Answer 2

RegQueryValueEx(Key,pChar(Value),nil,@ptype,@Data, @Size); //读注册表
RegSetValueEx(Key, pChar(Value), 0, REG_DWORD, @Data, Size); //写注册表

delphi自带的例子:
var
  Reg: TRegistry;
begin
  Reg := TRegistry.Create;
  try
    Reg.RootKey := HKEY_CURRENT_USER;
    if Reg.OpenKey('\Software\Microsoft\Windows\CurrentVersion\RunOnce', True) then
    begin
      Reg.WriteString('MyApp','"' + ParamStr(0) + '"');
      Reg.CloseKey;
    end;
  finally
    Reg.Free;
    inherited;
  end;end;
