Assigning Value To Property In Login Form

I've got a property in my class that I have given the task of holding the username of the person that logged in and I would want to access that username in another form another time. How do I go about this?

This is the code for my property:
Private _LogInUser As String = String.Empty
Public Property LogINUserName() As String
Get
Return _LogInUser
[Code] .....

This is how I am assigning my value to the property in my login form
'Private comm1 As CommManager = New CommManager' the new instance of the class
Dim sql As String = "SELECT reference,UserName,UserPassword,UserCompany FROM Users WHERE UserCompany = '" & cmbCompany.Text & "' "
Conn.Open()
Dim dt As DataTable = New DataTable
[Code] .....

How I expect to get my value
Label11.Text = comm1.LogINUserName
