Is there an XEmbed equivalent in Windows?

XEmbed is used to embed an X11 window in an other application. This is done by reparenting the target window.

Is there a windows equivalent to be able to embed an external window into an other one? In my case, I have control on both applications/开发者_开发技巧windows so cooperation is possible.
