Subclassing

[Guest]

Hi,

I need to subclass a form; i.e. I want to catch wm_ messages. I tried to use
::SetWindowLong(hwnd, GWL_WNDPROC, myDelegate) but without succeess: it gives
NotSupportedException at runtime.

Is it possible at all?

The only to way in CF v1 to get window subclassing is using IMessageFiter and
ApplicationEx from SDF:

It gets better with CF v2 that supports delegates as native callbacks:
