如何使用C ++创建Outlook插件 [英] How to create Outlook addin using C++
本文介绍了如何使用C ++创建Outlook插件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在创建一个ATL项目并创建类，以便我为该类实现了_MailItem接口。我无法访问那些接口函数，如get_Attachments，get_CC等...
_IDTExtensibility2方法可以访问但_MailItem方法无法访问。我想在发送邮件时访问邮件，以便我需要获取正文，To，Cc，subject&在使用C ++发送邮件之前来自outlook的邮件附件？
如何使用C ++访问这些函数？
在此先感谢Swathi
这是我的代码：
I'm creating an ATL project and creating class so that i have implemented the _MailItem interface for that class. I m not able to access those interface functions such as get_Attachments, get_CC etc...
_IDTExtensibility2 methods can able to access but _MailItem methods not able to access. I want to access mail items when sending mail so that i need to get body, To, Cc, subject & attachments of mail from outlook before sending mail using C++?
How to access these functions using C++?
Thanks in advance Swathi
Here is my Code:
#pragma once
#include "resource.h" // main symbols
#include "NativeAddIn_i.h"
#if defined(_WIN32_WCE) && !defined(_CE_DCOM) && !defined(_CE_ALLOW_SINGLE_THREADED_OBJECTS_IN_MTA)
#error "Single-threaded COM objects are not properly supported on Windows CE platform, such as the Windows Mobile platforms that do not include full DCOM support. Define _CE_ALLOW_SINGLE_THREADED_OBJECTS_IN_MTA to force ATL to support creating single-thread COM object's and allow use of it's single-threaded COM object implementations. The threading model in your rgs file was set to 'Free' as that is the only threading model supported in non DCOM Windows CE platforms."

推荐答案
你不需要实现应用程序和MailItem接口。
相反您必须使用现有的Outlook界面。
在发送邮件之前访问邮件您必须订阅Outlook :: ItemEvents调用IDispEventSimpleImpl< ...> :: DispEventAdvise函数。
头文件
You dont need to implement Application and MailItem interfaces.
Instead You have to use existing Outlook interfaces.
To access mail items before sending mail You have to subscribe on Outlook::ItemEvents calling IDispEventSimpleImpl<...>::DispEventAdvise function.
Header File

现在从这段代码我得到suject，to，cc，bcc以及附件名但是im没有从get_PathName函数获取附加文件路径，它显示空白消息框...如何从此获取附加文件路径..让我知道是否有任何其他方式来获取文件路径以及如何获取文件姓名和附件路径如果有多个附件......请帮助我...
提前致谢
Now from this code i m getting suject, to, cc, bcc and also the attached file name but i m not getting the attached file path from get_PathName function, its showing blank message box... How to get the attached file path from this.. let me know if there is any other way to get the file path and also how to get the file names and attachments path if there is more than one attachment..Pls help me in this..
Thanks in advance
请按照以下步骤操作：您将能够检索：
//在定义addin接口的类中
public IDispEventSimpleImpl< 17，CAddin，& __ uuidof（Outlook :: ApplicationEvents_11）>
_ATL_FUNC_INFO OnNewMail = {CC_STDCALL，VT_EMPTY ，1，{VT_BSTR}};
SINK_ENTRY_INFO（17，__ uuidof（Outlook :: ApplicationEvents_11），0xfab5，OnNewMailEx，& OnNewMail）
//标题文件函数声明
STDMETHOD_（void，OnNewMailEx）（BSTR bstrEntryID）;
// CPP文件函数定义
STDMETHODIMP_（void）CAddin :: OnNewMailEx（BSTR bstrEntryID）
{
ATLTRACE（NewMail Entryid是％S \ n ，bstrEntryID）;
CComPtr< outlook :: _ namespace xmlns：outlook =＃unknown> pNameSpace;
HRESULT hr = E_FAIL;
hr = m_pApp-> get_Session（& pNameSpace ）;
if（pNameSpace）
{
CComPtr< outlook :: _ store> pStore;
hr = pNameSpace-> get_DefaultStore（& pStore）;
if（pStore ）
{
CComBSTR storeID;
CComVariant vStore;
CComPtr< idispatch> pItemDisp;
CComQIPtr< outlook :: _ mailitem> pMailItem;
hr = pStore-> get_StoreID（& storeID）;
vStore = storeID ;
hr = pNameSpace-> GetItemFromID（bstrEntryID，vStore，& pItemDisp）;
pMailItem = pItemDisp;
if（pMailItem）
hr = pMailItem->显示（）;
}
}
}
Please follow below steps: you will able to retrieve:
//In Class that defines addin inteface
public IDispEventSimpleImpl<17, CAddin, &__uuidof(Outlook::ApplicationEvents_11)>
_ATL_FUNC_INFO OnNewMail = {CC_STDCALL, VT_EMPTY, 1, {VT_BSTR}};
SINK_ENTRY_INFO(17, __uuidof(Outlook::ApplicationEvents_11), 0xfab5, OnNewMailEx, &OnNewMail)
//Header file function declaration
STDMETHOD_(void, OnNewMailEx)(BSTR bstrEntryID);
//CPP file function definition
STDMETHODIMP_(void) CAddin::OnNewMailEx( BSTR bstrEntryID )
{
ATLTRACE("NewMail Entryid is %S\n", bstrEntryID);
CComPtr<outlook::_namespace xmlns:outlook="#unknown"> pNameSpace;
HRESULT hr = E_FAIL;
hr = m_pApp->get_Session( &pNameSpace );
if( pNameSpace )
{
CComPtr<outlook::_store> pStore;
hr = pNameSpace->get_DefaultStore( &pStore );
if( pStore )
{
CComBSTR storeID;
CComVariant vStore;
CComPtr<idispatch> pItemDisp;
CComQIPtr<outlook::_mailitem> pMailItem;
hr = pStore->get_StoreID( &storeID );
vStore = storeID;
hr = pNameSpace->GetItemFromID( bstrEntryID, vStore, &pItemDisp);
pMailItem = pItemDisp;
if(pMailItem)
hr = pMailItem->Display();
}
}
}
