Title: NetTalks Maps markers dissapearing
Post by: Alberto on November 06, 2020, 04:09:45 AM

Ive twiked a little the demo making 300 markers.

Just run it and move the map left to right, right to left and after 4 or 5 moves the icons disappears.

Attached goes the demo

What version of Draw?

Release notes for 4.26 on November 2 say "Fix: Icon file could be left open"

I know of this fix, because Bruce made it to try solve this issue but it still happening.

reading that many markers, off the disk, apart from anything else, is going to be a bit slower.
You would be best off doing
net.SetMarker('cs'&m#,-lat$,lon$,'~MapPinBlue.ico')     
and then adding MapPinBlue.Ico to the solution.

That said, I'll continue to investigate why the call to load the icon off disk is failing.

I'll have a draw update that mitigates the problem (which appears to be in the DOS driver), but even with that the odd marker may still be missing. The longer-term solution is to switch the draw code to use StringTheory, but that's a bigger job I can't do right now.

The best solution is still to use Icons linked into the solution.

Thanks Bruce, will try adding it as a resource, but this means I need to force the user to use only some icons.
