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

[Suman Chatterjee]

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#.

Hi Suman,

I suspect
System.Configuration.ConfigurationManager.AppSettings["C:/ms4w/Apache/ht
docs/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

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.

 

Suman
