.NET Shared Add-In for Outlook - calling another form in the proje

Good Afternoon,
I am working on a .NET Shared Add-in for Outlook. Currently, I have a
command button which when clicked executes the following code:
Imports CTXOutlookAddin.frmCTXNotesHistory

Dim frmCTXNotesHistory As New frmCTXNotesHistory
With frmCTXNotesHistory
frmCTXNotesHistory.Visible = True
End With
This form will display and update records from a SQL table. My issue is
that the Sub Main in the form frmCTXNotesHistory is not executed. My
question is am I calling the form incorrectly from Connect.vb? If so, what
is the correct syntax to properly call and display the form from Connect.vb
so the logic in the form will execute?
.
