How to do a std::system call to launch another console app?

[lucadesogus]

Hello,

normally i use the std::system in this way to launch an executable in another console:

std::system("start app.exe");

but while running tvision application it creates some troubles.
The new console is opened and closed immediately.

Can someone give some hints?

thanks

Hi @lucadesogus!

What application are you trying to run with system? Note that console applications sometimes just print a message and exit immediately. Make sure that this isn't your case.

it's not the case.
Seems that calling the suspend() before the std::system and resume() after allows the new console to stay open.

TApplication::suspend();
std::system("start  app.exe");
TApplication::resume();

That's indeed the only method that always works.

Although I forgot to answer earlier, I did try to reproduce the issue you were facing initially and observed that conhost.exe was crashing. Therefore, this misbehaviour of the console looks like a Windows bug and not something that Turbo Vision can silently work around.
