Вобщем-то у меня 2 вопроса:
1) Если вызвать функцию FlatSB_SetScrollProp Me.hWnd, WSB_PROP_VBKGCOLOR, vbBlue, False что бы сменить цвет фона ScrollBar'a на синий, то он почему-то меняется не на синий, а на какой-то его оттенок (кстати если задавать цвет функцией RGB эффект тот же самый) отсюда вопрос - как сделать так, что бы фон закрашивался цветом, который я передаю, а не его оттенком.
2) Можно вызвать функцию FlatSB_SetScrollProp Me.hWnd, WSB_PROP_PALETTE, тут что-то типа HPALETTE, False что бы ScrollBar при перерисовки использовал новую, указанную палитру. Вопрос: как эту палитру задать? (возможно, что решение этого вопроса автоматически дает ответ на первый)
