邮件已经发生，请查收。记得给分哈
首先你本地要安装MySQL Connector Net
工程引用mysql.data
连接数据库：
Imports MySql.Data
Imports MySql.Data.MySqlClient
‘连接字符串dbServerName 是ip,下面的英文应该懂得吧。
dim sA as string
sA = "server=" Me.dbServerName "; port=3306; database=" Me.dbDataBaseName _
"; user id=" Me.dbUserName "; password=" Me.dbPassWord "; "
dim mvardbConnectionMysql As MySqlConnection
With mvardbConnectionMysql
.ConnectionString = sA
.Open()
End With
4. 读取数据
dim xx As MySqlDataReader
Dim oC As MySqlCommand = New MySqlCommand(sSql, Me.mvardbConnectionMysql)
oC.CommandType = CommandType.Text
xx= oC.ExecuteReader()
if xx.HasRows
do while xx.read() ’一次读取一行
msgbox xx.item(2) '取出当前行的第三个字段的值显示。
loop
end if
5. 写入数据
Dim oT As MySqlTransaction = Me.mvardbConnectionMysql.BeginTransaction()
Try
Dim oC As MySqlCommand
'下面的commandtext是执行的更新语句，例如Insert into 语句。
oC = New MySqlCommand(CommandText, Me.mvardbConnectionMysql, oT)
oC.CommandType = CommandType.Text
oC.ExecuteNonQuery()
oT.Commit()
oC = Nothing
oT = Nothing
Catch oe As Exception
oT.Rollback()
End Try

1、VB.NET是一个高级程序设计语言
2、ACCESS是一个办公型的数据库
3、只要设置正确、代码完整是完全可以操作的
一般都是vb.net传入参数 交给存储过程去做的 你是要在vb.net前台就执行的例子 还是想要调用存储过程的例子
前台的一般就是这样
Dim paras As New NameValueCollection
paras .Append("delete from T_AlarmConfig ")
paras .Append(" where AlarmConfigID=@AlarmConfigID")
调用存储过程的就是给写存储过程了，这是调用存储过程的例子，只能理解理解
''' summary
