Примерно вот так

function BrowseFolder(Parent:hWnd=0): string; var lpItemID : PItemIDList; BrowseInfo : TBrowseInfo; DisplayName,TempPath : array[0..MAX_PATH-1] of char; begin FillChar(BrowseInfo, sizeof(TBrowseInfo),#0); BrowseInfo.hwndOwner:=Parent; BrowseInfo.pszDisplayName:=DisplayName; BrowseInfo.lpszTitle:="

Всем спасибо!
