调用videocapX.ocx控件遇到的问题

最近准备用到摄像头，根据以前论坛上的那个貌似有时候摄像头显示不了，下载这个控件的示例发现每次能完美解决， 所以想要封装下这个控件。
我声明了个库：videoX.aardio
import util.metaProperty;
class videoX{
ctor(winform){
this = winform.createEmbed("{912FB007-DD9A-11D3-BD8D-DAAFCB8D9378}");
};
aboutBox = function(){
this._object.AboutBox();
};
@_metaProperty;
}
namespace videoX{
_metaProperty = ..util.metaProperty(
connected = {
_set = function( v ){
owner._object.Connected = v;
}
};
preview = {
_set = function( v ){
owner._object.Preview = v;
}
};
)
}调用的时候：
import win.ui;
import win.ui.ctrl.afvideocapture;
/*DSG{{*/
var winform = win.form(text="视频捕获控件";right=614;bottom=487;parent=...)
winform.add(
custom={cls="custom";text="custom";left=27;top=11;right=587;bottom=366;z=1}
)
/*}}*/
winform.show()
import console
console.open()
import videoX;
var vdx = videoX(winform.custom);
vdx.aboutBox()
vdx.connected = true;
vdx.preview = true;
win.loopMessage();那个aboutbox弹出信息框倒是对了，后面根据官方文档来写怎么弄都出不来摄像图像，唉
错误提示：

这里是按照文档写的，为什么会有这个提示呢？

貌似这个是vb的标准控件，会在vs的控件栏里出现这个控件图标，这种的aar应该怎么调用
我今天给我们公司用vb.net的人说，他们说这个是标准控件，会在vs控件栏生成一个标准摄像头控件，然后拖上去就可以了，感觉和aar的自定义控件很像啊
这个com控件里面用的是dispinterface接口
网上搜了下，貌似说是利用事件驱动，接口有点区别
