以前一直没找到CFtpConnection的简单封装类，所以今天自己写了一个，供有需要的朋友使用
该类只是简单的封装，不可能达到socket来实现FTP功能的灵活和性能。
你也可以自己改造，如类里加入线程启动下载，加入上传下载通知消息等，因为我用不上，所以就不加了
使用HTTP上传下载的方法也类似，可以做为参考
使用说明：
CMyFtp ftpTest("192.168.16.63", "test", "test112", 21);
bool result = ftpTest.UploadFile("336.txt","d://111.txt");
if(!result)
AfxMessageBox(ftpTest.GetErrorMsg());
ftpTest.DownloadFile( "336.txt", "12.txt");
ftpTest.CreateRemoteDirectory("test222");
ftpTest.SetRemoteDir("test222");
ftpTest.UploadFile("113.txt","d://111.txt");
ftpTest.SetRemoteDir("//");
ftpTest.UploadFile("116.txt","d://111.txt");
