This article assumes that you are familiar with Microsoft Internet Information Server (IIS) and with creating Active Server Pages (ASP) applications using the programming tools provided with Microsoft Internet Information Server or Microsoft Visual InterDev. Additionally, it assumes that you are familiar with HTML. For more information about Microsoft Information Server and Active Server Pages, see the following Web site:

SUMMARY

This article describes how to use ActiveX Data Objects (ADO) on an Active Server Page (ASP) to access data in a Microsoft Visual FoxPro database.

MORE INFORMATION

To run Active Server Pages, you must have access to a computer that is running Microsoft Internet Information Server (IIS) version 3.0 or a later version of IIS. To access a Visual FoxPro database through ADO, you must have the latest Visual FoxPro ODBC driver.
For additional information about how to obtain this driver, click the following article number to view the article in the Microsoft Knowledge Base:
277772  (http://support.microsoft.com/kb/277772/ ) Visual FoxPro ODBC Driver not included in MDAC 2.6 and later
Note If your database or tables use any of the features that were introduced in Visual FoxPro 7.0 or a later version of Visual FoxPro, you must use the VFP OLE DB Provider to connect to the data. To obtain the VFP OLE DB Provider, visit the following Microsoft Developer Network (MSDN) Web site:
http://www.msdn.microsoft.com/vfoxpro (http://www.msdn.microsoft.com/vfoxpro)
To set up ODBC to access your database over the Internet Information Server, use one of the following methods:
  • Create a System Data Source on the IIS Server computer that points to the database.
  • Create a File Data Source that points to the database. If you create this Active Server Page in a Database Project in Visual InterDev Studio, if you add a connection that uses a file data source, it includes the data source information in the Global.asa file. This can then be distributed with the Active Server Page.
  • When creating the connection object through VBScript, include the connect string when running the Open method (example below).

Limitations

Recordsets, or cursors, generated by Visual FoxPro through the Visual FoxPro ODBC Driver must be of type STATIC, or READONLY. The Visual FoxPro ODBC driver does not support the KEYSET, or DYNAMIC cursor types.

Example

This example does not use a specific data source. The connect string is being specified in the connection object's Open method. If you do wish to create and use a Data source, ensure it is a System Data Source on the Microsoft Internet Information Server computer.

Remember

Change the SourceDB setting to reflect the Tastrade.dbc on the test system. Ensure the Visual FoxPro ODBC driver version 6.01.8629.01 or later is installed on the Microsoft Information Server where this Active Server Page is stored. Please see article reference above for availability options of this driver.
