Given the following stored in the user's config file for a program,
just what is saved and restored using Settings.Write and .Read? This is
An example of what I am not seeing is if the user sorts the grid using
say column 3 descending, I don't see that saved in the config file
after a Settings.Write(gvwCard).
And by the way, just to make this a little bit harder. Consider a main
form that has an arbitrary number of other form controls homed in a set
of tabs, each "embedded" form being an
instance of one form class. I'll try and make this clearer. fMain has
a tabstrip where the number of tabs is set dynamically. Each tab
contains an instance of fEvent. The tabs are created
at startup with its Count set to the number of events happening today.
For each tab an instance of fEvent is created and parented in the
Now, it is possible that the user adjusts the column widths and sort
orders or even the font for the grid in each tab differently. So, when
the main form is closed (and closes each fEvent which issues a
is the settings that are saved determinate somehow? I have never been
