Namespace EnvironmentPolicyDemo
  Friend Module Program
    ''' <summary>
    ''' The main entry point for the application.
    ''' </summary>
    <STAThread>
    Sub Main()
      Application.EnableVisualStyles()
      Application.SetCompatibleTextRenderingDefault(False)
      DevExpress.Data.Utils.EnvironmentPolicy.SuppressGettingEnvironmentVariables()
      Application.Run(New Form1())

The EnvironmentPolicy fires the GettingVariable event when the DevExpress control attempts to retrieve the value of the environment variable from the current process. Handle the GettingVariable event to spot, analyze, and/or cancel the operation based on a specific condition.
