调用外部程序

调用外部程序，并且控制窗口是否显示

bool StartProgram(QString filePath, bool bVisiable, bool bWaitting)
{
#ifdef _MSC_VER
    STARTUPINFOW si;
    PROCESS_INFORMATION pi;
    ZeroMemory( &si, sizeof(si) );
    si.cb = sizeof( si );
    si.dwFlags = STARTF_USESHOWWINDOW;

    //bVisiable控制窗口是否显示
    if (bVisiable)
    {
        si.wShowWindow = SW_SHOW;
    }
    else
    {
        si.wShowWindow = SW_HIDE;
    }
    ZeroMemory( &pi, sizeof(pi) );

    if( !CreateProcessW( NULL, (LPWSTR)filePath.utf16(), NULL, NULL, FALSE, 0,
        NULL, NULL, &si, &pi ) )
    {
        return false;
    }
    //bWaiting = true, 等待程序执行完成
    if (bWaitting)
    {
        WaitForSingleObject( pi.hProcess, INFINITE );
        CloseHandle( pi.hThread );
    }
#endif
    return true;
}
