Я создал модуль класса, но мой бэсик неможет понять основную массу строк и выдаёт об ошибке.

Если ты хочешь сохранять настройки своей программы, то достаточно использовать вот эти функции vb
GetSetting function - Retrieves registry settings.
SaveSetting statement - Saves or creates registry settings.
GetAllSettings function - Returns an array containing multiple registry settings.
DeleteSetting statement - Deletes registry settings.
Они позволяют использовать реестр в месте
HKEY_CURRENT_USER\Software\VB and VBA Program Settings\appname\section\key

Ну тогда попробуй разобрать пример от сюда: http://vbrussian.com/Files/registry.zip
там довольно хорошо все описанно.

Всё ясно как божий день мне не нужно было создовать модуль класса, а нужно было создать обыкновенный модуль с помошью которого я теперь могу добовлять что угодно. Но вопрос на засыпку если мне нужно сменить значение имя которого представленно (по умолчанию). я написал это в функции, но мне выдали об ошибке.
Да насчет getsetting . Это меня не волнует я знаю как сохранять параметры и форме, я хочу сам работать с реестром.
