TBS_TOOLTIPS
Version 4.70. The trackbar control supports tooltips. When a trackbar control is created using this style, it automatically creates a default tooltip control that displays the slider's current position. You can change where the tooltips are displayed by using the TBM_SETTIPSIDE message.
TBS_REVERSED
Version 5.80.This style bit is used for "reversed" trackbars, where a smaller number indicates "higher" and a larger number indicates "lower." It has no effect on the control; it is simply a label that can be checked to determine whether a trackbar is normal or reversed.
TBS_DOWNISLEFT
By default, the trackbar control uses down equal to right and up equal to left. Use the TBS_DOWNISLEFT style to reverse the default, making down equal left and up equal right.
TBS_NOTIFYBEFOREMOVE
Version 6.00 and Windows Vista. Trackbar should notify parent before repositioning the slider due to user action (enables snapping).
TBS_TRANSPARENTBKGND
Version 6.00 and Windows Vista. Background is painted by the parent via the WM_PRINTCLIENT message.
