Hi
  I'm writting a programm in Delphi 5.
I want to get windows directory ,so i use GetWindowsDirectory API.
When I run it in Delphi there is no problem ,but
When i run it alone it doesn't give me the directory.
What's the matter?

You probably did not allocate memory for the buffer.
This should work:

function GetWinDir: String;
var a: array[0..MAX_PATH] of Char;
begin
  GetWindowsDirectory(a, sizeof(a));
  Result := a;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  ShowMessage(GetWinDir);
end;
