How to connect to Excel ?

P: n/a
I connect to mdb file using the following codes. How should I modify it if I
want to connect to Excel instead ?
<%@ Import Namespace="System.Data.OleDb" %>
<%
Dim conAuthors As OleDbConnection
Dim cmdSelectAuthors As OleDbCommand
Dim dtrAuthors As OleDbDataReader

conAuthors = New OleDbConnection(
"PROVIDER=Microsoft.Jet.OLEDB.4.0;DATA
Source=C:\Inetpub\wwwroot\ASPX\Authors.mdb" )
conAuthors.Open()
cmdSelectAuthors = New OleDbCommand( "Select au_lname From Authors",
conAuthors )
dtrAuthors = cmdSelectAuthors.ExecuteReader()
While dtrAuthors.Read()
Response.Write( "<li>" )
Response.Write( dtrAuthors( "au_lname" ) )
End While
dtrAuthors.Close()
conAuthors.Close()

Hi Dear hkappleorange,
Try these 3 things

1. OLEDB
------------------------------------------------------------------------------------------------
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\MyExcel.xls;Extended
Properties=""Excel 8.0;HDR=Yes;IMEX=1"""

"HDR=Yes;" indicates that the first row contains columnnames, not data

"IMEX=1;" tells the driver to always read "intermixed" data columns as text
TIP! SQL syntax: "SELECT * FROM [sheet1$]" - i.e. worksheet name followed by
a "$" and wrapped in "[" "]" brackets.
------------------------------------------------------------------------------------------

2. ODBC
------------------------------------------------------------------------------------------------

Driver={Microsoft Excel Driver
(*.xls)};DriverId=790;Dbq=C:\MyExcel.xls;DefaultDi r=c:\mypath;"

TIP! SQL syntax: "SELECT * FROM [sheet1$]" - i.e. worksheet name followed by
a "$" and wrapped in "[" "]" brackets

------------------------------------------------------------------------------------------------

3.

ODBC Driver for Excel
===================

oConn.Open "Driver={Microsoft Excel Driver (*.xls)};" & _
"DriverId=790;" & _
"Dbq=c:\somepath\mySpreadsheet.xls;" & _
"DefaultDir=c:\somepath"

OLE DB Provider for Microsoft Jet
For standard security

oConn.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=c:\somepath\myDb.mdb;"
If using a Workgroup (System Database)

oConn.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=c:\somepath\mydb.mdb;" & _
"Jet OLEDB:System Database=MySystem.mdw", _
"myUsername", "myPassword"
Note, remember to convert both the MDB and the MDW to the 4.0
database format when using the 4.0 OLE DB Provider.
If MDB has a database password

oConn.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=c:\somepath\mydb.mdb;" & _
"Jet OLEDB:Database Password=MyDbPassword", _
"myUsername", "myPassword"

If want to open up the MDB exclusively

oConn.Mode = adModeShareExclusive
oConn.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=c:\somepath\myDb.mdb;"
If MDB is located on a network share

oConn.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=\\myServer\myShare\myPath\myDb.mdb"

If MDB is located on a remote machine

- Or use an XML Web Service via SOAP Toolkit or .NET
- Or upgrade to SQL Server and use an IP connection string


If you don't know the path to the MDB (using ASP)

<% ' ASP server-side code
oConn.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=" & Server.MapPath(".") & "\db\myDb.mdb;" & _
%>
This assumes the MDB is in a sub-directory called "db" directory, which has
Read/Write permissions for the Web site identity account (e.g. IUSR_XXXXX).
If you don't know the path to the MDB (using VB)

oConn.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=" & App.Path & "\myDb.mdb;" & _
"User Id=admin;" & _
"Password="
This assumes the MDB is in the same directory where the application is
running.

For more information, see: OLE DB Provider for Microsoft Jet, Q191754, and
Q225048

Note: Microsoft.Jet.OLEDB.3.51 only gets installed by MDAC 2.0. Q197902
Note: MDAC 2.6 and 2.7 do not contain any of the JET components. Q271908
and Q239114

You can also open an Excel Spreadsheet using the JET OLE DB Provider
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

oConn.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=c:\somepath\mySpreadsheet.xls;" & _
"Extended Properties=""Excel 8.0;HDR=Yes"""

Where "HDR=Yes" means that there is a header row in the cell range
(or named range), so the provider will not include the first row of the
selection into the recordset. If "HDR=No", then the provider will include
the first row of the cell range (or named ranged) into the recordset.
