Capturing WM_ACTIVATE in CPropertyPage

[jhwurmbach]

Does handling WM_SETFOCUS / WM_KILLFOCUS help you? (For me, it does not, because the controls get no WM_KILLFOCUS when the user clicks a Toolbar-button - probably the button does not accept the focus)

No, these messages are not sent to propery pages. MCP, MCSD

Well, I've tried capturing WM_KILLFOCUS and it doesn't reach the CPropertySheet :confused: That's the original problem I have - normal messages are eaten up by the CMainFrame and never reach anywhere. That's why WM_ACTIVATE doesn't work as well... MCP, MCSD

WM_KILLFOCUS does indeed reach a PropSheet. I do handle it there. If CFormView really eats it, re-send it in your CFormView derived class.

Well, WM_KILLFOCUS is caught in the CFormView, but I have no way of knowing (or at least I don't know of a way) to determine which window lost the focus, so I don't know to which window to send it. I have a property sheet and a grid control on my CFormView, and I need to determine when the property sheet looses focus, but OnKillFocus() provides a pointer to the new window, not the window that lost focus. Or is there a way to find out which window lost focus? Thanks for your help! MCP, MCSD

Well, now I am out of luck. You *could* try to call CWnd::GetFocus() to determine which control currently has the focus. But I do not know if this works. Sorry, without CFormView your sheet can catch WM_KILLFOCUS, and that is what I do. My only problem is that clicking a toolbar-button does not remove the keyboard focus from the control on my property page.

Yes, without the CFormView things worked for me too. That's why I got stuck when I implemented the CFormView. Perhaps it's an MFC bug or something... I think I'll go complain to MS, although that probably won't help me ;) MCP, MCSD

At least it won't be lost then. Thanks again for your help! MCP, MCSD
