Clearing cosmetic layers while saving valid map edits

[David Reid]

Greetings all,

I'm having a major malfunction this morning trying to wrap my head around
this task.

I have an mbx that has opened a couple mapper windows, and a couple browser
windows.

Either or both mapper windows may have "junk" in the cosmetic layer which I
know is safe to discard.

When I terminate this app, I wish to 'Close All' windows, discarding the
junk in the cosmetic layers, but saving any valid map edits if there are any
pending which I haven't noticed.

I thought I'd accomplish this with a "Commit All" type of statement, then
issue the "Close All" command without the "Interactive" statement... But
this approach seems a bit too simplistic... 'cause this dog just won't hunt!

Any help toward a solution would be greatly appreciated.

David,

Before terminating the app, could you include some code to clear the cosmetic layer? You'd just need to find the name of the cosmetic layer for each map window and then use RollBack Table:

For x=1 to NumWindows()
If WindowInfo(x, WIN_INFO_TYPE) = WIN_MAPPER Then
sCosName = WindowInfo(x, WIN_INFO_TABLE)
RollBack Table sCosName
end If
Next

You could also test to see if any tables had outstanding edits that need to be saved:

For x=1 to NumTables()
If TableInfo(x, TAB_INFO_EDITED) Then ' true so save edits
Commit Table TableInfo(x, TAB_INFO_NAME)
End If
Next

You can then issue a 'close all' knowing that any cosmetic layers are empty and all edits have been saved.

There's also an option under Options -> Preferences -> Map Window - Edit where you have 3 options to 'warn prior to loss of:', one of which is the cosmetic layer. If this is unchecked and you issue a 'close all', then any objects on the cosmetic layer will not be saved, though I'm not sure if you can check/uncheck this via MapBasic.

Greg! Thanks immensely! Works like a charm! (the Mapbasic scripting that
is). I didn't want to set the parameter in MI's Options>Preferences menu as
this for now is more-less a specialized in-house application, when not
running it, I may want to be prompted to save Cosmetic objects.

I utilized both functions, even though the "Close All" statement could work
as it causes MI to ignore cosmetic objects, "Close All Interactive" on the
other hand would prompt for saving cosmetic objects.

Thanks again!

David
