Hello,
I am implementing a timer as part of a chat functionality on my website with code I hand rolled. What it is supposed to is every 3 seconds it updates the members list so that after x amount of time it will remove members that are inactive from the list of who is in the room. It also updates the chat window for new messages posted by others. The Chat window is pulled out of a database for the last 100 messages. The database table is updated from a button when the user types it in one record per entry. Eventually I plan on purging the database table once a day to a file....
The situation I am having is as soon as I add the timer to do the updating, the retrieving of the chat window lines gets mixed up and not always placed in order of when inserted into the database, and sometimes it didnt even make it into the database... I have tried many routines trying to fix this over the past week but can not figure out what I am doing wrong....Help please
Here is my .ASP
