to see such a good post, turned out to be under WinCE FTP implementation , but made in the . NET technologies > C # area, I believe some CE enthusiasts may not be able to see , so go to the CE jar .
Thank zhouzhangkui source out !

------ Solution - -------------------------------------------
http:// blog.csdn.net/oushengfen/article/details/8863009
me a while ago , they shared out , the landlord is the above code in WINCE not normally use . I was in WINCE used .
------ Solution ------------------------------------ --------
Although not used, but the code was pretty good !
------ Solution ---------------------------------------- ----
before the time around , I also suffer from no such DEMO, the efforts of the parties to achieve . Then share it .
hope more people share more and better things for everyone to learn and progress together . . .
