Hi all, win2k and delphi 6 here.

    I have a small process that receive a char, i convert it to a hex value, after that i have a convert table which tells me the new hex value. but after i'm stuck at converting back my hex value to a char. any help would be welcome.

just an exemple of where i'm stuck.

function SwapHexValue(mychar : char):char;
var
  ls_string :  string;
begin
  ls_string := inttohex(ord(mychar ),2);
  ls_string := Swap(ls_string);
  result := ???????????//something like result := hextochar(ls_string);
end;

Use StrToInt, with a prefix of '0x' - and it automatically oes hex conversion

i.e.

result := StrToInt( '0x' + ls_string );
