处理 C# ActiveX 控件中的父控件事件
我用 C# 编写了一个 ActiveX 用户控件。该 ActiveX 控件托管在用 Delphi 编写的 IE 中运行的旧应用程序内。 一切正常，我唯一的问题是我需要订阅托管我的控件的事件（例如 - 调整大小事件）。
目前我无法做到这一点，当我调整 IE 窗口大小时，我的控件没有收到 SizeChanged 事件。我尝试订阅父控件的事件，但父控件被列为空。 （我猜这是 Delphi 的问题。）
我想知道是否有办法让它工作（也许我必须实现一些接口？）。
这是我的控件的代码示例：
[
ClassInterface(ClassInterfaceType.AutoDispatch),
ComVisible(true),
Guid("<some guid>"),
]
public partial class MyActiveXControl : UserControl, IMyInterface
{
public MyActiveXControl()
{
InitializeComponent();
}
#region IScriptViewer Members
//implement interface
#endregion
}
I have written an ActiveX user control in C#. That ActiveX control is hosted inside a legacy application running in IE that is written in Delphi.
Everything works, my only problem is that I need to subscribe on events of the control that is hosting me (for example - resize event).
Currently I am unable to do that, and when I resize the IE window, my control does not get a SizeChanged event. I tried to subscribe on the parent control's events, but the parent control is listed as null. (I guess it's the Delphi issue.)
I want to know if there is a way to get this working (some interface I have to implement maybe?).
Here is an example of the code of my control:
[
ClassInterface(ClassInterfaceType.AutoDispatch),
ComVisible(true),
Guid("<some guid>"),
]
public partial class MyActiveXControl : UserControl, IMyInterface
{
public MyActiveXControl()
{
InitializeComponent();
}
#region IScriptViewer Members
//implement interface
#endregion
}

您如何处理网页中的控件大小？例如，获取浏览器窗口大小/changes，然后设置边界的手动控制。如果您希望控件内的控件重新排列它们，那么可能会调用控件的 OnSize 事件。
How about you handle the control size in your WebPage. For instance, get the browser window size/changes, and then set the bounds of control manually. And if you want the controls within the control the re-arrange them, then probably call the OnSize event of the control.
