Private Sub btnSendMail_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSendMail.Click
Dim Message As String = "This is a test message to validate the email transmission

I am about to put my fist through my monitor!!! I have been working on this for the better part of 2 days. Here's the issue: I'm in an Enterprise environment and am writing an app that will shoot off small emails. I got the settings I needed yesterday and got everything to work 5 times in a row! Then, I went to another task for a little while and came back to the email portion and ran another test and it never worked again! I've written and re-written my code 100 times. I can't get it to work. Here's one version of my

I have written an application which uses the Outlook object library to send an e-mail with information from a textbox. I programmed this on Windows 7 and Office 2010, which was a mistake as most of the clients will be using Windows XP and Office 2007. I am getting an error when running the application on Windows XP/2007:
Could not load file or assembly 'Microsoft.Office.Interop.Outlook, Version=14.0.0.0 .... etc
I understand that this is because I have not loaded the Outlook 12.0 assemblies, however I am having trouble adding the assemblies on my Win7/2010 programming machine. I have downloaded the standalone Office 2007 PIAs however the Outlook 12.0 doesnt appear on the list, and when I try and add just the Office 12.0 I get an error.
is there a way to standardise and make the application work with both 2007 and 2010 outlook machines? I think it is possible, I have read some articles making the application choose the correct version, however cannot figure out how to.

I'm trying to populate class properties where one property is a list collection. I get a NullReferenceException when trying to add to the list collection. The code (litlle bit simplified) is here:
Public Class Portfolio
Property Name As String
Property Assets As List(Of Asset)
Public Sub Populate(ByVal data As DataTable)
For Each row As DataRow In data.Rows
[Code] .....
I have a nested class "Asset" inside the class "Portfolio". Everything goes ok until the line
Me.Assets.Add(asset)
Which gives me the NullReferenceException error.
