.dll versus .ocx

[DS]

I have an Access database for processing credit cards. There is a choice of
using .com(.dll) or Control (.ocx). Is here an upside or a downside in
using one or another? Is one more stable? Is one more vanilla than the
other? Also to take it a step further will Winhttp replace any of these?
Is Winhttp stable? Any Suggestions or comments welcomed. Thanks.

Use DLLs if they work just by being installed in your front end
applications folder. (Such as "C:\Documents and
Settings\ttoews\Application Data\<your app name>"

OCXs require registering which means admin rights. If the DLL works
in your app folder it doesn't require registering and can be updated
any time by you.

This is exactly how Lebans PDF printing DLLs work and it's terribly
convenient.
