problem referencing a form

[Andy]

ok, I followed the direction for mimicking a global form from here:

http://msdn.microsoft.com/library/de...adingToNET.asp

I have followed the instructions to a 'T'. I created a Sub Main() in my module for my functions. I set the startup object to load sub main first.

in the sub main, I placed the code to instantiate the class just like the page said.

I get an error: object reference not set to an instance of an object
whn trying to manipulate a listview my calling it this way:

MainForm.Ticketing.tab_TrblHistory_lvwTroubleHistory.Items.Add(History(intCount).TicketNumber)


MainForm is the class, ticketing is the property and rest is the control I'm trying to add a row to.

What am I missing here?
