I just realized your SetButtonInfo was shared, as are your public fields.
This would imply that you can ever have 1 value in them at a time...yet you
want to declare an array of them. My guess is that you don't mean for them
to be shared...but fell into the trap of making them shared one of at a time
to get it quasi-working. This is what your class should look like (unless I
misunderstand the context, which is highly likely):
Do note that changing from shared to not is a pretty big change, so you
should learn the difference between the two before blindly accepting what
I'm saying..both are legitimate, depending on what you are doing

Thanks. And you are right, I probably should make SetButtonInfo my
constructor. The reason I didn't do that is because I don't know how (I
was never really taught how to make constructors in VB.NET). If you could
give me a simple example, I would appreciate it. Thanks.

dim ButtonList(10) as NavButtonInfo
ButtonList(0) = new NavButtonInfo
ButtonList(0).SetButtonInfo(...)
seems though like SetButtonInfo should be your custructor instead so that
you can do:
ButtonList(0) = new NavButtonInfo("homeindex", "Life With Nate",
"/index.aspx", Nothing)
If you don't know the size of the Array consider using an ArrayList.

news:OV***************@TK2MSFTNGP10.phx.gbl...I have an array declared as follows:
Dim ButtonList() As NavButtonInfo
and a Class defined as follows:
Public Class NavButtonInfo
Public Shared name As String
Public Shared text As String
Public Shared URL As String
Public Shared parentname As String
Public Shared Sub SetButtonInfo(ByVal name As String, ByVal text As
String, ByVal URL As String, ByVal parentname As String)
NavButtonInfo.name = name
NavButtonInfo.text = text
NavButtonInfo.URL = URL
NavButtonInfo.parentname = parentname
End Sub
End Class
I am adding data to my array using the following code:
ButtonList(0).SetButtonInfo("homeindex", "Life With Nate",
"/index.aspx", Nothing)
When I build and run my application, I recieve an error that tells me
the following:
[NullReferenceException: Object reference not set to an instance of an
object.]
I think I must be doing something wrong or forgetting something when I
add data to the array, but I am not sure what. Can anyone tell me what I
am forgetting? Thanks.
