SHBrowserForFolder : Browse for a folder

There is no easy way to browse a directory in VC++ like in VB or or other visual tools. SHBrowseForFolder
Shell API can be used to do so. SHBrowseForFolder  Displays a dialog box that enables the user to select a
shell folder.

LPITEMIDLIST SHBrowseForFolder( LPBROWSEINFO lpbi );
lpbi
[in] Pointer to a BROWSEINFO structure that contains information used to display the dialog box.

SHBrowseForFolder  returns a pointer to an ITEMIDLIST structure (PIDL) that specifies the location of the
selected folder relative to the root of the namespace.

You must initialize COM using CoInitializeEx with the COINIT_APARTMENTTHREADED flag on dwCoInit set prior to
calling SHBrowseForFolder. You can also use CoInitialize or OLEInitialize, which always use apartment threading.

The calling application is responsible for freeing the returned PIDL with the shell allocator's IMalloc::Free
method. To get a handle to the shell allocator's IMalloc interface.
