Question

See more:

i want to run few commands that needs wmic but don't want to use system because of two reasons
1)it open command prompt which i don't want to show to the user
2)it uses .txt file to write result into which is then get later fro this file

but i want to use pipes if possible so that i can get the following things without system()function in c++ and can directly store the result in variables without the need of opening files writing results into it and then get it from these files
1)Ipv4 Address
2)UUid

What I have tried:

	system("ipconfig > ip.txt");
system("wmic csproduct get uuid > Uuid.txt")

Solution 1

You can also directly access WMI from C++ (through COM), see WMI C++ Application Examples - Win32 apps | Microsoft Docs[^].

Solution 2

If you want to capture the output from executing a program, use _popen(). eg

C

#include <iostream>
#include <cstdio>

int main()
{
    FILE *pipe = _popen("ipconfig", "r");
    
    if(pipe == NULL) {
        perror("popen");
        return 1;
    }

    char buffer[256];

    while(fgets(buffer, sizeof buffer, pipe) != NULL) {
        std::cout << buffer;
    }

    _pclose(pipe);

    return 0;
}
