This is a class library written in VB.net for connecting to MySql. You can use this class library to directly operate the MySql database.

  Before using this class library, you must install
ODBC MYSQL 3.51 download address: http://www.mysql.com/downloads/api-myodbc-3.51.html
Driver ODBC.NET download address: http:// www.microsoft.com/downloads/details.aspx?familyid=6ccd8427-1017-4F33-A062-D165078E32B1&DisplayLang=en

There are three categories in this library:
ManiPStringFormys QL: This kind of modified SGBD string
mysql_requettes: Send request
  MySQL_Utils: Test SGBD data

  The following is an example of using this kind of library to operate MySql

   //Operation on DataSet

  Public Shared Function MyODBCDataset(ByVal ReqSQL As String, _
                   As String, _
            ByVal Password As String, _
                ByVal NomDataSet As String) As DataSet
    ' Connexion à un server MySQL                                                                           using   using   using             using ‐ ‐ ‐ ‐ ‐‐ ‐ ‐                                    ing As String = _
        "DRIVER={MySQL ODBC 3.51 Driver};SERVER=" & Server _
                                                                                                 3;"

Dim MyODBCConnexion As New OdbcConnection(MyConString)
Try

Dim ds As New DataSet()

Dim cmd As OdbcDataAdapter = New
OdbcDataAdapter(ReqSQL, MyConString)
         Dim MyCommand As New OdbcCommand()
        Dim MyDataReader As OdbcDataReader
            cmd.Fill(ds, NomDataSet)
                                              use   using using ds to use                 through using ’ s ‐ ‐ ‐‐‐‐ ‐ to rite(MyOdbcException.ToString)
Catch MyException As Exception
'
HttpContext.Current. Response.Write(MyException.ToString)
End Try
End Function

//Call to function

Dim MonDatasetTemp As DataSet = MySQL_Requettes.MyODBCDataset(
SQL,
constantes.ODBCB ase,
            constantes.ODBCServer,

              constantes.ODBCPwd ,

            constantes.ODBCUser,

               "MonDataset")
