Hi, I have a problem in invoking a method in the class I have a Database class say DBAccess, in that I have a method to be invoked, I have created object to that class in this manner Dim objDBAccess as DBAccess when i used like this objDBAccess.GetData() Sometimes I am encountered with the error message "Object Reference not set to an Instance of an Object". I have overcomed by instantiating the object as Dim objDBAccess as New DBAccess I want to know how in some access the First statement itself worked fine and sometimes it failed on invoking that method.:confused:
