Using a combo box to store items in an array from a text file and then using that array and its components in another form - vb.net

Question

I'm currently designing an application within visual basic using vb.net. The first form asks for login information and then prompts the next form to select a customer. The customer information is stored in a text file that gets put in an array. I next have a form for the user to display and edit that information. How can I use the array I already created in the previous form in my display and edit form?
Private Sub frmCustomerList_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Dim sr As StreamReader = File.OpenText("customer.txt")
Dim strLine As String
Dim customerInfo() As String
Do While sr.Peek <> -1
strLine = sr.ReadLine
customerInfo = strLine.Split("|")
cboCustomers.Items.Add(customerInfo(0))
customerList(count) = strLine
count = count + 1
Loop
End Sub
Private Sub cboCustomers_SelectedIndexChanged(sender As Object, e As EventArgs) Handles cboCustomers.SelectedIndexChanged
Dim customerInfo() As String
Dim index As Integer = cboCustomers.SelectedIndex
Dim selectedCustomer As String = customerList(index)
customerInfo = selectedCustomer.Split("|")
End Sub

Answer 1

Make the next form require it in the constructor:
Public Class EditCustomer
Public Sub New(customerInfo As String())
InitializeComponent() 'This call is required, do not remove
'Yay! Now you have your info
End Sub
End Class
You'd call it by doing something like...
Dim editForm = New EditCustomerFrom(customerInfo)
editForm.Show()
Alternatively, you could have a property on the form you set.
Dim editForm = New EditCustomerFrom()
editForm.Customer = customerInfo
editForm.Show()
Then inside the Load event of that form, you'd write the logic that would display it looking at that property.
Aside: You should look at maybe defining an object to hold customer info and do some JSON or XML serialization for reading/writing to the file, IMO. This architecture is kind of not good as is....
