Hi all,

I've published a new release candidate for MapWindow v4.8.8.
Download it here:

Please test it thoroughly and let me know if you find any blocking issues.
If all goes well the final version will be released in two weeks time.
That version will also be placed on the OSGeo-Live DVD that will be handed out during the FOSS4G in Nottingham, GB.

Thank you Paul. I have been searching for five hours now on how to rotate labels. I remember a few years ago I was able to do this with a "rotation" field in the table.
How can I make that work again?

where can I download a complete set of source code plus proper version of DLLs and/or OCX.

I tried Map6 and dotSpatial, Unfortunately, Map6 has a crash bug that is hard to pin down and dotspatial demomap lacks the features of MapWin4.

I downloaded several other map type projects, eg LineSiter, Marine Life as example code. I was able to use these project to build Map6 without compiler error. Unfortunately, none of these project has the "query" function I needed,

If I can get a Map4x project built and run, I will be able to debug the crash bug for Map6. Can you help. I just need a workable set of Mapwin source code and proper DLLs/OCX.

MapWindow4 uses MapWinGIS.ocx as mapping engine. MapWindow6 uses DotSpatial as mapping engine.
These are two different applications.

To get the source code of MapWinGIS you can go to
If you go to the download tab you can get the ocx-only installer. you can drop the ocx on your own form.

The current source code of MapWindow4 is available at

Thanks for your reply. I can't get passed the crash issue of Map6. Will try the ocx routine to get a better understanding of the Map engine,
