Refresh table performance regression since MapInfo v2023?

Posted By Jonas Nordlund 09-29-2026 05:40
Found In Egroup: MapInfo Pro \ view thread
Hi! We're receiving reports from our clients and can verify that SERVER REFRESH on SQL Server tables (downloaded + linked with cache) can become several times slower to refresh than in MapInfo v17, especially over networks where the SQL Server instance runs on a separate server as the app. Is this ...

WMS data sets differentiated by path, not domain

Found In Egroup: MapInfo Pro \ view thread
We're running into a few issues with consuming three different maps from a WMS service. They each have their own username and password, and they are differentiated by path, not host name. So e.g. https://wms.example.com/map/1 with user 'abc' and https://wms.example.com/map/2 with user 'xyz'. The ...

Late reply, but thanks a lot! I've been sidetracked by other aspects in our application but I'll try this solution ASAP! :-) ------------------------------ Jonas Nordlund Software Developer Norconsult AB Sweden ------------------------------

Thanks for the quick reply. This looked very promising and just what I was looking for because the tile server indeed reports 404 for the (0,0,0) tile. I've checked with the service license and it's open source & CC-BY-SA so if it helps, I can give you the actual server. The map is a snow mobile ...

Hi! We're currently struggling with a tile server that returns 404 Not Found for tiles that are missing / out of bounds, in this case outside of Sweden. So the tile server actually doesn't hold the entire world. A few tile rendering libraries or tools (like OpenLayers, Leaflet..) either simply ...

RE: Least Cost Path analysis

We just discovered this code sample by using GDAL and scikit-image that might work for us as a plan B in case we still need to turn to external tools. It also illustrates what we want to do here: Raster Layers - Python GDAL/OGR Cookbook 1.0 documentation (pcjericks.github.io) ------------------------------ ...

Least Cost Path analysis

Hi! We're working on aiding our users with least cost path analysis, that is, calculating a shortest path as a polyline through a weight raster e.g. GeoTIFF given a start and end point. Has anyone done this kind of work with MapInfo and can provide us some pointers? I've looked around online and ...

Thank you, I didn't look close enough because I disregarded RibbonInterface but I see there are many samples I missed there. I'll have a look! ------------------------------ Jonas Nordlund Software Developer Norconsult AB Sweden ------------------------------

Adding background tasks

Hi! I've been unable to find documentation on how to add a MapInfo Pro background task via the .NET API. The type IMapInfoApplication has a collection of BackgroundTasks. So, if MIApp is an instance that implements that interface, I can do: MIApp.BackgroundTasks.AddTask(task); However, how do I even ...

RE: MS Office update - MapInfo Pro v17.0.4.3 link to Access database no longer working

Found In Egroup: MapInfo Pro \ view thread
Just a quick follow up for anyone coming across it: We fixed this by linking to our Access tables with Server Link Table rather than Register Table with Type Access. Maybe it could also be fixed with Register Table with Type ODBC and a Microsoft Access connection string. I never tried that, but ...

Hi! I'm unsure how this relates to MapInfo Access support working until Office is updated? You're saying that MapInfo needs to have been originally installed with administrator rights for it to survive Office updates? ------------------------------ Jonas Nordlund Software developer Norconsult ...

First, I had completely missed the SetDllDirectory call. Interesting -- I'll definitely look into that further! Thanks for the sample code. The missing map reparenting support in MapInfo Pro 64-bit COM rings a bell and that did cause it to not be an option for our flagship GIS application. However, ...

Yes, I noticed this recently too. I heard something about it could be due to OSM's change of server software which is more picky about the http headers that MapInfo is using?

Very interesting and exciting to see this! I think it's the correct approach to use existing IDE's to not have to reinvent the wheel, but rather use powerful extension systems like in VS Code! (great choice of editor) It basically "just" needs three things for me to think it being vastly more useful ...

Hi! The "official approach" here has always been a bit unclear to me, and now I remembered to ask! Background: We build multiple import & export routines to/from our GIS application that is using MapInfo as its map engine. E.g. importing details daily from customer or billing systems into MapInfo tables, ...

OK, so read only support and that from SHP files. I hope that TAB and/or server databases (as in supported by MAPINFO_MAPCATALOG) will get the opportunity to store elevation data in the future. Unfortunately separate point layers or other methods to get here are suboptimal as you get two different sources ...

Formats with Z and M value read/write support for individual nodes in polylines?

Hello! I understand that MapBasic supports e.g. ObjectNodeZ/M to read this per-node data along a polyline, and you can check for data source support with ObjectNodeHasM/Z. I have a few questions though: Which formats or databases that MapInfo Pro supports also supports this data, including with write ...
