VS2010 开发 VB6.0 activeX控件 dll

项目源码

开发环境

操作系统: win7 64位 旗舰版

Java语言开发环境:  Eclipse3.7(jdk1.6u45)

C/C++语言开发环境:  cn_visual_studio_2010_ultimate_x86

VB语言开发环境:  VB6.0

前言

我们的项目主要以java为编写语言, 涉及到调用本地设备的底层模块使用的C/C++语言, java和C/C++之间利用JNI技术进行调用. 底层模块在和本地设备进行对接的方式之一是集成DLL(动态链接库)的形式.

前段时间项目中需要集成第三方厂家(Y厂)的DLL(YC.DLL), Y厂的DLL是使用VB编写的, 编译环境是VB6.0. 拿到DLL后, 先用Dependency Walker看了下内部的接口名称, 就四个:

DllCanUnloadNow

DllGetClassObject

DllRegisterServer

DllUnregisterServer

果然, 这就是传说中的activeX, 从网上的资料看, VB6.0编译出的dll均属于activeX控件.

至于DLL, OCX, activeX, COM组件概念上的区别, 网上都有很好的资料.

小插曲

刚拿到Y厂的YC.DLL后, 按照下一节的步骤, 在编译YC.DLL后, 编译器会提示”无法加载的动态库类型”, 而Y厂并没有相关的C/C++技术支持可以提供C/C++对他们的DLL的调用方式. 虽然自己之前也写过ocx控件, 将自己的ocx控件按照下一节的步骤, 编译一切正常. 但自己没有过在VB6.0编译器上通过VB语言进行开发的经验, 这让开发进度一再停滞.

后来偶然间在网页上查到一个在VS2010上引用VB6.0编译的dll的帖子, 截图如下:

按照图片所说的步骤, 我的vs2010竟然真的可以引用Y厂的dll.

关于vb6controls.reg可以参考:

集成方式-#import

语法:

#import "dllPath" no_namespace

使用#import语句, 然后对项目进行重新编译, 编译器会在工程目录下生成两个文件：YC.tlh与YC.tli, 其中YC.tlh文件类似于C/C++的头文件, 里面有dll接口声明:

struct __declspec(uuid("578277c2-7735-4c61-a141-1df16558cd4d"))

/* LIBID */ __SmartCardLib;

struct __declspec(uuid("fa7ab805-ec44-4a84-b876-52da8a5fe3c3"))

/* dual interface */ _clsSmartCard;

struct /* coclass */ clsSmartCard;

struct __declspec(uuid("ff073a9e-e768-4024-b9cf-bcc05efd1329"))

/* dispinterface */ __clsSmartCard;

_COM_SMARTPTR_TYPEDEF(_clsSmartCard, __uuidof(_clsSmartCard));

_COM_SMARTPTR_TYPEDEF(__clsSmartCard, __uuidof(__clsSmartCard));

struct __declspec(uuid("fa7ab805-ec44-4a84-b876-52da8a5fe3c3"))

_clsSmartCard : IDispatch

{

};

struct __declspec(uuid("5c4d3831-f09d-471b-82a0-0e84240c8afc"))

clsSmartCard;

struct __declspec(uuid("ff073a9e-e768-4024-b9cf-bcc05efd1329"))

__clsSmartCard : IDispatch

{

// Methods:

};

这个文件告诉我们两个非常重要的信息:

一是, 通过” struct /* coclass */ clsSmartCard;”这行代码, 得知YC.DLL的

CLSID(5c4d3831-f09d-471b-82a0-0e84240c8afc ), CLSID可以认为是对接YC.DLL的入口.

二是, 通过_clsSmartCard : IDispatch 和__clsSmartCard : IDispatch 得知

_clsSmartCard 和 __clsSmartCard是DLL内部的接口声明, 通过接口声明, 我们可以知道这个动态库为我们提供了哪些功能.
