At last, i found the answer myself. There is a item called
dwDrawStage in NMCUSTOMDRAW structure. If value of dwDrawStage
is equal to CDDS_PREERASE, call SetBkMode with transparent and
call SetTextColor. Then draw text with DrawText function. And
finally, return CDRF_NOTIFYPOSTPAINT. In short, do the color
changing process in pre-erase stage and return
CDRF_NOTIFYPOSTPAINT constant. As per MSDN, What this constant
means is,
>>> The control will notify the parent after painting an item.
>>> This occurs when the dwDrawStage of the NMCUSTOMDRAW
>>> structure equals CDDS_PREPAINT.
