I need some advice on the following code in the "Beginning VB.Net 2003" book:

On pg 159, in the 2nd grey block of code, the 6th line: Return lstCustomers.Items(lstCustomers.SelectedIndex)

When I type this in my code editor, it gives me the following error:

"Option Strict On disallows implicit conversions from System.Object to StructureDemo.Customer"

I have done exactly what the author has done & checked it again & again but it still gives me this error.

The same thing happens with the code given on pg 164, in the 1st grey block of code, line 4: Return Me.List.Item(Index)

Please can someone help me with this, I am new to programming and cannot figure it out myself.

Hi there.. You have option strict on. This means that you have to make any type conversion explicit to the system. You can't transform an object to another type (even if they are compatible) unless you specify what type is your destination (this is to avoid any type of conversion error). This is a common practice in languages like C# or even C++, but Vb always allow implicit conversions. You have 2 ways to solve this. First one, Turn off option strict (in the properties of the project). Second, make the conversions explicits: for example: I always prefer to keep option strict on and make the conversions myself, but you can do whatever you want..
