Question

let say i have that

Structure myStruct     Public myPoint As Point     Public myBool As Boolean End Structure 

how to I make a copy / clone of that structure?

I fixed that issue now, example of the code I was using:

    Dim myStruct(1) As myStruct      myStruct(0).myPoint = New Point(10, 10)     myStruct(0).myBool = True      Dim myCopy(1) As myStruct     myCopy = myStruct     myCopy(0).myBool = False     myCopy(0).myPoint = New Point(11, 11) 

with that, both variable was changed

I had to do

    myCopy = CType(myStruct.Clone, myStruct()) 

and another question, if that structure is used, let say, 10,000 times, should I created a class instead?

Answer 1

You’re looking at 12 bytes per structure, so passing it around as a struct is cheaper than creating a word-sized reference to it on heap (in other words, using a class)

If you need to access all 10,000 at once, creating an array of them will happen on the heap even if they are structs.

Copying the struct is as easy as creating declaring another struct of the same type and assigning the first to the second.
