Hi iam using Mapguide opensource 2.0 ( with .Net 2.0 +IIS)
i have a problem while running the hello_map sample application i got an error that
Invalid argument(s):
        [0] = " "
The string cannot be empty.

 i got an error where it was happend .but i dont know the solution.

By debugging the hello_map application i found that
-------------------------------------------------------------------
    NameValueCollection serverVars = Request.ServerVariables;
    String platform = serverVars["SERVER_SOFTWARE"];
    String queryStr = serverVars["QUERY_STRING"];

    NameValueCollection requestParams = Request.HttpMethod == "GET" ?
Request.QueryString : Request.Form;


String mgSessionId = requestParams["SESSION"];
    String mgLocale = requestParams["LOCALE"];
    String mgMapName = requestParams["MAPNAME"];
-------------------------------------------------------------------------------------------------
in the above code i got platform as null, and queryStr as null and requestParams as also nulls coming.

plz tell me the  solution if anybody  Knows.



Regards,
Padmini.
