Re: Folder selecting dialog (once again)

I know, this question is coming up from time to time.

I'm looking for a folder selcetion dialog. I know there
are two possible approches, a SHBrowseForFolder based one
and a CFileDialog resp. GetSaveFileName based one.

My app will write some files to a directory that does not
yet exist. So the situation can be compared with an installer,
which suggests a directory name, and the directory does
not yet exist. If it does already exist, then the user shall
be warned that the files in that directoy will be overwritten.
This is rather opposite to the usual situation where you will
be prompted if the choosen directory does not exist yet and
is about to be created.

For that reason I don't think that SHBrowseForFolder will suit
my needs. I don't see how SHBrowseForFolder can display a name
of a directory not existing yet. So I took a look at all the
CFiledialog based examples at Codeguru and Codeproject. Again
I did not find any that really does what I want. I saw some
installers with a directory choosing CFileDialog. If the
suggested directory does not yet exist it is shown in the
listview in a different color. that would be what I want, but I
have no idea how they achive that.

At codeguru I fond an interesting atricle using a hook.
http://www.codeproject.com/dialog/customize_dialog.asp
In this article the author tries to hide all directories
by using a message hook. What I want is the opposite.
Unfortunately I do not understand what messages (sent
by the listview/comboboxes/... I would have to catch.

Could anyone point me to the right direction?
