Exactly10 Videos ago we looked at a bug I found in Delphi related to visual styles, did it get fixed? Is it worth reporting bugs? Find out in this video.

Strings are special in many ways, and in this video, we take a look at how we can generate some strange behaviour when we return a string from a function. This behaviour is also exhibited by variants and dynamic arrays.

Want to return a value from a function? Normally you would use the "Result" keyword, but in fact, there is another way of doing it (and I'm not talking about Exit(Value)), watch to find out about this bit of obscure Pascal syntax - which may cause some hard to spot bugs if you are not aware of it.

As you may know, I've been writing a book, which is almost ready to publish. I want it to have page numbers in binary down the outside edge of each page, find out how I'm doing it in this video. Hint, I'm using Gnostice PDFToolkit - which I used my MVP superpowers to get a free license (by the power of Grayskull....).

In this video, we look at how we can omit string concatenation characters (+) when combining strings, plus adding Unicode characters to your application without using Unicode in your source.  Watch it on YouTube here.

In this video I do a quick experiment to demonstrate multiple forms in the same application with different styles - in fact, we will show all of the styles.  Per control styling is a new feature of Delphi 10.4 Sydney.

New in Delphi 10.4 is the Language Server Protocol (LSP), which replaces the backend for Code Insight / Error Insight - here are my first impressions.  Watch on YouTube.

Have you used ThreadVar before, never heard of it?  Find out about threadvar in this video!

In this (roughly produced) video, we have a first look at using the REST Debugger in Delphi to connect to Twitter, then build a very basic application in Delphi.  Watch it on YouTube.

The TIdHTTP component is great for downloading web pages and it has some powerful mechanisms for handling HTTP Redirects, we will look at the HandleRedirects property and OnRedirect event.  Find out how to use them in this video.
