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"]. toString()) (or whatever the variable in the web.config is called) You don't really want to use a constant to point to the mapfile...

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#.

Best regards, Tamas 2009/7/8 Suman Chatterjee <schatter...@addisontx.gov> Hi all, I am trying to develop an application in C# (VS2005) with mapscript. I saw the material of Paolo. But I am facing a problem In the line mapObj map= new mapObj(System.Configuration.ConfigurationManager.AppSettings["C:/ms4w/Ap ache/htdocs/mapservertest/Addison.map"].toString()) It is generating the error " Object reference not set to an instance of an object" How can I correct this? If anyone helps me in correcting it, it will be great.
