i understand your concerns, but new files will only be created when a new
user registers to replace the existing files with updated files. This will
not happen to often. For production i can add a lock to the files to solve
Its just for development, that new files will be created each time the page
Also, it is a question of resources. I do not want to draw points
dynamically each time i need a map.
It will be ok to draw the map from the files.
How to close the DBF and SHP files without the error i described?
I really do not know how to do that.
What i did is to open the dbf file with excel. All the data has been in
So i do not beliefe that this is the reason for not working. Somethine else
must be wrong.
Again my qustion:

I'm not sure about this, but I think you need to close the DBF and SHP
files that you create before you ask mapserver to display them.
Also this is not a good way to do this, because if you get two hits
close together the second hit will open the same file and try to write
data in it which my invalidate the file for the first hit.
You should look at the posts that came in today and yesterday? Subject
"Drawing features dynamically" which describes doing exactly what you
are trying to do.
