I have successfully created a tooltip using TOOLINFO structure, and changed its time on, changed the title, changed the text, using SendMessage and the proper TTMs. However I do not want the tooltip to popup when over the control's Vscrollbar. I played around with TOOLINFO.rc values, but when I do, the tooltip won't pop up at all. What am I doing wrong?

.rc.right = listbox.width
.rc.left = listbox.left
.rc.top = listbox.top
.rc.bottom = listbox.height

.uflags = TTF_SUBCLASS



TTM_GETTEXTA = Wm_User + 11

Dim parentHwnd as long 'handle of the control I want the tooltip to trigger over
