[WRL] IRadioStatics.GetRadiosAsync（）在x86中失败：80040154类未注册 [英] [WRL] IRadioStatics.GetRadiosAsync() fails in x86: 80040154 Class not registered

问题描述

我使用C ++中的下一个代码来使用WRL检索系统上的无线电设备

I use next code in C++ to retrieve the radio devices on the system using WRL

	RoInitializeWrapper initialize(RO_INIT_MULTITHREADED);
	ComPtr<IRadioStatics> radioFactory;
	HStringReference classId(L"Windows.Devices.Radios.Radio");
	HRESULT hres = RoGetActivationFactory(classId.Get(), __uuidof(IRadioStatics), &radioFactory);
	ComPtr<IAsyncOperation<__FIVectorView_1_Windows__CDevices__CRadios__CRadio*>> asyncOperation;
	hres = radioFactory->GetRadiosAsync(&asyncOperation);
	asyncOperation->put_Completed
	( 
		Callback<IAsyncOperationCompletedHandler< __FIVectorView_1_Windows__CDevices__CRadios__CRadio* >> 
		(
			[](IAsyncOperation<__FIVectorView_1_Windows__CDevices__CRadios__CRadio* >* pHandler, AsyncStatus status)
			{
				// check status and use the stream here
				return S_OK;
			}
		).Get()
	);
	ComPtr<__FIVectorView_1_Windows__CDevices__CRadios__CRadio> radios;
	hres = asyncOperation->GetResults(&radios);
	unsigned int num;
	radios->get_Size(&num);
	wprintf_s(L"Radio devices found: %u\n", num);

编译为x64时它工作正常并返回找到的蓝牙无线电设备。

It works fine when compiled for x64 and returns my bluetooth radio device found.

但在x86中，此代码会导致下一个调试错误：

But in x86 this code causes next debug errors:

...并返回任何设备。

... and any device is returned.

我们将不胜感激任何帮助。

Any help will be appreciated.

谢谢。

推荐答案

什么是IRadioStatics以及您创建了64位或32位的dll类型我认为由于混合模式而出现问题。确保在创建32位应用程序时也使用32位版本的IRadioStatics。

What is IRadioStatics and what type of dll you had created 64 bit or 32 bit I think you are getting issue due to mix mode . Make sure you are also using 32 bit version of IRadioStatics while creating your 32 bit app.

谢谢
