For this project you will create 2 very small Visual Studio 2005 VB.Net applications demonstrating a specific interaction with a SQL Server 2005 Express database. You will also create an example database to use with the test apps.
First, create a SQL Server 2005 Express database with three tables. It does not matter what data is in there, and you only need a few fields and rows per table.
Second, create a VS2005 VB.NET app that inserts, deletes, or modifies records in the tables on a random time slot between 1 and 10 seconds.
Third, create a VS2005 VB.NET app that has three grid controls on it, looking at each of the database tables. Whenever one of the tables changes, refresh the corresponding grid to display the updated data, and also sound a BEEP. Polling the database on a time slot is not permitted, and direct communications between the two VB.NET applications is not permitted. The idea with the beep and grid refresh is that you are firing some event that I can add different code to later.
The objective is to create a mechanism so that the VB.NET app with the grids on it will automatically react to changes made to the database by the first application, without requiring communication between the two VB.NET applications, and without requiring polling.
I envision any change to a table raising an event in the second VB app that can trigger the grid refresh and beep, but remember, no direct communications between the two VB.NET apps.
Maybe you have to do something with triggers, service broker, or [login to view URL] integration. It should work fast and robust, and for multiple instances of the second application running (like 10 or 100, but you don't have to test at that scale, just keep in mind as you program this). Maybe notification services would work but I think I cannot use that with SQL Server 2005 right?
