Conversion Delphi / VB

Hello.

Can anyone help me with the Dephi function below...

const  CC_TIME = $3f;

procedure TvStripForm.AddTime(var sum: array of Byte; b: array of Byte);
var
  i: Integer;
  max_f: Integer;
begin
  for i := Low(sum) to High(sum) do
    Inc(sum[i], (b[i] and CC_TIME));
  max_f := 25;
  if ((b[3] and (not CC_TIME_)) = 192) then
    max_f := 30;

  if (sum[3] >= max_f) then begin
    Dec(sum[3], max_f);
    Inc(sum[2]);
  end;
  if (sum[2] >= 60) then begin // seconds
    Dec(sum[2], 60);
    Inc(sum[1]);
  end;
  if (sum[1] >= 60) then begin // minutes
    Dec(sum[1], 60);
    Inc(sum[0]);
  end;
end;


I wan't to create the same function in Visual Basic, but Im struggling, as
I 
don't really know Delphi all that well.  We dont intend to leave Delphi 
behind, someone in our department wants to see if VB tackles the above 
function, as he thinks it will be a much long winded away around.. 
personally I dont think it will.

Any help appreciated
