Developing for Word 2003 and 2007

[Derek Reed]

Hi I am new to developing add-in's so i sure these questions have been asked
before but I have been unable to find them.

I looking to replace a very old extension to Word (started in pre Word 97
days) written in a nasty combination of VBA and calls into DLL's, with a COM
add-in. At this point I am looking at using the IDTExtensibility2 interface,
as I am not sure we want to move to managed code yet.

The question is, will a COM addin built against Office 2003 run with 2007,
or does it need to be rebuilt?

Thanks in advance
Derek

It's likely to work fine. I built one for Word 2003 that worked as-is with
Word 2007, including a custom toolbar (which Word 2007 supports on an
"Addin" ribbon tab).

Hello Derek,

It will work due to backward compatibility of Office type libraries. You can
use late binding to access 2007 features.
