EurekaLog options are represented by TEurekaModuleOptions class from EClasses unit. Each possible option is described in the description of EurekaLog Options dialog.

Option 1

Assuming you have EurekaLog's exception information object (e.g. inside event handler) - you can use .Options property:

{ ... } AExceptionInfo: TEurekaExceptionInfo; { ... }
 
AExceptionInfo.Options.SaveLogFile := False;

Option 2

Global options are returned by CurrentEurekaLogOptions function from EModules unit:

uses
  EModules; // for CurrentEurekaLogOptions
 
CurrentEurekaLogOptions.SaveLogFile := False;

Note: altering global options will not affect options of already raised exceptions. If you want to change options for a particular exception - obtain EurekaLog's exception information object for that exception and use .Options property (as shown in "option 1" above). E.g.:

uses
  EEvents;
 
procedure MyExceptionNotifyHandler(const ACustom: Pointer; 
  AExceptionInfo: TEurekaExceptionInfo; 
  var AHandle: Boolean; 
  var ACallNextHandler: Boolean);
begin
  CurrentEurekaLogOptions.SaveLogFile := False; // <- this is wrong!
  AExceptionInfo.Options.SaveLogFile := False;  // <- correct!
end;
 
initialization
  CurrentEurekaLogOptions.SaveLogFile := True; // <- correct!
  AExceptionInfo.Options.SaveLogFile := True;  // <- this is wrong!
 
  RegisterEventExceptionNotify(nil, MyExceptionNotifyHandler);
end.
