使用.net创建activex控件
1. . 创建.net activeX
示例: http://www.codeproject.com/cs/miscctrl/exposingdotnetcontrols.asp
首先要在类定义前面添加:
[ProgId("MyClassName")] COM调用名称
[Guid("MyGUID")] sdf COM对应的GUID
[ComVisible(true)] 是否为COM组件
activeX自注册方法:
///<summary>
///Register the class as a control and set its CodeBase entry
///</summary>
///<param name="key">The registry key of the control</param>
[ComRegisterFunction()]
public static void RegisterClass ( string key )
{
.
.
}
///<summary>
///Called to unregister the control
///</summary>
///<param name="key">Tke registry key</param>
[ComUnregisterFunction()]
public static void UnregisterClass ( string key)
{
.
.
}
然后可以用: regasm /codebase MyAssemblie.dll 注册此activex或 regasm /u MyAssemblie.dll 反注册此DLL
其中activeX中调用的方法需要添加[ComVisible(true)]
最后再建立一个SNK文件: sn –k Kosmala.Michal.ActiveXReport.snk
并添加到assemblyinfo.cs中.
[assembly:AssemblyKeyFile("http://www.cnblogs.com/Kosmala.Michal.ActiveXReport.snk")]
生成并注册activeX之后,就可以在HTML中用JS调用了.
示例:
<body onload="OpenActiveX()">
<!-- Our activeX object -->
<OBJECT id="OurActiveX" name="ourActiveX" classid="clsid:121C3E0E-DC6E-45dc-952B-A6617F0FAA32" VIEWASTEXT codebase="OurActiveX.cab"></OBJECT>
<!-- Attaching to an ActiveX event-->
<script language="javascript">
function OurActiveX::OnClose(redirectionUrl)
{
alert(redirectionUrl); <!-- http://otherwebsite.com should be returned-->
//window.location = redirectionUrl;
}
</script>
<script language="javascript">
//Passing parameters to ActiveX object and starting application
function OpenActiveX()
{
try
{
document.OurActiveX.MyParam = "Hi I am here." //Passing parameter to the ActiveX
document.OurActiveX.Open(); //Running method from activeX
}
catch(Err)
{
alert(Err.description);
}
}
</script>
</body>
如果要更友好的使用,则应该建立一个cab文件,放在html文件目录下,这样访问此HTML,而找不到ACTIVEX时,会自动提示安装此CAB.
