qt - QProcess not work with start but work with startDetached -

i have problem start dos application qprocess::start.

#include <qtgui/qapplication> #include <qprocess>  int main(int argc, char *argv[]) {     qapplication a(argc, argv);      qprocess *process = new qprocess();     process->start("c:\\femag\\wfemag_02-2013.exe");      return a.exec(); } 

the executed application fails @ point kind of error "invalid handle".

when use

process->startdetached("c:\\femag\\wfemag_02-2013.exe"); 

the application starts ok. need use process->start().
