Answer:

The following example demonstrates using the SHBrowseForFolder()
function to allow the user to select a given directory object.

var
  TitleName : string;
  lpItemID : PItemIDList;
  BrowseInfo : TBrowseInfo;
  DisplayName : array[0..MAX_PATH] of char;
  TempPath : array[0..MAX_PATH] of char;
begin
  FillChar(BrowseInfo, sizeof(TBrowseInfo), #0);
  BrowseInfo.hwndOwner := Form1.Handle;
  BrowseInfo.pszDisplayName := @DisplayName;
  TitleName := 'Please specify a directory';
  BrowseInfo.lpszTitle := PChar(TitleName);
  BrowseInfo.ulFlags := BIF_RETURNONLYFSDIRS;
  lpItemID := SHBrowseForFolder(BrowseInfo);
  if lpItemId <> nil then begin
    SHGetPathFromIDList(lpItemID, TempPath);
