Share with us!

Ok im starting this thread for the beinfit of everyone.

i think alot of us know a subject in terms of programming
very well, and i think that if we would share just one
of these things that we know about a particular subject
that we will all be smarter as a group and help people
better.


so if someone would like to start off on a topic,
you can start by telling us what it is, what its use for,
a example on how to use it, and how it works.

thanks to all who help make this a useful thread.


P.S.
i decided to open this in general thread, even though
it apply's to programming directly, because more then one
language may be covered here, and it may not fall into a
specific group such as networking / win32 / linux / game / etc.
so please post anything to increase are knowledge.
anything useful you have come across.

and please please, dont give someone that post on this thread
to much crap, if they made a mistake, or done something
you dont think to be good practing point it out, with a correct
correction politly, so the thread will move in a positive direction.

well, you could always write and send an article to the webmaster about a topic you feel particularly comfortable with and he will (most likely) post it on the main cprog page for everyone to see, not only the cboard members.

I guess axon's idea sort of messed up the idea of making ths a usefull thread, huh ILoveVectors?

Anyhow, everything starts somewhere...

I thought this might be usefull:

Code:

---

HWND TimeEdit; // Edit box that number is inputted
int num; // Maximum digits in number
char TransStart[num]; // Numer that is inputed in editbox
int Countdown ; // Resualt number transalation
 
GetWindowText(TimeEdit, TransStart, num);
int Do;
for(Countdown = 0, Do = 0; Do < num; Do++){
if(TransStart[Do + 1] == '\0'){
Countdown = Countdown + TransStart[Do] - '\x30';
Do = 100; }
else{
Countdown = Countdown + TransStart[Do] - '\x30';
Countdown = Countdown * 10; } }

---

It converts a number in character format into int number format.

This might be of interest.

Some of us have web sites with tutorials for just this purpose.
