is this possible ? overridable and not overridable ??

[maged]

u have just noticed something and for just curiosity i need to know what that mean.

in my code i have this code

dim cmd as new sqlcommand 
'execute some codes with the sqlcommand
dim NewCode as long 
newcode = cmd.Parameters("@newcode").Value   'here is the important line

in design mode , when i stop my mouse pointer on the .value part the tooltip which appears write this line ((public overridable notoverridable property value)). now this is the tooltip that describes the Value proprty which i am standing on with my mouse, for this i have no problems. but the problem is how can the value property be overridable and not overridable in the same time.

am i mising something
