How to move the IME window?

[Lloyd Dupont]

I have developed a text editor supporting international languages.
One problem still bother me: The location of the IME window.

When I have an asian user entering asian characters, (s)he does so through
an IME window which is located in a seemingly unpredictable/uncontrollable
location.

Is there a way I could set the location, size, and font (or at least font
size) used by this IME window?
How could I know when it is used or not?

AFAIK, there's no way to do it with native code as this is OS controlled.
However, you can use the SendMessage Win32 API call, with the WM_IME_CONTROL
message
(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/intl/ime_8awc.asp),
and the IMC_SETCOMPOSITIONWINDOW
(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/intl/ime_8wjb.asp)
and the COMPOSITIONFORM structure,
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/intl/ime_8vle.asp
as parameters.
