Ftp

代码说明：

  在用PB进行开发时常常需要用到ftp功能，最典型的应用就是将数据窗口中的数据生成txt文件，然后将此数据文件用ftp发送到远程服务器上去。由于pb本身并未提供任何ftp的功能，因此想在pb中进行ftp传输，只能应用pb以外的资源。以下是笔者在pb开发中总结出来的方法。(When developing with PB, FTP function is often used. The most typical application is to generate TXT file from data window, and then send it to remote server with ftp. Because the Pb itself does not provide any FTP functions, if you want to transfer FTP in pb, you can only use resources other than pb. The following is the method summarized by the author in the development of pb.)
