Copying file from resource to Program Files

[ihoss]

I'm trying to make a program which will install itself once run. I have everything done except copying a file from the exe's resources path to somewhere on the hard drive. This is the code I use:

QFile file
        QDir::setCurrent(":/resource");
        file.setFileName("lim.jar");
        QDir dir;
        dir.mkdir(pathLineEdit->text());
        if(!file.copy(pathLineEdit->text()+"lim.jar")){
        	pathLineEdit->setText("could not write");
  	  	return;
	}

QFile file
        QDir::setCurrent(":/resource");
        file.setFileName("lim.jar");
        QDir dir;
        dir.mkdir(pathLineEdit->text());
        if(!file.copy(pathLineEdit->text()+"lim.jar")){
        	pathLineEdit->setText("could not write");
  	  	return;
	}

To copy to clipboard, switch view to plain text mode
