Mar 19, 2020 ActiveX Data object for MacBook I have purchased Ms Office, and installed in my MacBook Air. I can not run VB enabled Excel file (that runs perfectly fine in my Windows Laptop) as it misses 'Microsoft ActiveX Data objects 2.1 Library'. Microsoft ActiveX Data Objects 2.8 Library; ADO. First, configure ADO. ADO, ActiveX Data Object, is component to connect to the database. There are many kinds of databases but ADO can connect to every databases in the same way. Add ADODB at Preferences dialog in Visual Basic Editor. Open Excel Visual Basic Editor. Microsoft ActiveX Data Objects (ADO) enable your client applications to access and manipulate data from a variety of sources through an OLE DB provider. Its primary benefits are ease of use, high speed, low memory overhead, and a small disk footprint. ADO supports key features for building client/server and Web-based applications. May 19, 2009 Both computers have Microsoft DAO 3.6 Object Library. I don't know if its even the same thing. But when I un-reference the 2.8 and reference the 3.6, the code still won't work. It gets hung up on the same spot. Reference to MS ActiveX Data Objects 2.8 Lib Actually yea I just found it in the other computer. Enabled it and it works fine. Aug 18, 2011 ActiveX Data Objects (ADO) is a collection of software components providing a programmatic interface to access the data sources from client applications. ADO acts as a layer to access any data store in a generic way from the application code. It eliminates the need to possess the knowledge of database implementation and reduces the complexity.
Represents a stream of binary data or text.
Mar 17, 2004 The MDAC 2.8 SDK is for developers who are building applications using ADO, OLE DB, and ODBC. It contains updated documentation, headers, libs and typelibs for x86, IA64 and AMD64 platforms, as well as updated sample applications and developer tools. Microsoft Data Access Components (MDAC) 2.8 Software Development Kit Important! Microsoft ActiveX Data Objects (ADO) enable your client applications to access and manipulate data from a variety of sources through an OLE DB provider. Its primary benefits are ease of use, high speed, low memory overhead, and a small disk footprint.
In tree-structured hierarchies such as a file system or an e-mail system, a Record may have a default binary stream of bits associated with it that contains the contents of the file or the e-mail. A Stream object can be used to manipulate fields or records containing these streams of data. A Stream object can be obtained in these ways:
From a URL pointing to an object (typically a file) containing binary or text data. This object can be a simple document, a Record object representing a structured document, or a folder.
By opening the default Stream object associated with a Record object. You can obtain the default stream associated with a Record object when the Record is opened, to eliminate a round-trip just to open the stream.
By instantiating a Stream object. These Stream objects can be used to store data for the purposes of your application. Unlike a Stream associated with a URL, or the default Stream of a Record, an instantiated Stream has no association with an underlying source by default.
With the methods and properties of a Stream object, you can do the following:
Open a Stream object from a Record or URL with the Open method.
Close a Stream with the Close method.
Input bytes or text to a Stream with the Write and WriteText methods.
Read bytes from the Stream with the Read and ReadText methods.
Write any Stream data still in the ADO buffer to the underlying object with the Flush method.
Copy the contents of a Stream to another Stream with the CopyTo method.
Control how lines are read from the source file with the SkipLinemethod and the LineSeparator property.
Determine the end of stream position with the EOSproperty and SetEOS method.
Save and restore data in files with the SaveToFileand LoadFromFile methods.
Specify the character set used for storing the Stream with the Charset property.
Halt an asynchronous Stream operation with the Cancel method.
Determine the number of bytes in a Stream with the Size property.
Control the current position within a Stream with the Position property.
Determine the type of data in a Stream with the Type property.
Determine the current state of the Stream (closed, open, or executing) with the State property.
Specify the access mode for the Stream with the Mode property.
Note
URLs using the http scheme will automatically invoke the Microsoft OLE DB Provider for Internet Publishing. For more information, see Absolute and Relative URLs.
The Stream object is safe for scripting.

Microsoft Access provides three object models to use in the creation, maintaining, and managing of your Access databases and their related data by using Visual Basic.
ADO contains the objects needed to create, maintain, and delete records in a given datasource.
ADOX provides the Data Definition Language (DDL) objects needed to create a new database and its contained objects in addition to the objects needed to manage security.
Because ADO objects were designed to work with many databases in addition to Microsoft Jet databases, functionality specific to Jet was broken out into the JRO library.
The following table lists the functionality provided by each compared to DAO.
Functionality | DAO | ADO1 | ADOX2 | JRO |
|---|---|---|---|---|
Create Recordsets. | X | X | ||
Edit Startup properties. | X | X** | ||
Support ANSI92 SQL.*** | X | X | ||
Create tables. | X | X | ||
Create new database. | X | X* | ||
Edit existing table properties. | X | X | ||
Create table relationships. | X | X* | ||
Edit security settings. | X | X* | ||
Support for Compression attribute for column data. | X | |||
Edit stored, basic SQL queries or views. | X | X* | ||
Create permanent queries that are accessible only through code. | X* | |||
Create queries accessible through database container/UI and code. | X | |||
Compact/encode database. | X | X4 | ||
Refresh cache. | X | X | ||
Make database replicable. | X | X3 | ||
Make database replicas. | X | X3 | ||
Synchronize replicas. | X3 | |||

Edit table column properties. | X |
* Only available when working with Microsoft Access databases. Future versions of the SQL Provider may provide this functionality in Microsoft Access projects (.adp).
** Only available when working with Access projects.
*** Although the Access database engine does support some ANSI 92 SQL, it is not yet fully ANSI92-compliant.
1 Uses Connection object to reference database.
2 Uses Catalog object to reference database.
3 Uses Replica object to reference database.
4 Uses JetEngine object to reference database.
Note
Unlike DAO, ADO and ADOX objects can perform the marked actions in databases other than Jet as long as the provider for those databases supports that action.
