I'm a retired software developer. I developed and maintained a commercial ICCBBA ISBT-128 compliant blood product labeling application for decades. This channel will hopefully provide some insights into the development of graphical user applications for Linux and MS Windows using the Lazarus integrated development environment (IDE) and the Free Pascal Compiler (FPC). If you find the content of this channel of value please do me a big favor and "LIKE" and "SUBSCRIBE". Thank you.
Linux/MS-Windows Application Development using Lazarus/Free Pascal - Part 18
We wrap-up the Administrative User Password (Add, Change, Delete) functionality and User's ability to change their own password. Made changes to the way these things work, again. Discuss briefly future direction of this development. Cover documentation resources for the Lazarus IDE and Free Pascal compiler. The current code for the project can be found at this Google Drive Link (drive.google.com/file/d/1djYSflqhxZJ-fL3fm0R1zcOO9GUZq2rd/view?usp=drive_link). Thank you for liking, subscribing and commenting.

We completed the little bit of code for the User - Change window. We created the User - Delete window and got all of its code connected and working. The current code as of Dec. 13th 2024 can be access from this Google Drive link (drive.google.com/file/d/1w0-7cQtqraQXTY9k xM3sO_rD502oSm/view?usp=drive_link).

We complete the development of the Users - Change window allowing application administrator to make changes to the User ID and password of a user or administrator. The Goodle Drive link to the latest source code files is (drive.google.com/file/d/1l_G_aSBajn9QarJdTyRrWdnBmstHJbFV/view?usp=drive_link).

We continue to work on the User - Change window by allowing user name selection form the list box and populating the edit boxes when the "Select" button is clicked. Google Drive link to the application source files as of Nov. 29th 2024 (drive.google.com/file/d/168kF-HjWnbK8W1RgU1ILz4BkLMQw1ZnG/view?usp=drive_link).

Finish developing the User add window, change the Log On window, now differentiate between users based on access code. We create an administrator and test his access to restricted functions. Google Drive link to the files as of 2024-11-15 (drive.google.com/file/d/19dnWoPhQtciFC21X29D1YEtJstfiuB0T/view?usp=drive_link)

Project source code archive is available on Google Drive link (drive.google.com/file/d/1Cht3kg3_6rmzCcTVvfCvNFy6Pf254nZF/view?usp=drive_link). We correct a few issues with the uRFileIO unit. We add logic to the UnitLogOn code to now use the Users.dat file to verify the user. We correct the TUsrRec record type to fully record the MD5 hash. We test Log On functionality.

I announce that the project files are available on Google Drive via the link (drive.google.com/file/d/1xM21VzLAh_6wbeGTdq8VYdVRoHapZK5u/view?usp=drive_link) We build a new user password record and use the MD5 hash to hide the actual password. Make needed corrections to thhe uRFileIO unit. I struggle with several issues, but we get more done and working.

We create an include file that defines the User record type. We write a new unit that provides random file input / output functions that will be generically used throughout the application. We test compile and correct fat finger entry errors.

We add a new unit with a password evaluator to test for compliance with password rules and to provide helpful messages.

We modify hint options in the Lazarus development interface. We add a "Users" selection item in the Main Application menu. We create a new form and unit to provide for adding a new user. We connect the new form and unit to the Users - Add menu selection.

We add a Set Path function to the main application window. We create a new form that allows us to choose the target directory path for the application. We connect the new Set Path form to the Set Path menu selection of the main application form. We change the log on window to uses an initialization file to obtain the target application path for the application.

In this video we fix an issue with the UserID text entry box not receiving focus after a failed log on. We eliminate the need to use compile time directives to set the FileSep identifier to the appropriate OS directory/file name separator. We test the reading of the "MyApplicationFilePath.dat" file contents and modify the log on validation code.

There are a few code changes explained. Simple debugging methods are demonstrated. We set "breakpoints" to puase execution and "watches" to monitor the content of variables during application execution.

Installing Lazarus IDE and the Free Pascal Compiler on Linux - Getting Started
[ Senior Dev : me ] Maximun respect to [ Master Dev : Larry ], actualy i use free pascal TUI and Lazarus o'Pascal. I would like more information about the free pascal and lazarus package manager, if they exist! I would like to contribute to some facilitating libraries.
For detailed information you should try the URLs freepascal.org and lazarus-ide.org for the free pascal compiler and the Lazarus IDE documents. Each site offers search capabilities. I hope this helps. Thank you for commenting. 🙂
@@larrycullen9117 thanks
❤❤🎉🎉
Thank you.
Thanks for sharing. but sorry, your voice is too low.
I agree. Getting the level set on the dynamic microphone that I use has been and continues to be challenging. I'll try to do better next time. Thank you.
Nice video 👍
Thanks 👍
Didn't know you're an ESET fan :D nice glowing eyes android tho
Found that cool image years ago. I gave it red glowing eyes and made it my desktop image.🙂
I also like to use the IDE option to ‘Hide IDE windows on run’ in the Tools | Options Dialog.
I usually do the same as well. Just didn't do it with this fresh install.
I find that when you create a new Application, first do a save and save the first unit as mainform then save the project1.lpr as the Application name, eg. MyApplication. Also edit any forms or units in the property fields rather than the editor headings. We all learnt some good lessons here and creating the new application and saving it in correct order is important. I also like to regularly compile and check errors that way. I also like to format the code using Ctrl D. Thanks Larry great job, let’s get Lazarus Free Pascal easy to learn and use.
Good tips and explanations, Lazarus is great for developing GUI apps for Linux.
It really is!
I do like the default editor colour scheme for watching the videos, easy to read the code.
Hi Larry, I also like to develop applications using Lazarus and Free Pascal. I primarily use Arch base Linux and for installing I find the easiest method is to use the following command line in the users terminal. $ sudo pacman -S lazarus lazarus-qt6 this will install the latest versions, from the Arch Extra repository, lazarus-gtk2, lazarus-gtk3, lazarus-qt5 is also supported. Keep up the great work. Peter Walker
Thanks for the comment. I liked the Lazarus IDE and Free Pascal so much that I gave them a one time donation. I wrote code using Delphi from Embarcadero Technologies for over 20 years. It made life so easy.
I agree that Lazarus/Free Pascal offers a great way to quickly make great GUI applications for a variety of OS's. Thank you for your kind compliment, it is greatly appreciated.
