C++CLI调用ArcObjects (2)

修改头文件stdafx.h，导入ArcObjects相关库

// stdafx.h : include file for standard system include files, // or project specific include files that are used frequently, but // are changed infrequently //

#pragma once

#include \

#define WIN32_LEAN_AND_MEAN // Exclude rarely-used stuff from Windows headers

// Windows Header Files: #include

// TODO: reference additional headers your program requires here #pragma warning(push)

#pragma warning(disable : 4192) /* Ignore warnings for types that are duplicated in win32 header files */

#pragma warning(disable : 4146) /* Ignore warnings for use of minus on unsigned types */

#import \ raw_interfaces_only, raw_native_types, no_namespace, named_guids, exclude(\, \, \)

#import \ raw_interfaces_only, raw_native_types, no_namespace, named_guids,exclude(\) // Load the ArcGISVersion library.

// This code is commonly placed in the StdAfx.h header file. #import \ raw_interfaces_only,no_implementation

添加一个头文件NAoHelper.h

修改后的头文件如下：

#ifndef AOHELPER_H_ #define AOHELPER_H_ #ifdef NAOHELPER_EXPORTS

#define DAPI __declspec(dllexport) #else

#define DAPI __declspec(dllimport) #endif

//导出这个类

class DAPI AoHelper { public: }; #endif

AoHelper(); ~AoHelper(); int line_test(); int InitializeAo();

private:

打开NAoHelper.cpp，修改后如下：

// NAoHelper.cpp : Defines the exported functions for the DLL application. //

#include \ #include \

AoHelper::AoHelper() { }

AoHelper::~AoHelper() { }

int AoHelper::InitializeAo() {

esriLicenseStatus ls; HRESULT h=

IAoInitializePtr m_AoInit;//(CLSID_AoInitialize); m_AoInit.CreateInstance (CLSID_AoInitialize); ArcGISVersionLib::IArcGISVersionPtr VARIANT_BOOL succeeded;

if (FAILED(ipVer->LoadVersion(ArcGISVersionLib::esriArcGISDesktop ,

return 0;

ipVer(__uuidof(ArcGISVersionLib::VersionManager));

::CoUninitialize(); ::CoInitialize(NULL); //不初始化也可以 //InitializeAo();

L\,&succeeded)))

m_AoInit->Initialize(esriLicenseProductCode::esriLicenseProductCodeEngineGeoDB ,&ls); }

int AoHelper::line_test() {

IPointPtr ipPt1(CLSID_Point); IPointPtr ipPt2(CLSID_Point); ipPt1->PutCoords(1, 2); ipPt2->PutCoords(2, 3); return 0;

}

ILinePtr ipLine(CLSID_Line);

for(long i = 0; i <= 10000000; i++) { }

return 0;

ipLine->PutCoords(ipPt1,ipPt2);

编译，完成本地c++调用AO封装类库

4 添加新项目，命名为NAoWrapper，利用C++/CLI对NAoHelper进行封装的库，以便于C#调用

编辑包含文件（头文件）目录

修改头文件NAoHelper.h

// NAoWrapper.h
