The Silver Coder on YouTube

[silvercoder70]

Hey y'all... been a little while! Uploaded a new video on handling date/time fields in queries and changing the display in grids. Here is the link -

I have finally added a playlist for Lazarus 4.0(RC1) and new videos in Lazarus will get added to the playlist "New Adventures in Lazarus 4.0".

Two videos out today/this evening...

(1) using lazbuild for compiling/linking (building) your projects from the command line - https://youtu.be/h1hzEQmGj1Y

(2) second video on dates with sqlite3 and strftime - https://youtu.be/QR2arjyb6YM

I have been trying to put a video out each day for lazarus and that is sort of working. Remember the videos are also part of the "A New Adventure in Lazarus 4.0" series.

If you like the videos and would like to see more of these, that is, more on databases and build tools, please let me know here, or in the comments of the videos. Happy coding everyone.

Part 2 on pointers is an example program that implements a linked list. Check it out here... https://youtu.be/Dy3ODz7kmmk

Happy programming!

As ideas for videos:

1. There is a topic that is practically not covered at all. And not all Pascal programmers bother with this. I'm talking about the topic of Unit testing. Using some simple example, let it be a calculator. What is needed for this and how to do it correctly.

2. Again, not a frequently discussed topic. Design patterns. There is not much information about them in the context of Pascal. But in video format there is simply no such content.

Thanks for the ideas... greatly appreciated!

Hey everyone,

Latest video is on conditional defines and link is here - https://youtu.be/KJwG4qOOTr0

As an aside ... noticed that HeapTrc unit does file I/O the "old" (if there is such a thing) way with Rewrite/Append etc. and so a video on file I/O makes sense. To me at least. What I am trying to do is lay the ground work in (modern) pascal before then going into OO related stuff and everything else in Lazarus. So, if you were/are hoping for the newer stuff, it is coming... slowly! But I feel the ground work before that is also important.

A second note ... I will also be switching from Windows to Linux (Mint) soon. Not sure what that means exactly for Delphi but there will obviously be more stuff from Lazarus. Of course, I could get something like Wine. So that is that part of where things are heading.

Finally, I will also be doing videos on patterns, testing frameworks in the near future as well.

Until next time ... Happy coding!

Next video is on file i/o - the old school way. Link is here ... https://youtu.be/Nj_Szf5DTEA

I've also moved to Linux now so there will be a lot more stuff with Lazarus. At least until I  get VM installed and given the other things I also do, that requires a break.

My one comment I will make, and as I made in the video, the speed of compilation and running of Lazarus in general, is superior for me compared to Windows. While I won't say how much faster it is, I will say it FLIES!

Compile speed difference was startling to me too (OpenSUSE). You may find, however, that linking in some situations can be a lot slower. YMMV.

In the adventure of Object/Modern Pascal, last night made our way into classes ... the introductory video about parts (fields, methods, etc) in a class. Here is the link - https://youtu.be/Ph0s0oF6RVU

[silvercoder70]

Two more parts have been added to series on Object Pascal

• Using Virtual Methods and Overrides in Modern Pascal. See https://youtu.be/dE5FVDrOhSY
• Classes - What is 'strict private'? Private not so private! See https://youtu.be/Qgbh-0gaR3Y

I have a video scheduled to come out tomorrow as a sneak peek into the videos you can expect to find (/view) in 2025. The link is - https://youtu.be/X_DJEyg5v94

Hoping that you all had a good 2024, and better 2025!

Maybe it would be better to make the written tutorials in a blog, at least that way I can translate them into my language with the translator, I can't watch the ones in video because I don't understand your language.
Also, if there were any updates or changes to be made to the tutorials, the ones that are written can be easily modified but the ones in video can't.

As a suggestion I could tell you to teach everything you can about modern pascal and lazarus, but above all teaching how to make useful programs: like a calculator, an agenda, a drawing editor, a notepad or even games, like pong, arkanoid, space invader. But always keep them as simple as possible so as not to overwhelm. Greetings

Hi Zelda, there are possibilities.  I normally speak off the cuff a bit. But from what you are saying,  if I had written text you would be able to convert into your language? Please confirm.  And if so, will see what I can work out.

Yes, I can, but Google Translate does it.

I am writing to you now thanks to the translator, I write in Spanish and then the translator translates it to English and I paste it here.

To read this page I just have to press the translate button that the Google Chrome browser has and I read it in Spanish. Any page that has programming content in English that interests me, I translate it with the browser and then I download it to have it as a reference.

But you have to keep one thing in mind, the text of the code has to be added in a bullet or something similar, because the browser, apart from translating the text, would also translate the text of the code.

Welcome to 2025 and here we are looking at ...

A guide to understanding and working with #exceptions in #Pascal (#Delphi, #FPC, etc.) programming, including handling multiple exceptions, re-raising, and creating custom exceptions.

Here is the link to the video ...

That's interesting.
Thank your for making the video.
