Hi - thanx for yours answers...

"Why is the parent of your child window not the view but its frame window? Or by saying view's frame you don't mean the frame but the view window?"

- i thought 'bout view not frame - sorry for my mistake...

i've added to my view class:

BOOL CCountersView::PreCreateWindow(CREATESTRUCT& cs) {
cs.style |= WS_CLIPCHILDREN;
return __super::PreCreateWindow(cs);
}

AND IT'S WORKING !!!

Thank you guys
