Installing ADO

I l @ ve RuBoard

ADO is installed by default in products such as Microsoft SQL Server and Microsoft Office. You can also download ADO from http://www.microsoft.com/data/.

A word of warning with ADO: It is not backward-compatible , so if you install the most recent version of ADO and then you install an application that installs a later version of ADO, you could end up with a very messy computer. This is classic "DLL hell" (see Chapter 7), in which you end up with different versions of the same COM objects. Sorting out this mess is often very difficult (and I speak from experience). As a general rule, avoid very recent versions of ADO as much as you can.
