Sorry for this dumb question but

It appears that you have to send a message to the control first to begin
receiving Chnage messages from it. I'm not at my normal computer at the moment so
I can't look up the values you need until later today, but it should look like
...
VOID = sendMessage(myRichEdit, EM_SETEVENTMASK, 0, ENM_CHANGE)
I need to lookup the values for EM_SETEVENTMASK and ENM_CHANGE.
This will be fixed up for future releases of the Win32lib library such that its
done automatically for all rich edit controls.

WM_USER = #0400,
EM_SETEVENTMASK = (WM_USER + 69),
ENM_CHANGE = #00000001

Ok, I've found the fix required. You have to add two lines to win32lib.ew ...
Find the line ...
{EDIT,EN_CHANGE}, -- editbox notify change
and add this line after it ...
{COMMON_CONTROL,EN_CHANGE}, -- richedit notify change
Then find the line ...
{w32HChange, w32CHG_Chg}, -- editbox notify change
and add this line after it ...
{w32HChange, w32CHG_Chg}, -- richedit notify change
This will get it working. I'll add this improvement to the library ASAP.
You will still need to send the EM_SETEVENTMASK message for now too.
