随机生成汉字！

var
  aa: string;
  bb: array[1..95] of byte;
  cc: array[1..95] of byte;
  i, j: integer;
begin
  i := $A0;
  for j := 1 to 95 do
  begin
    bb[j] := i;
    cc[j] := i;
    inc(i);
  end;
  Randomize;
  for i := 1 to 3 do
  begin
    aa := aa + chr(bb[Random(95)]) + chr(cc[Random(95)]);
  end;
  Self.my1.Lines.Add(aa);
end;

 

function TfrmPWGenerate.btnGenerateClick(Sender: TObject): string;

{max length of generated password} 
const 
   intMAX_PW_LEN = 10; 
var 
   i: Byte; 
   s: string; 
begin 
   {if you want to use the "A..Z" characters} 
   if cbAZ.Checked then 
     s := "ABCDEFGHIJKLMNOPQRSTUVWXYZ" 
   else 
     s := "";

   {if you want to use the "a..z" characters} 
   if cbAZSmall.Checked then 
     s := s + "abcdefghijklmnopqrstuvwxyz";

   {if you want to use the "0..9" characters} 
   if cb09.Checked then 
     s := s + "0123456789"; 
   if s = "" then exit;

   Result := ""; 
   for i := 0 to intMAX_PW_LEN-1 do 
     Result := Result + s[Random(Length(s)-1)+1]; 
end;

initialization 
   Randomize;

   function    GetRandomString:string;   
   var   
       len,I:byte;

   begin

       For    I:=1    to    len    do
