Это моя первая программа на основе окон. У меня есть пять форм в моей программе, и в этих формах нет ошибок, кроме этого.Когда я пытаюсь запустить программу: (0xc0000005) Ошибка доступа к доступу
Я получаю сообщение об ошибке с этим ниже код:

Я отправил весь код. Я не знаю, что с этим не так. У меня такая же connString в моих всех формах, но это ошибка.
Возможно выполнить этот запрос из dbms? – Sachu
есть. ошибка - это не тот вопрос, который я предполагаю. debug говорит: "baglanti.Open();" на всей кодовой странице. –
были - это baglanti - это sqlconnection .. где r u устанавливает соединительную строку для того же самого? – Sachu
