QProcess::start() cannot run a excute file while the QProcess::state() is QProcess::R

Hi there, I got a piece of code right down here:

Code:

---

fullPath = QString("E:/bin/fis/wave.exe"));
QProcess *process = new QProcess();
process->start(fullPath);
if(!process->waitForStarted())
{
   qDebug() << process->state();
}
qDebug() << "~" << process->state();

---

The qDebug() output is:

Code:

---

~ 2

---

It means running (QProcess::Running equals 2) ,but I cannot see any process called wave running on my computer through Task Manager, neither the GUI. Anybody has suggestions?

By the time you are seeing that process would already got into an end.
