With rngStart.Rows(1)
.Font.Bold = True
Sh1.Range("A1", "C1").Font.Color = RGB(112, 220, 21)
Sh1.Range("A1", "C1").Borders.LineStyle = xlContinuous
.Cells(, 1) = "桩 号"
.Cells(, 2) = "X（N）坐标"
.Cells(, 3) = "Y（E）坐标"

1：读取。

1、在VB中，建立一个FORM，在其上放置两个命令按钮，将Command1的Caption属性改为EXCEL，Command2的Caption属性改为End。然后在其中输入如下程序：

Dim xlApp As Excel.Application '定义EXCEL类
Dim xlBook As Excel.Workbook '定义工件簿类
Dim xlsheet As Excel.Worksheet '定义工作表类
Private Sub Command1_Click() '打开EXCEL过程
If Dir("D:\temp\excel.bz") = "" Then '判断EXCEL是否打开
Set xlApp = CreateObject("Excel.Application") '创建EXCEL应用类
xlApp.Visible = True '设置EXCEL可见
Set xlBook = xlApp.Workbooks.Open("D:\temp\bb.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
xlsheet.Cells(1, 1) = "abc" '给单元格1行驶列赋值
xlBook.RunAutoMacros (xlAutoOpen) 运行EXCEL中的启动宏
Else
MsgBox ("EXCEL已打开")
End If
End Sub

Private Sub Command2_Click()
If Dir("D:\temp\excel.bz") <> "" Then '由VB关闭EXCEL
xlBook.RunAutoMacros (xlAutoClose) '执行EXCEL关闭宏
xlBook.Close (True) '关闭EXCEL工作簿
xlApp.Quit '关闭EXCEL
End If
Set xlApp = Nothing '释放EXCEL对象
End
End Sub

2、在D盘根目录上建立一个名为Temp的子目录，在Temp目录下建立一个名为"bb.xls"的EXCEL文件。

3、在"bb.xls"中打开Visual Basic编辑器，在工程窗口中点鼠标键选择插入模块，在模块中输入入下程序存盘：

Sub auto_open()
Open "d:\temp\excel.bz" For Output As #1 '写标志文件
Close #1
End Sub
Sub auto_close()
Kill "d:\temp\excel.bz" '删除标志文件
End Sub

4、运行VB程序，点击EXCEL按钮可以打开EXCEL系统，打开EXCEL系统后，VB程序和EXCEL分别属两个不同的应用系统，均可同时进行操作，由于系统加了判断，因此在VB程序中重复点击EXCEL按钮时会提示EXCEL已打开。如果在EXCEL中关闭EXCEL后再点EXCEL按钮，则会重新打开EXCEL。而无论EXCEL打开与否，通过VB程序均可关闭EXCEL。

2：写入。
Excel导入sql:

'引用ADO(Microsoft ActiveX Data Objects 2.X Library)
Private Sub Command2_Click()
Dim cn As New ADODB.Connection
cn.ConnectionString = "Provider=SQLOLEDB.1;Persist Security Info=False;User ID=sa;Password=123;Initial Catalog=dataBase001;Data Source=mySERVICE"
cn.CursorLocation = adUseClient
cn.Open
cn.Execute "select * into table4 from OpenRowSet('microsoft.jet.oledb.4.0','Excel 8.0;HDR=Yes;database=d:\temp\bb.xls;','select * from [Sheet1$]')"
cn.Close
Set cn=Nothing
End Sub
