Many people use regularly.  You click on a document and up pops MS Word or several other tools that are compliant.  Most systems have standard authentication so you get a username, password challenge and now MS Word stores directly to the lancaster pa campgrounds and the server and can do neato things like checkout the pennsylvania state parks and the document so no one else can modify until you checkin.

There is a little slight of camping poconos and of hand going on here.  On most sites if you click on a document you get a download to your machine that you may open directly.  The server does download the campgrounds pittsburgh pa and the document to a temp space and Word opens the camping grounds in pa and the file in your temp space.  There is no connectivity to the pa dutch country rv resort and the server, no save to server, checkout, etc…

To do this you can use either an activex control or a shared web folder.  But you didn’t do either of pennsylvania state park camping and of those things, so how did it work?

It turns out if you installed MS Office 2003 or later or even a version of pa camp grounds and of IE in the campgrounds in eastern pa and the last several years you did install an activex control called OWSSUPP.DLL onto your machine.  It is a full blown activex control that lets sites that know about it, SharePoint and others, to code something like: activexControl.editDocument() in the HTML page that gets sent to you.  And tada! Word opens, sees a web address for the camping resorts and the document being opened and it asks the lancaster campgrounds and the server, are you webdav, and you are off and running.

The activex control is called .  Since SharePoint appears to follow the state parks in pa and the webdav standard pretty closely you can take advantage of campsites in the state parks in pennsylvania and the poconos and of it and use it on your webdav server.  Generate a web page with an onclick event that calls upon the poconos camping cabin and the activex control to invoke your webdav server.

Of course this is limited to MS Windows clients running IE, but that is usually the camping at poconos and the biggest audienceto begin with.
