can not fill dataset

[Palmtree]

The following is my code:
Dim sql As String = "Select * From tblStudnet"
Dim conString As String = "Driver={MySQL ODBC 3.51 Driver};SERVER=localhost;DATABASE=myDatabaseName"

'Create connection object
Dim connection As OdbcConnection = New OdbcConnection(conString)
connection.open()
msgbox"connected"

'Create data connection object
Dim daStudent As OdbcDataAdapter = New OdbcDataAdapter(sql, connection)

'Create a dataset object and fill with data using data adapter's Fill method
Dim dsStudent As DataSet = New DataSet()
dsStudent.Clear()
daStudent.Fill(dsStudent, "tblNewTable")

I got error at last line:

"An unhandled exception of type 'Microsoft.Data.Odbc.OdbcException' occurred in microsoft.data.odbc.dll

Additional information: System error."

Can you help?
