Hi All,

I mean if you writing Sub Main in VB you can start you application either
way:

Dim mainfrm As Form1 = New Form1()
mainfrm.ShowDialog()

or just

Application.Run(New Form1())

What is advantage of each way? And how to count how many times user started
application and let do it only once? Looks like Shared property can't do it.

In this particular situation 'Application.Run' is semantically correct, but
'ShowDialog' isn't, because the form should not be shown as a dialog.

Dialog is model window other is modless.
if there are more than one gui forms/windows then it would effect.

Perhaps on Application.Exit and Start of app, manipulate this
information in some text file.
