PAHLabs Blog goes Live

 Welcome All! Today with this post the PAHLabs Blog goes Live. It is a goal of mine to share with others my passion in Software Development, Coding and Application Design.  I plan to use this blog to reach out to those of like minds, and especially those wanting to learn. Though in my 40+ year career in software development I have written many, many software languages, this blog is mostly going to focus on PureBasic.  I have an accompanying website ( https://www.PAHLabs.com ) where I have both free and licensed software products, developed using the PureBasic Language.  You can find out more about PureBasic at  PureBasic Here in my blog, I will begin explaining how these applications were written, and to share with you how I develop software.   The first thing about software development I wish to share with you is that software development is all about solving problems. A software program is nothing more than a solution to a problem.  As with ALL ...

How to build this without writing Code

I'm not sure if I should do this now, because I have not explained a number of additional aspects to the code, but for those of you who are interested.  The foundation of what I shown you here, IS the foundation of code my PBXClassBuilder-Standard generates for you.  And I truly mean generates  for you. You can have all this code generated for you without writing a single line of it yourself. Now PBXClassBuilder-Standard is not perfect, it is approximately 90=95% accurate. And I am constantly tweaking it edging this number ever higher. To use PBXClassBuilder-Standard, You should start with Forms already laid out and built.  Within PBXClassBuilder-Standard you use intuitive screens to define your table structure, while linking the Table Fields to their intended form Fields.  Then link the Tables together as Parent Child, and finally you simply click buttons to generate the code, Including the SQL Code to create the tables. The Whole development process, post For...
