[mapguide-users] Re: Dynamically Setting Initial Map Position and Scale

[pwong]

I know this thread has been going awhile, but I'm running into the same issue
as previous posts.  The sample is in php, I'm using C#.  I think I have the
equivalent in C#.  When I run the application.  I get an error "Invalid
repository type.".  I have set the web layout to have a "custom initial
extent" in Studio.  Using Ajax Viewer.

Here's the code.

	String sessionId = "";
	string WlXML = "";

    
MapGuideApi.MgInitializeWebTier(@"E:\MapWorld\Autodesk\MapGuideEnterprise2011\WebServerExtensions\www\webconfig.ini");
    
    	MgUserInformation cred = new MgUserInformation();
    	cred.SetMgUsernamePassword("User", "UserX");
    
    	MgSiteConnection site = new MgSiteConnection();
    	site.Open(cred);
    
	MgSite site1 = site.GetSite();
        sessionId = site1.CreateSession();    
    
    	String strwebLayout =
"Library://MapWorld_V1/Common/Layouts/MapWorld_V1_Basic_Layout_3.WebLayout";

        //Get an MgWebLayout object
        MgWebLayout webLayout = null;
        MgResourceService resourceSrvc =
site.CreateService(MgServiceType.ResourceService) as MgResourceService;
        MgResourceIdentifier webLayoutId = new
MgResourceIdentifier(strwebLayout);

        //create XML document to change values
        MgByteReader wlreader =
resourceSrvc.GetResourceContent(webLayoutId);
        WlXML = wlreader.ToString();
        XmlDocument doc = new XmlDocument();
        doc.LoadXml (WlXML);                    
	
	foreach (XmlNode Xnode in doc.GetElementsByTagName("CenterX"))
	{
		Xnode.InnerText = "-117.9202";
	}
	foreach (XmlNode Ynode in doc.GetElementsByTagName("CenterY"))
	{
		Ynode.InnerText = "33.8270";
	}
	foreach (XmlNode Snode in doc.GetElementsByTagName("Scale"))
	{
		Snode.InnerText = "2000";
	}	

   
   	//save the xml changes and read into memory
        MemoryStream StreamSave = new MemoryStream();
        doc.Save(StreamSave);
        byte[] byteArr = StreamSave.ToArray();            
        MgByteSource vByte = new MgByteSource(byteArr, byteArr.Length);

	//create a new weblayout with the changed weblayout data stream
        String SessionmapName = webLayoutId.GetName();
        String SessionWebLayout = "Session:" + sessionId + "//" +
SessionmapName + ".WebLayout";
        MgResourceIdentifier sessionResourceId = new
MgResourceIdentifier(SessionWebLayout);
        resourceSrvc.SetResource(sessionResourceId, vByte.GetReader(),
null);


And here's the Frameset that contains the map.

<frameset rows="45,*" border="0" framespacing="0">
  <frame NAME="FrameTool" SRC="/mapguide2011/MapWorld_V1/title_public.php"
SCROLLING="YES" MARGINWIDTH="0" MARGINHEIGHT="0"  frameborder="1">
  &lt;frame
src=&quot;/mapguide2011/mapviewernet/ajaxviewer.aspx?SESSION=&lt;%=
sessionId %&gt;&WEBLAYOUT=<%= sessionResourceId %>" name="ViewerFrame" />
</frameset>
