Tags: Microsoft, Office, office 2004

Hello,
i am using Outlook 2007 and C#.NET 2005 to search the contact from Outlook.
though i have developed the applciation and it is working fine but i have a problem with one of my laptop. in that i have installed office 2007.

i have tested this with office 2007 and also office 2003 on XP, Windows 2003 and Vista machines.
i am not able to understand the problem that i am getting. when i run my application on my laptop i get error "Object referecne not set to an instance of object".

i am attaching the Code snippet that i am using

in the code i am getting error between linenumber 101  and linenumber 104. linenumber is a variable which is assigend line number value to trace the linenumber where error occured.
