QProcess 启动win第三方程序

我不知道哪里错了

    prog = new QProcess(this);

    QString fullpath = QString("%1/%2").arg(QCoreApplication::applicationDirPath()).arg(exeName);

    qDebug() << "launch full path =" << fullpath << ", argv =" << argv;

    prog->setObjectName(fullpath);

    connect(prog, SIGNAL(finished(int,QProcess::ExitStatus)),

            this, SLOT(finishedSlot(int,QProcess::ExitStatus)));

    prog->start(fullpath, argv);

如果这样写就启动不起来。

下面写的就可以

    m_pOtherProcess = new QProcess(this);    QString t_otherExePath = QString("%1/%2").arg(QCoreApplication::applicationDirPath()).arg(otherExeName);    QString t_otherExeDirPath = QString("%1").arg(QCoreApplication::applicationDirPath());    if(!QFile::exists(t_otherExePath))    {        qDebug()<<"robin:otherExe not exist";        return -1;    }    connect(m_pOtherProcess, SIGNAL(finished(int,QProcess::ExitStatus)),            this, SLOT(finishedSlot(int,QProcess::ExitStatus)));    m_pOtherProcess->setObjectName(t_otherExePath);    m_pOtherProcess->setWorkingDirectory(t_otherExeDirPath);    m_pOtherProcess->setProgram(t_otherExePath);    m_pOtherProcess->start();

我不想找原因了，我要忙别的了。其实上面的代码之前也是可以的，但是不知道为什么不行了

下面是终极办法，肯定可以。

bool runWinExe(const QString &path)

{

Q_ASSERT(QFile::exists(path));

bool run = false;

#if defined(Q_OS_WIN)

SHELLEXECUTEINFO sei = { sizeof(SHELLEXECUTEINFO) };

sei.lpVerb = TEXT("runas");

WCHAR wfile[256];

memset(wfile, 0, sizeof(wfile));

path.toWCharArray(wfile);

sei.lpFile = wfile;//add  application  which you want to run as administrator here

sei.nShow = SW_SHOWNORMAL;//without this,the windows will be hiden

run = ShellExecuteEx(&sei);

#else

run = QProcess::startDetached(path);

#endif

return run;

}
