QProcess

Hi all !

I'm trying to launch a program (any... if only one function that will be nice :p)

Code:

---

QProcess myprocess;
myprocess.startDetached("cmd.exe");
myprocess.waitForStarted(100000);
QMessageBox::information(0,"","");

---

With this code I have directly the message box but I never saw the cmd.exe prompt (win xp)... what's going wrong please :( (I'm looking for hours...)

Thanks !

edit:

I also tried this :

Code:

---

QString sbrowser = "C:\\Program Files\\Internet Explorer\\IEXPLORE.EXE";
QStringList qsl;
QProcess pbrowser;
qsl.push_back("http://www.google.com");
int tmp = pbrowser.startDetached(sbrowser, qsl);

---

(of course it didn't work...)

QProcess::startDetached() is a static method --- you invoke it without an object instance:

Code:

---

QProcess::startDetached( "iexplore.exe", QStringList() << "http://www.google.com" );

---

True but that doesn't changed a lot of things but now I found this :

QProcess::FailedToStart == pbrowser.error()

with pbrowser.start(sbrowser, qsl); (instead of startDetached)

Try:

Code:

---

QProcess::startDetached( "C:/Program Files/Internet Explorer/iexplore.exe", QStringList() << "http://www.google.com" );

---

valid instruction ! but don't work too :'(... that IS the problem...

of course, the file exists (QFile::exists return true) ;)

I tried this too :

Code:

---

QString sbrowser = "C:\\Program Files\\Internet Explorer\\IEXPLORE.EXE";
    QProcess *pbrowser = new QProcess();
    QStringList qsl;
    qsl.push_back("http://www.google.com");
    pbrowser->start(sbrowser, qsl);
    if(QProcess::FailedToStart == pbrowser->error()) QMessageBox::information(0,"", "1");
    else if(QProcess::Crashed == pbrowser->error()) QMessageBox::information(0,"", "2");
    else if(QProcess::Timedout == pbrowser->error()) QMessageBox::information(0,"", "3");
    else if(QProcess::WriteError == pbrowser->error()) QMessageBox::information(0,"", "4");
    else if(QProcess::ReadError == pbrowser->error()) QMessageBox::information(0,"", "5");
    else if(QProcess::UnknownError == pbrowser->error()) QMessageBox::information(0,"", "6");
    QProcess::startDetached(sbrowser, qsl);

---

nothing at all (the message box shows 1 and the doc says:

Quote:

---

The process failed to start. Either the invoked program is missing, or you may have insufficient permissions to invoke the program.

---

it exists ... and I'm with the admin account (the only account in my computer)

Does this work on your system?

Code:

---

#include <QCoreApplication>
#include <QProcess>
 
int main( int argc, char **argv )
{
   QCoreApplication app( argc, argv );
   QProcess::startDetached( "C:/Program Files/Internet Explorer/iexplore.exe", QStringList() << "http://www.google.com" );
   return 0;
}

No and I just figured it out : KERIO (firewall) :eek:

Is there equivalent functions that aren't blocked by firewalls and antivirus ??

resolved : I cleared all my settings in kerio...

Won't such functions render them useless?

No, because only GoodPeopleTM can use them.
