QProcess

[agent007se]

Hi all !

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

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

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

To copy to clipboard, switch view to plain text mode 

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 :

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);

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);

To copy to clipboard, switch view to plain text mode 

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

myprocess.startDetached("cmd.exe");

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

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

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)

[jacek]

Try:

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

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 :

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);

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:

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?

#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;
}

#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)

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.

Lol. Very funny . I just cleared my settings so it was my fault and now it works pretty well .
