In this case, however the directory listings are obtained 17from an FTP server anywhere on the network. Since FtpCat has no browse 18facility, you will have to use CatSend & CatrRecv (or Dump) to examine 19the contents of the resulting catalog. </p> 20 21<p><b>What it illustrates</b>: FtpCat is a 32-bit console application, 22which is dynamically linked to both Metakit and MFC. FtpCat is a bit peculiar, 23in that it uses the FTP.EXE application which is part of Windows 95 to 24take care of all networking (after all, Metakit is not an introduction 25on how to build ftp clients). There are no ftp-related routines, nor even 26any Winsock calls, in FtpCat. There is a fair amount of tricky code in 27here to juggle two pipes which are used to control the child process (ftp.exe). 28</p> 29 30<p><b>How to use it</b>: FtpCat is very simple to use: simply call it with 31an URL as argument, and it will open an ftp connection and retrieve the 32listings of the specified directory and all its subdirectories. If you 33do not supply a second parameter, the catalog will be stored in a file 34called "ftpcat.dat". As with DisCat, you can then use CatSend 35& CatRecv to examine the catalog contents. </p> 36 37<p>If you're connected to Internet, you could try "ftpcat ftp://ftp.winsite.com/pub/pc/win3/programr"; 38(this is one the areas where new distributions of the Metakit library are 39posted). The "ftp://"; prefix is optional, and you may add a "user:password@" 40prefix to the site to login under a specific name. This allows you to produce 41a catalog of protected areas, for example with "ftpcat user:passwd@mysite.org/mydir". 42Please be aware of the fact that some sites on internet are huge, and that 43a command such as "ftpcat ftp.winsite.com" which uses "/" 44as default path may take some time to complete, depending on the speed 45of your connection. </p> 46 47<p><b>Known problems</b>: None, but there are some limitations in this 48sample application: </p> 49 50<ol> 51<li>The "site:port" notation is not implemented, you can only 52connect to standard ftp servers. </li> 53 54<li>This version does not commit intermediate results to file. If you cancel 55it, nothing is saved. </li> 56</ol> 57 58<p><b>Files in EXAMPLES\FTPCAT</b>: </p> 59 60<p>FTPCAT.CPP - FtpCat main program 61<br>FTPCAT.MAK, FTPCAT.MDP - MSVC 4.2 project makefiles for Win32 </p> 62<!--end--> 63 64<center><p><hr size=1> 65|| 66 <a href="index.html" target="_top">Roadmap</a> 67 <a href="classes.html">Class Index</a> 68 <a href="samples.html">Sample Index</a> 69 || 70 <a href="intro.html">Introduction</a> 71 <a href="tips.html">Tips and Tricks</a> 72 || 73 74</center> 75</font> 76 77</body></html> 78
