Help.

Hi, I have created a database with the backend of Mysql and i am accesing the database using PHP scripts. In the database there is one field, which has the information of the structure of a molecule as a Coordinate data. when i am using the mysql_fetch_array() command to retrive the data, it's just taking the text part of the file, which is simply a ASCII characters and displaying that on the browser screen. I have a program whihc will take that coordinate file as the input and it will convert that file into a 3D structure, i have the exe file of that program. Now my query is how do i access this exe file in the php script???, Is that Possible in some way??? so the data is retrived it has to automatically invoke the ./xxx file and it will give the 3D rendering of that data which is in the form of coordinate file. Please give me some suggestiosn about this. Thanks in advance. Raji __________________________________________________ Do You Yahoo!? Make international calls for as low as $.04/minute with Yahoo!
