[mapserver-users] Object reference not set to an instance of an object

[Tamas Szekeres]

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.

Best regards,

Tamas
