salut,
j'essay de lire une base de données grace à un data reader et afficher le resultat dans des textbox mais je reçoi l'erreur suivante:
le code est le suivant :'System.Data.OleDb.OleDbDataReader.Friend Sub New(connection As System.Data.OleDb.OleDbConnection, command As System.Data.OleDb.OleDbCommand, depth As Integer, commandBehavior As System.Data.CommandBehavior)' is not accessible in this context because it is 'Friend'.
Code : Sélectionner tout - Visualiser dans une fenêtre à part
