_
          "SourceType=DBC;" & _
          "SourceDB=c:\somepath\mySourceDb.dbc;" & _
          "Exclusive=No;"

Without a database container (Free Table Directory):

oConn.Open "Driver={Microsoft Visual FoxPro Driver};" & _
          "SourceType=DBF;" & _
          "SourceDB=c:\somepath\mySourceDbFolder;" & _
          "Exclusive=No;"


For more information, see: Visual FoxPro ODBC Driver and Q165492




OLE DB Data Link Connections
Data Link File (UDL)
 
For Absolute Path:

oConn.Open "File Name=c:\somepath\myDatabaseName.udl;"

For Relative Path:

oConn.Open "File Name=myDatabaseName.udl;"
 

For more information, see: HOWTO: Use Data Link Files with ADO

Note: Windows 2000 no longer contains the "New | Microsoft Data Link" menu 
anymore. You can add the Data Link menu back in the menu list by running the
"C:\Program Files\Common Files\System\Ole DB\newudl.reg" reg file,
then right-click on the desktop and select "New | Microsoft Data Link" menu. 
Or you can also create a Data Link file by creating a text file and change it''''s
file extension to ".udl", then double-click the file.




OLE DB Provider Connections
OLE DB Provider for AS/400
 
oConn.Open "Provider=IBMDA400;" & _
          "Data source=myAS400;"
          "User Id=myUsername;" & _
          "Password=myPassword;"

For more information, see:  A Fast Path to AS/400 Client/Server


OLE DB Provider for Active Directory Service
 
oConn.Open "Provider=ADSDSOObject;" & _
          "User Id=myUsername;" & _
          "Password=myPassword;"
 

For more information, see: Microsoft OLE DB Provider for Microsoft Active Directory Service


OLE DB Provider for DB2
 
oConn.Open = "Provider=DB2OLEDB;" &
           "Network Transport Library=TCPIP;" &
           "Network Address=MyServer;" & _
           "Package Collection=MyPackage;" &
           "Host CCSID=1142"
           "Initial Catalog=MyDB;" &
           "User ID=MyUsername;" & _
           "Password=MyPassword;"

For more information, see: OLE DB Provider for DB2
and INF: Configuring Data Sources for the Microsoft OLE DB Provider for DB2


OLE DB Provider for Index Server
 
oConn.Open "Provider=msidxs;" & _
          "Data source=MyCatalog;"
 

For more information, see: Microsoft OLE DB Provider for Microsoft Indexing Service


OLE DB Provider for Internet Publishing
 
oConn.Open "Provider=MSDAIPP.DSO;" & _
      "Data Source=http://mywebsite/myDir;" & _
      "User Id=myUsername;" & _
      "Password=myPassword;"
 

For more information, see: Microsoft OLE DB Provider for Internet Publishing and Q245359


OLE DB Provider for Microsoft Jet
 
For standard security:

oConn.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _
          "Data Source=c:\somepath\myDb.mdb;" & _
          "User Id=admin;" & _
          "Password=;"

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;", _
          "admin", ""

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;", _
          "admin", ""

If MDB is located on a network share:

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

If want to open up the Access database exclusively:

oConn.Mode = adModeShareExclusive
oConn.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _
          "Data Source=c:\somepath\myDb.mdb;" & _
          "User Id=admin;" & _
          "Password=;"


For more information, see: OLE DB Provider for Microsoft Jet, Q191754, Q225048, Q239114, and Q271908


You can also open an Excel Spreadsheet using the "OLE DB Provider for Microsoft Jet"

oConn.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _
          "Data Source=c:\somepath\myExcelSpreadsheet.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.

