When do you call startupCheck?

    static void Main()<br />
    {<br />
      Application.EnableVisualStyles();<br />
      Application.SetCompatibleTextRenderingDefault(false);<br />
      Application.Run(new MainForm());<br />
      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^<br />
When debugging this is where the debugger goes after the call to Application.Exit()<br />
<br />
    }

bool startupCheckValue = true;<br />
// check for existence of necessary files and directories<br />
startupCheckValue = startupCheck();<br />
if (startupCheckValue == false)<br />
{<br />
  Application.Exit();<br />
}

private bool startupCheck()<br />
{<br />
  // make sure database file exists<br />
  bool dataBaseExists;<br />
  dataBaseExists = File.Exists(@".\Resources\myclub.mdb");<br />

    MessageBox.Show("The database file is missing from the Resource Directory.\nPlease install database file and start program again", "WARNING - CRUCIAL FILE MISSING", MessageBoxButtons.OK, MessageBoxIcon.Stop);<br />

I think the Application.Exit() is being called at the wrong place

static void Main()
{
  if (!startupCheck())
    return;

  Application.EnableVisualStyles();
  Application.SetCompatibleTextRenderingDefault(false);
  Application.Run(new MainForm());
}
