Question

uno

Hello,
I am a beginner with the programming and I have some question. I am
reading manuals from Internet and some book from the library. In all
those documents the C language operate wint plain text files, and I want
to know how operate with formated files (msexcel, msaccess, mysql,
etc..). If it isn't possible with C, with C++ is possible?
Thanks
a beginner
(P.D.- Sorry for my poor english)

Hi uno,

First of all, please use more specific summaries in your subject
line: this is for your own good, as well as to avoid ticking off
the regulars. There are many readers here who skim based on the
subject line, and your subject line doesn't include enough
information to determine whether someone should bother reading
the message or not, so many people will just skip it.

Now, as to your question: pretty much any programming language
which operates on files can deal with files of a specific file
format; however, you need to know how those files are formatted
before you can deal with them. http://www.wotsit.org is
an invaluable archive of a variety of formats; however, MS
proprietary formats tend to be very tricky to handy because MS
typically does not publish their formats. Also, you can
frequently find C libraries which have already done the dirty
work for you, providing a friendly interface to the format.

HTH,
Micah

It's possible with both languages. You need only open the file in binary mode and read away. The hard part may be getting the binary file format
from the creator. Read up on fopen(), fread(), fwrite(), fseek(),
ftell(), and fclose().

Poor advice, IMHO. It's certainly possible, and IIRC it's even been done

by at least one subscriber to this newsgroup, but doing it this way for
Microsoft formats is just asking for pain and suffering.


I'd even say, _never_ do it in production code, but sometimes an ugly hack
may be necessary, just for one run.
<OT> That kind of hack paid me beautiful holydays with my family two years
ago, when a customer had inadvertent deleted a table from a huge Access
database (no backup, of course :), and there is no official way to
"undelete" records in this case, but the information is still there..) </OT>

OK, now I understand it.
