如何在Qt中访问cmd返回的消息

Question

我正在制作一个在Windows上在Qt Creator中添加新用户帐户的应用程序。应用程序要求输入用户名和密码，然后打开cmd并输入命令net user username password / all。我希望能够创建一个总是等于cmd在输入命令后返回的标签，例如“此帐户已存在”。我的代码如下。

#include <QDebug>  
#include "mainwindow.h"  
#include "ui_mainwindow.h"  
#include "QProcess"  
#include "QTextStream"  
#include <iostream>  

MainWindow::MainWindow(QWidget *parent) :  
    QMainWindow(parent),  
    ui(new Ui::MainWindow)  
{
    ui->setupUi(this);
}

MainWindow::~MainWindow()
{
    delete ui;
}

void MainWindow::on_pushButton_clicked()  
{  
   QProcess process1;  
   QStringList arguments1;  

   arguments1 << "net user" << ui->lineEdit->text() << ui->lineEdit_2->text() << "/add";  
   QString path = "C:/Windows/system32/WindowsPowerShell/v1.0/powershell.exe";

   process1.execute(path, arguments1);  

   QString output(process1.readAllStandardOutput());  

   ui->label_4->setText(output);  
}

Answer 1

process1.QProcess::waitForFinished(-1);
QString output(process1.readAllStandardOutput());
ui->label_4->setText(output);
