More correctly the new version should have a different behaviour but doesn't. See the change history help article for 6.10LTS, Changed item number 5.

The new behaviour of ListSize and MapSize on a freed item doesn't work, it halts with an error the same as previous versions. Tested on PB6.10LTS x86 and x64, ASM and C backends. Debug "* Array *" Dim MyArray.I(5) Debug ArraySize(MyArray()) FreeArray(MyArray()) Debug "" + ArraySi...

In the return value section:
(for example after @freearrayor if its initialization has failed).

Use enumeration: I'd suggest being shorter on the "Window" bit for conciseness ie Win, Wdw or even Wn, and use longer and always descriptive names. So never #Window_1 but always something like #WinLogin, #WinSchemaWarning, #BtnOk, #BtnCancel, #MnuFile... I also assign enumeration names to...

There must be one somewhere. The compiler will halt with an error, if there isn't. It's possible that you can't currently see it though. The IDE supports code folding which may be causing parts of the code to be hidden. Check for small + marks in boxes adjacent to line numbers. These indicate sectio...

You can do basic network monitoring with SysInternals' Process Monitor tool which you can download for free from: https://learn.microsoft.com/en-gb/sysinternals/downloads/procmon .

Is there a solution floating around here that can preserve the order of fields, or at least allow me to re-sort them once I get them from the JSON library? InsertJSONStructure and ExtractJSONStructure will "round-trip" properly if used correctly with the same Structure definition. You can...

PDF output for Windows is new for 6.10, it's Mac/Linux only in previous versions. The example shown in the help article for PdfVectorOutput() won't actually work (on Windows). It tries to write to a read only folder and fails with no error message. It needs updating. Try this, it should work properl...

I'm reasonably confident in saying the scenario you describe will leak and you should 'Finish' every query (but I haven't tested it). The application must finalize every prepared statement in order to avoid resource leaks. See https://www.sqlite.org/c3ref/finalize.html . PostgreSQL is even more emph...

DatabaseColumnSize isn't updated after a DatabaseUpdate only a DatabaseQuery (also true for the other DatabaseColumn*). You can check AffectedDatabaseRows() after an update to see how many rows were modified. If the result of DatabaseUpdate is non-zero, the value of DatabaseError is the empty string...

Something like this? The gadget generates a #WM_NOTIFY message when a scroll starts with a NMHDR\Code value of #LVN_BEGINSCROLL or #LVN_ENDSCROLL when one ends. An #WM_NOTIFY/#LVN_ENDSCROLL message occurs when an arrow is clicked or a non-grip (page scroll) click occurs. I've then used GetScrollInfo...
