There's a bunch of different ways to do this. The best method depends on the performance you want, the size of the file you want, whether you you that data to be editable outsire your app, how you're storing that data internally in your app, ... Dave Kreskowiak Microsoft MVP - Visual Basic

i am now storing every dot data item into MS-Access table fields. each dot data stored in each field. So it takes a long time when i am storing these dots. and when i read out the data. i have thought to store those data by string.But it is so much data that i can't find a data type field of Access datatable.

You could create your own dot structure, storing the points in a collection of them. You can then serialize that collection to either a binary file or XML. Binary would definately be smaller, but far less tolerant of changes to the structure. But, no matter what, since you're storing MILLIONS of points, it'll take a long time to do anything with them.
