的ActiveX初始化：AxHost.State对象 [英] ActiveX initialization: AxHost.State object

问题描述

我想用WinFormsHost控制嵌入Unity3D，ActiveX控件到WPF表格。

I'm trying to embed a Unity3D-ActiveX control into a WPF-Form by using a WinFormsHost-Control.

其实它运作良好，设置路径VS的属性窗口时，但设置它，当我在code文件时，它不会加载任何东西。这是控制的一个已知的问题，但我想我可以简单地复制的形式，设计师的创作code和手动初始化。

Actually it works well when setting the path in the property window of VS, but when setting it in my code file it does not load anything. This is a known issue of the control but i thought i can simply copy the creation code of the forms-designer and initialize it manually.

当在初始化我注意到的code看有没有的src 属性在code，但物业用于物业窗口。设置该属性手动不起作用（抛出一个错误）。

When looking at the code of the initialization i noticed that there is no src property in the code, but the property is used in the property window. Setting the property manually does not work ( throws a error ).

在一些测试的，我决定检查钻具组合为的src 属性，但的src 属性是永远设置和我甚至找不到路径的字符串。

After some test's i decided to check the hole assembly for the src property, but the src property is never set and i can't even find the string of the path.

我注意到，只能有一个地方的SRC路径位于：由窗口窗体设计器生成的资源，这是的 AxHost.State 型。

I noticed that there can be only one place where the src-path is located: The resource generated by the window forms designer, which is a object of the AxHost.State-type.

我如何建立一个有效的 AxHost.State 对象初始化Unity3D，ActiveX控件应该加载指定的Unity3D文件由我？

How do i create a valid AxHost.State object to initialize the Unity3D-ActiveX control which should load a Unity3D-file specified by me?

推荐答案

这是它的工作原理，但有一点慢（注意解决方案：你需要在窗体设计器，一旦初始化控制和OcxState对象复制到集资源）：

This is the solution which works but is a little bit slow( Note: You need to initialize the Control once in the Forms Designer and copy the OcxState object into the assembly resources ):

// Create a ocx state object with the correct path
_Unity = new AxUnityWebPlayerAXLib.AxUnityWebPlayer();
((System.ComponentModel.ISupportInitialize)(_Unity)).BeginInit();
_Unity.OcxState = (AxHost.State)(Resources.Unity3DOcx);
_Unity.TabIndex = 0;
Controls.Add(_Unity);
((System.ComponentModel.ISupportInitialize)(_Unity)).EndInit();
_Unity.src = _File;
AxHost.State state = _Unity.OcxState;
_Unity.Dispose();

// Create the unity web player object
_Unity = new AxUnityWebPlayerAXLib.AxUnityWebPlayer();
((System.ComponentModel.ISupportInitialize)(_Unity)).BeginInit();
this.SuspendLayout();
_Unity.Dock = DockStyle.Fill;
_Unity.Name = "Unity";
_Unity.OcxState = state;
_Unity.TabIndex = 0;
Controls.Add(_Unity);
((System.ComponentModel.ISupportInitialize)(_Unity)).EndInit();
this.ResumeLayout(false);
