running system commands??

is there a way i can do a system command (if thats wut u call it) in c++ something lke
cout << "net send * messsage";
and if so how would i do it without having to display it in the dos windows with the cout?

It's in the FAQ. Option 1, i.e. the system command would likely do what you want.

Here's what I did. Take a look.

Code:

// MeGaBite1's Net Send App v0.1
#include <iostream>
#include <sstream>
#include <string.h>
using namespace std;

int main(void)
{
    int nummsg;
    int n = 0;
    std::stringstream stream;
    char ipaddr[20];
    char msg[200];
	
    cout << "MeGaBiTe1's Net Send App v0.1\n";
    cout << "Enter Computer Name or IP:\n ";
    cin >> ipaddr;
    cout << "Enter Message:\n ";
    cin.getline (msg,200);
    cin.getline (msg,200);
    cout << "Enter Number of Messages to be Sent:\n ";
    cin >> nummsg;
	
    stream << "net send " << ipaddr << ' ' << msg; 
    
    system ("PAUSE");
   
    while (n < nummsg) {
        std::system(stream.str().c_str());
        n++;
    } 
    
    system ("PAUSE");
    
return 0;
}

so which command is the system one cause you jst gave me a program and i cant exactly tell

It's the one that says, "system". Do you know C++?

the answer is pretty obvious

so which answer is the obvious one cause you jst gave me a sentence and i cant exactly tell

i belive the should be clue enough

Umm.... I'll google it....

im not very good at c++ yet and how am i supposed to know that answer thats y i asked (sean), i didn't ask for a whole program either (even though it was small)

Code:

    stream << "net send " << ipaddr << ' ' << msg; 
    
    system ("PAUSE");
   
    while (n < nummsg) {
        std::system(stream.str().c_str());
        n++;
    } 
    
    system ("PAUSE");

if its the system command why is there a stream next to the commands then a
system ("PAUSE") thing, i assume its stream but i have no idea wut the system ("{AUSE") is?

A forum is not a good medium for teaching the basics of object oriented programming. To send a command to the system, place the command in a C-style string and place either the string literal or a pointer to the first element of the array in parenthese next to the word system, and be sure to include cstdlib.

i dont really get wut you mean, could you just answer my question cause i still dont know the syntax of it or wut some of the other stuff in the net send program was

can anyone help me???

>can anyone help me???
From what I can tell, you're beyond help. system is a function, you give it a C-style string containing the system command you want processed as an argument. For example, if I wanted to use the DOS pause command I would do this:

Code:

#include <cstdlib>

...

std::system ( "pause" );

If I wanted to do a tracert for cprogramming.com I would do this:

Code:

std::system ( "tracert www.cprogramming.com" );

If that's too much for you then you need to go back to the beginning and study functions. Otherwise you'll just end up being frustrated.
