Tooltips for own-drawn controls

[Semen Matusovski]

Chris & Patrice --
I draw some "controls" and using mousemove is able to detect a moment, when cursor is over this "control".
hWnd has only "parent".
Just now I will try to analyze suggestion about subclassing.
Thanks.

This is a cut and paste from WinLIFT

Semen;

I am not sure what you are asking for.

Are you trying to create your own custom Tooltips ?

Normal Tooltips controls should work for "any" type of control. They actually subclass themselves to any control they are attached to and work automatically, so why create your own ?

Folks --
I want to display tool tips for own-drawn (in WM_PAINT) elements.
I imagine how to do this by creating special class.
But probably exist more simple way, API similar DrawCaption, DrawFrameControl ?
