　　这个事情就是一个坑，耽误了两周时间，之前并没有做过ActiveX这玩意，现在客户需求如此，只能说是在网上看着教程做了。

　　事情是这样的，有一台海康威视的摄像头，客户需要一个ActiveX控件嵌入到网页中，通过点击按钮开始录制和结束录制来进行视频的录制和保存，关于海康摄像头的二次开发在此就不多说了，可以参考SDK中的说明。

　　直接上流程：

　　1.开发环境：

　　　　VS2010,这个打包方便，之前用VS2013打包的，总是调用不了，不知道原因是什么；SDK是32位的，用64位的在Winform中可以正常使用，在网页中使用控件时会报错。

　　2.新建项目：

　　　　新建一个类库项目，如下：

　　　　右键点击项目，添加“用户控件”，如下：

　　　　界面拖控件，如下：

　　　　控件代码如下，其中Guid是“工具”->“创建GUID”自动生成的，#region->#endregion折叠部分是实现的IObjectSafety接口

控件设计器代码

　　　　至此，此项目结束。

　　　　右键点击解决方案，添加新项目，如下，至于为什么建立两个项目，我一会儿在下面解释，

技术分享

　　　　在HkHelper项目中添加类CHCNetSDK.cs，此类是海康提供的，可以在官网找到

　　　　接下来，最重要的，项目属性设置如下，两个项目都要设置：

技术分享

技术分享

　　　　至此，自定义控件已经完成，接下来就是打包，新建一个安装项目：

技术分享

　　　　右键点击安装项目，“添加”->“项目输出”，并选择自定义控件的项目，然后确定

技术分享

 

 　　　　然后添加海康提供的SDK的库文件文件夹下的所有文件和文件夹到项目中，如下：

技术分享

　　　　然后生成项目，会生成setup.exe和SetupVideo.msi两个文件，然后用打包文件，把这两个文件打包称cab文件就OK了

 

 打包文件一共三个cabarc.exe、build.bat、install.inf

build.bat文件：

"cabarc.exe"  n VideoSetup.cab SetupVideo.msi install.inf

install.inf文件：

[version]
signature="$CHICAGO$"
AdvancedINF=2.0

[Setup Hooks]
hook1=hook1

[hook1]
run=msiexec.exe /i "%EXTRACT_DIR%\SetupVideo.msi" /qn

cabarc.exe是微软提供的工具

 

最后说一下为什么要分为两个项目去实现控件，那是因为如果在一个项目中的话，调用海康动态库的类CHCNetSDK.cs不能进行COM注册
