[mapserver-users] getExtent(c#) with Postgis data ...

[Matej]

Tamas, thank you.

I have tried using Npgsql and mapscript_csharp and I can successfully connect to the database, but now I suppose I need .map files saved locally to get things working? 

Actually I am in the middle of choosing whether it is better to use SharpMap or Mapserver's C# libraries for building a desktop app? What are your (and everybody's else's) recommendations and suggestions about it?

Thank you very much,
Matej

  Yes it's definitely the case.

  You application should set a reference to the managed mapscript_csharp.dll assembly and it will implicitly load furher unmanaged dlls to provide the desired functionality.

    Hi,

    this might not be directly connected but I am planning to build a client desktop app which should be able to connect to the PostGIS db that is running on the remote server and display objects from it / add new etc.

    Is this possible in C# with fwtools without the need to have the Mapserver running on every client computer?

    Thanks and sorry for interrupting,
    Matej

      Paul,

      You can refer to the ogrinfo C# sample application in the gdal source tree:
      http://trac.osgeo.org/gdal/browser/trunk/gdal/swig/csharp/apps/ogrinfo.cs

      Best regards,

        Thanks Tamas...

        But now I´m a little lost... Am I supposed to create a OGR layer?
        Do you have any sample how to get extent´s layer using OGR?

        P

            Where can I find ogr_csharp.dll ?

            Thanks Tamas!

              Unfortunately this function is not implemented by the MapServer postgis driver, you might want to use the OGR C# API (ie. ogr_csharp.dll)  for this purpose.

                All value from getExtent (Postgis layer) is : 3.4028234663852886E+38

                Is it a bug?

                  Why don't? That function have already been exposed for layerObj with the following signature:

                  public rectObj getExtent(void)

                    Hello, It seems that getExtent (c#) is not implemented...
                    Any other solution to get extent of a layer using mapscript?
