我正在尝试通过Wifi将Surplex VR跟踪鞋连接到我的台式电脑，但不幸的是，微软在其无穷的智慧中已经弃用了设置简单Wifi热点功能的功能。
他们提供了一些示例C++代码，允许创建一个“传统”热点，但它有一个主要缺陷，使其无法使用 - 每次运行时都会生成一个随机密码。
我是一个从未碰过C++的Python初学者，但我想硬编码当前随机生成的内容似乎是很简单的，但似乎C++有多种不同类型的字符串，方法对于它们得到的内容挑剔？
这是处理SSID和密码的当前代码块：
// 要么指定一个密码，要么读取随机生成的一个
ComPtr<IPasswordCredential> passwordCredential;
hr = _legacySettings->get_Passphrase(passwordCredential.GetAddressOf());
if (FAILED(hr))
{
    throw WlanHostedNetworkException("Get Passphrase for WiFiDirectLegacySettings failed", hr);
}
if (_passphraseProvided)
{
    hr = hstrPassphrase.Set(_passphrase.c_str());
    if (FAILED(hr))
    {
        throw WlanHostedNetworkException("Failed to create HSTRING representation for Passphrase", hr);
    }
    hr = passwordCredential->put_Password(hstrPassphrase.Get());
    if (FAILED(hr))
    {
        throw WlanHostedNetworkException("Set Passphrase for WiFiDirectLegacySettings failed", hr);
    }
}
else
{
    hr = passwordCredential->get_Password(hstrPassphrase.GetAddressOf());
    if (FAILED(hr))
    {
        throw WlanHostedNetworkException("Get Passphrase for WiFiDirectLegacySettings failed", hr);
    }
    _passphrase = hstrPassphrase.GetRawBuffer(nullptr);
}

HString hstrSSID = HString::Make(L"surplex-io");
HString hstrPassphrase = HString::Make(L"abcd1234");
_ssid = hstrSSID.GetRawBuffer(nullptr);
_passphrase = hstrPassphrase.GetRawBuffer(nullptr);

I am trying to connect my Surplex VR tracking shoes to my desktop via Wifi but unfortunately Microsoft in their infinite wisdom have depreciated the functionality to setup a simple Wifi hotspot.
The have provided some example C++ code that allows the creation of a &quot;legacy&quot; hotspot but it has one major flaw that makes it impractical to use - it generates a random password every time it is ran.
I am a Python novice that has never touched C++ before but I figured hard-coding something that is currently randomly generated would be straightforward but it seems like C++ has multiple different kinds of strings and methods are picky about what they are given?
This is the current block of code that handles the SSID and passcode:

// Either specify a passphrase, or read the randomly generated one
ComPtr<IPasswordCredential> passwordCredential;
hr = _legacySettings->get_Passphrase(passwordCredential.GetAddressOf());
if (FAILED(hr))
{
    throw WlanHostedNetworkException("Get Passphrase for WiFiDirectLegacySettings failed", hr);
}
if (_passphraseProvided)
{
    hr = hstrPassphrase.Set(_passphrase.c_str());
    if (FAILED(hr))
    {
        throw WlanHostedNetworkException("Failed to create HSTRING representation for Passphrase", hr);
    }
    hr = passwordCredential->put_Password(hstrPassphrase.Get());
    if (FAILED(hr))
    {
        throw WlanHostedNetworkException("Set Passphrase for WiFiDirectLegacySettings failed", hr);
    }
}
else
{
    hr = passwordCredential->get_Password(hstrPassphrase.GetAddressOf());
    if (FAILED(hr))
    {
        throw WlanHostedNetworkException("Get Passphrase for WiFiDirectLegacySettings failed", hr);
    }
    _passphrase = hstrPassphrase.GetRawBuffer(nullptr);
}

And this is what I thought I would need to replace it with to make it functional

HString hstrSSID = HString::Make(L"surplex-io");
HString hstrPassphrase = HString::Make(L"abcd1234");
_ssid = hstrSSID.GetRawBuffer(nullptr);
_passphrase = hstrPassphrase.GetRawBuffer(nullptr);

It was suggested I could use the Make method to turn a regular old string into the HString required by the rest of the code.
However I am repeatedly told
> 'Make': is not a member of 'Microsoft::WRL::Wrappers::HString'
Some investigation suggested the Make method of HString could be found in the icrosoft.WRL.Wrappers.h header file which is included in the Windows 10 SDK and I'd need to include that. But the Windows SDK does not include a file of this name so I'm at a bit of a loss.
The original unmodified demo code can be found here:
https://github.com/zig13/WiFiDirectLegacySurplex
I hope to hardcode the SSID and passcode to the defaults used by Surplex* shoes and make it available on Github for others in the same position. *Although I will probably set a different password for my own use

只移除对提供密码短语的条件检查，并始终使用该分支来设置密码，`.c_str()` 可以替换为字符串字面量 `L"password"`。
```cpp
ComPtr<IPasswordCredential> passwordCredential;
hr = _legacySettings->get_Passphrase(passwordCredential.GetAddressOf());
if (FAILED(hr))
{
    throw WlanHostedNetworkException("获取 WiFiDirectLegacySettings 的密码短语失败", hr);
}
hr = hstrPassphrase.Set(L"硬编码密码");
if (FAILED(hr))
{
    throw WlanHostedNetworkException("创建密码短语的 HSTRING 表示失败", hr);
}
hr = passwordCredential->put_Password(hstrPassphrase.Get());
if (FAILED(hr))
{
    throw WlanHostedNetworkException("设置 WiFiDirectLegacySettings 的密码短语失败", hr);
}
