How To Open Document Of Unknown Type From VBA?

P: n/a
I've got a UNC.

It's something like H:\CDL\Attachments\Deal000023.InitialOffering.doc.

I want to feed that UNC to MS Windows and let Windows worry about selecting
which application to use to open it. If there's no app defined for that UNC's
particular suffix, that's ok... we'll live with it.

Seems like a FileSystemObject should be able to do this, but I can't find such a
method.

'Shell' wants an executable.

Maybe an API call?

Hehe.

I have some code (not on me right now) that will lookup the registry
and get the program associated with the filename extension. Not sure if
it'd work any better/worse than the above....

The code quoted is the correct way to do it (in Win32 terms), it works by
looking in the registry for the file extension and then looks at the verb
(passed in lpOperation) to carry out the appropriate action for the file.

In the example below as lpOperation is set to vbNullstring this means that
it will perorm the default operation, this is generally "Open".

How does this differ from FollowHyperLink?
Is one less efficient?
Will one find more run operations with the one than the other?
Something else?

Lyle,
I wasn't trying to say this is better than FollowHyperLink, I was trying to
make the point that ShellExecute does the looking up in the registry that
one poster said they had code for.

Answering your questions:-
I wouldn't know, but I would guess the FollowHyperLink mehod to some
extent uses ShellExecute to find the registered app.
Quite possibly but considering the use both methods are put to, this is
almost certainly irrelevant.
IIRC FollowHyperLink attempts to use IE if it can't find the registered
app, whereas if you use ShellExecute you have to build in a method of your
own to handle this.
Almost certanly.
