通用Windows应用程序尝试将Windows控制台应用程序移植到UWA [英] universal windows apps an attempt to port a windows console app to UWA

问题描述

我在c ++控制台应用程序中编写的代码有问题。



代码在c ++&效果很好。  我想将应用程序移植到通用Windows应用程序。



$
我遇到的问题是我正在尝试使用



$


   m_hCommPort = ::的CreateFile（L" \\\\.\\COM3" ;,

        GENERIC_READ | GENERIC_WRITE，         //访问（读写）

        0，     //             （股）0：不能共享COM端口     &NBSP ;                
 

 &NBSP ;      0，    //            安全 （无）                

         OPEN_EXISTING，                 //创建：open_existing

        FILE_FLAG_OVERLAPPED，             //我们想要重叠操作

        0                                        
//没有COM端口的模板文件...

    ）;;
    if（m_hCommPort == INVALID_HANDLE_VALUE）

    {

        ASSERT（0）;           //我总是在这里结束了...
       返回;

    } b

$ b b用于访问com3上的设备：



设备它是虚拟的，它是一个位于usb末端的设备。



驱动程序是Silicon Labs Dual CP210x USB转UART桥接器。



我已经下载了最新的驱动程序。 我也和Silicon Labs谈过了。 实验室不支持通用Windows应用程序。





i已经建议更改package.appxmanifest以包含



  <功能>

    < Capability Name =" internetClient" />
$
        < DeviceCapability Name =" serialcommunication">

      < Device Id =" any">

        < Function Type =" name：serialPort" />
$
      < / Device>

    < / DeviceCapability>

  < / Capabilities>



和是UWA确实编译 - 它运行 但是不起作用 - 特别是m_hCommPort永远不会被初始化并且总是被困住。



$ b我的查询是：任何人都可以提供一些有关如何在Windows 10 VS 2015下正确调用通信设备以获得通用Windows应用的智慧之词吗？



谢谢你

I have a problem with some code that I have written in c++ console app.

The code is in c++ & works well.   I want to port the app to a universal windows appliction.


The problem I have is that I am trying to use



   m_hCommPort = ::CreateFile(L"\\\\.\\COM3",
        GENERIC_READ | GENERIC_WRITE,        //access ( read and write)
        0,    //              (share) 0:cannot share the COM port                        
        0,    //             security  (None)                
        OPEN_EXISTING,                 // creation : open_existing
        FILE_FLAG_OVERLAPPED,             // we want overlapped operation
        0                                        // no templates file for COM port...
    );
    if (m_hCommPort == INVALID_HANDLE_VALUE)
    {
        ASSERT(0);           // I always ended up here
        return;
    }


to access a device on com3:

The device is virtual in the sence that it is a device sitting at the end of a usb.

The driver is a Silicon Labs Dual CP210x USB to UART bridge.

I have downloaded the latest driver.  I have also spoken to Silicon Labs.  The Lab does not support universal windows application.


i have found a recommendation to change package.appxmanifest to include

  <Capabilities>
    <Capability Name="internetClient" />
        <DeviceCapability Name="serialcommunication">
      <Device Id="any">
        <Function Type="name:serialPort" />
      </Device>
    </DeviceCapability>
  </Capabilities>

and yes the UWA does compile - it runs  but does not work - specifically m_hCommPort is never initialised and is always trapped.

My query is: can anybody provide some words of wisdom on how to correctly call a communications device under windows 10 VS 2015 for a universal windows appliction?

thanks
Bruce
