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:

1. Set the Correct Character Set in the Database

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:

2. Configure ADODB to Handle Unicode

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:

3. Setting the Locale in VB6

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:

4. Ensure Font Support

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.

5. ADODB Recordset Handling

After configuring the connection and locale, make sure you're retrieving and displaying the data correctly:

6. Consider Using Unicode

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.

Troubleshooting

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.
