A 'browse for folder' dialog?

[reanimated]

Hi all,

Are there any system supplied dialogs that will allow you to browse for a folder/directory? (like in winamp when you add a directory you get a dialog that just shows the folders on a tree).

thanks.

SHBrowseForFolder is the function you're looking for. Requires shlobj.h, shell32.lib and an awful lot of stupid shell programming. You'll need at least SHGetPathFromIDList to get a proper path, or SHGetDesktopFolder in case you're interested in browsing the shell namespace's representation of whatever is selected.

Thanks for that!

CoTaskMemFree(pidl);

cool, didn't know about that one.

should the program be CoUninitialzise()'ing to?

Looks like your problem's solved, but I'm attaching a class called CFolderDialog that you might find useful. Instead of a tree control (something I'm absolutely not a fan of), it looks like a standard CFileDialog (it is derived from it) but allows you to browse for files, folders, or both. It's not very well thrown together, but it works like a charm. It is originally from CodeGuru, but I threw some fixes in myself (as ugly as they may be).
