i discussed this topic with Jerry start of this year for a while.
Since you released a new stable version, i took the time to test that behaviour again.
Prefetch_Test_db.zip (308.7 KB)
Attached you can find an ms access database, that contains one form, together with a small shapefile containing tree-locations.
When opening the form, it creates a background tile-Layer from a locally running osm-tile-server (windows linux subsystem is really great), - but this can easiely be changed in Form_Load to a common osm-tile server -, reprojects the shapefile, creates a thematic map based on a field in the shapefile and displays the results.
The plan is, to give the user the opportunity to store the background tiles locally, to be able to copy it all to a Laptop with no internet connection. For this i implemented the Prefetch-Method to fill a local tile-cache with the tiles of all zoom-levels.
So open the database, open the form (- to see the messages of the callback-interface you need to open the integrated vbe and the immediate window) and then click the prefetch-button.
For me, this crashes ms access reliably.
I would be very happy to get this component running reliable in an ms access form.
In spring this year even clicking on the identify-button on the form and double-clicking one tree reliably crashed ms access, but this doesn’t seem to happen with this new version, good.
Any ideas and help is very welcome.
I’ve a customer who would even like to pay a developer to get it this component in a whole stable in ms access, just get in contact with me, if you’re interrested.
So have a nice weekend
and best regards
