(Dave Ochs) Newsgroups: comp.windows.ms.programmer Subject: WM_PARENTNOTIFY message Message-ID: <36190001@hpcvra.cv.hp.com.> Date: 19 Feb 91 23:23:05 GMT Organization: Hewlett-Packard Co., Corvallis, OR, USA Lines: 11 Does anyone have experience with using the WM_PARENTNOTIFY message? It is purported to return the window handle and ID of the child window in lParam, but they don't look valid. Actually, they both *change* as I keep clicking the control. The control is a checkbox in a dialog box ... I am wanting to be informed when certain checkboxes are changed (immediatly). If you've got a hint, let me know. Dave Ochs Hewlett-Packard daveo@cv.hp.com
