Need a solution for this

Hello, I am adding a new object to a list of objects like this.

Locations.Add(New Location)


How can I add the new object while its structure is filled out.
Here is the class

Public Class Location
Public ID As Integer
Public LName As String
Public LDesc As String
End Class

How can I have a Location filled out and added to a list instead of just creting a blank object.

I have to say, I really don't think you've thought about this very hard.

Dim loc As New Location
 
loc.ID = id
loc.LName = lName
loc.LDesc = ldesc
 
Locations.Add(loc)

You've almost certainly done the very same same thing in the past. It's just logical: create the object, populate its members, then add it to the list.

A couple more points to make.

1. That type should be a structure, not a class, unless you have some specific reason you need it to be a reference type.

2. Class or structure, if you'd used properties instead of fields then you could have used initialiser syntax:

Locations.Add(New Location With {.ID = id, .LName = lName, .LDesc = lDesc})

OK I have this solved now. I am uploading the source so it's easier to look at what I need help with.

In the program, I have the back forward and add running. I would like to implement an autonumber feature. right now, the location class has an ID field but its not being used. how can I implement an id field. here is what i am looking for.

It needs to auto increment. It has to skip ids that are already in the list.

This new questions has nothing to do with the old so it should have been asked in a new thread. One thread per topic and one topic per thread please.

Are you storing the data in a database? If so then you should let the database generate the IDs. Pretty much all databases provide that functionality, e.g. SQL Server allows you to make a column an identity, which will generate sequential IDs as data is inserted.
