1. Still having Win32lib problem
Hi,
Didn't get any answer to this before, but I still need it. I have been
unable to get text back out of a RichEdit control. I tried poking around
in win32lib.ew and w32dll.ew, but no luck so far.
I made a little test program in Judith's IDE:
sequence line,text
text={}
line=" This is some text to test RichEdit Control\r\n"
for i=1 to 10 do text&=line end for
setText(RichEdit2,text) --works fine
text={}
text=getRichText(RichEdit2,-1) -- FAIL text={32 }
The content of "text" is {32 } (first char).
I am surprised no one else has reported this problem, if it isn't somehow
just on my machine. Has anyone had success getting text from a RichEdit?

This has to do with the RichEdit class changing from WinXP SR1 onwards, so that
it expects strings in Unicode.
Have you tried using getStream instead? That should work fine.

Thank you, Craig. That did the trick -- onward!

This problem has been there for a long time already: precisely, since Microsoft
started to ship RichEdit controls v3.0 and higher, because they no longer store
text in UTF-8, but UTF-16 instead. You probably noticed that demos using RichEdit
controls weren't fully working.
The next version of win32lib will solve this; the fix was not trivial.

Hi CChris,
Thanks for the information on this. The update on win32lib will be most
welcome when it happens.
