How to silently start process using Poco/Process or other op

[umen]

Hello all
I need to start process and read its stdout output ,without starting the cmd(dos black window)
Can I do that? For example I have this code that opning the cmd window . this is what I like to avoid .

Code: Select all

std::string cmd = "C:\\WINDOWS\\system32\\ipconfig";
std::vector<std::string> args;
args.push_back("--help");
   
Pipe outPipe;
ProcessHandle ph = Process::launch(cmd, args, 0, &outPipe, 0);
PipeInputStream istr(outPipe);
std::string s;
int c = istr.get();
while (c != -1) { s += (char) c; c = istr.get(); }
int rc = ph.wait();

I'm actually in the same situation, I tried searching Google and POCO Documentation but couldn't find an answer
to how running a process silently.

Did you found a solution?

Thanks.

I don't believe that feature is available in Poco Process.

I had to modify the ProcessImpl::launchImpl() function in Foundation/Process_WIN32.cpp to suppress the cmd window from opening.

Code: Select all

STARTUPINFO startupInfo;
   startupInfo.dwFlags     = STARTF_FORCEOFFFEEDBACK | STARTF_USESTDHANDLES | STARTF_USESHOWWINDOW;
   startupInfo.wShowWindow = SW_HIDE;
