	Access MFC Resources as if they were MFC CFiles

MFC does not provide access to the directory-picking dialog as it does the other Common Dialogs.
You can use the ShBrowseForFolder function; the following two functions demonstrate the simplest way to use it:

void CMyDlg::OnButton1() {
  char Dest[MAX_PATH];
  PickDir("Hello", Dest);
}

bool CMyDlg::PickDir(const char* Prompt, char* Dest) {
// Dest is assumed to be _MAX_PATH characters in length
  BROWSEINFO bi;
  ITEMIDLIST* pItemIDList;
  char Folder[_MAX_PATH];
  memset(&bi, 0, sizeof(bi));
  bi.hwndOwner=m_hWnd;
  bi.pszDisplayName=Folder;
  bi.lpszTitle=Prompt;
  if((pItemIDList=SHBrowseForFolder(&bi))==NULL) return false;
  SHGetPathFromIDList(pItemIDList, Dest);
  return true;
}

There is also Callback functionality available - but most people find that confusing, so it is encapsulated it in a class (CBrowseForFolder) that should help and provided a couple of useful example classes.

CBrowseForDirectory demonstrates the usage of CBrowseForFolder and gets the user to pick a valid Directory (ie not the "Recycle Bin" or "My Computer" etc).
CBrowseForFile also demonstrates the usage of CBrowseForFolder and gets the user to tell us where a particular file is by only enabling the [OK] button when a folder containing a particular file is selected.
Look at the CBrowseForFolder class to see the virtual functions you can override to receive information,
and the functions you can use to control the Dialog Box (the ones that use SendMessage).

This file also contains a horrible little class that encapsulates the revolting code necessary to find the PIDL of a path...
You shouldn't need CItemIDList because there is already a SelectItem function that takes a path, but it is included to show how to do it.
