Hi all,

I want to connect from my winform to mapguide server to get an EPlot. The
first test is a simple test connection winform client like this.

private void Connect_Click(object sender, EventArgs e)
        {
            try
            {
                MapGuideApi.MgInitializeWebTier("webconfig.ini");
                MgUserInformation ui = new MgUserInformation("Anonymous",
"");
                MgSiteConnection siteconn = new MgSiteConnection();
                siteconn.Open(ui);
                MgResourceService resourceService =
(MgResourceService)siteconn.CreateService(MgServiceType.ResourceService);
                MgMappingService mappingService =
(MgMappingService)siteconn.CreateService(MgServiceType.MappingService);
                MgMap map = new MgMap();
                map.Open(resourceService, "map");
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.ToString());
            }

I've added a reference to MapGuideDotNetApi.dll in the project and put all
dll's necessary in the directory. So, I get this error:

- MG 1.1.0 : Invalid argument in map.Open(resourceService, "map"); // the
map name is correct! it seems that the map name is an empty string
