I try to launch internet explorer, So I use the below code
QProcess * process=new QProcess(this);
QString temp="C:\\Program Files\\Internet\ Explorer\\iexplore.exe";
process->startDetached(temp.toStdString().c_str());
But it doesn't work.
Try:
QProcess * process=new QProcess(this);
QString temp="\"C:\\Program Files\\Internet Explorer\\iexplore.exe\"";
process->startDetached(temp);
You need to use escaped quotes since the path has a space in it, or possibly escape all the spaces (you missed Program\ Files
in the code you posted).
