Люди, помогите, пожалуйста!
У меня проблема. Вот написал хорошенький текстовый редактор (хоть вместо Notepad'а ставь :) и позникла проблема: нужно в реестре найти значение параметра "(по умолчанию)".
Кто-нибудь знает как это сделать? Говорю (точнее, пишу) сразу: стандартных класс по работе с реестром из VB не подходит. Я в режиме отладки выяснил, что возникает ошибка и он вместо требуемого возвращает vbNullString (там, конечно, все схвачено с помощью On Error Goto ..."
