I implemented the SaveDockingState(regkey) function in a new PB2017 application to save the state of all docked / pinned windows and then use the LoadDockingState(), OpenSheetFromDockingState() & CommitDocking() functions to restore them. 

This functionality works fine for one or two windows open on exit. However, if a third window is open; the App closes;  and then reopens, only two of the three windows that were open are restored. This behavior is consistent and have not once seen all three windows restore on open.

Hi Steven;

  I have this feature working in my framework. You can see it in action in the latest (beta) example OrderEntry application which can be downloaded from here:  https://sourceforge.net/projects/stdfndclass/files/Applications/PowerBuilder/OrderEntry/Beta/PB2017R3

  The OE App can easily save & restore 4-8 dockable windows (tested - but, probably more). The framework creates the following registry entries (which is customizable) ...

  You can see the implementation code in the "wn_controller_master" object class's "oe_postopen" and "CloseQuery" events. The reason why the Dockable State is captured in the CloseQuery, is that this is the safe place to capture the open sheets. The framework has a "Sheet Manager" that closes all the open sheets (in reverse open order) before the Frame closes to make sure the App "shutdown" is smooth & orderly.

  When you run the OE app, just select the "Dockable" check box in the "login" dialogue to enter Dockable mode. Otherwise, it will run as a plain MDI frame based App. I still have some code "tweeks" to do but for the most part, its working well (for me).

  Here is an example start-up of the OE app that restores 5 dockable sheets ....


Regards ... Chris
