    Members
    MemberDescription
    UseCustom Use a custom setting (typically provided in a relevant "custom" property)
    UseDefault Use the application default setting
    Example
    Set GeneralOptions to Use Defaults
    //Default options can be set regardless of the value of the "companion"
    //path (to a project, folder, gdb, toolbox, etc.). The path value is ignored if
    //the option setting does not use it. This is the same behavior as on the Pro UI.
    ApplicationOptions.GeneralOptions.StartupOption = StartProjectMode.ShowStartPage;
    ApplicationOptions.GeneralOptions.HomeFolderOption = OptionSetting.UseDefault;
    ApplicationOptions.GeneralOptions.DefaultGeodatabaseOption = OptionSetting.UseDefault;
    ApplicationOptions.GeneralOptions.DefaultToolboxOption = OptionSetting.UseDefault;//set default option first
    
    //path values can (optionally) be set (back) to null if their 
    //"companion" option setting is the default option.
    if (ApplicationOptions.GeneralOptions.StartupOption != StartProjectMode.WithDefaultProject)
      ApplicationOptions.GeneralOptions.StartupProjectPath = null;
    if (ApplicationOptions.GeneralOptions.HomeFolderOption == OptionSetting.UseDefault)
      ApplicationOptions.GeneralOptions.CustomHomeFolder = null;
    if (ApplicationOptions.GeneralOptions.DefaultGeodatabaseOption == OptionSetting.UseDefault)
      ApplicationOptions.GeneralOptions.CustomDefaultGeodatabase = null;
    if (ApplicationOptions.GeneralOptions.DefaultToolboxOption == OptionSetting.UseDefault)
      ApplicationOptions.GeneralOptions.CustomDefaultToolbox = null;
