running a cmd command using Qt

[d_stranz]

How many times does this same question have to be answered in this forum?

If you want to run a command with command line parameters using QProcess, you have to give QProcess::start() or QProcess::startDetached() at least two arguments: a QString containing the command to be executed and a QStringList containing the parameters to the command:

QString  command( "cmd.exe" );
QStringList params = QStringList() << "/k" << "ping" << "1.1.1.1" << "-n" << ... and so forth
 
QProcess::startDetached( command, params );

QString  command( "cmd.exe" );
QStringList params = QStringList() << "/k" << "ping" << "1.1.1.1" << "-n" << ... and so forth

QProcess::startDetached( command, params );

To copy to clipboard, switch view to plain text mode 

QProcess::startDetached() is a static method, therefore no QProcess instance is required.

Hi. I took your code above and used in my program but the actual CMD window does not get displayed... I can see in task manager that it was started. How do you get it to display? Apologies for such a noob question, this is my first week into this program... Which is awesome!
