my new beta GIS Software ElshayalSmart for map and data base editing and drawing

[Mr. Mohamed Elshayal]

Dear Andrew

Thank you for your reply

When I start building this software, I was drawing the map directly from 
files without loading it into memory
It was not very slow, but it was very complicated , so I ignored this 
solution.

I believe I will reconsider this solution again

I used Loading into memory to get the advantage of discarding all changes 
without saving them to disk
but, I have solved this problem in table files, by using tmp files for 
saving or discarding changes

Table data changes by editing or by VB script code will be saved into tmp 
files until you save it

I am still working in "Undo function" and viewing raster images

Thank you and best personal regards
Mohamed Elshayal
