This example uses the Open and Close methods on both Recordset and Connection objects that have been opened.

Use the following example in an Active Server Page (ASP). Use Find to locate the file Adovbs.inc and place it in the directory you plan to use. Cut and paste the following code into Notepad or another text editor, and save it as OpenVBS.asp. You can view the result in any browser.
