DELPHI中通过SHBrowseForFolder函数实现选择目录

uses ShellAPI, ShlObj;

procedure TForm1.Button1Click(Sender: TObject);

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);

ShowMessage(TempPath);

GlobalFreePtr(lpItemID);

end;

end;
