Unit zur Verwendung von SHGetKnownFolderPath

[Fritzew]

Hallo Ringli

Danke für die Unit,

aber eine Anmerkung: Dein Code gibt den Speicher nicht frei.


Ich habe es so geändert:

Delphi-Quellcode:

function GetKnownFolderPath(const rfid: TGUID): string;
var
  OutPath : PWideChar;
begin
  if ShGetKnownFolderPath(rfid, 0, 0, OutPath) {>= 0} = S_OK then
    begin
      Result := OutPath;
//   From MSN
//     ppszPath [out]
//     Type: PWSTR*
//     When this method returns, contains the address of a pointer to a null-terminated Unicode string that specifies the path of the known folder
//     The calling process is responsible for freeing this resource once it is no longer needed by calling CoTaskMemFree.
//      The returned path does not include a trailing backslash. For example, "C:\Users" is returned rather than "C:\Users\".
      CoTaskMemFree(OutPath);
    end
  else
    begin
      Result := '';
    end;
end;

Benötigt auch noch die WinApi.ActiveX im uses.
