This is just a “fun” coding blog, but who knows, maybe you’ll find a good use for it on your projects 🙂 The goal is simple — move the control somewhere else — just like magic 🙂 Design (Setup) Super simple, just add the following to the default form: Command Button (to trigger the action) …
If you’ve been using Excel for a long time, you probably had written a macro or a VBA script. This blog isn’t about writing a VBA script, this blog would assume you already know how to. Instead, we’ll explore how and why to implement cache or caching in your VBA codes. What is caching? To …
You can easily research how to use a delegate, but most of the materials out there don’t really tell you the use-cases of these delegates, and so you don’t tend to use it. They give you a Hello-World-like example and you’re left to figure out how, when and why you’d implement it on your applications. …
There are many ways to do asynchronous programming in Python, but the one I’ll cover here is the probably the first option that most Python programmers will use, or is taught —- and that is using the threading module. Before we dive into coding, let’s talk about Synchronous and Asynchronous processing (or in our case, …
Pythons argparse module is very helpful when building command-line tools and so when I worked on Python 2.2 and couldn’t find it, I thought of creating one, a very lite version, for the most basic feature/functionality. It’s not a drop-in replacement, as I did not implement all the features and didn’t intend to — I …
This is a continuation blog. Please read Part 1 first, before reading this. Version 2: Component Based Let’s say that the data is no longer a dictionary or something that isn’t readily serialized by XML or JSON modules. For simplicity sake, let’s just create an object version of the data in part 1: Complex Data …

This will most likely be useful to you if you’re doing web applications (web services or web APIs) but the idea would still be applicable for other use cases. Since there’s really no standard way of rendering data, we usually have to support multiple format. In this blog, we’ll cover the most common formats in …

To most VB6 programmers, how the application behaves is based on how it was written — prior to compiling, that is. There’s just no way you can make it behave differently or dynamically once you compile it, right? Well, you’re right…. meaning, whether your VB6 code is dynamic or not depends on how you wrote …
Once upon a time, from a galaxy of long ago…. before dot Net, before the sockets, there was DDE… and it was good 🙂 Had to do that intro (LOL), this is a very old technology and very few VB6 programmers would even know this exist at all. You can Google what this is, but …
When you’ve been designing and writing systems for decades, you’d start seeing “patterns” in your own code, and if you’re lazy and smart, you’d either write a wrapper function to make multiple lines of code a single one …. or discover a built-in function that does exactly what you need. And this time it’s Python …
