Hola
acse lo que te falta es enlazar tu
SqlCommand con la conexion :
Código vb.net:
Ver originalPublic Sub okcancelar()
Dim cnn As New SqlConnection
Dim cmd As New SqlCommand
cnn.ConnectionString = Me.conn.ConnectionString
'TE FALTA ENLAZAR CON LA CONEXION
cmd.Connection = cnn
cnn.Open()
'cmd = cnn.CreateCommand()
cmd.CommandText = ("UPDATE c_albven SET libre_1 = 'Ok.' WHERE letra = 'CC'")
cmd.CommandText = ("UPDATE c_albven SET libre_1 = 'Ok.' WHERE letra = 'CB'")
cmd.CommandText = ("UPDATE c_albven SET libre_1 = 'Ok.' WHERE letra = 'CA'")
MessageBox.Show("No Actualizas")
Me.RichTextBox1.Text = " Facturas Canceladas en Ok."
cmd.ExecuteNonQuery()
cnn.Dispose()
End Sub
Saludos!
