Re: [mapguide-users] MapGuide Selection and UniqueID Determination
Thanks Kenneth, That helps if we have the definition of an identity column. ie how does FDO determine this? I assume (hope) it is not just having a FDO IsAutogenerated() value as obviously a database could have a unique column that is key but not from a sequence. SHP and SDF generically get a FeatId autogenerated through the provider but this is not the case for foreign database schemas.

[mapguide-users] Fusion query()ing from any zoom level
I'm trying to use the javascript query function. Take this fictional example,
executed from inside the task pane:
Var options = {};
Options.layers = 'roads_layer';
Options.filter = 'road_width 5';
Parent.Fusion.getWidgetById('Map').query(options);
This works nicely when the roads_layer is actually visible, but not when the
map is zoomed out far enough. What I finally want to achieve is: User clicks on
an asp.net generated list of objects - query and select - zoom extents to
selection.

[mapguide-users] Printing Shortcomings Especially Legend Rendering
The quality of print output has been talked about before. I'm investigating what options there are to improve this. Perhaps the main issue is the legend output. With both the AJAX and DWF viewer, the legend is rendered with layers set to not display in the legend included, and Group headings included even if these are don't include any visible layers. Besides looking rather messy, this behaviour also means that a complex map with many layers/groups soon overflows the legend area. The API only sems to have one method dealing with the legend, RenderMapLegend, and this seems to be the call that produces the behaviour already described. There doesn't seem to be any methods that allow greater control. I'd be interested to hear from others on how they may have overcome these problems.

[mapguide-users] Adding a new Coord Sys
I'm trying to add a new coordinate system to MGOS 1.2 (or 2.0, haven't been able to do it in either one). I tried to do every logical operations I could think of. First I go in C:\Program Files\MapGuideOpenSource\Server\nad and open the EPSG file in Wordpad. I add the following 2 lines at the very end: # Google Maps 900913 +proj=tmerc +lat_0=0 +lon_0=36 +k=0.999600 +x_0=50 +y_0=1000 +ellps=WGS84 +datum=WGS84 +units=m +no_defs Second, I go in C:\Program Files\MapGuideOpenSource\Server\data and open epsg.wkt in Wordpad. I add the following line at the very end as well: 900913,PROJCS[Google Maps,GEOGCS[unnamed ellipse,DATUM[unknown,SPHEROID[unnamed,6378137,0]],PRIMEM[Greenwich,0],UNIT[degree,0.0174532925199433]],PROJECTION[Mercator_2SP],PARAMETER[standard_parallel_1,0],PARAMETER[central_meridian,0],PARAMETER[false_easting,0],PARAMETER[false_northing,0],UNIT[Meter,1],EXTENSION[PROJ4,+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m [EMAIL PROTECTED] +wktext +no_defs]] After doing that I restart the service, then I go in the MapAgent test page (mapguide/mapagent/index.html) and I attempt to see if this new code is available through the Coordinate System calls.

I'm also sure it's not a problem with the PROJ4 definition, as I have tried to use an existing, working coordinate system and just make my 900913 system be that definition, and it didn't work.

Re: [mapguide-users] Printing Shortcomings Especially Legend Rendering
I have taken the long way, and implemented a decent legend generator in C#. Unfortunately I cannot give it away, as it belongs yo my employer. It works by imitating the legend control in the basic viewer, and fetches each of the little preview items. It does scale checking and more for the layers. Once all have been retrieved, it builds a single png with a sane layout (ea. no empty groups etc). It would be nice if there was such a method in MapGuide, especially if it was also possible to display legend items for features that were actually visible in the map. ea.: if the Lakes layer is on, but I have zoomed in on a building with no lake in sight, it should not display Lakes in the legend. As for general printing, I have also taken the long way and created a full upscaling function that can upscale a map's components to fit a larger resolution. I use this for generating high quality PDF files. As before, it belongs to my employer. Again, it would be nice if this was avalible in MapGuide (both upscaling, as well as PDF generation).

RE: [mapguide-users] Adding a new Coord Sys
You are 1/2 way to having this setup. :) The changes you have done below have updated the server to understand the coordinate system you have added, but you still need to update the web tier. Make the exact same changes to the same files in the C:\Program Files\MapGuideOpenSource2.0\WebServerExtensions\www folder. This is not obvious from the web tier test pages that you are using as the coordinate system APIs only hit the web tier API and don't actually round trip to the server.
