I realize that this is not a true database question, but most of my work
is in database and I tend not to follow the other Delphi Groups.

Altho there must be a simple way to typecast an integer to a set and
visa versa, I can't seem to get it.  Read the docs, etc.  Have not had
this prob with other languages.  I can think of inelegant ways to do it,
but I much prefer simple elegance.

Any suggestions?

Thx,

Joe

Hi Joe,

I have tried it and it should work:

procedure TForm2.HCButton1Click(Sender: TObject);
TYPE TXX = (A, B, C, D, E, F, G, H, I, J, K);
    TSetOfXX = Set Of TXX;
VAR
    AnySet : TSetOfXX;
    wSet : Word;
begin
  AnySet := [A, B, C, D, E, F, G, H, I];
  wSet := Word (AnySet);
end;

Hope it helps

Bye

Andreas

Post the exact code that causes problems, so we can help you.
Otherwise, we can only guess...

Close, but only half of the sigar.

A set can contain up to 256 values, so you'll need 32 bytes to hold the
hold shebang (sp?)...

Some experimental code:
{$APPTYPE CONSOLE}
var
  s:set of byte;
  a:array[0..31] of byte;
  i:integer;
begin
  s:=[4, 5, 133];
  for i:=0 to sizeof(s)-1 do
  begin
    a[i]:=byte(pointer(integer(@s)+i)^); //store the set into the array
    write(a[i], ' ');  //bit 4 and 5 is set in the first byte = 48
  end;
  //now the other way, from array to the set:
  s:=[];
  for i:=0 to sizeof(s)-1 do
  begin
    p:=pointer(integer(@s)+i);
    p^:=a[i];
  end;
end.
