Hi CChris,

In win32lib.ew, EN_CHANGE has been declared as #300, and I declared -

ENM_CHANGE = 1
EM_GETEVENTMASK = #0459
EM_SETEVENTMASK = #0469



I used EM_GETEVENTMASK and EM_SETEVENTMASK as follows:

In General area of window:

atom flags, void

flags = sendMessage(RichEdit41, EM_GETEVENTMASK, 0, 0)
flags = or_bits(flags, ENM_CHANGE) -- also tried EN_CHANGE
void = sendMessage(RichEdit41, EM_SETEVENTMASK, 0, flags)

In w32HChange area for RichEdit41:

procedure RichEdit41_onChange (integer self, integer event, sequence
params)--params is ()
	VOID = message_box("RichEdit Changed", "onChange", MB_ICONINFORMATION)
end procedure
setHandler( RichEdit41, w32HChange, routine_id("RichEdit41_onChange"))

But still I can not get the display from w32HChange event for RichEdit41.
Where am I going wrong?

Rad.
