vb.net - Public connection string inaccessible -

i have imported own database connection file doesn't dbconnectdbostr string

any ideas?

imports pirelli.dbpirelli  partial class _default     inherits system.web.ui.page       sub page_load(byval sender object, byval e eventargs) handles mybase.load         dim strcmd string         dim dbcmd sqlcommand         dim oconn sqlconnection         dim dbreader sqldatareader           oconn = new sqlconnection(dbconnectdbostr) 

connection file:

imports system.data.sqlclient   namespace pirelli       public class dbpirelli         'database server - enable 1         public const strservername string = "[server]"  'dev          public const dbconnectdbostr string = "uid=[user];password=[pass];database=[db];server=" & strservername & ";connection timeout=60;"      end class  end namespace 

i getting error:

description: error occurred during compilation of resource required service request. please review following specific error details , modify source code appropriately.   compiler error message: bc30451: name 'dbconnectdbostr' not declared.   source error:  line 21:  line 22:  line 23:         oconn = new sqlconnection(dbconnectdbostr) line 24:  line 25:         oconn.open()  

since you're not dealing instance of dbpirelli class, should make classs static , call namespace using:

namespace pirelli      ' in vb static class called "module"     public module dbpirelli         'database server - enable 1         public const strservername string = "[server]"  'dev          public const dbconnectdbostr string = "uid=[user];password=[pass];database=[db];server=" & strservername & ";connection timeout=60;"      end module  end namespace 

....

' since you're importing namespace pirelli.dbpirelli, don't need ' call namespace had indicated oconn = new sqlconnection(dbconnectdbostr)
