我希望這段代碼能幫助你瞭解你在找什麼。

Private sub FillListBox 

    Dim stringConn As String 
    Dim stringCmd As String 
    Dim myConn As MySqlConnection 
    Dim myCmd As MySqlCommand 

    'Frame your query here. 
    stringCmd = "SELECT yourData FROM yourTable" 

    'Frame your connection string here. 
    stringConn = "SERVER=localhost;DATABASE=DBName;UID=root;PASSWORD=;" 

    'Get your connection here. 
    myConn = New MySqlConnection(stringConn) 

    'Get a command by using your connection and query. 
    myCmd = New MySqlCommand(stringCmd, myConn) 

    'Open the connection. 
    myConn.Open() 

    'create a reader to store the datum which will be returned from the DB 
    Dim myReader As MySqlDataReader 

    'Execute your query using .ExecuteReader() 
    myReader = myCmd.ExecuteReader() 

    'Reset your List box here. 
    ListBox1.items.clear() 

    While (myReader.Read()) 
      'Add the items from db one by one into the list box. 
     ListBox1.items.add(myReader.GetString(1)) 
    End While 

    'Close the reader and the connection. 
    myReader.Close() 
    myConn.Close() 

End Sub
