問題描述
您可以將一個進程的 Direct3D 窗口渲染到另一個進程的 HWND 中嗎？ (Can you render a Direct3D window for one process into another process' HWND?)
我想做的是讓一個 Windows 應用程序啟動另一個 Direct3D 應用程序，並讓 Direct3D 應用程序呈現到父進程提供的控件中。
這可能嗎？如果是，怎麼做？
參考解法
方法 1:
It can be done easly, all you need to do is pass the HWND window id as a parameter when creating D3DDevice. It even works during interop ‑ you can pass the hWnd from .NET to C++ and render C# window using native directX.
方法 2:
Here's one example, hosting content of a WPF window in an existing Win32 window. I did this when writing a WPF‑based screen saver, having to render into the Screen Saver little preview window.

方法 3:
This is possible. I remember doing it in VB6 when writing screen savers. The screen saver control panel sends a commandline to the screen saver with the HWND of the preview window. Using that HWND, you can then get the HDC and from there everything else you need.
