Output from command prompt

[Guest_imported]

How might one go about redirecting the output from a program running in the dos prompt to the exec'ing program...

eg exec(program...) and VIEW the output in a kind of custom dos prompt... is this possible? it must be, everything else is

Off the top of my head, you could redirect the output to a file. Then have the executing program read the file. Maybe something like

exec(program > output.txt);
ifstream InFile;
InFile.open(output.txt);
if (InFile)
{
    string Line;
    while (getline(InFile, Line))
    {
        cout << Line;
    }
}

This is off the top of my head so take that for what it's worth. There are probably easier ways.

No, it cant be through the use of files...

It is possible... If you are going to send to another DOS prompt program you can do it this way! (but I strongly advice that you modify it) just something I mixed up a second ago!


int main(int argc, char* argv[])
{
cout << &quot;Value received from another program is: '&quot; << endl;
for(int i=1 ; i<argc ; i++)
cout << &quot;(&quot; << argv << &quot&quot;;
execv(&quot;project2.exe&quot;, argv);
return 0;
}

int execv(char *path, char *argv[]); Martin G Broman
