Execute windows command inside C++ and redirect the output to local string

Question

I'm trying to execute

    which file.exe

within c++ and want to redirect the result to a string to make further processes

I've tried system and CreateProcess but this executes command and redirects the results to stdout or a file.

but how do I get this result within a local string ?

Thanks

Redirect to a pipe (with CreateProcess) and read your end of the pipe into a local string.

I recommend to use _popen (popen on Unix).

Did it start working in GUI-subsystem executables? (It was not)

Are you sure there were problems? I'm not aware of any.

See the Note starting with "If used in a Windows program" on your own link to MSDN. I'm sure there were (or are) some real problems, I just don't remember them well.

Ah, I see. So whether this is good advise or not depends on whether the OP wants to create a GUI or console application.

both were helpful. I use console app so it's easier to use _popen Thanks
