需要安装MYSQL ODBC驱动程序.下载地址: Application Programming Interfaces (APIs) Official APIs: The C API is included with the server, above. Connector/ODBC - MySQL ODBC driver Connector/ODBC 3.52 -- development release Connector/ODBC 3.51 -- production release Connector/ODBC 2.50 -- old release //呵,我用的是这个,内有9X/NT版本的驱动 装成功以后,在ODBC数据源建一个MYSQL的ODBC(一般在最下面):输入ODBC名,用户,密码,数据库名等. 接下来就用这个ODBC进行联接就可以了.(当然你要先启动MYSQL)

1、显示密码
如：MySQL
连接远程数据库（192.168.5.116），端口“3306”，用户名为“root”，密码“123456”
C:/mysql -h
192.168.5.116 -P 3306 -u root -p123456
2、隐藏密码
如：MySQL 连接本地数据库，用户名为“root”
C:/mysql -h
localhost -u root -p
Enter password:
必须安装mysql的驱动才行，不管是vb还是c++都需要这个驱动。
代码如下：
public
function
exemysql(byval
sql
as
string)
as
adodb.recordset
sql
=
trim$(sql)
set
conn
=
new
adodb.connection
set
rs
=
new
adodb.recordset
conn.open
"driver=mysql
odbc
3.51
driver;"
_
"server=服务器地址;"
_
"port=3306;"
_
"database=数据库名;"
_
"uid=用户名;"
_
"pwd=密码"
conn.defaultdatabase
=
"数据库名"
conn.cursorlocation
=
aduseclient
set
rs.activeconnection
=
conn
rs.locktype
=
adlockbatchoptimistic
rs.cursortype
=
adopenkeyset
rs.open
sql
set
exesql
=
rs
set
rs
=
nothing
set
conn
=
nothing
end
function
楼上讲的是VB2005的连接方法，不知道你用的是什么版本的VB,我给你一个VB6.0的连接方法吧
先在本机上安装最新的ODBC CONNECTER/mysql
无需设置ODBC,就可以使用.
注意MYSQL的帐户登录是根据主机的,设置好MYSQL的帐户后再做测试.
测试代码:
Dim conn As ADODB.Connection
Dim rs As ADODB.Recordset
Dim fld As ADODB.Field
Dim sql As String
'connect to MySQL server using MySQL ODBC 3.51 Driver
Set conn = New ADODB.Connection
conn.ConnectionString = "DRIVER={MySQL ODBC 3.51 Driver};" _
"SERVER=192.168.0.1;" _
" DATABASE=db_name;" _
"UID=username;PWD=password; OPTION=3"
conn.Open
'create table
conn.Execute "DROP TABLE IF EXISTS my_ado"
conn.Execute "CREATE TABLE my_ado(id int not null primary key, name varchar(20)," _
"txt text, dt date, tm time, ts timestamp)"
'direct insert
conn.Execute "INSERT INTO my_ado(id,name,txt) values(1,100,'venu')"
conn.Execute "INSERT INTO my_ado(id,name,txt) values(2,200,'MySQL')"
conn.Execute "INSERT INTO my_ado(id,name,txt) values(3,300,'Delete')"
Set rs = New ADODB.Recordset
rs.CursorLocation = adUseServer
'fetch the initial table ..
rs.Open "SELECT * FROM my_ado", conn
Debug.Print rs.RecordCount
rs.MoveFirst
Debug.Print String(50, "-") "Initial my_ado Result Set " String(50, "-")
For Each fld In rs.Fields
Debug.Print fld.name,
Next
Debug.Print
Do Until rs.EOF
For Each fld In rs.Fields
Debug.Print fld.value,
Next
rs.MoveNext
Debug.Print
Loop
rs.Close
conn.Close
最简单的办法是：在VB里添加一个ADO部件，将其放到窗体中，然后右键选择属性，在其属性页的下面有个生成连接字符串的项，点击其后的按钮，然后一步步的来做（很简单的），然后连接字符串就会在那里生成，只要拷贝这个字符串，就可以用ADODB来连接了。。。
和SQL数据库差不多的，下面是我用vb6.0连接本地mysql数据库的连接字符串
"driver={MySQL ODBC 3.51 Driver};server=127.0.0.1;database=mysql;uid=root;pwd=sasa"
