Having my HWND and eating it, too... [message #12095]

I have a problem.

I'm not using an OCX control. I'm not using OLE or COM in any form for this. I have a function to a third-party library that takes a HWND as its argument.

The HWND needs to represent an area within a TopWindow to which the third-party library may render whatever it wants.

I created a custom class derived from Ctrl, but quickly discovered that Ctrl objects do not have their own HWNDs.

So, I tried creating deriving the class from TopWindow instead, after noticing all the happy fun function for creating HWNDs there. However, for some reason, when I call GetHWND() against this control, I still get a null.

So I'm stumped. At the moment, I am not sure how I should create this window. I've tried some other things, but they lead to assertions.

Does anyone have anything to suggest?
