Has anyone also seen a problem when using CXTPWindowPos when changing DPI?

When e.g. running 100% DPI and using:

CXTPWindowPos().SaveWindowPos(this,_T("WindowPlacement"),_T("Dialogs\\MyDialog"));

and then when changing to 150% DPI and using:

CXTPWindowPos().LoadWindowPos(this,_T("WindowPlacement"),_T("Dialogs\\MyDialog"));

Then I see that the dialog size is the same, but the content cannot fit since it is scaled to 150% DPI.

Any good ideas to solve this problem generally?

My approach has been to append a DPI indicator to the lookup key (e.g. "WindowPlacement" becomes "WindowPlacement_192" for 200% scaling). So then you can either just track separate layouts (can't imagine users are changing DPI settings very often) or re-calculate and overwrite when you detect a change.

Thanks for the idea, I will use that. Actually you would be surprised how often this is reported as a problem.

By the way, now the CXTPWindowPos class can be handled, but what about the CXTPResizeDialog and CXTPResizePropertySheet using the CXTPResize class Load/SavePlacement, will they have the same problem? And are you handling these the same way?
