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%1, click the article number%2 below to view the article%2 in the Microsoft Knowledge Base:

246073 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
