In Part 1 we looked at the overall architecture of DataWindow.NET (PBDJ, Vol. 11, issue 4); in Part 2 we'll start coding our first application. We'll code a simple client application that contains two DataWindows with a master-detail relationship using the Department and Employee tables from the PowerBuilder 10 Demo Database (EAS Demo DB V10). For simplicity's sake, we'll provide the option to update only the employee salaries, but obviously the application could be easily extended to allow for inserting and deleting employees as well as departments. Creating the DataWindow Objects Begin by creating the master and detail DataWindow objects using either PowerBuilder or DataWindow Designer. The master DataWindow, d_department, retrieves from the Department table and has a simple select statement as its source. The detail DataWindow, d_employee, retrieves information ... (more)

IBM & Informix

In this article we'll discuss connectivity requirements, Informix-specific data type processing, and the use of Informix stored procedures within the PowerBuilder environment. PowerBuilder offers developers four specific connectivity options for IBM Informix databases: Third-party Open Database Connectivity (ODBC) drivers Third-party Java Database Connectivity (JDBC) drivers Third-party OLE-DB providers The "native" driver available in the PowerBuilder Enterprise version In this article we'll focus on the last option and in Part 2 we'll discuss TEXT and BYTE data, Stored Procedur...

The Debut of DataWindow.Net

Introduced in 1991 and patented in October 1996, PowerBuilder's DataWindow technology remains one of the most flexible, dynamic, and versatile means for data retrieval, modification, and presentation available in any development tool. By launching DataWindow.NET along with PowerBuilder 10 later this year, Sybase is continuing its commitment to the four-phased .NET strategy announced in 2002. DataWindow.NET is a separate product offering that brings PowerBuilder's hallmark technology to the growing number of programmers in Microsoft's.NET environment, including those using develo...

EAServer Problem Analysis & Troubleshooting

Designing and implementing an n-tier or Internet application is a complex task, and issues resulting from errors in the runtime configuration or in the application code are practically inevitable. Problem analysis and troubleshooting are part art and part science. Therefore, although the techniques we'll discuss are often helpful, the sheer diversity of client and server environments precludes a single recipe for resolving all issues. Part 1 (PBDJ, Vol. 12, issue 2) focused on problems that involve PowerBuilder and that occur from the point of connectivity all the way through an E... (more)
