].ClearContents;
13) 設置第一行字體屬性:
ExcelID.ActiveSheet.Rows[1].Font.Name := \'隸書\';
ExcelID.ActiveSheet.Rows[1].Font.Color := clBlue;
ExcelID.ActiveSheet.Rows[1].Font.Bold := True;
ExcelID.ActiveSheet.Rows[1].Font.UnderLine := True;
14) 進行頁面設置:
a.頁眉:
ExcelID.ActiveSheet.PageSetup.CenterHeader := \'報表演示\';
b.頁腳:
ExcelID.ActiveSheet.PageSetup.CenterFooter := \'第&P頁\';
c.頁眉到頂端邊距2cm:
ExcelID.ActiveSheet.PageSetup.HeaderMargin := 2/0.035;
d.頁腳到底端邊距3cm:
ExcelID.ActiveSheet.PageSetup.HeaderMargin := 3/0.035;
e.頂邊距2cm:
ExcelID.ActiveSheet.PageSetup.TopMargin := 2/0.035;
f.底邊距2cm:
ExcelID.ActiveSheet.PageSetup.BottomMargin := 2/0.035;
g.左邊距2cm:
ExcelID.ActiveSheet.PageSetup.LeftMargin := 2/0.035;
h.右邊距2cm:
ExcelID.ActiveSheet.PageSetup.RightMargin := 2/0.035;
i.頁面水平居中:
ExcelID.ActiveSheet.PageSetup.CenterHorizontally := 2/0.035;
j.頁面垂直居中:
ExcelID.ActiveSheet.PageSetup.CenterVertically := 2/0.035;
k.打印單元格網線:
ExcelID.ActiveSheet.PageSetup.PrintGridLines := True;
15) 拷貝操作:
a.拷貝整個工作表:
ExcelID.ActiveSheet.Used.Range.Copy;
b.拷貝指定區域:
ExcelID.ActiveSheet.Range[ \'A1:E2\' ].Copy;
c.從A1位置開始粘貼:
ExcelID.ActiveSheet.Range.[ \'A1\' ].PasteSpecial;
d.從文件尾部開始粘貼:
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) 刪除一行或一列:
a. ExcelID.ActiveSheet.Rows[2].Delete;
b. ExcelID.ActiveSheet.Columns[1].Delete;
18) 打印預覽工作表:
ExcelID.ActiveSheet.PrintPreview;
19) 打印輸出工作表:
ExcelID.ActiveSheet.PrintOut;
20) 工作表保存:
If not ExcelID.ActiveWorkBook.Saved then
ExcelID.ActiveSheet.PrintPreview
End if
21) 工作表另存為:
ExcelID.SaveAs( \'C:\\Excel\\Demo1.xls\' );
22) 放棄存盤:
ExcelID.ActiveWorkBook.Saved := True;
23) 關閉工作簿:
ExcelID.WorkBooks.Close;
24) 退出 Excel:
ExcelID.Quit;
25) 設置工作表密碼:
ExcelID.ActiveSheet.Protect "123", DrawingObjects:=True, Contents:=True, Scenarios:=True
26) EXCEL的顯示方式為最大化
ExcelID.Application.WindowState = xlMaximized
27) 工作薄顯示方式為最大化
ExcelID.ActiveWindow.WindowState = xlMaximized
28) 設置打開默認工作薄數量
ExcelID.SheetsInNewWorkbook = 3
29) \'關閉時是否提示保存(true 保存;false 不保存)
ExcelID.DisplayAlerts = False
30) 設置拆分窗口,及固定行位置
ExcelID.ActiveWindow.SplitRow = 1
ExcelID.ActiveWindow.FreezePanes = True
31) 設置打印時固定打印內容
ExcelID.ActiveSheet.PageSetup.PrintTitleRows = "$1:$1"
32) 設置打印標題
ExcelID.ActiveSheet.PageSetup.PrintTitleColumns = ""
33) 設置顯示方式(分頁方式顯示)
ExcelID.ActiveWindow.View = xlPageBreakPreview
34) 設置顯示比例
ExcelID.ActiveWindow.Zoom = 100
35) 讓Excel 響應 DDE 請求
Ex.Application.IgnoreRemoteRequests = False
