    - Database comparison tool
      A new application template, CompareDBs Reports (comparedbs.ntf), installed on the Domino 12.0.1 server, can be used to compare two database designs and/or document contents or to analyze the design of one database.
  - What new in Domino Designer 12.0?
    The following features are new in HCL Domino Designer 12.0.1.
- Accessibility and keyboard shortcuts
  Accessibility features assist users who have a disability, such as restricted mobility or limited vision, to use information technology content successfully.
- Application Design
  Welcome to the Application Design section of Domino® Designer Help.
- Application Management
  Welcome to the Application Management section of Domino® Designer Help.
- Domino® Query Language
  Domino® Query Language (DQL) is a facility running on a Domino server that provides a terse, shorthand syntax for finding documents. It supports a wide variety and complexity of search terms. It leverages existing design elements, avoiding the need to write detailed code to access them. DQL consolidates all methods in Domino for searching document contents.
- Composite Applications - Design and Management
  Composite applications are a key element in a service-oriented architecture (SOA) and contextual collaboration strategy. The ability to create and edit composite applications lets you easily integrate different types of components and technologies.
- DB2® Access views
  Domino® Designer includes two types of design elements to assist you in managing data contained in DB2® enabled Notes® databases:
- Programming Overview and User Interface
  This section contains general guidelines and examples that show where to use Java, LotusScript, and the formula language.
- Formula Language
  This section documents the formula language.
- LotusScript® Language
  Welcome to the LotusScript® Language section of Domino® Designer Help.
- LotusScript/COM/OLE Classes
- Java/CORBA Classes
  This section documents the Java/CORBA classes.
- Connectors
  Connectors provide native access to a wide variety of DBMS products, ODBC, the platform File system, Enterprise Resource Planning systems, and Transaction Processing systems.
- Javadoc™ for Domino® Designer related APIs
  As part of providing additional Java™ reference documentation, Domino® Designer ships with a help plugin that contains Javadoc™ for additional Domino Designer related APIs.

UseDoubleAsPointer method for Notes session class

This new method for the LotusScript Notes session class lets you use a Double to handle a 64-bit pointer argument for a C API call.

LotusScript does not have a pointer type so it can encounter issues when a LotusScript agent is used to call C API 64-bit pointers. The UseDoubleAsPointer method provides a workaround for this limitation by allowing a Double to handle a C API 64-bit pointer argument. Note that Long used to be used for pointers but is too small to carry a C pointer.

This workaround was previously available through the Domino notes.ini setting LS64BITCCALLOUTPointerSupport=1. However, the notes.ini approach had the downside of affecting all LotusScript agents on the server.

UseDoubleAsPointer requires a Domino Designer 12.0.1 client for the LotusScript coding and a Domino 12.0.1 server to run the LotusScript agent.

For more information, see UseDoubleAsPointer (NotesSession - LotusScript ).
