Re: [mapserver-users] Object reference not set to an instance of an object
Hi Suman, I suspect System.Configuration.ConfigurationManager.AppSettings[“C:/ms4w/Apache/htdocs/mapservertest/Addison.map”] evaluates to null in your case, and therefore the ToString() operation on the null reference is failing which problem is not related to the MapScript library itself.

RE: [mapserver-users] Object reference not set to an instance of an object
Hi, I corrected my problem. Actually, I changed the code a little bit. Const string MAP_FILE = "c:/inetpub/wwwroot/Addison.map" Map= new mapObj(MAP_FILE) The line System.Configuration.ConfigurationManager.AppSettings["C:/ms4w/Apache/ht docs/mapservertest/Addison.map"] Is throwing error. No idea what it is trying to do. Now my application is working fine in IIS and C#.

RE: [mapserver-users] Object reference not set to an instance of an object
Hi Suman, Check your web.config file- You probably have an entry similar to: . In your code you want to create the mapfile object by reading the mapfile path from web.config. So what you need to do is: mapObj map= new mapObj(System.Configuration.ConfigurationManager.AppSettings["mapfile"].toSt ring()) (or whatever the variable in the web.config is called) You don't really want to use a constant to point to the mapfile...
