– AS/400 OLE DB Provider: OLE DB is part of Microsoft's universal data access
standard for 32-bit Windows users. OLE DB is defined as a multi-platform access
method for relational and non-relational data. Client Access provides an OLE DB
provider (driver) so any client/server application written to this interface can be used
to access AS/400 resources. The OLE DB provider can be used for record level, SQL
calls, data queues, remote commands, stored procedures, CL commands, and
distributed program calls. The AS/400 SDK for OLE DB and ActiveX, for use with the
AS/400 OLE DB provider, is provided as part of the Client Access Express Toolkit.
• ActiveX automation objects: Are designed for developing client/server applications
between the PC and the AS/400 system. Objects are provided for working with AS/400
systems using Client Access data queues, remote commands, and distributed
program calls. Many popular client languages, such as Visual Basic, Delphi,
PowerBuilder, and Visual C++, support ActiveX automation objects. Data manipulation
objects are also included to make it easy to handle code page conversions. Online
help (including example code) is provided and can be accessed from object browsers.
• PC5250: Enables programmers to add a PC interface to existing AS/400 applications.
PC5250 enablers include:
– Industry-standard emulation EHLLAPI enables programmers to add a graphical
interface to applications written to a 5250 interface to perform functions such as host
data access, screen scraping, and host automation. This 32-bit support also enables
applications currently written to the EHLLAPI of another emulation product to migrate
and run unchanged using PC5250.
– WinHLLAPI support is implemented so customers who have WOSA-compliant
applications can migrate to PC5250.
– PC5250 DDE includes code conversion support. This provides a more consistent set
of DDE APIs, which makes it easier to migrate applications across different platforms.
– Enhanced Non-Programmable Terminal User Interface (ENPTUI) provides 5250 data
stream functions such as ability to show radio buttons and check boxes on end-user
desktops that can support these functions (such as a PC versus a 5250 terminal).
Users have requested the ability to enable/disable this function in order to complete
certain actions. The PC5250 workstation profile enables ENPTUI to be turned on or
off.
– PC5250 ActiveX Controls have been added and can be used in any application that
supports ActiveX controls (such as Visual Basic and C++). These controls enable host
applications to use a list box or button.
• Recording can be done in Visual Basic (VB) scripts or a macro. A tool/utility is also
included that can convert a macro to VB Script.
• AS/400 Toolbox for Java: Includes a series of low-level APIs for accessing AS/400
data and resources from a Java program. It also includes a set of GUI classes to
