在VB中怎样读取Excel中保存的数据?

[lihonggen0]

引用Excel 对象

Dim xlApp As Excel.Application
Dim xlBook As Excel.Workbook
Dim xlSheet As Excel.Worksheet

Set xlApp = CreateObject("Excel.Application")
Set xlBook = xlApp.Workbooks.Open(....
Set xlSheet = xlBook.Worksheets(1)
xlSheet.Cells(1, 4).Value = "aaa"

我说一种dao的方法（也可用ado）
假如excel数据
male female children teens
11 cc 78 ee
22 xx 33 ff
45 uu 56 oo
用ISAM第一行略过
在excel中定义名称（插入－名称－定义）
名称范围 : myRange1

male female children teens

名称范围 : myRange2

11 cc 78 ee
22 xx 33 ff
45 uu 56 oo

private Sub Command_click1

im dbtmp As DAO.Database
im tblObj As DAO.TableDef
im rs As DAO.Recordset

et dbtmp = OpenDatabase_
("<complete path>\test.xls", False, True, "Excel 8.0;")

DoEvents

Set rs = dbtmp.OpenRecordset("select * from `myRange2`")
While Not rs.EOF
For x = 0 To rs.Fields.Count - 1
Debug.Print rs.Fields(x).Value
Next
rs.MoveNext
Wend
End Sub

在myRange2两边加'号.

结果

11
cc
78
ee
22
xx
33
ff
45
uu
56
oo

ado方法
Dim adoConnection As New ADODB.Connection
Dim adoRecordset As New ADODB.Recordset
'OLE DB + ODBC Driver 方式:
'adoConnection.Open "Data Provider=MSDASQL.1;driver=Microsoft Excel Driver (*.xls);DBQ=e:\temp\book2.xls"
'Microsoft.Jet.OLEDB.4.0 方式,(建议)
adoConnection.Open "Provider=Microsoft.Jet.OLEDB.4.0;Persist Security Info=False;Data Source=e:\temp\book2.xls;Extended Properties='Excel 8.0;HDR=Yes'"

adoRecordset.Open "select * from [sheet1$]", adoConnection, adOpenKeyset, adLockOptimistic
Debug.Print adoRecordset.RecordCount
Dim i As Integer
Do Until adoRecordset.EOF
For i = 0 To adoRecordset.Fields.Count - 1
Debug.Print adoRecordset.Fields.Item(0).Name
Debug.Print adoRecordset.Fields.Item(0).Value
Next i
adoRecordset.MoveNext
Loop

'注: OLE DB + ODBC Driver 方式不支持以下语句,但 Microsoft.Jet.OLEDB.4.0 方式支持!
adoConnection.Execute "insert into [sheet1$](F1) values(3)"
adoRecordset.AddNew Array("f1", "f2", "f3", "f4"), Array(1, 2, 3, 4)

可以使用ado直接调用EXCEL的数据，而不需要使用ACCESS。
Dim oConn As New ADODB.Connection
Dim oRS As New ADODB.Recordset
oConn.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=C:\Book1.xls;" & _
"Extended Properties=""Excel 8.0;"""
oRS.Open "Select * from [Sheet1$]", oConn, adOpenStatic '打开Sheet1，也可以是定义的名称，或一个Range。
..
..
..
oRS.Close
oConn.Close
更具体的方法可以参考微软的Knowledge Base的文章：“Q278973 xcelADO Demonstrates How To Read/Write Data in Excel Workbooks”。
用这个方法调用EXCEL数据是非常快的。

能否用VB的ADO的方法访问Excel文件,如果能该怎样实现？

Dim adoConnection As New ADODB.Connection
Dim adoRecordset As New ADODB.Recordset
'OLE DB + ODBC Driver 方式:
'adoConnection.Open "Data Provider=MSDASQL.1;driver=Microsoft Excel Driver (*.xls);DBQ=e:\temp\book2.xls"
'Microsoft.Jet.OLEDB.4.0 方式,(建议)
adoConnection.Open "Provider=Microsoft.Jet.OLEDB.4.0;Persist Security Info=False;Data Source=e:\temp\book2.xls;Extended Properties='Excel 8.0;HDR=Yes'"

adoRecordset.Open "select * from [sheet1$]", adoConnection, adOpenKeyset, adLockOptimistic
Debug.Print adoRecordset.RecordCount
Dim i As Integer
Do Until adoRecordset.EOF
For i = 0 To adoRecordset.Fields.Count - 1
Debug.Print adoRecordset.Fields.Item(0).Name
Debug.Print adoRecordset.Fields.Item(0).Value
Next i
adoRecordset.MoveNext
Loop

'注: OLE DB + ODBC Driver 方式不支持以下语句,但 Microsoft.Jet.OLEDB.4.0 方式支持!
adoConnection.Execute "insert into [sheet1$](F1) values(3)"
adoRecordset.AddNew Array("f1", "f2", "f3", "f4"), Array(1, 2, 3, 4)
