通过上面这些步骤，向导已经为我们创建了代码的大致框架。我们只需要添加几行代码，完成文本的复制然后通过事件通知Web页面就可以了。编辑文件MyActiveXCtrl.cpp，在函数LoadParameter中添加如下的代码：
// 将文本从输入参数复制到输出参数
m_OutputParameter = m_InputParameter;
// 触发一个事件通知Web页面
FireParameterLoaded();
为了测试ActiveX控件和Web页面之间的通信，使用ActiveX Control Pad创建如下的HTML代码：
<HTML>
<HEAD>
<TITLE>MyActiveX - Methods, Properties, and Events</TITLE>
<SCRIPT LANGUAGE="JavaScript">
function PassParameter()
{
if (StringInput.value != " ")
{
MyActiveX1.InputParameter = StringInput.value;
MyActiveX1.LoadParameter();
}
}
</SCRIPT>
</HEAD>
<BODY>
<center>

<p></p>
<OBJECT ID="MyActiveX1" WIDTH=350 HEIGHT=50

<PARAM NAME="_ExtentY" VALUE="1323">
<PARAM NAME="_StockProps" VALUE="0">
</OBJECT>
<p></p>

<INPUT TYPE="button" NAME="Submit"

<!-- {

-->
</SCRIPT>
</center>
</BODY>
m_OutputParameter = m_InputParameter;
// 触发一个事件通知Web页面
FireParameterLoaded();
