TBM_SETTICFREQ 
    wParam = (WPARAM) wFreq; 
    lParam = (LPARAM) 0;

Sets the interval frequency for tick marks in a trackbar. For example, if the frequency is set to two, a tick mark is displayed for every other increment in the trackbar's range. The default setting for the frequency is one; that is, every increment in the range is associated with a tick mark.

wFreq
Frequency of the tick marks.

The trackbar must have the TBS_AUTOTICKS style to use this message.
