[RESOLVED] Is it possible to nest properties ?

In this case I have a point (HexLocation) which I want to get/set as property for my class.

VB.NET Code:

Private HexLocation As Point
 
    Public Property Location As Point
        Get
            Return HexLocation
        End Get
        Set(HexLocation As Point)
        End Set
    End Property

Then this works just fine afterwards:

VB.NET Code:

Hexagon1.Location = New Point(0, 0)

The problem comes when trying to modify only one of those two values, for example:

VB.NET Code:

Hexagon1.Location.X = 33

"This expression is a value and cannot be the target of an assignation."
So I then tried nesting properties but created a demon:

This didn't work either:
Attachment 175625
I can't simply have it as a public variable because I need to execute code when it is modified but not enough for it to require a method, I think, so I'm lost.

The Point data type is a Structure, and therefore cannot be edited. Instead you need to replace it with a whole new value, eg:

Code:

---

    Public Property X As Integer
...
        Set(NewX As Integer)
            HexLocation = New Point(NewX, HexLocation.Y)
        End Set

---

Thanks for the tip, that would work great except it would be acessible this way:

VB.NET Code:

Hexagon1.Location = New Point(0, 0)
Hexagon1.X = 33

But I would want X to be a member of Location as such:

VB.NET Code:

Hexagon1.Location = New Point(0, 0)
Hexagon1.Location.X = 33

In that case either create a new Class with similar properties to Point (and use that instead of Point), or possibly call the new property LocationX (and live without the dot).

Thanks I created a structure for it similar to point but with the property blocks I needed.
Also the last reply got sent twice mb.

Can you show us your code because I don't see how that could work either.
