vb.net將excel一個區(qū)域的內(nèi)容復(fù)制到另外一個區(qū)域

對 Range 對象做 Copy 方法，要注意 Range 要連續(xù)的、成矩形選擇的。

例如像：A1:C5 可以復(fù)制，

例如像：A1:C5, A10:C15 就不能復(fù)制。

還要注意一點(diǎn)：對 Range 對象進(jìn)行操作的話，所在工作表先要激活。

someRange.Worksheet.Activate

如果還有問題的話，可以把對 Excel 操作的代碼提取到 Excel VBA 環(huán)境下調(diào)試好了再移植回去。

vb.net中怎么將chart中的圖表復(fù)制到剪貼板和另存為成圖片文件？求大神幫助

private void Save_Click(object sender, System.EventArgs e) { // Create a new save file dialog SaveFileDialog saveFileDialog1 = new SaveFileDialog(); // Sets the current file name filter string, which determines // the choices that appear in the "Save as file type" or // "Files of type" box in the dialog box. saveFileDialog1.Filter = "Bitmap (*.bmp)|*.bmp|JPEG (*.jpg)|*.jpg|EMF (*.emf)|*.emf|PNG (*.png)|*.png|SVG (*.svg)|*.svg|GIF (*.gif)|*.gif|TIFF (*.tif)|*.tif"; saveFileDialog1.FilterIndex = 2 ; saveFileDialog1.RestoreDirectory = true ; // Set image file format if(saveFileDialog1.ShowDialog() == DialogResult.OK) { ChartImageFormat format = ChartImageFormat.Bmp; if( saveFileDialog1.FileName.EndsWith( "bmp" ) ) { format = ChartImageFormat.Bmp; } else if( saveFileDialog1.FileName.EndsWith( "jpg" ) ) { format = ChartImageFormat.Jpeg; } else if( saveFileDialog1.FileName.EndsWith( "emf" ) ) { format = ChartImageFormat.Emf; } else if( saveFileDialog1.FileName.EndsWith( "gif" ) ) { format = ChartImageFormat.Gif; } else if( saveFileDialog1.FileName.EndsWith( "png" ) ) { format = ChartImageFormat.Png; } else if( saveFileDialog1.FileName.EndsWith( "tif" ) ) { format = ChartImageFormat.Tiff; } else if( saveFileDialog1.FileName.EndsWith( "svg" ) ) { format = ChartImageFormat.Svg; } // Save image Chart1.SaveImage( saveFileDialog1.FileName, format ); } }

復(fù)制某表的部分字段到新表 vb vb.net

說實(shí)話你這個題目不是很明確

讓我有點(diǎn)不明白你想要的代碼是什么

那么我的理解就是

你現(xiàn)在有兩個表,表1,表2

你選中表1的某行,然后把選中的這行添加到表2去

如果是這樣的話那么做法就是

運(yùn)行環(huán)境 VB2008(.NET)

假設(shè)窗體名稱為Form1,你添加六個控件出來

表格控件DataGridView1,DataGridView2

按扭控件四個Button1,Button2,Button3,Button4

然后清空窗體里所有代碼使用我的代碼就行了

Public Class Form1

Public LeafFileName As String = CurDir() "\Access.mdb" '這里是數(shù)據(jù)庫文件路徑和名稱,你自己改

Public LeafPassWord As String = "leafsoftpassword" '這里是數(shù)據(jù)庫密碼,如果沒有密碼就隨便

Public LeafData1 As DataTable

Public LeafData2 As DataTable

Public LeafNewRow As DataRow '本次值得一提的是前兩次給你的代碼里都有這行,實(shí)際上這行在前兩次里是沒有用的,這行是添加行時需要的一個行的類,我忘記刪除掉這個了而已,恰好在這次需要使用了,讓你能更好地理解

vb.net excel 怎樣篩選后復(fù)制到sheet2中？

Sub?Macro1()

Columns("A:A").Select

Selection.AutoFilter

ActiveSheet.Range("$A$1:$A$5").AutoFilter?Field:=1,?Criteria1:="1"

Selection.Copy

Sheets("Sheet2").Select

Columns("A:A").Select

ActiveSheet.Paste

End?Sub

你錄制個宏就有代碼了 如上代碼所示

VB。NET怎么把一個表的結(jié)構(gòu)到復(fù)制到另一個表中

個人覺得：樓主所需要達(dá)到的，不應(yīng)該由。net來實(shí)現(xiàn)吧，以下是個人的一些學(xué)習(xí)筆記，或許可以幫助你，看看吧

SQL語句：select .....into....from

1、從B表中讀取數(shù)據(jù)插入到現(xiàn)有的A表：

insert into A select * from B where 條件；

2、新建一個與A表同樣結(jié)構(gòu)的表B，并把A表中滿足條件的數(shù)據(jù)寫入表B：

select * into B from A where 條件

3、根據(jù)一個表A的數(shù)據(jù)，來更新表B的字段值（A,B表可以夸庫）

update B

set B.字段1 =A.字段1，B.字段2=A.字段2

from A inner join B

on A.條件字段=B.條件字段

VB.NET中如何用SQL語句建表（復(fù)制表）？謝謝了！

分類: 電腦/網(wǎng)絡(luò) 程序設(shè)計(jì) 其他編程語言

問題描述:

在SQL數(shù)據(jù)庫里已有一個現(xiàn)成的空數(shù)據(jù)表（只有字段、沒有數(shù)據(jù)），請問高手，怎樣在VB.NET中用SQL語句把該數(shù)據(jù)庫中的那個表復(fù)制一個到該數(shù)據(jù)庫（字段不變、數(shù)據(jù)為空）只是把數(shù)據(jù)表的名改了？

謝謝！謝謝！

解析:

select * into 新表 from 舊表

使用 SELECT INTO 插入行

SELECT INTO 語句創(chuàng)建一個新表，并用 SELECT 的結(jié)果集填充該表。新表的結(jié)構(gòu)由選擇列表中表達(dá)式的特性定義，例如：

SELECT Shippers.*, Link.Address, Link.City,

Link.Region, Link.PostalCode

INTO NewShippers

FROM Shippers

JOIN LinkServer.DB.dbo.Shippers AS Link

ON (Shippers.ShipperID = Link.ShipperID)

SELECT INTO 可將幾個表或視圖中的數(shù)據(jù)組合成一個表。也可用于創(chuàng)建一個包含選自鏈接服務(wù)器的數(shù)據(jù)的新表。
