Hi,
i tried ur updated version of code
my code was
Dim host As New
Uri("http://localhost/mapguide/mapagent/mapagent.fcgi")
Dim conn As New HttpServerConnection(host, "Administrator", "admin",
"en", True)
'You have to change the string below to point at a valid WebLayout
Dim weblayout As WebLayout = conn.GetWebLayout("Library://Filebased
data/Layout/layout.WebLayout")
Dim mapdefinition As MapDefinition =
conn.GetMapDefinition(weblayout.Map.ResourceId)
'Modify the initial view of the weblayout
weblayout.Map.InitialView = New MapViewType()
weblayout.Map.InitialView.Scale = 2000 'Zoom to 1:2000
weblayout.Map.InitialView.CenterX = (mapdefinition.Extents.MaxX -
mapdefinition.Extents.MinX) + mapdefinition.Extents.MinX
weblayout.Map.InitialView.CenterY = (mapdefinition.Extents.MaxY -
mapdefinition.Extents.MinX) + mapdefinition.Extents.MinY
'Obtain a unique session based id for the temporary weblayout (which
is a copy of an existing WebLayout)
Dim tempid As ResourceIdentifier = New
ResourceIdentifier(Guid.NewGuid().ToString(),
OSGeo.MapGuide.MaestroAPI.ResourceTypes.WebLayout, conn.SessionID)
'Save the layout, otherwise you can't reference it
conn.SaveResourceAs(weblayout, tempid)
'Open the viewer, and use the temporary layout, since the map only
exists in the
'current session, we must use that session, and NOT supply
username/password
'BEWARE: The session belongs to the Administrator account, so the
user gets full access to MapGuide (delete, modify, etc.)
Response.Redirect("/mapguide/ajaxviewer/?WEBLAYOUT=" &
Server.UrlEncode(tempid) & "&SESSION=" & Server.UrlEncode(conn.SessionID))
but i got an error that
Server Error in '/maestro' Application.
--------------------------------------------------------------------------------
HTTP Error 404 - Not Found.
--------------------------------------------------------------------------------
Version Information: ASP.NET Development Server 8.0.0.0
i think this maybe with "data not found" problem
but i have an Filebased data package in the
C:\program files\mapguide opensource 2.0\server\packages
1) then what will be the problem?
Regards,
Padmini.
