 The buddy will appear to the left of the trackbar if the trackbar control uses the TBS_HORZ style. If the trackbar uses the TBS_VERT style, the buddy appears above the trackbar control.
FALSE
 The buddy will appear to the right of the trackbar if the trackbar control uses the TBS_HORZ style. If the trackbar uses the TBS_VERT style, the buddy appears below the trackbar control.

lParam

Handle to the window that will be set as the trackbar control's buddy.

Return value

Returns the handle to the window that was previously assigned to the control at that location.
