SUMMARY
=======

This article provides information on how to display double-byte characters (for
example, Kanji, Chinese, Korean), that are written with a non-localized version
of Visual Basic and run on non-localized Windows NT.

MORE INFORMATION
================

The following steps and sample code demonstrate how to display Kanji characters.
Cp_932.nls, the Kanji character code page, and Msgothic.ttf, a TrueType font,
are required for this demonstration. This approach does not apply to Windows 95.
Windows 95 does not support TextOutW API.

NOTE: Cp_932.nls and Msgothic.ttf can be found in the Ielpkja.cab file included
with Internet Explorer version 5.01. For additional information, click the

  Q246073 Internet Explorer 5.01 File List (1 of 3)

Step 1: Register the Code Page File
-----------------------------------

1. Copy the code page file, cp_932.nls, into the \Windows\System directory.

2. Start the Registry Editor and locate the following: HKEY_LOCAL_MACHINE
  Subtree: \System\CurrentControlSet\Control\NLS\CodePage

3. If entry 932=cp_932.nls does not exist in the registry list, add a new value
  from the Edit menu:

Value Name: 932
     Data Type : REG_SZ
     String    : cp_932.nls

Step 2: Install Kanji Font
--------------------------

1. Open the Control Panel.

2. Double-click the Fonts icon.

3. On the File menu, click Install New Font to install Msgothic.ttf.

Step 3: Create the Visual Basic Application
-------------------------------------------

1. Start a new project in Visual Basic. Form1 is created by default.

2. On the Insert menu, click Module. The default is Module1.

3. Paste the following code into the General Declarations section of Module1:

     Declare Function TextOutU Lib "gdi32" Alias "TextOutW" _
                       (ByVal hdc As Long, ByVal nXStart As Long, _
                        ByVal nYStart As Long,  lpUnicode As Any, _
                        ByVal cbString As Long) As Long

     Declare Function SelectObject Lib "gdi32" (ByVal hdc As Long, _
                        ByVal hgdiObj As Long) As Long

     Declare Function CreateFontA Lib "gdi32"  (ByVal nHight As Long, _
                        ByVal nWidth As Long, ByVal nEscapement As Long, _
                        ByVal nOrientation As Long, _
                        ByVal fnWeight As Long, _
                        ByVal fdwItalic As Long, _
                        ByVal fdwU As Long, ByVal fdwS As Long, _
                        ByVal fdwChar As Long,ByVal fdwO As Long, _
                        ByVal fdwC As Long, ByVal fdwQ As Long, _
                        ByVal fdwP As Long, ByVal lpszFase As String) As Long

    Declare Function DeleteObject Lib "gdi32" (ByVal hObject As Long) As Long

    Type Unicode

             h As Byte
             l As Byte

    End Type

1. Add a command button (Command1) to Form1.

2. Paste the following code into the General Declarations section of Form1:

     Private Sub Command1_Click()

        Dim hFont As Long
        Dim hOldFont As Long

        hFont = CreateFontA(32, 16, 0, 0, 400, 0, 0, 0, 128, 3, 2, 1, 49, _
        "MS Gothic")
        hOldFont = SelectObject(Form1.hdc, hFont)

        Dim MyUniCode(3) As Unicode

        MyUniCode(0).h = CByte(140)
        MyUniCode(0).l = CByte(128)

        MyUniCode(1).h = CByte(140)
        MyUniCode(1).l = CByte(127)

        MyUniCode(2).h = 0
        MyUniCode(2).l = 0

        Dim di
        di = TextOutU(Form1.hdc, 100, 100, MyUniCode(0), 2)

        Call SelectObject(Form1.hdc, hOldFont)
        DeleteObject (hFont)

       End Sub
