[mapguide-users] Losing Session ID

Tue Apr 10 14:34:50 EDT 2007

You could try setting session variables. I also found that in IIS settings
you can change the default 20 minute timeout to 60 minutes (or match your MG
session) for best results.

Set: Session["sessionIdSaved"] = sessionId;
Get: Session["sessionIdSaved "].ToString();

When i´m going to put these line into i get a error:

Compiler Error CS0103 

The name 'mgSessionId ' does not exist in the current context

the code is like this:

String mgSessionId = GetParameters()["SESSION"];

try
{
    // Initialize the web-tier and connect to the Tux Site using
    // the Tux session identifier stored in PHP session state.

    InitializeWebTier();

    MgUserInformation userInfo = new MgUserInformation(mgSessionId);
    MgSiteConnection siteConnection = new MgSiteConnection();
    siteConnection.Open(userInfo);

    // Create a ResourceService object and use it to open the Map

    MgResourceService resourceService =
siteConnection.CreateService(MgServiceType.ResourceService) as
MgResourceService;
    MgMap map = new MgMap();
    map.Open(resourceService, "Siel660355");

    //MgLayer layer = GetLayerByName(map, "ParcelMarker");
    //showClearButton = (layer == null) ? false : layer.GetVisible();

catch (MgException mge)
{
    Response.Write(mge.GetMessage());
    Response.Write(mge.GetDetails());
}
%>

    <form method="post" action="suche2.aspx">
    <p><input name="IDNR" type="text" value="<%=
DropDownList2.SelectedValue%>" /></p>
    <!-- <p><input name="sessionID" type="text" value="<%= mgSessionId%>"
id="Text1" />&nbsp;</p> -->
    <p><input type="submit" value="Suche" /></p>
    </form>   

</body>
</html>

Maybe i have to write the GetParameters Function in another way?

it´s like this

NameValueCollection GetParameters()
{
    return Request.HttpMethod == "GET" ? Request.QueryString : Request.Form;
}

Michael

Try putting <input type="hidden" name="SESSION" id="SESSION"
value="<%=mgSessionId%>" /> in the server-side form. When your page posts
back, it should now be part of the Request.Form collection, which can be
retrieved by GetParameters()
