Close VB.Net application from Startup event

I am writing a vb.net application and am trying to close the application gracefully from the startup event if there are certain errors.

Is there a way to do this?

At the moment I have the "Enable Application Framework" checkbox selected, and all code is in the "Private Sub MyApplication_Startup(sender As Object, e As ApplicationServices.StartupEventArgs) Handles Me.Startup" event

The correct way to close during the Application.StartUp event is to set e.Cancel = True, since at that time there is no Form to Close nor a Application object to use Application.Exit

I changed my strategy and removed the "Enable Application Framework" and changed to my startup object to Sub Main()

A brief example is:

Sub Main(byval args() as string)

'Do my checking here
...


If MyCheckingFails then Return

Application.Run(MyMainForm)

End Sub
