The critical part of getting this to work is to allocate the sub-dialog from within the main dialog class. In other words, the sub-dialog is created before it is needed. In response to a button push in the main dialog, the sub-dialog is then displayed. Button pushes and field changes within the sub-dialog can then illicit responses from methods defined within the sub-dialog's class. There is another example on this site which shows how to create a sub-dialog using the Pose() method. This works fine provided you only wish to capture the settings displayed within the sub-dialog. The method shown here is much more versatile, since it allows the full range of interactions between the user and both dialog and sub-dialog.
