Re: system()-crash with phpGtk-win32

Possivible tries are: 1 - try turning off Dr. Watson if you are in win2k. I noticed that it has some bad influence over php.exe 2 - also try using the windows shell command "start" in the beging of the command line of system() call. Hope it helps, tell us what happen. ----- Original Message ----- From: "Sebastian G." <mailseppel@gmx.de> To: <php-gtk-general@lists.php.net> Sent: Friday, March 01, 2002 4:55 PM Subject: [PHP-GTK] system()-crash with phpGtk-win32 > Hi, > > for several days now I'm fighting with the opportunity to start an binary exe-file on a Windows 32 system inside my phpGtk-script. > The script is an Scanning-application which is used to scan and archieve images.

If I'd instead kill the TwainCom.exe-binary, my phpGtk-script will continue to run. If I then run the system()-call a second time, everything works fine.
