I would like to use a WM_NOTIFY function to manage a slider thumb position change, according this MSN trackbar link TRBN_THUMBPOSCHANGING . Does somebody know why the notification code "TRBN_THUMBPOSCHANGING" for the slider control seems ignored in "WindowsConstants.au3" include file ? Searching in AutoIt or MSN forum , or googling this code, I don't succeed to catch any code info !!! Is it obsolete ? Thanks Alain.
