Set Focus On Mouse Hover (MFC)

[TBBW]

Hello.

made a bitmap button (3 states up down and focus)
default is up.
using tab I can focus on the button.
disabled TAB,
I want to focus on mouse over or on mouse hover.

why does the following not work?

void C_MAINMENU_DIALOG::OnMouseHover(UINT nFlags, CPoint point)
{
	btnBmpCOD1.SetBitmap(::LoadBitmap(NULL, MAKEINTRESOURCE(IDB_COD1_FOCUS)));

		// TODO: Add your message handler code here and/or call default

	// CDialog::OnMouseHover(nFlags, point);
}

regards
