well I finally found how to view the ssi extension in design view thanks to all
your help!
it was here

as you said)
http://www.macromedia.com/support/dreamweaver/ts/documents/add_ext_mx.htm
under-The MMDocumentTypes.xml file
I do want to say one thing...
I am not an expert user in dreamweavermx2004 ( I use frontpage ) and my client
using dwmx2004 is only a beginner. I had to convert a frontpage site to dw so
she could use it. All the frontpage "include pages" had to be converted to
dreamweavers way. To do this, I used the macromedia reference:
http://www.macromedia.com/support/dreamweaver/ts/documents/create_ssi.htm as
the source for how to insert ssi in dreamweaver. I followed it exactly using
the extension they recommend -ssi. nowhere in there does it mention you won't
be able to view or change your ssi files in design view or how to add the ssi
extension to the MMDocumentTypes.xml file. It seems a little ridiculous they
used the ssi extension as the example failing to fill you in on this. why use
it as the example? why not just have the ssi extension already in the
MMDocumentTypes.xml file ?
anyways thanks for all your help but it really was alot of unnecessary
confusion...should have been there already or the article on how to do this
should not use the ssi extension as the example.
