Currently I am creating a new file after every 100th entry, which works =
GREAT.=20

I have searched online for some help, but unable to. Is there any syntax =
or algorithms for creating a new file, giving a specific time or date.=20

Are you asking how to code this or is there a c++ function that will do=20
this?  I don't know of one in c++, but the posibilities of doing this wit=
h=20
your program are endless (of course, depending on what you really want to=
=20
do.)  I will suggest, however, to look at the at command for both unix (m=
an=20
at) and windows (help at).  It will let the OS do that job for you instea=
d=20
of you having to figure out the whole time/date problem. Plus, your progr=
am=20
won't be running all the time, but instead, it will be run at the specifi=
c=20
time that you want. ie,

Windows:

at next: tuesday createfile.exe

Unix:

at -q s -m -f bin/sendgaz 5:30 Tomorrow

by the way, in Unix, there are different flavor of at/cron or other=20
utilities that could do this for you.

I hope this helps.

Schedule a task which calls the executable that generates the data file at a given date and time.  cron in Unix/Linux, Task Scheduler in Windows xx.

Re: [Dev-C++] new file creation

[Gerson L. <ja...@ya...>]

Hello all!.
 
I must first apologize for not beeing specific, its not my style but...
there are just some general ideas:
 
#include <time.h> // for C programs
#include <ctime> // for C++ programs
 
Im not shure how to use this library, but the function time returns a value representing the actual time of the system, i think it is an integer counting the miliseconds transcurred since some important date. the idea is to check the diference between two "timestamps". I've done such thing but for interval of minutes...
 
Also, there is a Timer event that may be useful, but it requieres windows programing, I mean WinAPI functions, since the timer messages are given to a window as otrar messages... like pressing a button in the mouse sends a message to the corresponding window. this may be a lot of hard work for a little task...
 
If your program runs on a computer that is being turned on and of constanlty or between the interval you need to create the files, (in windows) i sugest to have a very little "dot exe" placed in Start Menu/Programs/startup, or a shortcut. The program should only check the date/time an determine wich tasks must be done, and if any, call the main program. Make this as small as possible in order to not make the system startup any longer.
Another way of doing this is to set a value n the registry, usually in HKLM/software/microsoft/windows/current version/run, the value of type string must be tha complete path of the program to run.( i have done this manually, no idea how o white to the registry via code) 
(Win98 and WinXP, others, I DONT KNOW)
 I supose Linux has something similar.
 
If you are shure the program will be running by the time the file is to be created, the only thing you need is to be constantly cheking the date/time.
 
my apologies again, too much words, i know. If anyone can iluminate me about what i mentioned, I WILL apeciate it.
 
I once did something like our firend here needs, but I used Visual Basic.
(it was not voluntary!!!) so...
