    How can I find out if a structure is empty?

    Ahh, I had this problem before and I guess I solved it, but I forgot....

    You can't use the = operator for structures, and I guess you cant use Is Nothing... So lets say I have a structure, how can I check to see whether it is empty or not?

    Structures CAN'T be empty! - a structure must contain at least one instance member variable or Event declaration.

    You could put a boolean value inside the structure to indicate whether the data has been set.
