vb连接mysql错误代码

引用Microsoft ActiveX Data Objects 2.8 Library
引用Microsoft ADO Data Control 6.0 (OLEDB)控件。
添加两个文本框，三个命令按钮，一个Adodc控件。

运行的话，应该会出现下面5个错误，错误语句的修改可以对比它上面的注释语句来修改。
1、编译错误:过程声明与同名事件或过程的描述不匹配
原因：Microsoft ActiveX Data Objects 2.8 Library与Microsoft ADO Data Control 6.0 (OLEDB)控件冲突。
解决办法：取消引用Microsoft ActiveX Data Objects 2.8 Library，改为引用Microsoft ActiveX Data Objects 2.0 Library

2、编译错误:未找到方法或数据成员。
原因：
解决办法：在过程Form_Load里，把“Text1.DataSource = Adodc1”改为“Set Text1.DataSource = Adodc1”。

3、[MysqL][ODBC 5.2(a) Driver][MysqLd-5.6.13]No database selected
原因：Adodc1.ConnectionString没有选择数据库
解决办法：在过程Form_Load里，为Adodc1.ConnectionString添加“;DATABASE=abc”。

4、点击删除数据库，提示实时错误 '3001':参数类型不正确，或不在可以接受的范围之内，或与其他参数冲突。
原因：Text1不等于Text1.Text。
解决办法：在过程Command3_Click里，把“m_rsPhone.Open Text1,...”改成“m_rsPhone.Open Text1.Text,...”。

5、文本框显示乱码。 原因：创建数据库的时候，没有选择字符集。 解决办法：先执行删除数据库。然后修改代码，在过程Form_Initialize里，为m_conPhone.Execute "create database..."添加“ character set gb2312”。
