实际上，您可以实现这一点，但是有一定的局限性.

Actually you can achieve this, but has some limitation.

例如，您可以在应用程序中嵌入MS word. Word窗口作为子窗口嵌入到您的应用程序中.但实际上，还有另一个进程winword.exe.

For example, you can embed MS word in your app. The Word window is embedded as a child window in your app. but actually, there is another process winword.exe.

您的应用充当复合文档容器，嵌入式应用充当复合文档服务器.

Your app works as compound document container and the embedded one act as compound document server.
