there is OnInitDialog but it intervenes only in the start and not always when dialog opens

You can only use the events that are listed. And OnInitDialog is called just before it opens.
Another link to the Microsoft documentation might also be helpful.
Using Dialog Boxes - Win32 apps | Microsoft Docs[^]

Since a dialog is derived from CWnd one could probably also use these messages. BeginPaint is probably also involved in displaying the dialog.
C
if ((hwndOwner = GetParent(hwndDlg)) == NULL) {
    hwndOwner = GetDesktopWindow(); 
    }
   
I recommend that you use the Spy utility and find out for yourself exactly what messages are sent. If you have never used it then this is a very good opportunity to learn how.
