Abstract: A method and apparatus for accessing information on a host computer 106 from a client computer 104 utilizing an intermediate server computer 108 that is connected to the client computer by a network. The host computer transmits a presentation space data stream representing a host screen to the server computer. The server computer creates an HTML document based on the information received from the host computer and transmits the HTML document to the client computer. The client computer creates a Web page based on the HTML document. The Web page includes fields and controls that implement the functionality of the host screens while presenting an improved user interface. A user can create HTML templates that substitute for the automatically created HTML documents for any one or more of the host screens.

Abstract: A method and apparatus for accessing information on a host computer (104) from a client computer (112) that are connected by a network. The information accessed by the client computer (112) is represented as a plurality of fields in a presentation space data stream (208). The fields and corresponding attribute information in the presentation space data stream (208), as received from the host computer (104), are extracted and stored in field objects contained within a Display control (202). A set of events is provided by the Display control to an application program (204), the events providing information to allow the application program (204) to manage the interaction between an operator and the host computer (104). A set of properties and methods provide the application program (204) with the ability to traverse the field objects and thereby obtain the field information sent from the host computer.

Abstract: A method for preserving the existence of a control during the lifetime of its container application is provided. A naming control is specified in an HTML document prior to specifying the target control. The naming control receives as a parameter a control identifier, which is passed to the class factory of the target control prior to creation of the target control. The class factory maintains a control list, with an entry for each control identifier corresponding to a currently active control. When a Web page is exited, the control is not deleted. Upon returning to the Web page and prior to creating a new control, the control list is checked to determine whether a control with a desired identifier is currently active. If so, a pointer to the corresponding control is returned, rather than create a new control.
