Qt：QProcess实现cmd命令，带参数.exe程序

首先引入都文件 #include <QProcess>

1、执行cmd命令

QProcess program;
QString cmd = "xxxxxx"; //选择自己要执行语句
program.start(cmd);
program.waitForFinished();

2、启动外部exe程序

QProcess program;
QString cmd = "xxx.exe"; //选择自己要执行exe程序
program.start(cmd);
program.waitForFinished();

3、启动一个带参数的exe程序

QProcess program;
QString cmd = "xxx.exe";
QStringList args;
args.append("-h");
program.start(cmd, args);
program.waitForFinished();
