I have a Save-All-Modified dialog that displays a list view with a list of documents that have been modified. Currently it is sorted alphabetically by filename. I would like it to be sorted by the order of when the documents were last used. Basically it comes down to this:

I have two documents. I have to decide which one has a view that is higher in the z-order than the other ones views. Isn't there a windows routine to take to HWND and tell you which one is higher in the z-order?

Hi jhunt,

First there's no function to compare two windows by their z-order. It wouldn't be too hard to implement one using GetWindow() with flags GW_HWNDNEXT/GW_HWNDPREV, but I think it would be a better approach (better performance) to simply enumerate through all windows once using MDIGetActive() and GetWindow() with flags GW_HWNDNEXT/GW_HWNDPREV.

In the URL I provided you on the other task (with the 'Windows...' menu) you can find how to enumerate through the windows. You can use similar code to fill a list/array of document pointers to avoid duplicate occurances of documents in your list.

hope that helps,

ZOPPO

You can use the methods GetTopWindow() and GetNextWindow() to determine the z-order of your windows.

I think you can use the CWnd::SetWindowPos function.

According to the help doc, you can use the pWndInsertAfter parameter to indicate the previous window in the z-order.
To make this function ignore the (int x, int y, int cx, int cy) values, use SWP_NOMOVE|SWP_NOSIZE.
Example:
SetWindowPos(&wndTopMost,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE);

or

SetWindowPos(&MyPreviousWindow,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE);

I tried the GetTopWindow() and GetNextWindow()/GetPreviousWindow(). I also tried GetWindow(GW_CHILD) and GetWindow(GW_HWNDNEXT)/GW_HWNDPREVIOUS. Both of these didn't return any windows that were CFrameWnds. They only return CControlBar's, CToolbar's, CStatusBar's and CTempWnd's when using GW_HWNDNEXT and when using previous they returned NULL right away. Is there a window inside the mainframe that contains the child windows or something?

It should work if you start with:
(CWnd *) wnd = MDIGetActive();
and then call (in a loop):
wnd =  wnd->GetNextWindow();

Thanks ZOPPO,

I did figure it out in the end using GetActiveFrame().
