[mapguide-users] Mapguide beta 2.4: quick plot on a basic layout from .net app does not work

Thu Apr 12 05:07:56 EDT 2012

Hi list,

I've just downloaded Mapguide 2.4 beta and tried to compile a very simple
.Net c# application. 
My target is to use the great new feature "QuickPlot" on my basic layout
(this layout type is a must for me, I have an application based on this).
But I have problems on using QuickPLot from a .Net app.

You can see below the code for the very simple single class Default.aspx.
I've created an IIS "Application folder"
http:\\localhost\mapguide\MapGuideSample and I execute my app from there.

My problem is that:
- if I preview from Maestro my web layout
(Library://TBDemoMesoccoCan/BasicLayout.it.WebLayout) I can use QuickPlot.
- but if I execute this simple app on the same web layout QuickPlot is not
responsive; I can open the dialog, but it does nothing. I can't see the
rectangle on the map and if I press "Generate" button, nothing happens. No
errors are displayed.

                // Initialize a session and register a variable to hold the
                // session id, then initialize the Web Extensions, connect
                // to the site, and create a session.

OSGeo.MapGuide.MapGuideApi.MgInitializeWebTier(@"C:\trash\MapGuideSample\MapGuideSample\webconfig.ini");

                MgUserInformation userInfo = new
MgUserInformation(defaultUser, defaultPassword);
                MgSite site = new MgSite();
                site.Open(userInfo);
                sessionId = site.CreateSession();

                idFMap.Attributes["src"] =
@"http://lptop-franz7vmwin7/Mapguide/mapviewernet/ajaxviewer.aspx?SESSION="
+ sessionId + "&WEBLAYOUT=" + webLayout;
            }
            catch (Exception ex)
            {
                Response.Write(ex.Message);
            }
        }
    }
}

Thanks in advance for any help...
