Text file and Timer
« on: November 05, 2025, 07:06:19 pm »
A little help please. I have a Timer and each tick I want to open file, write some data and close file.
Don't get it How to do it using Lazarus...

So I opened file using rewrite command before Timer procedure, but I can't close it within Timer body.

I tried to keep it opened, but it's limited. It worked about 4h (Timer 10sec) and then it stopped. Probably OS limit.

Thanks in advance!

Silly me! "Append, WriteLn, CloseFile" works perfect. This topic should be deleted. Sorry everyone.
