Network usernames ...

Hi!

I want to make a program to talk to people in a network, so i'll be using the system net send command ... I've a couple of questions though:

does anyone know if there is a way I can actually check to see if people are online or not?? there are computer names of course, but if a user logs onto a computer, you can either send the message to the computer name, or the user name of the person whose on it. (I'm sure you all know this already). I just think it'd be a neat way of making a program, kinda like MSN/Googletalk but on a console :D

also, is there a better way of communication besides using net send?

thanks!

It is best to not use netsend. SP2 shuts it down my default so unless you want people who use your program to have to go through a long process to reenable it, I would suggest learning Winsock or another such api system and writing your own program entirely.

Here is a thread that should answer your question:

Hey,

thanks for that anonytmouse!! I tried searching through the forums beforehand to see if anyone had posted it, but I restricted it solely to the networking board .... either way ....

it's giving me this error:

error C2664: 'lstrcpyA' : cannot convert parameter 2 from 'unsigned char [16]' to 'const char *'

which is referring to this line:

Code:

---

lstrcpyA(szMachine, pNames[i].name);

---

hmmm, any ideas??

I originally compiled it with C. C++ has stricter type checking. In this case, you can just use a cast:

Code:

---

lstrcpyA(szMachine, (LPCSTR) pNames[i].name);
