I'm looking for a way to keep the user visibility setting for a toolbar of my add-in after restarting Solidworks. I am using SetToolbarVisibility() and by that method I succeed to set the visibility of the toolbar for each document type, but what I would like to do is, is to preserve the visibility setting of the user after restart of Solidworks. I can see other add-ins doing this. What is the way to do this? Any help would be appreciated.
