Netfolk: I would like to read the current directory in a C program, but either the books I have been reading (the Turbo C reference and my library of beginner's books on the language) don't mention it, or I don't know where in the index to look. I assume there's some call that returns an array of pointers to strings, but I really can't figure it out. Help much appreciated. Post or E-mail, as you wish. 73, David

Turbo C should include a findfirst() and findnext() functions, which allow you to pass both a file "specification" and attributes. It's usually done something like this (node that the given path can include wildcards): . . #include <dos.h> #include <dir.h> . . . { int j; struct ffblk ff; /* contains directory data */ j = findfirst ("*.*", &ff, FA_RDONLY|FA_HIDDEN|FA_SYSTEM|FA_DIREC); while (j) { /* store information or do whatever */ j = findfirst (&ff); } . . david -- uucp: ...!munnari!csource!david internet: david@csource.oz.au Via FidoNet 3:632/348, Melbourne, Australia.

It has two functions you may be interested in (not sure what your application is): wpickstr and wpickfile. These functions put up a user-defined window complete with highlight bar and user-defined/or-not movement that lets the user pick a string from an array *OR* pick a filename from the disk structure (user can follow tree up or down). It comes in Microsoft, Zortech (?) and Borland flavors. Lots of docs, too.

In Turbo-C, there is are 2 functions, findfirst and findnext, which will give you what you need. They should both be in your Turbo-C reference guide. If you are not using turbo-c, similar MS-DOS system calls can be made. If you can't find the information in your reference guide, let me know, and I will give you the proper syntax for either the C commands, or system calls. Sofus Macskassy

David:
On my system (713-350-6284) I have three very small and simple files
that demonstrate the migration from C to single inheritance C++. The section
of the program that obtains the directory is standard C. The FileNames are
DL_1.ZIP, DL_2.ZIP, and DL_3.ZIP with the first being the closest to standard
C. Note, these programs were designed to help beginners.
C++ing a little better,
Roy Browning
