Questions about Vista tablet input keyboard and digitizer device. 選項

[bens...@gmail.com]

Hi,

I have some problems about driver and tablet function.

I wrote a hid digitizer driver for touch panel, and the touch
function
works fine on vista.
Vista will enable tablet input tab when there is a digitizer device
attached to system.

I have declare "In-range" in the report descriptor.
There are 2 cases, please take a look to image link:

case 1:
I report touch packets to Vista with In-range flag set, and open the
tablet on-screen keyboard:

case 2:
Report touch packets without In-range flag, and open the tablet on-
screen keyboard:
http://benstang.myweb.hinet.net/vista/noinrange.jpg

My problem is why the on-screen keyboards are different?
These 2 cases are the same but In-range flag.
Is there any config or settings can change layout of on-screen
keyboard?

I found a similar question on internet:
http://www.technologyquestions.com/technology/windows-xp-tablet-pc-newsgroup/164425-input-panel-keyboard-changes-when-i-use-pen.html

But the discuss thread ends with no result.

Any advise would be greatly appreciated.
Thank you for reading this post, and sorry for my poor English =)
