Get output of CMD line program from C++ (specifically netstat)

Question

I want to be able to run "netstat -n" and grab the output somehow so I can then write it out to another file.

How can I do this in C++ on Windows CE

Thankyou

Chris

But not pretty sure it'll work under CE

You must call CreateProcess and override the process's output handle:

STARTUPINFO aInfo;
...
aINfo.hStdOutput = myHandle;
CreateProcess(..., &aInfo, ...);

I solved this by essentially calling netstat from the cmd prompt, piping the output to a file, and then using it from there. I believe Kerido's answer to be right but this is how I got it working.

This code then launches cmd.exe and telling it to run netstat -n. Note that the /c is required else cmd.exe will not launch the code

int retVal = CreateProcessW(L"cmd.exe", L"/c netstat -n > \"/netstatoutput.txt\"", NULL, NULL, NULL, CREATE_NEW_CONSOLE, NULL, NULL, NULL, NULL);
