上面是EmbeddedApp.cs内容

下面是窗体.cs代码。
string formName;
String path;

formName = "Island Demo";
path = Environment.CurrentDirectory + "\\" + "3D Demo\\app.exe";

EmbeddedApp ea = new EmbeddedApp(WndHost, this.Width, this.Height, path, formName);
WndHost.Child = ea;
可以运行出


但是鼠标和键盘全部失效。根本操作不了这个窗体。
谁有好办法吗？

这个人说有办法。可是他的说【Win32Native .cs是我们写的一个对Win32API的调用声明，都是简单的PInvoke声明，由于尺寸比较大这里就不贴出来了，大家可以查MSDN自己来声明。】

你好我会报错误：寄宿的 HWND 必须是指定父级的子窗口。

我的也会报这个错误，请问你解决了没
