Hi,
Thanku very much for ur help
i tried this code
but i got an error in the line
Dim tempid as ResourceIdentifier = new ResourceIdentifier(Guid.NewGuid(),
OSGeo.MapGuide.MaestroAPI.ResourceTypes.WebLayout, con.SessionID)
because of this Guid.NewGuid()
1) Actually what is this?
2) Which paramater we have to pass in this place instead of Guid.NewGuid()

<pre wrap="">To build a map, you must have all the components:
1. FeatureSource, references data
2. LayerDefinition, references a FeatureSource 3. MapDefinition,
references multiple LayerDefinitions 4. WebLayout, references a
MapDefinition
All these items must be in a repository (either Library or Session),
otherwise they can't be referenced.
When you write that you want to "create a WebLayout programatically",
do you want to create ALL the above items, or do you have layers and
featuresources?
(1) If you want to generate a WebLayout ResourceID, you should use:
Dim res As New ResourceIdentifier("Filebased data/Maps/mapdata",
ResourceTypes.WebLayout)
If you want to read the name of an existing MapDefinition from
another layout, you must do:
Dim weblayout as WebLayout =
con.GetWebLayout("Library://mylayout.WebLayout")
Dim res as String = webLayout.Map.ResourceId
(2) I don't understand the question.
(3) The MapDefinition is an Xml document. Inside, it references
layers, which references featuresources, as described above. It is
very slow to do this, so when you open a map in the browser, the xml
is transformed into a binary object. This object contains all the
info from the MapDefinition and some info from the layers and
featuresources.
You need to know this, because if you try to toggle layer visibility
in the MapDefinition, nothing happens. In short, the Runtime Map is a
binary object that you can manipulate using the MapGuide (and
Maestro)-API, and it only works for a displayed map.
Upon startup, the Runtime Map is identical to the MapDefinition it
was created from.
A short example of using an existing WebLayout:
Dim host As New
Uri(<a class="moz-txt-link-rfc2396E" href="http://localhost/mapguide/mapagent/mapagent.fcgi">"http://localhost/mapguide/mapagent/mapagent.fcgi"</a>)
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 =
con.GetWebLayout("Library://mylayout.WebLayout")
Dim mapdefinition as MapDefinition =
con.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(Guid.NewGuid(),
OSGeo.MapGuide.MaestroAPI.ResourceTypes.WebLayout, con.SessionID)

<pre wrap="">Hi,
Thanks for u r reply
actually i wrote the code as
Dim host As New
Uri(<a class="moz-txt-link-rfc2396E" href="http://localhost/mapguide/mapagent/mapagent.fcgi">"http://localhost/mapguide/mapagent/mapagent.fcgi"</a>)

"admin", "en", True)
Dim res As New ResourceIdentifier("Filebased
data/Maps/mapdata",
ResourceTypes.MapDefinition)
Dim mapId As String = res.ResourceId
with that i got the map resource id.
But actually to run the application the url in the browser must be
like
<a class="moz-txt-link-freetext" href="http://localhost/mapguide/mapviewerajax/?WEBLAYOUT=Library%3a%2f%2fF">http://localhost/mapguide/mapviewerajax/?WEBLAYOUT=Library%3a%2f%2fF</a>
ilebased+data%2fLayout%2flayout.WebLayout
1) How can i get this weblayout (like
Library%3a%2f%2fFilebased+data%2fLayout%2flayout.WebLayout)
programmetically
2) I want to redirect to the ajax viewer sample application through
asp.net (like given by u )
Response.Redirect("/mapguide/ajaxviewer/?WEBLAYOUT=...resourceId
for
your WebLayout...&USERNAME=Anonymous&PASSWORD=");
3) Can u plz tell me the purpose of runtime map (actualli iam in
configusing
state)
