get window handle of control

i have a form view with about a million controls on it! ;)

given one control's ID i want to be able to get the window handle of the control previous in the TAB order. Anyone know how?

Use 'GetDlgItem()' function to get the CWnd object of that particular control
Use 'GetNextDlgTabItem()' function to get the previous or next control in tab order.

****! how did i miss this function!

thanks for your help.
