Description:
Using VB.NET 2003
Hello,
I can use the 3.51 ODBC driver to connect to all of the databases mentioned below to the Linux/MySQL without any issues.
Tried on the following versions of MySQL linux
Server version 4.0.25-standard
Server version 4.1.7
Server version 4.1.18
With the connector/net I cannot even open the connection to the database I get the following:
First Error:
An unhandled exception of type 'System.Net.Sockets.SocketException' occurred in system.dll
Additional information: An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full
Second Error:
An unhandled exception of type 'System.TypeInitializationException' occurred in system.dll
Additional information: The type initializer for "System.Net.Sockets.Socket" threw an exception.
Final Error:
MySql.Data.MySqlClient.MySqlException: Unable to connect to any of the specified MySQL hosts ---> System.TypeInitializationException: The type initializer for "System.Net.Dns" threw an exception. ---> System.TypeInitializationException: The type initializer for "System.Net.Sockets.Socket" threw an exception. ---> System.Net.Sockets.SocketException: An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full

How to repeat:
This does work:
Imports System.Data.Odbc
Public ODBCConn As OdbcConnection
ODBCConn = New OdbcConnection
ODBCConn.ConnectionString = "DRIVER={MySQL ODBC 3.51 Driver};" & _
"Server=" & DBServer & ";" & _
"Port=" & DBPort & ";" & _
"Option=3;" & _
"Stmt=;" & _
"Database=" & DBName & ";" & _
"Uid=" & DBLogin & ";" & _
"Pwd=" & DBPassword & ""
ODBCConn.Open()
This does not work:
Imports MySql.Data.MySqlClient
Public MySQLConn As MySqlConnection
MySQLConn = New MySqlConnection
MySQLConn.ConnectionString = "server=" & DBServer & ";" & _
"uid=" & DBLogin & ";" & _
"pwd=" & DBPassword & ";" & _
"database=" & DBName & ";"
'Here is where I get the error
MySQLConn.Open()
