GetOpenFileName lpstrInitialDir (directory)... not working for URL (SharePoint)

Question

I bring up a GetOpenFileName dialog, enter a URL to a SharePoint sever, and it lets me browse that server using the Web Client Service (WebDAV mini-redirector). I am trying to get the initial directory to come up as that URL, but it seems to ignore it (using OPENFILENAME struct's lpstrInitialDir. Local paths work fine.

EDIT: Paul requested the form of the URL: it's http://doc.name.com I've also tried a trailing slash (both flavors) to see if that made a difference (saw some reference to that in another posted question). It didn't seem to.

EDIT2: This does work if I use the WebDAV address instead of the HTTP URL (i.e., \doc.name.com\DavWWWRoot. This doesn't solve my problem, as it's not a view of the site that users will recognize and will have difficulty working with.

Answer 1

If your application is for vista, you can use the IFileOpenDialog, which lets you use an IShellItem as the default location, and it should be pretty easy to create a shell item that points to the sharepoint URL.
