A dynamic document template having static data, dynamic data, and/or procedural statements may be called by an application on a server. The dynamic document template is separate from the application program and is processed to form an interim script, which is then executed by a host computer system. The script generates document records in HTML or XML format that are output to a document. The data and procedural statements in the dynamic document template may be distinguished through interpreting mark-up language surrounding the data and procedural statements. The dynamic document templates execute in a separate namespace from the application and preserve the state of data in the application. A given application may call more than one dynamic document template to generate different portions of the output document. Additionally, the dynamic document templates may be replaced with new templates without affecting the application.

Scripted dynamic document generation using dynamic document template scripts

An apparatus for and method of efficiently accessing shared JavaScript objects within a multi-user environment by reducing the overhead required to maintain object/database property synchronization. A version is associated with each object to indicate whether any particular requested access is associated with the most current properties of the object. Each user has a version list which indicates whether any particular object properties need be updated before access. The version list is maintained in faster and more available memory than the actual object to enhance efficiency.

Method and apparatus for synchronizing dataset object properties with underlying database structures

An apparatus for and method of creating a standardized interface between Microsoft Component Object Model environment and a non-compatible legacy environment. The technique is equally effective for both object oriented and non-object oriented scripting protocols. The interface is scripted in the native legacy command language thereby freeing the interface developer from the need to create script in both the legacy command language and a Microsoft COM compatible language, such as Visual Basic. A determination is made upon an attempt to instantiate a COM server whether the server is local or in-process. If in-process and registered, the server is instantiated within a surrogate server to isolate the calling client from potential corruption of its memory space or copying of its sensitive data by the registered in-process server. This apparatus and method operates transparently to users and administrators, such that the client memory space and sensitive data is protected without requiring special COM server registration.

Method for protecting the program environment of a microsoft component object model (COM) client

An apparatus for and method of utilizing an Internet terminal coupled to the world wide web to interface with an existing proprietary data base management system through a user interface which permits access to an application service using a combination of proprietary language syntax and SGML-derived syntax. A specific code within the proprietary language is redefined to indicate that the immediately following script is in SGML-derived syntax.
