Reference to a non-shared member requires an object reference

Visual Studio 2008

Visual Studio 2005

You have referenced a non-shared member within your code and failed to supply an object reference. You cannot use the class name itself to qualify a member that is not shared. The instance must first be declared as an object variable and then referenced by the variable name.

Error ID: BC30469

To correct this error

Declare the instance as an object variable.
Reference the instance by the variable name.
