Top Stories by Richard (Rik) Brooks

I'm considering changing my emphasis in my column. Since speaking with some people at Sybase I am convinced that PowerBuilder is poised for a mighty comeback. The fact is that still today PowerBuilder is by far the most productive development tool available. It eclipses all the rest. An experienced PowerBuilder programmer is demonstrably more productive and can finish tasks faster than C# or even VB.NET. So why is .NET used by more companies? Mine would just be a guess and in fact, the answer is irrelevant. I'm here to tell you that Sybase is making an obvious push to regain some of the ground that it lost. The programmer who positions himself as a PowerBuilder expert today will benefit tomorrow. I am going to split my writing. This month I'll do another article on the classic DataWindow. That architecture is not going away. I've discovered that many companies are ... (more)

DataWindow Magic: Menu Security

Security is a must for most corporate applications. This article will give you a starting point to designing and implementing your own. We will do it with a table that is added to the example database and implement it in ancestor code. The idea is that you should only have to add rows to a table to implement your security. The Table The security table will provide a means to turn on and off controls and menu items as our inherited objects are constructed. Security Login_name varchar(20) PK Application varchar(20) PK Item_type varchar(10) PK Item_name varchar(20) PK Priviledge ... (more)

Appeon Developer Configuration

Have you ever used a datastore that ran without a problem while you were developing your application, but once you've compiled it stopped running? Let me tell you that's a difficult bug to fix. I remember it so well. I kept going back and forth. How in the world could the DataWindow work at design time yet not in the executable? I remember that I checked the return value of the datastore. I finally noticed that the datastore returned a -1. That's such a strange thing. The datastore returns the number of rows that were returned or a -1. The help files used to say that a -1 was in ...

The PostOpen Event – Why It Is So Important

Normally I try to write applications on the DataWindow or Appeon but every now and then I get a question that makes me sit back and say, "Huh?" In this case the question concerns the PostOpen event. I've seen that event named different things: ue_post_open, postOpen, post_open, ue_postOpen, etc. It has, as far as I can see, always had post and open in the name of the event. Further, just about every framework that I've ever seen has had that event in the base window. The question that I was asked was, "Why is that event there?" The programmer wanted to know why there was code in t... (more)

A Look at Appeon Mobile

The following article is an excerpt from Rik's upcoming book, ‘Mobile Application Development using PowerBuilder and Appeon' I am here to tell you it's true. You can write iPad applications in PowerBuilder. I'm sure that you are waiting for the other shoe to drop but ladies and gentlemen, there is no other shoe. It is simply the truth. You can write iPad applications in PowerBuilder. Those of you who have iPads, have you ever seen an MDI application running on an iPad? No? Neither had I. That is until I took a PowerBuilder application and, using Appeon, deployed to my iPad and ra... (more)
