如何在Outlook上打开电子邮件正文？ [英] How do I get opened email body on Outlook?

问题描述

我想让Outlook打开电子邮件正文。使用下面的代码，我设法将pDispatch作为_MailItem类型。问题是，当我试图获得电子邮件正文时失败：

Hi,

I would like to get Outlook opened email body. Using code below, I managed to get pDispatch as _MailItem type. The problem is, it fails when I tried to get email body:

hr = pMailItem->get_Body(&messageBody); //failed here 

需要你们的建议。下面是我的代码片段：

Need suggestions from you guys. Below is snippet of my code:

case 0x0000fba7:
			if(pDispParams->cArgs <= 0)
				return E_INVALIDARG;
			else
			{
				HRESULT hr;
				IDispatch *pDispatch = pDispParams->rgvarg[0].pdispVal;
				BSTR szName;
				
				if(pDispatch)
				{
					LPTYPEINFO lpMyTypeInfo = NULL;
					hr = pDispatch->GetTypeInfo(0,0,&lpMyTypeInfo);
					if(lpMyTypeInfo != NULL)
						hr = lpMyTypeInfo->GetDocumentation(MEMBERID_NIL,&szName,0,0,0);
				}

				if (0 != strcmp("_MailItem",(char *)(_bstr_t)szName)) //confirmed
					break;

				Outlook::_MailItemPtr pMailItem = NULL;
				pDispatch->QueryInterface(__uuidof(_MailItemPtr), (void**)&pMailItem);

				if (pMailItem)
				{
					BSTR messageBody;
					hr = pMailItem->get_Body(&messageBody); //failed here
					
					if(FAILED(hr))
					{
						//hr returned error code seems random everytime i debug
					}
				}
			}
			break;

推荐答案

通过使用资源管理器获取Outlook解决。无法使用以前的方式获取邮件

Solved by getting Outlook using Explorer. Cannot get mail using previous way

IDispatch *pDispatch = pDispParams->rgvarg[0].pdispVal //can't use this

case 0x0000fba7:
			if(pDispParams->cArgs <= 0)
				return E_INVALIDARG;
			else
			{
				Outlook::_ApplicationPtr spApp("Outlook.Application");
				Outlook::_MailItemPtr spMailItem;
				IDispatch *pDispatch;
				HRESULT hr;
				long lll;
				variant_t vvv = 1;

				if (NULL == spApp)
				{
					hr = spApp.CreateInstance("Outlook.Application");
				}

				if (spApp)
				{
					Outlook::_ExplorerPtr spExplorer;
					hr = spApp->ActiveExplorer(&spExplorer);
					if (spExplorer)
					{
						Outlook::SelectionPtr spSel;
						hr = spExplorer->get_Selection(&spSel);
						hr = spSel->get_Count(&lll);
						if (spSel &&  lll == 1) // if only 1 selection
						{
							hr = spSel->Item(vvv, &pDispatch);
							pDispatch->QueryInterface(__uuidof(_MailItemPtr), (void**)&spMailItem);
							BSTR bbb;
							hr = spMailItem->get_Body(&bbb); //get email body
						}
					}
				}
			}
			break;
