GetOpenFileName - два фильтра - VB

Формулировка задачи:

Использую api GetOpenFileName для вызова диалога выбора файла Как сделать один фильтр по двум расширениям? (*.GIF *.7z) Еще вопрос: есть ли подобный диалог выбора католога, а не файла Сейчас использую SHBrowseForFolder, что не очень удобно в плане использования юзером
