Dear Experts,

As

• The following internal variable must be created in the Control Center:

• Example: "Background color" property of an object - authorization affecting the background color. If the authorization is granted, the background is green. If not, it is red.
  #include "apdefap.h"
  long _main(char* lpszPictureName, char* lpszObjectName, char* lpszPropertyName)
  {
  ///////////////////////////////////////////////////////
  // Query whether logged-on user has authorization level 4
  //
  if (PASSCheckAreaLevelPermission("@CurrentUser",4))
  return CO_GREEN;
  else
  return CO_RED;
  }
