Push events from client to client

[MrDeej]

Hello!

I have a little trouble formulating the heading of this tread, but i will explain what my challenge is.

First of all, we are converting from Ms Access to Vistual Studio 2010 for our internal programs.

In that conversion we want to start with some of the basic functions we have created. One of which is a messaging system in the Access database.

The access messaging system works like this.
* All users have logon
* 2 tables are used, one of which puts a checkbox to -1 by the username to notifiy that it is a new message to you. The other table to store the messages
* We have a hidden form in the access database wich have a form_timer event that checks the first table every 10 seconds for value. If -1 then it opens some forms, play sound and so on


This is a solution which works fine, but creates a lot of data trafic when checking the table every 10 seconds for maybe 30 different user.

Is there a way to do this in Visual Basic.net (VS2010) that is better? Maybe even use push messaging in a way?

We are getting VS2010 installed tomorrow so we are very noobs here
