1. 定义事件接收器

#pragma once

#pragma warning (disable : 4146)

#import "F:xproeratlup6codex86atlobjDebugHttpUploaderApp.tlb" named_guids, raw_interfaces_only

#include "HttpUploaderApp_i.h"

class up6Event : public IDispEventImpl<0,up6Event,&DIID__IHttpPartitionEvents,&LIBID_HttpUploaderAppLib,1,0>

{

public:

up6Event();

~up6Event();

STDMETHOD(recvMessage)(BSTR msg);

BEGIN_SINK_MAP(up6Event)

SINK_ENTRY_EX(0, DIID__IHttpPartitionEvents, 1, recvMessage)

END_SINK_MAP()

};

.cpp代码

#include "stdafx.h"

#include "up6Event.h"

up6Event::up6Event(){}

up6Event::~up6Event(){}

STDMETHODIMP up6Event::recvMessage(BSTR msg)

{

MessageBoxW(nullptr, L"recvMessage", L"", MB_OK);

return S_OK;

}

2.打开文件选择窗口，并触发recvMessage事件

LRESULT CMainDlg::openFile_click(WORD /*wNotifyCode*/, WORD wID, HWND /*hWndCtl*/, BOOL& /*bHandled*/)

{

CLSID clsid;

HRESULT hr = ::CLSIDFromProgID(L"Xproer.HttpPartition6.1", &clsid);

if (!SUCCEEDED(hr))

{

MessageBoxW(L"创建组件失败，请先安装或注册组件", L"错误", MB_OK);

return 0;

}

CComPtr < IUnknown > spUnk;

hr = ::CoCreateInstance(clsid, NULL, CLSCTX_ALL, IID_IUnknown, (LPVOID *)&spUnk);

CComDispatchDriver up6 = spUnk;

//创建事件接收器

auto ent = std::make_shared<up6Event>();

ent->DispEventAdvise(spUnk);

CComVariant version;

up6.GetPropertyByName(L"Version", &version);

std::wstring js = L"{"name":"open_files"}";

CComVariant v1(js.c_str());

CComVariant ret;

hr = up6.Invoke1(

L"postMessage",

&v1,

&ret);

ent->DispEventUnadvise(spUnk);

return 0;

}

运行

点击选择文件按钮，选择文件

触发事件，显示选择结果
