How to run a console program "silently"?

[fullmetalcoder]

Nop!

I start them through a QProcess object, and not QProcess::startDetached(), itself owned by a running non-GUI QThread.

I've created a small test:

#include <QApplication>
#include <QProcess>
#include <QMessageBox>
#include <QString>
 
int main( int argc, char **argv )
{
   QApplication app( argc, argv );
 
   QProcess proc;
   proc.start("g++ --version");
   proc.waitForFinished();
 
   QString output( proc.readAllStandardOutput() );
 
   QMessageBox::information( 0, "test", output );
 
   return 0;
}

#include <QApplication>
#include <QProcess>
#include <QMessageBox>
#include <QString>

int main( int argc, char **argv )
{
   QApplication app( argc, argv );

   QProcess proc;
   proc.start("g++ --version");
   proc.waitForFinished();

   QString output( proc.readAllStandardOutput() );

   QMessageBox::information( 0, "test", output );

   return 0;
}

To copy to clipboard, switch view to plain text mode 

and it doesn't open console window. Maybe this is because you start QProcess in another thread?

This does not work...

Mmmh, yes it does work but the console windows still appears... It must be specific to Win 9x/ME ...

It must be specific to Win 9x/ME ...

It could be, I've tested above program on windows XP.

win9x/ME ??? I thought they died quite a while ago....

[fullmetalcoder]

do you? You were wrong then... There at least on winME still running on that good old Earth!

But is that the point anyway?

"Good old earth"? Isn't WinME famous of it's memory leaks and stuff. I thought it's maybe the worst Windows ever..

[fullmetalcoder]

It certainly is a great piece of Window$-coding with all the bugs and leaks it implies... AFAI Used it it crashes 1 time over 3 at run-time!!! Impressive, huh? Tha's why I'm using Fedora most of the time, but as it is the only Window$ I've got I use it to test my code so...
