RE: [GD-Windows] Finding HWND of the current thread

[Andrew G. <ag...@cl...>]

Couldn't you just create a simple hidden window and pass that handle in?

Really though if this is a library wouldn't you want to allow the user to
pass in a handle and handle the case of being a console app at a higher
level...

Subject: [GD-Windows] Finding HWND of the current thread

For my simple audio library I'm stuck doing something a little gross, and
that's passing an HWND to the library upon initialization, only because
IDirectSound::SetCooperativeLevel() needs an HWND.

Now, you CAN use GetDesktopWindow() and NULL, but that's not the correct way
and there are supposedly some failure cases when you use those (e.g.
multiple instances using GetDesktopWindow()), and God knows what the HWND is
really used for in DirectSound and what can happen if you do something like
create a hidden window and bind DS to that instead of to your real
application window.

Anyway, that aside, instead of passing in HWND, I was thinking it might be
possible to find the window of the current thread by enumerating all windows
in the system and comparing their owner threads with the current thread and
using that.

Is there anything glaringly wrong with that, other than the potential
situation that there is none (e.g. console application) and having to
fallback at that point.
