主要用QProcess类解决这个问题
如执行a.exe, 带两个参数为 -z20，-q85
第一种方法：使用QProcess类静态函数
QProcess::startDetached(const QString &program, const QStringList &argument)
或者
QProcess::execute(const QString &program, const QStringList &argument)
startDetached 函数不会阻止进程， execute会阻止，即等到这个外部程序运行结束才继续执行本进程。
QStringList list;
list<<“-q85″<<“-q85″;
QProcess::startDetached(“a.exe”,list);
list<<“-q85″<<“-q85″;
QProcess::startDetached(“a.exe”,list);
或
QProcess::execute(“a.exe”,list);
第二种方法：创建QProcess类，这种方法的好处是可以查看外部程序返回的数据，输出结果
QProcess *pProces = new QProcess(this);
connect(pProces, SIGNAL(readyRead()),this, SLOT(on_read()));
QStringList list;
pProces->start(“a.exe”, list);
connect(pProces, SIGNAL(readyRead()),this, SLOT(on_read()));
QStringList list;
pProces->start(“a.exe”, list);
slot 函数:
void on_read()
{
QProcess *pProces = (QProcess *)sender();
QString result = pProces->readAll();
QMessageBox::warning(NULL, “”, result);
}
{
QProcess *pProces = (QProcess *)sender();
QString result = pProces->readAll();
QMessageBox::warning(NULL, “”, result);
}

QProcess::startDetached(“ExternalExe/fileAmountMonitor/fileAmountMonitor.exe”,QStringList(),“ExternalExe/fileAmountMonitor”)
