Imagine creating a DropDownDataWindow look and feel using HTML form elements that can show more than one column in a ListBox on a Web page.

This look and feel is similar to the JTable class of Java or the DB grid control in Visual Basic. In this article I'll demonstrate how to show an HTML element dynamically, depending on the user's action on a Web page. This code works both in Internet Explorer and Netscape browsers that support JavaScript and HTML 4.0. Need for DropDownDataWindows For Windows-based client/server applications, PowerBuilder has a neat feature called the DropDownData-Window that shows the multiple attributes of the data element. For example, in my current project I need to show an ent... (more)

It has become standard for stand-alone and client/server applications to contain Web browsers. A perfect example is Intuit's popular Quicken program. Quicken has the normal look and feel of a stand-alone application, but the startup sheet is a Web browser that presents up-to-the-minute Intuit information to the user. You too can build this functionality into your PowerBuilder application. In this article I'll describe how to use... (more)

Talking to PowerBuilder

Imagine creating a PowerBuilder application that not only speaks to the user, but also understands when the user speaks to it. Speech recognition software has been around for a while, but so far it's found only limited to success in real-world use. However, some of the latest advances in speech recognition make this form of input a viable option for business applications. In this article I'll describe how to use Microsoft Agent ActiveX technology to add speech and speech recognition to PB applications. About Microsoft Agent Version 2.0 Microsoft Agent is a royalty-free ActiveX t... (more)
