Namespace EnvironmentPolicyDemo
  Friend Module Program
    ''' <summary>

    ''' </summary>
    <STAThread>
    Sub Main()
      Application.EnableVisualStyles()

      DevExpress.Data.Utils.EnvironmentPolicy.SuppressSettingEnvironmentVariables()

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