Background
This article aims to give an instruction on how to use Visual Studio to debug a C/C++ dynamic library that is called by a PowerBuilder 2019 application.
Here we will show you:
- How to create a C/C++ dynamic library.
- How to call this DLL in PowerBuilder application.
- How to debug the DLL called by the PowerBuilder application.
Description
Let’s take Visual Studio 2017 as an example to create a C/C++ dynamic library NewDLL.dll, which contains two functions:
- Add: Accepts two int parameters.
- ComputerName: Accepts a string parameter.
In addition, we will create a simple application with PowerBuilder 2019 to call this NewDLL.dll.

Given that not everyone is fluent in using Git and or Github (where the Open Source PFC is hosted now), I put together a quick introduction in how to get started. The video below walks through the steps, which in summary are:
- Create a GitHub account if you don't already have one. https://github.com/join
- Navigate to the Open Source PFC and "Fork" a copy of the code into your account. The 2019 version of the PFC can be found at: https://github.com/OpenSourcePFCLibraries/2019
- Chose Code -> Clone and copy the HTTPS URL for your fork.
- Open the PowerBuilder 2019 IDE and with no workspace open select File -> Connect to Workspace.
- Source Control System: Choose Git
- Repository URL: Paste in the URL you copied above
- Workspace File: Give it any name you choose
- User ID: Your Github user id (normally your email address)
- Password: Your Github password
- Checkout Directory: Select or create a new empty subdirectory on your local machine for the code to be copied to
- Wait until the source code is downloaded and refreshed (12 to 15 minutes)

The Resize service included in the PowerBuilder Foundation Class (PFC) framework is a powerful, yet easy-to-use tool in the developer’s toolbox. Due to several factors, however, many PB developers struggle to make the Resize service perform as they would like, particularly when the layout of window controls and/or the desired resizing behavior steps become non-trivial… and often the developer ends up getting frustrated. As a result, the desired functionality is frequently omitted or severely curtailed.
The issue is not that the Resize service is unable to perform the desired task(s) – I believe it can, in many (perhaps not all) cases. The real issue is learning how to effectively utilize the functionality that already exists. There admittedly is not a lot of instructional material available on how to use the PFC in general and the Resize service in particular, so I’ve created an easy-to-follow methodology you can use to make the Resize service do what you want instead of the Resize service making you to do what it wants.
As you’ll soon see, the steps I describe in this tutorial are simple, yet they can be quickly applied to complex resizing scenarios. I’m also going to give you some free code that implements a couple of handy resize-related features you may want to add to your projects.

Many PowerBuilder developers want to try Git as it gains in popularity. However, as PowerBuilder IDE still relies on the binary PBL format instead of directly working with the plain text source code files, the implementation of native Git support comes with some special features that you may need to be aware of in order to use Git properly or to work around some of the limitations. This article tries to give some tips in this area.

Symptom
When you push your repository from PowerBuilder IDE to your Git server for the first time after you do the Add to Source Control, it may fail when the size of your source code is large and/or your network is slow.
