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 ran the app. I guess the only real catch is that the product is in Beta test and won't be available to the general public until spring 2013. Still, it's going to be well worth the wait. I have a first round beta version of the product and have to admit, this is a solid product. So far I've see... (more)

Using the Tag Property – Part 1

Have you ever seen a form that has its own microhelp that changes when a field gets focus? I'm sure you have. You might see a window and at the bottom of the window is a line that says, "OPTIONAL - Enter the employee birth date," when a field is entered. We are going to create a simple automated solution that will allow you to carry the microhelp along in the DataWindow. Take a look at Figure 1. It's a freeform DataWindow with a SQL data source. I chose the Employee table from the sample database that comes with PowerBuilder. I didn't do anything special to it. My goal here is to ... (more)

Automating Formats and Edit Styles

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... (more)

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)

DataWindow Sorting with Column Headers

This article describes how to create a grid presentation window that allows sorting by clicking on the column header. To begin we need to create a grid DataWindow. I'm selecting just a few columns from the employee table. Here is my sql for the DataWindow in Figure 1. Once we have created it I get the DataWindow painter shown in Figure 2. There are several changes that we need to make. Let's change the status column so it's no longer a set of radio buttons. This is a read-only screen so let's remove the status and add a computed field. To do this let's remove the Status column ... (more)
