--------------------------------------------------------------------------------
HTTP Error 400 - Bad Request.
--------------------------------------------------------------------------------
Version Information: ASP.NET Development Server 8.0.0.0
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)
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
Dim tempid As ResourceIdentifier = New ResourceIdentifier("layout",
OSGeo.MapGuide.MaestroAPI.ResourceTypes.WebLayout, conn.SessionID)
Response.Redirect("/mapguide/ajaxviewer/WEBLAYOUT=" &
Server.UrlEncode(tempid)
