I’ve been awakened!
In the span of a few weeks I have solved a couple of long standing problems I’ve had. And made decent advances in other unrelated areas. I set Julia aside for a year because I wasn’t understanding a problem related to bytes and Unicode that I didn’t think should be a problem. Solved or at …
Lazarus file I/O skeleton
Pretty much got this file I/O GUI skeleton the way I want. There’s a place to enter both input and output files. Then proceed to a input/output loop where I can read an output file preform various operations then write output. This is the basis of many things I do. It took my longer to …

They appear fairly active with new releases, Currently on V7.2.14. It looks like I have a program that uses written back in Oct 2017. It’s supports many SQL flavors, …
Lazarus file I/O screen commands
I did SQLite processing first a seemingly harder topic than selecting files for basic file I/O. And I believe it is a more advanced topic. I just assumed there would be your standard looking file selection controls in Lazarus. However they’re not your standard looking file selection controls. Or perhaps they exist and I didn’t …
Lazarus SQLite3 access
Making progress. Below is a form that accesses a SQLite3 zip code database. I was easily able to bring the form up with all records available by embedding a SQL statement in a SQL property in the SQLQuery control. Added a Florida button to only show Florida records, just to play with changing the selection …
