VFP 9 Cool Feature: Dockable Windows

As shown in the image below, the new dockable windows feature in Visual FoxPro can be a lot of fun. Forms now have a Dockable Property with the following values:
 
0 - Docking not permitted
1 - Supports Docking and Is Dockable
2 - Supports Docking but is NOT dockable
 
Huh? What does value 2 mean? It means that while the form will look like a dockable window, it cannot be docked. Users can make it dockable by right-mouse clicking on the title bar and choosing Dockable. They can also do this by selecting Dockable from the Window menu.
 
What does a dockable window look like? Essentially, it uses the half-height title bar property in VFP.
 
Having a dockable window also means your resize event better be smart. When a form is docked with another form, the resize method for BOTH forms is called. As well, if you dock two dockable forms at the top of the screen, the form that contains both docked forms now becomes a tabbed dialog with the tabs at the BOTTOM of the screen (i'll post an image).
 
Note: Dockable forms only work for applications that use the Visual FoxPro desktop. So if you are using top-level forms in your applications, be advised that the Dockable property won't work.
 
How will applications use dockable forms? At first glance, it really appears to be a feature that will be used heavily by framework apps and other tools that integrate directly into the FoxPro development environment, but there are certainly some types of applications where they will be handy. For example, in a number of my applications, we put a "message" or "alert" bar into the toolbar. The problem with this is that if the message uses an edit box, it screws up the entire toolbar height and width. With a dockable window, the alert message can now attach itself on the main screen to which it applies.

I was really looking forward to dockable forms in VFP. I had tried to build this feature into my forms earlier, but gave up.

I am very dissapoined though that the dockable feature only works for forms within the Visual FoxPro desktop. I wanted this for top-level forms, which is where I think it would actually be usefull. As it is, I don't see that I will ever use this feature, as I only build applications that run via top-level forms.

Elevating Project Specifications with Three Insightful ChatGPT Prompts

For developers and testers, ChatGPT, the freely accessible tool from OpenAI, is game-changing. If you want to learn a new programming language, ask for samples or have it convert your existing code. This can be done in Visual Studio Code (using GitHub CoPilot) or directly in the ChatGPT app or web site.  If you’re a tester, ChatGPT can write a test spec or actual test code (if you use Jest or Cypress) based on existing code, copied and pasted into the input area. But ChatGPT can be of huge value for analysts (whether system or business) who need to validate their needs. There’s often a disconnect between developers and analysts. Analysts complain that developers don’t build what they asked for or ask too many questions. Developers complain that analysts haven’t thought of obvious things. In these situations, ChatGPT can be a great intermediary. At its worst, it forces you to think about and then discount obvious issues. At best, it clarifies the needs into documented requirements. ...

Respect

Respect is something humans give to each other through personal connection. It’s the bond that forms when we recognize something—or someone—as significant, relatable, or worthy of care. This connection doesn’t have to be limited to people. There was an  article  recently that described the differing attitudes towards AI tools such as ChatGPT and Google Gemini (formerly Bard). Some people treat them like a standard search while others form a sort of personal relationship — being courteous, saying “please” and “thank you”. Occasionally, people share extra details unrelated to their question, like, ‘I’m going to a wedding. What flower goes well with a tuxedo?’ Does an AI “care” how you respond to it? Of course not — it reflects the patterns it’s trained on. Yet our interaction shapes how these tools evolve, and that influence is something we should take seriously. Most of us have all expressed frustration when an AI “hallucinates”. Real or not, the larger issue is that we have hi...

When A Machine Starts To Care

“Any sufficiently advanced technology is indistinguishable from magic.” Arthur C. Clarke (1962)  I first used that quote when I was starting out in the tech industry. Back then, it was a way to illustrate just how fast and powerful computers had become. Querying large datasets in seconds felt magical—at least to those who didn’t build them.  Today, we’re facing something even more extraordinary. Large Language Models (LLMs) can now carry on conversations that approach human-level fluency. Clarke’s quote applies again. And just as importantly, many researchers argue that LLMs meet—or at least brush up against—the criteria of the Turing Test.  We tend to criticize LLMs for their “hallucinations,” their sometimes-confident inaccuracies. But let’s be honest: we also complain when our friends misremember facts or recount things inaccurately. This doesn’t excuse LLMs—it simply highlights that the behavior isn’t entirely alien. In some ways, it mirrors our own cognitive limits....
