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

Re: [mapserver-users] getExtent(c#) with Postgis data ...
2009/4/8 Matej ma...@matnet.net 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? Not necessarily. You could also build up a map object from scratch and not save it in the filesystem if not required. You could also not save the map image just draw the contents of the imageObj and read the contents directly into a GDI+ bitmap. 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? I've already used Mapserver's C# libraries to create various .NET desktop applications and it worked pretty well. You might however create an example just to make sure about all the aspects before making the final decision. I'm not sure about SharpMap, isn't that a pure ASP.NET project?
