Something like this would do it with MaestroAPI (untested):<br>
<br>
MaestroAPI.ServerConnectionI con; //Needs initialization<br>
<br>
//Read the current resources<br>
MaestroAPI.WebLayout layout =
con.GetWebLayout("???.WebLayout");<br>
MaestroAPI.MapDefinition map =
con.GetMapDefinition(layout.Map.ResourceId);<br>
<br>
//Create the temp layer<br>
MaestroAPI.MapLayerType layer = new
OSGeo.MapGuide.MaestroAPI.MapLayerType();<br>
layer.ResourceId = "???.LayerDefinition";<br>
layer.Name = "Temporary layer";<br>
<br>
//Add it to the map<br>
map.Layers.Add(layer);<br>
<br>
//Generate a session based temporary id (will become
Session:<sessionid>//Random Map Identifier.MapDefinition)<br>
string tempMapId = new
MaestroAPI.ResourceIdentifier("Random Map Identifier",
MaestroAPI.ResourceTypes.MapDefinition, con.SessionID);<br>
<br>
//Save the modified map in the session repo<br>
con.SaveResourceAs(map, tempMapId);<br>
<br>
//Modify the layout to point at the temp map<br>
layout.Map.ResourceId = tempMapId;<br>
<br>
//Generate a session based temporary id, and save the
modified layout (will become Session:<sessionid>//Random WebLayot
Identifier.WebLayout)<br>
string tempLayoutId = new
MaestroAPI.ResourceIdentifier("Random WebLayout Identifier",
MaestroAPI.ResourceTypes.WebLayout, con.SessionID);<br>
con.SaveResourceAs(layout, tempLayoutId);<br>
<br>
//Open the viewer with the modified weblayout, that uses
the modified map<br>
Response.Redirect("/mapguide/mapviewerajax/?session=" +
Server.UrlEncode(con.SessionID) + "&layout=" +
Server.UrlEncode(tempLayoutId));<br>
<br>
You can rewrite the property access with the corresponding xml changes,<br>
and the GetResource/SaveResource with the corresponding function calls
to the<br>
MapGuide API, if you don't want to use Maestro.<br>
<br>
Instead of the "Random ... Identifier" strings, you should use
Guid.NewGuid().ToString().<br>

<pre wrap="">Hi,
thanks for your information but how do you make toYou have to create a
temporary WebLayout AND a temporary MapDefinition and then make the
temporary WebLayout point to the temporary MapDefinition.
Have you an example of code?

<pre wrap="">If you save to "Library://" the data will be modified permanently.
Normally the "Anonymous" user is not allowed to save to "Library://".
If you save to "Session:<sessionid>//" the changes will only be visible to
the current user. You must take care not to mix sessionid's.
I think you are trying to use the WebLayout from Library, that will not
work.
You have to create a temporary WebLayout AND a temporary MapDefinition.
Then make the temporary WebLayout point to the temporary MapDefinition.
(I think your code does this)
Then save both WebLayout and MapDefinition in "Session:<sessionid>//".
When you redirect, you should point to the temporary WebLayout.
As you pass in the sessionId, the viewer should be able to read it
correctly.

<pre wrap="">Hi,
I refresh my post! If you have an idea !!!
Sorry, I wanted to say that my c# code change the mapdefinitin in the
layout
for the current session;
if i use administrator user, it seems to me that my repositories is
modified
in maestro, no and i will not ?
For (Sample 1) my code is <a class="moz-txt-link-freetext" href="http://patxi.mayol.free.fr/ag_default3.aspx">http://patxi.mayol.free.fr/ag_default3.aspx</a>
here
For (Sample 2) my xml file is <a class="moz-txt-link-freetext" href="http://patxi.mayol.free.fr/test_after.xml">http://patxi.mayol.free.fr/test_after.xml</a>
here
Thanks

<pre wrap="">You mention "layout resource", but the message states a MapDefinition is
saved?
Anonymous can only save to the same session, only Administrator can save
across
sessions.
As for the parse error, your document is likely invalid.
For (Sample 1), can you post the related code?
For (Sample 2), can you post a binary copy of the document you are
trying to save?
