Last post by John Z - November 22, 2025, 10:13:55 PMEvery project, all 8, I have on SourceForge are open source, granted one or two might be a version or two behind due to computer replacements and getting the git or SVN access working again.
Every project on Pelles Forum has had the source included except Linecounter+. The code is such a tangle, works well, but spaghetti-fied it would not go over well
Maybe I'll fix it for the next activity.
So I fully, and always support open source, but you open source something when it is finally finished IMO.
Anyway no worries, we are all in synch in reality I think.
The new sizer library code is posted can be used as a library or just include the sources directly.
Pelles Help file indicates he could be interested -
"The full source code for resizer.lib (and resizer64.lib) is included, so if you have a better idea how to handle this - just implement it (but it would be nice if you inform me, so I may include the changes in some future version).
"
So maybe he can use some ideas from this effort.