For more information, see: Q278973


You can also open a Text File using the "OLE DB Provider for Microsoft Jet"

oConn.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _
          "Data Source=c:\somepath\;" & _
          "Extended Properties=""text;HDR=Yes;FMT=Delimited;"";"

'''' Then open a recordset based on a select on the actual file
oRs.Open "Select * From MyTextFile.txt", oConn, adOpenStatic, adLockReadOnly, adCmdText

For more information, see: Q262537


OLE DB Provider for ODBC Databases
 
For Access (Jet):

oConn.Open "Provider=MSDASQL;" & _
          "Driver={Microsoft Access Driver (*.mdb)};" & _
          "Dbq=c:\somepath\mydb.mdb;" & _
          "Uid=myUsername;" & _
          "Pwd=myPassword;"

For SQL Server:

oConn.Open "Provider=MSDASQL;" & _
          "Driver={SQL Server};" & _
          "Server=myServerName;" & _
          "Database=myDatabaseName;" & _
          "Uid=myUsername;" & _
          "Pwd=myPassword;"

For more information, see: Microsoft OLE DB Provider for ODBC


OLE DB Provider for Oracle (from Microsoft)
 
oConn.Open "Provider=msdaora;" & _
          "Data Source=MyOracleDB;" & _
          "User Id=myUsername;" & _
          "Password=myPassword;"

For more information, see: Microsoft OLE DB Provider for Oracle


OLE DB Provider for Oracle (from Oracle)
 
For Standard Security:

oConn.Open "Provider=OraOLEDB.Oracle;" & _
          "Data Source=MyOracleDB;" & _
          "User Id=myUsername;" & _
          "Password=myPassword;"

For a Trusted Connection:

oConn.Open "Provider=OraOLEDB.Oracle;" & _
          "Data Source=MyOracleDB;" & _
          "User Id=/;" & _
          "Password=;"
'''' Or

oConn.Open "Provider=OraOLEDB.Oracle;" & _
          "Data Source=MyOracleDB;" & _
          "OSAuthent=1;"
 

Note: "Data Source=" must be set to the appropriate Net8 name which is known to the naming method in use. For example, for Local Naming, it is the alias in the tnsnames.ora file; for Oracle Names, it is the Net8 Service Name.

For more information, see: Connecting to an Oracle Database
(Note, if you get a Logon dialog, then click Cancel, then perform a one-time free signup with Oracle''''s TechNet system)


OLE DB Provider for Simple Provider
 
The Microsoft OLE DB Simple Provider (OSP) allows ADO to access any data for which a provider has
been written using the OLE DB Simple Provider Toolkit. Simple providers are intended to access data
sources that require only fundamental OLE DB support, such as in-memory arrays or XML documents.

OSP in MDAC 2.6 has been enhanced to support opening hierarchical ADO Recordsets over arbitrary
XML files. These XML files may contain the ADO XML persistence schema, but it is not required. This
has been implemented by connecting the OSP to the MSXML2.DLL, therefore MSXML2.DLL or newer is
required.

oConn.Open "Provider=MSDAOSP;" & _
          "Data Source=MSXML2.DSOControl.2.6;"

oRS.Open "http://WebServer/VirtualRoot/MyXMLFile.xml", oConn


For more information, see: Microsoft OLE DB Simple Provider


OLE DB Provider for SQL Server
 
For Standard Security:

oConn.Open "Provider=sqloledb;" & _
          "Data Source=myServerName;" & _
          "Initial Catalog=myDatabaseName;" & _
          "User Id=myUsername;" & _
          "Password=myPassword;"

For a Trusted Connection:

oConn.Open "Provider=sqloledb;" & _
          "Data Source=myServerName;" & _
          "Initial Catalog=myDatabaseName;" & _
          "Integrated Security=SSPI;"

To connect to a "Named Instance" (SQL Server 2000)

oConn.Open "Provider=sqloledb;" & _
          "Data Source=myServerName\Inst2;" & _
          "Initial Catalog=myDatabaseName;" & _
          "User Id=myUsername;" & _
          "Password=myPassword;"

To Prompt user for username and password:

oConn.Provider = "sqloledb"
oConn.Properties("Prompt") = adPromptAlways
oConn.Open "Data Source=myServerName;" & _
          "Initial Catalog=myDatabaseName;"

To connect via an IP address:

oConn.Open "Provider=sqloledb;" & _
          "Data Source=xxx.xxx.xxx.xxx,1433;" & _
          "Network Library=DBMSSOCN;" & _
          "Initial Catalog=myDatabaseName;" & _
          "User ID=myUsername;" & _
