引言
跟著信息化時代的到來，郵件處理已成為壹般任務中弗成或缺的一部分。Outlook作為一款風行的郵件客戶端，供給了豐富的API介面，使得開辟者可能經由過程編程方法實現郵件的主動化處理。本文將介紹怎樣利用C言語輕鬆接入Outlook API，解鎖郵件處理功能。
一、懂得Outlook API
Outlook API是基於COM（Component Object Model）的，它容許開辟者經由過程編程方法把持Outlook的功能。要利用Outlook API，起首須要懂得COM的不雅點。
1. COM概述
COM是一種組件技巧，它容許差其余利用順序之間停止交互跟數據共享。Microsoft Office套件，包含Outlook，供給了COM介面，使得開辟者可能經由過程編程方法把持其功能。
2. Outlook COM介面
Outlook供給了豐富的COM介面，包含郵件、日曆、聯繫人等模塊。經由過程這些介面，開辟者可能實現郵件的創建、編輯、發送、接收等功能。
二、C言語接入Outlook API
要在C中利用Outlook的COM介面，你須要包含須要的頭文件並鏈接到響應的庫。
1. 包含頭文件
#include <windows.h>
#include <outlook.olb>
2. 初始化COM情況
CoInitialize(NULL);
3. 實例化Application東西
LPDISPATCH pDispatch;
HRESULT hr = CoCreateInstance(CLSIDApplication, NULL, CLSCTXALL, IIDIDispatch, (LPVOID)&pDispatch);
4. 創建郵件東西
COleDispatchPtr spOutlook;
spOutlook = COleDispatchPtr(pDispatch);
COleDispatchPtr spNamespace;
spNamespace = spOutlook->GetNamespace("MAPI");
COleDispatchPtr spSession;
spSession = spNamespace->GetSession();
COleDispatchPtr spFolder;
spFolder = spSession->GetDefaultFolder(OlDefaultFolders::olFolderInbox);
5. 創建郵件並設置屬性
”`cpp COleDispatchPtr spItem; spItem = spFolder->CreateItem(OlItemType::olMailItem); COleDispatchPtr spInspector; spInspector = spItem->GetInspector(); COleDispatchPtr spInspectorUI; spInspectorUI = spInspector->GetInspectorUI();
