MFC逐行提取数据并显示到不同对话框中？？？
$PMTKANT,1*44
$GPGGA,010709.000,2425.6396,N,10922.7710,E,2,9,0.85,116.1,M,-18.2,M,0000,0000*77
$GPGSA,A,3,14,29,31,32,22,30,16,25,20,,,,1.79,0.85,1.57*0F
$GPGSV,3,1,11,30,60,218,49,31,52,350,49,14,51,081,43,50,41,119,37*74
$GPGSV,3,2,11,32,36,307,47,22,32,173,47,16,30,209,50,25,25,039,46*7E
$GPGSV,3,3,11,29,17,081,39,20,10,317,41,06,03,187,37*4B
$GPRMC,010709.000,A,2425.6396,N,10922.7710,E,16.81,16.80,200712,2.3,W,D*19

很多组这样的数据，我想每隔一秒读取一组数据（上面所有6行为一组），并将$GPRMC这一句的010709.000和A显示到不同的对话框中，该怎莫实现啊？？
我新手一个，求大哥写点注释，小弟在这先谢您啦。

[解决办法]
CStdioFile逐行打开数据
再SSscanf选择数据
