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 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

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;"

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.

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;" & _ "Password=myPassword;" Note: - xxx.xxx.xxx.xxx is an IP address - "Network Library=DBMSSOCN" tells OLE DB to use TCP/IP rather than Named Pipes (Q238949) - 1433 is the default port number for SQL Server - You can also add "Encrypt=yes" for encryption
