When using VB6 (Visual Basic 6) with ADODB Recordsets to display Chinese characters, it is common for the characters to appear as garbled text (like ??????
or ñ’è
). This typically happens because the proper character encoding is not being used or handled correctly. Here's how you can address this issue:
Ensure that your database is configured to store Chinese characters using an encoding like UTF-8 or GB2312. If the database is using a different encoding, you will need to either:
In VB6, ADODB's Recordset may not handle Unicode data properly unless the correct character set is specified. Here are the steps to ensure proper handling:
Connection
object's Charset
property to specify the correct character encoding.
For example, if you're connecting to a MySQL database, you would set the charset to UTF-8:
conn.ConnectionString = "Provider=MSDASQL;DSN=your_dsn;Charset=UTF-8"
For SQL Server, ensure that the column data type supports Unicode (NVARCHAR
instead of VARCHAR
).If your data comes from a text source (e.g., a file or external service), ensure that the locale in VB6 is set to support Chinese characters:
SetLocale
to configure the correct locale if you're working with Chinese text data in your application.
SetLocale "zh-CN" ' Simplified Chinese locale
Make sure that the font you're using in the VB6 form or control supports Chinese characters. Common fonts like SimSun or Microsoft YaHei should display Chinese characters correctly.
After configuring the connection and locale, make sure you're retrieving and displaying the data correctly:
GetString
method of the Recordset object to retrieve data as a string:
strData = rs.GetString(adClipString)
If your application needs to support a wide range of characters, consider upgrading to VB.NET where Unicode support is native, or use a third-party library to handle encoding conversions.
By ensuring proper character encoding at both the database level and within your VB6 application, you should be able to display Chinese characters correctly in ADODB Recordsets.
