Re: [Dev-C++] quick question about sending stuff to windows

[Jason H. <jas...@bt...>]

I don't know much about sending stuff around a lan, although if you can take
advantage of a system command then that would make things easier for you. If
you need to add your variables as a string to the net send command (I assume
there is a command like that available?) then you need to concatenate them
onto the net send command string. I suggest you use C++ strings for getting
the input and putting it all together and then convert it to a C string for
use in the command.
i.e.

#include <string>
#include <cstdlib>
#include <iostream>

int main()
{
    std::string name, command;
    char text[256];
    command = "net send "; // assuming this is a valid command?

    cout << "User name: ";
    cin >> name; // Get's until whitespace
    cout << "Send string: ";
    cin.getline(text, 256); // Get's a line of text including whitespace

    command += name + " " + text; // I'm unsure but this should work.

    system(command.c_str()); // use the C string version of command

    cout << "String sent." << endl; // a better way than "\n"
    // do you need to pause?
}

This is all guess work, I don't know what is a valid way of sending messages
across your lan, but I hope it helps.

Jason.
