vb6集成环境on error错误处理代码添加插件

插件下载地址（请下载最新版v1.0.5）：

http://code.google.com/p/vsaddin/downloads

安装方法：
1.点击菜单“工程-引用”，选择这个dll
2.然后点击菜单“外接程序-外接程序管理器”，选择“Insert Error Hand”，把右下角两个框框都勾起来
3.这样你的菜单“外接程序”中就会多出“Insert Error Hand”这一项

使用方法：
将要处理的代码编辑窗口打开，然后点击菜单“外接程序-Insert Error Hand”

ps：插件会只会处理已经打开的代码编辑窗口

主要代码如下：
