I just updated from 4.6 to 4.8 (RC3)...after a long guess...as my projects are rather complex.
But the new functionality is really great! And I believe updating my projcts is it worth while.
Before updating, I was about to implement reprojection myself (NTv2), but found that projections are now part of Mapwingis.
So, how to use the functions? As the documentation is at least sparse, I have no clou how to reproject a shape.
Is it possible to reproject a coordinate/point/shape/shapefile from DHDN (projected) to WGS84 (geographic)? (I know this is a rather complicated task...)
And how to do it?
I am using Access and VBA.
The 'trick' is to use the EPSG code to get the projection string.
Don't forget to read the new documentation: www.mapwindow.org/documentation/mapwingis4.8

thank you for the fast reply.
So far I've got it working now. But....
prj.ImportFromEPSG (EPSGCode) doesn't work.
So that prj.ExportToWKT responds with an empty string.
Using prj.ImportFromESRI (WKT-String) works like a charm.
But it would be nice to have EPSG working.
Another question: Is there a way to just reproject a single coordinate pair (without generating a shapefile)?
