Eric Vegter recently reminded me of a tip I published a while ago regarding the ADOVBS.INC file, which contains all the constants used with ADO. Instead of including this file (which makes your ASP file quite a bit larger), you can add this line of HTML to your pages:
<!-- METADATA TYPE="typelib" FILE="C:\Program files\Common Files\System\ado\msado15.dll" -->
This will reference the ADO DLL on your web server. You’ll need to make sure the DLL is located where this code references, but this is the standard install directory for the library. Using this method saves you from having to load the adovbs.inc file into every ASP page.
Thanks for the tip, Eric.
