Cannot Switch the Hangul/English Key By Using the RDP Client (320005)


The information in this article applies to:

  • Microsoft Windows CE .NET Operating System
This article was previously published under Q320005

SYMPTOMS

When you are using a Windows CE .NET RDP client with a Korean language terminal server, the Hangul/English key does not change the input mode of the input method editor (IME). This prevents you from typing Hangul or English characters in the remote program.

CAUSE

The Korean keyboard has two keys that require special consideration in software because they do not generate virtual key codes when they are released. The previous RDP code did not handle this circumstance correctly.

RESOLUTION

A supported fix is now available from Microsoft as Windows CE Core OS QFE . To resolve this problem immediately, search for the keyword "QFE" on the following Microsoft Web site:

MORE INFORMATION

The following entry is also necessary in the Rdp.reg file:

IF LOCALE=0412
; Fill in correct keyboard type and subtype values depending on the keyboard

[HKEY_LOCAL_MACHINE\Software\Microsoft\Terminal Server Client]

"Keyboard Type"=dword:8

"Keyboard SubType"=dword:2

"Keyboard FunctionKeys"=dword:c

ENDIF

You may also have to update the keyboard driver that is located in the public\common\oak\csp\HD64465\keymse2\ps2keybd.cpp file if you use a platform that includes it. The following section is the section you have to change. The modified section is delineated by "BEGIN CHANGE"/"END CHANGE" comments.

The Korean keyboard has two keys that generate a single scan code when
pressed. The keys do n0t auto-repeat or generate a scan code on release. 
The scan codes are 0xf1 and 0xf2.

If it is one of the Korean keys, drop the previous scan code. If it is not, the earlier test to ignore auto-repeating keys would prevent 
this key from working two times consecutively. This occurs because the key does not generate a scan code on release.
