namespace EnvironmentPolicyDemo {
    internal static class Program {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main() {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            DevExpress.Data.Utils.EnvironmentPolicy.SuppressGettingEnvironmentVariables();
            Application.Run(new Form1());
        }
    }
}

VB.NET

Imports System
Imports System.Windows.Forms

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())
    End Sub
  End Module
End Namespace

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.
