VS2010與PB10開發(fā)和使用PBNI-初步使用3

1、PBNI初步使用三（函數(shù)功能調(diào)用-代碼優(yōu)化）下面講解如何使用VS2010開發(fā)PB10.5版本PBNI組件應(yīng)用實(shí)例：在VS中創(chuàng)建一個(gè)f_add的函數(shù),實(shí)現(xiàn)2個(gè)int類型的數(shù)值進(jìn)行相加。PB調(diào)用和使用這個(gè)函數(shù)功能代碼的優(yōu)化。1 優(yōu)化和使用PBNIADD代碼將項(xiàng)目管理中多余的文件進(jìn)行刪除，系統(tǒng)僅僅只是留下3個(gè)主要的文件。Stdafx.h,PBNIAdd.cpp和PBNIAdd.h這三個(gè)文件。如下圖:stdafx,.h代碼主要定義生成DLL文件的入口。代碼如下：#pragma once#ifndef STRICT#define STRICT#endif#ifndef WINVER#define WIN

2、VER 0x0400#endif#ifndef _WIN32_WINNT#define _WIN32_WINNT 0x0400#endif#define VC_EXTRALEAN/ Exclude rarely-used stuff from Windows headers/Pull in support for Commctrl v6#ifdef _UNICODE#if defined _M_IX86#pragma comment(linker,/manifestdependency:type=win32 name=Microsoft.Windows.Common-Controls vers

5、ssorArchitecture=* publicKeyToken=6595b64144ccf1df language=*)#endif#endifPBNIApp.h代碼主要聲明類和函數(shù)。代碼無須變化，代碼如下：class PBNIAdd: public IPBX_NonVisualObjectpublic:PBNIAdd();virtual PBNIAdd();PBXRESULT Invoke(IPB_Session *session,pbobject obj,pbmethodID mid,PBCallInfo *ci);int f_add(IPB_Session*, pbint, pbin

6、t);/ Enum used to provide entry points for each method in the class - this case is mAddenum MethodIDsmAdd = 0;private:virtual void Destroy();點(diǎn)擊PBNIApp.cpp代碼主要聲名定義和具體函數(shù)。之前對(duì)應(yīng)dllmain.cpp合并在里面，代碼如下：/ PBNIADD.cpp : 定義 DLL 應(yīng)用程序的導(dǎo)出函數(shù)。/ Implement the required Invoke method#include #include stdafx.h#include

7、PBNIAdd.h#include BOOL APIENTRY DllMain( HMODULE hModule, DWORD ul_reason_for_call, LPVOID lpReserved )switch (ul_reason_for_call)case DLL_PROCESS_ATTACH:case DLL_THREAD_ATTACH:case DLL_THREAD_DETACH:case DLL_PROCESS_DETACH:break;return TRUE;PBXEXPORT LPCTSTR PBXCALL PBX_GetDescription()static const
