BROWSEINFO & pidlRoot

[Lamblion]

I can't figure out how to get the string of a folder location into pidlRoot
of a BROWSEINFO structure for SHBrowseForFolder(). I think I have to call
another function first, but I don't know how to convert that into a
PCIDLIST_ABSOLUTE. A short example would be appreciated.

Use IShellFolder::ParseDisplayName to convert your folder string to a
PIDL:

Thangks, guys. I tried both, and the second one is really simple. However,
the problem I have now is that if I set a subdirectory, it will not allow me
to choose any folders above it.

I would like the dialog to open at a selected folder, but also be able to
move higher up instead of only down.

If you are asking how to set the initial folder in the browser, here's how:

Basically you send it BFFM_SETSELECTION from inside the callback function.

Thanks, Ivo. That is exactly what I was looking for.

Use SHGetDesktopFolder() to get the top-level IShellFolder interface for the
Desktop namespace, then pass the string to its ParseDisplayName() method.

That is what pidlRoot is supposed to do. It is the "root" of the dialog.
You can only select items underneath the "root" folder.

Then you need to set the pidlRoot to something higher up the hierarchy (such
as the PIDL for the CSIDL_DRIVES folder), and then use a callback function
(specified in the BROWSEINFO.lpfn member) to send a BFFM_SETSELECTION
message to the dialog when the callback receives the BFFM_INITIALIZED
notification.
