This is Tim in regards to your
response to message 4 of your post today.

Yes I have the closing quote, and I have most definitely already
tried opening the file in admodereadwrite. If it were that trivial a
problem I wouldn't have posted. I will include here all the actual
code I am trying (which works  in a non-enhanced folder...)

Set objDoc = New PKMCDO.KnowledgeDocument
objDoc.PromptToAuthenticate = False
objDoc.DataSource.Open rs.Fields(2).Value, oConn,
adModeReadWrite
objDoc.ContentClass = "urn:content-classes:" &
txtContentClass.Text
objDoc.DataSource.Save

(THIS WORKS IN A NON ENHANCED FOLDER BUT WHEN I TRY IN AN ENHANCED
FOLDER, THATS WHEN IT PROMPTS FOR A NETWORK PASSWORD AND NOTHING
WORKS)

Sorry, I normally don't even bother reading the list as there seem to be a lot
of problems of that sort. : )

I'm at a bit of a loss. Where is this code running? In a web-part, or a script?
Who's running it (permissions)? Is everything on the same server?

You may wish to try getting a handle to the latest version of the document, and
modifying that rather than the base version:

'open doc
oDocument.DataSource.Open strDocumentURL

'bind a rs to the document's version status (create a KnowledgeVersion first. .
.)
oRs = oVersion.VersionStatus(oDocument)

'rebind
oDocument.DataSource.Open oRs("DAV:href"), , adModeReadWrite

'set content-class
'save as normal

Hope that helps. I'm not sure exactly what the mechanism is for how all of this
works. I've had nothing but headaches with undefined errors, bizarre ways of
accomplishing tasks, etc. In the end, trial-and-error seems to win though.
