Итак, я создал новый бэкэнд в Access, где я использую SQL Server, но я сохраняю бэкенд предыдущей базы данных в Access.Таблицы связаны с SQL Server, но все отчеты, запросы и формы связаны с моей предыдущей базой данных.У меня проблема с моим коммутатором в моем новом приложении.Я получаю сообщение об ошибке выше в названии этого вопроса, и когда я иду к его отладке, он выделяет эту строку: Me("Option" & rs![ItemNumber]).Visible = True, которая отличается от
If (rs.EOF) Then
Me![OptionLabel1].Caption = "There are no items for this switchboard page"
Else
While (Not (rs.EOF))
Me("Option" & rs![ItemNumber]).Visible = True
Me("OptionLabel" & rs![ItemNumber]).Visible = True
Me("OptionLabel" & rs![ItemNumber]).Caption = rs![ItemText]
rs.MoveNext
Wend
End If
Коммутатор устанавливаетфокус на Option1, а затем переходит к Option2, пока не достигнет числа conNumButtons, которое равно 3.
Я не знаю, почему он пытается найти Option0, когда он устанавливает фокус на Option1 особенно, когда в исходном приложении нет поля или метки с именем Option0 и, очевидно, в этом новом приложении нет ни одного поля с таким названием.Все в этом исходном приложении / базе данных в этом новом тоже самое, за исключением того, что таблицы связаны с SQL Server, а не с Access.Вот остаток моего кода:
