WPF页面嵌入exe文件，怎样控制嵌入文件窗体的缩放比例？

[ylly2508]

在页面上做了一个 Border 控件，将.exe文件打开后，将接收到的窗口句柄放到 Border控件中，但是当放大缩小Border的时候.exe窗体始终保持原大小，这个是为什么~？

我想让.exe文件的窗口，始终保持和border控件的大小一样，也跟着缩放~~能办到么？？

还请高手指点下~~！

以下是部分代码：

使用Border控制应用窗口缩放比较困难。我看到过ZoomPanel可以实现你的需求。

这个控件是，在控件的内部控制应用程序的窗口吧~~~我想实现的是，让窗口随着控件的缩放自动缩放，可以办到么？？

[ylly2508]

我写的时候为什么提示

xml 命名空间 “clr-namespace:Ab2d.Controls;assembly=Ab2d.Controls.ZoomPanel” 中不存在标记 “ZoomPanel” ????

请问要加什么引用么？？

顶~~！

ZoomPanel是自定义控件，需要添加引用，安装该控件。

先谢谢楼上的帮助~~~ZoomPanel的dll我找到了~~也测试了~~~这个控件是放入一个xaml页面的~~要指定页面的路径，并不能赋一个窗口句柄~~~

我前面代码中 hwndHost = FindTheWindow( ); 是找到一个窗口句柄~~

控制一个窗口句柄这么难么~？？？
