We begin this article by asking the question: Why would you want to integrate real-time GPS data into your PowerBuilder applications anyway? After all, it's not likely you are going to connect a GPS receiver to your desktop computer and ask yourself where you are currently located. (At least I hope not!) More likely, you will be utilizing some sort of field service application where you need to know how to get from point A to point B, for example, an insurance assessor who needs to know how to get to the next accident site. For this, the user might use a tablet PC connected to a GPS receiver with some sort of integrated mapping solution. However, as PowerBuilder programmers, how are we to write such applications? Currently, unlike PocketBuilder, there is no built-in support for hardware devices such as GPS receivers. That being said, we will go about the task of "r... (more)

A Real-Time Physical Inventory Solution Using PocketBuilder, ASA, and a Wi-Fi Connection

Why do a physical inventory? A physical inventory count is necessary to reconcile the quantity on hand stored in a database versus what is really on the shelf. In a retail environment, this process is typically done once a year. In a perfect world, these values would always be in sync. The value would be decremented when items are sold and incremented when items are received. Unfortunately, this is not always the case. Consider shrinkage, shoplifting, and, my personal favorite, software bugs. Through a case study, this article will show how easy it is to architect a wireless real... (more)

Consuming Amazon Web Services Using PowerBuilder and SQL Anywhere 10.0.1

Since I'm in the middle of moving to a new city and need to get organized, I thought I'd roll a little application using SQL Anywhere, PowerBuilder, and Amazon Web Services to help organize my media collection. In doing so, I'm going to check out some cool features in SQL Anywhere, in particular, consuming Web Services. Calling Web Services out of your favorite development tool is nothing new. But who knew you could call them out of your favorite database? This opens up a whole world of programming fun. You might be wondering why you'd want to do this. Aside from the obvious - y... (more)

PowerBuilder 10.5 .NET Web Services Engine Has Arrived

Two things have my interest these days: the arrival of PB 10.5 and TechWave 2006! (Yes, that's right, I'm already planning ahead.) So, I thought I'd take this opportunity to roll a little application using MS MapPoint to illustrate what's new in PowerBuilder 10.5 Web services as well as help me plot my way from Chicago to Las Vegas for this year's conference! (see Figure 1). Sybase's introduction of the .NET Web services engine allows PB programmers to access Web services that have more complex data types than their EasySoap predecessor. This means we can use a rich array of servi... (more)

A Location Tracking System Using PowerBuilder, a GPS Receiver, and Microsoft MapPoint

Did you ever wonder where your kids are driving around on a Saturday night? Perhaps you are a business owner and need to know where your workforce is located on different job sites. With the help of PowerBuilder, a wireless connection, a GPS receiver, and Microsoft MapPoint, you can track the location of any individual in real-time. This article will show you how. To get things started you will need a few things: PowerBuilder A serial-based GPS receiver (Bluetooth will do) MS MapPoint 2004 MS Visual C# (for sockets implementation) A static IP address or a router capable of port f...
